The property requirements for breeder reactor fuel cladding materials are extremely stringent. Alloys with low sodium corrosion rates are required to avoid loss of strength from wall thinning at reactor operating temperatures. Data obtained on the following alloys are described: A-286, Inconel 706, Nimonic PE16, AISI 316, M-813 (sintered), Inconel 718, AISI 310, and Alloy 330. Tests were carried out at 700/sup 0/C for 2000 hours at a sodium velocity of 6 m/s and an oxygen content in sodium of 1 ppM. Corrosion rates and major elements depleted are tabulated. It is concluded that A-286, Inconel 706, and Nimonic PE16 are highly promising commercial alloys for cladding purposes on the basis of corrosion resistance. 5 figures, 1 table. (RWR)
