Trojan verified the tubes were not contaminated by removing random and low flow area tubes to verify no detectable contamination was present. That was when the plant changed out the condensers during power operation. During decommissioning, we used MARSIM sampling protocols and the DCGLs for the Turbine building systems for license termination.

Has any other PWR done this? Did you do any verification that they were not rad material? If so what did you do? We had small primary to secondary leaks a long time ago.
