San Onofre Nuclear Generating Station Unit 1 Decommissioning Funding Status Report Provided below is the information required by 10 CFR 50.75(f)(1) for San Onofre Unit 1.
This information is reported every year for San Onofre Unit 1 because it was permanently shut down before the end of its licensed life and is currently being decommissioned.
All dollar amounts are in 2010 dollars, and the owners are reported as follows:
Southern California Edison (SCE) 80 %
San Diego Gas & Electric (SDG&E) 20 %
- 1) The decommissioning fund estimated to be required pursuant to 10 CFR 50.75(b) and (c) is the following:
a) The minimum amount calculated by the method prescribed by 10 CFR 50.75(c) is $389.6 million.
b) The San Onofre Unit 1 site-specific estimate (1) for decommissioning includes the following radiological decommissioning costs associated with terminating the site license:
San Onofre Unit 1 Estimate of Radiological Costs $ 567.4 million Actual Radiological Costs through 12/31/2010 $ 473.8 million To Go Costs $ 93.7 million The To Go Costs reflect the remaining obligation for the radiological costs associated with terminating the site license.
- 2) The Decommissioning Trust Fund amount remaining at the end of calendar year 2010 (net of estimated capital gains taxes) is:
Owner San Onofre Unit 1 SCE $ 168.8 million SDG&E (2)
