North Anna is looking to change from an annual calibration that includes all counting geometries to a longer period of time between calibrations. We would appreciate any information, lesson learned, or concerns on this change. 1. What is your calibration frequency for your MCAs (annually, every 3 years, every 5 years, etc.)? 2. Have you changed frequency from an annual calibration to a longer period of time? 3. If so, what was your basis for changing the frequency? 4. Has this change been effective? Barbara J.
