SUMMARY

OF CHANGES AMENDMENT 12 OF THE FIRE PROTECTION REPORT - ZION STATION The "affected pages" listed below are the pages revised in Amendment 13.

FPR Revision # 2011-03 Derate select Radiological Controlled Area (RCA) fires barriers. The fire barrier derating is justified by the elimination of significant combustible loads and the quantity of radioactive material remaining in the RCA. Additionally, combustible load information has been updated to reflect the removal of select combustible loads.

Affected pages: 2-5, 2-8, 2-10, 2-12, 2-15, 2-16, 2-20, 2-21, 2-25, 2-26, 2-27, 2-28, 2-29, 2-30, 2-31, 2-32, 2-33, 2-34, 2-40, 2-41, 2-42, 3-1, 3-1a, 3-9, 3-10, 3-16, 3-17, 3-67, 3-69, 3-113, 3-114, 3-116, 3-124, 3-125, 3-127, 3-131, 3-133, 3-135, 3-145, 3-146, 3-218, 3-239, 3-241, 3-251, 3-252, 3-261, 3-266, 3-267, 3-268, 3-269 Affected Figures: 2-1 thru 2-14, 2-17,2-22, 2-23 thru 2-45 FPR Revision # 2011-04 Revise the FPR to reflect the conversion of the FP system standpipes and hose stations inside containment from a wet to a dry system.

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT 2.5.2 Radioactive Contamination Radioactive contamination is present in many Zion Station fire areas, and could be spread by the smoke from a fire in a radiologically contaminated area. To ensure that the risk of spreading contamination is minimized, the plant continues to apply the defense-in-depth concept to those areas where radiological contamination exists. This effort includes:

a. Controlling ignition sources All hot work and transient ignition sources are strictly controlled and monitored by procedure.

b. Controlling the presence, placement and removal of combustibles during decommissioning The storage of transient combustibles in these plant areas is limited in amount, duration and in areas where it can be placed, and is also strictly controlled by procedure.

The removal and storage of combustibles from contaminated areas during decommissioning is controlled to ensure that a Radiological Hazard is not created.

c. Providing suppression for rapid extinguishing of fires Hose stations are available within the RCA; on each elevation of the AB, inside the Containments, and inside the FB.

d. Maintaining fire barriers Internal walls of the RCA that were credited as fire barriers prior to onset of decommissioning will be retained as unrated barriers until the area is dismantled. Fire barriers for areas that contain significant amounts of combustibles are being maintained. Fire barriers are shown on Figures 2-1 to 2-14.

e. Maintaining fire detection Fire detection is provided in the Auxiliary Building and Fuel Building where a fire could Induce a hazardous radiological release. Those fire detection systems that presently protect areas of the plant where a fire could Induce a hazardous radiological release are maintained as functional systems, subject to NFPA and Insurance Company required inspections, tests, and maintenance.

f. Maintaining Emergency Response Capability The Zion Emergency Response Capability utilizes both onsite and offsite fire responders during a fire emergency. The ZMFD and the incipient fire responder(s) are capable of rapid response to manually control any fires that do occur.

2-5

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT

g. Providing control of smoke releases Smoke is controlled during a radiological fire with barriers and ventilation. Fixed, backup, and portable ventilation flow paths minimize the release of smoke.

h. Radiation Protection Personnel Radiation Protection personnel are assigned duty to assist site fire responders during fires.

Radiation Protection personnel provide information, direction, and monitoring as needed to minimize contamination and dose to the firefighters.

i. Pre-Fire Plans The Pre-Fire Plans provide information to the site fire responders about the layout of the plant, routes available to the fire scene, and locations of fire suppression equipment.

By applying the defense-in-depth features described above, Zion Station meets this objective.

2.5.3 Minimizing Release of Radioactive Materials For all decommissioning activities, the amount of radioactivity and combustibles in the associated work areas will be evaluated to minimize the possibility that the consequences of a fire will result in a Radiological Hazard. The current fire loading and the amount of radioactivity for each fire area will be assessed prior to start of any decommissioning work. Combustibles and/or radioactivity will be reduced, when possible, and additional incipient fire responders will be provided as necessary to ensure that radioactive* releases are less than the limits of IOCFR20 in the event of a fire. Administrative controls will be established to control the removal and storage of contaminated combustibles.

2-6

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT 2.6 FIRE HAZARDS ANALYSIS AND ENGINEERING DESIGN 2.6.1 Fire Hazards Analysis The Fire Hazards Analysis (FHA) shall be revised to incorporate any: design changes to fire protection equipment, changes to the fire protection capability in fire zones containing structures, systems and components Important to the Defueled Condition, changes to the fire protection capability in fire zones within the RCA, or increases to fire loads where a fire could cause the release or spread of radioactive material. The revision shall:

" Consider potential insitu and transient fire hazards,

Determine the consequences of a fire in any location onsite which contains SSC's ITDC, or

" The potential for a fire-caused release or spread of radioactive material.

" Determine the fire induced radiological hazards of a fire in any location in the plant to ensure the risk of such fire Is minimized to the environment, plant personnel and the public.

Revisions to the FHA described above shall be supported by all necessary engineering evaluations, effectiveness reviews, calculations, and/or test results.

