Stranded Spent Nuclear Fuel with Nowhere to Go – A Clear & Present Threat to National Security
A string of pellets cased in the zircalloy cladding is called a fuel rod. Source
It is usually 4-5 meters long. Each rod contains 350-400 pellets. Source

A human being standing close to an unshielded hot fuel rod would receive a lethal dose of radiation in just minutes. Source
Ten years after removal of spent fuel from a reactor, the radiation dose 1 meter away from a typical spent fuel assembly exceeds 20,000 rems per hour. A dose of 5,000 rems would be expected to cause immediate incapacitation and death within one week. Source
Each fuel assembly contains 179-264 rods. Source
Holtec canisters each contain 37 fuel assemblies.

Each canister contains more highly radioactive Cesium-137 than was released from Chernobyl. Source
Even a microscopic through-wall crack will release millions of curies of radiation into the environment states Dr. Kris Singh, President and CEO of Holtec. Source
The San Onofre ISFSI houses 73 vertical Holtec canisters. Source
Another 50 Areva NUHOM canisters sit in a separate, horizontal dry storage facility nearby on-site. Source
These containers do not have NRC approval for transport.
In any case, the U.S. Nuclear Waste Technical Review Board reports that this spent fuel will not be cool enough to move until the year 2100.
These canisters have a manufacturer’s ‘guarantee’ for only20 years.
Some canisters like these have been shown to fail in less than 20 years. Source
Some of the horizontal canisters at San Onofre are already 20 years old. Source
No Federal central repository for high level radioactive waste now exists, nor is likely to any time soon.
About 88,000 metric tons of spent nuclear fuel from commercial reactors remain stranded at reactor sites, and this number is increasing by some 2,000 metric tons each year. These 77 sites are in 35 states and threaten to become de facto permanent disposal facilities. A proposed new generation of SMRs will produce even more, more toxic forms of waste. Source
