PURPOSE The purpose of this calculation is to document the comparison of the existing Oconee Nuclear Station (ONS) Fire Protection Program to the requirements presented in Chapter 3 of NFPA 805. This calculation documents fire protection features needed to protect nuclear safety-related structures, systems, or components which are designated as QA Condition 3 systems. II. BACKGROUND Under its current operating license, Oconee Nuclear Station is required to maintain the provisions of its approved fire protection program. The current licensing basis documents for Oconee are-Appendix A to BTP APCSB 9.5-1 and 1 OCFR50 Appendix R Sections IllI.G, IllI.J, lllL and 111.0. The NRC has added 10CFR50.48(c) as an alternative method of compliance to

  . _0_CF_       R50.be-F                8_(_)_stbeao.tionof       tbe[dstyoassnusstandardNElA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants (2001 Edition). Oconee has elected to transition to 10CFR50.48(c).

As part of the transition to NFPA 805, the fundamental fire protection program design elements are required to be identified. NFPA 805 Chapter 3 defines fundamental fire protection program attributes. This report documents the comparison of the existing Oconee NuclearStation Fire Protection Program to the requirements presented in Chapter,3 of NFPA 805. Ill. METHODOLOGY The requirements presented in Chapter 3 of NFPA 805, 2001 Edition, were compared to the existing Oconee Nuclear Station fire protection program. The attributes of fire protection features and administrative programs that satisfy the provisions of NFPA 805 were documented. In addition where direct compliance was not found, a search of previous licensing and station documentation was conducted to determine if the NRC had previously approved alternative methods of compliance. Where compliance could not be determined, an open item was established. The comparison of the Oconee Nuclear Station fire protection program to Chapter 3 of NFPA 805 is summarized and further substantiated with additional detail and references in Section VI, of this report. Section VI provides the descriptions, including background and discussion, for the compliance basis of each requirement presented in Chapter 3 of NFPA 805. Section VI has three components. The first is the verbatim text of NFPA 805 (provided in italics). The second is a detailed discussion for the ONS compliance basis. The third is a list of references. Attachment A, Compliance Table lists the elements of the fire protection program for transition to the new 10 CFR50.48(c) fire protection license. This table includes the NFPA 805 Code

Calculation No..: OSC-9295 Revision No.: I Applicable Units: Oconee Unit 1, 2, & 3 Page 2 of 85 section and text, the Compliance Statement, and the Compliance Basis. The specific elements of Chapter 3 where required by the deterministic or performance based requirements of Chapter 4 are listed in the B-3 Table of the ONS NFPA 805 Transition Report. The ONS 10CFR50.48(c) Fire Protection Program is bounded by the Power Block as defined in Attachment I of the ONS NFPA 805 Transition Report. The following standard Compliance Statements are used in the Compliance Table:

Comply - Oconee clearly complies with the NFPA 805 requirement, through direct 'literal' compliance or compliance with the intent (e.g. NFPA 805 specifies requirement located in one document and station has it located in another document). Sections may comply and also have, an Area for Improvement which may not submitted in the LAR.
Complies by Previous NRC Approval - Oconee does not clearly meet the NFPA 805 requirement but has been approved directly by the NRC (typically by
Complies by Previous Licensee Evaluation - Oconee does not clearly meet the NFPA 805 requirement but the Licensee has completed an equivalency evaluation.
Submit for NRC Approval - Oconee does not clearly meet the NFPA 805 requirement and will submit the current basis for NRC review and approval.
Further Action Required - Oconee will take an action to revise documentation or perform additional analysis and/or actions to demonstrate compliance.
N/A - NFPA 805 requirement does not apply to Oconee.

Open items are divided into three categories:

1. Submit for Approval

2. Further Action Required,

3. Area for Improvement - Area for Improvement are sections where Oconee is currently in compliance and station documentation will be enhanced forfurther clarification. Areas for Improvement may not be submitted in the LAR.