During the course of decommissioning, fixed fire loads (i.e., fire loads described in the FHA) will be removed from the designated fire zones. Administrative controls defined in the Transient Combustible Control program and incorporated into work packages will ensure that the process of decommissioning does not result in creating an unmonitored Radiological Hazard from the movement and collection of fire loads. As the intent and process of decommissioning ultimately results in the removal of fixed fire loads, the overall outcome is a reduction in the fire loading as described in the FHA. For the purpose of facilitating decommissioning, the Fire Hazards Analysis assumes that the movement and ultimate removal of fire loads described in the FHA will result in the fire loading to temporarily increase in adjacent fire zones and other fire zones enroute to removal of the fire loads. This assumption is included, in part, as an Administrative Transient Combustible Load. Administrative controls are established to control the amounts, the movement, and temporary storage of these combustibles (General considerations are described in Section 2.8).

Therefore, re-analysis of fire zones to account for a reduction in fixed fire loads is not required for decommissioning to proceed.

2.6.2 Fire Protection Features Desian Criteria Existing fire protection design features were developed using the guidance of the NFPA codes and standards and recognized industry standards in effect at the time of installation. However, justified deviations exist. All future fire protection design features shall be developed using the guidance of the NFPA codes and standards and/or recognized industry standards in effect at the time of installation.

2.6.3 Fire Protection Enaqineerina Evaluations Fire protection engineering evaluations shall be used to evaluate deviations from applicable code or regulatory requirements for new or existing fire protection systems associated with the equipment ITDC and for those areas where a fire could cause the release or spread of radioactive material. The fire protection engineering evaluation shall be performed by a person who is cognizant of the codes, standards, and regulatory requirements that govern the design. The fire protection engineering evaluation shall be reviewed or approved by a person who is qualified by ZionSolutions as a Fire Protection Engineer.

Zion Station can make changes to the Fire Protection Program without NRC approval if these changes do not reduce the effectiveness of fire protection for facilities, systems, and equipment which could result in a radiological hazard, taking into account site conditions and activities. Zion Station shall continue to use the 10CFR50.59 process and an effectiveness review to evaluate changes to the Fire Protection Program.

Amendment 13, July 2013 I ZION STATION FIRE PROTECTION REPORT 2.6.4 Fire Protection System Description Plant fire protection is provided by a loop fire header distribution system using fire hydrants, fire hose reels, fixed sprinkler or water spray systems, and water deluge systems. Portable fire extinguishers are provided throughout the plant and selected areas are provided with fixed carbon dioxide, dry chemical, or foam extinguishing systems. The automatic suppression systems are listed in Table 2.8.2. Systems and components required to be functional are controlled by the Administrative Technical Requirements (ATRs). All other systems are required in order to meet insurance requirements. Generally, the fire protection systems, to the extent possible, are designed in accordance with Nuclear Electric Insurance Limited (NEIL) guidelines and the applicable NFPA standards.

A 10-inch yard main loop (ring header) encircles the entire plant with fire hydrants spaced at approximately 250-foot intervals. Note that Hydrant #7 has been removed resulting in an approximate 500 foot interval between Hydrants #6 and #8. This yard main loop can be isolated into two segments with each one having an independent supply path source. The turbine building has a 10-inch loop header following the exterior walls of the turbine building. The auxiliary building is supplied by a 10-inch header which is fed from the yard main on both the Unit 1 and Unit 2 sides and from the turbine building header.

The turbine building is fed from the yard main loop and from the cross connection to the auxiliary building mentioned above. The reactor containments and the fuel handling building are fed from the auxiliary building 10-inch header and the crib house is fed directly from the fire pump discharge header. The main headers can be isolated so that water can be supplied to a portion of each building if a break occurs in a header. Hose stations are located throughout the buildings at approximately 100-foot intervals on each floor. Each hose station in the Aux building and Fuel building contains at least 50 feet of hose.

Most areas where oil or other significant amounts of combustible materials may be stored or handled are provided with a fixed fire protection system as described in the fire hazards analysis for each fire zone.

The FP water suppression system is a dual function system that allows SW to flow through the FP piping to supply plant cooling loads, while still providing the required FP flow. The FP water suppression system pressure is normally maintained from one of the SW pumps, with the Motor Driven (MD) Fire Pump in standby. The SW pump also provides flow to various components within the plant through FP piping. The SW pumps are located in the Crib House and are rated at 3000 gpm. The normal operating pressure of the SW pump, and hence the FP system, is-100 psig. In this dual function configuration, SW flow (normally) exists through the fire protection piping to various plant cooling loads. Isolation valves are installed to allow isolation of those components from the FP system. The site required flow demand, as described in NEIL Loss Control Standard 3.2.15.1.1, is the largest single automatic fixed water extinguishing system plus 500 gpm hose stream allowance; 750 gpm plus 500 gpm for a total flow of 1250 gpm. In the event of a fire, the MD Fire Pump has the capacity to supply the required FP demand load including the SW loads. The analysis is documented in Zion Calculation 22R-0-150M-0008.

Whenever the fire protection system header in the crib house falls to "86 psig, the motor-driven fire pump will automatically start and maintain the fire protection system headers at 125-psig to 140-psig pressure.

The fire pump is rated at 2000 gpm at 141 psig, and takes suction directly from the crib house forebay which is supplied by Lake Michigan. The site city water supply can be used to fight fires during a loss of offsite power event when the motor driven fire pump is unavailable. The Zion Fire Department has the capability to connect a pumper truck to an onsite municipal hydrant. The pumper truck discharge can be connected to an adjacent fire protection ring header hydrant and thus provide a water supply to the header.

