— Mothers for Peace warns legislators that an extension of Diablo Canyon would cost Californians more than $2 Billion

From Mothers for Peace

Mothers for Peace and its allies call on California Governor Newsom, Speaker Rivas and Pro Tem Limón and Legislators to halt backroom negotiations and hold full public hearings before any vote to extend the nuclear plant’s life to 2045.

SAN LUIS OBISPO, CA — A backroom deal is taking shape in Sacramento that could keep the Diablo Canyon Nuclear Power Plant running until 2045—and stick California taxpayers and ratepayers with billions of dollars in costs and risk. Mothers for Peace, along with more than fifty other environmental and consumer organizations, is demanding that any proposal to extend the plant’s operations beyond its agreed-upon 2030 closure date be subject to full public hearings, independent fiscal analysis, and open legislative debate.

The coalition has formally written to Governor Gavin Newsom, Assembly Speaker Robert Rivas, Senate Pro Tem Toni Limón, and members of the California Legislature, warning them not to repeat the closed-door process that generated Senate Bill 846 in 2022. That last-minute deal extended Diablo Canyon’s operational life to 2030 and has already proven financially damaging to Californians.

“We’ve seen this movie before—a last-minute deal and no public input that has Californians left holding the bill, Linda Seeley, Mothers for Peace spokesperson, said. “Extending Diablo Canyon for another 15 years will cost billions more in public funding, create long-term ratepayer obligations, and cause serious safety risks. Californians deserve transparency, not another deal negotiated in the dark,” she added.

The warning from SB 846

Mothers for Peace, which has fought to close Diablo Canyon for more than 50 years, points to SB 846 as a blueprint for what goes wrong when the Legislature operates behind closed doors. The bill was introduced, negotiated, and enacted in the final days of the 2022 legislative session, with no meaningful public review or policy committee deliberation.

The consequences are already severe. The state’s $1.4 billion loan to support Diablo Canyon operations is effectively spent—approximately $1.33 billion has been disbursed directly to PG&E, and there is growing evidence it will never be repaid. To add insult to injury, a University of California, Santa Barbara study released recently, found that PG&E, Diablo Canyon’s owner, inflated the capital upgrade and operational costs used to justify the deal. And SB 846’s failure to reconstitute the plant’s Unitary Tax has left the San Luis Coastal Unified School District with a $10 million budget deficit.

The loan is only the beginning. Layered on top are a $100 million annual management fee paid simply for keeping the plant running, performance payments, volumetric payments projected to yield PG&E an additional $1.4 billion, and a $300 million ratepayer-funded Liquidated Damages Account. Together, these mechanisms represent more than $2 billion in additional public exposure beyond the original loan, while shifting nearly all financial risk away from PG&E and onto ratepayers and taxpayers.

Even with potential federal Department of Energy support, analysts project taxpayers could still be responsible for at least $659 million in unrecovered costs—and this is just through 2030. No estimates are available for the costs beyond that date.

All of this while PG&E posted a record profit of $2.59 billion in 2025—its third consecutive year of record earnings—as California ratepayers already pay some of the highest electricity rates in the nation.

A deal taking shape behind closed doors

Despite the Legislature’s policy committee deadline looming, no bill has been publicly amended to include a Diablo Canyon extension. However, there is still time for a bill to become the vehicle for a deal to include the extension. Alternatively, the extension could emerge as a last-minute trailer bill in the June budget, bypassing policy committees entirely. Both scenarios, the groups argue, would be just as unacceptable as the SB 846 process.

State Sen. Ben Allen, chair of the committee on energy, utilities and communications, expressed concern about a backroom deal. He told KQED: “if there is a need to keep Diablo online, I want to have real frank conversations about what we’re doing to improve clean energy buildout so that we won’t be so reliant on this money pit that requires subsidies by ratepayers statewide, not just PG&E customers.”

Safety and fiscal risks demand open debate

A 15-year extension would also leave unresolved serious safety concerns, including reactor embrittlement, spent nuclear fuel management, and seismic risk as the plant sits on a web of earthquake fault lines.

