n the first days after the earthquake and tsunami of Fukushima Daiichi Nuclear Power Station leaked twice as much radioactivity as previously stated. According to recent calculations of the Japanese nuclear regulatory authority Nisa there are 770 000 Terabcquerel.
The chairman of the Japanese Nuclear Safety Commission, Madarame, told the state television NHK that the accident in Fukushima were due to human error, and acknowledged the same time their own mistakes. The guidelines for nuclear power plants get a case of a prolonged power outage is not available.
He regretted that he did not pay attention to the accident in Fukushima on this deficiency. Madarame, who was due to controversial advice to the Government in the critique says, now that the nuclear experts formed a closed group, which tended to avoid discussion of unpleasant issues. The guidelines would need to change.
Meanwhile, the power plant operators Tepco announced that the hydrogen explosion at Unit 1 of Fukushima Daiichi Nuclear Power Station, on 12 March, the reactor building badly damaged and a strong leakage of radioactivity into the environment led, was due to a design flaw. The engineers at Tepco assume that hydrogen in the discharge of air from the containment of the reactor due to a malfunctioning valve was returned to the reactor.
Many other reactors in Japan are equipped with similar technology for extraction, reported the newspaper Asahi reported on Monday. A review of this system is now necessary. Japanese scientists have called on Monday for more detailed soil analysis at the Fukushima nuclear power plant after off-site power plant not specifically quantified traces of highly toxic plutonium, about 1.7 kilometers were found away from the nuclear power plant.
