The nuclear fuel of light water Pressurized Water Reactor (PWR) is fabricated as thin nuclear fuel pins assembled in an open square array of usually 17 x 17 or 18 x 18. The assembly usually keeps the central location for instrumentation and keeps also 24 locations to allow, when needed for a control rod spider to pass through in and out. This cluster of fuel pins is usually called fuel assembly.
What else can I help you with?
A large modern nuclear power plant has approximately how many fuel assemblies in its core?
A large modern nuclear power plant typically has around 200-250 fuel assemblies in its core. Each fuel assembly contains numerous fuel rods that house the uranium fuel used to generate heat for electricity production.
What is core of nuclear reactor?
In the PWR and BWR types it is a matrix of fuel assemblies stabilised with zircaloy fittings, and with control rods in certain specified channels within this matrix. This is where the nuclear heat is generated, and this heat is carried away by a flow of very pure water circulated by large pumps and at a high pressure.
What part of the nuclear powerplant does the chain reaction occur?
The chain reaction in a nuclear power plant occurs in the reactor core, where nuclear fission reactions take place. Heat generated from these reactions is used to produce steam, which then drives turbines to generate electricity.
Name one type of nuclear reactor?
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
What is pwr and bwr?
I think you are talking about nuclear reactors. PWR is a Pressurized Water Reactor, and is the basis for most power generators. BWR is a Boiling Water Reactor. As the water is a major moderating component, controlling the speed and intensity of the nuclear reaction, the steam bubbles in a BWR can present a problem.
What are the six main parts of the nuclear reactor?
For a PWR, how about: Pressure Vessel, Closure Head Assembly, Core Support, Inlet/Outlet Nozzles, Fuel assemblies, Control Rods and Drive Mechanisms
How is nuclear energy separated?
In a nuclear reactor the nuclear energy released by fission appears as heat in the fuel rods, which is then transferred to the reactor coolant (ie water in PWR and BWR)

What is the most widely used nuclear reactor?
The pressurised water reactor (PWR)
Where do you get nuclear energy at?
A nuclear power reactor, mainly PWR and BWR types.
What are the basic parts of nuclear reactor?
For the PWR, the reactor core which is an array of fuel assemblies, inside a very strong pressure vessel made of thick steel. The top of the vessel is removable for fuelling, and also holds the control rods and their mechanisms. The whole thing is enclosed in a secondary containment. Also inside this is the primary circuit which circulates water through the core to carry away the heat produced by the fuel assemblies, and the secondary circuit steam raising units which send steam to the turbine.

How long are the fuel rods typically left in the reactor core in a BWR or a PWR?
The length of time we see fuel rods left in the core of a reactor will depend on the time it takes to deplete the nuclear fuel in those rods. Reactor design, specifically fuel rod design, and the rate at which the fuel is consumed during operation all have an effect. Typical life of the fuel in a nuclear reactor at a power station is several years.

Can you give an example of nuclear energy?
Yes, the pressurised water reactor (PWR)
