What are the major components of nuclear power generation?

What are the major components of nuclear power?

2.2 Components of a nuclear power station

  • The fuel. The elements that undergo the fission are generally uranium (U) or plutonium (Pu). …
  • The control rods. A nuclear fission reaction at criticality can be maintained by controlling the critical mass (as you heard about in Week 1). …
  • The moderator. …
  • The coolant.

What are the 5 main components of a nuclear power plant?

Any nuclear reactor that produces power via the fission of uranium (U-235) or plutonium (Pu-239) by bombardment with neutrons must have at least five components: nuclear fuel consisting of fissionable material, a nuclear moderator, reactor coolant, control rods, and a shield/containment system.

What are the two main materials used in the generation of nuclear energy?

Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2.

What are the 10 parts of a nuclear power plant?

What coolant is used in nuclear reactors?

A substance circulated through a nuclear reactor to remove or transfer heat. The most commonly used coolant in the United States is water. Other coolants include heavy water, air, carbon dioxide, helium, liquid sodium, and a sodium-potassium alloy.

How does a uranium nucleus split into two?

1. A uranium-235 atom absorbs a neutron and fissions into two new atoms (fission fragments), releasing three new neutrons and some binding energy. 2. One of those neutrons is absorbed by an atom of uranium-238 and does not continue the reaction.

How many types of nuclear reactors are there?

Six types of reactor (Magnox, AGR, PWR, BWR, CANDU and RBMK) have emerged as the designs used to produce commercial electricity around the world. A further reactor type, the so-called fast reactor, has been developed to full-scale demonstration stage.

Why is nuclear energy bad?

Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous, and just because nuclear pollution is invisible doesn’t mean it’s clean. … New nuclear plants are more expensive and take longer to build than renewable energy sources like wind or solar.
