The amount of highly radioactive water on the premises of the Fukushima No. 1 nuclear power plant decreased 320 tons during the latest seven-day period, Tokyo Electric Power Co. said Aug. 24.
The amount of highly radioactive water on the premises of the Fukushima No. 1 nuclear power plant decreased 320 tons during the latest seven-day period, Tokyo Electric Power Co. said Aug. 24.
The new purifying unit, called "Sarry," which is short for Simplified Active Water Retrieve and Recovery System, began operations Aug. 18 and added to the overall treatment capacity. The amount of radioactive water only decreased slightly, though, because the treatment plant had to be suspended temporarily for trial runs.
TEPCO said the hourly treatment capacity increased from 45 tons to 70 tons. Radioactive water stored in buildings and that was transferred from the buildings to the central waste treatment plant totaled 118,410 tons, down 320 tons from a week earlier. A total 6,780 tons of radioactive water was treated between Aug. 17-23, setting the utilization rate at 80.7 percent of designed capacity.
TEPCO projects that the radioactive water in the basement of the turbine buildings at the No. 2 and No. 3 reactors will decrease to target water levels in mid- or late September.
