About 12 cubic meters of waste water containing highly radioactive substances was found leaking from the pipe of a desalination device at the crippled Fukushima No. 1 Nuclear Power Plant in the early hours of April 5, Tokyo Electric Power Co. (TEPCO) announced.
The level of radiation in the water, which contained radioactive substances such as strontium, is believed to top 100,000 becquerels per cubic centimeter. There is a possibility that the contaminated water flowed into the ocean through a draining trench, said TEPCO, the operator of the troubled nuclear power station.
According to TEPCO, the flow of waste water in the pipe increased at around 1:05 a.m. on April 5. A TEPCO employee found the water leaking at 1:50 a.m. The water stopped leaking at around 2:20 a.m. after the valve to the pipe was shut off.
On March 26, water leaked from the pipe of the desalination apparatus, and about 0.08 cubic meters of contaminated water was released into the ocean.
