| 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. |
