Kyodo reports that 300 tons of radioactive water have leaked from a 1,000 ton tank at the Fukushima Daiichi nuclear power plant. That led Japan’s Nuclear Regulation Authority to consider raising the incident from a Level 1 nuclear event to a Level 3 (a “serious incident” with radioactive exposure 10 times the limit for workers) on the International Nuclear Event Scale, the first time an incident has been serious enough to be reported on the INES scale. The most extreme nuclear events on the scale are considered Level 7, a level only reached by Fukushima in 2011 and Chernobyl.
The latest incident is the worst (at least, so far) of a long list of mishaps this month in the cooling system, from rats chewing through exposed wires causing a blackout of the cooling system to Tepco, the company in charge of the cleanup, failing to stop leaks of contaminated water from flowing into the Pacific Ocean. Earlier this month Japan Prime Minister Shinzo Abe ordered the government to assist Tepco with the cleanup, not that it seems to be helping yet.
Tokyo (CNN) — The operator of the crippled Fukushima nuclear plant has said they need help from outside Japan to stabilize and safely decommission damaged reactors at the facility.
This follows the news that regulators are poised to declare a fresh toxic water leak at Fukushima a level 3 “serious incident,” the gravest warning since the massive 2011 earthquake and tsunami that sent three reactors into meltdown.
