Diverse and Flexible Coping Strateg ies (FLEX) Overall Integrated Implementation Plan (55 pages)

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 1 of 55 General Integrated Plan Elements (JAF) Determine Applicable Extreme External Hazard Ref: NEI 12-06 Sections 4.0 - 9.0 JLD-ISG-2012-01 Section 1.0 Input the hazards applicable to th e site; seismic, external flood, high winds, snow, ice, cold, high temps.

Describe how NEI 12-06 Sections 5 - 9 were applied and the basis for why the plant screened out for certain hazards. The extreme external hazards were grouped into five classes in NEI 12-06, Section 4.1. The classes of hazards determined to be applicable to the James A. FitzPatrick Nuclear Power Plant (JAF) are seismic, extreme cold, high winds and high temperature as detailed below:

Seismic Hazard Assessment: The seismic design for Class I structures and equipment is based on dynamic analysis using acceleration response spectrum curves normalized to a ground motion of 0.08g for the Operating Basis Earthquake and 0.15g for the Design Basis Earthquake. The basis for these criteria is presented in the JAF Final Safety Analysis Re port (FSAR) (Reference

1) Section 2.6. Per NEI 12-06 (Reference 2, Section 5.2), all sites will consider the seismic hazard. Thus the seismic hazard is applicable to JAF. External Flood Hazard Assessment:

JAF is built above the design basis flood level. Per JAF FSAR (Reference 1, Sections 2.4.3.2 and 2.4.3.7), the Probable Maximum Flood (PMF) elevation at the screenwell is 255 ft. This is based on a maximum lake level of El 250', and considers the setup (4.1') and maximum precipitation (0.35'). The maximum probable flood lake level is determined considering the maximum lake level, a maximum wind setup of 4.1 feet, the maximum rainfall of 0.35 feet and a maximum wave run-up height of 7.5 feet; this results in a maximum probable flood la ke level of just under 262'. The grade elevation at JAF is 272 ft (Reference 1, Se ction 2.4.3.7). Therefore, JAF is built above the design basis flood level and is considered a "dry

" site by the NEI guidanc e (Reference 2, Section 6.2.1) and "dry" sites are not required to evaluate flood-induced challenges.

Thus external flood hazard screens out as not applicable to JAF. Extreme Cold Temperature Hazard Assessment:

JAF is located above the 35 th parallel at coordinates North 4,819,545.012 m, East 386,968.945 m on the Universal Transverse Mercator system (Reference 1, Section 2.1.1) (43.503

° N latitude, 76.435° W longitude (Reference 4)) and is subject to the extreme cold hazards, including snow and ice. The site is located within the region characterized by NOAA as subject to significant accumulations during three-day snowfalls (see Reference 2, Figure 8-1.) The site is located within the region characterized by EPRI as ice severity level 5 (Reference 2, Figure 8-2.) As such, the JAF site is subject to severe icing conditions that could also cause catastrophic destruction to electrical transmission lines. Thus the extreme cold hazard, including snow and ice, is applicable to JAF.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 2 of 55 General Integrated Plan Elements (JAF) High Wind Hazard Assessment:

JAF is located above the 35 th parallel. As indicated in NEI 12-06 Figure 7-1, hurricane winds in excess of 130 mph are not expected to occur at JAF. However, per the NEI 12-06 Figure 7-2, a recommended design tornado wind speed of 169 mph is identified. Thus the high wind hazard (169 mph tornado winds) is applicable to JAF. Extreme High Temperature Hazard Assessment:

Per NEI 12-06 Section 9.2, all sites will address high temperatures. Extreme high temperatures are not expected to impact the utilization of off-site resource s or the ability of personnel to implement the required FLEX strategies. Site industrial safety procedures currently address activities with a potential fo r heat stress to prevent adverse impacts on personnel. Thus the high temperature hazard is applicable to JAF. Summary of the extreme external hazards assessment: The hazards applicable to JAF are seismic, extreme cold, high wind and high temperature.

Key Site assumptions to implement NEI 12-06 strategies.

