Kyodo news reports:
Tokyo Electric Power Co. on Monday took the unprecedented measure of dumping 10,000 tons of low-level radioactive water in the Pacific Ocean from a facility at its crippled Fukushima Daiichi nuclear power complex to make room for the storage of more highly contaminated water, which is hampering restoration work at the plant.
***Nishiyama also said that it had become necessary to release 1,500 tons of groundwater, also containing radioactive materials, found near the Nos. 5 and 6 reactor turbine buildings out of concern that the water could drown safety-related equipment.
Of course, the government said there was "no major health risk", even though:
The level of radioactive substances in the water is up to 500 times the legal limit permitted for release in the environment.
