TOKYO (AP) - Experts fear that a massive underground reservoir of contaminated water that has slowly spread beneath the crippled Fukushima nuclear power plant is close to reaching the Pacific Ocean.
The problem highlights what is fast becoming a new crisis at the plant two-and-a-half years after the meltdowns at the Fukushima Dai-ichi plant: the inability to contain vast amounts of radioactive water.
The looming crisis is potentially much bigger than the discovery earlier this week of a leak from a tank used to store contaminated water used to cool the reactor cores.
