A reactor using light water as moderator and coolant. The primary circuit including the reactor inside its pressure vessel is kept at a high enough pressure to suppress boiling, and the reactor coolant water is circulated through external steam raising units, where heat is transferred to secondary water at a lower pressure so that steam is produced, which then feeds a conventional steam turbine/generator. The uranium fuel is enriched in U-235 to 4-5 percent, and is in the form of uranium dioxide, made up into fuel rods 10mm in diameter and encased in zircaloy sheaths. A number of rods is made into an assembly which is the unit loaded and unloaded during refuelling outages. About 1/3 of the assemblies are changed in each fuelling outage, when the head of the pressure vessel is removed for access.

What else can I help you with?
What is the most widely used nuclear reactor?
The pressurised water reactor (PWR)
Can you give an example of nuclear energy?
Yes, the pressurised water reactor (PWR)
What is the advantage of using a pressurised nuclear reactor?
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
State different names of thermal power plant?
Different types of nuclear plants: Pressurised Water Reactor (PWR); Boiling Water Reactor (BWR); Heavy Water Moderated Reactor (CANDU); Advanced Gascooled Reactor (AGR); Fast Breeder Reactor (FBR); Pebble Bed Gascooled Reactor; Water Cooled Graphite Reactor (RBMK). There are other ideas that only exist on paper.
What is PWR or BWR?
PWR stands for Pressurized Water Reactor, which uses pressurized water to transfer heat from the reactor core to the steam generators to produce electricity. BWR stands for Boiling Water Reactor, which directly produces steam in the reactor core to drive the turbines and generate electricity. Both are types of nuclear reactors used for power generation.
What are example of nuclear energy?
Most Answers are Founded Out By:Sun's Rays, Other Star's Rays ETC.what are objects that use nuclear energy?
Can you please send me a diagram to make a model of nuclear reactor?
Wikianswers does not do diagrams. If you go to Wikipedia article on Pressurised Water Reactors you will find a diagram there.

The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
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.
What are some nonexamples fo nuclear fission?
Burning wood, cooking food on a stove, and rusting metal are all examples of chemical reactions that are not examples of nuclear fission. Additionally, photosynthesis, respiration, and fermentation are biological processes which do not involve nuclear fission.
What are two types of reactors used in the US?
Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs) are two types of reactors commonly used in the US for generating nuclear power. PWRs use pressurized water to transfer heat, while BWRs use boiling water to produce steam for electricity generation.
Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
