JMTRでは、原子炉運転中、定期的に1次冷却水をサンプリングし、放射性核種の濃度を測定している。本報では、JMTRの低濃縮化が完了した第108運転サイクルから、原子炉の改修のためいったん停止した第165サイクルまでに測定したJMTRの1次冷却水中の$$gamma$$線放出核種濃度,放射性ヨウ素濃度及びトリチウム濃度の測定結果をまとめたものである。

Concentrations of radioactive elements in primary cooling water were measured by regular sampling on reactor operation of the JMTR. The JMTR core was converted to low enriched uranium core at the 108th operation cycle, and the refurbishment of the JMTR has been started after the 165th operation cycle. Measured results of concentrations of $$gamma$$-ray release elements, radioactive iodine and tritium in primary cooling water were summarized during 108 - 165th operation cycles.