“SB 846 didn’t just hand PG&E a financial windfall—it stripped away the oversight designed to protect the public. Expedited permitting and curtailed environmental review mean state agencies cannot fully evaluate what they’re approving,” Diane Curran, attorney for Mothers for Peace, said.  These unresolved safety issues—reactor embrittlement, seismic risk, spent fuel with nowhere to go—aren’t just safety concerns. Under this deal’s structure, every one of them is also a financial liability that lands on taxpayers and ratepayers, not PG&E,” Curran explained.

Mothers for Peace is calling on the Legislature to:

  • Hold full policy committee hearings in both chambers on any Diablo Canyon extension proposal.
  • Conduct budget committee review given the detrimental fiscal implications for taxpayers and ratepayers.
  • Commission independent analysis of all safety, environmental, and fiscal risks, including seismic risk, reactor embrittlement, and spent fuel management.
  • Ensure meaningful public participation and transparency before any vote is taken.
  • Reject any last-minute gut-and-amend legislation or end-of-session budget maneuvers that bypass proper deliberation.

“The question before the Legislature is simple: will California once again enter a deal negotiated in the dark that places the financial burden on taxpayers and ratepayers while shielding PG&E from risk? Californians deserve better,” Seeley said.

— 2025 reports on health impacts of living near nuclear power plants

From Mothers for Peace

Before We Extend Diablo Canyon, We Owe Our Children Clear Answers

Those of us who live in San Luis Obispo County take pride in our community. We value clean air, open space, strong schools and a safe place to raise children. That is part of what makes this region special. It is why so many of us chose to live here and why we work to protect what we have.

Which is why repeated public health warnings deserve careful attention — not dismissal.

Concerns about health impacts near Diablo Canyon are not new. A March 2, 2014 report titled “Report on Health Status of Residents in San Luis Obispo and Santa Barbara Counties Living Near the Diablo Canyon Nuclear Reactors” by Joseph Mangano, MPH, MBA, examined cancer and other health indicators in communities closest to the plant. That report identified elevated rates of certain cancers and recommended continued monitoring and further study. More than a decade later, comprehensive long-term health monitoring still has not occurred.

Recent research strengthens those concerns.

In December 2025, Harvard University published a study, “Residential proximity to nuclear power plants and cancer incidence in Massachusetts, USA (2000–2018)”, which examined cancer incidence near nuclear power plants in Massachusetts. Researchers found elevated cancer risks among residents living closer to reactors, particularly older adults, and documented that risk declined with distance. The authors emphasized the importance of continued epidemiologic monitoring as reactors age and licenses are extended.

That study did not focus on California. But its findings reinforce concerns raised here at home.

A peer-reviewed study published November 12, 2025, “Worsening Infant Health in San Luis Obispo County and the Diablo Canyon Nuclear Reactors,” by Joseph Mangano, MPH, MBA, examined long-term local health trends. It found that outcomes once better here than the California average have steadily eroded.

Before Diablo Canyon began operating, our county’s infant mortality rate was 16 percent lower than the state average. Now, that advantage has disappeared. Premature births, once well below the state rate, rose above it. Birth defect rates in recent years were more than double the California average, ranking third highest among large counties. Childhood cancer rates, once significantly lower than statewide levels, have moved closer to them.

These are not one-year spikes. They are long-term trend changes. And they matter because they affect our youngest and most vulnerable residents.

Taken together, the 2014 and 2025 Mangano studies and the recent Harvard findings point in the same direction: communities living near operating nuclear reactors deserve rigorous, transparent and ongoing health evaluation. When warning signals appear across different studies, time periods and states, the responsible response is investigation.

San Luis Obispo County does not fit the profile of a community struggling with the usual drivers of poor birth outcomes. We have relatively low poverty and unemployment, high education and income levels and good access to medical care. Many known risk factors are lower here than statewide. Yet our early-life health advantage has faded.

No one is claiming these findings prove cause and effect. But public health protection does not require absolute proof before asking serious questions, especially when children’s health is involved.

Before any extension moves forward, San Luis Obispo County deserves an independent, site-specific public health assessment conducted transparently and reviewed publicly. That is not anti-nuclear. It is pro-accountability — and it is what our children, grandchildren, great-grandchildren and all future generations deserve. 

