                              Attachment A



The following items represent the commitments that the Public Service

Electric and Gas Company is making to the Nuclear Regulatory Commission

relative to LER 354/97-007-00:



1.   Panels containing Struthers-Dunn 219NE series relays with degraded

     magnetic vinyl plastic bearing pad material are being inspected

     weekly to ensure continued operability until the relays are

     replaced.



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 no

     bearing pad or with non-degraded magnetic vinyl plastic bearing 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 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).



5.   Normally energized Struthers-Dunn 219NE series 120 VAC (model number

     219BBX222NE) and 24 VAC (model number 219BBX232NE) relays with no

     bearing pad or with non-degraded magnetic vinyl plastic bearing pad

     material will be replaced before the end of their calculated service

     life (April 15, 1998).
