Abstract

The invention discloses a pressurization test device for a cladding tube. The pressurization test device for the cladding tube comprises a test rack, a test tube, a first sealing member, a second sealing member, a third sealing member and a fourth sealing member, wherein the test tube is arranged on the test rack, the test tube sleeves a part of the cladding tube, a first part of the cladding tubeextends out of the test tube from a first end of the test tube, a second part of the cladding tube extends out of the test tube from a second end of the test tube, a test cavity is defined between the test tube and the cladding tube, and a water inlet and a water outlet which are communicated with the test cavity are formed in the peripheral surface of the test tube; the first end and the first part of the test tube are sleeved with the first sealing member, the second end and the second part of the test tube are sleeved with the second sealing member, the third sealing member is arranged atthe first end of the cladding tube, and the fourth sealing member is arranged at the second end of the cladding tube. The pressurization test device for the cladding tube can be used for carrying outa simulation test of in-tube pressurization on the cladding tube in a high-temperature and high-pressure water environment.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a pressure testing device for cladding tubes. Background technique [0002] The cladding tube of PWR fuel is in the environment of high-temperature and high-pressure water. Under normal operating conditions, there is pressure generated by fission gas in the tube. Under accident conditions, the pressure in the cladding tube rises sharply, which will pose a serious threat to the safe operation of the nuclear power plant. [0003] In order to test the service performance of the cladding tube material of the PWR nuclear power plant, a simulation test device for pressurizing the cladding tube in an environment of high temperature and high pressure water is needed. Contents of the invention [0004] For this reason, the embodiment of the present invention proposes a cladding tube pressurization test device, and the pressurization test device can perform a simulation test on the clad...
