Amanda L. Stenson Exelon Corp - Braidwood NPS RP Technical Specialist (815)417-2712 From: [email protected] [mailto:[email protected]] On Behalf Of Benjy P Bertossi Sent: Friday, August 10, 2012 8:37 AM To: [email protected] Subject: Powernet: calibration periodicity What calibration periodicity (semi annual, annual, other) is used for RP/ HP equipment used at your facility... We are in the transition of moving everything to annual * handheld instruments Annual (except for Teletectors, Semi-Annual) * * continuous air monitors AMS4 = Annual, air samplers (H809V, HD28) = Semi Annual (per UFSAR) * * electronic dosimeters Annual * * stationary (PCM, SAM, etc) IPM/SAM/PM7 = Semi Annual, ARGOS/PM12 = Annual * * counting equip (WBC, gamma spec, alpha / beta counters) Annual * Do you allow a grace period (or extension of cal due date) for RP /HP equipment calibrations such as that specified in your TS / TRM for plant equipment surveillances? No, the cal frequency is based on the amount of OOT received during calibration. Every year, there is a report made to determine if an instrument shows the capability to transition to annual calibrations. Most instrumentation has shown that capability except for the ones mentioned above. The report includes information on how many instruments were calibrated and percentages of OOT. If the OOT % is less than 10% for the year, we can consider moving out the calibration frequency.
