[2E05] Development of Estimation Technology of Aging Properties of Fuel Debris

(4) Micronization Characteristics Test of Zr(O)+(U,Zr)O2 Fuel Debris with Oxygen-containing Gas

*Akihiro Suzuki1, Yusuke Miura1, Yoshiyuki Kawaharada2, Shinya Miyamoto2, Shohei Kawano2,3 (1. NFD, 2. Toshiba ESS, 3. U Tokyo)

Keywords:fuel debris properties, chemical aging, radioactive particles, air exposure testing

前報にて空気雰囲気中にて放射線微粒子が発生すると特定したZr(O)+(U,Zr)O2の組成を有する燃料デブリに着目し、微粒子が発生するメカニズムを検討する目的で、模擬デブリ組成や環境中酸素分圧をパラメータとした加速試験を実施し、微粒子発生量が変化することを確認した。
