PWR Cycle


The Pressurized Water Reactor designs are similar for the units provided by the various manufacturers. Differences are illustrated by the table below:

Manufacturer MWt MWe Loops Pressurizer Reactor Coolant Pumps per Loop Steam Generators per Loop
Westinghouse 450-3000 167-1000 1-4 1 1 1
Framatome 2700-3600 900-1300 3-4 1 1 1
Babcock & Wilcox 2400-3000 800-1000 2 1 2 1
Combustion Engineering 2400-3600 800-1300 2 1 2 1
ABB 3000 1000 4 1 1 1
Mitsubishi 3000 1000 4 1 1 1

A number of simplified diagrams (courtesy Westinghouse) illustrate the design of the pressurized water reactor facilities. 

The following are colored perspective and arrangement drawings of

The flow paths are illustrated by a colored graphic flow diagram and a black and white line drawing. The following describes the flow path and the linked drawings illustrate, in detail, the composition and major parts of the components.
