Workers began to see some success in their battle to cool down reactors at the quake-damaged Fukushima Daiichi nuclear plant Sunday, but Japanese officials said they may need to release additional radioactive gas into the air.
The plant's owner, Tokyo Electric Power Co., said electricity was being supplied to reactor No. 2 , Kyodo News reported. But officials said they were monitoring reactor No. 3 to determine whether to release gas to reduce mounting pressure in the containment vessel -- the steel and concrete shell that insulates radioactive material inside.
Power company officials said pressure was higher than previous readings -- but stable -- Sunday afternoon. And Chief Cabinet Secretary Yukio Edano said the pressure increase did not require "an immediate release of the air at this moment."
Workers have let out radioactive steam to release pressure inside affected reactors in previous operations.
