The possibility of the commercial production of low-activation structural steels for fusion energy in the Russian Federation

Abstract

Laboratory meltings of low activation austenitic and ferritic steels (Fe0.1C12Cr20Mn1W0.2V and Fe0.1C9Cr1W0.15Ta) were done in an inductive furnace. The panoramic analysis of the charge materials and steels were made by means of spark mass-spectrometry. Series of calculations of activation parameters for steels composing from hypothetically pure, isotopically enriched macrocomponents and for real materials were conducted. The possible metallurgical technologies of industrial production of the low activation steels in the Russian Federation including processes of initial charge materials purification are considered.
