Who performs the 1/M during approach to crit? Operators or REs? REs Are the RE's an integral member of the team or in an oversite role (review ECCs and 1/M's)? Integral member of team Who performs the ECC (ECP), RE or the STA or the SRO? By procedure, any Qualified RE or Licensed Operator. In practicality, REs. Who reviews the ECC, (ECP), RE or the STA or the SRO? RE reviews How many people HAVE to review the ECC? In addition to performer and reviewer, SRO approves Does Ops assign a reactivity management SRO to major reactivity changes (SU, maneuver up and down, 75% and back to 100%???? Typically, yes Are all Rx start ups IPTE's (Infrequently Performed Test or Evolutions)? Yes How many plants have pre-developed reactivity plans (ReMA's) in the control room for rapid downpowers? Turbine Runback to ~60% at 25%/min Fast Ramp to ~64% at 100%/hr Ramp Offline at 25%/hr Ramp Offline at 15%/hr Generic Ramp down to any power level down to 25% at a rate of 15%/hr to 25%/hr and a hold at reduced power anywhere from 4 hrs to 12 hrs and a subsequent ramp back to full power (This is a host of curves for rod position, boration, and dilution amounts) (Special ReMA's depending on pending activities) How often are they updated? ~monthly (~100 ppm change in RCS boron concentration) Are recurring work orders "flagged" electronically to alert the operators to evolutions that may impact reactivity management? Yes Does RE and Ops meet after RM evolutions for a post job critique? No, but Ops is supposed to perform an internal post job critique. Then REs prepare a written critique which is posted. If so, for all power maneuvers, only major ones (i.e. 0-100%)??? For all power maneuver that I have time for. (In other words, if I am not too busy, I would prepare a critique for all ramps. I have missed a several.) Kevin S.

Reactivity Management Standards

Reactor Engineers 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.

New Fuel Receipt Questions
by mlaris＠firstenergycorp.com 02 Dec '05

02 Dec '05

FENOC is trying to develop a standard fuel receipt process between BWRs/PWRs. To that end, I have some questions on how fuel receipt is done at your plants: 1. What role, if any, does Quality Assurance or Quality Control play in the fuel receipt process? Specifically, do they perform any inspections, review paperwork, etc? 2. What is the purpose the new fuel inspection activity? Is the new fuel receipt inspection considered an inspection for "shipping or handling damage" or it is a traditional receipt inspection? 3. Who does “inspection” (i.e. Reactor Engineering, QA/QC, Maintenance, shared resources, etc.)? 4. What specific role(s) does Rx Engineer perform? 5. Who unloads shipping containers? 6. Does your plant utilize the same process for fuel receipt at the site as other procured material? 7. Does your plant require the fuel receipt personnel to be ANSI/ASME N45.2.6 qualified, and at what level? If not required to be qualified to the N45.2.6, why not? Once I compile this data, I'll send it out to everyone.

RE: Initial draft of the PWR equivalent for Reactivity Management Event Classification
by POHL, MATTHEW H 07 Nov '05

Morning Jaime... What a HUGE effort you put forth to combine this data..!! This looks like a great start and I'll be happy to give my two cents... I'm rewriting my RM Standing Order and these examples will already clear up some of the gray areas we were looking at... THANKS AGAIN!!!
