Abstract: A CONTAINMENT SYSTEM IS PROVIDED FOR A SODIUM COOLED REACTOR HAVING A HEAT REMOVAL SYSTEM FOR REMOVING HEAT ENERGY GENERATED IN THE REACTOR DURING NORMAL OPERATION, WHEREIN THE CONTAINMENT SYSTEM LIMITS THE EFFECTS OF A BETHE-TAIT EXCURSION AND HEAT ENERGY RELEASED THEREBY AND PREVENTS THE TRANSMISSION OF DANGEROUS RADIATION TO THE ENVIRONMENT IN THE EVENT OF AN ACCIDENT IN THE REACTOR, THE CONTAINMENT SYSTEM HAS THREE MUTUALLY TELESCOPED CONTAINMENT SHELLS OF CONCRETE SURROUNDING THE REACTOR, THE SHELLS BEING FORMED RESPECTIVELY OF FLAT RECTANGULAR WALLS AND A FLAT RECTANGULAR CEILING. A PRESSURE RELIEF COMPARTMENT IS DISPOSED WITHIN THE INNERMOST OF THE SHELLS AND A HEAT SINK IS LOCATED IN THE COMPARTMENT AND HAVING A HEAT ABSORBING CAPACITY ADEQUARE FOR ADSORBING THE HEAT ENERGY RELEASED BY THE REACTOR IN THE EVENT OF AN ACCIDENT THEREIN AS WELL AS FOR ABSORBING THE HEAT ENERGY PRESENT DURING A SIMULTANEOUS FILAURE OF THE HEAT REMOVAL SYSTEM. THE INNERMOST SHELL IS RESISTANT TO PRESSURE AND IS AT LEAST PARTIALLY PENETRABLE BY GAS.
