0 original Issue 1.0 OBJECTIVE The purpose of this Engineering Analysis is to show the impact of a fire on the West wall of the Turb Lube Oil Room adjacent to the tunnel travelling between the Turbine Building (EL. 590'-0") and the Feedwater Purity Building. Specifically, the analysis will consider the equivalent fire resistance of the barriers, combustible loading within the rooms and suppression and detection. Through these considerations, this analysis will demonstrate the ability of the system as a whole to prevent a direct fire exposure hazard to safety related equipment or openings in other fire area barriers required to guidelines 9602090071 960202 PDR ADOCK 05000255 G

4.0 ANALYSIS 4.1 General Reference 2 6. Page 27 General Guidelines for Plant Protection are discussed in the List of Changes and Response to Appendix A to BTP APCSB 9.5-1 and '

Regulatory Guide 1.78 and 1.101, Subsection D.I.j. The regulatory position states that concerning compartmentation ".. Floors, walls and ceilings enclosing separate fire areas should have minimum fire rating of three hours." It then goes on to state that "..The fire hazard in each area should be evaluated to determine barrier requirements." Also,. "Ifbarrier fire resistance cannot be made adequate, fire detection and suppression should be provided.. "

Based upon the abov-statements, it is apparent that the analysis of a specific barrier for acceptability should subsequently follow this order ofimportance:

The capability of the barrier must satisfy the minimum fire rating a.

guideline of 3-hours. If not then;

b. The barrier must be adequate to withstand the actual combustible loading in the fire areas separated by the barrier. If not then;

c. The actual configuration must be reviewed in order to take credit for other systems or circumstances that may increase the acceptability of the barrier (e.g. suppression, detection, etc...).

This analysis is based upon the above three criteria. It shall be used to demonstrate the capability of the fire barrier and its supporting systems to adequately prevent the spread of fire through the pipe tunnel separating the Feedwater Purity Building and the Turbine Building (EL. 590'-0").

Reference 2.9 Additional regulatory guidance is provided in NUREG 0800, Section 9.5.1, sub-section C.7.h, " Turbine Building," which states, in part:

The turbine building should be separated from adjacent structures containing safety-related equipment by a fire barrier with a mmimum rating of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />... Openings and penetrations in the fire barrier should be minimized and should not be located where the turbine lube oil or generator hydrogen cooling system creates a direct fire exposure hazard to the barrier. Considering the severity of the fire hazards, defense in depth may dictate additional protection to ensure barrier integrity.

In summary, the regulatory goal of the Turbine Lube Oil Room walls is to prevent a direct exposure fire hazard to either safety related equipment or openings and penetrations in fire barriers containing safety related equipment.

4.2 Description of the Fire Barrier The West wall of the Turbine Lube Oil Room is cormgated sheet metal directly connected to building support steel. The remaining walls are concrete block walls. The ceiling is approximately 8" thick reinforced concrete, based on field measurement, and the floor is reinforced concrete resting on the grade elevation. The two doors in the south wall are three-hour rated doors. There are two openings in the ceiling for equipment access. These openings are protected by concrete plugs the same thickness as the ceiling with metal framing. The room is curbed to contain potential oil spills or a single tank rupture within the room.

The Turbine Lube Oil Room is a free standing room within the main Turbine Building. Figure #1 shows a plan view of the area. This room does not provide structural support for the Turbine Building. However, the lower portion of two columns supporting the Turbine Building are located within the Turbine Lube Oil Room walls near the west end. Also, the concrete slab ceiling of the room is supported by structural steel beams. Neither the Turbine Building structural steel nor the ceiling beams are protected with fireproofmg materials. The size of the columns and beams and connecting steel outside the room, provide a large heat sink, and in conjunction with the automatic sprinkler system ensure these components will not fait prior to the arrival of additional fire fighting equipment to further suppress a fire in this area. The Palisades Fire Brigade is specifically trained to fight liquid petroleum fires as part of their hands on training.

This provides a direct air flow path from the Turbine Lebe Oil Room to just below the cedmg area of the Feedwater Purity Building. In addition, various piping penetrations are made in the west wall that are not sealed around the annular spaces. The upper 5 to 6 ft of the Turbine Lube Oil west wall is above the Feedwater Furity Tunnel ceiling and is exposed to the outside plant area.

l$II Side View 590' Elev. Front View Facing East Facing North The Feedwater Purity Tunnel connects the separate Feedwater Purity Reference 2.1 Building to the Turbine Building and is over 150 ft. long. A portion of this tunnel runs adjacent to the lower portion of the Turbine Lube Oil Room west wall. The tunnel is constructed of structural steel with a corrugated sheet metal wall and ceiling containing fiberglass insulation between the inner and outer sheet metal walls. The structure has no listed fire resistance rating.

