Tepco’s Plan Said to Extend Nuclear-Leak Risk Through June

Tokyo Electric Power Co. estimates the fight to stabilize its crippled Fukushima reactors will last through June, leaving them vulnerable to more aftershocks and radiation leaks, a person briefed on the utility’s plan said.

Engineers at Tokyo Electric rejected a proposal to flood reactors at the damaged plant, which could lower temperatures in days rather than months, according to the person, who asked not to be identified because he isn’t authorized to speak to the media. Instead, the utility is pumping in water and venting off steam, a method called “feed and bleed.”
