Even if this is true, it’s either too much of a coincidence or they’re too optimistic.
Last night on NHK it was announced that Tokyo Electric Power Company (TEPCO), the owners and operators of the troubled Fukushima Daichi Nuclear Power Plants, had on 7th March 2011 submitted their first ever revisions to tsunami estimates to the appropriate government office. The same office that has been publicly accused of failing to fulfil their oversight safety duties of nuclear power plants. TEPCO admits that the Fukushima plants were designed to withstand a 5.7m wave (tidal, storm surge, or tsunami), but last year a revision to this estimate suggested that they should prepare for a 10 meter wave, so they claim to have submitted this revision four days before the Tohuku earthquake and tsunami struck. Thus, it is possible that both the government and TEPCO had not neglected their duties, just unfortunate timing… very suspicious to me.
Secondly, a German documentary was aired in Japan, which was about how a German contractor is dismantling the Russian unwanted nuclear powered submarines leftover from the cold war. Interestingly, the company had no immediate plans on dismantling the some 300 nuclear reactors, instead pulling apart the submarines, cleaning off any radioactive material, and selling the metal to scrap. The reactors are being stored in a sarcophagus (their own hulls with some extra lining added), and will be left for 100 years to when it is hoped that the next generation of nuclear-reactor disposal experts will know what to do. The reactor cores will still be dangerous, but less dangerous. In contrast, the Japanese government and TEPCO seem confident that they can solve the Fukushima problem in only a few decades. It should also be pointed out that the reactors are far bigger than a submarine reactor core. They seem very optimistic.
