PG&E reports nuclear reactor welding leak at Diablo Canyon facility

EWG: Critical questions about coolant system damage go unanswered

SAN FRANCISCO – Pacific Gas & Electric found damage to part of a reactor cooling system at the aging Diablo Canyon nuclear plant in California, but it hasn’t yet answered key questions about the extent of the problem.

PG&E is the owner of the state’s last remaining nuclear power plant, and found the fault with the reactor coolant system during a routine inspection in October. PG&E detailed the damage in a report[1] to the Nuclear Regulatory Commission, or NRC, in December.

The power company says the system had a crack in the welding of the wall of Diablo Canyon’s Unit 2 reactor, which was shut down for refueling. PG&E says the presumed cause was fatigue, which was caused by vibrations at the facility indicating a weld defect. The utility says the damage meant the unit fell short of NRC operating requirements.

PG&E says it repaired the leak, and the public and plant workers were never at risk. But the utility’s filing with the commission raises several questions, including:

  • When was the affected weld last inspected?
  • When does PG&E believe the crack in the weld formed?
  • Why had the weld flaw not been identified?
  • What was the size of the leak when it occurred?  

“The communities near Diablo Canyon deserve to know the full details of the incident, how it happened, why it wasn’t discovered earlier and how long it took for PG&E to identify the damage to the reactor coolant system,” said Environmental Working Group President and California resident Ken Cook

“The main reason for shuttering this aging facility is the potential threat it poses to the public – and PG&E’s overall safety record across its vast service area in the state is among the worst of any power company in the country,” Cook said.

Diablo Canyon’s latest problem highlights ongoing concerns about the stability of the facility and shows why EWG and others are pushing to shut the plant down. 

Yet state and federal officials are trying to keep the aging facility operating beyond 2025, when it’s slated to shutter under the terms of a settlement carefully negotiated between PG&E, California and environmentalists.

Last September, at the urging of California Gov. Gavin Newsom, the state legislature approved Senate Bill 846, a law that will keep the plant operating for five more years, until 2030. It will also give PG&E a $1.4 billion loan to cover costs during that extra time.

In November, the Biden administration announced it will give PG&E more than $1 billion in federal funding to keep the plant operating past its scheduled 2025 closure date.

PG&E has also petitioned the NRC to fast-track its October 31 request to extend the license of the twin Diablo Canyon reactors. Four environmental organizations, led by San Luis Obispo-based Mothers for Peace, or SLOMFP, have sent letters to the NRC warning it would violate federal law if it accepts the proposal. The other groups that signed the letters are EWG, Friends of the Earth and Committee to Bridge the Gap.

“PG&E cannot have it both ways,” claimed SLOMFP Board President Jane Swanson. “PG&E stopped preparing the reactors for continued operation in 2016 and voided their license renewal. The company has spent the past six years preparing to mothball the reactors and has saved money by not investing in future operations. It is too late to get a license renewal before the plant must shut down.”

— Gavin Newsom’s protection of PG&E and Diablo Canyon

From Mothers for Peace

Governor Newsom has been carrying PG&E’s water for too long. When will it end?
July 8, 2022

Governor Newsom’s cozy relationship with PG&E has been ongoing since his run for San Francisco Supervisor in 1998. By now, contributions from PG&E add up to well over $10 million in support of his campaigns and ballot measures.  The company has also contributed hundreds of thousands to Newsom’s wife’s foundation. In return, Newsom has helped PG&E get away with murder, literally. And now, Newsom is proving his loyalty to the company by providing a runway for PG&E to keep Diablo Canyon nuclear plant open past its agreed-upon closure date of 2025. 

