RECORD OF REVISION Issue Date Initial September 1977 Amendment 1 February 1978 Amendment 2 July 1978 Amendment 3 October 1978 Amendment 4 January 1979
4.2 Proposed t!odification Summary t!odifications to the design of the Farley Nuclear Plant have been proposed based on the results of the fire protect ion reevaluation described in this report. Table 4.2-1 is a summary of the principal modifications. Table 4.2-2 l3 is the schedule for i nplementation of these modifications. These modifi- is cations are described in detail in Section 4.3.5. The criteria used to establish the mod _fication requirements are the same for both Unit 1 and Unit 2. Due to differences between units, particularly in the area of cable routing, the detailed modifications for Unit 2 may be 2 different from Unit 1. Where sprinkler systems or area detection systems are noted in Table 4.2-1, the individual fire area hazards analysis should be consulted for the specific sprinkler or detector system locations within the fire area. The sprinkler systems do not necessarily cover the entire fire area. Amendment 3 10/78 4-21 Amendment 2 7/78

Amendment 2 7/78 Figure 4.3-33 Location of Fire Protection Equipment - Unit 2. Auxiliary Building - Plan at El 155'-0" 4-95/96
4.3.5 Fire Area Hazard Analysis This section provides an area-by-area analysis of the fire hazards and potential consequences for fire areas of the Farley Nuclear Plant. For each area or zone, the major equipment contained and its safety function are given. Installed and proposed fire protection features are provided and design features relating to fire safety of the area are provided. An inventory of combustible and flarnmable material is also given. The possible consequence of the fire in each area is indicated, and.the results of a fire are discussed. Evaluation sheets follow for each fire area or zone. Refer to Figures 4.3-3 through 4.3-41 for plant location. 4.3.5.1 Proposed Modifications (Electrical) This section describes the criteria used and the modifications I proposed for the protection of safe shutdown related electrical cable from the effects of an exposure fire. The criteria used in the evaluation for protection of electrical cables from an exposure fire are:
- 1. Automatic sprinklers will be installed in areas con-taining electrical cable or equipment of both safe 3 shutdown trains where both trains are subject to a single exposure fire. Both trains are considered subject to a single exposure fire when they are separated by less than 20 feet of clear space. 2
- 2. In addition to 1 above, a double-thick barrier consisting of two layers of 30-minute-rated enclosure 3 will be installed around one train of electrical cable where the train-to-train separation is less than 20 feet. (Conduit is not considered as an enclosure and is treated as a cable tray.)
- 3. Where interferences or the presence of power cable prohibit use of the double barrier, a half-hour barrier will be installed around both trains of cable. When wrapping of power cables may cause acceleration of aging resulting from excessive heat buildup, other measures will be proposed.
- 4. Areas containing motor control centers or high voltage switchgear and the control room are excluded from the sprinkler requirements of item 1. (This exclusion applies in the vicinity of the switchgear or MCC only and does not exclude entire rooms.
- 5. The following are special-case exceptions to these rules:
Amendment 4 1/79 Amendment 3 10/78 Amendment 2 7/70 4-137
- a. Fire area 4, Room 163 and valve gallery to Room 153.
Train A cabte tray in the valve gallery is approxi-mately 12 feet from the train a tray stack in Room 163. No barrier in proposed. A sprinkler is proposed. Justification: The partial-height shield wall between the spaces assures that common exposure to to a single fire is not possible. No intermediate exposed combustible material is located between the trayr..
- b. Fire area 4, Room 160. Two train B trays are locat-ed approximately 17 feet from the nearest Train A cable. Sprinklers are proposed for the area. Wrap-ping the Train B control cable tray with a half-hour g
barrier (Tray BIIF-24 ) and the bottom and sides only 3 of the power cable trays (BDE-9 and 15) is proposed. Justification: The open-top barrier for the power cable assures that the cable will not overheat. It is approximately 12 feet above the floor and 5 feet below the ceiling. Thus the power tray is isolated from an exposure fire.
- c. Fire Area 72A, El. 167'0" room. Two trains of safe-shutdown-related cable approach within 8 feet of each other in the northeast corner of the room, approximately 25 feet above the floor. No sprinkler or barrier is proposed.
Justification: The height of the cables above the piping header room floor assures adequate isolation from an exposure fire,
- d. Fire Area 40, Room 318, Cable Spreading room. A sprinkler system will be added to this area, however, no fire barriers will be installed. 4 Jus ti fication: Upon completion of the proposed mod-ifications to the hot shutdown panel, Lho plant can be brought to cold shutdown with the cable spreading room destroyed.
O Amendment 4 1/79 Amendment 3 10/78 4-138
FIRE PROTECTION A detection system is proposed for this area. The detection system covers the entire area with the exception of rooms 114, 123, 126, 127, and 130 which are duct cad pipe choses and contain no flam- , mabi e ma terial . Two manual hose stations located in Rooms 103 and 110, three dry chemical portable extinguishers located outside Rooms 105 and 106 and in Room 107, and one CO2 portable extinguisher located in Room 110 are provided. A forwater hose use in thislocated area. inAn Room 209 (Area 1-4) and a C09 hose reel located in Room 161 (Area 1-4) are available automatic sprinkler system'is proposes for Room 223. Appropriate barriers are pro- 3 posed for electrical cable as required by Section 4.3.5.1. CONSEQUENCES OF A FIRE
, Hot shutdown equipment located in this area consists of electrical cable of a single train in Room 223.
L 3; A fire originating in this area will be contained within the area because of the low quantity of combustibles, the barriers, and the automatic water suppression system in the area of tendon access openings in Room 223. In addition, the proposed detection system for this area will provide early warning of a fire, allowing the fire brigade adequate time to extinguish the fire. Should the fire brigade need to remove smoke to extinguish a fire in this area, smoke removal equipment will be available. Should the fire brigade ese water to extinguish the fire, the water will be either pumped or drained to ggg the waste holdup tank or the floor drain tank. (k.k, Although thet e is hot shutdown equipment in this area, hot shutdown capability is maintained in the event ~@@ of a fire siace only one train of electrical cable would be affected by a fire.

