High temperature gas cooled reactor tritium-contained wastewater optimization collection system and technology

Abstract

The invention relates to a high temperature gas cooled reactor tritium-contained wastewater optimization collection system. The system is composed of a first closed-loop circulation system and a second closed-loop circulation system. The first closed-loop circulation system is formed by sequentially connecting a helium purification regeneration system diaphragm compressor, a helium purification regeneration system electric heater, a helium purification system molecular sieve bed, a helium purification regeneration system water and helium cooler, a helium purification regeneration system gas and water separator and an auxiliary molecular sieve bed. The second closed-loop circulation system is formed by sequentially connecting a helium purification regeneration system diaphragm compressor, a helium purification regeneration system electric heater, an auxiliary molecular sieve bed, a helium purification regeneration system water and helium cooler, and a helium purification regeneration system gas and water separator. By the adoption of the system and technology, high temperature gas cooled reactor tritium-contained wastewater can be effectively collected, the running time of a whole high temperature gas cooled reactor helium purification system is prolonged, efficient running of the helium purification system is kept, and the system and technology have great significance in implementation of industrialization of a high temperature gas cooled reactor technology.

Description

technical field [0001] The invention relates to an optimized collection system and collection process for tritium-containing waste water of a high-temperature gas-cooled reactor, belonging to the technical field of nuclear reactors. Background technique [0002] The high-temperature gas-cooled reactor is a high-temperature reactor with graphite as the moderator and helium as the coolant. A variety of gaseous radioactive impurities and chemical impurities will be produced during operation, such as carbon monoxide, carbon dioxide, hydrogen, water, oxygen, nitrogen, methane, gaseous tritium and krypton produced by fuel ball fission and thermal neutron activation of reactor internals, Xenon and other radioactive impurities. In order to control the level of impurities, ensure the safe operation of the reactor, and prevent the discharge of radioactive waste to the environment, it is necessary to purify the helium coolant, and collect tritium-containing wastewater and discharge it...
