The operator of Japan’s crippled Fukushima Daichi nuclear plant says it expects to bring the crisis under control by the end of the year.
The operator, Tepco aims to reduce radiation leaks in 3 months and to cool the reactors within 9 months.
The utility said it also plans to cover the reactor building, which was hit by a huge quake and tsunami last month.
About 14 000 people died and another 14 000 are still unaccounted for.
Radiation levels in the sea near reactor 2 rose to 6500 times the legal limit on Friday, up from 1100 times a day earlier, raising fears of fresh radiation leaks.
Meanwhile, the Japanese government had ordered Tepco to come up with a timetable to end the crisis, now rated on a par with the world’s worst nuclear accident, the 1986 Chernobyl disaster.
