Japan Nuclear Operator Conducts Check on Risky Unit

[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.
Tepco [...] only conducted this week’s tests because of widespread concerns voiced over the structure’s safety, he added.
Tepco says that, although it hasn’t analyzed the chances of an accident destroying or cracking the pool, it has made some preparations all the same. Because the fuel rods have been cooling for more than a year, even if the water-circulation system shuts off it should take about three weeks for the heat from the rods to boil off enough water that radiation starteds leaking out, Tepco estimates.
