One word: Fukushima. TEPCO had made the same bland assurances that Edison has been saying about San Onofre right up until the day before the tsunami. To be perfectly frank, it is irrelevant what Edison says about this. The plant is too old and cannot be guaranteed to operate safely. It should be permanently shut down and decommissioned. Period. In no case, should it be allowed to be opened on an expedited basis.