On June 30, the Department of Energy (DOE) bowed to Newsom’s plea to change the rules so Diablo could qualify for a portion of the $6 million of Civil Nuclear Tax Credits. The DOE also extended the application deadline until September 6, 2022, allowing PG&E ample time to apply. Newsom is no stranger to manipulating circumstances to help PG&E. After the Camp Fire, which killed 85 people in 2018, Newsom had his lawyers craft a bill, AB 1054. This 2019 bill essentially protected PG&E by creating a $21 billion fund to help utilities cover the cost of major wildfires started by their equipment and forcing customers to pay for half of the cost of the fund. The bill also enabled PG&E to obtain official state safety certificates for two fire seasons since the Camp Fire. Yet, three years later, a state report on the 2021 Dixie Fire indicated that the utility was negligent in its tree-removal program, which helped spark the fire, and that their response the day of the fire was “excessively delayed.”

Newsom benefited from $208,400 in political contributions from PG&E to help him win his 2018 run for governor. 

In response to the Supreme Court’s ruling weakening the EPA, Governor Newsom claimed that “California is taking bold action to further advance California’s progress toward an oil-free future and bolster the state’s clean energy economy.” Yet, at the same time, he convinced members of the State Legislature to pass a very climate-unfriendly Trailer Budget Bill. This legislation provides a $75 million allocation for the Department of Water Resources to purchase electricity from Diablo Canyon and hundreds of millions more for fossil fuel power plants.

Keeping Diablo open past 2025 breaks a hard-fought agreement between environmental organizations, labor, and PG&E. It puts the availability of renewable energy at risk, undercutting the state’s ability to reduce carbon dioxide and other climate-warming emissions 40% below 1990 levels by 2030 and achieve carbon neutrality by 2045. California does not need Diablo to ensure sufficient energy to prevent power outages or meet climate goals. To be clear, Diablo Canyon is closing because PG&E determined in 2016 that doing so would enable it to meet California’s renewable energy standard (RES) and emissions standards more rapidly and more cost-effectively.

Newsom’s coddling of PG&E and his maneuverings at the state and federal levels to keep Diablo running is all the more disturbing in that his motivations are based on the false narrative that these fossil and nuclear-fueled plants will prevent power outages. They will not. Energy consultant Robert Freehling explains it succinctly: “These plants were operating during the early 2000s energy crisis and in 2020. They did not prevent outages.” 

Timeline: PG&E’s disasters since 2010
ABC10 examined the disasters and wildfires caused by PG&E, starting with the San Bruno Gas Explosion in 2010 then jumping ahead 8 years to the Camp Fire.Here’s a look at the timeline of PG&E’s disasters by ABC10:2010… PG&E was convicted of six federal felonies, including obstruction of the investigation, stemming from the 2010 San Bruno Gas Explosion. The blast killed eight people. Due to this conviction, the company was placed on probation until 2022, paid a $3 million fine, and was sentenced to 10,000 hours of community service.

2017… PG&E started serving time on probation in 2017, and as a convicted felon, donated $208,000 to Gavin Newsom’s run for governor.

2018... Newsom wins the governor’s race in November of 2018. Three days later, the Camp Fire started, destroying the town of Paradise and nearby communities. The fire resulted in the deaths of 85 people. It was determined the company left  a hook hanging for nearly a hundred years until it broke, dropped a power line and sparked the fire.

2019… Problems with similar parts on a high tension power line are blamed for sparking the Kincade Fire. It burned more than a hundred homes in wine country. No one died, but it was close. Firefighters were injured while saving people. PG&E is fighting multiple felony and misdemeanor charges filed by Sonoma County in connection to the Kincade Fire.

2020… PG&E pleaded guilty to 84 felony counts of manslaughter, and one felony for sparking the Camp Fire through criminally reckless behavior. Three months after the court proceedings for the Camp Fire, the Zogg Fire broke out when a tree hit a PG&E power line in Shasta County. Four people died, including eight-year-old Feyla McLeod and her mother, both of whom burned to death running for their lives in a pickup truck. It’s an active homicide investigation and prosecutors recently announced they will be filing charges against PG&E and possibly officials who work there. The judge managing PG&E’s probation already found PG&E committed safety “violations” when PG&E’s contractors marked an unsafe tree leaning over the power line, but no one ever followed up to cut it down.

