What are the 5 main parts of a nuclear reactor?
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 the 4 parts of a nuclear reactor?
Components of a nuclear reactor
- Fuel.
- Moderator.
- Control rods or blades.
- Coolant.
- Pressure vessel or pressure tubes.
- Steam generator.
- Containment.
What does the top of the pressurizer in pressurized water reactor consist 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 are the components of pressurized water reactor nuclear power plant?
The major components are the reactor vessel, the core barrel, the reactor core, and the upper internals package. The reactor vessel is a cylindrical vessel with a hemispherical bottom head and a removable hemispherical top head. The top head is removable to allow for the refueling of the reactor.
What are the major components of nuclear reactor explain its functions?
Explain its essential parts with their functions. The essential components of a nuclear reactor are (i) fuel, (ii) moderator, (iii) control rod, (iv) coolant and (v) protection wall. (i) Fuel: A fissile material is used as the fuel.
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.
What are the main components of a light water pressurized water reactor PWR?
The primary system (also called the Reactor Coolant System) consists of the reactor vessel, the steam generators, the reactor coolant pumps, a pressurizer, and the connecting piping. A reactor coolant loop is a reactor coolant pump, a steam generator, and the piping that connects these components to the reactor vessel.
In which part of a pressurized nuclear reactor of nuclear power plant is steam produced?
The core inside the reactor vessel creates heat. Pressurized water in the primary coolant loop carries the heat to the steam generator. Inside the steam generator, heat from the primary coolant loop vaporizes the water in a secondary loop, producing steam.
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.
