Tokyo Electric Power Co. confirmed Friday that the treatment facility to clean highly radioactive water accumulating at the crippled Fukushima No. 1 nuclear plant started full-scale operations at 8 p.m.
Tepco also revealed its updated road map to bring the Fukushima nuclear crisis under control, saying it aims to cool the stricken reactors with a circulating coolant system through processed contaminated water in a month as well as to improve the medical care and mitigate the radiation exposure of its workers.
The latest plan does not appear to deviate from the goals of cooling the reactors and still aims to effect a cold shutdown in which the temperature of the reactor-core coolants is brought below 100 degrees, by mid-January.
