To present attractive advanced divertor systems with W- SiC/SiC by NITE process. Feasibility of divertor component fabrication with sufficient industrial background and sufficient performance verification 1- to define geometrical shapes and materials design to decrease the thermal shocks resulting not only from quasi-steady state plasma but also from  the thermal load resulting from off – normal events. 2- to accommodate the high heat flux loads with the W-SiC/SiC designs in different regions of divertor according to the intensity of the plasma (like baffle and dome ,outer and inner vertical target where each of  them has different plasma intensity) .

Based on the large scale production capability of NITE-SiC/SiC products at OASIS, Muroran Institute of Technology Extensive R & D efforts of advanced divertor with W-SiC/SiC systems are on-going including collaborative activities with BA, NIFS, JAEA and Universities W-SiC/SiC divertor systems will bring further attractiveness of Fusion Power Energy under realistic domestic R & D scenario Au (diverna) Organization of Advanced Sustanablity Interiver of Instrument Macram Muoram Institute of retrion. Muroran Institute of Technologyセラミックやセラミック複合材料を製造する際の中間素材(グリーンシートやプリプレグシート)を作成します。セラミック粉末やセラミック前駆体に樹脂等を混合したスラリーを基盤(キャリアーフィルム)上に薄く、膜状に作製したものをグリーンシート、強化繊維を含むものをプリプレグシートと呼びます。 Organization of Advanced Sustainability Initiative for Energy System/Material Muroran Institute of Technology (Warm Isostatic Press; WIP)セラミック複合材料の近似成型の中間処理や樹脂系複合材料の近似成型に用いられます。現状では最大17MPaの等方圧(静水圧)と最高200℃の加熱によるWIP処理により中間成型体であるプリフォームの成型や内部欠陥除去等行っています。
Muroran Institute of Technology HP処理とは、高温で一軸加圧を行う事で、セラミックや金属、及びそれらの複合材料などの成型や接合、材料内の欠陥の補修などを行う手法です。また、固体粒子の流動性を用いて熱間等方圧加圧(HIP)のような擬似静水圧状態での成型(擬似HIP)も行われます。 Organization of Advanced Sustainability Initiative for Energy System/Material Muroran Institute of Technology (Hot # Isostatic Press; HIP) HIP処理とは高圧ガスによる等方圧（静水圧）の負荷を高温で行う事により材料の成型を行い、焼結、拡散接合、内部欠陥の除去等を行うことです。NITE法を始めとして、セラミック複合材料の近似成型( Near-Net Shaping)や金属等との接合技術開発に主として用いられています。 HIP成型の原理高圧ガスにより試料に加わる等方的な圧力（静水圧）で成型します
