PRESSURIZED WATER REACTORS - mragheb.com
mragheb.comIn a Pressurized Water Reactor (PWR), the coolant is pressurized to about 2,200 psia using a pressurizer and is not allowed to boil. The pressurized water is then pumped to steam generators where steam is produced and then fed to the turbine plant for the production of electricity. The
Boiling Water Reactor (BWR) Systems
www.nrc.govThe control cell assembly (page 3-5) is representative for boiling water reactor 1 through 6. Each control cell consists of a control rod (7) and four fuel assemblies that surr ound it. Unlike the pressurized water reactor fuel assemblies, the boiling water reactor fuel bundle is enclosed in a fuel channel (6) to direct

The guide tubes will be welded to the spacer grids and attached to the upper and lower end fittings. The guide tubes provide a channel for the movement of th e control rods and provide for support of the rods.
