NISP-RP-007 states that to release breakers, "The outer housing must be removed and accessible internal areas smeared. Pay particular attention to vents, housing seams, and oily/greasy areas. Ensure that you check the inside of springs (coils) for indirect contamination." At Comanche Peak, we have a list of non-suspect areas of the plant, in which many of our breakers are contained. Prior to implementation of the NISP, we would only perform a direct frisk/smear of external surfaces of the breaker if it was from a non-suspect area within the RCA. I was hoping to find some clarification on how other facilities are handling the release of breakers especially when considering the item is from a non-suspect area within the RCA.