The Turbine Building wall adjacent to the Feedwater Purity Tunnel is sheet metal supported on structural steel, similar to the Turbine Lube Oil west wall.

There are numerous openings in the east wall of the Feedwater Purity Tunnel adjr. cent to the Turbine Building and the south end of the tunnel opens directly into the Turbine Building.

2 4.3 Description of Combustible Loading Feedwater Purity Pioe Tunnel a.

The pipe tunnel contains two condensate pipes, a fuel oil transfer pipe (welded fittings), four lightly loaded cable trays, and other minor electrical and mechanical items. The electrical cables in the i

cable trays enter conduits approximately 20 ft from the south end of the tunnel opening into the 590' elevation of the Turbine Building. There are no significant combustible materials that traverse the openings from the Feedwater Purity Tunnelinto the Turbine Building. The Feedwater Purity Tunnel contains no safety Rererence 2.1I related equipment or circuits and has minimal combustible loading, so it ts not classified as a separate fire area.

b. Turbine Buildina (General Area tal EL 590'-0") North & West Sid.g Combustible loading in the Turbine Building general area at EL.

"*f*"nce 2 A 590'-0" is less than 20 minutes. This fire loading is spread over three elevations of the Turbine Building.

Reference 21 Equipment such as a heater drain cooler, feedwater heater, and air ejector are located near the east and south openings to the pipe tunnel. Any cable in this area is enclosed in conduit. Based on plant walkdowns, there are no significant combustibles within a radius of 20 ft from the various openings of the Feedwater Purity Tunnel into the 590' elevation of the Turbine Building. Waste oil tanks (T-130 and M-18) are located to the west of the Feedwater Purity Tunnel south opening. These tanks are positioned just outside of the 20 ft distance from the Feedwater Purity Tunnel, and are protected by a wet pipe sprinkler system.

The next level above the 590'-0" elevation, in this area of the Turbine Building, is the 607'-6" elevation. This floor levelis metal grating, which is not a confining space for smoke or heat. Therefore, any smoke or heat generated from combustibles on the 590' elevation would rise, not affecting the pipe tunnel, its contents, or the Feedwater Purity Building. This area is also connected to the turbine operating floor above by open stairwells and various large openings with metal open grating coverings that provide an even larger vent area for any smoke and hot gasses and minimize heat buildup on the 590' elevation.

Transient combustibles are administratively controlled in all plant areas by plant procedure. Transients brought into this area of the Turbine Building for maintenance and operating activities, would be expected to be minimal based upon the type of equipment located in the area.

c. Turbine Lube Oil Room The fire loading in the Turbine Lube Oil Room (nire Area 22),

Reference 2 3 results in an Equivalent Fire Severity of" greater than 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br />" and therefore has a VERY HIGH Fire Loading Classification. A significant fire in this area would be ventilation limited and couM not achieve the temperatures normally projected for an open combustible liquid pool fire.

The only significant openings to allow combustion air into the room are through the west wall to the Feedwater Purity Tunnel. These openings are estimated to provide less than 32 square feet of vent area as shown in Attachment 'A'. A parametric evaluation, using Reference 2.10 FPETOOL, of the average upper level smoke temperature for the Turbine Lube Oil Room using the 32 square feet vent opening is presented in Attachment 'B'. The results show that the fire would be ventilation limited in 2 to 8 minutes (120 to 500 seconds),

depending on the fire growth rate, with an upper level temperature of 800 F after 20 minutes.

The 800 F temperature is below the allowable structural steel average temperature limits for steel columns and beams of 1000 F Reference 2 2. Page 6-76 and 1100 F, respectively. This fire modelindicates adequate time is available for manual fire fighting activities to begin and provide additional cooling water on the affected structural steel. Additional runs of the model using either a 50% larger vent area or a 50%

lower concrete heat sink still yielded results below the average allowable structural steel temperature for columns and beams after a 20 minute fire duration.

No credit is taken for the full area automatic suppression system in arriving at these temperature values. Realistically, the sprinklers would greatly limit the temperature rise during any postui.,ted fire.

d. Feedwater Purity Building Reference 2.1 The Feedwater Purity Building is over 150 ft. from the Turbine Lube Oil Room west wall and the Turbine Building. Some electrical cables in cable tray traverse the distance separating these buildings inside the Feedwater Purity Pipe Tunnel. The Boiler Room in the Feedwater Purity Building is protected by a sprinkler system. The Feedwater Purity Building and connecting tunnel do Reference 2 tI not contain safety related equipment. No combustible loading calculation was performed for this building due to the large separation from the Turbine Building or any safety related structures or components.

