Dear Mr. Holmes:
This is to provide information you requested of Ms. I. Netzel of the Zion Station staff and myself on November 25, 1987, regarding emergency lighting.
As documented in NRC Inspection Report Nos. 50-295/85-011 and f
50-304/85-012, CECO committed to perform a "verification walkdown" following completion of emergency lighting modifications to verify that the modifications had achieved their objective of providing sufficient illumination. That walkdown has been completed and has identified the need for some additional lighting.
Installation of this additional lighting is expected to be completed by August, 1988. As described in the attached evaluation, interim compensatory measures will remain in place which will provide an equivalent level of protection until the installation has been completed.
As you know, completion of emergency lighting and other fire protection modifications has been the subject of a schedular exemptiori request still pending at NRR. We will advise NRR of this latest information on emergency lighting for inclusion in the exemption.
If there are any questions regarding this matter, please contact me, Very truly yours, 8807120092 880706 a

EMERGENCY LIGHTING EVALUATION PURPOSE The intent of this evaluation is to justify the existing Zion Station emergency lighting capabilities.
EVALUATION As a result of the conclusions of th'e 1984 ~10 CFR 50.48 Appendix R
Reasse:mmen t,
emergency lighting. units have been provided in areas nceded -for operation of saf e shutdown equipment and in access and egress routes.
- However, based upon a past.
modification valkdown of the emergency lighting units with a Zion Station Operator, it was determined that the existing emergency lighting does not. cover all the arcas required to be accessed during safe shutdown.
Additional emergency lighting units are required to be installed to enhance the existing emergency lighting system.
An additional modification has been proposed to install new emergency lighting units by August, 1988.
During the' interim, the plant operators will be provided with miner hats equipped with flashlights.
One miner hat will be provided for each operator and vill be stored just outside the Main Control
- Room, in-the Appendix R cabinet, located on the Turbine deck.
The miner hats and flashlight batteries vill be kept under continuous charge to ensure their operability in case they are needed.
The operators are trained -and experienced personnel.
The operators are familiar with the. entire plant layout.
Each operator has been trained as to the specific duties required to be performed during an Appendix R
fire scenario.
The existing emergency lighting units, coupled with the miner hats and the operators experience, provide reasonable assurance that safe shutdown will be accomplished.

SUMMARY
Based on the above evaluation, the-existing emergency lighting capabilities, for the-interim, will be adequate for the achievement of safe shutdown-during an Appendix R fire scenario for the following reasons:
(1)
Some eme'rgency light'ing-units already exists which will' be enhanced by the additional modification.
(2) 'Each operator will be provided with a
miner's hat equipped with a flashlight.and stored outside the main control room in the fire protection cabinet.
(3)
The operators are familiar with the plant layout and have been trained as to their specific duties.
