This document describes the major components of the Clinch River Breeder Reactor Plant ex-vessel transfer machine (EVTM) and their recommended materials of construction. For parts that will be exposed to reactor atmosphere, Type 304 stainless steel is preferred unless (1) the design load requires higher strength material and/or (2) the moving parts come in direct contact in sodium. Parts operating outside the reactor atmosphrere will be fabricated of carbon or low-alloy steel. Because of the low total fluence (7.5 x 10⁴ n/m²), radiation embrittlement of the carbon or low-alloy steels will be insignificant. However, materials for the grapple chain and inflatable seals will be specified on the completion of the development testing at AI.
