Workmanship Coupon Verifies and Validates the Remote Inspection System Used to Inspect Dry Shielded Canister Welds
The Idaho National Engineering and Environmental Laboratory (INEEL) is operated by Bechtel-BWXT Idaho LLC (BBWI), which recently completed a very successful Three-Mile Island-2 (TMI-2) program for the Department of Energy. This complex and challenging program loaded, welded, and transported an unprecedented 27 dry shielded canisters in seven-months, and did so ahead of schedule. 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.
