  • Tokyo Electric Power Co. (TEPCO) is working to restart full-scale tests of the water filtration system it will use to decontaminate and recycle radioactive water that has flooded the basements of buildings at the Fukushima Daiichi nuclear energy facility. The system went into full operation on Friday but was shut down after five hours when radiation levels rose more quickly than anticipated in the part of the system that removes oil and sludge. TEPCO may add more equipment to remove oil or lower the water flow rate through the system. Cooling water injections into reactors 1, 2 and 3 are accumulating in the building basements at the rate of 500 tons per day, and could overflow in about a week if the decontamination system is not functional by then.

Concern about the potential for overheating in the pool was a factor in the NRC’s conservative call for U.S. citizens to evacuate as far as 50 miles from the plant, NRC Chairman Gregory Jaczko told a congressional committee yesterday. “We are continuing to review and re-evaluate the 50-mile recommendation,” he said.

WASHINGTON (AP) — Water used to cool radioactive waste at the stricken nuclear complex in Japan did not dry up, as earlier feared, U.S. regulators said Wednesday in a reversal of a claim that pitted U.S. officials against Japan in the days after that country’s nuclear disaster.
