Re: “Utilities commission rejects Diablo's community settlement

A two-year old Diablo Canyon nuclear waste stainless steel canister has all the conditions for cracking and PG&E has no plan in place to deal with cracking or leaking canisters. The NRC said once cracks start, they will grow through the wall in about 16 years. PG&E continues to use these thin-wall (1/2" thick) canisters, each filled with about a Chernobyl disaster's worth of lethal radionuclides (Cesium-137).

The rest of the world uses proven thick wall metal casks (10" to 19.75" thick) that don't crack and can be inspected (inside and out), that can be maintained,repaired and monitored to PREVENT leaks. The NRC refuses to require those basic safety requirements that we expect in a car.

The legislature at both the state and federal level should consider these issues before allowing any more ratepayer money to be spent on thin-wall dry storage containers.

The CPUC, CEC, Coastal Commission, and NRC are aware of these problems, but refuse to address them. PG&E and Southern California Edison cannot be trusted to protect our safety or financial future. The state legislature should call an emergency session to address this. They should base decisions on evidence and not unsubstantiated statements from nuclear industry supporters or even independent "experts". See evidence at

Time is of the essence. California Chernobyl cans have been loading since 2001 at Rancho Seco, since 2003 at San Onofre, and 2006 at Diablo Canyon. See DOE inventory report of U.S. spent nuclear fuel dry storage, with dates first loaded, at

Re: “A warning from Houston

Even shelter in place won't work. And we won't know where the plumes are as the winds change.

Another major risk are the thin-wall steel dry storage canisters. A two-year old Diablo Canyon canister has all the conditions for cracking. Each canister contains about as much highly radioactive Cesium-137 as was released from the Chernobyl nuclear disaster.

PG&E has no technology to inspect for cracks in these Chernobyl cans, and no way to repair, maintain or monitor to PREVENT leaks. What's even worse,
they have no safe plan in place to deal with leaking canisters. The Nuclear Regulatory Commission states once a crack starts it will grow through the wall in about 16 years.

All the waste that's ever been generated is sitting at Diablo Canyon.

The waste has already been mismanaged. Over half the fuel waste was loaded incorrectly in the canisters. This can cause the fuel and fuel rods (referred to as cladding) to become damaged. With the high burnup fuel used at Diablo, hydrogen and other explosive gases can build up in the canisters. Mixed with oxygen there is a potential for explosions. How many Chernobly cans can we afford to have leak and potentially explode?

Residents need to advocate for thick-wall casks that don't have the problems of the thin-wall canisters. This is the standard in most of the world. Diablo cans are 1/2" thick. European ones are 10" to 19 3/4" thick). This is just common sense.
