Embodiment 1

[0025] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] like Figure 1~4 As shown, a pool reactor material irradiation supervision vertical channel, it includes the first leak detection device 8, the second leak detection device 9, the ring plug 1, the first double-channel silicon rubber sealing ring 5, the second double-channel silicon rubber Rubber sealing ring 12, nut 2, end cap 3, retaining ring 6, flange 4, straight pipe 7, and head 11. Their connection relationship is: the lower end of straight pipe 7 is set on the upper end of head 11, and the upper end of head 11 There is a second stress groove 13. After the straight pipe 7 is set on the head 11, it is compressed by the spinning process, and the lower end is connected by circumferential welding; the flange 4 is set on the outer wall of the straight pipe 7, and the flange 4 is reserved The edge of the first stress groove 15 and the ...

Abstract

The invention belongs to the field of reactor monitoring components, in particular to a material irradiation monitoring vertical channel of a pool type reactor. The material irradiation monitoring vertical channel comprises a first leakage detecting device 8, a second leakage detecting device 9, a ring plug 1, a first double-channel silicon rubber seal ring 5, a second double-channel silicon rubber seal ring 12, a nut 2, an end cap 3, a baffle ring 6, a flange 4, a straight tube 7 and a seal head 11. The invention aims to provide the material irradiation monitoring vertical channel which has good sealing performance and can be applied to the pool type reactor in practice.

Description

technical field [0001] The invention belongs to the field of reactor monitoring components, and in particular relates to a vertical channel for radiation monitoring of pool reactor materials. Background technique [0002] For pool-type research reactors, the material used for the core vessel of the reactor core is nuclear grade 6061-T6A1, which will produce physical and mechanical changes after being irradiated during the operation of the reactor. In order to ensure the safety of the reactor operation, special A vertical tunnel for reactor material irradiation supervision is set up. The material selected for this tunnel is the same as that of the core components of the reactor, and the same material is used as a test sample to be inserted into the tunnel for irradiation. Since the tunnel is located far from the core active In close proximity to the area, irradiated samples are used to monitor core vessel material. [0003] The vertical channel is a channel that runs through...
