Description
Technical field
This utility model belongs to nuclear power station neutron flux monitoring system technical field, is specifically related to a kind of neutron temperature
The aid that degree Measurement channel hanger is installed.
Background technology
In reactor, neutron flux monitoring system (calling Nuclear measurement system in heap in the following text) is for the distribution inspection of heap power field
Survey, reactor core local parameter detection etc., in the heap of part nuclear power station, Nuclear measurement system relates to the protection of reactor, when
Protection signal can be formed when parameter exceedes permissible value and be sent to reactor protection system, in the instrument control system of nuclear power station
System has very important status.
In heap, Nuclear measurement system uses advanced self-powered detector, and it is arranged on the position that reactor core is suitable, part
Nuclear power station then have employed the most advanced neutron temperature Measurement channel and carries out the measurement of reactor core parameter.Often
Root neutron temperature Measurement channel accounts at heap in-core the position of a fuel rod, including 7 self-powered detectors
With several thermocouple thermometers, reactor core neutron flux can not only be measured, moreover it is possible to measure reactor entrance and
The coolant temperature of outlet, and can be used in the instruction of emergency reactor core level.
During nuclear power generating sets refueling outage, need to be arranged on the neutron temperature Measurement channel of heap core inner
(NTMC) just can carry out the replacing of fuel after extracting, treat that neutron temperature can be measured after in place by fresh fuel
The position that passage is specified in being arranged on fuel assembly.
Before the extracting and install of NTMC, need first to use hanger to be fixed on NTMC top, in reaction
Heap shaft top uses the mode rope manually pulled that NTMC extracts or inserts appointment position.On hanger
There are three full dog point socket sets, within being used for being fixed on NTMC top the sleeve of hanger, and three full dog point socket sets
Fixing tightness will determine that NTMC is fixing the most firm, as hanger fixes the situation about loosening that exists, then
The risk that NTMC comes off will be there is from hanger.
Summary of the invention
The purpose of this utility model is the aid providing a kind of neutron temperature Measurement channel hanger to install,
This instrument can improve the stability that neutron temperature Measurement channel is fixing with hanger.
Realize the technical scheme of this utility model purpose: the auxiliary that a kind of neutron temperature Measurement channel hanger is installed
Instrument, this aid includes handle, driven rod and sleeve, and one end of driven rod is fixing with handle to be connected,
The other end of driven rod is fixing with sleeve to be connected.
The cylinder underseal of described sleeve closes, and the barrel both sides of sleeve respectively have 1 opening, at the bottom of the cylinder of sleeve in
The heart is fixing with driven rod to be connected.
2 openings on described sleeve wall are evenly arranged along its circumference.
Described driven rod is fixing with middle handle to be connected, and is mutually perpendicular.
Described handle, driven rod and sleeve all use stainless steel material.
Advantageous Effects of the present utility model: aid of the present utility model can be special by tightening
Screw, thus it is effectively guaranteed the stability that neutron temperature Measurement channel is fixing with hanger.Handle, transmission
Bar and sleeve all use rustless steel to be aid material, low price, and hardness is high, can preserve for a long time.
