Question on SOER 07-01 Reactivity Management
by Fago, Carl D 04 Oct '07

04 Oct '07

I'm looking for some info on how everyone else is addressing the simulator training recommendation in the subject SOER. Specifically, the bullet in the recommendation says: Reactor Engineers participate in simulator training with shift operating crews at least once per refueling cycle or at least once every two years. Will your site credit Just In Time Training (JITT) opportunities to meet this or just simulator scenarios as part of the Operator Training program? I'll compile individual results and send it out for everyone. Thanks, Carl Carl D. Fago Reactor Engineering Supervisor Oconee Nuclear Station Duke Energy 864-885-3047 cdfago(a)duke-energy.com

RIS 2007-021 Compliance

Question to Reactor Engineering Supervisors with respect to RIS 2007-021. What type of time averaged values are used in your calorimetric program (e.g. 1 minute average, 5 minute average, etc)? What type of time averaging is used for either feed flow or steam flow which feeds your calorimetric program? Which of the time average calorimetric values are used to ensure compliance with your licensed thermal power limitations and the intent of RIS 2007-021? Have you made changes to your calorimetric procedures or methods as a result of the RIS? Is "Steady State" in reference to licensed thermal power defined at your plant? Michael J.

RIS 2007-021 Compliance

Here are FCS's answers 1) What type of time averaged values are used in your calorimetric program (e.g. 1 minute average, 5 minute average, etc)? FCS uses a 10-minute average as the value used to monitor reactor power and compliance. There are other averages available for trouble-shooting and for information (real time calculate every 30 seconds, 2-minute average, 5-minute average, and others up to 8 hour averages) 2) What type of time averaging is used for either feed flow or steam flow which feeds your calorimetric program? FCS has implemented a 2-minute average for Feedwater and S/G Blowdown flow. 3) Which of the time average calorimetric values are used to ensure compliance with your licensed thermal power limitations and the intent of RIS 2007-021? FCS uses a 10-minute average as the value used to monitor reactor power and compliance. 4) Have you made changes to your calorimetric procedures or methods as a result of the RIS? FCS has interim guidance not to exceed the license limit of 1500 MWth while at steady state conditions, with a target band of 1497-1499 MWth. We also clarified the term steady-state with respect to the rotation of secondary equipment. (we have 3 Main Feed, 3 Condensate and 3 heater drain pumps). The 10-minute average for secondary calorimetric would indicate a ~5-6 MWth increase during the start of the standby feed pump, and then return to normal once the running pump is secured. We have told the SRO/RO's to declare the calculation invalid and rely on NI and delta-T power during this timeframe. (It usually takes 10-12 minutes to settle back out). 5) Is "Steady State" in reference to licensed thermal power defined at your plant? YES J. E.
