The operator of Japan's Fukushima nuclear plant is considering installing underground walls around its crippled reactors to prevent radioactive water seeping out, according to a broadcaster.
Tokyo Electric Power Company (TEPCO) is studying the measure to contain contaminated water leaking from the plant's reactors which were damaged in the March 11 earthquake and tsunami, TV Asahi said on Saturday, citing unnamed sources.
Workers would have to dig to a depth of 15 metres (50 feet) to reach an impervious layer to build the walls on, it said.
TEPCO has dumped a massive amount of water into reactor containers and overheating pools containing spent nuclear fuel rods, after the magnitude 9.0 quake triggered monster waves which knocked out the plant's cooling systems.
Workers battling to stabilise the battered nuclear facility later found highly contaminated water submerging turbine buildings and underground tunnels, with some running off from a cracked concrete pit into the Pacific Ocean.
