Abstract

The invention relates to a molten salt reactor buffer salt natural circulation cooling system. The system comprises an air natural circulation system and a molten salt natural circulation system which are intersected in an immersion-type plate air cooler. The immersion-type plate air cooler comprises a molten salt inlet, a molten salt runner, and a molten salt outlet sequentially formed on a vertical direction, and an air inlet, an air runner, and an air outlet sequentially formed on a horizontal direction. The air natural circulation system comprises an air inlet pipe and an air outlet pipe connected through the immersion-type plate air cooler. The molten salt natural circulation system comprises a molten salt inlet, a molten salt runner, a molten salt outlet, and a flow guide groove arranged on the downstream of the molten salt outlet. With the system, buffer molten salt can be directly cooled by using air, such that a middle circulation loop of an existing reactor design is eliminated, and cooling effect is improved. The system is maintained safe without dissipating reactor core power. The risk of accidents of a plurality of devices and pipes is avoided, such that system safety is improved.

Description

technical field [0001] The invention relates to the technical field of specially designed safety facilities for reactors, in particular to a buffer salt natural circulation cooling system for a molten salt reactor. Background technique [0002] After the nuclear reactor is shut down, due to the remaining fission in the core and the decay of fission products, the heat generated needs to be carried out of the core through a specially designed waste heat removal system. Otherwise, heat accumulation and temperature rise in the reactor may lead to nuclear safety accidents. After the molten salt reactor is shut down in an accident, the residual heat of the core is carried into the buffer salt in the molten salt pool, and a system is also required to passively cool the buffer salt. [0003] It is the development trend of today's advanced nuclear reactors to adopt the concept of passive safety design. For example, the AP1000 advanced pressurized water reactor designed in the Unite...
