高速炉用MOXバイパック燃料の照射挙動解析コードを開発するため、炉外試験等で得られた知見をもとにバイパック燃料用挙動評価モデル群を構築し、それらをペレット型燃料用挙動解析コードCEDARに導入し、CEDAR-VIPAC版を整備した。このCEDAR-VIPAC版の解析機能を検証するためにロシアで照射されたMOXバイパック燃料の照射挙動解析を実施した結果、モデル化が適切に行えていることを確認できた。

In order to develop a vibro-packed MOX fuel performance analysis code, thermochemical and mechanical properties of the vibro-packed fuels were incorporated into a pellet type fuel performance analysis code CEDAR. Calculations were made by the developed code on a vibro-packed MOX fuel pin irradiated at BN-600 in Russia. Since the calculated results agreed well with the behaviors obtained from the experimental data, it can be concluded that the code was well modeled and qualitatively validated.
