[2E06] Development of Estimation Technology of Aging Properties of Fuel Debris

(5) Micronization Characteristics Test of Glassy Fuel Debris Containing (U,Zr)O2 Inclusions in Water

*Yusuke Miura1, Akihiro Suzuki1, Yoshiyuki Kawaharada2, Shinya Miyamoto2, Chiaki Shimoda2, Shohei Kawano2,3 (1. NFD, 2. TOSHIBA ESS, 3. UTokyo)

Keywords:fuel debris properties, chemical aging, radioactive particles, water sintering testing

前報にて空気平衡水中にて放射線微粒子が発生すると特定した(U,Zr)O2介在ガラス状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、模擬デブリ組成や水中平衡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。
