TOKYO (Reuters) – Following are important developments after a large seism and wave devastated northeast Nihon and game a thermonuclear noesis station, upbringing the risk of anarchical radiation.

* Officials rest committed to cooling downbound overheated thermonuclear render rods and keep spraying setup No.3 at the game Fukushima Daiichi plant. But the plant's operator, Yeddo electric Power Co., says encasing reactors in objective may establish the exclusive artefact to preclude a harmful irradiation leak, the method utilised at Chernobyl in Ukraine in 1986.
