NSUF 65-SURV-81: EBR II-Surveillance

In March of 1965, a set of surveillance (SURV) samples was placed in the EBR-I1 reactor to determine the effects of irradiation, thermal aging, and sodium corrosion on reactor materials. Eight subassemblies (SURV 1-5 and SURV 8-10), containing 15 alloys used in the primary system of EBR-11, were placed in the EBR-I1 blanket (Row 12) at 370°C. In addition to the metal samples, these subassemblies also contained a section with shield graphite canned in Type304 stainless steel. Two other subassemblies (SURV 6-7) were placed in the primary sodium tank storage basket, also at 370"C, to separate thermal and radiation effects. Half of the alloy specimens were exposed directly to reactor sodium, while the remainder were in sealed tubes with a helium atmosphere. The graphite was contained in a 304 stainless steel can with a helium atmosphere. The alloys included Ampco Grade 18 aluminum bronze; Stellite 6B; Inconel X-750; T-1 tool steel; Berylco-25 (beryllium-copper); Types 304,347,416, and 420 stainless steel;Type 17-4 PH stainless steel; and tantalum.