4.4 Description of Suppression and Detection a.

Sucoression The Turbine Lube Oil Room is equipped with full area automatic Reference 2.13 wet pipe suppression system. Sprinkler hydraulic analysis shows I

the spray density is greater than 0.5 gpm/3,000 sq. R. which exceeds the 0.30 gpm/3,000 sq. R. design specified for Extra Ref 2144 L24 Hazard (Group 1) protection.

Manual suppression is provided by a hose station located less than 20 R. away from the Turbine Building entrance to the pipe tunnel at the 590'-0" ekvation. Various other hose stations are located throughout the Turbine Building on this and other elevations to pre.ide backup fire fighting capability. Fire fighting foam equipment is located just outside the Turbine Lube Oil Room on the 590'-0" elevation.

The Turbine Building has partial area automatic wet pipe suppression systems located in areas around the Turbine Lube Oil Room. These systems provide protection for areas with cable trays, lube oil, hydraulic oil reservoirs and of6ce areas on both the 590'-0" elevation and the 607'-6" elevation. The Turbine Building areas to the north, south and east of the Turbine Lube Oil Room are protected by these sprinkler systems. Portions of these systems are located between the Turbine Lube Oil Room and the Component Cooling Water (CCW) Pump Room walllocated east of the Turbine Lube Oil Room. The CCW Pump Room wall, which contains non-fire rated openings, provides separation of safety related equipment from the Turbine Building.

b. Detection There is no automatic detection located in the general Turbine Building area near the access door to the pipe gallery (EL. 590'-0"). However, the automatic sprinkler systems in both the Turbine Lube Oil Room and the Turbine Building are equipped with flow alarms. These alarms will provide noti 6 cation to the continuously manned plant Control Room.

c. Fire Brigade /Eauioment The plant Sre brigade tra'ining program includes actualinvolvement with fighting flammable liquid fires during the live fire training. The 590'-0" elevation of the Turbine Building contains one of the fire brigade depot areas for equipment storage providing ready access to equipment for a Sre in this area. Equipment such as self-contained vent fans capable of delivering 16,000 CFM are also located outside the

..v.,

s Turbine Lube Oil Room. As mentioned above, the area also contains fire fighting foam equipment for a potential lube oil fire.

4.5 Overview of Fire Barrier Concerns The primary concern for this area is the spread of a fire from the Turbine Lube Oil Room into the Turbine Building that may ultimately affect either safety related equipment in the Turbine Building or openings in walls separating the Turbine Building from safety related plant areas such as the CCW Pump i

Room. There is minimal concern for the spread of fire from the Turbine Building bick into the Turbine Lube Oil Room due to the low combustible i

loading on the Turbine Building side.

From the descriptions provided above there are several defense-in-dupth barriers to prevent the spread of fire from the Turbine Lube Oil Room back into the Turbine Building. These can be summarized as fo!!ows:

e The Turbine Lube Oil Room has full area automatic suppression and the curbing is provided to contain potential oil spills within the room.

e The non-fire rated west wallis exposed to the exterior for the upper 5 to 6 ft. and if wall failure did occur due to a fire, then this area would be expected to fail first venting the smoke and hot gasses outside the Turbine Building area.

e The size of the worst case fire in the Turbine Lube Oil Room is not projected to reach temperatures that may fail the west wall for over 20 minutes. The ventilation limited fire would remain below 1000' F for that period of time allowing the plant fire brigade time to establish manual fire fighting apparatus to contain and extinguish the fire.

e Any smoke and hot gasses vented into the Feedwater Purity Tunnel and Turbine Building would ultimately disperse over the entire Turbine Building area and minimize heat stress on nearby equipment. The areas within 20 ft. of the Feedwater Purity Tunnel opemng on the 590' elevation into the Turbine Building are virtually devoid of combustible material and contain no safety related equipment.

e The plant fire brigade is available to respond to any plant fire and is specifically trained to fight oil fueled fires.

The remaining concern is for direct fire exposure to openings in walls separating safety related equipment from the Turbine Building. The west wall of the CCW Pump Room contains various openings into the Turbine Building and these are described in a separate evaluation. However, the additional

M PALISADES NUCLEAR PLA:sf RA. ppp_9s.og4 pggy ANALYSIS CONTINUATION SHEET Sheet 11 Rev s 0 man - e5 m defense-in-depth features, from those described above, that protect these openings are a follows:

e The areas within 20 ft. of these openings on the Turbine Building side are almost devoid of combustible materials. Floor drains are located throughout the Turbine Building to prevent the spread ofliquid pool fires to the area adjacent to these openings on the 590' elevation.

Automatic wet pipe suppression systems are located in the Turbine e

Building such that a fire on the west side of the Turbine Building (near the Turbine Lube Oil area) would have to cross these protected areas before exposure of the openings could occur.

