Japan’s top nuclear regulator has raised safety concerns about hastily built storage tanks and their foundations after signs of more leaks of radiation-contaminated water at the Fukushima Dai-Ichi nuclear power plant.

Japan’s top nuclear regulator has raised safety concerns about hastily built storage tanks and their foundations amid reports of new leaks of radiation-contaminated water at a tsunami-hit nuclear plant.

Japan’s nuclear regulator has upgraded the rating of a leak of radiation-contaminated water at its tsunami-hit nuclear plant to a “serious incident” on an international scale.

A leak of highly radioactive water at the crippled Fukushima nuclear power plant could be the beginning of a new disaster, Japan’s nuclear watchdog said.

The Japanese nuclear watchdog said it is taking the leakage of highly radioactive water at the crippled Fukushima nuclear power plant seriously.

Contaminated water with dangerously high levels of radiation is leaking from a storage tank at Japan’s crippled Fukushima nuclear plant, the most serious setback to the clean-up of the worst nuclear accident since Chernobyl.

Japan is moving a step closer to restarting nuclear reactors as utilities file for safety inspections at their idled plants.

A seismic fault running underneath a nuclear plant in western Japan is likely to be active, which could force the scrapping of one of its two reactors, according to a team of geologists.

Japan has launched a new nuclear oversight agency following criticism that collusion between regulators and plant operators contributed to meltdowns at the tsunami-stricken Fukushima Dai-Ichi plant.
