Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
A BOILING NUCLEAR REACTOR INCLUDING A CORE THROUGH WHICH IS CONVEYED A VAPORIZABLE LIQUID COOLANT, SAID CORE HAVING AN UPRIGHT CENTRAL PORTION AND AN UPRIGHT ANNULAR PORTION DISPOSED ABOUT SAID CENTRAL PORTION, MEANS TO SEPARATE SAID CENTRAL PORTION FROM SAID ANNULAR PORTION, MEANS, INCLUDING A PUMP, OPERATIVE TO ESTABLISH A FORCED CIRCULATION OF THE LIQUID COOLANT THROUGH THE CENTRAL PORTION OF THE CORE AND MEANS OPERATIVE TO ESTABLISH A NATURAL CIRCULATION OF THIS LIQUID COOLANT THROUGH SAID ANNULAR CORE PORTION.
Claim 2
Dependent Claim
80 words
A BOILING NUCLEAR REACTOR INCLUDING A CORE THROUGH WHICH IS CONVEYED A VAPORIZABLE LIQUID COOLANT, SAID CORE HAVING AN UPRIGHT CENTRAL PORTION AND AN UPRIGHT ANNULAR PORTION DISPOSED ABOUT SAID CENTRAL PORTION, MEANS TO SEPARATE SAID CENTRAL PORTION FROM SAID ANNULAR PORTION, MEANS, INCLUDING A PUMP, OPERATIVE TO ESTABLISH A FORCED CIRCULATION OF THE LIQUID COOLANT THROUGH THE CENTRAL PORTION OF THE CORE AND MEANS OPERATIVE TO ESTABLISH A NATURAL CIRCULATION OF THIS LIQUID COOLANT THROUGH SAID ANNULAR CORE PORTION.
Claim 3
Dependent Claim
88 words
IN A POWER PLANT SYSTEM THE COMBINATION OF A BOILING WATER NUCLEAR REACTOR HAVING A CORE DISPOSED IN A CONTAINER, SAID CORE HAVING A CENTRAL REGION AND A SEPARATE OUTER REGION DISPOSED THEREABOUT, MEANS FOR CIRCULATING WATER SERIALLY THRETHROUGH, MEANS FOR SUPPLYING WATER BELOW SATURATION TEMPERATURE FOR INITIAL PASSAGE THROUGH THE CENTRAL REGION, MEANS FOR SUPPLYING SAID WATER FOR INITIAL PASSAGE THROUGH THE OUTER REGION AND REGULATABLE MEANS FOR CONTROLLING THESE LAST TWO MEANS AND THE INTRODUCTION OF WATER THEREBY TO CONTROL THE POWER OUTPUT OF THE REACTOR.
Claim 4
Dependent Claim
88 words
IN A POWER PLANT SYSTEM THE COMBINATION OF A BOILING WATER NUCLEAR REACTOR HAVING A CORE DISPOSED IN A CONTAINER, SAID CORE HAVING A CENTRAL REGION AND A SEPARATE OUTER REGION DISPOSED THEREABOUT, MEANS FOR CIRCULATING WATER SERIALLY THRETHROUGH, MEANS FOR SUPPLYING WATER BELOW SATURATION TEMPERATURE FOR INITIAL PASSAGE THROUGH THE CENTRAL REGION, MEANS FOR SUPPLYING SAID WATER FOR INITIAL PASSAGE THROUGH THE OUTER REGION AND REGULATABLE MEANS FOR CONTROLLING THESE LAST TWO MEANS AND THE INTRODUCTION OF WATER THEREBY TO CONTROL THE POWER OUTPUT OF THE REACTOR.
Claim 5
Independent Claim
121 words
THE METHOD COMPRISING GENERATING HEAT VIA A NUCLEAR CHAIN REACTION IN A PREDETERMINED ZONE, ESTABLISHING A CIRCULATION OF WATER, PUMPING SAID WATER THROUGH A CENTRAL PORTION OF SAID ZONE, SUPPLYING SUFFICIENT HEAT TO SAID WATER IN PASSING THROUGH SAID CENTRAL PORTION TO VAPORIZE A PORTION THEREOF, RECEIVING THE STEAM AND WATER MIXTURE THUS PRODUCED AND SEPARATING THE STEAM FROM THE REMAINING WATER, CONVEYING THIS REMAINING WATER THROUGH SAID ZONE AT A LOCATION OUTWARDLY OF SAID CENTRAL PORTION WHERE THE POWER DENSITY IS DECREASED AND IN A LESS POSITIVE MANNER THAN THROUGH SAID CENTRAL ZONE AND SUPPLYING SUFFICIENT HEAT THERETO TO VAPORIZE A PORTION THEREOF, AND RECEIVING THE STEAM AND WATER MIXTURE THUS PRODUCED AND SEPARATING THE STEAM FROM THE REMAINING WATER.
Claim 6
Independent Claim
