[2M04] Uncertainty quantification of prompt neutron decay constant using deterministic sampling for thermal scattering law of light water

*Taiyo MORIBE1, Yoshinari HARADA1, Hibiki YAMAGUCHI1, Tomohiro ENDO1, Akio YAMAMOTO1 (1. Nagoya Univ.)

Keywords:light water, thermal scattering law, prompt neutron decay constant, uncertainly quantification, deterministic sampling

軽水の熱中性子散乱則について、決定論的サンプリング法により複数のLEAPR形式ファイルを生成することで、水槽体系における即発中性子減衰定数の不確かさ定量評価を実施した。
