Tell me about nuclear power in hindi language
Its chain reaction is much closer to what happens in a nuclear bomb and it doesn't work through a moderator. Either way, it helps if you understand what nuclear energy is and how it works—so let's forget the politics for a moment and take a closer look at the science.
Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear stations. The water coming from the cooling body of water is either pumped back to the water source at a warmer temperature or returns to a cooling tower where it either cools for more uses or evaporates into water vapor that rises out the top of the tower.
Between around andmore than 50 GW of capacity was under construction peaking at over GW in the late s and early s —inaround 25 GW of new capacity was planned. Using two unconnected loops of water and the heat exchanger helps to keep water contaminated with radioactivity safely contained in one place and well away from most of the equipment in the plant.
Nuclear power explained
The water is then pumped back into the steam generator and the cycle begins again. What do you think? A half-life is the amount of time it takes for half of a sample of a radioactive element to decay. One reason many people oppose nuclear power is because they think nuclear plants are like enormous nuclear bombs, just waiting to explode and wipe out civilization. Huge amounts of world energy have been produced from atoms ever since, but amid enormous controversy. It is so aligned to prevent debris from the destruction of a turbine in operation from flying towards the reactor. Nuclear power plants by Chris Woodford. Bombs need extremely pure enriched uranium, which is made by removing contaminants notably another isotope of uranium, uranium from naturally occurring uranium. After a facility has been completely decommissioned it is released from regulatory control, and the licensee of the station no longer has responsibility for its nuclear safety. Typically the hot coolant is used as a heat source for a boiler, and the pressurized steam from that drives one or more steam turbine driven electrical generators.
Problems with workmanship and supervision have created costly delays. Heat from nuclear fission is used to raise steam, which runs through turbineswhich in turn powers the electrical generators.
Thermal power plant in hindi
To start with, very different grades of uranium are used in power plants and nuclear bombs some bombs use plutonium, but that's another story. Since nuclear plants need huge amounts of cooling water, they're often built by the coast—but that makes them dangerously susceptible to rising sea levels and earthquake tsunamis. Water is pumped through the reactor to collect the heat energy that the chain reaction produces. Since the late s worldwide capacity has risen much more slowly, reaching GW in What is a chain reaction? That's the basic idea behind nuclear power. For instance, U is fissile which means that it is easily split and gives off a lot of energy making it ideal for nuclear energy. It was the first time protests reached such heights. According to a basic rule of physics called the law of conservation of energy , the energy released in a nuclear fission reaction is equal to the total mass of the original atom and all the energy holding it together minus the total mass of the atoms it splits into and all the energy holding them together. Countries without large fossil fuel supplies find nuclear an attractive option. Isotopes are atoms of the same element with a different number of neutrons. But a tall, unstable building is bound to collapse sooner or later and, when it does so, the materials from which it was built come crashing back down to the ground, releasing their stored potential energy as heat , sound , and kinetic energy the bricks could fall on your head! The main difference from the dismantling of other power stations is the presence of radioactive material that requires special precautions to remove and safely relocate to a waste repository.
They also contend that reactors themselves are enormously complex machines where many things can and do go wrong, and there have been many serious nuclear accidents. Photo: Chain reaction! Only Finland has stable repository plans, therefore from a worldwide perspective, long-term waste storage costs are uncertain.
