How do pressurized water reactors work

WebHow Reactors Work Naval pressurized-water reactors include a primary coolant system and a secondary coolant system. The primary system circulates water, which is pressurized to … WebIn the BWR the water in the reactor core is permitted to boil under a pressure of 75 atmospheres, raising the boiling point to 285°C and the steam generated is used directly to drive a steam turbine. This steam is then condensed and recycled back to the reactor core. A schematic of a BWR is shown in Figure 17.1.
