Surry Operations and Reactor Engineering departments are performing a Self
Assessment on our Reactivity Management program this week. We would like
to include some industry benchmarking in this Self Assessment and would
greatly appreciate your responses to the following questions. If possible,
respond with your replies within the next 2 days to James_Shell(a)dom.com
1. How are your station’s reactivity management expectations
communicated? (i.e. admin procedure, operations procedure, etc…)
2. How are expectations that are outside of the standards
communicated/controlled/decided? (i.e. accepted practices not specifically
in your standard)
3. What are the expectations for SRO’s/Unit Supervisors/Reactor
Operators/Reactor Engineers during routine and non-routine manipulations?
(i.e. during daily dilutions to what extent is each party involved?
If the shift needed to dilute 50 gals more than predicted who would be
involved? Is the Reactor Engineer involved with any normal reactivity
manipulations (dilution/ changing cooling water flow that could potentially
affect letdown IX temp, etc….))
4. Is there extra oversight in the main control room during reactivity
manipulations (i.e. an extra SRO/US?)
5. When would the shift contact you regarding reactivity issues?
6. Does your station peer check routine reactivity manipulations and can
the SRO/Unit Supervisor or the STA be this peer check?
7. What is provided to operations for planned and unplanned unit
maneuvers?
8. Do you have any planned interaction with operations regardless of
what events are scheduled (i.e. briefing at some interval on reactivity,
etc…)
9. Are you involved in your Licensed Operator Initial or Continual
Training programs in any way? (New core, periodic during cycle, etc...)
10. When would a planned ramp also be practiced on the Simulator first?
11. Would you be involved and present in support of this Just-In-Time
training for ramping (for one shift, all shifts, etc…)
12. Does your Operations shift or STAs have the tools available to model
required dilutions/borations and rod positions for emergent ramps when
Reactor Engineering is not onsite?
13. How tight does your delta flux control need to be during ramps? Are
you a CAOC or RAOC plant?
Thanks for your time,
Jim
