The Tepco speaker was blaming it on the fact that the panel installation is a temporary one (still? after 2 years?) therefore it is harder to control the environment it operates in (did it rain on it or something?).<br />Also, Fuku 1 receives electricity through multiple lines but reportedly the distribution panel is a single point of failure.<br />Really this is "same old" nuclear security: in theory it is safe but in practice there are too many close calls and too many major disasters (once every 25 years is way too much).<br />On the other hand, when skipping maintenance is a common practice, the gap between theoretical safety and practical results is hardly surprising.<br />Remember that upon April 2011 earthquake a npp in Tohoku (Higashidori?) had to use its emergency generators but one of them failed because they installed some gaskets the other way around? Apart from shoddy work, do they ever *test* safety equipment?<br />Especially right after March 2011 earthquake you'd think they would double check at least the emergency generators but no.<br />Beppe<br /><br />BeppeAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-48458639758381955122013-03-19T13:10:28.506-07:002013-03-19T13:10:28.506-07:00Well, it's only partial redundancy.