Ref: NEI 12-06 section 3.2.1 Provide key assumptions associated with implementation of FLEX Strategies: Flood and seismic re-evaluati ons pursuant to the 10 CFR 50.54(f) letter of March 12, 2012 are not completed and

therefore not assumed in this submittal. As the re-

evaluations are completed, appropriate issues will be

entered into the corrective action system and addressed on a schedule commensurate with ot her licensing bases changes. Exceptions for the site security plan or other (license/site specific) requirements of 10CFR may be required. Deployment resources are a ssumed to begin arriving at hour 6 and fully staffed by 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . Certain Technical Specificati ons cannot be complied with during FLEX implementation.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 3 of 55 General Integrated Plan Elements (JAF) Key assumptions considered in the development and implementation of FLEX Strategies for JAF are described below: Flood and seismic re-evaluations pursuant to the 10 CFR 50.54(f)

Letter of March 12, 2012 are not completed and therefore not assumed in this submittal. As the re-evaluations are completed, appropriate issues will be entered into the corrective action system and addressed. The following conditions exis t for the baseline case:

o Seismically designed DC battery banks are available.

o Seismically designed AC and DC distribution systems are available.

o Plant initial response is the same as Station Blackout (SBO) event.

o Best estimate analysis and decay heat is used to establish operator time and action.

o No single failure of SSC assumed (except those defined in the Order, i.e., EDG operation and motive force for the Ultimate Heat Sink pumps.) Therefore, RCIC will perform either via automatic control or with manual operation capability per the guidance in NEI 12-06. Portable FLEX components wi ll be procured commercially.

The designed hardened connections are protected against external events or are established at multiple and diverse locations.

Deployment strategies and deployment routes are assessed for hazards impact. FLEX components will be designe d to be capable of performing in response to screened in hazards in accordance with NEI 12-06. Margin will be added to the design of the FLEX components and hard connection points to address future requirements as re-evaluation warrants. This margin will be determined during the detailed design or evaluation process. Phase 2 FLEX components stored at the site will be protected against the applicable hazards in accordance with NEI 12-06. At least one set of FLEX equipment will be available after the event they were designed to mitigate. Backup Phase 2 FLEX equipment will be provided by the Regional Response Center. Phase 3 FLEX equipment will be provided by the Regional Response Center (RRC). Additional staff resources are expected to begin arriving at 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and the site will be fully staffed 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months after the event. Maximum environmental room temperatures for accessibility or equipment availability are based on NUMARC 87-00 (Reference 1) guidance if other design basis information or industry guidance is not available.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 4 of 55 General Integrated Plan Elements (JAF) This plan defines strategies capable of mitigating a simultaneous loss of all AC power and loss of normal access to the UHS resulting from a beyond design basis external event (BDBEE) by providing adequate capability to maintain or restore core cooling, containment, and SFP cooling capabilities at all units on a site. Though sp ecific strategies are being developed, due to the inability to anticipate all possible scenarios, the strategies are also diverse and flexible to encompass a wide ra nge of possible conditions. These pre-planned strategies developed to protect the public health and safety will be incorporated into the unit guidance. The plant TSs contain the limiting conditions for normal unit operations to ensure that design safety features are available to re spond to a design-basis accident and direct the required actions to be taken when the limiting conditions are not met. The result of the BDBEE may place the plant in a condition where it cannot comply with certain TSs and/or with its Security Plan, and, as such, may wa rrant invocation of 10 CFR 50.54(x) and/or 10 CFR 73.55(p). (Reference 2).

Exceptions for the site security plan or other (license/site specific) requirements of a nature requiring NRC approval will be communicated in a future 6-month update following their identification. There are two OPEN ITEMs for which Entergy does not have clear guidance to complete an action related to this submittal, as noted below:

1. Beyond-design-basis external event impact on requirements in existing licensing documents will be determined based on input from the industry groups and direction from the NRC. 2. The structure, content and details of the Regional Response Center playbook will be determined.

Entergy has no known deviations to the guidelines in JLD-ISG-2012-01 and NEI 12-06 for the FLEX implementation at JAF

. If deviations are identified in the future, they will be communicated in a future 6-month update following identification.

Provide a sequence of events and identify any time

constraint required for

success including the technical basis for the time

constraint.

Ref: NEI 12-06 section 3.2.1.7 JLD-ISG-2012-01 section 2.1 Strategies that have a time constrai nt to be successful should be identified with a technical basis and a justification provided that the time can reasonably be met (f or example, a walkthrough of deployment).