If we are considering operating Diablo Canyon for another 20 years, we must first really know what the last 40 years have meant for the health of families who live here. How many premature births, birth defects, childhood and adult cancers are we willing to accept if Diablo Canyon continues running for another twenty years?

Decision-makers are moving quickly to extend operation, and so must we. Join our efforts to protect Central Coast Communities for future generations.

URGENT CHALLENGE

Diablo Canyon nuclear plant was scheduled to retire in 2024 and 2025. However, Senate Bill 846 – passed in 2022 – has enabled extended operation. State and federal subsidies have been granted to support this effort. Pacific Gas & Electric Company has applied to the Nuclear Regulatory Commission for a 20-year license extension, although SB 846 asks for only 5 years.

THE ISSUES

The Nuclear Regulatory Commission (NRC) exempted Pacific Gas & Electric Company (PG&E) from its Timely Renewal Rule, disregarding its own rules by approving continued operation of the Diablo Canyon reactors past their expiration dates without the required environmental reviews or opportunity for public hearings.

Unit 1’s reactor vessel was built with faulty material so is vulnerable to embrittlement. An embrittled reactor vessel can shatter like glass and cause a catastrophic meltdown. Despite this, PG&E has not tested for embrittlement for over 20 years – and the NRC has approved the exemptions.

The California Public Utilities Commission has approved extended operation without all the information required by SB 846 – and despite evidence that Diablo’s energy is not needed to avoid summer blackouts. There is new seismic evidence to show that the earthquake faults that run directly under the plant are vertical thrust faults, meaning they could cause much more ground motion than formerly estimated.

Diablo’s Once-Through Cooling System is out of compliance with the Clean Water Act. The facility circulates 2.5 billion gallons of seawater each day, releasing it back into the ocean 20º warmer and killing more than one billion fish in early life stages.

Extended operation of Diablo Canyon means the generation and onsite storage of even more high-level radioactive waste in an active seismic area.

— Mothers for Peace demands PG&E test Diablo Canyon Unit 1 for embrittlement

Update from Mothers for Peace, May 25, 2025:
PG&E has now pulled the capsule, but it will take 12-18 months to test the capsule for embrittlement.

From Mothers for Peace
March 18, 2025

Diablo Canyon Nuclear Plant Unit 1’s reactor vessel was built with faulty material, so it’s vulnerable to embrittlement. An embrittled reactor vessel can shatter like glass and cause a catastrophic meltdown. Despite this, PG&E has not tested for embrittlement for over 20 years.

PG&E has now committed to removing Capsule B from Unit 1 to test for embrittlement during the upcoming April outage. Previous attempts to remove this capsule have been unsuccessful.

On March 18, 2025, Mothers for Peace sent a letter to the CEO of PG&E, Patti Poppe, setting forth its expectation that Capsule B will finally be removed during this upcoming April outage and subsequently tested for embrittlement so we will learn if it’s safe to operate.

We are compelled to send this letter because of previous failures by PG&E to test the Diablo Canyon Nuclear Plant for embrittlement. We agree with the 9th Circuit Court of Appeals when they state:

We share Petitioners’ concerns about the public health and safety implications of repeatedly postponing Capsule B’s withdrawal. It has been about two decades since PG&E withdrew and tested a surveillance capsule from the Unit 1 reactor vessel—and even longer since a surveillance capsule withdrawn from Unit 1 generated credible data. Although Unit 1’s operating license has now officially expired, the reactor continues to operate under the NRC’s “timely 10 renewal” rule because PG&E has submitted a license renewal application. San Luis Obispo Mothers for Peace, 100 F.4th at 1056–58 (citing 10 C.F.R. § 2.109(b)). Capsule B remains a key source of data for the license renewal period. Under the current schedule, PG&E is slated to remove Capsule B in the spring of 2025 and use it to inform the company’s pending license renewal application for Unit 1. Any further delay in Capsule B’s withdrawal will mean that PG&E lacks a critical data source about the future integrity of the reactor vessel, without which a future license renewal may be subject to legal challenge.

