Study on silicide fuel behavior during RIA

反応度事故時におけるシリサイド燃料ふるまいに関する研究

柳澤 和章

Yanagisawa, Kazuaki

反応度事故(RIA)を模擬したパルス照射試験を未照射シリサイド小型燃料板を用いて実施した。燃料板の破損しきい値,破損メカニズム、そして燃料板曲がりによる流路閉塞を、投入エネルギーと燃料板表面最大温度の関数として研究した。流路閉塞については、単一燃料板体系だけでなく、横流れを防止した3枚板燃料体系でも実施した。得られたデータは研究炉燃料の安全審査に有効であることが判明した。

Pulse irradiation tests; simulation of reactivity initiated accident (RIA) were conducted on un-irradiated silicide mini-plate fuels. A failure threshold and its mechanism as well as a water channel closure (plate bowing) were studied as a function of deposited energy and peak cladding surface temperature. For the latter, not only single plate configuration but also triplet plate configuration with a restricted cross flow was conducted. Obtained data is revealed to be useful for licensing of research reactor fuels.
