中广网 Beijing on March 12, according to Voice of China "CNR News" reported that after the earthquake in Japan has four nuclear power plants subject to different degrees, a total of 11 nuclear reactors to stop running, which is located in Fukushima nuclear power plant emergency situation , the radiation level inside the central control room up to 1,000 times normal. Administration that nuclear reactors may have radiation exposure. Why does the Japanese nuclear power plant radiation levels rise? This is not cause more accidents? Reporters interviewed a national nuclear power costs Lei Expert Committee, Ministry of Environmental Protection and Nuclear Safety Committee of environmental experts, we connect reporters. Moderator: Tell us about what is now Fukushima nuclear power plant in a specific situation? Reporter: Fukushima nuclear power plant 240 km away from Tokyo, is Japan's largest nuclear power plant. As I said in an interview with Professor Yuzu Sheng Nuclear Power Expert Committee when the Committee of Experts on China's nuclear power, he said all the experts did not break today are in the office closely watching the case of nuclear power plants in Fukushima. He pointed out that the Fukushima nuclear power plant should now be in a relatively stable state. Fukushima nuclear power plant now has two cases, one is a nuclear power plant emergency shutdown after the release of cooling the power supply system of diesel engine group did not start properly, make a further rise of temperature inside the reactor, is said to have reached the normal design value of 1.5 times, this is a very dangerous situation. Another aspect is the Onagawa nuclear power plant in Miyagi Prefecture occurred in the turbine engine room fire, but no radiation leaks. Now the plant in emergency repair maintenance. Moderator: Now run this in the history of nuclear power, the emergency diesel engine can not start, there is no historical precedent. Reporter: Yuzu Sheng pointed out that nuclear power plant in the process of the emergency diesel generator does not start has never happened before, this is the first time, this is a very unexpected situation. Yuzu Sheng also said that from this incident shows, the second generation of nuclear power in the emergency boot mechanism or flawed. He pointed out that the Fukushima nuclear power plant is now up to the second generation unit, second unit needs to start an emergency stop after the emergency diesel generators, nuclear power in the heat exhaust temperature. He pointed out that this is now our second-generation nuclear power plant every week for a diesel engine start exercise, and requires a start in 2 seconds. This time, Japan does not start, he also felt very surprised, because the level of Japan's nuclear power development in the world's leading, and its mechanism is relatively healthy, relatively speaking, but this did not start, is indeed a very unexpected situation . Currently experts are said to Fukushima nuclear power plant emergency call backup power to the temperature of the release of nuclear power reactors. Moderator: The report also mentioned that the nuclear radiation levels inside the central control room rose to a thousand times normal, is this a kind of concept. Reporter: Yuzu Sheng at the outset that the wording of this report is not accurate, because the central control room of nuclear power plants inside if the normal radiation levels rose to a thousand times, people have been killed off long ago. From the Fukushima nuclear power website that is currently in a loop outside the reactor water level of radiation a thousand times more than normal, but still did not leak out. He pointed out that the radiation level is not timely discharged due to temperature, making the outside of the nuclear fuel rods that had a broken layer of packaging, radiation leaks into the reactor in the circulating water, recycled water makes the water value of a loop a thousand times more than normal . Although in a very unexpected situation, but this is not the case is leaking, or manageable. Also learned that
