Articles for SCE/CEP members, dry casks problems

This will be a on going list of information on nuclear waste storage and dry casks. The below articles need to be read and understood by all concerned citizens and SCE/CEP members.

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice (IN) to inform addressees of recent operating experience on environmental moisture causing premature degradation of structures and components important to safety during spent nuclear fuel storage operations.

See the map showing the location of existing independent spent fuel storage installations (ML13057A527). A important reference for us to be aware of.

The NRC has no experience in transferring failed (damaged) fuel from one cask to another and no procedures for doing this. In fact, no spent fuel bundle, damaged or not, has ever been transferred from one dry cask to another. Since high burnup fuel is more likely to fail sooner in storage, this becomes an even bigger and more urgent problem. And the failure could result in a breach of the cask, exposing radiation to the environment.

The Department of Energy (DOE) states fuel burnup as low as 30 GWd/MTU shows signs of cladding degradation. All current San Onofre dry casks have high burnup fuel assemblies over 30 GWd/MTU. San Onofre also has 95 failed spent fuel bundles stored in 15 dry casks.

The Nuclear Regulatory Commission (NRC) may require the waste to be stored at current sites for hundreds of years, since there is no permanent storage solution.
