Nuclear Rules in Japan Relied on Old Science
Norimitsu Onishi and James Glanz, New York Times
In the country that gave the world the word tsunami, the Japanese nuclear establishment largely disregarded the potentially destructive force of the walls of water. The word did not even appear in government guidelines until 2006, decades after plants — including the Fukushima Daiichi facility that firefighters are still struggling to get under control — began dotting the Japanese coastline.
The lack of attention may help explain how, on an island nation surrounded by clashing tectonic plates that commonly produce tsunamis, the protections were so tragically minuscule compared to the nearly 46-foot tsunami that overwhelmed the Fukushima plant on March 11. Offshore breakwaters, designed to guard against typhoons but not tsunamis, succumbed quickly as a first line of defense. The wave grew three times as tall as the bluff on which the plant had been built.
Japanese government and utility officials have repeatedly said that engineers could never have anticipated the magnitude 9.0 earthquake — by far the largest in Japanese history — that caused the sea bottom to shudder and generated the huge tsunami. Even so, seismologists and tsunami experts say that according to readily available data, an earthquake with a magnitude as low as 7.5 — almost garden variety around the Pacific Rim — could have created a tsunami large enough to top the bluff at Fukushima.
... “We can only work on precedent, and there was no precedent,” said Tsuneo Futami, a former Tokyo Electric nuclear engineer who was the director of Fukushima Daiichi in the late 1990s. “When I headed the plant, the thought of a tsunami never crossed my mind.”

Countering Radiation Fears With Just the Facts
Demose Grady, New York Times
Less than a day later, ominous reports of failed cooling systems and radiation leaks at that plant began to emerge. Dr. Brenner, director of the Center for Radiological Research at Columbia University — the oldest and largest such center in the world — found himself called on repeatedly to explain what was happening with the failed reactors and to assess the radiation risk to public health, both in Japan and around the world.
Dr. Brenner, 57, a native of Liverpool, England, is a physicist who has spent his career studying the effects of radiation on human health. He has published research showing that CT scans increase the cancer risk in children, and he recently testified before Congress, saying that the widespread use of whole-body X-ray scanners at airports would produce 100 extra cases of cancer each year in the United States.
He thinks CT scanners and the people who use them need more regulation to make sure the scans are medically needed and the doses of radiation as low as possible.
... From the start, he has spoken with a scientist’s caution, respect for facts and numbers, and keen appreciation of how much is simply not known or, at this point, even knowable. The situation changes constantly, and the path to the truth can be dicey, twisting through parties with passionate agendas for or against nuclear power, information meted out by government and industry, and public fears of radiation that many scientists consider wildly exaggerated.
How to explain the facts without scaring people needlessly? How to reassure without seeming to sugar-coat or patronize? The last thing people want, Dr. Brenner said, is a guy like him in a white coat on TV smugly telling them everything is fine.
“People are very worried, which is not surprising,” he said. “We want people to be able to make some kind of realistic assessment.”

Nukes and Quakes
Tony Barrell and Rick Tanaka, Rolling Stone
Many of Japan's nuclear plants are dangerously close to seismic fault lines. Only a few protestors, among them a Buddhist monk, are contemplating the aftershock.
---
.... Since the 1950s, uranium has become the core of a long-term plan to make up for Japan's lack of oil.
... The biggest obstacle to this technopolitical fantay [nuclear power in Japan] is the threat from Japan's other endemic primeval force -- the earthquake. About ten per cent of all the energy release by the world's anjual seismic events happens in Japan.
... The nuclear industry in Japan has assumed for years that it should be trusted without question, but as Nakajima says its safety measures are often just "desk-top" and don't allow for more bizarre possibilities. Some plants in Fukui, including those at Oi, are built on the shores of Wakasa Bay and their cooling systems drain into the sea. A tsunami -- the tidal wave caused by a quake -- might suck water out from the pipes causing the core to overheat and explode like a bomb. It hasn't happened yet but nobody can say it couldn't. Also a reactor core and its buildings might withstand a hefty quake, but their all important cooling systems are made from narrow pipes that could rupture. If it isn't shut down fast, a reaqctor without coolant quickly descends into meltdown mode.
Even without the help of another great quake, a whole clutch of reactors built a quarter of a century ago will soon reach their use-by date. They'll have to be "decommissioned", but nobody knows what it costs to dismantle a reactor in Japan because it's never been done. Wishful thinking once again sets the agenda. As a Fukui nuke fan told us: "They're checked out every year, if they get the OK they'll keep on running."
