Components of a Reactor

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 fission reactors made of?

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. Typically more than 200 of these rods are bundled together to form a fuel assembly.

What elements are used in nuclear fission?

Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission. The three most relevant fissile isotopes are uranium-233 uranium-235 and plutonium-239.

What are the main components of a nuclear reactor and what do they do?

Main components

The core of the reactor contains all of the nuclear fuel and generates all of the heat. It contains low-enriched uranium (<5% U-235) control systems and structural materials. The core can contain hundreds of thousands of individual fuel pins.

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 is the difference of fission and fusion?

Fission is the splitting of a heavy unstable nucleus into two lighter nuclei and fusion is the process where two light nuclei combine together releasing vast amounts of energy. While different the two processes have an important role in the past present and future of energy creation.

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).

How does a fusion reactor work?

In nuclear fusion you get energy when two atoms join together to form one. In a fusion reactor hydrogen atoms come together to form helium atoms neutrons and vast amounts of energy. … Two pairs of protons form to make two deuterium atoms. Each deuterium atom combines with a proton to form a helium-3 atom.

Which element is used as moderator in nuclear reactor?

In 1940 he discovered that beryllium is a good moderator (a material that slows down fast neutrons so they more readily split uranium atoms) and it has since been widely used in nuclear reactors.

What is the fission process in a nuclear reactor?

A nuclear reactor is driven by the splitting of atoms a process called fission where a particle (a ‘neutron’) is fired at an atom which then fissions into two smaller atoms and some additional neutrons.

What is fission and fusion examples?

In fission energy is gained by splitting apart heavy atoms for example uranium into smaller atoms such as iodine caesium strontium xenon and barium to name just a few. However fusion is combining light atoms for example two hydrogen isotopes deuterium and tritium to form the heavier helium.

Why do heavy elements undergo fission?

Nuclear fission occurs with heavier elements where the electromagnetic force pushing the nucleus apart dominates the strong nuclear force holding it together. In order to initiate most fission reactions an atom is bombarded by a neutron to produce an unstable isotope which undergoes fission.

What is nuclear fission give an example?

Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. … For example the fission of one kilogram of uranium releases as much energy as burning around four billion kilograms of coal.

How is the fission of a uranium 235 nucleus induced?

The absorption of a “slow” neutron induces the fission of a uranium-235 nucleus. The uranium-235 absorbs the neutron and forms an unstable compound nucleus uranium-236.

What does the top of the pressurized water reactor consists of at primary system pressure?

What does the top of the pressurizer in pressurized water reactor consists of at primary system pressure? Explanation: The pressurizer is a pressure vessel with a heater at the bottom and water spray at the top. The top of the pressurizer is filled with steam at primary system pressure.

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

The PWRs use light water as a moderator. It does however absorb neutrons to the extent that slightly enriched uranium fuel must be used to obtain a continuous fission chain reaction. The light water also serves as the coolant and circulates through the reactor.

Do atomic bombs use fission or fusion?

An atomic bomb uses either uranium or plutonium and relies on fission a nuclear reaction in which a nucleus or an atom breaks apart into two pieces.

What happens to the uranium during nuclear fission?

During nuclear fission a neutron collides with a uranium atom and splits it releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits. These neutrons continue to collide with other uranium atoms and the process repeats itself over and over again.

Where does nuclear fission occur?

Explanation: Nuclear fission can happen in a nuclear reaction. An example would be in nuclear power plants where uranium is decayed into other substances. In this example a neutron reacts with uranium-235 to give krypton-92 barium-141 and 3 neutrons.

What does a reactor core do?

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.

What does the graphite core do in a nuclear reactor?

What does graphite do in Advanced Gas-cooled Reactors? The graphite bricks act as a moderator. They reduce the speed of neutrons and allow a nuclear reaction to be sustained.

How many control rods were in the reactor the control rods are made of what material?

The black assemblies are very absorbent: their 24 rods are made of an alloy bar of Silver-Indium-Cadmium (AIC) or boron carbide two materials that strongly capture neutrons.