Describe in detail in this secti on the technical bas is for the time constraint identified on the sequence of events timeline A. See attached sequence of events timeline (Attachment 1A).

Technical Basis Support information, see attached NSSS Significant Reference Analysis Deviation Table (Attachment 1B).

A sequence of events during the FLEX scenario is provided in Attachment 1A. Those events for which a new extended loss of AC power (ELAP) tim e constraint is noted are discussed further below. 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months - Determination that situation is a BDBEE. The Shift Manager or Control Room Supervisor determines that the plant condition is a FLEX scenario and enters the appropriate procedures. A time period of one (1) hr ha s been conservatively selected to allow assessment of plant conditions and determine that the Station Blackout situation could be an extended loss of AC power event (ELAP), which will drive the implementation of certain

strategies designed to preserve key event res ponse resources like the batteries and make-up water. This includes consideration of the availability of the emergency diesel generators.

One hour is a reasonable assumption for system operators to perform initial evaluation of the EDGs. Entry into ELAP procedures provides guidance to operators to perform ELAP actions, including deployment of FLEX resources. 90 minutes - DC Load shed complete. FLEX response procedures will detail the actions necessary. DC buses are readily available for operator access and breakers will be appropriately identified (labeled) to show which are required to be opened to affect a deep load shed. Based on engineering judgment, it is reasonable to expect that operators can complete the shedding of loads from the DC bus in approximately 30 minutes. 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months - Take action to avoid operation in the Unsafe Region of the heat capacity temperature limit (HCTL) curve (Reference 2). The action involved is to take manual control of the SRVs and depressurize the react or pressure vessel, a nd achieve a pressure band of between approximately 200 psig and 400 ps ig. This event is predicted to occur at about 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months by analysis (Referen ce 8); it will be driven by ac tual plant response during the James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 6 of 55 General Integrated Plan Elements (JAF) event. It becomes time critical at the point of entering the Unsafe Region of the HCTL curve. Manual control of the SRVs is performed from the control room with sufficient DC power and pneumatic pressure to operate the SRVs throughout Phase 1.

10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months - Re-power a battery charger to maintain the DC Power System. Deployment of the FLEX DG will be initiated shortly after the BDBEE is d eclared in recognition of the potential for battery depletion. The event is tim e critical at battery de pletion; both the A and the B batteries (71SB-1 and 71SB-2) have been calculated to last more than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in the FLEX scenario (Reference 11). The FLEX DG will be maintained in on-site FLEX storage buildings. The FLEX DG will be transferred and staged via haul routes and staging areas evaluated for impact from external hazards (Reference 4). Modifications required to facilitate repowering DC buses will be determined during the detailed design process and will follow NEI 12-06 guidance. Modifications to DC Buses and to the exterior of appropriate buildings will be implemented to facilitate the connections and operational actions required to re-power the battery charger (71BC-1A or 71BC-1B) (Reference 5). Programs and training will be implemented to support operation of FLEX DGs. 23 Hours - Initiate use of the Reliable Hardened Vent System (RHVS). This action will be accomplished in accordance with EOPs to maintain containment parameters within acceptable limits and within the limits that support continued use of the RCIC system. The operators will open the wetwell vent and the RHVS to relieve pressu re conditions in the wetwell/drywell. Operation of RHVS is performed from the Relay Room and can be accomplished because the RHVS is seismically rugged, DC-powered (backed by batteries), and provided with adequate nitrogen Containment Atmospheric Dilution (CAD) system, backed up by portable gas bottles for the ELAP event. Critical instruments associated with containment and the RHVS are DC-powered and can be read in the Relay Room. (Reference 7) 34 hours3.935185e-4 days 0.00944 hours 5.621693e-5 weeks 1.2937e-5 months - As the CST volume is depleted, the seismically qualified diesel-driven fire pump will be aligned to continue providing makeup to the RPV. This timing is based on the minimum qualified volume of water in the CST; this event may be later if additional volume in the CST survives the event. This flow path is established using a temporary hose at an existing cross-connect between the fire protection system and the RHR Service Water system (at valve 10RHR-432.) See the Mainta in Core Cooling Phase 2 discussion below. Technical Basis Support information

