A research program is being conducted to determine the effects of high- temperature reactor-grade sodium and contaminants (O, C, N) on the tensile, creep, creep-to-rupture, and fatigue properties of Type 316 stainless steel and 2 1/4 Cr--1 Mo steel. Tests 1 (stainless steel in 1200 deg F lowoxygen sodium, air, and helium) and 2 (2 1/4 Cr--1 Mo steel in 1100 deg F low-oxygen sodium, air, and helium) were completed. Test 3 (stainless steel in 1200 deg F high- carbon sodium) was delayed. In Test 4 (2 1/4 Cr--1 Mo steel in 1100 deg F high- oxygen sodium), the creep rupture tests show a shorter life of both the original and exposed specimens in sodium with 300 ppm oxygen than with 30 ppm oxygen; the fatigue life was the same in sodium with 300 and 30 ppm oxygen; and the creep rate in sodium with 300 ppm oxygen was lower than with 30 ppm oxygen but still higher than in air or helium.
