摘要
AP1000型核电机组电站放射性废物处理的特点决定了其预期氚排放总量可能高于同功率水平的传统压水堆核电站。在AP1000机组正常运行期间,除了需要加强氚排放的环境监测,更重要的是从源头优化管理和控制氚排放,最大限度地减少氚排放对环境的影响,保障环境安全和公众健康。本文简要介绍了压水堆中氚的产生,详细分析了AP1000机组液态和气载氚的产生和排放机制,给出了采用保守和优化方法计算的AP1000机组的预期氚排放量,讨论了AP1000机组氚排放量最小化的优化控制措施。无论单机组还是6机组厂址,AP1000堆型核电站氚预期排放量都满足我国相关标准限值的要求。
The features of radioactive waste treatment at the AP1000 nuclear power plant determine that the expected tritium release from AP1000 may be larger than that from traditional pressurized water reactor nuclear power plant with the same level.During the normal operation,the AP1000 nuclear power plant needs to strengthen environmental monitoring of tritium release,and it is more important to optimize the management and control of tritium release from source terms.By doing so,the impact of tritium release can be minimized,the public health and environmental safety can be protected.