1. On behalf of the Boiling Water Reactor Owners Group (BWROG), GE-Hitachi (GEH) developed a document (NEDC-33771P , Revision 0 (Reference 4)) to supplement the guidance in NEI 12-06 by providing additional BWR-specific information regarding the individual plant response to the BDBEE (i.e., Extended Loss of AC Power (ELAP) and loss of Ultimate Heat Sink (LUHS).) The document includes the id entification of the generic event scenario and expected plant response, the associated analytical bases and recommended actions for performance of a site-specific gap analysis. In the document, GEH utilized the NRC-accepted SUPERHEX (SHEX) computer code met hodology for the BWR long-term containment analysis for the ELAP analysis. As part of this document, a generic BWR 4/Mark I containment NSSS evaluation was performed. The generic BWR 4/Mark I containment James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 7 of 55 General Integrated Plan Elements (JAF) analysis is generally applicable to the JAF (a BWR 4/Mark I plant) coping strategy because it supplements the guidance in NEI 12-06 by providing BWR-specific information regarding plant response for core cooling and containm ent integrity. The guidance provided in the BWROG report was utilized as a ppropriate to develop coping st rategies and for prediction of the plant's response. 2. JAF containment integrity for Phases 1 th rough 3 was evaluated by analysis using the computer code MAAP 4.05 (References 8 and 12).

3. A bounding decay heat management analysis considered the fuel decay heat load curve in both the reactor vessel and the fuel moved to the spent fuel pool. (JAF-CALC-MISC-02373 (Reference 6))

4. Environmental conditions within the station areas were evaluated utilizing methods and tools in NUMARC 87-00 (Reference 10) or Gothic 7.2b (EPRI software) (Reference 13).

5. Per the guidance in 10 CFR 50.63 and Regulatory Guide 1.155, JAF is a 4-hr coping plant for Station Blackout (SBO) considerat ions. Applicable portions of supporting analysis have been used in ELAP evaluations (Refer ence 9, JAF FSAR Section 8.11).

Phase 1 of the FLEX strategies for core cooling, containment integrity, and spent fuel cooling will be implemented using installed equipment and on-shift personnel resources. Phase 2 of the strategies will involve the use of portable FLEX equipment that will be identified, procured, suitably stored, and whose deployment will be appropriately described in FLEX response procedures. Routes from equipment storage locations to equipment deployment locations have been identified as shown in Figure 3. Phase 3 equipment, brought in from off-site storage or procurement, will utilize the same pathways employed for the Phase 2 equipment once they are brought inside the JAF protected area. The identified paths and deployment areas will be accessible during all modes of operation. In addition the clearing of these paths following any significant external event or hazard will be handled on a priority basis. This deployment strategy will be included within an administrative program in order to keep pathways clear or actions to

clear the pathways.

documented in later sections of this template and need not be included in this section.

See section 6.0 of JLD-ISG-2012-01. JAF will implement an administrative program for implementation and maintenance of the FLEX strategies in accordance w ith NEI 12-06 guidance. Installed structures, systems and components currently designed and installed meet augmented quality guidelines (e.g., equipm ent installed to address 10CFR50.48, Fire Protection, or 10CFR50.63, Station Blackout) will continue to meet the augmented quality guidelines. JAF will utilize the standard EPRI industry PM process for establishing the maintenance actions for FLEX components. Preventive maintenance procedures will be established for portable components that directly perform in the mitigating strategy for the key FLEX safety functions (i.e., core cooling, containm ent integrity, and spent fuel cooling.) These procedures will consider NEI 12-06 guidance, vendor recommendations, and applicable industry standards. Testing procedures will be developed and performed at fr equencies established based on James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 10 of 55 General Integrated Plan Elements (JAF) type of equipment and considerations made within EPRI guidelines. A description of the programmatic controls re lated to the storage and protection of FLEX equipment is provided later in this plan document.

Describe training plan List training plans for affected organizations or describe the plan for training development New training of general station staff and the Emergency Response Organization will be performed in 2016 prior to design implementation.

Identify methods (RCIC/HPCI/IC) and strategy(ies) utilized to achieve this coping time.

