Seam carries out the irradiation structure of irradiation, and it can not only realize the irradiation of in-pile component material of main part, is in-pile component clothes
Material property provides reference during labour, or in-pile component is lengthened the life offer foundation, meanwhile, its irradiation inside configuration
Other materials can be loaded and carry out Irradiation Test, the economy of reactor is improved, technical solution of the present invention is as follows：
A kind of real heap for presurized water reactor irradiates structure, including irradiation device and forming board；There is hole on forming board, institute
State irradiation device to be placed in the hole and be detachably connected with the hole, in-pile component material sample and weld seam witness sample
It is packaged in when in-pile component is installed in irradiation device, irradiation device is located between coaming plate and cradle cylinder body, not
On the premise of influenceing coaming plate forming board structure inherent function, solving existing irradiation device can not be to reactor core internals
The problem of carrying out irradiation.During reaction is stowed and reloaded, can be implemented by specific purpose tool irradiation device insertion or
Extract.
Preferably, forming board is divided into top forming board, bottom forming board and middle part forming board, wherein, positioned at the superiors
For top forming board, the hole on plate play supporting role to irradiation device；Positioned at it is undermost be bottom forming board, on plate
Pore area cone angle, it is positioned to irradiation device；Remaining is middle part forming board, and the hole on plate is entered to irradiation device
Row is spacing；The hole of same position is coaxial through-hole from top to bottom on each layer forming board；Irradiation device is cylinder structure, including
Body, bottom end plug, upper end plugs, bottom end plug and upper end plugs are connected with body upper and lower side respectively, and body, which is used to encapsulate, to be needed
Irradiated sample.
Preferably, real heap irradiation structure can be multigroup, around coaming plate in circumferentially distributed, to meet a variety of irradiation need
Ask.
Preferably, the real heap irradiation structure can be used for Irradiation Test or encapsulation dose detector, possess and carry out simultaneously
The function of reactor structural material irradiation and in-pile irradiation.
Preferably, irradiation device top is compressed by reactor core upper plate, it is ensured that it is under the various operating conditions of reactor
The stability of structure.When carrying out in-pile irradiation test, the in-pile component irradiation sample in irradiation device need to only be replaced
Into irradiation sample is needed, its contour structures keeps constant.
When installing irradiation device, hole of the irradiation device on the superiors' forming board is sequentially inserted into downwards, passed through
Corresponding mounting hole on each layer forming board, after installing in place, axially supporting is provided by the superiors' forming board for irradiation device,
Orlop hole is that the mounting hole on positioning hole, middle level forming board is carried out on radial constraint, upper strata forming board to irradiation device
Hole irradiation device is play supporting role.
The beneficial effects of the invention are as follows on the premise of coaming plate forming board structure inherent function is not influenceed, the present invention can be with
Mounting interface is provided for irradiation device, realizes and irradiation is carried out to in-pile component agent structure material and weld seam, be heap
Mechanical behavior in inner member body structural material and weld seam service phase provides reference, be in-pile component equipment lengthen the life offer according to
According to simultaneously, additionally it is possible to the other radioactive products of irradiation production or the radiation research for carrying out other materials, domestic demand is being solved
The economy of nuclear power station is improved simultaneously.
