Description
Technical field
The invention belongs to nuclear power station neutron flux monitoring system technical field, and in particular to a kind of neutron temperature is surveyed
Measure the aid that passage hanger is installed.
Background technology
Neutron flux monitoring system (calling Nuclear measurement system in heap in the following text) is examined for the field distribution of heap power in reactor
Survey, the detection of reactor core local parameter etc., Nuclear measurement system is related to the protection of reactor in the heap of part nuclear power station, when
Parameter can form protection signal when exceeding permissible value and be sent to reactor protection system, in the instrument control system of nuclear power station
There is very important status in system.
Nuclear measurement system uses advanced self-powered detector in heap, and it is arranged on the appropriate position of reactor core, part
Nuclear power station then employs the measurement that more advanced neutron temperature Measurement channel carries out reactor core parameter.Often
Root neutron temperature Measurement channel accounts for the position of a fuel rod, including 7 self-powered detectors in heap in-core
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.
, it is necessary to by installed in the neutron temperature Measurement channel of heap core inner during nuclear power generating sets refueling outage
(NTMC) replacing of fuel could be carried out after extracting, treats neutron temperature can be measured after fresh fuel is in place
Passage is arranged on the position specified in fuel assembly.
, it is necessary to first be fixed NTMC tops using hanger before NTMC extraction and installation, in reaction
NTMC is extracted or inserted specified location by heap shaft top by the way of manually pulling with rope.On hanger
There are three full dog point socket sets, for NTMC tops are fixed within the sleeve of hanger, and three full dog point socket sets
Fixed tightness will determine whether NTMC is fixed firm, and such as hanger, which is fixed, there is a situation where to loosen, then
There will be the risk that NTMC comes off from hanger.
The content of the invention
It is an object of the invention to provide the aid that a kind of neutron temperature Measurement channel hanger is installed, the work
Tool can improve the stability that neutron temperature Measurement channel is fixed with hanger.
Realize the technical scheme of the object of the invention：The aid that a kind of neutron temperature Measurement channel hanger is installed,
The aid includes handle, driven rod and sleeve, and one end of driven rod is fixedly connected with handle, driven rod
The other end be fixedly connected with sleeve.
The cylinder underseal of described sleeve is closed, and the barrel both sides of sleeve are respectively provided with 1 opening, the cylinder bottom of sleeve
The heart is fixedly connected with driven rod.
2 openings on described sleeve wall are arranged circumferentially along it.
Described driven rod is fixedly connected with middle handle, and is mutually perpendicular.
Described handle, driven rod and sleeve uses stainless steel material.
The advantageous effects of the present invention：The present invention aid can by tightening full dog point socket set, from
And it is effectively guaranteed the stability that neutron temperature Measurement channel is fixed with hanger.Handle, driven rod and sleeve
Stainless steel is used for aid material, cheap, hardness is high, can preserve for a long time.
