[Tepco] said it took extra steps this week to check the soundness of one of its riskiest reactor buildings, in response to growing public unease over the possibility of further accidents at the facility.
The investigation—the first of its kind to take place at Fukushima Daiichi since three reactors spun out of control 14 months ago—also underscores how unclear conditions at the plant remain, and how deep the distrust in Japan’s nuclear industry runs.
even some who think there is little chance of the pool collapsing say the fuel rods should be transferred to a safer place as soon as possible. “It’s a race against time,” said Hajimu Yamana, a professor of nuclear engineering at Kyoto University, who heads a government committee on decommissioning the plant.
Tepco says it is pushing to start the removal process by the end of next year.
