2. Struthers-Dunn 219NE series relays with degraded' magnetic vinyl plastic bearing pad material will be replaced as soon as possible within.the Hope Creek work week schedule.

Replacement will be complete before the end of Hope Creek's seventh refueling outage.

3. Normally energized Struthers-Dunn 219NE series 120 VAC (model number 219BBX222NE) and 24 VAC (model number 219BBX232NE) relays with nc bearing pad or with non-degraded magnetic vinyl plastic bearitg pad material will be inspected to verify no degradation. The results of this inspection will be assessed to determine the need for additional inspections until the relays are replaced. This activity will be completed by j August 29, 1997.
4. The SSWS vacuum breaker relays that were omitted from the EQ Program have been added to the program and will be replaced before the end of their qualified life (November 24, 1997).
