ABSTRACT The sources and mechanisms for the tritium release into the primary coolant in the JMTR and the JRR-3M containing beryllium reflectors are evaluated. It is found that the recoil release from chain reaction of 9Be is dominant and its calculation results agree well with trends derived from the measured variation of tritium concentration in the primary coolant. It also indicates that the simple calculation method used in this study for the tritium recoil release from the beryllium reflectors can be utilized for an estimation of the tritium release into the primary coolant for a water-cooled research and testing reactors containing beryllium reflectors.

评估氚释放到用于研究和测试反应堆的主冷却剂中

摘要 评估了氚释放到 JMTR 和包含铍反射器的 JRR-3M 中的主冷却剂中的来源和机制。发现 9Be 链式反应的反冲释放占主导地位，其计算结果与一次冷却剂中氚浓度的测量变化趋势非常吻合。它还表明，本研究中用于从铍反射器释放氚反冲释放的简单计算方法可用于估计含有铍反射器的水冷研究和测试反应堆的初级冷却剂中的氚释放。
