What is the function of moderators in nuclear reactor?

Moderators are the substance that slows down the neutrons in nuclear reactors. Moderators are made up of materials with light nuclei that do not absorb the neutrons but slow down the speed of neutrons by a series of successive collisions.

What are the components of pressurized water reactor nuclear power plant?

The reactor coolant system of the pressurized water reactor (PWR) consists of a reactor vessel, steam generators, reactor coolant pumps, a pressurizer, and other elements . These principal components are interconnected by the reactor coolant piping to form a loop configuration.

What’s in a nuclear reactor?

Nuclear Fission Creates Heat

Reactors use uranium for nuclear fuel . The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. ... The heat created by fission turns the water into steam, which spins a turbine to produce carbon-free electricity.

What is the main function of moderator *?

Moderator: Moderator is a material used in a nuclear reactor to slow down the neutrons produced from fission . By slowing the neutrons down the probability of a neutron interacting with Uranium-235 nuclei is greatly increased thereby maintaining the chain reaction.

What is in the core of a nuclear reactor?

The reactor core contains the nuclear fuel (fuel assemblies), the moderator, and the control rods . The reactor’s core contains all the nuclear fuel assemblies and generates most of the heat (fraction of the heat is generated outside the reactor – e.g.,, gamma rays energy).

What are the components of thermal power plant?

• Fuel storage and handling plant.
• Water Treatment Plant.
• Steam Boiler.
• Turbine.

What are the three necessary components inside a reactor vessel?

A reactor pressure vessel (RPV) in a nuclear power plant is the pressure vessel containing the nuclear reactor coolant, core shroud, and the reactor core .

What are the 4 types of nuclear reactions?

• Fission.
• Fusion.
• Nuclear Decay.
• Transmutation.

What is the main purpose of nuclear energy Mcq?

What is the main purpose of nuclear energy? Explanation: Nuclear energy was developed by man as an alternate source of clean and cheap energy when compared to fossil fuels .

Which of the following is not a main component of thermal power plant?

Modern steam power plants work on which of the following cycle? What would be the most important factor under consideration for the site selection of a thermal plant? Which of the following are the main circuits of a modern thermal power plant?

Which of the following is not the component of nuclear reactor *?

Explanation: a reflector rather than a refractor is a component of nuclear reactor.

Which of the following is not the component of thermal power plant?

Out of the given options, the Surge tank or surge chamber is not a part of steam power plant. It is a part of Hydo power plant. Surge chamber acts as a reservoir of water and used to compensate in case of pressure drop or rise.

What makes the best moderator in nuclear power plants?

Explanation: Function of moderator is to reduce the energy of fast neutrons to thermal neutrons. ... Speed of the neutrons is reduced within a small number of collisions as the moderator possesses a high scattering cross section. Materials with low atomic mass number make best moderators. 5.

Which material is used in controlling chain reaction in a nuclear reactor?

Most commonly, Uranium U-235 is the fissionable material used in this chain reaction (as shown in Fig.

What is the overall efficiency of nuclear power plant?

Explanation: The overall efficiency of a nuclear power plant is around 30 to 40% . Efficiency is higher at high road factors. Therefore, a nuclear power plant is always operated as a base load plant. Explanation: Nuclear power plants need less area as compared to any other plant of same generation capacity.

What is the main purpose of tertiary loop of a PWR?

The plume of steam escaping from the tower of a nuclear power plant comes from a third loop of tertiary water that cools the condenser .

What substance acts as the moderator in a pressurized water generator?

The PWRs use light water as a moderator .

What fuel is used in PWR?

The PWR uses enriched uranium fuel with a slightly higher enrichment level than in a BWR. This is responsible for a higher power density within the reactor core. As with the BWR, the fuel is introduced into the core in the form of uranium-oxide pellets. A typical PWR will contain 100 tonnes of uranium.

How is nuclear energy made?

Nuclear energy originates from the splitting of uranium atoms – a process called fission . This generates heat to produce steam, which is used by a turbine generator to generate electricity. ... And, with no carbon emissions, it will remain an important clean energy resource for the future.

How are nuclear power plants different from other power plants?

Nuclear plants are different because they do not burn anything to create steam . Instead, they split uranium atoms in a process called fission. As a result, unlike other energy sources, nuclear power plants do not release carbon or pollutants like nitrogen and sulfur oxides into the air.

Who invented nuclear power plants?

Chicago Pile 1 was the world’s first nuclear reactor, built in 1942 by Nobel Prize winner Enrico Fermi . The reactor was built underneath the University of Chicago’s Stagg Field football stadium.

Where is the core in a nuclear power plant?

A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated . Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins.
