Decommissioning the San Onofre Nuclear Generating Station\u2019s units 2 and 3 could begin by the end of this year, according to the Nuclear Regulatory Commission. Southern California Edison, though, isn\u2019t expecting to commence \u201cmajor dismantlement\u201d work until 2016, according to utility spokesperson Maureen Brown. The federal agency held a meeting in Carlsbad for public feedback on Edison\u2019s proposed \u201cpost-shutdown decommissioning\u201d activities Oct. 27. The agency noted it has former experience in decommissioning. That includes the 1,130 MW Trojan plant in Oregon, shut down in 1992, and the 1,000 MW San Onofre unit 1 reactor\u2014although the latter reactor\u2019s vessel remains on site after numerous attempts to ship it to storage facilities. Decommissioning units 2 and 3 is expected to cost $4.4 billion. Ratepayers in California have been paying into a trust fund for the eventual burial. Edison officials claim that there is enough money in the trust to carry out decommissioning, with nuclear waste stored in temporary dry casks on site.
