i SAFETY EVALUATION FOR PROPOSED TECHNICAL SPECIFICATION CHANIIES TO REFLECT A FIRE PROTfCTION MODIFICATION (JPTS-91-01Q) 1.

RESCRIPTION_OF THE PROPOSED CHANGEJ i

This application for an amendment to the James A. FitzPatrick Technical Specifications adds operability and surveillance requirements to Tables 3.12.1 and 4.12.1 to reflect a plant modification that willimprove fire protection at the i

Authority's FitzPatrick nuclear power plant. The modification installs an autornatic fire suppression system n the battery room corridor. The changes to the Technical Specifications are addressed below.

Minor ctuinges in format. such as type font, margins or hyphenation, are not described in this submittal. The a changes are typographical in nature and do not affect the content of the Technical Specifications.

PURPOSE OF THE P,ROPOSEDJHANGES The purpose of the proposed changes to the Technical Specifications is to add operability and surveillance requirements to Tables 3.12.1 and 4.12.1 to reflect a plant modification that willimprove fire protection at the Authority's FitzPatrick nuclear power plant.

On August 2,1991 Authonty personnel met with the NRC staff to discuss James A.

FitzPatrick Nuclear Power Plant fire protection. At this meeting the Authoritv committed to install a fire suppression system in the Battery Room Corridor prior to l

restart from the 1992 refueling outage. The Authority subsequently confirmed this commitment in Reference 1.

l

' 1 to JPN 92 057 SAFETY EVALUAT:ON Page 2 of G The NRC staff granted the Authority an exemption from the requirements of 10 CFR 50, Appendix R, Section Ill.G.3.b which allowed continued plant cperation until a fixed fFe suppression system is installed in this area (Reference 2). When this suppression system is ;nstalled, the battery room corridor (Fire Zone BR-5) will be in compliance with the requirements of 10 CFR 50, Appendix R, Section lil.G.3 and the exemption will no longer be requiied.

A description of fire Zone BR 5 was included in the attachment to Reference 3. As an interim compensatory measure a continuous fire watch has been posted in this area.

The modification will not change the existing fire detection capability in the battery room corridor which consists of ionization smoke detectors. These detectors will continue to alarm in the control room. in addition, a system pressure switch, installed with the new cuppression system, will indicate actuation by alarming in the contr01 room.

The new suppression system is a wet pipe design with fusible link sprinklers that are heat actuated to allow for sectionalized fire suppression capability. The system is automatically initiated when the nearby temperature reaches the melting point of the fusible Ill.

SAEETY IMPLlCATIONS OF THE PROPOS.f_Q CHANGES The proposed changes to the Technical Specifications have no adverse safety implications. The addition of a new suppresr. ion system for the Battery Room Corridor improvas the ability of the plant fire protection system to supprer.s fires.

The system was designed and analyzed in accordance with James A. FitzPatrick Fire Protection Program requirements (Reference 4). The operability and sur>eillance requirements added to reflect this modification are consistent with operability and surveillance requirements for similar fire protection systems. These requirements are also consistent with industry practice as contained in the Standard Technical Specifications (Reference 5). The changes do not alter the conclusions of the Fit 2 Patrick accident analyses as documented in the FSAR or tha NRC staff's SER.

Design and Analysis The modified fire suppression system was designed, analyzed, and installed in accordance with the FitzPatrick Fire Protection Program requirements. Specific design and analysis information related to the conclusions in the modification safety evaluation include the following:

1. Seismic interactions between the new fire suppression system and safety related equipment are prevented. The new fire suppression system is a Class M System that will be Seismic Class 11 supported. Supports are spaced to prevent the creation of missiles and to preclude pipe rupture (except for line cracks associated g

l' with moderate energy piping) with attendant flooding (Reference 6).

2. Adequato drainage is provided by fivo floor drains in thu battery room area (i.e.,

the battery room corridor and the two adjoining battery rooms) to accommodate fo;l system actuation. System operation, full flow through all sprinklers, exceeds the flooding associated with a moderate energy oipe crack (Reference 7). Water on the battery area floor will not damago safaty related equiprnent. The operation of tho batturieu is not af fected since the batteries are raised o the floor.

3. Water damage due to events such as inadvertent actuation or pipe crack from the fire suppression system will not affect the ability of the plant in achieving and maintaining safe shutdown from the control rooin. Because the affects of the postulated fire in the Battery Room Corridor (i.e., loss of shutdown capability from the control room) are more savoro than those from water damage, the addition of sprinklers provides a not safety benefit slnce the response time to such a fire is reduced with a corresponding reduction in potential fire damage.

Water spray in the battery room corridor will not af fect the cables located in the battery room corridor since all such cables are fully insulated and are impervious to the water spray. Operation of the circuits associated with those cables will remain unaffocted by the operation of the fire suppression system, including those cables required for RCIC operation. Establishing and inaintaining the reactor in a cold shutdown condition can, therefore, be achieved without resorting to remoto/ alternate shutdown (i.e., t. ig ADS /LPC0 from outside of the control rooma Watar damage to the distribution transformers (71PT-71ESSB1 and 71PT-71 ACB2) in the battery room corridor may cause the loss of "B" t* i control room indication. This will not prevent the operators from determining plant statua and achieving reactor shutdowr from the control room since the "A" train instruments remain available. Water damage to the equipment panels (71ESSB1 and 71 ACB2) resulting in the loss of vontilation for the battery rooms and battery room corridor will be mitigated by establishing temporary ventilation as required by Abnormal Operating Procedure AOP-58 (Roference 8).

