放射性废液贮罐制造过程中耐压试验和泄漏检测试验规范性研究

Normative Research on tests of Pressure and Leak Detection during the Manufacture of Liquid Radioactive Waste Storage Tanks

核设施运行过程中,因工艺、运行、检维修等过程产生放射性废液,这些放射性废液须安全贮存,以防泄漏对人员和环境造成污染和危害。放射性废液贮罐作为放射废液包容的一道重要屏障,也是放射性废液贮存设施的重要设备,其制造质量对设施安全运行有着重要影响,耐压试验和泄漏试验是放射性贮罐制造过程中的重要验证环节,本文通过分析现阶段制造过程中耐压试验和泄漏试验规范性情况,结合技术标准要求,提出相关管理建议和意见。

During the operation of nuclear facilities, radioactive waste liquid will be produced due to such as handling, operation, and maintenance. These radioactive waste liquids should be safely reserved to prevent leakage, or else, it will make pollution or harm to personnel and the environment. As an important barrier of containing radioactive waste, radioactive waste storage tanks are also an important equipment for storage facilities. The manufacturing quality of these tanks has a significant impact on the safe operation of the facilities. Pressure and leakage tests are important verification links in the manufacturing process of radioactive waste tanks. This paper analyzes the standardization of pressure and leakage tests in the current manufacturing process, and proposes relevant management suggestions and opinions based on technical standard requirements.
