Waste heat exhaust ventilation system for dry storage of spent fuel in nuclear power plants

摘要

A waste heat exhaust ventilation system for dry storage of spent fuel in a nuclear power plant, comprising a natural ventilation device and a forced ventilation device, specifically, a storage room, an operation room (20) and a ventilation equipment room (54 ), A cold air suction chamber, a hot air discharge chamber, a pipe, a ventilation heat shield cylinder (5), a heat exhaust fan, an air cooler (73), and the like, which are arranged corresponding to each other, are provided. According to this system, it is not necessary to store spent fuel in a pool storage system, and the safety of spent fuel does not depend on power equipment such as pumps and fans, so that daily maintenance is reduced and energy is saved. In addition to saving, it has inherent safety. [Selection] Figure 1
