T/TLRIA 0004-2018 Nuclear power reactor coolant pump O-ring seal used for sealing

Scope

Scope: This standard specifies the requirements, test samples, inspection rules, marking, packaging, transportation, and storage for O-ring rubber seals used in nuclear reactor coolant pumps. This standard applies to O-ring rubber seals used in nuclear reactor coolant pumps. Main technical content: This standard specifies the requirements, test samples, inspection rules, marking, packaging, transportation, and storage for O-ring rubber seals used in nuclear reactor coolant pumps. The performance requirements and test methods for O-ring rubber seals used in nuclear power generation. The appearance quality of O-ring rubber seals used in nuclear power generation shall comply with the relevant provisions of GB/T 3452.2 S level. The structure, dimensions, and tolerances of O-ring rubber seals used in nuclear power generation shall comply with the requirements of the agreement or GB/T 3452.1. For O-ring rubber sheets, accelerated aging simulation experiments are conducted using 60Coγ rays to simulate the aging process of the product in a radiation environment. The test requirements are as follows: 60Coγ ray radiation, normal temperature and pressure, and a cumulative radiation dose of 650kGy for the test samples. After irradiation, there should be no abnormal phenomena in the appearance, and the performance changes shall meet the requirements.
