原子力発電所の使用済燃料乾式貯蔵用の廃熱排出換気システム

Japanese Patent JP6550479

B2

The present disclosure relates to the technical field of reactor engineering, and provides a residual heat removal ventilation system for spent fuel dry storage facility of nuclear power plant, comprising a natural ventilation apparatus and a forced ventilation apparatus, specifically comprising a cold air intake chamber, a hot air removal chamber, a pipeline, a ventilation heat shield cylinder, a heat removal fan, and an air cooling equipment having certain connecting relationships and being correspondingly arranged in a storeroom, an operating room and a ventilation equipment room. The present system does not require storing spent fuel in a pool storage manner. The safety of the spent fuel does not rely on power equipment such as pump or fans, thus not only reducing routine maintenance, saving energy, but also has inherent safety. Furthermore, the present system can be used to cool spent fuel storage canisters within spent fuel storage facility of pebble bed high temperature gas-cooled reactor nuclear power plant, and discharge residual heat of spent fuel storage canisters to the external environment by means of combining forced ventilation and natural ventilation.