Additionally, the original Appendix R post fire safe shutdown evaluation and the current revision to this analysis do not consider the Turbine Building and the Reference 2.ll Turbine Lube Oil Room as requiring separate fire areas, because no safe shutdown components are located in the Turbine Lube Oil Room. Should a fire spread from the Turbine Lube Oil Room to the Turbine Building, it would result in the same consequences as a Turbine Building fire alone. The Turbine Building and the CCW Pump Room are evaluated as separate fire areas in the Appendix R analysis. However, since the west wall of the Turbine Lube Oil Room is facing opposite and over 100' away from the unrated openings in the CCW Pump Room wall, no direct fire exposure hazard is considered credible.

5.0 CONCLUSION

The regulatory goal of the Turbine Lube Oil Room walls is to prevent a direct exposure fire hazard to either safety related equipment or openings and penetrations in fire barriers containing safety related equipment. The plant configuration described above provides adequate defense-in-depth such that the system as a whole prevents a direct fire exposure hazard to safety related equipment or openings in other fire area barriers required to meet NRC guidelines.

Page 3 of 4 Vent Area Calculation The upper portion of the sheet metal wall is located 7.5" horizontally away from the pipe tunnel ceiling I-beam and 7" below the lower flange of the I-beam. The air flow through this opening will be across the diagonal area calculated as follows:

Diagonal = (((7.5")2 + (7.)2) = ((56.25 + 49) = (105.25 = 10.26 or conservatively 10.5" The diagonal opening along the majority of the west wall progresses for 20'-4" (24' minus 3' 8").

The area of this portion of the opening is calculated as A below:

i A = (10.5"/12) R. X (20' + 4"/12) ft. = 0.875 ft. X 20.34 ft. = 17.80 R2 i

The semi-circular cutout for a pipe is conservatively assumed to be completely open without a pipe and the area is calculated as A below:

2 A = 1/2 X ((n(6/12)2)/4) = 1/2 X (3.14 X 0 25)/4) = 0.098 ft2 2

The rectangle cutout for a pipe is conservatively assumed to be completely open without a pipe and the area is calculated as A below:

3 A = (22"/12) ft. X (20"/12) ft. = 1.83 ft. X 1.67 R. = 3.06 ft2 3

The right most diagonal opening is located 7.5" horizontally away from the pipe tunnel I-beam and 22" below the lower flange of the I-beam. The air flow through this opening will be across the diagonal area calculated as follows:

2nd Diagonal = (((7.5")2 + (22")2) = ((56.25 + 484) = (540.25 = 23.25" The rectangle cutout for the remaining 3'-8" of the west wallis calculated as A. below:

A, = (23.25"/12) ft. X (3' + 8"/12) ft. = 1.94 ft. X 3.67 ft. = 7.12 fiz The area of the three pipe penetrations, which are essentially filled with the pipes, are conservatively assumed to be completely open and the area is calculated as A, below:

A, = ((n(6"/12)2)/4) + ((n(7"/12)2)/4) + ((n(5"/12)2)/4) = 0.196 + 0.267 + 0.136 =

2

= 0.60 ft The conservative total vent area is the sum of A through A, as follows:

t Total Area = 17.80 + 0.098 + 3.06 + 7.12 + 0.60 = 28.68 ft To further compensate for field measurement errors a 10% safety factor will be added to the Area to conservatively estimate the amount of air available to support combustion as follows:

2 Total Area = 28.68 X 1.10 = 31.55, the area to be used in FPETOOL will be 32 ft

EA-FPP-95-054 Page 4 of 4 Turbine Lube Oil Room Surface Area ofInterior Walls The FPETOOL calculation of average upper level temperature includes an evaluation of the heat sink provided by the surrounding enclosure materials. The Turbine Lube Oil Room is constructed of 8" concrete block on three sides, a reinforced concrete ceiling that is also 8" thick and a reinforced concrete floor that is greater than 8" thick. Conservatively, the 8" thickness will be used for all the enclosure concrete surfaces. The room is approximately 21 R. high, but due to obstructions to air flow caused by the steel beams supporting the ceiling a conservative value of 20 ft. is used for the wall height. The lower number will provide both a higher temperature for a given fire size and a lower heat sink value than is realistically available. Based on the floor are 24 R. by 80 ft. the interior wall surface area is calculated as follows:

Floor / Ceiling = 80' Long X 24' Wide X 2 surfaces = 3,840 R.2 N & S Walls = 80' Long X 20' High X 2 surfaces = 3,200 R.2 East Wall

= 20' High X 24' Long X 1 surface = 480 R.2 Total Surface Area = 7,520 ft.2 Conservatively, the structural steel is not included in the heat sink values used for calculating t upper level smoke temperature in the room.
