Abstract

The invention discloses a high-temperature reactor waste heat removal system. The system comprises a water-cooled wall heat exchanger (E1) in a cabin, and an air cooler (E2) and an expansion water tank (C1) which are arranged outside the cabin, wherein an outlet of the water-cooled wall heat exchanger (E1) is connected to an inlet of the air cooler (E2), and an outlet of the air cooler (E2) and an outlet of the expansion water tank (C1) are connected to an inlet of the water-cooled wall heat exchanger (E1) through a forced circulation control valve (V4); and bypasses are arranged at the inlet end and the outlet end of the forced circulation control valve (V4), and forced circulation pumps (P1) are arranged on the bypasses. A method of combining forced circulation and natural circulation is adopted in the invention, so the defects that an existing waste heat removal system is low in cooling rate, long in consumed time, not thorough in flushing and the like are fundamentally overcome.

Description

technical field [0001] The invention belongs to the field of nuclear power high-temperature gas-cooled reactors, and in particular relates to a high-temperature reactor waste heat discharge system. Background technique [0002] High-temperature gas-cooled reactor is a new type of reactor with the characteristics of fourth-generation nuclear power, and its main feature is its inherent safety. The function of the waste heat removal system is to take out the heat of the reactor cabin through natural circulation during the normal operation period of the reactor or after the reactor is shut down, so as to quickly cool down the cabin and control the temperature of the cabin below 200°C. The waste heat removal system currently designed is a closed system composed of the water wall inside the cabin, the air cooler outside the cabin and the expansion tank. The air cooler exchanges heat with the atmosphere to cool down, and finally circulates naturally to the bottom of the water wall...
