Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
123 words
A LIQUID HOMOGENOUS NUCLEAR REACTOR PROVIDING ULTIMATE PROTECTION OF THE SURROUNDING AREA AGAINST RADIOACTIVE CONTAMINATION COMPRISING A WATER BOILER REACTOR HAVING A WATER SOLUTION OF ENRICHED URANYL SALT SELECTED FROM THE CLASS CONSISTING OF URANYL NITRATE AND URANYL SULFATE FOR A CORE, CATALYTIC HYDROGEN-OXYGEN RECOMBINER MEANS, SEALED CLOSED CYCLE GAS RECIRCULATING MEANS OPERATING IN AN OXYGEN CARRIER MEDIUM AND CONNECTED TO ACCUMULATE AND RECIRCULATE THE GASES GENERATED IN SAID URANYL SALT SOLUTION THROUGH SAID HYDROHEN-OXYGEN RECOMMEANS FOR ABSORBING THE GASEOUS FISSION PRODUCTS GENERATED IN SAID SOLUTION WHEREBY THE HYDROGEN AND OXYGEN FORMED BY THE DECOMPOSITION OF SAID WATER UNDER IRRADIATION IN SAID CORE ARE CONTINUOUSLY RECOMBINED BY SAID HYDROGEN-OXYGEN RECOMBINER AND RETURNED TO SAID SOLUTION BY SAID SEALED CLOSED CYCLE GAS RECIRCULATING MEANS
Claim 2
Dependent Claim
86 words
AN IMPROVED GAS HANDLING SYSTEM FOR A WATERBOILER REACTOR COMPRISING A SEALED CLOSED CYCLE SYSTEM COMMUNICATING WITH THE CORE OF SAID REACTOR, SAID SYSTEM HAVING A CATALYTIC RECOMBINER A FISSION GAS ABSORBER, AND MEANS FOR CIRCULATING THE GASEOUS PRODUCTS FORMED BY REACTOR OPERATION THROUGH SAID SYSTEM IN AN OXYGEN CARRIER GAS MEDIUM, SAID CIRCULATING MEANS BEING ADAPTED TO DISTRIBUTE SAID GASES BETWEEN SAID RECOMBINER AND SAID ABSORPTION MEANS, AZND SAID CIRCULATION MEANS BEING FURTHER ADAPTED TO RETURN RECONSTITUTED WATER TO SAID REACTOR CORE FROM SAID RECOMBINER.
Claim 3
Dependent Claim
160 words
A NUCLEAR RESEARCH REACTOR CAPABLE OF BEING SAFELY OPERATED IN POPULOUS AREAS COMPRISING A WATER BOILER REACTOR AND SEALED CLOSED CYCLE GAS RECIRCULATING MEANS CONNECTED TO SAID REACTOR, SAID GAS RECIRCULATING MEANS COMPRISING CATALYTIC GAS RECOMBINER MEANS ADAPTED TO RECOMBINE THE GASES FORMED BY THE DECOMPOSITION OF SAID SOLUTION, MEANS FOR ACCUMULATING AND RECIRCULATING THE GASEOUS PRODUCTS OF SAID REACTOR THROUGH SAID RECOMBINER MEANS IN AN OXYGEN CARRIER MEDIUM MEANS INTERGRALLY CONNECTED WITH SAID RECOMBINER MEANS FOR ABSORBING THE GASEOUS FISSION PRODUCTS OF THE SOLUTION WITHOUT VENTING TO THE ATMOSPHERE, AND MEANS FOR MAINTAINING THE PRESSURE IN SAID GAS RECIRCULATING MEANS AT A CONSTANT PREDETERMINED LEVEL COMPRISING A FLEXIBLE BALLON CONNECTED TO SAID RECIRCULATING MEANS, PRESSURE SENSITIVE MEANS RESPONSIVE TO THE PRESSURE IN SAID GAS RECIRCULATING MEANS, AND SERVO MEANS FOR ADJUSTING THE VOLUME OF SAID BALLON IN RESPONSE TO SAID PRESSURE SENSITIVE MEANS IN A MANNER TO MAINTAIN THE PRESSURE IN SAID GAS RECIRCULATING MEANS AT A PREDETERMINED LEVEL.