2-8

Amendment 13. July 2013 ZION STATION FIRE PROTECTION REPORT In the event that the fire pump fails to operate, then water could be supplied to the fire protection system headers from the service water pumps.

The portion of the plant Fire Protection System that is required for the control of radiological fires is controlled by the Administrative Technical Requirements. The major components of that portion are specified in Table 2.6.1. The valves identified in Table 2.6.1 provide the fire suppression flowpaths to the areas that require control of radiological fires; the Auxiliary Building, the Fuel Building and the two Containment Buildings. There are three independent flowpaths to these areas from the underground ring header. Isolation valves are designated to provide isolation in the event of maintenance or leakage to allow continued fire suppression to these areas.

2.6.5 Detection System Description/Desin Features A general description of the placement of the Fire Detection System at Zion Station is shown on Table 2.8.2. Drawings of the fire water protection system are contained in station drawings M-43 and M-513.

Fire detection equipment required to be functional is listed in the ATR's. All other fire detection is present to satisfy insurance requirements.

Detection systems have been designed to provide coverage for one or more of the following situations:

1. General area detection;

2. Specific hazard detection;

3. Specific equipment detection (primary endangered by an exposure fire); and

4. Supplement protection of suppression systems for specific hazards (these detectors are in addition to the heat detectors provided to actuate certain suppression systems).

The Fire Alarm and Detection Systems, where provided, are designed and installed under the general guidance of National Fire Protection Association (NFPA) 72D and 72E. Certain code deviations exist, but these deviations have been evaluated. The number, type and location of detectors was determined generally in accordance with the recommendations of the manufacturers and the guidelines established in NFPA 72E. All fire alarms and fire detectors in radiological areas provide an audible and visual alarm in the Plant Control Room.

Amendment 13, July 2013 I ZION STATION FIRE PROTECTION REPORT 2.6.6 Electrical Design Features and Criteria The cable tray and conduit penetrations through fire barriers have been sealed and tested.

Cable penetrations entering the main control room from the cable spreading room below are sealed with cellular concrete and covered with Flammastic, Vimasco or an equivalent coating.

All cable Is qualified by flame tests at least as severe as those listed in IEEE-383 - 1974. The cables generally can be considered self-extinguishing and non-flame propagating.

Emergency lights are provided to aid in personnel egress from the plant in case of fire. A complete list of emergency lights can be found in the plant electrical maintenance procedures.

2.6.7 Mechanical Desian Features and Crteteda Insulation on piping was not considered in the heat load calculation because of its low "Btu* content, and the dispersed nature of this loading throughout the station.

The rupture of process piping as a result of fires was not considered. The assumption made was the continued flow would act as a heat sink and contribute to the maintenance of the integrity of the piping.

The grease contained in some motor-operated valves was not considered because of the limited number of these types of valves that contained a significant amount of lubricating grease and their spatial separation within the plant.

Pipe penetrations through fire barriers have been sealed. Fire barrier assemblies include the fire walls, fire doors, fire dampers, and penetration seals that make up a fire barrier.

No new fire barriers were installed to meet the requirements of I OCFR50.48(f) after the plant was permanently shutdown; credit was taken for the location of existing fire barriers in the plant. One of the original primary goals of passive fire barriers was the protection of redundant safe-shutdown trainsithis goal is no longer required. The remaining goal, which is preventing the spread and release of radioactive contamination during a fire which could result in a radiological hazard, is maintained by the existing barriers and ventilation boundaries. As shown by calculation (references i and j), based on the amount of contamination remaining and the type of combustibles present (i.e. mainly cable insulation), a fire that results in a radiological hazard is highly unlikely.

2-10

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT 2.6.8 Structural Design Features and Criteria Structural design elements and materials descriptions are as follows:

Concrete was used in the construction of walls, floor slabs, and roof slabs. Fire-resistant covering of steel beams and columns is of a mix which includes a proportion of carbonate-type aggregate. This factor was a consideration in determining the fire resistance of these structural elements.

Hollow concrete blocks used in the construction of walls conform to the applicable requirements of ASTM C-90 for Type I units and for Grade U-I block and are formed from a mix containing lightweight, expanded slag aggregate. Blocks were laid In a standard running-bond pattern with 318-inch-thick horizontal and vertical mortar joints. Heavy-duty steel ladder-type continuous reinforcing ties are provided in the horizontal joints at 16 inches on centers vertically.

Three layers of preformed joint filler, which were used to pack joints in masonry walls, were used throughout the plant; self-expanding cork-type, sponge rubber-type, and polyethylene foam-type. Rubber sealant used to seal the faces of joints in masonry walls which were packed with preformed joint filler is a Type A Thiokol base sealant.

The exterior roof covering, which is referred to as UL Class A roof covering, Is a four-ply built-up pitch, felt, and gravel roofing, System F, with 1-Inch-thick preformed board insulation. This roof covering complies in all respects with the applicable requirements of the Underwriters' Laboratories for Class A rating. This rating applies to roof coverings which are effective against severe fire exposure and under such exposures are not readily flammable and do not carry or communicate fire; afford a fairly high degree of fire protection to the roof deck; do not slip from position; possess no flying brand hazard; and do not require frequent repairs in order to maintain their fire-resistive properties.

Penetrations in a designated fire resistive barrier are protected so that they have an. appropriate fire resistance rating for the hazard present.