tihe e both trains of safe shutdown cables could be affected bv a single exposure fire, the automatic water l3 suppression will quickly extinguish the fire. Should the automatic water suppression system not function, the currently installed or proposed detection systems provide early warning, allowing the fire brigade to ex-tir.guish the fire using either installed or proposed hose-station or portable extinguishers. Should the fire brigade use water to extinguish the fire, the water will be handled by the drain syatem. Should the fire brigade need to remove smoke to extinguish the fire, portable smoke removal equipment will be available. Although there is safe shutdown equiptent and cable in this area, safe shutdown capability is maintained based 2l3 on the following:
- 1. Only one train of electrical cable would be affected, and z~
- 2. A fire originating in this area vill be quickly detected and extinguished.

A CO2 hose reel and a water hose cabinet located in Room 339 (Area 1-42) are available for use in this area. The proposed additional hose in Room 339 (Area 1-42) will also be available for use in this area. 2 Appropriate barriers are proposed for electrical cable as required by section 4.3.5.1. , ,3 CONSEOUENCE OF FIRE Safc shutdown equiptent located in this area consists of load centers, switchgear and electrical cable of two y 3 trains. This area is isolated from other areas by reinforced concrete walls and UL Class A doors. A fire originating in this area will be contained because of the quantity of cotbustible material and the barriers. In addition, a fire originating in the load centers or switchgear will be quickly suppressed by total flooding CO2 syste=s. Also, the detection systemin the area will provide early warning of a fire, allowing adequate time for the fire brigade to extinguish the fire utilizing the water hose or CO2 hose reel located in Room 339 (Area 1-42). Should the fire brigade need to remove smoke in order to extinguish a fire, portable smoke removal equip-p ment will be available. U m Should water be used to extinguish a fire, water will be drained to the hallway and then to the floor drain tank. Although there is safe shutdown equip =ent located in this area, safe shutdown capability is maintained in the 23 event of a fire based on the following:
- 1. only one train of electrical cable will be affected,
- 2. should a switchgear or load center be damaged by a fire, the redundant piece of equipment will be available, and
[y 3. a fire will be contained until extinguished. SS
