Gas discharge system for the safety containment of a nuclear reactor

摘要

A pressurized gas discharge system for the safety containment of a nuclear reactor includes a conduit structure connected to the containment and consisting of a plurality of modular conduit units which are flanged together end-to-end, each having flanged side openings with filter frame members including stainless steel fiber filter packs flanged thereto in end-to-end relationship. The filter packs extend fully across the frame members and have their circumferential edges clamped between the flanges of adjacent frame members so that in the clamped areas the filter packs are reduced in thickness to a fraction of their original thickness, the flanges having U-shaped members disposed on their faces such that the legs of the U-shaped member project toward the adjacent flange and provide two seal strips with the edges of the filter packs compressed therebetween.
