For a reality heap irradiation structure for presurized water reactor, comprise irradiation device and forming board; Porose on forming board, described irradiation device is placed in described hole and removably connects with described hole, in-pile component material sample and weld seam witness sample are packaged in irradiation device when in-pile component is installed, irradiation device is between coaming plate and cradle cylinder body, under the prerequisite not affecting coaming plate forming board structure inherent function, solve existing irradiation device can not carry out irradiation problem to reactor core internals.Stow in reaction period of reloading, implement insertion or the extraction of irradiation device by specific purpose tool.
As preferably, forming board is divided into top forming board, bottom forming board and middle part forming board, and wherein, what be positioned at the superiors is top forming board, and the hole on plate play supporting role to irradiation device; Being positioned at undermost is bottom forming board, the pore area cone angle on plate, and it positions irradiation device; All the other are middle part forming board, and the hole on plate is carried out spacing to irradiation device; On each layer forming board, the hole of same position is coaxial through-hole from top to bottom; Irradiation device is cylinder structure, and comprise 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 is used for encapsulation needs irradiated sample.
As preferably, real heap irradiation structure can be many groups, distributes, to meet multiple irradiation demand around coaming plate in circumference.
As preferably, this reality heap irradiation structure can also be used for Irradiation Test or encapsulation dose detector, possesses the function of simultaneously carrying out reactor structural material irradiation and in-pile irradiation.
As preferably, irradiation device top is compressed by reactor core upper plate, guarantees the stability of its structure under the various operating condition of reactor.When carrying out in-pile irradiation test, only the in-pile component irradiation sample in irradiation device need be replaced to and need irradiation sample, its contour structures remains unchanged.
When irradiation device is installed, irradiation device is inserted downwards successively by the hole on the superiors' forming board, through the corresponding mounting hole on each layer forming board, after installation in position, by the superiors' forming board for irradiation device provides axially mounting, orlop hole is pilot hole, mounting hole on the forming board of middle level carries out radial constraint to irradiation device, and the hole on the forming board of upper strata play supporting role to irradiation device.
The invention has the beneficial effects as follows, under the prerequisite not affecting coaming plate forming board structure inherent function, the present invention can provide mounting interface for irradiation device, realize carrying out irradiation to in-pile component agent structure material and weld seam, for in-pile component agent structure material and the mechanical behavior in the weld seam military service phase provide reference, lengthen the life for in-pile component equipment and foundation is provided, simultaneously, other radioactive product can also be produced or carry out the radiation research of other material by irradiation, while solving domestic demand, improve the economy of nuclear power station.
