Power plant using a steam-cooled nuclear reactor

Claim 1

IN COMBINATIN A STEAM-COOLED MODERATED NUCLEAR REACTOR FOR PRODUCING HIGH-PRESSURE, HIGH-TEMPERATURE STEAM, A MULTI-STAGE STEAM TURBINE CONSTRUCTED TO PARTIALLY EXPAND HIGH-PRESSURE STEAM, TO HAVE THE PARTIALLY EXPANDED STEAM WITHDRAWN AND REHEATED, AND THEN FURTHER EXPANDED THEREIN FOR PRODUCING USEFUL PWER, SAID REACTOR HAVING FIRST AND SECOND FUEL ASSEMBLIES, FIRST TUBULAR PASSAGE MEANS FORMING PART OF AND IN HEAT EXCHANGE RELATIONSHHIP WITH SAID FIRST FUEL ASSEMBLIES, SAID FIRST TUBULAR PASSAGE MEANS RECEIVING HIGH-PRESSURE SATURATED STEAM, SECOND TUBULAR PASSAGE MEANS FORMING PART OF AND IN HEAT EXCHANGE RELATIONSHIP WITH SAID SECOND FUEL ASSEMBLIES, SAID SECOND TUBULAR PASSAGE MEANS RECEIVING PARTIALLY EXPANDED STEAM, A CLOSED PRESSURE VESSEL DISPOSED OUTSIDE OF SAID REACTOR, SAID VESSEL BEING FILLED WITH WATER UP TO A PREDETERMINED LEVEL, FIRST CONDUIT MEANS CONNECTING A PREDETERMINED LEVEL, FIRST CONDUIT MEANS CONNECTING SAID PRESSURE VESSEL AT A POINT ABOVE THE WATER LEVEL WITH THE INLETS TO SAID FIRST TUBULAR PASSAGES, SECOND CONDUIT MEANS CONNECTING THE OUTLETS OF SAID FIRST TUBULAR PASSAGES WITH SAID PRESSURE VESSEL AT A POINT BELOW THE WATER LEVEL IN SAID VESSEL, THUS FORMING A CLOSED CIRCUIT PATH THROUGH SAID FIRST TUBULAR PASSAGES AND BACK TO THE SAID CLOSED VESSEL, A STEAM PUMP INTERPOSED IN SAID FIRST CONDUIT MEANS, A MOTOR DISPOSED TO DRIVE SAID PUMP, SAID PUMP REGULATABLE MOVING SATURATE STEAM FROM SAID CLOSED VESSEL, THUS TRANSFERRING NUCLEAR HEAT FROM THE FUEL ASSEMBLIES TO THE SATURATED STEAM, THE RESULTING SUPERHEATED STEAM BEING DE-SUPERHEATED ON RE-ENTRY TO SAID VESSEL BY CONTACT WITH THE WATER IN SAID VESSEL, THEREBY EVAPORATING SOME OF THE WATER IN SAID VESSEL, THIRD CONDUIT MEANS BRANCHING OFF SUPERHEATED STEAM FROM SAID SECOND CONDUIT MEANS AND CONNECTING IT TO THE HIGH-PRESSURE INLET OF SAID STEAM TURBINE, FOURTH CONDUIT MEANS CONNECTING A FIRST INTERMIDIATE STAGE OF THE STEAM TURBING WITH THE INLETS TO SAID SECOND TUBULAR PASSAGE MEANS SO AS TO LEAD PARTLY EXPANDED STEAM TO RE-ENTER THE REACTOR WHERE IT IS REHEATED, FIFTH CONDUIT MEANS CONNECTING THE OUTLETS OF SAID SECOND TUBULAR PASSAGE MEANS WITH AN INTERMEDIATE STAGE OF THE STEAM TURBINE LOWER IN PRESSURE THAN SAID FIRST INTERMEDIATE STAGE FOR FURTHER EXPANSION IN THE TURBINE.
