CONTAINMENT VENT SYSTEM WITH PASSIVE MODE FOR BOILING WATER REACTORS (BWRS), AND METHOD THEREOF

摘要

A system and a method for a passive containment vent system for a Boiling Water Reactor (BWR). The system is capable of venting and scrubbing a gaseous discharge from the primary containment of the BWR over a prolonged period of time leading up to or following a serious plant accident, without the need for monitoring by on-site plant personnel. External electrical power is not required (following initial activation of the system) in order to operate the containment vent system. The system may protect the integrity of primary containment during and following the serious plant accident.

主权项

1. A containment vent system, comprising:
a containment vent line in fluid communication with primary containment of a Boiling Water Reactor (BWR); one or more containment valves in the containment vent line; and one or more pressure activated devices in the containment vent line, located downstream of the one or more containment valves.
