Fukushima News 2/25/15: Nuclear Waste On Roof of Fukushima Reactor Flowing Directly In Ocean

from missingsky101 No measures taken for radioactive water leak Nuclear & Energy Feb. 24, 2015 – Updated 19:42 UTC-5 The operator of the Fukushima Daiichi nuclear plant did not take any measures to prevent radioactive water that accumulated on the roof of one of the reactor buildings from flowing into the Pacific Ocean. Tokyo Electric Power Company said on Tuesday that rainwater with relatively high levels of radioactive substances has collected on the roof of the No. 2 reactor building. It said the contaminated water may have flowed into a drainage channel whenever it rained and could have spilled into the Pacific Ocean beyond the plant’s port. TEPCO was aware of these rises in the concentration of radioactive substances in the drainage channel as long ago as April last year. But it did not make the information public or take any measures to stop the water from spilling into the ocean. TEPCO has not installed floodgates or equipment in the drainage channel that would warn of rising concentrations of radioactive substances. The utility says there are no radioactive standards for the rainwater it is allowed to discharge into the ocean and it does not plan to install any devices in the channel. The operator says no major changes have been observed in the levels of radioactive substances in nearby seawater. But local residents, including workers in the fishing industry, may react sharply to the news. The drainage channel flows into the sea beyond the port. TEPCO had earlier explained that the contaminated water only affected the port area. TEPCO may reroute wastewater drainage channel Nuclear & Energy Feb. 25, 2015 – Updated 05:29 UTC-5 The operator of the crippled Fukushima Daiichi nuclear power plant is considering a plan to reroute a drainage channel so that contaminated rainwater will not leak outside the facility’s port. Tokyo Electric Power Company said on Tuesday that the water had accumulated on the roof of the plant’s No. 2 reactor building. The firm added that rainwater with relatively high levels of radioactive substances spilled into the Pacific beyond the plant’s port through a drainage channel. Following an outcry by local fishers, the utility said it will consider altering the channel so that water will drain in the port. The firm is also considering a tentative plan to pump up water near the mouth of the channel and release it in the port through another channel. NRA demands TEPCO probe radioactive water leak Nuclear & Energy Feb. 25, 2015 – Updated 02:05 UTC-5 Japan’s nuclear regulator has demanded that the operator of the Fukushima Daiichi nuclear plant thoroughly investigate a recent leak of radioactive drainage water that may have entered the sea. The Nuclear Regulation Authority on Wednesday heard a report on the incident saying levels of beta ray-emitting substances rose sharply in a drainage channel at the plant on Sunday. It also said some of the contaminated water likely spilled into the plant’s port facing the Pacific Ocean. Tokyo Electric Power Company, or TEPCO, has been unable to determine why the radioactivity levels spiked. Authority Chairman Shunichi Tanaka criticized TEPCO for leaving the channel’s gate to the port open for as long as 90 minutes after an alarm went off.
