1.0 PURPOSE
[ _
The purpoce of this procedure is to restore RPV water level to above top of active fuel.
2.0 ENTRY CONDITIONS Enter this procedure from SP 29.023.01 (Level Control) or SP 29.023.02 (Cooldown) when RPV uater level cannot be maintained above top of active fuel (TAF = +6" as 4
read on fuel zone instrunentation L1-007).
