PRESSURE RELIEF SYSTEM FOR THE CONTAINMENT OF A NUCLEAR POWER FACILITY, NUCLEAR POWER FACILITY AND METHOD OF OPERATING A PRESSURE RELIEF SYSTEM

摘要

A pressure-relief system for the containment of a nuclear power facility allows reliable operation of a wet scrubber for the pressure relief flow with a simultaneously compact structural design. The pressure relief system has a pressure relief line guided through the containment and can be closed by a shut-off valve, a wet scrubber arranged in a portion of the pressure relief line located inside the containment, for the pressure relief flow which forms in the pressure-relief mode when the shut-off valve is open, a reservoir arranged inside the containment and is fluidically connected to the remaining inner space of the containment such that any overpressure, with respect to the surroundings outside the containment, prevailing in the containment is transferred at least in part to the reservoir, and a supply line leading from the reservoir to the wet scrubber for supplying the wet scrubber with fluid from the reservoir.

主权项

1. A pressure relief system for a containment in a nuclear power facility, the pressure relief system comprising:
a shut-off valve; a pressure relief line guided through the containment and being closed by said shut-off valve; a wet scrubber disposed in a portion of said pressure relief line disposed inside the containment, for a pressure relief flow forming in a pressure-relief mode when said shut-off valve is open; a reservoir disposed inside the containment and fluidically connected to a remaining inner space of the containment such that any overpressure, with respect to surroundings outside the containment, prevailing in the containment is transferred at least in part to said reservoir; a supply line leading from said reservoir to said wet scrubber for supplying said wet scrubber with a fluid, acting as a washing fluid, from said reservoir; said wet scrubber having a washing fluid tank sealed off from a remaining inner space of the containment; and a throttle portion formed in a portion of said pressure relief line which is upstream of a point at which said pressure relief line passes into said washing fluid tank.
