Claim 1
Independent Claim
173 words
A METHOD OF CONTINUOUSLY COOLING A NUCLEAR REACTOR CORE BY A LIQUID COOLANT AND UTILIZING THERMAL ENERGY GENERATED THEREFROM IN AN EXTERNAL TURBINE AND CONDENSER SYSTEM, COMPRISING PLACING THE CORE IN A FREE-SURFACE POOL OF LIQUID HAVING A VAPOR PRESSURE BETWEEN ONE ATMOSPHERE AND THAT OF WATER AT 1000* FAHRENHEIT, CIRCULATING THE LIQUID ABOUT SAID CORE TO INCREASE EFFICIENT HEAT TRANSFER THEREFROM, MAINTAINING THE HEIGHT OF THE LIQUID COLUMN ABOVE THE CORE WITH RESPECT TO VARIATIONS IN CORE LIQUID TEMPERATURE SUCH THAT THE TOTAL PRESSURE EXERTED BY THE REACTOR VAPOR PRESSURE AND THE LIQUID COLUMN IS GREATER THAN STURATION PRESSURE AT CORE LIQUID TEMPERATURE AND IS CONTINUOUSLY MAINTAINED UPON THE CORE LIQUID TO PREVENT BOILING THEREIN WHILE PERMITTING VAPORIZATION FROM SAID FREE:SURFACE POOL, AND VARYING THE HEIGHT OF THE LIQUID COLUMN ABOVE THE CORE SO THAT THE OPERATING PRESSURE OF THE COOLANT VAPOR IS VARIED INDIRECTLY WITH RESPECT TO THE HEIGHT OF THE LIQUID COLUMN SO THAT THE POWER DERIVABLE FROM THE MOTIVE FLUID BY SAID EXTERNAL TURBINE AND CONDENSER SYSTEM IS VARIED.
