EVALUATION OF CIMCOOL CONTAMINATION IN NS SAVANNAH CORE 2 END PLUG CONNECTIONS

One of the fuel segments of the assembly prototype for Sav 2-5-G-E was destructively examined after a 3-1/2 month exposure in VBWR. A crack was found through one of the end plug threads, believed to be due to chloride stress corrosion attack. The end connector of the segment was purposely contaminated with Cimcool, a water soluble chlorinated hydrocarbon used as a machining lubricant, followed by an autoclave cleaning cycle. The results observed from the destructive examination and their analysis are presented. These results are also related to the conditions believed to be operating in the N.S. Savannah Core 2. A program, initiated to investigate the effect of chlorides on the end connectors, yields results applicable to the evaluation of Core 2 fuel performance.
