Calculation No.: OSC-9295 Revision No.: 1 Applicable Units: Oconee Unit 1, 2, & 3 Page 1 of 85 I. 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 1 OCFR50.48(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 N FPA 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 program and 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 alternatives from the fundamental protection program attributes of this chapter by the AHJ take precedence over the requirements contained herein.Oconee Nuclear Station (ONS) compliance with the fire protection program elements and.rnimum-_design-requirements-presented-in-N FP-A-805-Chapter3-is-noLbased-on-the.

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 protection plan shall be established.

This plan shall document management policy and program direction and shall define the responsibilities of those individuals responsible for the plan's implementation.

This section establishes the criteria for 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.Reference(s):

The fire water supply shall be capable of delivering this design demand with the hydraulically least demanding portion of fire main loop out of service.The greatest demand for fire protection water is based on 1,000 gpm for fire hose plus 2,571 Calculation No.: OSC-9295 Revision No.: 1 Applicable Units: Oconee Unit 1, 2, & 3 Page 50 of 85 gpm (all sprinklerheads opened and flowing in the Unit 3 Turbine Building Mezzanine Level Sprinkler System) plus 500 gpm non-fire related service water for a total of 4,071 gpm. 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 rated at 117psi net pressure.

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 and one 500 gpmjockeypump, all rated at 117 psi net pressure.

DOCUMENT C20-UP CHNEROIRED O itzSt hdA 6j/ Pit, KCIE Se 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 1 OCFR50 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-...................

.........Generating Plants (2001 Edition).

Oconee has elected to transition to 1OCFR50.48(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 -N FPA 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

The Fire Alarm and Detection Devices in general are installed in accordance with NFPA 72D (1975). The Design Basis Specification for the Fire Detection System, Design Basis Specification for Fire Protection, and BTP comparison provide additional detail on the Oconee fire detection system.The fire alarm systems are provided with capabilities to relay the fire-related signals from any Calculation No.: OSC-9295 Revision No.: 0 Applicable Units: Oconee Unit 1, 2, & 3 Page 65 of 84 fire detection device, actuation of fixed fire suppression systems, actuation of manual fire alarm stations, actuation of supervisory signals, and alarm of trouble conditions.

Start of the HPSW pumps used for the fire protection systems also alarm in the control room.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. These batteries which are Class 1E but utilized as Non-Class 1E are continuously charged from normal station power. 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.Radwaste Fire Detection system alarms to the Unit 3 Control Room and Radwaste Facility control room.The SSF Fire Detection system alarm to the Unit 1 &2 Control Room, Unit 3 Control Room and the SSF Control Room.Keowee Hydro Station Fire Detection system provides an audible and visual alarm and annunciation in Keowee and ONS Unit 2 Control Room.The NRC August 11, 1978 SER Section 4.2 states 'The plant has a protective signaling Calculation No.: OSC-9295 Revision No.: 0 Applicable Units: Oconee Unit 1, 2, & 3 Page 66 of 84 system which transmits alarms from fire detectors and water spray system actuation to the control room.

There is no distinct audible fire alarm signal provided in the control room.""Smoke detectors in some areas of the plant containing electrical cable insulation are located lower than the ceiling level and, therefore, may not respond as rapidly as they would if located at the ceiling. However, since fires in cable insulation generate heavy quantities of smoke, reasonably prompt detection can be expected.

Ionization type smoke detectors are used throughout the plant. In some tests, ionization type detectors have not responded as rapidly to 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 areas of the plant are detected, the licensee has proposed, in addition to the exiting detection system, to provide detectors in all areas containing safe 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 equipment such that the plant can 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 proposed modifications, the fire detection and signaling system in conjunction with the safe shutdown system satisfies the objectives of Section 2.2 of this report and is, therefore, acceptable."

Through penetration fire stops for penetrations such as pipes, conduits, cables, pneumatic tubes, etc in rated fire barriers are generally provided with rated penetration seals.The site FPE maintains the Penetration Seal Database in the site EDB and 86-10 Evaluation calculation documenting the acceptability of the station penetration seals in Calculation OSC-7350.OSC-7359 (DPC 1435.00-00-0006) identifies that Oconee is committed to the criteria of IEEE P634 for electrical and mechanical fire barrier penetration seals.UFSAR Section 9.5.1.4.3 Item 4 states "Electrical penetration seal designs shall be subjected to a standard exposure fire that follows the ASTM E- 119 Standard Time- Temperature Curve.The acceptance criteria from IEEE 634 (which is identical to that of IEEE P634/D4)_

shall be used to evaluate the acceptability of test assemblies.

The IEEE 634 acceptance limit for ONS unexposed side electrical penetration temperature shall be 700 0 F. This temperature was selected because the IEEE 634 acceptance criteria is the auto-ignition temperature of the outer cable covering and material in contact with the cable penetration fire stop, or 700 0 F, whichever is lower. The ignition temperature of outer cable jacketing has been determined to be 735 0 F.Mechanical penetration seal designs shall be subjected to a standard exposure fire that follows the ASTM E- 119 Standard Time-Temperature Curve. The acceptance criteria from IEEE-634 (which is identical to that of IEEE P634/D4) shall be used to evaluate the acceptability of test assemblies.

The IEEE 634 acceptance limit for Duke Power mechanical penetration seals shall be 680 0 F. This temperature was selected because it represents the lowest auto ignition temperature of any material normally found in close proximity to piping penetrations (Armstrong Armalok pipe insulation)." The use of unrated fire penetrations in the ceiling of the West Penetration Room and unrated mechanical pipe penetrations between the Reactor Building and Penetration Rooms were evaluated by the NRC and found to be acceptable in the August 21, 1989 evaluation that granted an Exemption from the Fire Protection Requirements of Section III.G of 10 CFR Part 50, Appendix R.The NRC also evaluated the separation between the East and West penetration rooms and determined that the electrical divisions were "effectively separated by a three-hour fire barrier."
