Thermomechanical design of the grazing incidence metal mirror of the Prometheus-L IFE reactor

N.M. Ghoniem, A. El-Azab1995年Fusion Engineering and DesignIF 1.7出版社

AbstractIn laser IFE reactors the reflectivity and absorptivity of the grazing incidence metal mirror (GIMM) depend on the neutron dose received by the mirror surface. In addition to this effect, surface deformation caused by neutron-irradiation-induced swelling and due to thermal load changes the focusing quality of the mirror. In the present work, we present the database for material selection of the final GIMM of the Prometheus-L IFE reactor. A unique design for the GIMM, which accounts for mirror surface deformation by thermal and swelling effects is then presented.

レーザーIFE炉において、斜入射金属ミラー(GIMM)の反射率と吸収率は、ミラー表面が受ける中性子線量に依存する。この効果に加えて、中性子照射誘起スエリングおよび熱負荷によって引き起こされる表面変形は、ミラーの集光品質を変化させる。本研究では、Prometheus-L IFE炉の最終段GIMMの材料選定のためのデータベースを提示する。さらに、熱効果とスエリングによるミラー表面変形を考慮したGIMMの独自設計を提示する。
