CPUC Comes Under Scrutiny For Ineffective Financial Management

The agency that is holding a public hearing this afternoon on the San Onofre nuclear power plant is itself coming under scrutiny from the state’s nonpartisan Legislative Analyst .

We have gone from being told about a tiny (radioactive) leak at SanO over a year ago to now being stuck with a 1.3 Billion Dollar Debacle that SoCal ratepayers are still paying for at over 54 Million Dollars a month, with no end in sight!

Even the NRC and now subsets within the NRC like the NRR and others are still trying to understand exactly what happened to cause the damage which destroyed Unit 3's NEW steam generators in less than a year so that they can better evaluate the damage already done to Unit 2 steam generators.

Edison is desperate to restart using they're poorly in-house designed steam generators at any power level so that they can claim that all this is just "part of doing business" and that the ratepayers should pay for this debacle instead of Edison's shareholders who have had record profits the last few years while SoCal ratepayers have seen their electric bills move ever upward!

How bad does it has to get, before SoCal ratepayers can expect to get a fair and unbiased investigation into why all the checks and balances set up to protect CA ratepayers HAVE COMPLETELY FAILED TO WORK?

It is past time for this ENERGY RIP OFF to end, San Onofre should be taken off the rate base immediately and a full unbiased investigation begun with public access to all relevant documentation going back to the original "up-rate" decision that set the stage for doing the replacement steam generator program in the first place.

Until a REAL California LEADER steps forward and DEMANDS OPENNESS, SoCal ratepayers will continue to be subject to continued "energy enslavement" thanks to the too cozy relationship between the Utility and those that regulate them which has enabled thIS debacle to continue despite numerous attempts to sweep it under the rug and/or away from public scrutiny!

Now is the time for our Public Servants to step forward and actually perform their sworn duty by SERVING THE PUBLIC and do what is best for the ratepayers not JUST Edison's shareholders, even at the risk of some of them losing their Nuclear Payback*.


Those that support nuclear power because nuclear power somehow supports them; no matter what the health implications or other "costs" are for others.

To help readers learn more about how Steam Generators (SG) can “fail”, here is a link to an amazing accurate animation that was done to illustrate San Onofre’s Replacement Steam Generators (RSG) problems (which included MULTIPLE SG tube failures) and the animation even illustrates a Main Steam Line Break (MSLB):
Note: By scrolling over the animation a large number of additional animations can be viewed!

At San Onofre, it was one SG tube (as far as we know) that started to leak that caused their shutdown because what was leaking was radioactive core coolant which was first only monitored but then started increasing in volume so fast that Edison had no choice but to shut the reactor down.
Later upon further inspection and testing, not one but 8 tubes failed in-situ testing (done in place under controlled conditions) which is something that has never happened before in the history of the entire US Nuclear “fleet”. Even the NRC called that a serious safety concern and they are still trying completely understand how that occurred. It is also is import to note that during this same period after Jan. 31, 2012, Unit 2 was also shutdown (for refueling). When they inspected its SG’s, one of its tubes had 90% wall wear which is well above the 35% safety standard and Edison did not even know it!

More on that here: Nuclear Power Plant Basics

Important Note: The steam generator’s tubing wall thickness is thinner than a dime (0.043 inches) to help transfer heat, but it also serves as a vitally important boundary between the radioactive coolant circulating inside the tubing which must remain separated from the non-radioactive water/steam mixture which circulates outside the tubing. A leak, crack or worse, a complete failure of one or more of any of the tubes inside the steam generator would allow highly radioactive coolant to mix directly into the non-radioactive water/steam mixture which would then escape into the environment. Additionally, should a Main Steam Line Break or other similar problems occur, the rapid loss of core coolant that is needed to constantly cool the radioactive fuel rods in the reactor could lead to a catastrophic meltdown of the entire radioactive reactor core.


This MSLB event is also mentioned in previous ACRS reports (Response to NRR RAI -32 – Technical, page 49).
