Gas desorption properties of low-activation ferritic steel as a blanket or a vacuum vessel material

Yuko Hirohata, Kaoru Suzuki, Tomoaki Hino1998年Fusion Engineering and DesignIF 1.7出版社

AbstractThe gas desorption properties of low-activation ferritic steel (F82H) were evaluated by thermal desorption spectroscopy (TDS), and compared with those of austenitic steels (316SS and 316LSS). The major desorbed gas species of F82H were CO, H2O, CO2 and H2. The fraction of oxygen-containing species such as CO, CO2 and H2O to the total outgassing amount was 98%. The gas desorption behavior was very similar to the case of 316SS. The gas desorption spectra for F82H show the required prebaking temperature becomes higher than 700 K. For the F82H sample exposed to atmosphere, the gas desorption properties were examined. As the time of exposure increase, desorption amounts of H2O and CO largely increased. This increase may be due to the corrosion in atmosphere.

低活性フェライト鋼(F82H)のガス脱離特性を昇温脱離分光法(TDS)により評価し、オーステナイト鋼(316SSおよび316LSS)と比較した。F82Hの主な脱離ガス種はCO、H2O、CO2およびH2であった。総脱離ガス量に占めるCO、CO2、H2Oなどの酸素含有種の割合は98%であった。ガス脱離挙動は316SSの場合と非常に類似していた。F82Hのガス脱離スペクトルは、必要な予備ベーキング温度が700 Kよりも高くなることを示している。大気に曝露したF82H試料について、ガス脱離特性を調べた。曝露時間が長くなるにつれて、H2OおよびCOの脱離量は大幅に増加した。この増加は大気中での腐食に起因する可能性がある。