The comparison utilizes NEI 04-02 "Guidance for Implementing A Risk-Informed, Performance-Based Fire Protection Program Under 10 CFR 50.48(c)," Revision 1 as a tool to determine the method and extent to which compliance is demonstrated. The Compliance Table, showing cross-reference and compliance statements, was based on Table B-1 of NEI 04-02. IV. REFERENCES

SUMMARY

The information is a compilation of how the ONS Fire Protection Program supports each requirement of NFPA 805, Chapter 3. Section 3.1 General This chapter contains the fundamental elements of the fire protection programand specifies the minimum design requirements for fire protection systems and features. These fire protection program elements and minimum design requirements shafl not be subject to the performance-based methods permitted elsewhere in this standard. Previously approved alternativesfrom the fundamentalprotectionprogram attributesof this chapterby the AHJ take precedence over the requirements containedherein.

performance-based methods permitted elsewhere in the standard. The following discussion of Chapter 3 requirements documents ONS compliance or intended compliance with the individual code sections. In addition documentation is provided where previous NRC approval has been granted for a deviation to the code. Section 3.2 Fire Protection Plan 3.2.1 Intent A site-wide fire protectionplan shall be established. This plan shall document management policy and program direction and shall define the responsibilities of those individuals responsiblefor the plan's implementation. This section establishesthe criteriafor an integrated combination of components, procedures, and personnel to implement all fire protection program activities. The Design Bases Specification for Fire Protection, OSS-0254.00-00-4008, documents the ONS Fire Protection Program including management policy, program direction and defines the organization, responsibilities and requirements of involved personnel. Many of these attributes have been updated and revised since original correspondence with the NRC including the January 16, 1978 letter from Duke to the NRC in response to the Nuclear Plant Fire Protection Functional Responsibilities, Administrative Controls and Quality Assurance (FRAQUA) letter and the original and updated Response to Appendix A to Branch Technical Position APCSB 9.5-1. The ONS fire protection program is currently based on, and complies with, the requirements of 10CFR50.48(a). Note that Oconee uses the terminology Fire Plan to represent the fire pre-plan (fire-fighting strategies) for fire scenarios at the site and uses the term Fire Protection Program (per I OCFR50.48) to delineate the implementation of fire protection policies at the plant.

The LPSW system provides water to hose stations within the Reactor Buildings. The LPSW pumps takes suction from the CCW crossover line and discharge to a common discharge header in the same arrangement as the HPSW pump described above. The Keowee Hydro Station Water Spray and Fire Hose systems are suppliedbythe combined Service Water (SW)/Fire Protection Water system. The system is generally supplied via lake head pressure which provides sufficient flow and pressure for most operations. In the event additional flow/pressure is necessary an electric fire pump is provided. A portable gasoline fire pump is also provided in the event the electric fire pump is not in service.

The most demanding water based fire suppression system required for Chapter 4 is the Main Feedwater Pump water spray systems. Calculation OSC-7858 hydraulically determined the water pressure and flow requirements. The results of the calculation determined a required flow of 1,404 gpm at 104.4 psi (including 750 gpm hose stream allowance. The available pressure at the calculated node when flowing 1,404 gpm is 140 psi. This calculation included the shortest flow path out'of service. These demands are all less than the output of one of the HPSW Pumps which is 6,000 gpm at 117 psi. The NRC August 11, 1978 SER Section 4.3.1.2 states "There are two 6,000 gpm HPSW pumps and one 500 gpmjockey pump, all ratedat 117psi net pressure. The two largepumps are consideredredundant,each capable of supplying the largestdesign fire flows plus other simultaneous demands on the HPSW system."

A failure in one tank orits piping shall not allow both tanks to drain. The tanks shall be designed in accordancewith NFPA 22, Standard for Water Tanks for PrivateFire Protection. Exception No. 1: Water storage tanks shall not be requiredwhen fire pumps are able to take suction from a large body of water (such as a lake), provided each fire pump has its own suction and both suctions and pumps are adequatelyseparated. Exception No. 2: Cooling tower basins shall be an acceptable water source for fire pumps when the volume is sufficient for both purposes and water quality is consistent with the demands of the fire service. The HPSW pumps take suction through the CCW crossover header. The crossover header can be supplied from any units CCW intake piping and can be gravity fed from Lake Keowee.

