国際炉物理実験データ保存プロジェクト(IRPhEP)および国際臨界安全ベンチマークプロジェクト(ICSBEP)は、炉物理分野や臨界安全分野に使われているデータと解析方法の検証、核データの検証、先進的なモデリング&シミュレーションや規制活動に対して、積分実験データを評価し提供している。本論文では、(1)不確かさ評価と炉定数調整、(2)原子力機構での設計検討における不確かさ評価、(3)核データ検証、(4)臨界安全での応用、(5)工業用途への支援の5つの応用について紹介する。

The International Reactor Physics Experiment Evaluation Project (IRPhEP) and the International Criticality Safety Benchmark Evaluation Project (ICSBEP) provide evaluated integral benchmark data that may be used for validation of reactor physics / nuclear criticality safety analytical methods and data, nuclear data testing, advanced modeling and simulation, and safety analysis licensing activities. The handbooks produced by these programs are used in over 30 countries. Five example applications are presented in this paper: (1) Use of IRPhEP Data in Uncertainty Analyses and Cross Section Adjustment, (2) Uncertainty Evaluation Methods for Reactor Core Design at JAEA Using Reactor Physics Experimental Data, (3) Cross Section Data Testing with ICSBEP Benchmarks, (4) Application of Benchmarking Data to a Broad Range of Criticality Safety Problems, and (5) Use of the International Handbook of Evaluated Reactor Physics Benchmark Experiments to Support the Power Industry.
