During the in-service operation of nuclear power station, the irradiated fuel assembly drawn off from reactor needs first to be temporarily stored into the weary of fuel factory building
In fuel pit, handled after long-time cooling release waste heat, it is necessary to transport reprocessing plant to.In transport process, need
Spentnuclear fuel is fitted into shipping container and draws off from shipping container spentnuclear fuel.When unloading spentnuclear fuel, for spentnuclear fuel
The characteristics of Decay heat removal amount is big, it is desirable to which spent fuel transport container must is fulfilled for temperature requirement.Therefore Development and design one kind is needed to unload
Expect the cooling device of spent fuel transport container in cooling procedure.
The cooling system of spent fuel transport container is the indispensable auxiliary equipment that discharging operations are carried out to spent fuel transport container,
It can be inflated exhaust, water-filling exhaust, Water-cooling circulating to spent fuel transport container, make more than spent fuel transport container satisfaction
It is required that, so as to realize the safety unloading of irradiated fuel assembly.
Utility model content
The purpose of this utility model is：A kind of cooling system for spent fuel transport container in discharge process is provided,
The discharge to spentnuclear fuel waste heat in spent fuel transport container is realized, the surface temperature of irradiated fuel assembly is reduced, auxiliary completes weary combustion
The safety of material component draws off work.
The technical solution of the utility model is as follows：It is a kind of to be used for the cooling system of spent fuel transport container in discharge process,
Waste gas recovery mouthful connecting plate type heat exchanger, plate type heat exchanger connection filter, the outlet of filter connection spent fuel transport container, plate
Formula heat exchanger is also respectively connected with three-way valve A and three-way valve B, three-way valve A connect respectively cooling water inlet, three-way valve B,
Three-way valve C, three-way valve B connection coolant outlet；And three-way valve C connects compressed air inlet with docking spentnuclear fuel respectively
Shipping container entrance is connected；Spent fuel transport container entrance is all connected with spentnuclear fuel transport appearance with spent fuel transport container outlet 13
Device.
There is temperature sensor A on pipeline between waste gas recovery mouthful and plate type heat exchanger, and in plate type heat exchanger and mistake
There is temperature sensor B on pipeline between filter.
The temperature sensor A or temperature sensor B can be used for detection temperature.
Remarkable result of the present utility model is：Discharging refrigerating function can be realized, can be discharged in spent fuel transport container
The waste heat of irradiated fuel assembly, reduces the surface temperature of irradiated fuel assembly, it is to avoid excessive temperature stress is made to fuel assembly involucrum
Into destruction；By valve transfer loop, so as to realize different functions.This design greatly simplify structure, increase
Practicality；Spent fuel transport container can be made full of boron water formation biological shielding, the effect of shielding radioactive substance is reached.Together
When reduce its irradiation intensity to environment, reduce personnel's radioactive dose and reduce its irradiation intensity to environment, reduction personnel are shone
Dosage.
