via NHK World / May 14, 2014 / The government and the operator of a damaged Fukushima nuclear plant are expected to start next week releasing into the sea ground water pumped up at the plant.
Officials of the government and Tokyo Electric Power Company say 2 surveys of groundwater show radiation levels of the water are below TEPCO’s safety target, which is lower than the government-set standard, at the Daiichi Nuclear Power Plant.
A study by an outside body, the Japan Chemical Analysis Center, shows 0.039 becquerels of cesium 137 and 230 becquerels of tritium 230 per liter. TEPCO’s analysis shows 0.047 becquerels of cesium 137 and 220 becquerels of tritium 230 per liter.
Officials will explain the findings to the Fukushima prefectural government and fishermen before starting the release of groundwater, probably next Wednesday.
In response to a request by the fishermen, third-party officials will observe the water discharge into the sea.
The government and TEPCO have been preparing for this water bypass operation by pumping up water before it reaches the damaged reactors, where it gets contaminated.
The radiation surveys involved samples from about 600 tons of groundwater that were pumped up last month from 12 wells on a mountainside near the plant.
The utility expects the water bypass operation to reduce the daily buildup of 400 tons of highly radioactive water at the plant by up to 100 tons.
