摘要
WWER1000反应堆压力容器辐照监督样采用焊接方式固定在压力容器内表面上,采用切割方法取下,为评估相关操作的辐射风险、制定恰当的辐射防护措施并确保辐射安全,需要研究相关辐射源项、辐射水平等问题;研究获得的结果有效地指导了相关实践工作,实践也证明该研究中所采用的辐射源项分析方法具有简洁、实用和偏安全的特点,可为类似工作所参考及应用。
The irradiated surveillance specimens are welted on the inner surface of WWER1000 reactor vessel. The specimens are withdrawed by melting and cutting the welding joint. The radiation sources and radiation level is analyzed in order to evaluate the radiation risks and choose the radiation protection measures. The radiation sources analytical method is verified, which is concise, good and safe in practice.
