Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
141 words
AN INTEGRATED STEAM GENERTING NUCLEAR REACTOR SYSTEM OF THE TYPE WHEREIN HEATING SURFACES AT WHICH THE STEAM IS GENERATED ARE HOUSED IN THE SAME VESSEL AS A CORE OF THE REACTOR AND ARE HETED BY A PRIMARY COOLANT PASSED THROUGH THE CORE, SAID SYSTEM COMPRISING STEAM GENERATING TUBES CONSTITUTING THE HEATING SURFACES, INLET AND OUTLET HEADERS BETWEEN WHICH THE STEAM GENERATING TUBES EXTEND, SAID HEADERS BEING CONNECTED TO A STEAM CIRCUIT EXTERNAL TO THE VESSEL, AND CIRCULATING PUMP MEANS FOR CIRCULATING STEAM THROUGH THE SYSTEM, AN AUXILIARY BOILER MEANS FOR PROVIDING A STORE OF STEM UNDER PRESSURE, AND MEANS FOR SELECTIVELY INTRODUCING A FLOW OF THE STEAM STORED IN THE AUXILIARY BOILER MEANS INTO THE SAID OUTLET HEADER TO PROMOTE FLOW THROUGH THE STEAM GENERATING TUBES IN THE EVENT THAT THE CIRCULATING PUMP MEANS FAILS TO CURCULATE STEAM THROUGH THE SYSTEM.
