t Has caused damage to road infrastructure, railway houses, vehicles and aircraft equipment all in its path. Man killed over 20,000 people spread a large area without boundaries. And make uneasy mankind. Especially Japanese, which is the original legend of the tsunami. And moreover when the nuclear power plant Fukushima horse Ishii of Tokyo Electric Company. It is located near the northeastern coast of Japan has been affected. The damage is severe. Accidents that should be considered as a textbook, but only the imagination. However, the actual impacts of this damage was worse than ever as a record for the worst accidents in the same category. Whether it is a case of nuclear power plants. Three Mile Island in the U.S. or Chernobyl in Ukraine, the Soviet government. face="arial">
When an earthquake occurs, nuclear power plant Fukushima Mama, this will immediately stop working automatically. But the impact of floods and the tsunami in the equipment control room floor. Communication systems, all of which are at the heart of automatic control and emergency electrical power loss stop function collapse The casting to increase the cold water temperature to the fuel rods, which is located Rain World Branches. Cover with metal zirconate World Branches immersed in water with reactor control rods. Control engineers have made every effort to control the reactor temperature. Prevent fuel boiling stage to spread radioactive or explosive melting into the atmosphere. Playing together for a long time before deciding to use sea water to help cooling, but the results
much. To reduce the pressure of hydrogen gas in the cluster together outside the reactor building. Open to the atmosphere with subsequent negative effects. Explosive when mixed with oxygen. Explosion of hydrogen results in the outer canopy cover of a reactor device opened. Leakage of radioactivity into the atmosphere surrounding the very frightening. Yet fire and disaster prevention in Japan, it does not discourage Willing to risk for fire sprinkler temperature to sustain the reactor unit 3. The most critical problem of all six units. If this is an invaluable lesson of nuclear power engineering and power company, Tokyo Nuclear power plant Fukushima Mama, this has been built with the wisdom to know the maximum capacity of the Japanese engineers who are considered high security. With minimum risk in the world. Can withstand the force of the earthquake Richter scale is size 9. But when stamped with repeated impact of the huge hydro-speed 800 km per hour. It is beyond the expectation of the engineers who design As a result, electrical systems. Automatic control and safety equipment of all kinds of backup tumble out of paralysis. Yet the Japanese engineers and technicians also are trying to find measures running against time in order to control the operation of the reactor, all the computers in a safe condition to even be a security risk even their own.
Japan is a small island no alternative source of energy for much. Electricity from nuclear energy is necessary. Amounted to 30 percent of the total energy. Japanese know that their power is in a severe earthquake had a Richter 8.6 size and size in AD 1700 to 8.4 in 1933 but he was trying to use their knowledge and experience from disaster at worst. In the past, to determine the design and use of technology to minimize risk in the design, construction. For this technology to boiling water reactor is a high-temperature steam to spin the turbine generator. But other problems like A combination of hydrogen to explode and damage the electrical and emergency equipment from water damage and a tsunami that It is beyond expectations. Constitute a very painful learning.
Cause of the earthquake. Seismic risk must be accepted by humans stillness Divided into two categories.
1. Caused by the volcanic energy is still there. When the accumulated volume of lava and the temperature increased, the explosion. This explosion
caused a chain reaction to the earthquake waves vibrate around the perimeter. A limited field. 2. Caused by the contraction and expansion of the floor slab under the earth. Occurs when the boundary region of the Earth's surface area under the contraction of isolated stress from the area adjacent to the sudden deformation of the original. Releases the energy accumulated in the mass of the earth in the form of earthquakes, such as in the case of Sendai and December 26, 2547 the Indonesian island of Sumatra sent waves of a tsunami to coast-wide. A loss to the population of more than 150,000 of these people living in Thailand with 5,000 people died.
Seismic waves will spread out continuously every direction around a track divided vertically split. Depth and horizontal to the surface world in size between different frequencies. 2-7 miles per second. Cause vibration damage to change the physical structure of nature. And all structural changes that are natural or built by human hands-free region. Volume of the material world to stretch or shrink to separate this When calculating the energy that is released will have as many as 2 million children a bowl of miles in depth where the earthquake occurred between 30-450 miles from the earth's surface. After the earth swaying violence. The earthquake appears to have small hands, the distance uncertainties. Might be a day or a year for up to 15 years. Areas vulnerable to
earthquakes. As often as possible area of the line groove reaching the earth and from time to time in the other. Scholars rely on statistical records. Such as areas along the edge of the Pacific coast North America and Asia in the Indian Ocean. Indonesian archipelago. Upper Burma and China, etc. Since such a large earthquake at 8.3 Richter on April 18, 2449 the People San Francisco and the city fire 3 consecutive days since the United States, research has focused specifically on the earthquake. One could say that the statistics of earthquake damage. Tend to be more severe in order 17 August 2542 earthquake in Turkey Size 7.4 Richter 16,000 people have died. September 27, 2542 earthquake in Taiwan Size 7.6 Richter 2,300 people have died. In the year 2551 China has killed 85,000 people. In 2553 the country of Haiti. 224,000 people have died and Sumatra. With more than 226,000 people died. Most recently, Sendai. Japanese size 9 Richter is estimated that the death of more than 20,000 people with a small number. Because Japan is a nation that is always ready for an earthquake disaster. Comparison of the severity of the earthquake. Formerly used Mercedes 12 Claire Lee scale is adjusted to current levels Richter scale by the CFO, Richter and Gutenberg. Using a strength of seismic waves measured from the fake Distance from the point of the 100 km at 0.8 seconds, extension 2800 as the strength of the waves that measured as 1 micron (0.001 mm) of the measurement site a Gram-Mo. Is a unit of Richter. Each unit has a different intensity ten times over. Engineering design. Structural design of buildings in the United States. Equipped with location-based resistance to vibration, earthquake risk at the event, called MC E typically depends on the level of the force of gravity between 0:07 to 0:08 in the world of the gravity force in the world. In Thailand, from 30 years of statistics about the earthquake was not light damage. Statistics from the nearby December 26, 2547 Size 9 Richter central North Island of Sumatra. On 22 January 2546 Size 7.3 Richter central island of Sumatra. On 22 September 2546 Size 7.3 Richter center over Rangoon, Burma 355 km The last time was a shock to a small building in Bangkok. Expected that the design of structural engineers for Thailand should be between 6 per cent of the force of gravity (0.06g).
