METHODS OF EMERGENCY HEAT REMOVAL FROM POOLS AND STORAGES OF SPENT FUEL OF NUCLEAR POWER PLANTS

In the paper, consideration is given to possible methods of heat removal from water pools and storages of spent nuclear fuel of atomic power plants, which can be employed in an emergency due to failure of the regular cooling system of the pool. The authors present results of investigation of two passive methods of emergency cooling of spentfuel water pools: the fi rst method is to use emergency accumulator reservoirs with a cooling-water supply, and the second, to use boiling channels whose action is based on the effect of creating driving head in the emergency system of natural circulation of the cooling pond of the coolant.
