We’re looking for some OE regarding the use of Liquinox (Alconox) brand decontamination agent. We are seeing some odd results when deconning a spent fuel transfer cask that has a coating of (Carboline) Carboguard 890 epoxy. The cask is lifted from the pool, deconned successfully to less than 1k smearable and then allowed to dry. When rewetted, contamination appears at easily detectable levels, requiring significant additional decon. Does anyone else have experience with such a condition and, if so, what did you do to avoid the significant leaching (if that’s what it is)?Thanks, Eric Goldin, CHP RP Support, San Onofre Nuclear Generating Station 949.368.6727 [email protected] or [email protected]
