[1O01] Cross Section Adjustment Methods Based on Minimum Variance Unbiased Estimate

*Kenji Yokoyama1, Akio Yamamoto2 (1.JAEA, 2.Nagoya Univ.)

Keywords:Cross section adjustment, Minimum variance unbiased estimation, Maximum likelihood estimation, Bayes' theorem, Normal distribution, Uncertainty, Covariance

最小分散不偏推定法に基づいて正規分布を仮定せずに、炉定数調整法の理論式を新たに導出した。分散の最小化対象として、設計対象炉心核特性、炉定数セット、積分実験核特性を設定し、3種類の理論式を導出した。