— May 15, 2025: Top seismologist urges immediate shutdown of Diablo Canyon nuclear reactors citing “unacceptable risk” of an earthquake-triggered meltdown   

From Mothers for Peace

Award-Winning UCLA Earthquake Scientist Files Declaration to the NRC Requesting Shutdown of Diablo Canyon.

SAN LUIS OBISPO, CA – MAY 15, 2025 – A leading earthquake expert has called for the immediate shutdown of California’s last operating nuclear power plant, warning that a proposed decision by the NRC dismissing seismic risks at Diablo Canyon is incomplete and illogical and fails to address significant evidence that seismic risks are too high to meet federal safety standards. 

In a formal declaration submitted today to the Nuclear Regulatory Commission (NRC) Petition Review Board (PRB),  Dr. Peter Bird, Emeritus Professor of Earth Sciences at UCLA, states that continued operation of the Diablo Canyon Power Plant (DCPP) presents “an unacceptable risk of a serious earthquake-caused accident,” and that the NRC is obligated to shut it down under its own safety guidelines.

Dr. Bird’s declaration criticized the NRC for refusing to open an enforcement proceeding sought a year ago by environmental organizations. Instead, the NRC parroted unsupported and illogical claims by PG&E that the reactors are safe to operate and ignored Dr. Bird’s strong evidence and analysis demonstrating that the risk of an earthquake-caused core damage accident at DCPP is high enough to warrant immediate shutdown under the NRC’s own guidance.  

 “I continue to hold the view that the risk of a serious earthquake-caused accident at DCPP is unacceptable, and that immediate shutdown is warranted under NRC’s existing guidelines,” wrote Dr. Bird, a globally recognized authority in earthquake modeling with nearly five decades of experience.

Submitted on behalf of petitioners San Luis Obispo Mothers for Peace (SLOMFP), Friends of the Earth (FoE) and the Environmental Working Group (EWG), Dr. Bird’s declaration criticized the NRC for failing to conduct a competent and independent review of “grave concerns regarding the severe risk of an earthquake-induced accident during continued operation of Diablo Canyon nuclear reactors.” 

Dr. Peter Bird now serves as Professor of Geophysics and Geology, Emeritus at UCLA with 49 years of experience in seismic activity and earthquake modeling. Holding a doctorate in Geophysics from MIT, Dr. Bird is the founding architect of the Global Earthquake Activity Model (2015). 

The Bird declaration to the NRC warns that PG&E’s modeling for seismic activity “assumes that a majority of large earthquakes affecting Diablo Canyon are strike-slip and disregards the significant contribution of thrust faulting earthquake sources under the Diablo Canyon site.”

The nuclear reactors at Diablo Canyon, owned and operated by Pacific Gas & Electric (PG&E), were slated to close in 2024 and 2025 when its operating licenses were set to retire because the plants would eventually become “too expensive to operate” compared to available renewable energy resources. The “Joint Proposal” to shut Diablo Canyon, signed by environmental groups, unions, and PG&E was certified by the CA Public Utilities Commission (CPUC) in 2018. It did not address the unacceptably high risk for a seismic-induced reactor meltdown. However, the reactors’ licenses were extended after California Governor Gavin Newsom brokered a deal with PG&E, offering a $1.4 billion taxpayer-funded subsidy to keep the DCPP operational. 

Hallie Templeton, an attorney for FoE, said: “Allowing Diablo Canyon to operate without a competent and independent review of the seismic risks addressed in the petition puts millions of California residents in danger and risks a major radioactive disaster, akin to Fukushima, along the California coast. PG&E can’t say they haven’t been warned.”  

Diane Curran, legal counsel for SLOMFP, said: “We are very disappointed with the NRC’s proposed decision to allow DCPP to keep operating without a full review of the significant seismic risk to the reactors. It would be irrational and irresponsible for the NRC to permit PG&E to operate DCPP, especially with an aging and deteriorating Unit 1 reactor vessel, without addressing the concerns brought forward by one of the world’s top seismic experts. Listen to the science!”

