WebIf the charging header pressure drops below reactor pressure, the ball check valve shuttles over and 1000 PSIG reactor water pushes the rod into the reactor. This is a slower scram, but is fail safe as well, using the reactor's own pressure to get the rods in. As long as the reactor is above 600 PSIG, the rods will insert rapidly. WebJun 2, 2024 · A boiling water reactor is a type of light water nuclear reactor that is utilized to produce electric power. It is one of the most typical nuclear reactors used to generate electricity. In this type of reactor, a single water loop acts as the coolant, core coolant and the turbine steam source.
