酸化物分散強化型(ODS)フェライト鋼は、高速炉燃料要素用に開発している長寿命被覆管候補材料である。実証炉規模の高速炉で冷却材喪失(LOF)型および過出力(TOP)型の事故を想定した場合のODSフェライト鋼被覆管の破損耐性を累積損傷和(CDF)によって評価し、受動的炉停止システムが動作するまでCDFが破損目安値の1.0を十分に下回るという結果を得た。

Tolerance of fast rector fuel elements to failure in the typical accident conditions was evaluated for the oxide-dispersion-strengthened (ODS) ferritic steel claddings that are candidate of the cladding material for advanced fast reactors. The evaluation was based on the cladding creep damage, which was quantified by the cumulative damage fractions (CDFs). It was shown that the CDFs of the ODS ferritic steel cladding were substantially lower than the breach limit of 1.0 in the loss of flow and transient over power conditions until a passive reactor shutdown system operates.
