Problems solved by technology

The tritium produced in the breeding zone is mainly taken out by the hydrogen carried by the helium through isotope exchange and sent to the tritium recovery system. Therefore, a special tritium extraction circuit must be designed in the envelope to recover tritium. The design of the tritium extraction circuit is a very complex job

Abstract

The invention discloses a cooling and tritium extracting loop for a helium cooling solid state tritium multiplication covering layer multiplication unit. The loop comprises a pebble-bed zone of the multiplication unit. Two cooling plates are arranged in the pebble-bed zone. A helium cooling loop and a tritium extracting loop are arranged at one end of the pebble-bed zone. Helium in the helium cooling loop enters from a helium cooling loop gas inlet and enters the cooling plates after flow dividing by a bottom helium flow dividing cavity, then the helium enters a helium flow collecting cavity, and finally the helium flows out of the multiplication unit through a helium cooling loop gas outlet. Tritium extracting gas in the tritium extracting loop enters from a tritium extracting loop gas inlet and enters the pebble-bed zone after flow dividing by a bottom tritium extracting gas flow dividing cavity, tritium generated through reaction is taken away, then the gas enters a tritium extracting gas flow collecting cavity, and finally the gas flows out of the multiplication unit through a tritium extracting loop gas outlet. The requirement for cooling and tritium extracting of the multiplication unit is met, meanwhile, the cooling loop and the tritium extracting loop are integrated in a cavity, the functions of the cooling loop and the tritium loop are not affected, loop integration is achieved, and a tritium multiplication space is effectively enlarged.

Description

technical field [0001] The invention relates to a design of a cooling circuit and a tritium lifting circuit of a cladding multiplication unit, in particular to a cooling and tritium lifting circuit for a helium-cooled solid-state tritium breeding cladding breeding unit. Background technique [0002] With the development of industry and the gradual depletion of fossil energy, magnetic confinement fusion is one of the important research directions of energy development. Breeding cladding is an important component of future fusion reactors and one of the key technologies to realize nuclear fusion power generation. Its main functions include: tritium breeding; generation and removal of heat energy for power generation; removal of first wall surface heat flow and nuclear heat to make the temperature and stress of the cladding lower than the allowable value of the material. Breeding cladding can be divided into two types: solid cladding and liquid cladding according to the diff...
