Nuclear reactor vapor suppressing means
Abstract
Abstract AS IMPROVEMENT IN APPARATUS FOR SUPPRESSING VAPOR PRESSURE BUILDUP WITHIN A NUCLEAR REACTOR CONTAINMENT DUE TO AN ACCIDENT IN A REACTOR SYSTEM, SUCH AS A RUPTURE OF THE PRIMARY COOLANT SYSTEM, OR OTHER EVENT WHICH PRODUCES VAPOR WITHIN THE CONTAINMENT. THE IMPROVEMENT IS IN PROVIDING AS UPRIGHT TANK, THE LOWER END OF WHICH IS OPEN AND IMMERSED IN A POOL FLUID, SUCH AS WATER, WITHIN THE CONTAINMENT; AND PROVIDING EVACUATING MEANS CONNECTED TO THE OTHER END OF THE TANK TO CONTINOUSLY MAINTAIN THE SURFACE LEVEL OF POOL FLUID INTERNALLY OF THE TANK HIGHER THAN THE LEVEL THEREOF EXTERNALLY OF THE TANK. SINCE THE POOL FLUID EXTERNALLY OF THE TANK IS EXPOSED TO VAPOR PRODUCED AS A RESULT OF A VAPOR PRODUCING EVENT, ITS SURFACE LEVEL IS LOWERED AS PRESSURE BUILDS UP WITHIN THE CONTAINMENT, ALLOWING THE VAPOR TO ENTER THE TANK AND BE CONDENSED, THEREBY PREVENTING THE FURTHER BUILDUP OF VAPOR PRESSURE WITHIN THE CONTAINMENT.