The Keowee Fire Protection Pump takes its suction from Lake Keowee at the spillway wall. The back-up Keowee fire pump is a portable pump which can draw water from the gravity side of the suction piping. Reference(s): NRC SER dated August 11, 1978 Design Basis Specification for Fire Protection Drawing KFD-109A-1.1 "Keowee Hydro Station - Flow Diagram of Service Water System" 3.5.3 Firepumps, designedand installedin accordancewith NFPA 20, Standardfor the Installation of Stationary Pumps for FireProtection, shall be provided to ensure that 100 percent of the requiredflow rate and pressureare available assuming failure of the largestpump or pump power source. The pumps used to supply the fire protection systems at the Oconee Plant are not fire pumps but have been accepted by the NRC. As stated in Section 3.5.1, above, the HPSW System provides water for the fire protection system at Oconee. There are two 6,000 gpm (at 117 psig) HPSW pumps. There is also a 500 gpm (at 117 psig) jockey pump in the HPSW System. The jockey pump normally operates to maintain the system pressure on the fire protection headers and also supplies non fire related loads. In the event of a fire, one 6,000 gpm HPSW pump will automatically provide sufficient water for maintaining fire water demands and elevated water storage tank inventory. The second 6,000 gpm HPSW pump would be available if needed. The LPSW system provides fire water to the Reactor Building hose stations only. The LPSW pumps are rated at 15,000 gpm (at 100 psig) which is more than sufficient for the Reactor Building hose stations. The HPSW jockey pump is not considered part of the required fire protection for NFPA 20. The NRC August 11, 1978 SER Section 4.3.1.2 states "There are two 6,000 gpm HPSW pumps andone 500 gpmjockeypump, all ratedat 117 psi netpressure.

The Keowee Hydro Station has a separate Fire Pump to supply hose stations and fixed suppression systems including the Keowee Main Transformer. The Keowee Fire Pump takes suction from Lake Keowee at the spillway structure. The Keowee Fire Pump is rated at 1,150 gpm at approximately 56 feet of head pressure with a shutoff head of 375 psi. A portable pump is provided and may be used in establishing a backup fire fighting system. Oconee Nuclear Station initiated Problem Identification Program (PIP) 0-99-4487 to evaluate the HPSW and Keowee Fire Water pumps' capabilities. The result of Calculation KC-2135, Revision 8, that was performed for the Keowee Fire Pump concluded that the flow and pressure available'at the Keowee Main Transformer deluge system did not meet NFPA 15-1996 (or -1969 the Code of Record) requirements. {FurtherAction Required - Ensure resolution of the Keowee fire pump replacement (PIP 0 3492) satisfies the requirement of this section.}

        "We find that the fire pumps meet the objectives outlined in Section 2.2 of this report and are, therefore, acceptable."

The 2005 NRC Triennial Fire Protection Inspection identified that the HPSW control circuit could be vulnerable from a Turbine Building Fire. A HPSW Vulnerability Evaluation was performed and is documented in PIP 0-05-4125. The vulnerability study determined that although the potential exists for loss of both HPSW pumps, the postulated fire scenarios that result in loss of the pumps would not affect Standby Shutdown System. In addition, in the event of the unavailability of both HPSW pumps, the EWST can provide a limited quantity of water for fire suppression. Reference(s): NRC SER dated August 11, 1978

             "Smoke detectors in some areasof the plant containingelectricalcable insulationare located lower than the ceilinglevel and,therefore, maynot respondas rapidlyas they would if located at the ceiling. However, since fires in cable insulation generate heavy quantities of smoke, reasonablyprompt detection can be expected. Ionization type smoke detectors are used throughoutthe plant. In some tests, ionizationtype detectorshave not respondedasrapidlyto a fire involving PVC as they do to a fire involving other types of insulation. Tests have shown that they are, however, adequate to detect first in their early stages. To assure that fires in safe shutdown areasof the plant are detected, the licensee has proposed,in addition to the exiting detection system, to provide detectorsin all areas containingsafe shutdown equipment and combustibles. In addition, the licensee has proposed to provide a dedicated safe shutdown system which would be unaffected by fires involving safe shutdown equipmentsuch that the plantcan be safely shut down in the event of a fire in any location in the plant."
             "We find that, subject to the implementation of the proposedmodifications, the fire detection and signalingsystem in conjunction with the safe shutdown system satisfiesthe objectives of Section 2.2 of this report and is, therefore, acceptable." Modifications referenced above including addition of detectors in areas containing safe shutdown equipment and providing a dedicated safe shutdown system have been implemented.

Original deviations to the fire detection system are listed in the Design Basis Specification for Fire Protection and the Design Basis Specification for the Fire Detection System. Modifications to the fire detection system have since been performed. Modifications are performed in accordance with NFPA 72. A major upgrade to the fire detection system was performed under modification NSM-52796 in 1992. Currently the NRC committed fire detection instrumentation devices are listed in SLC 16.9.6.

