Duke Energy is requesting information on your sites' practices for calibration and optimization of gamma sensitive portal monitors and article monitors. Duke Energy's EnRad Laboratories is beginning the process of standardizing the calibration and optimization of our gamma sensitive portal and article monitors in our six site, eleven unit nuclear fleet as an initiative following the merger of Duke Energy and Progress Energy. We are requesting answers to the following questions:
1. What is your site's calibration source isotope for gamma sensitive contamination monitors? 2. What is your site's gamma sensitive contamination monitor optimization source isotope? 3. What is the basis for the calibration and optimization source isotopes selected? a. Manufacturer recommendation or other? 4. Do you use mixed isotope sources for calibration and/or optimization of gamma sensitive contamination monitors?
