FILTERS AND STRAINERS

12 Jun

When it is necessary to remove suspended solids from a liquid, the usual method is to filter or strain the liquid. The two methods differ only in the size of the mesh being used. Filtering removes the very small solids, and straining removes the larger solids. Because filtering and straining are for all practical purposes [...]

PRESSURIZERS

12 Jun

Pressurizers are used for reactor system pressure control. The pressurizer is the component that allows a water system, such as the reactor coolant system in a PWR facility, to maintain high temperatures without boiling. The function of pressurizers is discussed in this chapter.

Introduction
There are two types of pressurizers: static and dynamic. A static pressurizer [...]

DEMINERALIZERS
