All BWRs utilize a number of safety/relief valves for overpressure; up to 7 of these are a part of the Automatic Depressurization System (ADS) [1] and 18 safety overpressure relief valves on ABWR models, [2] only a few of which have to function to stop the pressure rise of a transient. In addition, the reactor will already have rapidly shut ...

The Automatic Depressurization System (ADS) consists of a series of valves which open to vent steam several feet under the surface of a large pool of liquid water (known as the wetwell or torus) in pressure suppression type containments (typically used in boiling water reactor designs), or directly into the primary containment structure in ...
Slightly different versions of the ABWR are offered by GE-Hitachi, Hitachi-GE, and Toshiba. [5]In 1997 the GE-Hitachi U.S. ABWR design was certified as a final design in final form by the U.S. Nuclear Regulatory Commission, meaning that its performance, efficiency, output, and safety have already been verified, making it bureaucratically easier to build it rather than a non-certified design.
Variable speed pumps were replaced with two-speed pumps (each rated at 35,400 US gallons per minute (2.23 m 3 /s) for a discharge pressure head of 865 feet (264 m)), and a flow control valve (adjustable from 22% open to 100% open with a linear flow response) was added to each loop for use in regulating recirculation flow (capable of regulating ...
An example of a safety system with passive safety components is the containment vessel of a nuclear reactor. The concrete walls and the steel liner of the vessel exhibit passive safety, but require active systems (valves, feedback loops, external instrumentation, control circuits, etc.) which require external power and human operation to function.
In a typical depressurization system, the goal is typically reduce the pressure in the plant to less than 50% of the design pressure or to 7 barg, whichever is lower, within 15 minutes. [ 2 ] Disposal of blowdown fluids is generally to flare systems or, if safe to do so, non-fired blowdown drums .
Ordinary valves can have many ports and fluid paths. A 2-way valve, for example, has 2 ports; if the valve is open, then the two ports are connected and fluid may flow between the ports; if the valve is closed, then ports are isolated. If the valve is open when the solenoid is not energized, then the valve is termed normally open (N.O.).
