It's not immediately obvious but tall buildings store 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 Photo: Carefully controlled: Before it was closed in the 1970s, NASA's scientific nuclear reactor at radioactive isotopes. They're the atomic equivalents of wobbly old buildings: sooner or later, they're bound to fall apart, splitting into bits like a large building tumbling to the ground and releasing energy on the way. When large atoms split into one or more smaller atoms, giving off other particles and energy in the process, we call it nuclear fission. That's because the central part of the atom (the nucleus) is what breaks up and fission is another word for splitting apart. Nuclear fission can happen spontaneously, in which we case we call it radioactive decay (the conversion of unstable, radioactive isotopes into stable atoms that aren't radioactive). ...

Once steam has been produced, it travels at high Cooling Towers Perhaps the most iconic symbol of a nuclear power plant is the cooling towers, seen in Figure 4. They work to reject Many nuclear power plants simply put the waste heat into a river, lake or ocean instead of having cooling towers. Many other power plants like Efficiency The Typical nuclear power plants achieve efficiencies around 33-37%, comparable to fossil fueled power plants.

In a nuclear power plant, heat energy is generated by a nuclear reaction called as nuclear fission. Nuclear fission of heavy elements such as Uranium or Thorium is carried out in a special apparatus called as a nuclear reactor. A large amount of heat energy is generated due to nuclear fission. Rest parts of a nuclear power plant are very similar to conventional advantage of nuclear power plants. Also, there are large deposits of nuclear fuels available all over the world and, hence, nuclear power plants can ensure continued supply of electrical energy for thousands of years. About 10% of the total electricity of the world is generated in nuclear power plants. How does a nuclear power plant work? Heavy elements such as Uranium (U 235) or Thorium (Th 232) are subjected to nuclear fission reaction in anuclear reactor. Due to fission, alarge amount of heat energy is produced which is transferred to the reactor coolant. The coolant may be water, gas or a liquid metal. The heated coolant is made to flow through a heat exchanger where water is converted into high-temperature steam. The generated steam is then allowed to drive a steam turbine. The steam, after doing its work, is converted back into the water and recycled to the heat exchanger. The steam turbine is coupled to an alternator which generates electricity. The generated electrical voltage is then stepped up using a transformer for the purpose of long distance transmission. The image below shows basic components and layo...

Nuclear Power Plant Working What is a Nuclear Power Plant? Nuclear power is the most controversial of all forms of electricity generation. Evaluating its importance involves weighing political, strategic and often emotional considerations alongside the more usual technical economic and environmental factors that form the core elements of any power technology. 15% of the electricity generated worldwide. It avoids around 2.5bn tonnes of CO 2 emissions, so it makes a major contribution towards a sustainable electricity supply which achieves the goals in terms of economics, capability and the environment to a large extent. Recommended Videos Nuclear Fuel and the Nuclear Resource Nuclear reactors require nuclear fuel in order to function. This fuel is usually uranium although other elements, including plutonium, can also be used. Thorium, though not a nuclear fuel itself, can be turned into a suitable isotope of uranium in a nuclear reactor. Thorium is naturally occurring like uranium but plutonium is only produced during nuclear reactions so its main source is nuclear reactors. Uranium is present in most rocks and in seawater and is a relatively common element in the earth’s crust with an abundance similar to that of beryllium, molybdenum, tin, arsenic and germanium. It is found in relatively high concentrations in a few areas and it is these that provide the supply that is used for nuclear power. Nuclear Fuel Cycle The production of fuel for nuclear reactors and the handling ...

Clean energy is a hot topic. Headlines about But how do nuclear reactors work exactly? Our largest source of clean energy uses a process you can’t see: fission. At nuclear power plants across the country, highly trained workers monitor an ongoing chain reaction that generates heat and steam, which is then converted to electricity using a turbine. Here are the three steps that reactors use to make clean electricity. Step One: Split Atoms to Create Heat Nuclear plants harness the incredible power of nuclear fission to generate heat and energy, which ultimately becomes electricity. Fission occurs when a neutron hits a larger atom and splits the atom into two smaller atoms. When a reactor starts, the uranium atoms in the reactor core split, releasing neutrons and heat, and kick off an ongoing chain reaction that generates more neutrons and heat. Learn More About Uranium and Nuclear Fuel While other power plants burn fuel to create steam and turn the turbine, nuclear power plants are unique. There is no fuel being burned to generate electricity – which means they do not emit carbon dioxide or greenhouse gases in the process. The only byproducts are energy and heat. There are Step Two: Use the Heat to Make Steam How do we get from fission to electricity? Water is in large part the answer. The reactor core (where uranium atoms are splitting) is immersed in water. As the chain reaction happens, the heat generated is used to create steam. There are two types of nuclear reactors in ...

The feedwater subcools the saturated water from the moisture separators. This water now flows down the downcomer or annulus region, which is separated from the core by a tall shroud. The water then goes through either jet pumps or internal recirculation pumps that provide additional pumping power (hydraulic head). The water now makes a 180-degree turn and moves up through the lower core plate into the nuclear core, where the fuel elements heat the water. Water exiting the...
