"The operator of the wrecked Fukushima nuclear plant said it had found another leak of contaminated water on Wednesday, piling pressure on the utility to curb the problem as it seeks permission to release water to the sea."
"The Fukushima Daiichi Nuclear Power plant was hit by a 9.0 magnitude earthquake and tsunami more than two years ago, triggering nuclear reactor meltdowns and explosions.
Tokyo Electric Power, or Tepco, said a worker patrolling the area spotted the leak just after noon, with droplets of contaminated water leaking out between the tank's circular steel structure.
Shunichi Tanaka, chief of Japan's new nuclear regulator, set up after its predecessor was discredited in the 2011 disaster, told a news conference that Tepco should deal with the problem immediately. But he said the regulator did not regard the matter as serious."