2.6.9 HVAC Deeicn Features and Cteria Fire dampers are generally installed in HVAC system ductwork where a duct passes through a designed fire barrier, or other technical justification has been provided.

In the fire hazards analysis portions of this report, the assumption is made that all fire dampers are 1-1/2-hour labeled unless otherwise noted. In areas where total flooding gaseous suppression systems are used, dampers in the ventilation system are automatically closed.

2-11

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT 2.6.10 Surveillance Testing/ Maintenance Fire protection test procedures shall be established that:

a. Demonstrate functionality and conformance with design and system readiness requirements,

b. Identify types, frequencies and detailed procedures for testing, C. Properly evaluate and act upon test results.

Test procedure requirements may vary depending upon the categorization of the equipment that the fire protection feature is protecting. The technical requirements for functional system FP test procedures are contained in the ATR's. The test procedures are located in the Zion 200 series periodic tests (PT's).

Preventive maintenance (PM) procedures shall be established for fire protection features. The PM program shall take the following into consideration: manufacturers recommendations, consensus code or insurance guidance, and results from tests and inspections. FP PM procedures are filed in the Zion Maintenance Department. Other PM procedures have been incorporated in Zion 200 series periodic tests where applicable and convenient.

2.6.11 Compliance With NFPA Codes And Standards National Fire Protection Association (NFPA) codes in effect at the time of plant design were used as guidelines in the design of passive fire protection features (e.g., fire doors, and dampers), active fire protection systems (i.e., fire suppression and detection systems), and in the development of administrative controls of fire hazards. Unique situations and configurations that deviate from applicable NFPA codes exist. However, these situations and configurations have been justified or accepted by the insurance carrier (NEIL).

The following list identifies the applicable NFPA codes:

Amendment 13, July 2013 I ZION STATION FIRE PROTECTION REPORT 2.7 ADMINISTRATIVE TECHNICAL REQUIREMENTS Fire systems are intended to be operational at all times. Outages of fire systems occur due to impairments, planned maintenance and testing. Administrative Technical Requirements have been established to place administrative controls on fire impairments.

The Administrative Technical Requirements are intended to establish the baseline for system requirements. These requirements are located in the fire protection administration procedures.

These ATRs ensure that proper compensatory measures are established for system outages and that the outage is kept to a minimum length of time. These procedures also outline the reporting requirements for system impairments to the property insurance carrier.

Each surveillance requirement shall be performed within the specified surveillance interval with a maximum allowable extension not exceeding 25 percent of the specified surveillance interval.

As the Plant systems are deactivated and fire hazards are reduced, the associated fire protection systems may be deactivated if they do not reduce the effectiveness of the Fire Protection Program. System deactivation is controlled by Plant procedures. When ATR compliance is not met, the station corrective action program is involved per approved station procedures.

The ATRs can be found in ZAP 900-01.

2.8 FHA ASSUMPTIONS AND METHODOLOGY The fire hazards analysis has been developed with the following assumptions.

a. Fire areas are designated, based on as-built conditions, as those portions of a building which are separated from other areas by physical boundaries whose construction is comparable to that of a rated fire barrier. The intent of physically impeding the spread of a fire is satisfied based on the relatively low fire loading which exists throughout the plant and the adequacy of the barriers due to other design considerations (e.g., radiation shielding, tornado, seismic). Fire barriers that existed during the SAFSTOR period and prior to the onset of decommissioning have been maintained as rated barriers. During decommissioning, fire barriers will be systematically removed to allow for the removal of equipment and debri, Including combustibles. This process will be controlled such that dismantlement of fire areas and the associated removal of combustibles within the Radiological Control Areas (RCA), will not result in a significant increase in equivalent fire severity or the accumulation of combustibles that could result in a radiological hazard. As shown by calculation (Reference 2.8.3.j), without crediting internal fire barriers, the resultant combination of fire loading for all fire zones and areas of each elevation of the AB, does not result in the possibility of a Radiological Hazard. The total equivalent fire severity for all zones combined for each elevation of the AB is shown in Table 2.8.1. Equivalent Fire Severity for the Containments was also calculated as one area. The equivalent fire severity shown for each elevation of the AB is based on all combustibles moved to the general area with the associated internal barriers removed (a typical sequence of activities for decommissioning). Periodic inspections of these fire barriers will be suspended; maintenance of structures that form ventilation barriers between the RCA and the environment will be retained as necessary.

2-15

Amendment 13, July2013 I ZION STATION FIRE PROTECTION REPORT

b. For the purpose of facilitating decommissioning, the fire hazards analysis assumes that the movement and ultimate removal of fire loads described in the FHA will result in the fire loading to temporarily Increase In adjacent fire zones and other fire zones enroute to removal of the fire loads.

This assumption is included as an Administrative Transient Combustible Load. Administrative controls are established to control the amounts, the movement, and temporary storage of these combustibles. General considerations are described below:.

Fire loads in non-radiological zones may be moved into other non-radiological zones under the direction of the Fire Marshall and Transient Fire Load administrative guidance. Fire loads in these zones do not present the potential for a Radiological Hazard. The total accumulated fire load will be controlled by administrative requirements under the direction of the Fire Marshall.

