1. Does your Reactivity Management Committee (or equivalent) routinely have the System Engineers of Reactivity Related Systems discuss system health or reactivity impact at committee meetings?
We monitor the RM-related health of all high-impact systems on the RM Health Report. (This similar to a system health report, but is updated quarterly, regardless of its color/health level.) If we notice an emerging, negative trend with respect to a particular high-impact system, we will have the system engineer attend either the working group level meeting or the upper management level meeting (or both if necessary.)
We've also started maintaining a "Top Five RM Equipment Issues" List. This list contains the five systems that have most negatively affected Reactivity Management in the past trimester. It is screened by upper management every trimester. Pending actions on each system, emerging trends, and total PIP/CR count are typically listed on this list to encourage any needed management action.
2. How often are these discussions? (i.e. after an event, periodically only if the system had several events, or periodically no matter what)
Typically any time a negative trend is discovered, or after repeat failures.
3. Do you have a templete for these discussions that would assist the system engineer in the preparation of the discussion or guide the discussion during the meeting?
No, the system engineer is typically addressing a particular concern or problem. They may bring their system health report (standard template) or parts of it to help with the discussion.
4. What specific topics are discussed? (i.e Reactivity related CRs for system, system health, etc.)
Specific problems with the system, current modifications, pending modifications that may need management sponsorship, outstanding work orders, or anything that the group feels pertinent.
5. What follow up actions does the Reactivity Management Committee take as a result of these discussions?
Working level group may raise concern to upper management level, set up a follow up meeting between affected parties, write an emerging trend PIP/CR, ask system engineer to do more research for follow up meeting, or put their system on the "Top Five List" if warranted.
