Nuclear Disaster In Japan Could Have Been Mitigated, Say Industry Insiders

Hugh Pickens writes "Some insiders from Japan's tightly knit nuclear industry have stepped forward to say that Tepco and regulators had for years ignored warnings of the possibility of a larger-than-expected tsunami in northeastern Japan, and thus failed to take adequate countermeasures, such as raising wave walls or placing backup generators on higher ground. 'March 11 exposed the true nature of Japan's postwar system, that it is led by bureaucrats who stand on the side of industry, not the people,' says Shigeaki Koga, a former director of industrial policy at the Ministry of Economics, Trade and Industry. Eight years ago, as a member of an influential cabinet office committee on offshore earthquakes in northeastern Japan, Kunihiko Shimazaki, professor emeritus of seismology at the University of Tokyo, warned that Fukushima's coast was vulnerable to tsunamis more than twice as tall as the forecasts of up to 17 feet put forth by regulators and Tepco, but government bureaucrats running the committee moved quickly to exclude his views from debate as too speculative and 'pending further research.' Then in 2008, Tepco's own engineers made three separate sets of calculations that showed Fukushima Daiichi could be hit by tsunamis as high as 50 feet. 'They completely ignored me in order to save Tepco money,' says Shimazaki."

      Actually the nuclear industry was in the fortunate position of being needed by politicians to keep the lights on. Take the UK for example, once world leaders in nuclear technology. Our government paid to develop it all because it was promised to be too cheap to meter if only the initial risky and expensive investments could be made, and plus it was a good way to get weapons grade material and show we had advanced nuclear tech. So during the 50s and 60s we paid for it all and ran the plants, but it turned out they were actually very expensive and not at all easy to build and run.

      In the early 80s all our energy generation was sold off to private companies and turned into a cash-cow for them. All of it except for nuclear, no-one want that because the costs were too high and the risks to big if anything went wrong (and things had gone wrong in the past). The government was offering them fully functional nuclear plants for free and a guaranteed income, but still no-one was interested. In the end we had to subsidise running the plans, insuring them and all the clean-up work when they were decommissioned*.

      So private companies had the government over a barrel. The country needed nuclear and government policy was not to run it ourselves. Now things have changed though and there is little appetite from the voters for nuclear, but lots of demand for green technology. The nuclear lobby is out in force and desperately trying to spin the situation, but people realised that if we just switch the subsidy from nuclear to green then we don't need nuclear any more.

However, such an analysis assumes that the backup generators are all independent systems. As this crisis has demonstrated, the backup generators were NOT independent of each other. Because they were all in the same coast-side, sea level location, they all shared the common vulnerability of being shut down simultaneously by the same tsunami. Therefore, the actual risk of them all failing simultaneously due to a tsunami was equal to the risk of a single one of them failing due to a tsunami.

    The "owners" are the shareholders who were clueless about the risks. Everyone told them everything was just fine. The owners trusted their assets to the "managers" who put their short term interests (profit) ahead of protecting the assets.
    This is how modern capitalism works. The managers (high paid execs) get the profits, everyone else gets the shaft. (Wall street managers did very well before and after the 2008 crash... asset owners... not so well.)
