Hi All, Diablo Canyon uses a vendor to calibrate our whole body counters. After the calibration a daily QC check is done and the body counter is returned to service assuming it passes. The calibration documents are reviewed by RP when they are received from the vendor. The vendor is on our qualified suppliers list for whole body counter calibration.

We use a vendor to perform the calibration and the documentation is complete and has never been challenged, so I was stumped. We do QC checks on the daily performance to document the daily performance vs. the cal. What do you do for WBC calibration QA reviews? Especially if you use a vendor to perform the calibration.
