r LGS FSAR The entire panel assembly is mounted in a cradle on
(
isolation springs such that vibration-induced loads will not affect the performance of the instrumentation.
Also, no items that are critical to the operation of the diesel under emergency conditions are housed within this enclosure.
f.
DC control relay and terminal box -- The following relays are found in the relay and terminal box located at the generator end of the skid:
1.
Emergency start relays 2.
Normal start relays 3.
Other control relays 4.
Coolant temperature high switch 5.
Coolant pressure low switch
6.
Lube oil temperature high switch 7.
Lube oil pressure low switch 8.
Alarm relays The relay and terminal box is mounted at the generator end of the skid.
The box is not mounted on an isolation spring; however, the box is anchored to the skid at its base and supported at the top by two lengths of angle iron.
- meAOA +
(
The above described methods of mrunting have been the manufacturer's standard design for over 20 years.
Neither the manufactprer nor the applicant, whose Peach Bottom units have been in service for about.10 years, have reported any vibration-induced failures in the components mounted on the diesel generator skid.

The response to Question 430.9 lists the other nuclear generating stations where similar diesel generators are in use.
