Reactor core Nuclear measurement system uses advanced self-powered detector, it is mounted on the heap in-core of reactor 7, and neutron temperature is surveyed
Amount channel 5 be installed in reactor fuel component 8, single neutron temperature Measurement channel 5 include 7 self-powered detectors, several
Thermocouple thermometer and a supplement thermal resistance thermometer, can not only measure reactor core neutron flux, moreover it is possible to measure reactor core entrance
With the coolant temperature of outlet.
Currently, the neutron temperature Measurement channel 5 that nuclear power station single unit uses shares 54, it is respectively arranged in fuel assembly
Reserving hole in, for realizing the functions such as monitoring netron-flux density, reactor core entrance and refrigerant level, overall length nearly 13
Rice, is immersed in nearly 12 meters of reactor coolant part.
As shown in Figure 1, current, the neutron temperature Measurement channel 5 of nuclear power station be out of, pressure vessels top cover edge hole,
By protecting the guide pipe of tube assembly, it is inserted into the fuel assembly 8 of 7 reactor core of reactor.During reactor 7 reloads,
It needs to extract neutron temperature Measurement channel 5 to except reactor core, wait reload and then be inserted into neutron temperature Measurement channel 5
In the fuel assembly 8 of reactor 7.
Within the time that unit has run a phase in longevity, the extraction of neutron temperature Measurement channel 5 and installment work need to be carried out, changed
Following difficulty will be had when neutron temperature Measurement channel 5 is extracted with installation during material:
Neutron temperature Measurement channel 5 only has sub-fraction and exposes outside the top cover of reactor 7, when extraction, uses special hanger
It is stuck in channel top with rope, is such as encountered when pulling out motionless, it is firmly excessive, tripping or rope crack conditions will be caused；
When extracting with installation, neutron temperature Measurement channel 5 (length 13m, lower end outer diameter are 7.5mm) surface more light
Sliding, using rubber gloves, hand is easy to skid, very difficult underthrust or the extraction channel had an effect；
After running a phase in longevity due to neutron temperature Measurement channel 5, there are channel deformations and bending situation, greatly increase work
Make difficulty, unit single neutron temperature Measurement channel 5 often occurs and be difficult to all extract or install in place during all previous overhaul
It happens.
Based on the above circumstances, it is necessary to take measures to assist the extraction of neutron temperature Measurement channel 5 and installment work, increase this
The convenience of work.
Summary of the invention
It is extracted the purpose of the present invention is to provide a kind of neutron temperature Measurement channel and auxiliary clamp is installed, which can be steady
