Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
182 words
A SELF-REGULATING DEMAND-RESPONSIVE BOILING-WATER NUCLEAR REACTOR COMPRISING A PRESSURE VESSEL CONTAINING A MASS OF WATER, A REACTOR CORE CONTAINING MATERIAL FISSIONABLE BY NEUTRONS OF THERMAL ENERGY MOUNTED WITHIN THE PRESSURE VESSEL AND SUBMERGED WITHIN THE WATER, A SOURCE OF WATER CONNECTED TO THE BOTTOM OF THE PRESSURE VESSEL, A STEAM LINE CONNECTING THE TOP OF THE PRESSURE VESSEL TO A DEMAND SYSTEM FOR THE STEAM, SAID NUCLEAR REACTOR BEING OPERATED UNDER CONDITIONS SUCH THAT THE MASS OF WATER BOILS IN THE PRESSURE VESSEL, AN ANULAR REFLECTOR TANK LOCATED WITHIN THE PRESSURE VESSEL AND DISPOSED ABOUT THE REACTOR CORE, SAID REFLECTOR TANK BEING OPEN AT THE TOP TO THE INTERIOR OF THE PRESSURE VESSEL, A SOURCE OF PRESSURIZED GAS CONNECTED TO THE UPPER PORTION OF THE SURGE TANK, A SURGE TANK LOCATED OUTSIDE THE PRESSURE VESSEL, AND A PIPE CONNECTING THE REFECTOR TANK CONTHE SURGE TANK, SAID SURGE TANK AND REFLECTOR TANK CONTAINING A MASS OF WATER, WHEREBY CHANGES IN THE DEMAND FOR STEAM CHANGE THE STEAM PRESSURE IN THE PRESSURE VESSEL AND THEREBY CHANGE THE HEIGHT OF WATER IN THE REFLECTOR TANK.
