RE: [Respvr] CIPS / AO Help
by Mcinvale, James B. 06 Feb '06

Mike, We at Callaway have often see evidence of crud release from fuel following control rod exercises. Some others have as well, and I believe that the EPRI RFP, Working Group 1 on AOA/CIPS did a little looking into it, but never resolved what actually caused the crud release (i.e. local clad temperature changes, etc.) Did RCS activity trend up, or did chemistry samples indicate a spike in Ni, Co or Fe? Back in our AOA cycles, we would sometimes see an increase in AO (a temporary slight AOA recovery) following these exercises. I can't prove it, but I think it was due to release of Boron with the crud that was dislodged from the fuel. How do your AO trends for the cycle look, and how do they compare to predictions? Was there an unexpected shift negative early in the cycle (i.e. 4-6 GWD/MTU?)

First of all, we insert each bank 12 steps, then withdraw to 235 steps, reset the group demand counters to 230, then insert to our full out position. Following this test, delta flux trended up and peaked about 0.6-07% higher than the start. Tavg also was about .2 deg higher as well. The delta flux response was seen fairly equally on all the NIs and a flux map confirmed incore AO was close to excore. We are not used to seeing this at Surry. I am postulating that a group of rods was partially (~ 2 steps) inserted or that this may possibly be CIPS? Has anyone experience this? Any feedback would be appreciated. Michael J.

Manual Trip going into Refueling Outage
by POHL, MATTHEW H 02 Feb '06

02 Feb '06

Fort Calhoun is considering performing a manual reactor trip at 20% power (Turbine Trip is actually at 15%) when coming down for our fall outage... This would save us approximately 2 to 4 hours of critical path. If you currently perform (or can perform) this type of technique or have/had experience with this, please provide me a point of contact or any related information or opinions. Thank you in advance, Matt Pohl Principal Reactor Engineer - Operations Fort Calhoun Nuclear Station (402)533-6820 (work) (402)561-3864 (pager) <p class=MsoNormal><span style='font-size:8.5pt'>This e-mail contains Omaha Public Power District's confidential and proprietary information and is for use only by the intended recipient.

See responses below. I did receive both your emails. Kevin Elam may also have responded for Byron. I hope we agreed with our answers. -Ron Niederer Byron Reactor Engineering Exelon 815-406-3443 ronald.niederer(a)exeloncorp.com -----Original Message----- From: respvr-bounces(a)retaqs.com [mailto:respvr-bounces@retaqs.com] Sent: Friday, December 09, 2005 9:19 AM To: respvr(a)keffective.com Subject: [Respvr] Common Standards PWR RE supervisors I have a major Integration effort coming up for Dominion in regard to reactivity management. Some general questions on Common Standards that we all use. Please let me know what folks do for the following Who performs the 1/M during approach to crit? Operators or REs? RE- Results of 1/M are shared with Op Mgmt before next rod pull Are the RE's an integral member of the team or in an oversite role (review ECCs and 1/M's)? Yes, REs are responsible for 1/M and are consulted with on an on-going basis during start-up. RE also have authority to stop start-up. Who performs the ECC (ECP), RE or the STA or the SRO? 3 signatures on ECC. first (preparer) is RE, second (review) is RE or NSO, third is SRO Who reviews the ECC, (ECP), RE or the STA or the SRO? See above How many people HAVE to review the ECC? 3, including the performer. Does Ops assign a reactivity management SRO to major reactivity changes (SU, maneuver up and down, 75% and back to 100%???? Yes, for major- SU, SD, non-routine (ramp to 30% and return). Routine TVGV- no RM SRO Are all Rx start ups IPTE's (Infrequently Performed Test or Evolutions)? Start-ups from refueling are. Mid-cycle start-ups don't have to be. They are HLAs, though How many plants have pre-developed reactivity plans (ReMA's) in the control room for rapid downpowers? Both Byron units How often are they updated? ~monthly. Can go a little longer when boron concentration is not changing rapidly. Are recurring work orders "flagged" electronically to alert the operators to evolutions that may impact reactivity management? All work is screened for RM impact 2-3 weeks before activity and coded as RM is appropriate. Also, need for ReMA would also be identified at that time. Does RE and Ops meet after RM evolutions for a post job critique? Not necessarily. Ops may or may not include RE in post-job critique. However, RE performs a critiques of most power maneuvers. If so, for all power maneuvers, only major ones (i.e. 0-100%)??? Most are considered. Thanks in advance for your help in this regard. I will gladly share all info with you once I compile it. regards Hugh McKenney Dominion Resources Services, Inc.
