The program moved over 340 canisters of TMI-2 core debris that had been in wet storage into a dry storage facility at the INEEL. Welding flaws with the manually welded purge and vent ports discovered in mid-campaign had to be verified as not effecting previous completed seal welds. A portable workmanship coupon was designed and built to validate remote inspection of completed in-service seal welds. This document outlines the methodology and advantages for building and using workmanship coupons.