Fire loads in radiological zones may be moved into other fire zones within the Radiological Control Area (RCA) provided that the resultant fire load and associated contamination does not result in a Radiological Hazard. Administrative controls are established to ensure the amounts, the movement, and temporary storage of contaminated fire loads does not result in a Radiological Hazard. (Reference 2.8.3.j)

c. The calculation of fire loads in a given fire zone is accomplished by calculating the average combustible loading in a fire zone. This provides a quantitative measure of a fire hazard.

d. The design-basis fire is the most severe fire that can credibly occur within a fire area or zone. Fire initiation is assumed along with the failure of existing automatic protection systems, except for those systems that were installed to prevent fire spread between areas. Failure of all cables and equipment within a fire zone or area is postulated.

e. Fire Zones are outlined by the physical barriers that exist for each zone; these zones are defined as:

(1) each elevation of the AB is considered a fire zone, (2) each Containment is considered a fire zone, (3) the FB is considered a fire zone, and (4) other specific fire zones as specified In Table 2.8.1.

f. The gaskets and sealant between joints in the HVAC ductwork contribute less than 2000 Btu/ft2 and have not been considered as a combustible. (Calculation No. 22R-B-217M-003) 2-1 5a I

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT To establish a conservative approach to controlling transient combustibles, an administrative transient combustible load is defined for each fire zone. The administrative transient load applied to most of the fire zones was assumed to be the equivalent of one 55 gallon drum of lube oil per 1000 square feet of floor or 8,525 Btu/ft2 , although larger transient loads are assumed in some areas to allow for decommissioningactivities.

2.8.1 FIRE ZONE AND FIRE SEVERITY IDENTIFICATION The Radiologically Controlled Area (RCA) of Zion Station (the AB, Containments and FB) is subdivided Into 9 major fire zones. The major fire zones are Identified as: each elevation (6) of the AB, the FB, and the 2 Containments. These fire zones were previously identified as fire areas with the identification of their boundaries based on the substantial natural separation and/or structural barriers present. Due to the onset of decommissioning, all Interior structural barriers that were previously rated as fire barriers will no longer be maintained (except those barriers retained as shown in Figures 2-1 through 2-14). The rooms previously identified as a fire area are now considered a fire zone although the physical structure of the barriers still exist As denoted in Table 2.8.1 and shown on Figures 2-1 through 2-14, some fire barriers are being retained during decommissioning until combustibles and/or the potential for the spread of a fire is reduced.

All fire barriers have been derated within the TB. The description in the FHA analysis presented in Section 3 has not been revised to delineate between fire areas and fire zones. This is purposely done to Identify those structural barriers that were previously considered rated fire barriers.

The following sections describe the criteria and methodology used to identify fire areas and fire zones for Zion Station. The methodology used to develop the equivalent fire severities for each zone of a fire area is also discussed.

2-16

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT 2.8.1.2 Identification of Fire Areas and Fire Zones Prior to permanent shutdown, the plant had been subdivided into major fire areas based on existing features of construction. Based on the definition for fire area and the criteria contained in Generic Letter 83-33, 48 interior and 5 exterior fire areas were identified at Zion Station. These 53 fire areas are made up of 133 interior and 5 exterior fire zones, either individually or in combination. The fire areas were separated either by distance or by noncombustible, unrated fire barriers. These divisions were generally retained during the SAFSTOR period. With the onset of decommissioning, all fire areas have been redesignated as fire zones.

Based on the amount and type of combustibles, many of the previously designated fire zones within the RCA have been combined into one fire zone with the Equivalent Fire Severity recalculated for that combination of zones. The original Fire Zone identifier has been retained for simplicity. Fire Zones that have been combined are identified with the original designation in parenthesis. For example, Fire Zone 11.1 is the 542' elevation of the AB; (11.1 A-1) designates the RHR pump room within Fire Zone 11.1.

The main criterion for downgrading fire barriers (that were previously maintained during SAFSTOR) inside the RCA to unrated barriers Is based on the floor area and the type of combustibles present. As most of the combustible load within interior rooms is cable insulation, the propagation of a fire from those areas Is highly unlikely. This is due to the IEEE 383 requirement for the insulation to be self extinguishing. The areas within the RCA that contain relatively significant amounts of combustibles, based on fire load and severity, other than cable are: (1) the general floor areas of the AB and the Containments, which are very large areas and combustibles are significantly spread out, (2) the U1 & U2 Containment Purge Equipment Rooms, and (3) the RP Offices & Lab areas. The fire severities of these areas are each less than 32 minutes. Maintenance and inspections of some of the barriers associated with these areas and other specific areas will remain in effect until the associated fire load has been sufficiently reduced such that the onset and spread of a fire across the unrated barriers is highly unlikely. Figures 2-1 through 2-14 identify fire barriers that are being maintained.

Exterior walls of the RCA serve as a ventilation boundary. As such, most of the exterior walls will remain intact until final demolition of the building.

The fire zones are listed in Table 2.8.1. The fire detection and suppression systems are also identified and listed in Table 2.8.2 on a zone-by-zone basis.

2.8.1.3 Equivalent Fire Severities The equivalent fire severities and combustible loadings for each zone of the fire areas listed in Table 2.8.1 are based on an inventory of exposed cable insulation (i.e., not in conduit), paper, wood, lubricating oil, diesel fuel, charcoal filters, and maintenance supplies (up to 1000 Btu/ib). The 16th edition of the National Fire Protection Association's Fire Protection Handbook provides guidance on converting weights of various materials into estimated minutes of bum time.