2021… PG&E’s legal obligation to find and cut trees threatening power lines is again under investigation for the Dixie Fire, which is still raging through communities ever since igniting on July 13. The fire started where a tree fell on a PG&E power line just a short distance up the Feather River Canyon from where PG&E sparked the Camp Fire. The question for investigators isn’t whether PG&E sparked the Dixie Fire, but whether PG&E is criminally responsible. That question hinges on whether PG&E should have found the tree and cut it before it fell.

— Former Prime Minister of Japan tells Gov. Newsom: Shut down Diablo Canyon ASAP

Mothers for Peace SLO

Former Prime Minister of Japan Sounds the Alarm on Diablo Canyon
Naoto Kan Advises Governor Newsom to Close Diablo Canyon Nuclear Plant ASAP

May 2022 – Naoto Kan was Prime Minister of Japan when the March 2011 Fukushima nuclear disaster began. Hearing that California Governor Gavin Newsom is considering extending the operation of the Diablo Canyon Nuclear Plant beyond its current license period, Kan felt compelled to contact the Governor, advising him to shut down the nuclear plant as soon as possible.

As a result of Naoto Kan’s experiences managing the triple meltdown catastrophe, he has become vocally anti-nuclear. As he explains in his memoir, My Nuclear Nightmare, “I came to understand that a nuclear accident carried with it a risk so large that it could lead to the collapse of a country.

“Eleven years on, the nuclear disaster in Japan is on-going. The government is set to release millions of gallons of irradiated water into the Pacific Ocean as early as next spring – angering citizens and governments worldwide.

Both Japan and California are seismically active and share coastlines with the Pacific Ocean. Fukushima Prefecture and San Luis Obispo County have many similarities, both communities relying heavily on agriculture, fishing, and tourism. Naoto Kan has a deep understanding of these shared risks and vulnerabilities. Thus, he is sounding the alarm on Diablo Canyon.

Carole Hisasue, Spokesperson for San Luis Obispo Mothers for Peace, states, “As history has clearly illustrated, nuclear accidents affect the entire world. We will all be safer when Diablo Canyon nuclear plant ceases operation.”

Full text of Naoto Kan’s letter to Governor Newsom:

May 12, 2022

Dear Governor Newsom,
I have heard that you have been considering extension of operations at the Diablo Canyon Nuclear Power Plant which is set to decommission in a few years. I was the Prime Minister of Japan at the time of the Fukushima Nuclear Accident and based on my experiences dealing with that disaster, I advise you to shut down the nuclear plant as soon as possible.

As you know, three nuclear reactors built along the Pacific Coast in Fukushima melted down after the Great Northeastern Earthquake and Tsunami of March 11, 2011 and released an enormous amount of radiation.

Until this accident occurred, I never thought a nuclear event in which there would be a meltdown such as this could happen. And yet, in reality, the earthquake cut off external power, the emergency diesel generators were damaged by the tsunami and stopped. All power to control the nuclear plant was lost, three reactors could no longer be cooled and that led to the unthinkable meltdown. An incredible amount of radiation was released and even now, 11 years since then, many of the former residents of the areas around the nuclear plant are still in evacuation.

From my perspective, as someone who has personally experienced this accident, I believe that all nuclear power plants should be decommissioned as soon as possible and that we should move toward renewable energy, such as solar and wind, for all our power needs. This is why I am writing to you today.

I have enclosed the English version of a book I wrote about the Fukushima accident. I hope you can find the time to read it.

