For Seabrook,

1: All plans require Shift Manager approval.

2: No specific thresholds for plan revisions. The need for a revision will generally be driven by the impact of the change on the original plan.

To: pwrrm@retaqs.com cc: Subject: [Pwrrm] Reactivity plan approval and revisions/ramp rate alarm

SOER 07-01 recommendation 3 stated that "plans for significant reactivity changes are reviewed and approved by appropriate station and shift operations management..." and "If plant conditions delay power changes, the reactivity plan is revised to meet the new plant conditions and approved by management".

Does anyone have specific thresholds for:

1) the level of review a plan requires (such as <10% requires shift supervision, >10% requires shift management, >50% requires station management)

or

2) when a reactivity plan must be revised (such as > 1 hour delay, rods > 10 steps from the predicted value, current power level step >2% from predicted)

Additional question

How do other stations incorporate any ramp rate restrictions that may apply? (Ramp rate alarm, operator training, ramp plan)

Thank you.
