放射性废物安全是全世界各国都极为重视的问题,已成为影响核能发展的制约因素之一。放射性流出物在满足核安全与放射性环境标准要求情况下,有控制地向环境排放是放射性废物安全管理的重要内容。为便于运行和管理执行,要求由营运单位提出排放管理目标值,审管部门批准后成为排放限值,而排放管理目标值是一个使剂量稍高于防护最优化结果,同时低于剂量约束的排放量。因此,按照防护最优化的原则对放射性流出物提出科学合理的排放管理目标值是问题的关键。
The safety of radioactive waste is a problem that all countries in the world attach great importance to and has become one of the factors that affect the development of nuclear energy. Radioactive effluent Controlled release to the environment to meet the requirements of nuclear safety and radioactive environmental standards is an important part of the safety management of radioactive waste. In order to facilitate the operation and management of the implementation of the requirements of the operating unit to set emission management targets, regulatory approval as emission limits, and emission management target value is a slightly higher dose than the protective optimization results, while below the dose constraint Emissions. Therefore, developing a scientific and reasonable emission management target for radioactive effluents based on the principle of protection optimization is the crux of the issue.
