Typhoon Roke brought evacuation orders and fears of floods to Nagoya city in central Japan today as it approached the main island of Honshu on a course toward the crippled Fukushima Dai-Ichi nuclear plant.
Roke, due in Fukushima prefecture in 48 hours, may hinder work to control leakage of water into the basements of the Dai- Ichi reactor buildings, which contained 102 million liters of radioactive water as of Sept. 13, according to Tokyo Electric estimates.
The storm may drop 150 millimeters of rain on Fukushima within 24 hours, likely in short, heavy downpours, Okada of the Japan Meteorological Agency said by phone today.
Since July, much of Tokyo Electric’s work in Fukushima has focused on decontaminating highly radiated cooling water that ran off into basements and trenches at the damaged reactors.
In addition, as much as 500 tons, or 500,000 liters, of underground water is leaking into Dai-Ichi buildings every day through cracks in walls and trenches, Tokyo Electric spokesman Hajime Motojuku said today.
The company is in the process of installing a cover for the No. 1 reactor building and aims to put similar covers over units 3 and 4 next year after debris is cleared, Tokyo Electric spokesman Takeo Iwamoto said today. The tops of those three units were blown off by hydrogen explosions in March.
Still, the covers are unlikely to prevent rainwater from flowing into the basements, Iwamoto said.
