Tokyo. .- Japan's nuclear agency ruled out that the explosion this morning at a Fukushima nuclear plant damaged the structure of the reactor protection, sources of the organization's official news agency Kyodo. "Any damage to the protection of the reactor is highly unlikely," he was quoted as saying.
However, as a new preventive measure, the evacuation area for the two nuclear plants in Fukushima has been extended to 20 kilometers after the explosion this morning at a power plant, according to state broadcaster NHK. The experts consulted believe that the damage could be minimal if the blast did not open the interior of reactor.
"Despite the exterior damage to the actual structure, while the steel shell remains intact, most of the radiation will be contained," the expert told Reuters in Physics from Imperial College London, Robin Grimes. The explosion in one of two plants in Fukushima took place during one of the aftershocks of yesterday, at a time when operators were releasing excess pressure on the valves after the failure of all cooling generators.
The Japan Government has recognized that the radiation at the site has increased - even think it could be released within an hour of radiation a person is able to resist in a year, according to NHK - but has yet to examine the real danger of detonation. "It's just that that's the problem: we do not know what is happening inside the plant," he told Sky News the expert from the Carnegie Research Center, Mark Hibbs.
Professor of Nuclear Physics of the University of Surrey (United Kingdom), Paddy Regan, also believes that the explosion did not affect the protection of steel. "It's what contains all the nuclear fuel, and if broke ... well, that's what happened in Chernobyl," said Regan, with respect to the catastrophe of the 1986 nuclear plant in Ukraine.
Other views of experts also downplay the explosion. According to the World Nuclear Association, the explosion would be due to sudden heating hydrogen gas released, which in theory would not lead to any increase in radiation, told Reuters spokesman Ian Hore-Lacy. "With the explosion, the hydrogen disappears and there is nothing to fear," he told Reuters.
