It is our position, as stated in Section 4C.c(a) of Appendix A, that fire

. . stops be installed every 20 ft. along horizontal cable reutings in. areas that are r. t protected by automatic fire suppression systems (AF55).

Vertical cable r utings shculd have fire s: cps installed a each ficor/

ceiling level. Between levels or in vertical cable chases, fire stops snould be installed at the mid-height if the vertical run is 20 ft, or more but less than 30 ft. or at 15 ft. intervals in vertical runs of 30 ft.

cr more unless such vertical cable routings are protected by AFSS directed on the cael'e trays. Incividual fire stop designs shcuid prevent the propa-ga:icn of a fire for a minimum period of 30 min, when tested fcr the largest numcer of cable routings and maximum cable density. Revise your design -

accordingly.

5. page 9.5-5, Fire and Smcke Cetec:icn and Alarm System You state that the fire and smoke detection system is pcwered by the non-class lE de system which is backed by a battery :harger supplied frcm ne emergency power su; ply. This arrangemen; is unacceptable. It is cur position, as stated in Section E.1.(a) of Appendix A, that primary and secondary power supplies should be proviced for the fire detection sys:em ,

Revise your design accordingly.

6. Page 9.5-6a ' Safety Evaluation Two)

You state that in most areas of high fire loading, a backup system will be available in case of failure of the primary suppression system in a given area. However, the backup system is a portable extinguisher or a hose station.

It is our position, as stated in Section E.3(d) of Appendix A, that portable extinguishers, due to their limited capacity and effectiveness, are not con-sidered as secondary protection. Hose stations should be provided so that all areas of the plant can be properly protected. Revise your design accord-ingly. ,

10. Page g.5A.2g You state tha: the Halen system is designed t: maintain a 5 percent minimum c:ncentrati:n at the ceiling f:r 10 minutes. This system design is unacceptable.

to a safe 1ccati:n. Aisc, hose stations should be provided for secondary pre:ecticn for the diesel genera:Or area in case of 1

.t is our position, as stated in Section D2(b) of Appendix A, that gas cylinder storage ,

locatiens should not be in areas that c:ntain or ex;cse safety-related equipment:rthefireprotectionsystemsthatserhethesesafety-related areas. A permit system should be required t: use this epuipment in safety related areas of the piant. In addition, storage locations shculd be chcsen to permit fire pr0tecticn by autcmatic sprinkler systems. Local hose staticcs and pertaole equipment shculd be provided as backup. Revise your design accordingly.

This does not mean that in some instances, such as the cable spreading room, relay room, and 460V and 416V switchgear rooms, redundant trains separated by more than 20 ft will not require additional i

30. The response to item 43 indicates that the review and audit program of of the A/E's QA organization does not extend to fire protection. As indicated in Mr. Va,ssallo's letter of August 29, 1977 and the "For l Comment" editions of Regulatory Guide 1.120, it is our position that the I I

A/E's QA organization should verify the effectiveness of the A/E's QA l program for fire protection through review, surveillance, and audits.

This is in addition to supervisory controls by the A/E and audits by others. Revise the response to item 43 accordingly.

31. State whether the nonconformance control program and corrective action program for fire protection, described in the A/E's Project Engineering Procedures, meet Sections 17A.l .15 and 17A.1.16 of the SNUPPS PSAR.

If not, list and justify the deviations.

ENCLOSURE 2 Fire Protection Review Plant Specific Portions of SNUPPS Plants Callaway Plant

1. The resprnse to Item 2 in the Callaway submittal is not clear. While providing a general commitment to selected portions of the overall QA program as described in Chapter 17 of the Callaway PSAR Addendum, the submittal then limits the commitments such that the general commitment appears meaningless. With respect to the site-engineering activities, the application of part 17A of the Callaway PSAR Addendum is not clear. With respect to the construction activities, the application of part 17B of the Callat ay PSAR Addendum is not clear. Finally, the limiting commitments still do not appear to be completely respon ive to Mr. Vassallo's letter of August 29, 1977. Clarify these points.

2. The response to Item 3 in the Caliaway submittal is not satisfactory. Our I

question related to the offsite responsibility for the Fire Protection Program.

Therefore, indicate the offsite upper level management position that has the responsibility for the Fire Protection Program.

Wolf Creek Plant-

1. The response to Item 2 in the Wolf Creek submittal is not clear. While pro-viding a general commitment to selected portions'of the overall QA program as describ_ed in Chapter 17 of the. Wolf Creek PSAR Addendum, the submittal then limits the commitments such that the general commitment appears meaningless.

With respect to the site-engineering activities, the application of part 17A of the Wolf Creek PSAR Addendum is not clear. With respect to the construction activities, the application of part 17B of the Wolf Creek PSAR Addendum is not-clear. Finally, the limiting commitments still do not appear to be completely responsive to Mr. Vassallo's letter of August 29, 1977. Clarify these points.

Sterling Plant

1. The response to Item 1 in the Sterling submittal states: "Certain portions of procedures covering review, audit, and surveillance oy QA personnel are not considered necessary and are therefore excluded from implementation."

Clarify and justify the extent of the exc,lusions from the Rochester Gas and Electric Corporation's review, audit, and surveillance procedures. Also the omission of QA provisions from procurement documents for fire protection should be compensated for by some oti,er action such as verification of quality by ensite receipt inspection and further cualification by site testir.g. '

Provide such a commitment.