Bernadette Del Chiaro, Senior Vice President, California at EWG, said: “The potential environmental and human health consequences of a major radioactive disaster along the California coast, similar to the 2011 Fukushima Daiichi incident, are simply unacceptable. It is imperative that all possible precautions are taken to ensure the structural integrity and operational safety of a nuclear facility located in an area with ‘unacceptable risk of earthquakes. The risks highlighted in the petition warrant an unbiased and expert evaluation to determine the true extent of the potential dangers to Californians. To keep Diablo open without this crucial review would place countless lives in jeopardy.”

— Gov. Gavin Newsom tricked California, voided November 2 shutdown at harmful, aging Diablo Canyon

October 31, 2024

Halloween Fright: Thanks to a trick instead of a treat by Governor Newsom, an aging nuclear monster still haunts the Central Coast of California 

November 2 was set to mark the closure of Diablo Canyon Nuclear Power Plant Unit 1, but SB 846 extended the aging reactor’s life through 2030. New data from the Governor’s office on renewable battery storage shows there’s no need for Diablo.

San Luis Obispo, CA — November 2 was meant to deliver a long-expected treat to Californians: the closure of Unit 1 nuclear reactor at Diablo Canyon Nuclear Power Plant on the expiration date of its 40-year license. But thanks to a surprise trick by Governor Gavin Newsom played on the California State Legislature in 2022, the reactor will continue operating indefinitely without critical seismic upgrades and safety tests. The reactor’s owner, Pacific Gas and Electric Co. (PG&E), has also failed to install cooling towers essential to meet Clean Water Act standards for protecting marine life.

Until September 2022, California residents could anticipate the timely closure of Diablo Canyon’s reactors. Under a hard-fought 2016 agreement between PG&E, labor unions, environmental groups, and others, Unit 1 was set to shut down on November 2, 2024, followed by Unit 2 in 2025. But in a last-minute move on September 1, 2022, pressured by the Governor, the State Legislature passed Senate Bill 846, extending Diablo Canyon’s operations to 2030. PG&E, meanwhile, went further, applying for a 20-year license extension—going four times beyond the five years specified in SB 846.

Despite the Governor’s warnings of power outages without Diablo Canyon, no such disruptions have occurred. Even during this past summer’s record-breaking heat waves, California’s energy grid met demand, demonstrating the success of renewable resources and battery storage. This stability shows that California can maintain a reliable grid without a hazardous nuclear plant.

In fact, since the Legislature’s 2022 vote, California has rapidly expanded its renewable capacity. By October 2024, data from the California Energy Commission and Public Utilities Commission showed an estimated capacity of 13,391 MW of battery storage—well above the 2,200 MW produced by Diablo Canyon’s reactors. Touting these gains, the Governor’s office stated on October 15 that this growth of California’s battery storage capacity “marks a 30% increase since April 2024, underscoring the state’s swift progress in building out clean energy infrastructure, especially during a summer marked by record-breaking heat.” 

Linda Seeley, spokesperson for Mothers for Peace, remarked: “SB 846 prioritized an unfounded energy need over public health and environmental safety, disregarding both seismic risks and the growing embrittlement of Unit 1’s pressure vessel.” She added, “California has the tools to ensure reliable, clean energy through renewables and battery storage. We don’t need to compromise health and safety to keep the lights on.” 

Diane Curran, attorney for the group, stated that both PG&E and the Nuclear Regulatory Commission (NRC) have failed to ensure the safety of the embrittled Unit 1 pressure vessel, a critical safety component that holds the reactor core. “The NRC is also allowing Unit 1 to operate past Nov. 2 despite serious concerns that earthquake faults under Diablo Canyon, which were discovered after it was built, could cause a nuclear accident,” Curran said. 

She noted that the group’s concerns have been documented in testimony to state and federal regulators by Dr. Digby Macdonald, Professor Emeritus of nuclear materials science at the University of California and Dr. Peter Bird, Professor Emeritus of Geosciences at UCLA. For a detailed explanation by Dr. Bird of the seismic dangers facing Diablo Canyon, watch the video here.  

November 2 should have been the Halloween treat Californians deserved, not the trick we received. When Halloween is over, this monster will continue to loom, threatening the health, safety, environment, and well-being of residents of the Golden State.

— Did PG&E secretly build and operate a breeder reactor on the California coast?