Power Operation, Startup, and Hot Shutdown The primary strategy for core cooling is to supply high quality water via RCIC with suction from the torus and the CST. The design of the Condensate Storage Ta nks ensures that at least 200,000 gallons of water is available to RCIC for injection into the reactor vessel (Reference 11, Section

10.9.3). Based on Reference 3, the combination of the torus and the CST volumes are expected to be able to support reactor pressure vessel make-up for at least 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months without any replenishment of the CST. At the initiation of the BDBEE, main steam isolation valves (MSIVs) automatically close, feedwater is lost, and safety relief valves (SRVs) automatically open to control pressure, causing reactor water level to decrease. When reactor water leve l reaches 126.5 inches, low-low level 2, injection from Reactor Core Isolation Cooling (RCIC) and High Pressure Coolant Injection (HPCI) systems is initiated (Reference 1, Tables 3.3.5.1-1 (Function 3a) and 3.3.5.2-1 (Function 1), and References 7 and 8). The RCIC and HPCI pumps start with suction from the Condensate Storage Tanks (CST) and operate to inject make up/cooling water to the reactor vessel. This injection will recover the reacto r level to the high level setpoi nt of 222.5 inches (Reference 1, Tables 3.3.5.1-1 (Function 3c) and 3.3.5.2-1 (Function 2)). The SRVs ensure the reactor pressure vessel pressure will not exceed its design limits. In a typical SBO event (and in the Extended loss of AC Power (ELAP) BDBEE), RCIC is able to provide make-up and maintain reactor pressure vessel (RPV) level. On that basis, at approximately 20 minutes into the event, the operator takes action to override auto-initiation of HPCI. This helps to preserve the 'B' battery and also reduces the heat-up of the crescent area where the HPCI pump is located. Once it has been confirmed that the Emergency Di esel Generators (EDGs) cannot be started, the Shift Manager determines the event is a beyond-design-basis event; it has been assumed this decision is made within approximately one hour. Once it is determined that a BDBEE is occurring, RCIC suction will be swapped to the torus. This will enable the use of the available water in the torus before it becomes too hot to support RCIC operation. RCIC suction will be maintained on the SP until the SP temperature reaches about 170°F when it will be swapped back to the CST. This occurs approximately 5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months s into the even t (Reference 3.) Based on the experience derived from Fukushima, the RCIC system can run at a much higher lube oil James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 13 of 55 Maintain Core Cooling temperature and suction source temperature (Reference 6) than that originally assumed for the operation of RCIC. This strategy of drawing from the torus early is intended to optimize the use of qualified available water sources during the BDBEE. RCIC valves and controls that are required to reposition during this ev ent are powered by station DC power. Select RCIC trip signals and is olation signals that could possi bly prevent RCIC operation when needed during the ELAP will be overridden in accordance with procedural direction. Additionally, the automatic depressurization system (ADS) will either be placed in 'inhibit' or closely monitored to prevent automatic initiation of ADS. This is necessary to ensure reactor pressure is not reduced to a pressure that would prevent operation of RCIC.

As stated above, the primary method of reactor pressure control is by operation of the SRVs. All the safety/relief valves can be either automatically actuated by excess steam pressure or the valves can also be opened manually through remo te switches. The safety/relief valves are equipped with a nitrogen accumulator and check valve arrangement (note that 2 valves (RV-71E and RV-71F) share one accumulator and two check valves.) In addition to the accumulators, a pneumatic supply system for the ADS valves provides a reliable, safety-related, seismically qualified, 100-day supply following a design basis accident to enable long-term cooling. (Reference 11, Sections 4.4 and 5.2.3.8.4)

The torus continues to heat up due to RCIC exhaust and SRV cycling. During the time that torus temperature is increasing the operators will reduce reactor pressure to a pressure range that provides margin to the Unsafe Region of the h eat capacity temperature limit (HCTL) curve. When the temperature reaches the Unsafe Region of the HCTL, an emergency depressurization must be performed (References 9 and 10). Per recent BWR Owners Group (BWROG) guidance (Reference 2), EOPs will be revised to allow termination of RPV emergency depressurization and allow pressure to be controlled in a range that supports continued RCIC operation; the steam-driven RCIC is the preferred means of core cooling.

