[2J23] Tritium Release Source and Mechanism in Research and Testing Reactors

*Etsuo Ishitsuka1, Inesh Kenzhina2, Keisuke Okumura1, Quan Hai Ho1, Noriyuki Takemoto1, Yevgeni Chikhray3 (1. JAEA, 2. Gumilyov Eurasian National University, 3. Al-Farabi Kazakh National University)

Keywords:Research and Testing Reactors, primary coolant, tritium, neutron reflector, beryllium, recoil release

An increase of tritium concentration in the primary coolant for JMTR and JRR-3M revealed that the recoil tritium release from the beryllium reflector is dominant.