Vistra Energy is demolishing part of the former PG&E power plant at Moss Landing in Monterey County, California, and building a large lithium-ion battery storage facility there. According to very credible reports from people that worked for PG&E and GE, GE built a breeder nuclear reactor for PG&E at Moss Landing in the late 1960s. If true, that could pose significant radioactive contamination risks to demolition workers and the surrounding environment. Demolition must be immediately halted.

The public isn’t aware that a nuclear reactor of any type exists or existed at Moss Landing, but according to sources, GE nuclear power division in San Jose designed and built a breeder reactor for PG&E at Moss Landing in 1968, and it began operation in approximately 1969. It was a very expensive reactor, and it was not for power generation. It operated until the mid to late 1970s when it was shut down for unknown reasons. The control room, and possibly the reactor itself, were underneath the #6 or #7 535-foot smoke stacks. There was an access stairwell to the underground reactor control room, with a metal railing surround. After the reactor was shut down, the control room access was still visible.

A former worker at Moss Landing witnessed small planes periodically flying through the steam of the smoke stacks, presumably taking air samples. That person was told the smoke stack emissions were only steam, but any reactor emissions might have been vented out the tall stacks.

When a person who helped build the reactor later went to work for PG&E in the 1980s and inquired about the reactor and how it was functioning, PG&E employees told the person, “It doesn’t exist,” and “Shut the f*** up or you’re finding a new job”. That next weekend, PG&E filled in the access stairwell with concrete and cut off the metal railing at ground level.

One former employee went to Monterey County Planning Department to research if permits had been issued for the reactor and didn’t find any record of permits. In response to FOIA requests, the NRC also did not find any responsive records on the reactor, meaning they have no records or they have no records they will disclose to the public.

A breeder reactor is for the purpose of making plutonium for the military and for nuclear bombs. PG&E and GE operated a breeder reactor together at Vallecitos beginning in 1957. This type of reactor does not produce energy. One source suggested the Moss Landing reactor was to make off-the-books plutonium.

If the reactor existed, it was operated by PG&E at the same time as the company was operating the Humboldt Bay Nuclear Power Plant, called by Science Magazine “the dirtiest of the nation’s power reactors” [1]. It would have had the same safety problems, the same lack of AEC/NRC oversight, and potentially the same high radioactive emissions and contamination to the surrounding area. The area around the power plant and underground, including any control room and ground water, may be highly polluted with radioactive elements including hot particles and plutonium, considered by experts to be the deadliest of poisons, with no safe level of ingestion or inhalation. Contamination would pose hazards to local residents, to the waterways and ocean, to groundwater, to agricultural products, and to workers on the site.

State, federal, and local authorities have been notified of the situation including NRC, DOE, CDC ATSDR, California DTSC, CalEPA, CDPH, Monterey County EHIB, and the Monterey County Board of Supervisors, but to date, they have taken no known steps to investigate the situation or have refused to do so. Nuclear and environmental experts, civic groups, non-profit organizations, and other resources have also been informed about this situation,

Meanwhile, Vistra Energy continues demolishing equipment and buildings at the site.

Action steps needed now:

— Demolition work at Moss Landing by Vistra and other companies must be halted immediately due to the danger to workers and the surrounding environment from possible contaminated equipment and buried radioactive materials, pending an investigation.

— A thorough and public investigation must take place immediately into the complete history of PG&E’s uses and facilities at Moss Landing and the existence and extent of any radioactive contamination there.

— Removal and remediation of any and all contaminated soils and machinery, including excavation, must be undertaken by licensed professionals with full transparency. And any soil and debris already removed must be tracked and dump sites notified of its possible contamination.

— If radioactive gases were vented through the smoke stacks, their level of radioactive contamination must be assessed.

— The risk of fire and explosion of the lithium-ion batteries onsite adds another element of risk to any onsite radioactive contamination and potential dispersal offsite. This may necessitate the shut-down of the battery energy storage facilities until an investigation is completed.

— 23 March 2011: Letter to California senator on Diablo Canyon NPP recertification in the light of Fukushima experience

Letter to Sen. Sam Blakeslee Regarding Diablo’s Recertification

by Cindy Sage
23 March 2011

I have some thoughts for you, as you go after Diablo’s recertification.

