Performance and remote maintenance of attachment schemes for Plasma Facing Components

J Palmer, S Chiocchio, C Damiani, M Irving, A Turner2001年Fusion Engineering and DesignIF 1.7出版社

AbstractThe divertor design for the ITER-FEAT fusion reactor is based on cassettes which comprise a reusable body and three sacrificial Plasma Facing Components (PFCs) expected to be replaced in a hot-cell a number of times during machine lifetime. Central to this maintenance approach are the PFC-to-cassette attachments which must be readily assembled/disassembled by remote handling methods and withstand severe mechanical and thermal loading conditions during machine operation. This paper describes the facilities, equipment and methods used to carry out extensive testing of two attachment schemes, shear keys and multi-links, in order to assess their in-service performance and suitability to remote maintenance operations.

ITER-FEAT核融合炉のダイバータ設計は、再利用可能な本体と3つの消耗品であるプラズマ対向機器(PFC)から構成されるカセットに基づいており、これらのPFCは装置の運転期間中にホットセル内で数回交換されることが想定されている。この保守アプローチの中心となるのは、PFCとカセット間の取付機構であり、これは遠隔操作による容易な組立・分解が可能であるとともに、装置運転中の過酷な機械的・熱的負荷条件に耐えうるものでなければならない。本論文では、2つの取付方式(せん断キー方式とマルチリンク方式)について、その運転中性能と遠隔保守作業への適合性を評価するために実施した大規模試験の施設、設備、および方法について述べる。
