Claim 1
Independent Claim
134 words
AN INTEGRATED NUCLEAR REACTOR-STEAM GENERATOR SYSTEM OF THE TYPE WHEREIN HEATING SURFACES AT WHICH THE STEAM IS GENERATED ARE HOUSED IN COMMON WITH A CORE OF THE REACTOR IN A LIDDED VESSEL AND ARE HEATED BY A PRIMARY COOLANT PASSED THROUGH THE CORE, SAID SYSTEM COMPRISING STEAM GENERATING TUBES CONSTITUTING THE HEATING SURFACES AT WHICH THE STEAM IS GENERATED AND SUSPENDED FROM THE VESSEL LID TO BE REMOVABLE THEREWITH, A TRUNK DISPOSED INTERNALLY OF THE VESSEL TO SURROUND THE STREAM GENERATING TUBES AND THEREBY SEPARATE PRIMARY COOLANT FLOW OVER THE TUBES FROM A PRILMARY COOLANT RETURN FLOWPATH DEFINED BETWEEN THE TRUNK AND WALLS OF THE VESSEL, A TRUNK CLOSURE ALSO CARRIED BY THE LID TO CLOSE THE UPPER END OF THE TRUNK, AND A SEALING MEANS INTERPOSED BETWEEN THE TRUNK AND THE TRUNK CLOSURE.
