Abstract:
1. A closure apparatus for an overflow opening disposed in a wall of a nuclear engineering plant, the nuclear engineering plant containing a containment including an interior and the wall dividing the interior into a plant space having a reactor pressure vessel and a primary cooling circuit and into an operating space being walkable during normal operation, the closure apparatus comprising: a closure element containing a bursting element, said closure element spring-loaded in a closed state; and an actuating apparatus acting, in a case of a temperature-dependent triggering, directly on said bursting element and resulting in a tearing of said bursting element, and automatically releases a flow cross section when a predetermined trigger temperature on a side of a surrounding area is reached, and said bursting element is configured such that said bursting element tears if said actuating apparatus has not yet been triggered, if a predetermined pressure difference between the plant space and the operating space is present.
