Light water is used:
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
Light water is used in CANDU reactors as a coolant because it is an effective moderator, slowing down neutrons to sustain the nuclear chain reaction. Additionally, light water is abundant and inexpensive, making it a cost-effective choice for the reactor.
VC Summer Nuclear Power Station uses a Westinghouse "light water" reactor. "Light water" means that the nuclear reaction is moderated by regular H2O (as opposed to "heavy water" which uses a heavier Hydrogen isotope called "deuterium").
Coolant, such as water or a specific type of liquid metal, is used in a nuclear reactor to absorb the heat released during the nuclear fission process. The coolant carries away the heat and helps to regulate the temperature within the reactor to prevent overheating.
Heavy water (deuterium) functions as a moderator. It slows down fast neutrons released by fission reactions in order to allow the reaction to be sustained. Fast neutrons pass through the reactor before initiating another fission reaction.

The pressure vessel of a nuclear reactor contains the reactor core and helps to maintain a high pressure environment to prevent coolant water from boiling. It also serves as a barrier to contain radioactive materials and provide structural support for the reactor.
The primary function of a moderator in a nuclear reactor is to slow down the fast neutrons produced during fission reactions, making them more likely to cause additional fission events. This helps sustain a chain reaction by ensuring a sufficient number of neutrons are available to continue the process. Common moderators include water, graphite, and heavy water.
This is the function of the moderator, which may be heavy water, light water, or graphite
Water.
The moderator used in the nuclear reactor at Madras Atomic Power Station in Kalpakkam is usually heavy water (deuterium oxide) or light water (ordinary water). These moderators are important for slowing down neutrons produced during nuclear fission reactions to sustain the chain reaction in the reactor.
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
The coolant used in a pressurized water reactor is typically purified water. This water is pressurized to prevent it from boiling and is circulated through the reactor core to remove heat generated during the nuclear reaction.
In light water reactors it is uranium dioxide with the uranium enriched to 4-5 percent
The pressurised water reactor (PWR)
Normal water, or light water, absorbs too many neutrons to be an effective moderator in a nuclear reactor. This absorption can make it difficult to sustain a nuclear chain reaction. Instead, reactors often use heavy water or graphite as a moderator, which have lower neutron absorption rates.
