One of the leading German experts in nuclear accidents has described as "hopeless task" the attempt to stop the merger of the reactors at Fukushima and believes that the Japanese effort is "overwhelmed". Things to do, he says, is to evacuate. Evacuate fast 50 kilometers or more, and seal the reactors as in Chernobyl.
"The merger, not one but probably two reactors, there was a long time, and a reporting error is important," says Edmund Lengfeld, director and founder of the Radiological Institute "Otto Hug" in Munich. This expert these days being a common source of German television, which attempts to explain in an understandable way what is happening in Japan.
"The merger took place long ago. It is clear from the emission of radionuclides. Once you have trig, cooling is not possible and the merger will continue for a long time," says Lengfeld told the public radio Deutschlandfunk. Efforts to halt the merger cooling the reactor, first with sea water and then with fresh water, are "useless task." "Only serve to expose people to send there.
They are trying to stop something that can not be stopped. Instead, what seems urgent evacuation of people within a radius of 50 kilometers or more," he says. The water is of little use, he says. Even the use of boron and lead throw sand on the reactors, as in Chernobyl, it seems "marginal." The most important thing to avoid is, "exposing people to radiation, and this is achieved by evacuating," he insists.
Radiological Institute in Munich was created as a result of the Chernobyl accident (April 1986), which Lengfeld, decorated in Belarus and honorary professor at the University of Minsk, was heavily involved. Asked whether to exit the reactor accident to their fate, Lemgfelder explains that "the merger of the reactor just coming to a standstill, when the molten metal fuel rods and coverings, mixed with sand, soil materials concrete substrate and the reactor building, become an amalgam cools past years.
" Regarding the duration of radioactive emissions, the expert believes it will continue until the facilities are covered. "The problem will remain there while he or reactors are not covered by a sarcophagus, as in Chernobyl, or a mountain of sand. Until then there will still escape in the form of radioactive gases that are favored by the steam generated by shedding water.
And while the release of gases do not stop, there will be a greater release of radioactivity and exposure to the population, "he warns. At present, the consequences for the environment "are secondary," he says. "First we need to protect people, then we need to see the magnitude and extent of damage, what territory will be closed, etc.
Like Chernobyl, we must define a broad zone, "he predicts. Regarding the assessment of the performance of the Japanese authorities, Lemgfelder is very critical." In contrast, the Soviets acted more consistently, because much faster evacuated a wide area. "crisis management has not been good and trustworthy" he adds.
"Of course, the Japanese have the additional problem that the density of population there is twenty times higher than in Chernobyl. They also have the destruction of infrastructure caused by the earthquake, and this is a challenge that goes beyond even a technologically highly developed country like Japan, "he says.