Regarding net positive suction head (NPSH) for RCIC, the approach currently planned for JAF draws suction from the torus only while it is relatively cool. While the BWROG is evaluating operation of the RCIC pump using fluid at temperatures of up to 230 °F, incorpora ting this into the strategy must consider availa ble NPSH at those conditions. At about 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months into the event, the average make-up flow rate is approximately 180 gpm; at about 30 hour3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months s into the event, the average make up flow needed is about 80 gpm (bas ed on Reference 3). The required suction head for the RCIC pump is 20.25 feet at 416 gpm (Reference 12); the requi red head decreases at lower flow rates. Manual flow control may provide some opportunity to utilize the torus as a suction source later in the event. The containment analysis (Reference 3) indicates the NPSH available while the RCIC pump is drawing on the torus is sufficient and that RCI C can provide adequate make up. The use of the torus at elevated temperatures will be c onsidered based on BWROG findings. Figure 1 provides a simplified FLEX flow diagram.

Cold Shutdown and Refueling The overall strategy for the Maintain Core Cooling function during Cold Shutdown and Refueling (Modes 4 and 5, respectively) are generally simi lar to those for Power Operation, Startup, and Hot Shutdown.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 14 of 55 Maintain Core Cooling If an ELAP occurs during Cold Shutdown, water in the vessel will heat up. When the temperature reaches 212 °F (i.e., Hot Shutdown conditions), the vessel will begin to pressurize.

During the pressure rise RCIC can be returned to service with suction from the CST to provide injection flow. When pressure rises to the SRV se tpoints, then reactor pressure vessel pressure will be controlled by SRVs. During Refueling, many variables exist which impact th e ability to cool the co re. In the event of an ELAP during Refueling, there are no installed plant systems designed to cool the core available. To accommodate the activities of vessel disassembly and refueling, water levels in the reactor vessel and the reactor cavity are often changed. The most limiting condition is the case in which the reactor head is removed and water level in the vessel is at or below the reactor vessel flange. If a BDBEE (i.e., ELAP/LUHS) were to occur during this condition, then (depending on the time after shutdown) boiling in the core may occur quite rapidly (possibly within an hour). In such a situation, JAF does have a seismic-qualified diesel-driven fire pump (76P-1) available. In addition, there are staged hoses (4"-diameter) that can be used to esta blish a cross-connection between the fire protection system and the RHR Service Water system; there are also installed cross-connections from there to the RHR system.

Thus a flow path can be established to provide make-up flow to the reactor pressure vessel. The fire pump draws suction on the intake bay of the Ultimate Heat Sink (Lake Ontario.) Deployment and implementation of response strategies during Mode 5 must commence immediately after the time of the event. A rapid response during a Mode 5 scenario is plausible based on the availability of additional resources on-site to support the outage activities. Guidance will be provided to ensure that sufficient area is available for deployment and that haul paths remain accessible without interference from outage equipment during refueling outages.

Provide a general description of the coping strate gies using on-site portable equipment including modifications that are proposed to maintain core cooling. Identify methods (RCIC/HPCI/IC) and strategy(ies) utilized to achieve this coping time.

Primary Strategy During Phase 2, as in Phase 1, reactor core cooling is maintained using RCIC in automatic mode (i.e., with operators controlling the RCIC flow controller) with sucti on from the CST or the torus. Based on Reference 3, the initial CST volume, in conjunction with the volume of water in the torus used during hours 2 through 5 of the event, will enable RCIC to provide make-up for at least 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months without replenishment. Prior to the depletion of the CST, JAF will establish the flow path from the seismically-qualified diesel-driven fire pump 76P-1 to provide make up to the reactor pressure vessel. A pre-staged hose will be used to connect the fire protection system to the RHR Service Water system at valve

10RHR-432 (see Figure 1). RHR Service Water system is then connected to the RHR system through the cross-connect fl ow path by opening valves 10MOV-148A and 10MOV-149A. The reactor pressure vessel is then de-pressurized to less than 50 psig. The LPCI injection valves, 10MOV-27A and 10MOV-25A are then opened to provide the makeup flow into the reactor pressure vessel. (References 1, 2) This is also the alternate strategy described below in the event the RCIC system is unavailable.

