>Concerns about Diablo Canyon were revived in the wake of the Fukushima disaster, a reactor that was vulnerable due to its location on the coast.<p>That's hardly a valid concern. "<i>The elevation of the Fukushima site is approximately 20 feet [6m] above sea level, while Diablo Canyon sits on a bluff 85 feet [26m] above sea level.</i>" [Wikipedia]<p>Furthermore, people seem to ignore one of the very favorable attributes of Diablo Canyon - it was designed to be paired with a large pumped storage facility, so that power generated overnight is available for peak use during the day.<p>"<i>The Helms Pumped Storage project was designed to be used with the Diablo Canyon Nuclear Power Plant, also owned by PG&E, in the 1970s, when Diablo Canyon was being designed and permitted. It is connected to that power plant by a dedicated high-tension power line.</i>" [Wikipedia]