2-20

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT Equivalent fire severity in minutes is calculated by multiplying fire load in Btu/ft2 by 7.5 x 104 min/Btulft2 and rounding to the nearest minute to give the equivalent fire severity on the ASTM E-1 19 standard time-temperature curve assuming total combustion of the fuels. In areas where the equivalent fire severity is greater than 180 minutes, it will be restated as >3 hours.

Fire areas and zones, along with a description of fire protection features and combustible loads, are listed in Table 2.8.1.

For example, the equivalent fire severity resulting from the total consumption of 2000 lb of charcoal (with a heat of combustion of 15,000 BtuMlb) located in a fire zone with a floor area of 200 ft2 would be:

2000 lb / 200 ft x 15,000 Btu/lb =

150,000 Btu/tt2 which has an equivalent fire severity of:

150.000 Btu/I/ 1333 Btuft2/minute =

113 minutes (It should be noted that the value of 1333 Btu/ft 2/minute is linear for equivalent fire severities of up to 4.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months in duration.)

This analysis has been performed for each interior fire zone in Table 2.8.1, with the equivalent fire severities Wsted in the table. The above procedure was used in developing and documenting the fire loading and fire severity in each fire zone/fire area.

2-20a I

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT 2.8.1.4 Assumptions The combustible materials and their location within each fire zone have been identified by reviewing design drawings and vendor drawings data. Field verification has been performed as needed. The following assumptions were used in developing combustible loads:

a. Combustibles associated with the insulation and lubrication of bearings inside each motor are negligible and were not considered.

b. Combustibles associated with cable insulation of conductors that are in rigid conduit are negligible and were not considered.

c. The only combustibles considered in any of the control panels, switchgear, and motor control centers is the cable insulation. Any other combustibles that may be present in these panels, etc., are considered negligible and, therefore, were not considered.

d. Insulation of cables contained in each section of 480-V MCCs and 4160-V switchgear shall be estimated to weigh 20 pounds.

e. Insulation of cables contained in each 20 inches of lateral length of a control panel shag be estimated to weigh 50 pounds. Insulation of cables contained in each 20 inches of lateral length of local miscellaneous panels (excluding instrument racks) shall be estimated to weigh 32 pounds.

Insulation of cables contained In each 20 inches of lateral length of an instrumentation or computer panel shall be estimated to weigh 30 pounds.

f. Insulation of cables contained in each section of 480-V switchgear is estimated to weigh 40 pounds.

g. The combustion characteristics of both the cable Insulation and jacketing materials are the same.

h. Using the defined fire zones, the cable tray fire loading has been determined as follows:

1. Tabulate all of the. routing points which run through the fire zone/fire area being analyzed.

This tabulation shall include the routing points for all power, control, and instrumentation tray, covered or uncovered, horizontal tray or riser.

2. Determine the number of cables passing through the routing point and the length of each routing point.

3. For each fire zone, provide a volume in ftW of cable insulation for power, control cables, and also for instrumentation cables using conversion factors.

The exemption requests were revised by ComEd in 1992 to reflect Increases infixed combustible loading that had occurred since the 1982 and 1987 exemption request submittals. In the SER, the NRC stated that although the fixed combustible loading had increased, revised exemptions were not required because the basis for acceptance of the original exemptions had not changed. The SER does not specifically quote all the values listed in this column; however, the SER states that the NRC review was based on combustible loading values staled In the FPR dated 09/15/92, Therefore, the values in this column reflect those listed in the 09/15/92 FPR.

Note 2: General Area 11.1-0 Includes combustibles from areas 11.1E-1, 11.1E-2, 11.1F-1. 11.1F-2. 11.IG-1, 11.1G-2, 11.1H-1 and 11.1H-2 as depictedIn reference"h". The fire load and severity shown for the General Area of the 542' elevation of the AB 11.1-0 Include these areas. I Note 3: Fire Barriers are being maintained In these zones due to the type of combustibles present and/or the potential for a fire to spread Into the RCA.

Amendment 13, July2013 i ZION STATION FIRE PROTECTION REPORT 3.0 FIRE HAZARD ANALYSIS The FHA analysis presented in this section refers to fire barriers that existed prior to the onset of decommissioning. Based on the amount and type of combustibles present within the interior rooms of the RCA, and the low amount of combustibles outside of the RCA, the existing fire barriers of most areas have be downgraded to unrated barriers. Actual removal of barriers will not occur until the onset of decommissioning for the associated zone.

In summary, areas previously designated as Fire Areas will be designated as Fire Zones due to the suspension of maintenance and periodic inspections of fire barriers except as denoted in Tables 2.8.1 and Figures 2-1 through 2-14. All previous designations of Fire Zones will remain the same; Fire Zones and fire barriers are shown on Figures 2-1 to 2-14.

3.0.a Containment Buildings The primary containment for each unit is considered a fire zone and has been divided into four segments for the assessment of fire loading. The following discussion applies to the fire analysis of the entire containment structure for each unit.

Each primary containment building is a closed concrete cylinder with structural reinforced base slab, walls, and a domed roof slab. These elements vary In thickness from 32 inches for the roof to 108 inches for the base slab. The roof slab and walls have been post-tensioned by means of steel tendons. The inside face of the entire building is lined with a 14-inch thick steel plate liner.

During decommissioning, access to the containment building will be through the 222-inch-diameter steel "equipment" air lock which leads to the Auxiliary Building at elevation 617 feet 0 inch. Each containment has a Construction door installed for bringing in equipment and removal of debris. With the exception of these entry points, the base slab, walls, and roof slab carry a minimum fire rating of 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months .

