BS About San Onofre Waste Incident

This sensationalist report compares a recent incident at San Onofre nuclear plant to the accident at Chernobyl:

In a former life, I was chief engineer on a nuclear submarine and a trained senior reactor operator, and I have an MS degree in nuclear waste management. Here is what I think about this "report":

1. By definition, nuclear waste is not "toxic". It is "radioactive". Mixed waste can be both toxic and radioactive. Whoever wrote this report appears to be ignorant of the pertinent terminology.

2. If the waste was ready to transfer to dry storage, all the short term radionuclides had decayed away to a negligible level. To compare this waste to the Chernobyl accident, which released radionuclides from a core which had recently been critical AND was on fire, is absurd. Once again, the author of the report appears to be ignorant of the pertinent facts.

3. If the canister contained spent nuclear fuel, its fuel rods would still have been held inside rigid fuel assemblies, which are metal and have considerable strength. They may or may not have ruptured if the canister had fallen to the ground.

4. It is not clear why the canister would not just have slid down into the transport cask had the ledge given way.

5. It is not clear why Mr. Fritch did not identify this issue immediately to the people on the scene. I have been an independent safety observer for similar evolutions, and had there been immediate safety hazards I would not have waited for a news conference to address them.

Anyway ... that's my two five cents.
