DISCUSSION Two smoke detectors are located in the control room HVAC intakes, but the detectors are not electrically separated. Additionally, isolation of the Control Room due to elevated smoke levels is accomplished manually.

The program esta)lishes policy for the protection of structures, systems, and components important to safety and conforms to the technical requirements in BTP CHEB 9.5-1, Section C.1. The staff finds that the fire protection program meets the guidelines of BTP CMEB 9.5-1, Section C.1, and is,~therefore, acceptable.

Fire Hazards Analysis The applicant's fire hazards analysis enclosed with the letter dated August 15, 1984, identified combustible materials in fire areas, identified safety-related eauipment, determined the consequences of a fire on safe shutdown capability, and summarized available fire protection in accordance with BTP CHEB 9.5-1, Section C.1.b.

DISCUSSION Fire Protection Report and the FSAR discuss the Fire Protection Program.

SSER 12 SECTION 9.5.1.1, page 9-4 DESCRIPTION General Design Criterion (GDC) 3 requires that fire fighting systems be designed to ensure that rupture or inadvertent operation does not significantly impair the safety capability of structures, systems, and components important to safety. To satisfy this requirement, the applicant I has designed components required for hot shutdown so that rupture or inadvertent operation of fire suppression systems will not adversely affect the operability of these components. Where necessary, appropriate protection is provided to prevent impingement of water spray on components required for hot shutdown. Redundant trains of components that are susceptible to damage from water spray are physically separated so that manual fire suppression activities will not adversely affect the operability of components not involved in the postulated fire.

DISCUSSION Hot standby is the design basis for CPSES inadvertent operations evaluation. ,

Attachment to TXX-88430 April 29, 1988 Page 7 of 38 SSER 12 SECTION 9.5.1.4, page 9-6 DESCRIPTION The heating, ventilation, and air conditioning (HVAC) penetrations of fire-rated barriers are provided with UL-labeled fire damper assemblies that have ratings commensurate with the fire ratings of the walls in which they are installed. The fire dampers are installed according to the manufacturer's directions, with the exception of 61 heating and ventilation dampers identified in the fire hazards analysis on Drawing FHA 2 through FHA 48.

DISCUSSION Essential fire dampers are being replaced with qualified assemblies including deviated openings.

REFERENCES See letter logged TXX-6728 dated October 2,1987. TXX-6728 supercedes comments in TXX-6376.

Attachment to TXX-88430 April 29, 1988 Page 8 of 38 SSER 12 SECTION 9.5.1.4, page 9-7 DESCRIPTION The staff finds that although the watertight and missiie- thd bullet-resistant doors are not 3-hour-fire-rated doors, because of the low to moderate fuel loading and fire protection provided, they provide an equivalent level of protection for the areas where they are installed. On the basis of the above review, the staff concludes that with the acceptable deviation, the fire door provided meet the guidelines in Section C.5.a of BTP CHEB 9.5-1 and are, therefore, acceptable.

DISCUSSION Additional deviations have been identified for Door and Damper Assemblies.

-Attachment to TXX-88430 April 29, 1988 Page 9 of 38 SSER 12 SECTION 9.5.1.4, page 9-7 DESCRIPTION Thermal insulating materials are noncombustible. Interior walls and structural components, radiation shielding materials, and soundproofing and interior finishes are noncombustible or are listed by a nationally recognized testing laboratory, such as Factory Mutual (FM) or VL, as having a flame spread of 50 or less in their use configuration, with the exception of redwood trim backed with ' fire-retardant-treated pine in the control room. The trim is-a small quantity of wood that constitutes an insignificant contribution to the control room fuel loading. The trim is exposed and visible to personnel continuously manning the control room. Because of the small quantity of wood and its configuration in the control room, the staff finds the installation of

- the redwood trim an acceptable deviation.

DISCUSSION Wood trim has been deleted from the Control Room.

On the basis of its evaluation, the staff concludes that the installation of the transformer meets the guidelines of BIP CMEB 9.5-1, Sections C.5.a(12) and (13), and is, therefore, acceptable.

DESCRIPTION The computer program product is used in conjunction with the safe shutdown logics to identify components that provide a safe shutdown path. After identifying fire-safe-shutdown-related components (i.e., equipment, trays, conduits, and cables) by fire area, the applicant performed an interaction study to locate the fire areas where redundant paths are not properly separated. The interaction study was done by field walkdowns.

DISCUSSION Clarification - the methodology of the study is as given in the Fire Protection Report, Revision 1.

DESCRIPTION The applicant has provided a fixed emergency communication system that is independent of the normal plant communication system at preselection stations.

A portable radio communication system has been provided for use by the fire brigade. The portable radio communication system includes hand-held portable radios which are powered by rechargeable batteries. A preoperational test will be conducted to ensure that the frequencies used for portable connunication systems will not affect the actuation of protective relays.

Fixed repeaters are used and they are protected from exposure to fire damage.

The staff concludes that two-way voice communication meets the guidelines of BTP CMEB 9.5-1, Section C.5.g(4), and is, therefore, acceptable.
