Nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive.Even small nuclear devices can devastate a city. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major aspect of international policy since their debut.

March 12, Japan's Jiji news agency quoted the sources said Tokyo Electric Power Company, the first nuclear power plant in Fukushima Prefecture Unit 1 15:06 after the explosion released a large number of major secondary disasters caused by nuclear radiation. Japanese nuclear power plant is proposed to be quickly evacuated nearby residents, do not eat or drink anything in the evacuation process, try not to let the skin exposed. To a safe venue to be replaced after the clothing. Evacuation area should be expanded, if not immediately evacuated, the residents should be reminded to close the doors and windows, turn off air conditioning.

Nuclear Safety METI announced 12 security hospital, Fukushima No. 1 nuclear power plant unit around the first detection of cesium and radioactive iodine, cesium and iodine are the core of the fuel product of uranium fission occurs, which indicates that the reactor core fuel melt further. However, the Unit 1 reactor vessel steam has been released, the air pressure inside the container has begun to decline.

Nuclear Safety Security Court officials told a press conference the day: \"that the fuel is molten core.\" Concrete core temperature is currently not clear, but the design that can resist high temperature of 1200 has been melting fuel cladding. This shows that since the quake automatically shut down nuclear reactor after about 1 day since the continued proliferation of radioactive materials, nuclear power plant accident has reached a very serious condition.

Affected by the 11 earthquake, the first nuclear power plant in Fukushima leakage of radioactive material occurred, followed by Unit 1 of hydrogen explosion

occurred. Japanese government to the first nuclear power plant in Fukushima from the original scope of the evacuation is raised to a radius of 10 km radius of 20 km, near the evacuation of the second nuclear power plant enhance the range from 3 km to 10 km. International Atomic Energy Agency said that Japan is transferred from the 17 million people in the vicinity of two nuclear power plants.

March 12, Japan ShiShiShe quoted Tokyo electric power company news FuDaoXian first nuclear power plant, said Japan unit 1 6 minutes after the explosion when 15 math-model caused significant release of a large secondary disasters. The Japanese authorities suggest nuclear power station nearby residents should leave quickly, not in evacuation process take any thing, try not to let the skin exposed. After the security site should change clothes. Should expand evacuation area, such as not immediately evacuated, should remind residents closed doors and Windows, shut off the air conditioning.

Japan's trade ministry atomic energy security guards courtyard 12 announced that f island first nuclear power plant unit 1 peripheral detected radioactive substances, cesium and iodine cesium and iodine is the fuel the reactor core product of uranium fission occurred, suggesting that the reactor core fuel melting further intensifies. However, 1st unit within the reactor vessel has been released, the steam tank air pressure has begun to decline.

Atomic energy security guards court officials on the day of the press

conference said: \"can think of the reactor core fuel is melting.\" At present the reactor core concrete temperature is not clear, but the design can be able to bear or endure 1,200 degrees heat fuel packet shell has melted. This suggests that, since after the earthquake nuclear reactors automatically shut off about 1 days since, radioactive substances, the spread of nuclear accident still continue reached very serious condition.

Large earthquake affected by 11, the first nuclear power plant, the Japanese f island happened leak of radioactivity, then unit 1 hydrogen explosion happened. The Japanese government put f island nuclear personnel evacuation range from the original fangyuan 10 kilometers rise to 20 kilometers, the second iman nuclear range from 3 kilometers near evacuation of ascending to 10 kilometers. The international atomic energy agency said that Japan is transferred from two plants nearby 17 million.
