Fort Calhoun Station Reactor Engineering is looking to improve our Failed Fuel Action Plan (FFAP) by utilizing Noble Gas values as the basis for our Action levels.
Our current FFAP utilizes historic values of coolant activity and dose equivalent iodine. Because of our history with failed fuel (early 2000's) and our current status over the last 5 cycles (No fuel failures), the values we use for determining action levels are now non-conservative.
1) Do you utilize noble gas values for FFAP action levels ?
2) If yes what are your levels ? Have they been effective ? 3) Can you provide a contact to discuss noble gas values
4) If no, what do you use? 5) Are you considering noble gas values?

Joe, here's Exelon's procedure for BWR and PWR. Erich Wurz may be able to answer this better for our PWR's.
