What is the function of heavy water in a nuclear reactor Mcq?

Heavy water can serve as a neutron moderator in a nuclear reactor, which slows down fast particles and encourages the fission reaction.

What is the function of heavy water in a nuclear reactor?

Heavy water is used as a moderator in some reactors because it slows down neutrons effectively and also has a low probability of absorption of neutrons.

What are 3 functions that water performs in a nuclear reactor?

Nuclear power plants generate almost one fifth of the electricity produced in the United States. The nuclear power cycle uses water in three major ways: extracting and processing uranium fuel, producing electricity, and controlling wastes and risks.

What is the function of a nuclear reactor?

A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilise the actual neutrons produced in the core.

IT\'S FUNNING:  Does cooler takes more electricity than fan?

Why heavy water is used as a moderator in thermal nuclear reactor?

In nuclear reactors, heavy water is generally used as a moderator because unlike normal water, which absorbs neutron, it slows down neutron without absorbing it.

What is heavy water give one use of heavy water?

Heavy water is used as a neutron moderator in nuclear reactors. Heavy Water is used for the preparation of Deuterium. Iso-topologues of many organic compounds are prepared with the help of deuterium oxide.

What is the importance of heavy water?

Following are the importance of heavy water. (i) It is extensively used as a moderator in nuclear reactors. (ii) It is used as a tracer compound in the study of reaction mechanism. (iii) It is useed for the preparation of other deuterium compounds such as CD4,D2SO4 etc.

What happens to the water in a nuclear reactor?

Water is a vital tool for all nuclear power stations: it’s used to cool their heat-generating radioactive cores. During the cooling process, the water becomes contaminated with radionuclides – unstable atoms with excess energy – and must be filtered to remove as many radionuclides as possible.

Why do nuclear reactors use water?

The most common types of nuclear power plants use water for cooling in two ways: To convey heat from the reactor core to the steam turbines. To remove and dump surplus heat from this steam circuit.

How much water is used in a nuclear reactor?

The Nuclear Energy Institute estimates that, per megawatt-hour, a nuclear power reactor consumes between 1,514 and 2,725 litres of water.

IT\'S FUNNING:  You asked: Is styrofoam a conductor of electricity?

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.

What is used in nuclear reactor?

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 is nuclear reactor Class 10?

A nuclear reactor is the most important part of a nuclear power plant. It is where the nuclear chain reactions occur that produce energy by fission. The heat thus produced can be used to produce electricity. The main purpose of a reactor is to contain and control the energy released.

How does a heavy water reactor work?

A heavy water reactor makes use of heavy water as its coolant and moderator. Deuterium works as a moderator as it absorbs fewer neutrons than hydrogen, which is extremely important as nuclear fission reactions require neutrons to carry out their chain reactions.

Which one of the following is heavy water used in nuclear reactor?

The heavy water produced is used as a moderator of neutrons in nuclear power plants. In the laboratory heavy water is employed as an isotopic tracer in studies of chemical and biochemical processes.

Is heavy water more effective solvent than ordinary water?

In nuclear reactors heavy water is used as a moderator. It has higher boiling point as compared to the ordinary water. Thus, it is more associated as compared to ordinary water. The dielectric constant is however higher for H2O, thus, H2O is a more effective solvent as compare to heavy water (D2O).