Limiting Conditions for Operation The systern added to Table 3.12.1 is subject to the same limiting conditions for operation as those which are in Specification 3.12,B. This consistency with established operating restrictions and reporting requirements ensures that the plant modification will provide an equivalent level of protection and margin of safety as that provided by other fire protection systems.

Surveillance Hequirements An entry of "NONE" is proposed for the cyc!ing of valves in the new system. The now cuppression system is automatica'..y actuated by local heat levels requiring no detactor/ actuation circuitry and has only onb normally open testable valve. This valvo is an outside stem and yoke (OS&Y) valve which is manually operated for maintenance purposes an.1 system shutoff sihile the survoillance requirement is intended to allow operator determination of system operability. A surveillanc6

Attachtnent il to JpN-92-057 SAFETY EVALUATION Page 4 of 6 frequency of "NONE" is consistent with existing Technical Specification requitunents and current NRC requirements for wet pipe fire protection systems provided in Section 4.7.7.2 of tne Standard Technical Specifications.

Tho surveillance requirements to perform a spra" nozzle inspection and a nozzle air flow test are specified as " Nut Appbcable" in trus proposed Technical Specification amendment. IJFPA 15 (Ref erence 91 specifies that "All spray nozzles shall be inspected f or proper positioning, extemal loading, and corrosion, and cleaned if necessary at intervals of not more than twelve months

." The new suppression systun is a wet pipe system with closed sprinklers. The surveillance requirement of

'Not Applicable" is consistent with existing Technical Specification requireme:'ts and current NRC requirements for wet pipe fire protection systems provided in Section 4.7.7.2 of the Standard Technical Specifications.

A survei' lance requirement to inspect ihe f.eader integrity once per 1.5 vears is proposed for the battery toom corridor system. This is consistent with surveillance requirements for other similar fire protection systems in the Technical Specifications.

The frequency interva' is longer than NFPA 15 which requires annual inspection but is consistent with NRC Ouidance provided by Section 3/4.7.7.1 of the Standard Technical Specifications.

IV.

EV A U) AILQ_N_Q F_SlG ME!C A NT H A Z A R D S C O N SI D E R AT I Q N Operation of the FitzPatrick plant in accordance with the proposed Amendment would not involve a significant hazards consideration as defined in 10 CFR 50.92, since it would not:

1. mvolva a significant increase in the probability or consequences of an accident graviously evaluated.

The prooosed changes revise the Technica! Specifications to reflect a plant modification to the F;te Protection System. These changas willincrease the abihty to suppress fires. The modification to the fire protection system will not adversely affect the ability of plant personnel and fire protection equipment to detect and extinguish a fire. The proposed revis.on to Tables 3.12.1 and 4.12.1 of the Te^hnical Specifications will provide hmitin0 conditions of operation and surveillance requirements for the modification consistent with the limiting conditions of operation and surveillance requirements of other similar fire protection systems. These changes to the Technical Specifications assure that the new system is operable by periodic surveillance and that required e.ctions are taken if it is not available.

2. create the possibility e' a new or dif ferent kind of accident from any accident previously evaluated.

The modification does not create the possibility.f a new or dif ferent kind of accident. The modification to the fire protectico system provides additional protection against the possibihty of fire in the battery room corridor. The

' 1 to JPN 92-05!

SAFETY EVALUATION Page 5 of G proposed changes to the Technical Specifications uv not alter plant operations or operating procedures. The provision of a wet pipe sprinkler system can result in water sprays but the shutdown requirements due to previously analyzed fire effects bound the effects of water spray. The effects of inadvertent actuation have been evaluated and do not initiate a dif forent kind of accident. Althou0h it may cause the foss of certain equipment, it is less limiting than other analyzed events including a fire in this area.

? involve a significant reduction in a margin of safety.

The proposed revision to the Technical Specificadons to reflect the installation of a fire suppression system in the battery room corridor will not adversely af fect the marg' l dafety for equipment and personnel in thet area. These changes improve the plant's capability to suppress fires and limit fire dama00. The potential for flor n.g or water damage has been evaluated and is bounded by fire ef fects. This chan0e, therefore, results in a net improvement in plant safety.

V.

[N EIEMENTATION Of TH':_EROPQSED_Cif ANG ES These proposed changes wili not affect the ALARA Pro 0 ram at the FitzPatrick plant, nor will they impact no environment. The surveillance requirements will not add inspections to hi h radiation areas. The construction work to implement the 0

modification will be insido existin0 structures so there will be no environmental discharges. The construction work w ll not be in ;adiation areas. When completed, testin0 of the modification will be in compliance with current practices and will not impact the environment in a manner different than cutrent practice. These practices do not have unacceptable consequences. The modification supported by these technical specification changes willimprove the plant's Fire Protection Program capability in miti atin0 fires.

0 VI. QQNQWS10h The changes, as propot,ed, do not constitute an unreviewed safety question as defined in 10 CFR 50.59. That is, they:

1, will not chan0c the probability nor the consequences of an accident or malfunction of equipment important to safety as previously evaluated in the Safety Analysis Report;

2. will not increase the possibility of an accident o malfunc: an of a type different from any previously evaluated in the Safety Analysis Report;
3. will not reduce the margin of safety as defined in the basis for any technical specification; and i
4. involve no significant hazards consideration, as defined in 10 CFR 50.92.