Naoto Kan 94th Prime Minister of Japan

Here is Naoto Kan’s letter in Japanese:

カルフォルニア州知事 キャビン・ニューソム 様
私は2011年、福島原発事故が発生した際に、日本の総理大臣を務め ていた菅直人と申します。現在カルフォルニア州で数年後に廃炉予定 のディアブロキャニオン原発について運転延長が検討されていると お聞きしました。私の福島原発事故を経験した立場から、原発はでき るだけ早く停止されることをお勧めします。
ご存じのように日本において2011年3月11日に発生した東日本大 震災と津波によって、福島県の太平洋沿岸に建設されていた3基の原 子炉がメルトダウンを起こし、大量の放射能を放出しました。
私自身この事故が発生するまではメルトダウンするような原発事 故は起こらないと考えていました。しかし実際には地震によって外部 電源が途絶し、さらに緊急用のディーゼル発電機が津波をかぶって停 止しました。そのため原発をコントロールする全電源が喪失し、3基 の原子炉は冷却できなくなりメルトダウンを起こしたのです。多くの 放射能が放出し、事故から11年経過した現在でも原発の近隣からは多 くの住民が避難しています。
事故を経験した私としては、できるだけ早いうちにすべての原発は 廃炉すべきであり、太陽光や風力発電によって必要な電力すべてを発 電する方向に向かうべきと考えています。そのことをお伝えしたくて 手紙をお書きしました。なお事故について私自身が書いた本の英訳本 を同封します。お読みいただければ幸いです。

— California’s Governor Newsom and Diablo Canyon

UPDATE: See below

Gavin Newsom may be forced to step down as Governor of California if a recall is approved September 14 by California voters.

He and the Democratic Party leaders are busy branding the recall a Republican effort, including a lawsuit by Newsom and divisive ads with Elizabeth Warren as spokeswoman – “distract and confuse” tactics. Many Californians are not interested in party power games and actually care about officials’ actions, such as when they protect special interests including utility companies and Big Oil, and allow risks or harm to the public and the environment.

For example, in 2016, when Newsom was Lieutenant Governor and on the California Lands Commission. Pacific Gas and Electric applied for a new permit for Diablo Canyon Nuclear Power Plant. The plant had never had state environmental review which many now urged the Commission to require. In addition,

– in 2015, it was revealed that PG&E had used incorrect safety data – since 1982 – and altered its operating license with the help of the Nuclear Regulatory Commission to appear in compliance.

– Mothers for Peace SLO reviewed data and found PG&E committed 29 safety violations in 2014 alone, including inoperable backup generators. Fukushima meltdowns were initiated when the electricity grid shut down and backup generators failed when turned on. PG&E called these violations “gaps in excellence”.

PG&E improperly packed high burn-up spent fuel rods into dry cask storage in 2015, creating a serious risk of a nuclear accident.

– the plant and its desal plant cause extensive damage to the ocean, including its devastating once-through water intake system that kills marine life.

– the plant sits amidst an active, connected network of earthquake faults

– a nuclear accident at Diablo Canyon would impact critical agricultural lands north in Monterey, San Benito, and Santa Cruz Counties, east to the Central Valley, and south to Santa Barbara and Ventura Counties, harm millions of people including Los Angeles, cause environmental destruction on land and to the Pacific Ocean, and devastate California, ranked the 5th largest economy in the world.

These are some of the issues. Friends of the Earth said in March 2015, “Diablo Canyon should never have been constructed in the first place, and now it is clear it should not be allowed to operate another day.”

Further, the Commission hearing was occurring as PG&E was on trial for the San Bruno disaster.

Despite the facts and the dangers from continued plant operation, Gavin Newsom refused to require environmental review and refused to delay the hearing to allow the public and experts to evaluate new information and Commission reports.

Instead, Newsom led the Commission in voting to approve the new permit, and applauded a recent agreement allowing the plant to operate for nine more years.

June 2016 hearing transcript; Diablo Canyon consideration starts on p. 78

Preceding April 2016 hearing transcript; Diablo Canyon starts on p. 55

Newsom’s comments at the hearings were very disturbing, given the issues and risks and PG&E’s safety history.

After 2016, California was hit with the powerful Ridgecrest earthquake and its many strong aftershocks – a powerful reminder of the daily risks. And even a power outage can cause a catastrophic nuclear accident, because nuclear power plants rely on grid power to keep fuel rods and spent fuel pools cool.

Newsom’s critical decision affecting the lives and future of so many is one example of his priorities and judgment. This is the reason many Californians support a recall.
