.are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). In the PWR, water at high pressure and temperature removes heat from the core and is transported to a steam generator. There the heat from the primary loop is transferred to a lower-pressure secondary loop also containing.

Pressurized Water Reactor - an overview | ScienceDirect Topics

The pressurized water reactor (PWR) also uses ordinary or light water as both coolant and moderator (Figure 17.2). However, in the PWR system the cooling water is kept under pressure so that it cannot boil. The PWR differs in another respect from the boiling water reactor; the primary coolant does not drive the steam turbine.