Electrical cable penetrations and mechanical piping penetrations are provided. These penetrations have not been tested as fire barriers but would prevent the propagation of any fire likely to start into or out of the primary containment.

Radiological Hazard Potential Radiation and contaminants are present in all areas of the containment. The release of airborne radioactivity is controlled by maintaining the containment atmosphere negative in pressure with respect to the outside environment's atmospheric pressure. This negative pressure is maintained by the AB Ventilation system and/or Containment Purge system. Air can be exhausted from containment through the Containment Purge Exhaust Fans. Air can also be extracted from the containment through the equipment hatch to the AB. The AB Exhaust Fans can maintain the AB and the containments negative in pressure when the construction doors are closed. Administrative controls maintain the Containment Purge exhaust fan in operation when the construction doors are open. The AB Ventilation and the Containment Purge system use prefilters and HEPA filters to filter out any high radiation contaminants.

The exhaust air is routed to the vent stacks and is monitored for gaseous and particulate radioactive via radiation monitors. Portable CO 2 or dry chemical extinguishers are recommended for any fire in this zone due to radiation conditions. Manual fire suppression is also available via hose stations located inside the containments.

Equipment Important to the Defueled Condition (ITDC)

The following equipment in the containments is important to the defueled condition:

Containment Purge System 3-1

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT Fire Protection Criteria and Measures There are no automatic suppression or detection systems in the Containments. However, manual fire suppression equipment Including portable fire extinguishers and dry standpipe hose stations are available for fire responder use. The dry standpipe hose stations will be made ready for use for the ZMFD by the Local Operator (or the Shift Supervisor) in the event of a fire. Access routes are available to fire response personnel responding to a fire in this fire area. Smoke removal capability can be provided by the containment purge system through HEPA filters.

Design-Basis Fire The design-basis fire would result if cable insulation in a zone burned. It could also spread to the other zones inside the containment since the walls and floors separating these zones are not designated as fire barriers. The fire would not spread beyond the containment due to the containment walls and the large separation from combustibles outside of the containments.

The design-basis fire is unlikely for the following reasons:

Hot work associated with the dismantlement and removal of equipment inside the containments will be reviewed by the Fire Marshall for Fire Watch requirements. Combustibles will be removed as part of the dismantlement.

No significant quantities of combustible material that is easily ignited are stored in this area. Most of the combustibles material is cable insulation that meets the IEEE 383 criteria for cable fire tests.

" The fire zones have a low fire loading and the combustibles present are not evenly distributed, making the likelihood of a fire spreading to the other zones within the containments small.

3.0.1 Unit 1 Containment 1.0-1 This fire zone is comprised of the following segments:

1.1-1 Unit 1 reactor cavity, 1.2-1 Unit 1 Annular area, elevations 590 ft and 568 ft, 1.3-1 Unit 1 steam generator and reactor coolant pump area, and 1.4-1 Unit 1 operating floor, elevation 617 ft.

3-1a

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT Combustible Material and Fire Loading The combustible material in this fire area consisted of 104 gallons of lube oil (which has been drained),

about 420 lb of cable Insulation In trays and cabinets, about 48 ft of nuclear instrumentation cable, about 35 lb of flexible connectors (HVAC), 18 modules each of HEPA and pre-fihters, and 2688 lb of wood. With a floor area of 12,266 ft2 and a total heat content of 5.129 x 107 Btu, the average fire loading in this area is about 4.182 x 10 3 Btu/ft2 with an equivalent fire severity of 3 minutes.

The administrative transient combustible load limit for this fire zone is 8,525 Btu/ft 2.

3-9

Amendment 13, July2013 I ZION STATION FIRE PROTECTION REPORT 3.0.2 Unit 2 Containment 1.0-2 This fire zone is comprised of the following segments:

1.1-2 Unit 2 reactor cavity,

.1.2-2 Unit 2 Annular area, elevations 590 ft and 568 ft.

1.3-2 Unit 2 steam generator and reactor coolant pump area, and 1.4-2 Unit 2 operating floor, elevation 617 ft.

3.0.2.1 Unit 2 Reactor Cavity (1.2-1 Fire Barrier Description A structural reinforced concrete cylinder surrounds the rough reactor cavity. Access to the steam generator area at elevation 568 feet 0 inch from the reactor cavity is through a solid door to a tunnel. Both the rough tunnel and rough reactor cavity are provided with 'A-inch-thick steel liner plate.

A. Floor The structural reinforced concrete slab below this cylinder, which Is the base slab of the containment building, is 53 feet 0 inch in diameter, and 108 inches thick. There are no floor drains in the reactor cavity or tunnel floor. A stainless steel sump with pump is located in the tunnel floor for the purpose of removing water to another sump on the reactor floor at elevation 568 feet 0 inch.

B. Ceiling The domed roof slab is constructed of structurally reinforced concrete.

C. Wall A structural reinforced concrete cylinder with an inside diameter of 21 feet 0 inch and walls 16 feet 0 inch thick surround the rough reactor cavity from elevation 539 feet 0 inch up to elevation 565 feet 0 inch.

The rough tunnel walls are structural reinforced concrete 36 inches thick.

Over the rough structural concrete described above are placed 24-inch-thick (reactor cavity walls), 30-inch-thick (reactor cavity and tunnel floor), and 15-inch-thick (tunnel walls) structural reinforced concrete finish slabs.

