Chapter 2 PRESSURIZED WATER REACTORS © M. Ragheb 11/2/2008 2.1 INTRODUCTION In 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 reactor vessel and the associated steam generators, pressurizer, and coolant pumps are enclosed in a containment structure.
