Patent ID: 8126107

Claim:
A nuclear engineering plant, comprising: a containment including an interior and a gas-tight intermediate wall dividing said 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; said gas-tight intermediate wall having a plurality of overflow openings formed therein, said containment further having closure apparatuses with closure elements each closing a respective one of said overflow openings, said closure elements opening automatically when a trigger condition associated with said respective overflow opening has been reached; a first group of said closure apparatuses opening automatically in dependence on a pressure level indication; and a second group of said closure apparatuses opening automatically independent of the pressure level indication; at least two closure apparatuses of said second group of closure apparatuses opening in dependence on a temperature level indication; each of said at least two temperature level indication-dependent closure apparatuses opening as soon as an atmosphere temperature at a measurement location in said plant space exceeds a predetermined trigger temperature selected for that respective temperature level indication-dependent closure apparatus; said at least two temperature level indication-dependent closure apparatuses being located at different elevations in the containment; and said at least two temperature-dependent closure apparatuses being configured such that one of said at least two temperature level indication-dependent closure apparatuses located at a lower elevation opens at a lower predetermined trigger temperature than another one of said at least two temperature level indication-dependent closure apparatuses located at a higher elevation.
