In a press release entitled "NRC Prioritizes Detailed Earthquake Risk Analysis For Central and Eastern U.S. Reactors," the U.S. Nuclear Regulatory Commission (NRC) has given nuclear utilities an extraordinarily long period of time to upgrade safety in light of the Fukushima nuclear catastrophe.
NRC speaks of having "set a priority list for 21 of 59 nuclear power plant sites in the central and eastern United States to conduct in-depth analyses of the plants’ updated earthquake risk," in recognition that seismic hazards could well be greater than the atomic reactors were originally designed and built to withstand.
And what are NRC's deadlines for the nuclear utilities to take "Fukushima lessons learned" urgent action by? Preliminary analysis, to determine if reinforcements to systems, structures, or components may be needed, is not due till Dec. 31, 2014 -- nearly four years after the Fukushima catastrophe began. If any such upgrades are needed, they need not be installed until Dec. 31, 2016 -- nearly six years post-Fukushima.
Perhaps more astounding, the "detailed," "in-depth risk" analyses described in the press release headline are not due until June 30, 2017 (over six years post-Fukushima) for 10 "priority" sites, and not till June 30, 2019 (more than eight years post-Fukushima) for another 11 "priority" sites.
At another 23 sites, NRC is still yet to decide whether or not they need to do the "in-depth risk analysis." If NRC decides they do, they have until Dec. 31, 2020 (almost a decade post-Fukushima) to get it done.
Apparently, we must simply hope earthquakes stronger than originally designed and constructed against many decades ago won't strike before NRC requires these actions to be taken.