From elevation 565 feet 0 inch to elevation 580 feet 6 inches, a structural reinforced concrete cylinder with an inside diameter of 17 feet 1 inch and walls 101 inches thick surround the reactor cavity.

From elevation 580 feet 6 inches to elevation 590 feet 5-1/2 inches or elevation 589 feet 5-1/2 inches, a structural reinforced concrete cylinder of 25 feet 0 inch inside diameter and 54 inches thick surrounds the reactor cavity.

Finish concrete 8 inches thick is placed over the structural reinforced concrete to elevation 590 feet 5-1/2 inches or elevation 589 feet 5-1/2 inches.

A 1-foot-0-inch thick concrete cylinder of inside diameter 18 feet 6 inches is placed around the circumference of the reactor at elevation 591 feet 1-1/2 inches. Between this cylinder and the structural reinforced concrete cylinder at elevation 591 feet 1.1/2 inches are eight access panels of 12-gauge steel-plate covered with bricks made of shielding material.

Penetrations through the structure surrounding the reactor vessel for steam and feedwater piping are sealed with noncombustible material. The tunnel opening to the steam generator area at elevation 508 feet 0 inch is provided with non-fire-rated doors.

These walls, ceiling, and floor are not designated as fire area barriers.

3-10

Amendment 13, July2013 ZION STATION FIRE PROTECTION REPORT 3.0.2.4 Unit 2 oeratirn Floor. Elevation 617 (1.4-21 Fire Barrier Description This zone includes the entire containment building from elevation 617 feet 0 inch up to the domed roof slab at elevation 779 feet 8 inches, and the refueling cavity from elevation 581 feet 0 inch up to elevation 617 feet 0 inch. This zone is constructed of reinforced concrete with open stairwells and grated openings to the level below.

A. Floor The floor at elevation 617 feet 0 inch is a 36-inch structural reinforced concrete slab in the portion over the steam generator and reactor coolant pump area and has a number of penetrations for equipment. The remaining portion, which Is over an annular area, is steel grating supported on exposed steel framing.

Floor drains are routed to a sump at elevation 568 feet 0 inch.

B. Ceiling A domed roof slab constructed of structural reinforced concrete covers this zone.

C. Wall The 9-foot-0-inch high by 30-inch-thick structural reinforced concrete walls completely surround the top portion of the four steam generators that project above the floor slab at elevation 617 feet 0 inch. In addition, the pressurizer is enclosed by 12-inch-thick structural reinforced concrete walls that are capped by a removable 12-inch-thick structural reinforced concrete roof slab at elevation 655 feet 8 inches. HVAC ducts are not provided with fire dampers.

Radiological Hazard Potential Radiation and contaminants are present in this area. Air is exhausted from containment through prefilters and HEPA filters to filter out any high radiation contaminants. The air is then routed to the vent stacks via exhaust fans. Portable C02 or dry chemical extinguishers are recommended for any fire in this zone due to radiation conditions and distances from hose stations. Personnel doses should be monitored in this area.

3-16

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT Combustible Material and Fire Loading The combustible material in this fire area consisted of cable insulation in trays and cabinets, nuclear instrumentation cable, flexible connectors (HVAC), HEPA and pre-filters, wood, plastic battery casings.

With a floor area of 12,266 ft2 and a total heat content of 6.09 x 107 Btu, the average fire loading in this area is about 4.968 Btu/ft2 with an equivalent fire severity of 4 minutes. The administrative transient combustible load limit for this fire zone is 8,525 Btu/ft2 .

Fire Protection Criteria and Measures This fire zone has no general area automatic fire suppression or detection.

Manual fire suppression equipment including portable fire extinguishers and hose stations are available at containment entry for fire responder use. Access routes to this fire zone are available for responding fire response personnel.

Design-Basis Fire The design-basis fire would result if the combustible materials in this zone burned. This fire could spread to other zones in the containment, since the zone boundaries are not designated as fire barriers, but it would not spread out of the containment building.

The design-basis fire is unlikely, since this zone has a low fire loading, and the combustibles present are not evenly distributed, making the likelihood of a fire spreading rather small.

Any fire likely to start in this zone would remain confined to a small area, and would not cause any major damage.

3-17

Amendment 13, July 2013 ZION STATION FIRE PROTECTION REPORT Radiological Hazard Potential A fire in this area would not create a radiological hazard for the following reasons:

This area contains no significant radiological material or contamination. This area is separated from radiological areas by fire barriers.

Fire Protection Criteria and Measures Fire detection in this fire zone is provided by ionization smoke detectors that alarm in the control room.

Manual fire suppression equipment in the form of portable fire extinguishers and hose stations is available in this fire zone and/or in adjacent fire areas/zones. Access routes are available to fire response members responding to a fire in this zone.

Design-Basis Fire The design-basis fire would result if all of the cable insulation in the room burned. Control of equipment located in rooms would be lost. Since all of the rooms on the floor are either sealed or contain negligible amounts of combustible materials, the fire would not enter those areas. The air would be filtered before it is released. The design-basis fire could spread to other floors, since the floor and ceiling do not qualify as fire barriers.

The design-basis fire is highly unlikely, since most of the combustible material present is cable insulation.

In addition, the cables are separated in cable trays by function and division.

A fire in this area does not cause a radiological hazard in the Auxiliary Building.
