- 出版タイプ： NA高速実験炉「常陽」にてマイナーアクチニド含有MOX燃料の照射試験を実施した。今回の試験では、アメリシウムを3\%及び5\%含有したAm-MOX燃料とアメリシウム及びネプツニウムを各2\%含有したNp/Am-MOX燃料を用いた。照射試験は高線出力での短期照射(10分間及び24時間照射)を実施し、「常陽」において最大線出力約430W/cmを達成した。照射後、照射燃料集合体試験施設において燃料ピンの照射後試験を実施した。X線CT検査の結果、10分間照射では燃料中央付近に密度低下が予測され、24時間照射では燃料中央に明確に中心空孔の形成が確認された。Japan Atomic Energy Agency executed the irradiation examination of the MA content mixed oxide fuel by Experimental Fast Reactor "JOYO". This examination was used that the mixed oxide fuel that contained Americium by 3\% and 5\%, and the mixed oxide fuel of Americium and Neptunium that contained 2\% for each. The irradiation examination executed a short term irradiation (For ten minutes and 24 hours) by the high linear heat, and achieved maximum linear heat about 430 W/cm in "JOYO". After it had irradiated it, the post irradiation examination of the fuel pin was executed in the Fuels Monitoring facilities. On the results of X ray CT examination, the result that the density decrease is forecast to the vicinity of the center of the fuel was obtained for ten minutes in the irradiation. The formation of the central void was confirmed to the center of the fuel in 24 hour irradiation.
