Please respond to pwrrm@retaqs.com
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. Please let me know what folks do for the following
Who performs the 1/M during approach to crit? Operators or REs? RE.
Are the RE's an integral member of the team or in an oversite role (review ECCs and 1/M's)? RE's considered integral member of team.
Who performs the ECC (ECP), RE or the STA or the SRO? RE.
Who reviews the ECC, (ECP), RE or the STA or the SRO? RE.
How many people HAVE to review the ECC? RE performs, RE reviews, SRO signs it when he/she receives it. RE Supervisor Approves procedure prior to submittal to document control for records retention.
Does Ops assign a reactivity management SRO to major reactivity changes (SU, maneuver up and down, 75% and back to 100%???? 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? We issue pre-developed ReMA's.
How often are they updated? Every 1000 MWD/MTU. More specific plans are issued when requested.
Are recurring work orders "flagged" electronically to alert the operators to evolutions that may impact reactivity management? No.
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 normally.
Thanks in advance for your help in this regard. I will gladly share all info with you once I compile it.