Calculation No.: OSC-9295 Revision No.: 0 Applicable Units: Oconee Unit 1, 2, & 3 Page 1 of 84 PURPOSE The purpose of this calculation is to document the comparison of the existing Oconee Nuclear Station Fire Protection Program to the requirements presented in Chapter 3 of NFPA 805. This calculation documents fire protection features needed to protect nuclear safety-related structures, systems, or components which are designated as QA Condition 3 systems. II. BACKGROUND Under its current operating-license, Oconee Nuclear Station is required to maintain the provisions of its approved fire protection program. The current licensing basis documents for Oconee are Appendix A to BTP APCSB 9.5-1 and 10CFR50 Appendix R Sections Ill.G, Ill.J, 11.L and 111.0. The NRC has added 10CFR50.48(c) as an alternative method of compliance to 10CFR50.48(b). 10CFR50.48(c) is the adoption of the industry consensus standard NFPA

 -                  8*5-Performance*Based-Standa~rd--fT-PireF-Protection-for-Light-WaterReactur-E-iectric-          .........

Generating Plants (2001 Edition). Oconee has elected to transition to 10CFR50.48(c). As part of the transition to NFPA 805, the fundamental fire protection program design elements are required to be identified. NFPA 805 Chapter 3 defines fundamental fire protection program attributes. This report documents the comparison of the existing Oconee Nuclear Station Fire Protection Program to the requirements presented in Chapter 3 of NFPA 805. Ill. METHODOLOGY The requirements presented in Chapter 3 of NFPA 805, 2001 Edition, were compared to the existing Oconee Nuclear Station fire protection program. The attributes of fire protection features and administrative programs that satisfy the provisions of NFPA 805 were documented. Where direct compliance was not found, a search of previous licensing documentation was conducted to determine if the NRC had previously approved alternative methods of compliance. Where compliance could not be determined, an open item was established. The comparison of the Oconee Nuclear Station fire protection program to Chapter 3 of NFPA 805 is summarized in Attachment A - Compliance Table'and further substantiated with additional detail and references in Section VI, of this report. The compliance table is a brief overview which includes the NFPA 805 Code section and text, the Compliance Statement, and a Compliance Basis summary. Section VI has three components. The first is the verbatim text of NFPA 805 (provided in italics). The second is a detailed discussion of the ONS compliance basis. Finally a list of references is provided. The following standard Compliance Statements are used in the Compliance Table:

Calculation No.: OSC-9295 Revision No.: 0 Applicable Units: Oconee Unit 1, 2, & 3 Page 2 of 84 Comply - Oconee clearly complies with the NFPA 805 requirement, through direct 'literal' compliance or compliance with the intent (e.g. NFPA 805 specifies requirement located in one document and station has it located in another document). Sections may comply and also have an Area for Improvement which may not submitted in the LAR.

                    " Complies by Previous NRC Approval - Oconee does not clearly meet the NFPA 805 requirement but has been approved directlybythe NRC (typically by SER).

Complies by Previous Licensee Evaluation- Oconee does not clearly meet the NFPA 805 requirement but the Licensee has completed an equivalency evaluation.

                    " Submit for NRC Approval - Oconee does not clearly meet the NFPA 805 requirement and will submit the current basis for NRC review and approval.
                    " Further Action Required - Oconee will take an action to revise documentation or perform additional analysis and/or actions to demonstrate compliance.

N/A - NFPA 805 requirement does not apply to Oconee.

Open items are divided into three categories:

1. Submit for Approval

2. Further Action Required

3. Area for Improvement - Area for Improvement are sections where Oconee is currently in compliance and station documentation will be enhanced for further clarification. Areas for Improvement may not be submitted in the LAR.

The comparison utilizes NEI 04-02 "Guidance for Implementing A Risk-Informed, Performance-Based Fire Protection Program Under 10 CFR 50.48(c)," Revision 1 as a tool to determine the method and extent to which compliance is demonstrated. The Compliance Table, showing cross-reference and compliance statements, was based on Table B-1 of NEI 04-02. IV. REFERENCES

STATEMENTS OF NFPA 805 COMPLIANCE Each Section of Chapter 3 of NFPA 805 is individually addressed below: Section 3.1 General This chaptercontains the fundamental elements of the fire protectionprogram and specifies the minimum design requirements for fire protection systems and features. These fire protectionprogram elements and minimum design requirements shall not be subject to the performance-based methods permitted elsewhere in this standard. Previously approved alternativesfrom the fundamentalprotectionprogramattributesof this chapterby the AHJ take precedence over the requirements containedherein. Oconee Nuclear Station (ONS) compliance with the fire protection program elements and minimum design requirements presented in NFPA 805 Chapter 3 is not based on the performance-based methods permitted elsewhere in the standard.