Let me tell you what it is like to fly from Singapore to Hong Kong to SF and back to SB in one day. Because of catastrophic radiation threats from ‘the safest nuclear reactors in the world’ in Japan.

Our daughter, her husband and 22-month old evacuated from Tokyo last Tuesday to Singapore via Osaka and Shanghai. They’ve lived in Tokyo for two years, and the baby was born there.

I flew to Singapore for a week to help them.

These are thoughts now, about California, coming back home. Flying back over the green hills of SLO and SB counties from San Francisco, you think “we don’t even have 160 miles between us and Diablo”. That is the distance between Tokyo and Fukushima’s Daiichi nuclear plant that now has four reactors in partial meltdown and thousands of spent fuel rods in empty cooling ponds seeping and belching radiation directly into the air and the seawater. The government acknowledges this will likely continue for weeks and months to come. And, the threat of full meltdown of one, or more, of these four reactors and/or the cooling ponds for spent fuel is not ruled out yet.

Tokyo has thirty million people in one city alone that cannot be moved, or properly informed because they will panic and bring further chaos to an overloaded government.

One hundred and sixty miles away is less than one day’s airflow up the SLO and Santa Ynez valleys to major population areas.

Remember the SB fires? Burning upslope and inland by day, and back downslope at night, carrying fire, smoke and ash in an endless zig-zag pattern? Remember only the rain could really stop the fires? In Tokyo, the rain will bring down the radioactivity. During the Gap fire, we sat at Playa Azul at an outdoor table, and the ash fall was so thick it coated the food and floated black in the margaritas. We had to leave the food on the table and go because we couldn’t breathe and couldn’t eat it.

For a week, people in Tokyo prayed that 160 miles was far enough away. Heck, its the distance from Bakersfield to LA, right? I heard that from seriously smart, educated Americans, waiting it out. But events have to unfold, and the chaos involved and unnecessary anguish are heartbreaking for the families. The slow leakage of information that prevents stampeding and improves the government’s ability to control events also sacrifices many in the process.

“Our expectations had a scientific basis, but conditions were exceeded.” VP of TEPCO, Tokyo Electric Power Company, March 23rd, CNN interview.

Based on the now-demonstrated failure of at least four of Japan’s nuclear reactors to withstand ‘design’ events that were calculated on the basis of only one catastrophic failure at a time, we know this kind of thinking is outdated and monumentally risky for California as well. Japan planned for earthquakes, but not multiple, cascading events that ran out of control, prevented planned emergency responses, and caused them to throw away the rule-book in favor of ‘hail mary’ passes like flooding with seawater, one helicopter squirt at a time. Japan’s TEPCO didn’t even realize for a week that they had cooling ponds running dry that held thousands of leaking radioactive spent fuel rods. Because they couldn’t even get into or close to their own plants to survey the damage.

Not until the effort was militarized, and people could be ordered to go into the hot zone did we begin to see the damage, and understand the colossal breaches of containment and destroyed plants and cooling equipment. That is not in the rule-book. They had no response. Now, Daiichi’s reactor 3 in chronic, uncontrollable release-mode, and it contains plutonium as well as radioactive cesium and iodine. The other three reactors are in partial meltdown, and even government press releases say they cannot rule out complete meltdowns as yet.

Japan continues to deal with the aftermath – major aftershocks, continuing loss of power, loss of back-up power, loss of triple-backup power, fires, radioactive meltdown and seepage, intentional steam releases of radioactive materials directly into the air to prevent catastrophic hydrogen buildup, inadvertent radiation releases from explosions that happen on a regular basis anyway, the spreading plume, the hopeful weather patterns carrying the radiation ‘somewhere else’, the inevitable recirculation of radiation back over Tokyo and central Japan, the lack of equipment to properly test air, water, food and the people evacuating the hot zones.

