Tepco Slows Water Injection at Reactor to Curb Risk of Explosion

Tokyo Electric Power Co. slowed the pace of water injection into one of the six reactors at its crippled Fukushima Dai-Ichi nuclear station after a drop in pressure and temperature increased the risk of an explosion.

“We wouldn’t want the pressure of the containment vessel to fall below that of the atmosphere,” Junichi Matsumoto, a general manager at the company known as Tepco, said at a media briefing in Tokyo today. The water flow was reduced to 6 cubic meters an hour today from 10 cubic meters, and nitrogen is also being injected to help avoid a hydrogen explosion, he said.