Section 3.2 Fire Protection Plan 3.21 Intent A site-wide fire protection plan shall be established.This plan shall document management policy and program direction and shall define the responsibilities of those individuals responsiblefor the plan'simplementation. This section establishesthe criteriafor an integrated combination of components, procedures, and personnel to implement all fire protection programactivities. The Design Bases Specification for Fire Protection, OSS-0254.00-00-4008, documents the ONS Fire Protection Program including management policy, program direction and defines the organization, responsibilities and requirements of involved personnel. Many of these attributes have been updated and revised since original correspondence with the NRC including the January 16, 1978 letter from Duke to the NRC in response to the Nuclear Plant Fire Protection Functional Responsibilities, Administrative Controls and QualityAssurance (FRAQUA) letter and the original and updated Response to Appendix A to Branch Technical Position APCSB 9.5-1. The ONS fire protection program is currently based on, and complies with, the requirements of 1 OCFR50.48(a). Note that Oconee uses the terminology Fire Plan to represent the fire pre-plan (fire-fighting strategies) for fire scenarios at the site and uses the term Fire Protection Program (per 10CFR50.48) to delineate the implementation of fire protection policies at the plant.

Deviations from NFPA 72D are identified and justified by paragraph number per National Fire Code, 1975 as documented in the UFSAR, BTP comparison and Design Specification for Fire Protection. These Deviations from NFPA 72D are as follows: o 1221, 1223 - At Oconee, the alarm comes into the control room. The operator then notifies plant personnel of the fire location. o 1231 - Alarms on the control board are tested on each 12-hour shift by operator procedures. o 1232 - Procedures require annual testing of transmitters and water flow actuated devices. Water spray (deluge) systems for safety-related equipment are tested on an annual basis. o 2110 - The Oconee fire detection system is cabled using steel/aluminum sheathed #16 AWG cable for signal transmission. This cable meets or exceeds the requirements for physical and electrical protection as defined inNCA i i Ty o 2222, 2223 - The fire detection system at Oconee is powered from a battery backed power supply through a static inverter to provide 240/120 VAC.

On loss of normal station power, the system is designed to provide power to the fire detection system for one hour. In addition, a transfer switch is provided for transferring the inverter loads to regulated normal station AC power should a maffunction of the battery inverter supply occur. o 2521 - The annunciator audible alert at Oconee serves the fire detection system as well as other plant systems. The visual indicator provided by the visual display prevents operator confusion regarding source of the alarm. The fire detection system provides an audible and visual alarm and annunciation in the control room. Local audible alarms do not sound at the location of the fire. The operator receives the alarm in the control room, dispatches plant personnel to the location of the alarm to ascertain the local conditions and then, if necessary, summons the fire brigade via the Public Address System (PA) and a radio paging system.

Sectionalizing valves areprovided to allow isolationof varioussections of the system for maintenance;however there arelocations in the turbine building where a single piping break could affect both automatic water suppressionsystems and manual hose stations. The licensee has proposedto cross-connect the ends of the two auxiliarybuildingheadersto provide dual feed for the hose stationsin this area.

        'We conclude that, upon implementation of the modifications describedabove, the fire water piping system meets the objectives outlined in Section 2.2 of this report and are, therefore, acceptable." Note that modifications referred to in the conclusion pertain to cross-connections of the auxiliary building headers to provide dual feed for hose stations in the area and are not applicable to this NFPA 805 section.

Exception: Where a performance-based analysis determines the adequacy of building separation,the requirements of 3.11. 1 shall not apply. There are three main buildings in the power block; the Turbine Building, the Auxiliary Building and the Reactor Building. The Turbine Building and Auxiliary Building are separated by a three-hour rated fire barrier. The fire barrier is not a fully committed BTP 9.5-1 barrier and thus not maintained as such. Committed three hour fire barriers are controlled by SLC 16.9.5 and shown on the 0-310-K and 0-31 0-L series drawings include: 0 Unit 1 & 2 Equipment Rooms from 5'-4" north of column line 68 to 6'-4" south of column line 78.
