Description
Technical field
The present invention relates to cleaning process and equipment technical fields, and in particular to a kind of finger sleeve cleaning process and the technique institute
Use equipment.
Background technique
Reactor core neutron flux measurement system is the critical system of nuclear power plant's reactor core status monitoring, and system reliability service is reactor core
The important leverage of safe operation.Neutron flux pipe is inserted into reactor fuel component, and pipe is outer directly to be contacted with primary Ioops coolant, is held
By the most intense radiation of reactor core；Channel in pipe as neutron flux measurement probe (miniature fission chamber).Measuring probe (miniature fission
Room) by the different entire reactor core neutron-flux level measurements of finger sleeve completion.
Measuring probe is driven by metal spiral cable, can be generated and be rubbed with fingerstall inside pipe wall when cable passes through finger sleeve
It wipes, generates metal powder；Simultaneously, to make to drive cable flexible movements during neutron flux measurement, instrument control can driven
Anti-bite dose of stainless steel (Nairobi) is brushed on cable, anti-bite dose can also be retained in finger sleeve.Thereby result in two influences:
1) after unit long-play, metal powder, the impurity in environment, anti-bite dose of (Nairobi) heap of the generation that rubs
Crystallization accumulates in finger sleeve in product, Gao Fuzhao environment down tube, generates channel bite, influences pile neutron flux measurement；
2) metal powder, the impurity in environment and the irradiation of the particulate matter long-term receipt reactor core in Nairobi in casing, occurs
Activation, with the aggregation of activation products and taking out of for spiral cable, room environment dosage can be increased significantly.
There are two the purposes of finger sleeve cleaning:
1, the metal powder, impurity of accumulation, crystallization, Nairobi are cleaned out in finger sleeve, are reactor core neutron flux measurement
It goes on smoothly and provides safeguard；
2, radioactivation product in finger sleeve is removed, Environmental dose rate is reduced, reduces personnel's irradiation dose.
Periodically carry out the guarantee that the cleaning of neutron flux pipe is unit reactor safety stable operation.
At present there are two types of cleaning method, mechanical cleaning and chemical cleaning, chemical cleaning step approximately as: 1, utilize one
Chemical solvent is imported into finger sleeve in plastic flexible pipe insertion finger sleeve, impregnates about 10 minutes, carries out devil liquor recovery；2, by deionization
Water imports finger sleeve, discharges on the spot after impregnating about 15 minutes；3, compressed air purging finger sleeve is utilized；4, finger sleeve is taken out
Vacuum.Existing solvent cleaning system includes that cleaning trolley (is mainly used for solvent soaking process, including sealed solvent tank, pressure stabilizing
Air supply system etc.), several more hoses of solvent being connected between cleaning trolley solvent tank and rolling wheel for winding small hose；
Several small hoses being connected between rolling wheel and finger sleeve；For the devil liquor recovery case of solvent recovery, several waste liquids that are connected to are returned
Receive the solvent recovery hose etc. between case and finger sleeve.
