Japan’s nuclear safety watchdog Monday said a leakage of about 1.5 tonnes of low-level radioactive water occurred at a plant ofJapan Atomic Power Co. in the village of Tokai inIbaraki Prefecture. The water was used to decontaminate radiation protection suits and other items and was contaminated to an extent of 33 becquerels per gram, Kyodo News said, adding that the leakage occurred when water was transferred from a storage tank to another tank of a nuclear reactor during decommissioning Wednesday.
The Nuclear and Industrial Safety Agencylaunched an investigation to check whether the water had leaked into the sea, reported Xinhua.
In October 2011 Tatsuya Murakami, the mayor of the village Tokai, said in a meeting with minister Goshi Hosono, that the Tokai Daini reactor situated at 110 kilometer from Tokyo should be decommissioned, because the reactor was more than 30 years old, and the people had lost confidence in the nuclear safety commission of the government.
Seismic research in 2011 showed that the March 11th quake was caused by the simultaneous movement by multiple active faults at the coast of the Pacific Ocean in northern Japan, and on this way a much bigger earthquakes could be triggered, than the plants were planned to withstand, at the time they were built. In February the Tokai Daini Plant in Ibaraki Prefecture and the Tomari power facility in Hokkaido, said that it could not ruled out the possibility that the plant was vulnerable.The nation needs to prepare for powerful quakes and tsunami that have been forecast as having a high probability of striking Tokyo, the Tokai region, the Kii Peninsula and Shikoku in the near future.
In 2011 and 2012, about 100,000 signatures against the resumption of the plant’s operation, halted since last year, were submitted to Ibaraki Gov. Masaru Hashimoto. The petition urges the prefectural government not to allow the Tokai power station to resume operation, saying, “We should not allow a recurrence of the irretrievable sacrifice and loss as experienced in the Fukushima Daiichi nuclear power plant accident”.
