Spent fuel pool cooling system

Abstract

The invention provides a spent fuel pool cooling system. The spent fuel pool cooling system comprises at least two first cooling pipes and at least one second cooling pipe. First ends of the first cooling pipes are water intakes, the water intakes are formed in the side wall of a spent fuel pool, second ends of the first cooling pipes are arranged in the spent fuel pool, and a first isolation valve, a first water pump and a first heat exchanger are sequentially arranged in each first cooling pipe in the direction from the first end to the second end of the first cooling pipe. A first end of the second cooling pipe is communicated with a first position of each first cooling pipe, a second end of the second cooling pipe is communicated with a second position of each first cooling pipe, and asecond isolation valve, a second water pump and a second heat exchanger are sequentially arranged in the second cooling pipe in the direction from the first end to the second end of the second cooling pipe. Therefore, the structure of the spent fuel pool cooling system is simplified, the reliability of the system is improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of spent fuel pools, in particular to a cooling system for spent fuel pools. Background technique [0002] The spent fuel pool is an important part of a nuclear power plant, and a cooling system is generally installed in the spent fuel pool. The cooling system of the spent fuel pool is to take out the heat generated by the decay of the spent fuel during the normal operation of the generator set of the nuclear power plant, so as to maintain the temperature in the spent fuel pool within the normal range. In practical application, the cooling system of the spent fuel pool generally includes multiple cooling pipes, and each cooling pipe is equipped with a separate water intake, water intake pipe, cooling water pump, heat exchanger and other components. It can be seen that the current spent fuel The structure of the cooling system of the pool is relatively redundant, and the use cost is relatively high. Conten...
