Production of low activation steel; JLF-1, large heats Current status and future plan 1 Work suppo

Abstract Based on the excellent basic properties prior to neutron irradiation and under neutron irradiation up to 100 dpa, the 9Cr–2W type low activation ferritic steel (LAF). JLF-1, had been selected as one of the reference materials to the IEA low activation ferritic steels R&D activity. This paper provides the general information about the second large heat of JLF-1 steel. The basic property of thick plates (24 and 12 mm in thickness) and their welded joints together with the information about microstructure are also provided.
