TOKYO, March 15 The operator of Japan's earthquake-stricken nuclear power plant may pour water by helicopter to cool a spent-fuel pool in a reactor within two or three days, the plant operator said.
Tokyo Electric Power Co may pour the water in the building housing the No.4 reactor at the Fukushima Daiichi nuclear plant, a company official told a news conference.
A blast earlier punctured two holes in the wall of the outer building of the reactor, exposing the nuclear spent fuel pool to the outside air.
Japan is facing a potential catastrophe after cooling problems and explosions at the Fukushima plant, which released low levels of radiation that the wind could carry to Tokyo.