What pieces of information are reliable? What is the subtext of unfolding US Embassy and State Dept and military advisories? What ‘indicators’ do you hold out as the trigger for “what to do next”? Do you wait until the US government moves the USS George Washington aircraft carrier out of Yokohama as happened Monday, because it is SOUTH of Tokyo? Is that a bad sign? Do you wait for the US State Department to issue potassium iodide pills to all employees and their dependents as happened Monday? Or, the radiation is twice the infant limit in Tokyo groundwater as happened Tuesday? If you wait, will the trains and planes be full, and ticket prices quadruple normal fares – effectively prohibiting travel for families with kids? What can you believe? What is hype or spin? What does it mean when the evacuation zones seem to be based more on what the government can handle sheltering people, rather than what the radiation levels should be dictating? You can’t effectively evacuate 30 million people all at once, even if the exposures are extreme and otherwise dictate that it should be done immediately.

Getting, judging, and reacting to incomplete, conflicting and incomprehensible information is an impossible task for people in a crisis, who are also dealing with emergency flights, emergency housing, trains that don’t run, sick babies, traveling spouses, planes that are full, empty store shelves, bank accounts that cannot be accessed due to power outages, overloaded telecom systems that don’t work, aftershocks, grief, fear, passports that can’t be located, cell phones that are cancelled or don’t work in other countries, missed connections in foreign airports where there are no diapers, no food, no sleep, no information, wondering if/when people will not be allowed to fly if they test positive for radiation contamination. When is it too late to evacuate? IF you go back, can you get out again?

People with means and money have nearly insurmountable difficulties. People without means and money simply pray and go into deep denial. They are publicly praised by the government for their fortitude, while they can do nothing but await their fate with stoicism.

A week ago, military dependents and ex-pats in Tokyo working for US, German, French, Spanish and other international corporations were formally advised by their employers it would be prudent to evacuate Tokyo. But, there was no health threat. WHO said so.

Ticket prices skyrocketed in Asian countries. Booking evacuation flights and trains became very difficult to impossible. Families split up. Serviced hotel and apartment units in Hong Kong, Singapore and other flee-zones were snapped up by corporations for evacuated ex-pat families…. the one we stayed in went to 97% occupancy in a week.

These families are now trying to figure out if/when they can return. Hour by hour, day by day, parsing the messages in the media coverage. I did this yesterday. And, all last week. I’m still doing it this morning, by skype. Only uncertainty is certain.

Lessons learned? What I can tell you is that I think Diablo should be shut down now. Period. Taken off-line. The Hosgri fault, and perhaps other unrecognized faults, and the likelihood (not just the remote potential) for major earthquakes, tsunami, loss of cooling systems, and proximity to major population zones are clear indicators now that this plant should be mothballed.

The clear underestimation of design earthquake in the original Diablo design, and the failure to anticipate and provide credible protection against predictable, multiple, cascading natural disasters is basis enough not to recertify, and to take it off-line now. Germany is taking some of its older reactors off-line. Why not California?

We don’t get 30% of our power from nuclear in California. We have other options. Japan does not, so they have to accept rolling blackouts for the foreseeable future. They have to accept the long-term consequences including loss of transportation and public services infrastructure, food and water shortages due to radiation contamination, loss of industrial output, loss of communications, banking, and other vital services, contamination of beef and dairy herds and row crops, and embargos and bans by other countries on the import of leafy green vegetables and dairy products from Japan.

Try that on central coast farmers, ranchers, viticulturists and other growers in the agricultural industry.

Talk to Bakersfield, Fresno and the central Valley growers, too, because they’ll be in the hot zone as well.

Japan doesn’t even have enough meters to measure the safety of food and water. Most people shop everyday for foodstuffs and walk to get there. They have to go outside to live. To re-supply their tiny refrigerators.

When summer comes, can you imagine being inside with your kids, unable to turn on the air conditioning or get fresh air because of radiation contamination? Imagine this in 86 degree weather with 90% humidity?

That is best case, and assumes there is enough power for any air conditioning at all.

PG&E has a similar history of malfeasance and misleading regulators and the public as does TEPCO. The parallels are clear – both utilities have demonstrated failures in maintaining critical infrastructure, conducting required safety tests, and providing honest and timely information to regulators and the public about risks to health and safety. The time for wishful thinking is over.

Sam, you have no idea how comforting it is to know you’ve got the scientific and geotechnical background AND the political position to make this issue a front-burner.
