Israeli development: peaceful nuclear
Researchers from Ben - Gurion University in Beer Sheva special plugin developed for nuclear fuel. Component will use raw material for producing nuclear energy, without the ability to produce bombs from
Researchers from Ben - Gurion developed nuclear fuel additive, which can ensure that the fuel will not make use of to build a nuclear bomb. The development will allow manufacturers to supply nuclear fuel to countries seeking raw materials to build reactors - nuclear power for energy, raw material without fear will be used for military purposes.
Given that many Middle Eastern countries like Bahrain, Egypt, Kuwait, Libya, Malaysia, Nigeria, Oman, Cotter, Saudi Arabia, United Arab Emirates, and Yemen, are interested in building nuclear power reactors is of great importance excluding plutonium created them. "Said Prof. Yigal Ronen, co-research group that also includes Dr. Yogi Chen Shuvgerus Mr. Leonid Legoland. The findings will be published shortly in the prestigious journal Science and Global Security.
Nuclear fuel in nuclear power plants is characterized by two elements (isotopes) of uranium. One component is not fissile fissile second. However, non fissile component of nuclear reactor undergoes nuclear reactions that may require some of the elements becomes plutonium. Also plutonium fissile components including an fissile components. Amount of cracks components of nuclear power reactors generated sufficient to be able to use nuclear weapons.
In a study conducted at Ben - Gurion, was offered to the nuclear fuel additive made from one of the basic components - Amariciom. Extension is a small amount, by about 0.1%, but this amount is sufficient to neutralize the plutonium. Hamariciom pass reactor nuclear processes followed it became an ingredient of fissile plutonium. The amount of this component provides that the plutonium produced by nuclear power reactor can not be used for nuclear weapons.
To understand the danger posed to Japan, you should dive into the depths of the nuclear reactor in physical activity that occurs there. How does the production process of nuclear energy and what happens when he goes wrong?
How does a nuclear reactor works ?
Most nuclear reactors, including the power plant Fukushima Daic 's in Japan, are actually elaborate kettles boil water efficiently to produce electricity. They take advantage of the energy emitted by nuclear fission: breaking of a heavy atom into two smaller atoms.
The process gives off heat and neutrons are free if another atom receives one of these neutron it becomes unstable and moves also fission, releasing more heat and more neutrons. This chain reaction to support herself and produces regular and stable supply of heat for boiling water, driving turbines that produce electricity.
Electricity produced several nuclear power plants in Japan and elsewhere?
Japan operate 54 nuclear reactors that produce 280 billion kilowatt - hour per year. Japan is a world's third nuclear power after the United States and France, the International Agency data set - International Atomic Energy Agency.
Ass power Fukushima Daic J. severely damaged in the earthquake hit the northern Japan on March 11, 2011 are six of 54 of these miners. The station teamed up with Japanese electricity network in the '70s of the last century.
Worldwide nuclear reactors produce about 15% of worldwide electricity. Japan, 30% of electricity comes from its nuclear power stations. The United States produces more nuclear power, but the general rate of U.S. energy sources smaller, about 20%, after coal (45%) and natural gas (23%).
What fuel of nuclear power plant?
Most nuclear reactors operate on the last uranium "enrichment" with uranium 235, easily undergoing fission isotope (isotopes are atoms with different atomic mass of a particular element, they differ in the number of neutrons.)
The most common isotope in nature is uranium 238 (92 protons and 146 neutrons), but this isotope is not fissile, so electricity producers raise the concentration of uranium 235 (92 protons and 143 neutrons) to several percent. This concentration sufficient to sustain a continuous fission regular electricity production.
The enriched uranium packed round bars coated with a layer of protective metal, such as the alloy Carkoniom (Zr). Uranium core reactor rods immersed in water.
Reactor No. 3 Fukushima Daic 's running on fuel called mixed oxide (MOX) which also mix it with uranium and other fissile materials, plutonium produced as a used nuclear fuel or nuclear bombs decomposition.
How to Turn a nuclear reactor?
Nuclear fission takes place continuously depends on supply of free neutrons passing atom by atom: neutrons released from fission of one atom stimulate the fission of another atom. Way to stop a nuclear fission chain is therefore to intercept and stop the free neutron.
Nuclear reactor control rods may use elements such as cadmium (Cd), boron (B), or Hafnium (Hf) neutron known Abkoshrm swallow effectively. When there is a problem at the reactor, or Achsmpailim want to turn it off, they reduce the remote - far the control rods located in water depth reactor core to absorb neutrons and stop the nuclear reaction.
Is a nuclear reactor can melt even after the nuclear reaction was terminated?
Even if the control rods faithfully fulfilled their duties and stop the fission reaction, the uranium rods hold in themselves heat. Moreover, the decay, the smaller atoms created uranium nuclear dismantling, are their Vahahatprkweut radioactive heat release. Therefore, the reactor continues to emit heat and also produce Achsahabicoa stops.
If the rest of the reactor are working correctly, the pumps will continue to pump cooling fluid (usually water) to remove the dormant reactor emits heat. In Japan, the earthquake caused the tsunami that followed power outages cut off the reactor's cooling systems. According to press reports, the backup generators (generators) of the power stations failed soon after leaving the miners not cooled in great danger of warming - the other.
Without a supply of liquid cooling, the hot reactor core might vaporize the water boil are the heart and expose the uranium rods. If the fuel rods are left exposed they may melt. When that happens, hot radioactive fuel begins to accumulate at the bottom of the hall containing the core.
Worst-case scenario of melting, nuclear fuel can puddle hot melt the steel holding the device and penetrate through, and through additional checkpoints and go outside. If they could escape a tremendous amount of environmental radiation.
How do I prevent melting of the reactor?
Reactor operators in Japan made some attempts to cool the reactors, including the pumping of sea water into the reactor to replace the coolant runs out. Tokyo Electric Company also flow reactors acid lye, a neutron absorbing material.
Is this event like previous events at Chernobyl and the Isle of Three Mile Island in the U.S.?
Ranked nuclear mishaps international scale of seven stages (INES scale), Japanese officials initially rated the problem a problem at 4, meaning "an accident with a local impact." But the physicist Frank von Hippel of Princeton University told the New York Times that the situation Fukushima Daic 's "far worse than it was Three Mile Island." This reactor failure, which was most severe in the U.S., was ranked at level 5 error, namely "accident with a broader impact."
Three Mile Island accident in Pennsylvania, which occurred in 1979 resulted from a combination of cooling system malfunction human error, and it caused partial melting: about half the reactor core and formed a puddle at the bottom came under pressure from steel. All the steel was not hurt, but radiation leaked into the environment.
The problem at Chernobyl in 1986 was far more devastating ranked at 7, or "big accident" INES scale. Power plant at Chernobyl in Ukraine, which was then part of the Soviet Union, made a quantum power reactors caused an explosion in one huge emission of radiation into the air. Two workers died within a few hours, according to a U.S. audit committee report. 28 workers died in the months that followed radiation poisoning.
Fallout from Chernobyl spread across a large area and therefore very difficult to determine accurately the effects on health. Report of the UN scientific committee determined that 6,000 people were when the explosion under the age of 18, stayed in Ukraine, Belarus or Russia, until 2006 had thyroid cancer, and that a small portion of people in line probably due to radiation exposure and disease.
