The BWR is specifically designed to respond to pressure transients, having a "pressure suppression" type of design which vents overpressure using safety-relief valves to below the surface of a pool of liquid water within the containment, known as the "wetwell", "torus" or "suppression pool". All BWRs utilize a number of safety/relief valves for overpressure, up to 7 of these are a … WebNov 15, 2007 · The flow-control valve design is standard at the later BWR-5 and BWR-6 plants, which also use an M-G set to power the pump at low frequency (15 Hz) and low … Web- The control bars on a BWR are inserted from below. This requires more penetrations at the bottom of the reactor vessel. This is a big disadvantage for nuclear safety. The insertion mechanism is not gravitational. These penetrations must be inspected regularly. The repair of a penetration is complex and expensive. the italian job gamecube
