摘要： A nuclear engineering plant (4) with a containment (2), whose interior chamber (14) is subdivided by means of a gas-tight partition wall (16) into a systems chamber (18) containing the reactor pressure vessel (8) and the primary coolant circuit (10) and into an operating chamber (20) which is accessible during normal operation, is intended to ensure a particularly high operational reliability, in particular also in incident situations, in which hydrogen is released in the systems chamber (18), with production and operational outlay being kept low. For this purpose, the invention provides a number of overflow openings (22a, 22b, 22c) in the partition wall (16), wherein the respective overflow opening (22a, 22b, 22c) is closed by means of a closure element (24) of a closure apparatus (26) which opens automatically when a trigger condition associated with the respective overflow opening (22a, 22b, 22c) is reached, and wherein closure apparatuses (26) which open both as a function of pressure and independently of pressure are provided. A closure apparatus (26) which is particularly expedient in this connection furthermore has a closure element (24) comprising a bursting film (50) or a bursting diaphragm, wherein the closure apparatus (26) is designed such that it frees the overflow opening (22a, 22b, 22c) automatically when a predetermined environment-side trigger temperature is reached.

摘要： The invention relates to a safety system (1) for a nuclear plant comprising a plurality of catalytic recombiner elements (40, 44) that trigger a recombination reaction with oxygen when hydrogen is carried along in a feed gas flow, which system safeguards a reliable removal of the hydrogen from the gas mixture with an especially high degree of operational safety even under comparatively extreme conditions or scenarios of said type. According to the invention, the recombiner elements and/or the flow paths interconnecting two recombiner elements each on the gas side are designed in such a manner that a pressure pulse (40) produced in the gaseous medium by an ignition during the recombination reaction in a first recombiner element (40) triggers a gas displacement process in the feed section of a second, adjacent recombiner element (44), said process having a flow rate of at least 5 m/s.
