Radiation Leak at Fukushima Nuclear Plant Confirmed

Radiation Leak at Fukushima Nuclear Plant Confirmed

Japan’s radiation leak: Shades of Three Mile Island and Chernobyl? (The Christian Science Monitor)

Japan’s unfolding nuclear power crisis remains at an unstable, volatile stage, warn US nuclear experts who, while hopeful, say past nuclear accidents – at Three Mile Island and Chernobyl – grew far worse over several days before being controlled.

Their comments, which came during a Saturday conference call convened by anti-nuclear power groups, were in sharp contrast with reports by the Japanese government which appeared to indicate the main crisis in one of its nuclear reactors was past, although a state of emergency remained in effect for five reactors.

Japanese soldiers were reported pumping seawater into the #1 reactor at the Fukushima I power plant 150 miles north of Tokyo to keep it cool. But one US expert characterized the move as an apparent last-ditch “Hail Mary” effort that could easily fail and be followed by a major radioactive release.

An enormous explosion Saturday morning – possibly due to a buildup of hydrogen gas – destroyed most of a secondary containment building housing the #1 reactor, but was reported by a government spokesman not to have breached a critical inner steel liner – the reactor’s primary containment vessel.

On Saturday, the Japanese government reported five reactors at two different nuclear power plants – Fukushima I and Fukushima II – to be in a state of emergency following the massive earthquake that hit Japan Friday. A total of 11 of the nation’s 54 reactors shut down following the quake – knocking out about 30 percent of the nation’s power. Still, Japanese officials were matter of fact.

Chief cabinet secretary Yukio Edano told reporters Saturday that radiation around the plant had started to decrease. A “tiny” amount of radiation had leaked earlier in the day when officials attempted to relieve pressure inside the reactor.

“We have confirmed that the walls of this building were what exploded, and not the reactor’s container,” Edano said, adding, “There was no large amount of radiation leakage outside. At this point, there has been no major change to the level of radiation leakage outside, so we’d like everyone to respond calmly.”
