CORRECTIVE ACTIONS
Training Request 2017-0098 was written for the License Requalification program and the Initial License Operator program to present the new guidance for declaring a CCW train inoperable when ESW cannot be aligned for makeup from the Control Room. Essential Reading 2017-013 was issued for licensed personnel.
TS Bases 3.7.7 will be revised to state that if emergency makeup from ESW is unavailable, then the CCW train is inoperable. This action is being tracked by Condition Report (CR) 111808.
SAFETY SIGNIFICANCE
The safety significance of this event is very low. The "B" CCW train was available during the time the "A" train was inoperable. In addition, the "A" train CCW was functional and in operation during the event.
OPERATING EXPERIENCE/PREVIOUS EVENTS None. Page 3
