Stranded Spent Nuclear Fuel with Nowhere to Go – A Clear & Present Threat to National Security

A string of pellets cased in the zirconium 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 51 Areva NUHOMS canisters sit in a separate, horizontal dry storage facility nearby on-site, with 13 more in the process of being added. Source

These containers do not meet the Nuclear Waste Policy Act or NRC safety requirements for monitored, retrievable fuel storage or transport.

In any case, a U.S. Nuclear Waste Technical Review Board report suggests that this spent fuel may not be cool enough to meet transportation rules to move until the year 2100. [See pgs. 76 & 77]

These canisters are licensed for 20 years, but have no manufacturer’s warranty.

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 be approved and constructed 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
