Abstract

The invention discloses a containment filtering and discharging system of a twin-reactor nuclear power plant, and the containment filtering and discharging system comprises a single-reactor configured filtering and discharging assembly and a downstream discharging assembly which is shared by two reactors, wherein the filtering and discharging assembly comprises a containment penetrating piece penetrating a nuclear power plant containment and a containment discharging pipeline penetrating the containment penetrating piece to be connected with a nuclear power plant unit, the downstream discharging assembly comprises an exhaust main pipe which is shared by the two reactors and connected with the containment discharging pipeline and a nuclear power plant chimney which is shared by the two reactors and is used for accommodating the exhaust main pipe. The filtering and discharging assembly is respectively configured for the two nuclear power plant units, so that the filtering and discharging volume requirement when the containments of the two units are simultaneously over-pressured can be met, the two unit containments are free from being manually and alternately operated to discharge the pressure, and each unit is independently operated, so that convenience in releasing the pressure can be realized.

Description

technical field [0001] The invention relates to a safety system of a nuclear power plant, more specifically, the invention relates to a containment filtering and discharging system of a double-reactor nuclear power plant. Background technique [0002] The containment filtration and discharge system of the existing dual-reactor pressurized water reactor nuclear power plant is designed according to the requirements of common use of the dual reactors and non-seismic requirements. This design does not take into account the simultaneous serious accidents of two or more units at the same site. The mitigation capability of the dual-stack common containment filtration and discharge system after two severe accidents occurred simultaneously has been questioned. For the dual-stack shared containment filtration and discharge system, once a serious accident occurs to two units at the same time, although the containment of the two units can be relieved and discharged in turn by manual ope...
