.t.l SUPPLEMENT TO THE FIRE PROTECTION SAFETY EVALUATION REPORT IN THE MATTER OF CONSUMERS POWER COMPANY PALISADES PLANT DOCKET NO. 50-255 3.2.l Cable Penetration Firestop Qual1fication Our SER noted that the licensee would provide results of tests to demonstrate the ability of existing and new cable penetration firestop designs to prevent propagation of a severe fire equivalent to an ASTM E-119 exposure fire.
By letter of September 29, 1978, Consumers Power Company prov1ded results of testing of various cable penetration firestop designs. Although these tests were not performed with a s1gnif1cant pressure d1fferential across the seal with the hfgher pressure on the exposed ~1de, we find that such conditions would ~ot affect the ab111ty of these firestops to withstand a severe fire.
We have reviewed th1s test data and find that these tests demonstrate the ab111ty of the tested firestop designs to withstand an ASTM E-119 3-hour exposure fire.
Based on these results, we find that the tested firestop designs satisfy the prov1s1ons of Append1x A to BTP9.5-l and are therefore acceptable,*
As noted 1n Sect1on 3.1.3, the H:censee has comm1tted to install and upgrade cable penetrat1on firestops that are cons1stent w1th the tested des1gns~ Accordingly, this 1tem has been satisfactorily resolved.
3.2.2 Administrat1ve Controls Responsibility for comp1et1ng the review of the licensee's admini-strative controls for fire protection and resolving this item was transferred to the Office of Inspection and Enforcement.*
3,2,3 Techn1cal specifications Our SER noted that technical specifications would be developed for those components upon which primary reliance is placed to achieve safe shutdown in a fire situation and which are presently not required by technical specifications. This concern was identified in reviewing certa1n of the 1nitial details for the proposed alternate shutdown system.
These deta1ls indicated that certa1n equipment not required to be operable by technical

specifications may be used for the alternate shutdown system.
Subsequently the review of the alternate shutdown system has
~
been deferred to the Systematic Evaluation Program (SEP).
This review will assure that our position, including required technical specifications, is satisfied. Accordingly, this item is acceptably resolved for those areas that rely on the alternate shutdown system.
Additionally, the licensee has reviewed the fire hazards analysis to assure that primary reliance to achieve safe shutdown is only placed on equipment that is required to be operable by the technical specifications.
By letter of September 29, 1978, the licensee provided the results of this review which indicated that existing technical specifications adequately address the operability requirements of equipment required to achieve and maintain safe shutdown, with the exception of the specifi-cations on the auxiliary feedwater system.
The existing technical specifications require as a limiting coordination for operation that only one auxiliary feedwater pump and one fire pump be operable to provide a supply of feedwater to the steam generators.
The licensee has indicated that these specifications will be revised to the Standard Technical Specifications (STS); however, this may not occur for some time.
Until these specifications are upgraded to the STS, if a fir~
were to occur that caused loss of the only operable auxiliary feedwater pump, *the fire pump may not have sufficient capacity to satisfy both fire protection and feedwater demands.
Accordingly, the licensee proposes to revise technical specification 5.l~a to require operability of both auxiliary feedwater pumps.
Subject to issuance of such a specification, this item is satisfactorily resolved.
3,2,4 Fire Brigade Our evaluation on the minimum required fire brigade shift size was sent to the licensee by letter of September 7, 1979.
Additionally, this requirement is now incluoed 1n Appendix R to 10 CFR Part 50 which will become effective in the near future.
We, therefore, expect that the licensee will conform to this requirement. Subject to conformance to this requirement, this*
item 1s satisfactorily resolved.

Non-Approved Components Our SER noted that certain f1re detectors were being used in the fire detection system that were not approved by a recognized testing laboratory.
By letters of July 28, 1978 and September 15, 1978, the licensee 1nd1cated that fire detector spacing and location w111 be in accordance w1th NFPA-72E, "Automatic Fire Detection." Although 1n certain locations photo-electric type detectors are being used that are not approved by a recognized testing laboratory, we f1nd that sufficient other type detectors that are approved by a recognized testing laboratory will be used to afford prompt detection capability.
We find that the fire detection system satisfies the guidance contained in Section 2.0 of our SER and is therefore acceptable.
