This is a resend from an email I sent Friday, Dec 9th
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 performs the 1/M. Ops performs a backup.
Are the RE's an integral member of the team or in an oversite role (review ECCs and 1/M's)?
Integral member.
Who performs the ECC (ECP), RE or the STA or the SRO?
RE performs the ECP calculation.
Who reviews the ECC, (ECP), RE or the STA or the SRO?
Another RE does an independent review of the ECP.
How many people HAVE to review the ECC?
Approval is done by the SM. Ops procedures requires a license holder to perform a second ECP to validate the one being used.
Does Ops assign a reactivity management SRO to major reactivity changes (SU, maneuver up and down, 75% and back to 100%????
No
Are all Rx start ups IPTE's (Infrequently Performed Test or Evolutions)?
No How many plants have pre-developed reactivity plans (ReMA's) in the control room for rapid downpowers?
Seabrook has pre-developed reactivity plans for rapid downpower.
How often are they updated?
Monthly.
Are recurring work orders "flagged" electronically to alert the operators to evolutions that may impact reactivity management?
In theory yes, but we need to make improvements in this area.
Does RE and Ops meet after RM evolutions for a post job critique? If so, for all power maneuvers, only major ones (i.e. 0-100%)???
Not typically.
Thanks in advance for your help in this regard. I will gladly share all info with you once I compile it.
