中文摘要:
      以2014—2022年宁德核电厂周边海域每半年1次的采样监测数据为基础,对比分析3H的放射性分布情况,利用Spearman秩相关系数法、线性回归模型对海水中3H的活度浓度进行趋势分析。结果表明:研究期间宁德核电厂周边海域3H的活度浓度呈现缓慢的增长趋势;正常工况下,3H的活度浓度短期内仍将保持缓慢增长趋势,经过长期运行后,3H的活度浓度水平将保持稳定。
英文摘要:
      Based on the semi annual monitoring data of seawater around Ningde nuclear power plant from 2014 to 2022, the distribution of 3H radioactivity was compared and analyzed, and the trend of 3H activity concentration in seawater was analyzed by Spearman rank correlation coefficient method and linear regression model. The results indicated that the activity concentration of 3H in the sea area around Ningde nuclear power plant showed a slow increasing trend during the study period. Under normal conditions, the activity concentration of 3H would maintain a slow growth trend in the short term. After long term operation, the activity concentration level of 3H would remain stable.
