Ken, North Anna has implemented Efficiency Bulletin 17-21 for our portable instrumentation. Based on our evaluation on our instrument performance - all of our portable RP instrumentation are source checked weekly. No notable problems or reliability concerns have been identified since going to weekly source checks. We plan on performing an effectiveness review on this process in 2019.
