ENCLOSURE 1
I EA 0~E TRIP A site trip and an audit drawing review was conducted by Sy Weiss and Om Chopra of EICSB, Division of PWR-A, at the Shearon Harris plant on January 28-30, 1986 to assure that the installation of safety-related electrical equipment was im-plemented in accordance with the design described and the criteria specified in the FSAR.
A.
Plant Walk Throu h
The following areas were observed:
1.
Control-Room 2.
Cable Runs and Cable Spreading Area 3.
Vital Instrumentation and Control Power Supply Installation 4.
ESF Systems and Pump Rooms 5.
Electrical Penetration areas 6.
Battery and Battery Charger rooms 7.
Switchgear rooms 8.
Diesel Generator rooms 9.
Turbine Building 10.
Reactor Building 11.
Auxiliary Shutdown panel 12.
Switchyard B.
Comments 1.
In general, we verified that separation between the redundant divisions or between the Class 1E and non-class lE circuits of the same division is maintained and barriers are provided where separation is marginal.
Where the above could not be accomplished, the applicant insti-tuted a test program conducted by Wyle Laboratories, to provide justification for lesser separation distances.
The test program methodology and the test results have been reviewed and accepted by the staff.
2.
As part of the in-plant observation, we traced control and power cable routes for two redundant Residual Heat Removal pumps from switchgear to the pump installations and control room. It was demonstrated that the minimum separation requirements had been met for the two RHR pumps.
3.
The implementation of identification and color coding schemes for safety-related circuits and equipment was observed.
We found that one of the RHR pumps (for the selected systems observed) was not identified.
The applicant has committed to properl.v identify the above RHR pump and we find this to be acceptable.
- However, we re-quire the applicant to check other equipment to assure this condi-tion does not exist elsewhere in the plant.
4.
During our audit of the battery rooms, we found that the showers in the battery rooms are not enclosed and are very close to the batteries, thereby creating the potential of shower spill causing
e I
h f
k
~ c 4 damage to the batteries.
We require the applicant to either enclose the showers in battery rooms or provide justification for the existing design.
5.
During our audit of the control room alarms provided for dc power
- systems, we found there was only one battery trouble alarm provided for both redundant trains (125V DC Emer.
Bus A/B Trouble).
We re-quire that a separate dc bus trouble alarm for each train be provided to facilitate quick trouble diagnosis of dc power systems.
