Failed Fuel Action Levels - Based upon Noble Gas Data
by WILLETT, JOSEPH E 20 Feb '10

20 Feb '10

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? J. E.

FRI Performance Indicator
by aburger＠firstenergycorp.com 19 Feb '10

19 Feb '10

Please respond to following questions regarding fuel performance indicator. Thank you in advance. Beaver Valley (FENOC) issues Fuel Reliability Indicator (FRI) data monthly to be used internally (within FENOC) as a performance indicator. As such, the calculated FRI is used in conjunction with "any fuel defects" and assigned the following color-coded ranking: (Embedded image moved to file: pic24438.jpg) Currently, the BV-1 FRI is calculated to be 1.78E-6 uCi/gm, which places us outside the top decile (there are currently 28/67 PWRs in the top decile - all calculating a FRI of 1E-6). Naturally, this "uptick" (going from GREEN to WHITE) in the performance indicator is raising many eyebrows from upper management, even though none of our other indicators shows any indication of a fuel defect. Please respond to the following: 1. What combination of indicators do you use as input to your monthly fuel performance indicators (internal)? (i.e. no fuel defects, FRI, DEI, Xe-133 etc) 2. Please provide your method of ranking and any basis for the values used (i.e. either GREEN or RED; basis: no defects or some defects OR 1, 2, 3; basis: 1- fuel defects and in some admin action level, 2 - no definite fuel defects identified but some admin limits exceeded, 3 - no defects and no admin limits exceeded OR any other ranking method) 3. Please provide the frequency of your radiochemistry sampling for a) iodines (I-131 and I-134) and b) strip gases (Xenons & Kryptons) (i.e. Daily, 2/week, weekly, monthly) 4. Please feel free to add any other comments you feel is pertinent. Anthony (A.R.)

Fuel Pool Fuel Movement
by aburger＠firstenergycorp.com 03 Feb '10

03 Feb '10

Please provide a response to the following question from the Beaver Valley Refueling Engineer related to movement of fuel assemblies in the Fuel Pool. Austin H. Brunner Jr. - brunnera(a)firstenergycorp.com Does your utility use a non-operator (a mechanic or other type of technician) to move fuel within the Fuel Pool? Since this is not a core alteration, FENOC BVPS does not require a SRO to move this fuel. We have previously used a Westinghouse Fuel Handler or an utility licenced operator to move fuel, since they have a thorough understanding of reactivity and the implications of moving fuel on reactivity. NSSS Vendor Fuel Handler __________________ Utility licenced operator _____________________ Utility non-operator (a mechanic or other type of technician) ________________________ If a non Westinghouse Fuel Handler or an utility operator is used, can you tell me what are your training requirements for the position? ----------------------------------------- The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.
