Patent Number: 052672832
Section: claims

1. A nuclear reactor, comprising: a nuclear reactor core;  a containment surrounding said core;  a structure spacedly surrounding said containment and defining an annular space therewith into which radiation can leak upon a core-melt design-exceeding nuclear event;  an auxiliary equipment building adjacent said structure;  a depressurization system connected to an interior of said containment for depressurizing same, said system comprising:  an emergency evacuation system connected to said space for evacuating same upon the occurrence of a core-melt design-exceeding nuclear event and maintaining a subatmospheric pressure in said space, said emergency evacuation system including:  at least one suspended-matter filter connected downstream of said other molecular sieve and upstream of said blower; and  at least one active coal filter connected downstream of said other molecular sieve and upstream of said blower.  a plurality of assemblies of at least one metal fiber filter and at least one molecular sieve in series, said assemblies being connected in parallel between said space and said blower.  a plurality of assemblies of at least one metal fiber filter, at least one molecular sieve, at least one suspended matter filter and at least one active coal filter in series, said assemblies being connected in parallel between said space and said blower. 2. The nuclear reactor defined in claim 1 wherein said emergency evacuation system includes: 3. The nuclear reactor defined in claim 1 wherein said emergency evacuation system includes: 4. The nuclear reactor defined in claim 1 wherein said emergency evacuation system includes: 5. The nuclear reactor defined in claim 1 wherein the metal fiber filters and molecular sieves of each of said systems form a modular component.