During Phase 2, reactor pressure is controlled by operation of SRVs as described in Phase 1.

The 125 VDC batteries are available for up to 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months without recharging (Reference 4). A modification will provide new connection points for a portable diesel generator unit to re-power the Battery Chargers 71BC-1A (or 71BC-1B), whic h charge the batteries and supply DC loads. The FLEX 600 VAC, 200 kW DG will be connected at approximately 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and is sized to power the battery charger and fans (about 90 kw).

Figure 1 provides a simplified FLEX flow diagram and Figure 2 is a simplified FLEX one-line diagram. Alternate Strategy Providing defense-in-depth for RCIC, the seismically-qualified diesel-driven fire pump (76P-1) can be used to provide makeup to the reactor pres sure vessel as described for the Phase 1, Cold Shutdown and Refueling response and also above for the primary strategy as the CST is depleted. This alternate strategy would be implemented as described above.

As a backup to this alternate strategy, a portable FLEX pump can be used to draw water from the intake bay and pump it through a temporary hose connected to the RHR Service Water (RHRSW) system (also at valve 10RHR-432). The FLEX pum p would be lowered through a hatch at El 255' of the Screenwell and pump into a temporary hose to the RHRSW conne ction (at valve 10RHR-432) to provide make up to the reactor pressure vessel through the same flow path described above. This portable FLEX pump can also be used to make up to the CST, providing additional defense in depth for this strategy. Replenishment of the CST will be accomplished either through a new underground pipe or above ground through approximately 600' of hose. This same pump is James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 18 of 55 Maintain Core Cooling BWR Portable Equipment Phase 2:

also used to provide the make up to the spent fuel pool, which will be discussed below in the Maintain Spent Fuel Pool Cooling function. As an alternate strategy to that of powering the battery chargers from their Class 1E 600 VAC electrical buses, connections will be provided to enable power to be provided directly to the battery chargers. This will enable the use of a 90 kw FLEX 600 VAC DG to power the battery charger. Permanently installed cables will be run to facilitate the use of this alternative power arrangement (Reference 5).

For Cold Shutdown and Refueling strategies s ee the discussion in the Phase 1 section above.

Diesel fuel to support operation of the portable Phase 2 FLEX equipment for at least 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months will be stored with the FLEX equipment. Additiona l diesel fuel is availa ble in the underground EDG fuel storage tanks. The Divisi on I & II EDG fuel oil storage tanks contain more than 128,000 gallons of fuel oil (Reference 6, Table B3.8.3-1). The underground EDG fuel oil storage tanks contain sufficient fuel oil to suppor t all Phase 2 strategies. If the normal procedure for transferring fuel from the underground storage tanks is not po ssible, the fuel oil can be obtained from the underground storage tanks using a manual, air, or battery operated pump to pump the fuel into a transfer tank.

Provide a general description of the coping strategies using phase 3 equipment incl uding modifications that are proposed to maintain core cooling. Identify methods (RCIC/HPCI/IC) and strategy(ies) utilized to achieve this coping time.

Primary Strategy For Phase 3, the reactor core cooling strategy is to place one loop of RHR into the Shutdown Cooling mode. This will be accomplished by powering up a Division I (10P-3A or -3B) or II (10P-3C or -3D) RHR pump from the Class 1E emergency 10500 or 10600 bus, respectively, utilizing a 4160 VAC FLEX portable diesel generator supplied by the RRC. Re-powering either bus can power an RHR pump that can provide fl ow to either RHR heat exchanger (HX). A modification will be implemented to provide a cross-connection between the fire protection system and one train of the RHRSW system. The seismica lly qualified diesel-driven fire pump (76P-1) will be used to provide lake water to the tube side of the appropriate RHR HXs (i.e., either 10E-2A or -2B). The diesel-driven fire pump provides 2500 gallons per minute at a nominal discharge pressure of 125 psig (Reference 2).

The 4160 VAC RRC FLEX diesel ge nerator will be capable of carrying approximately 2000 kW load which is sufficient to carry all of th e loads on the Class 1E 4160 VAC bus 10500 or 10600 necessary to support the Phase 3 FLEX strategies which includes an RHR pump and its support equipment (i.e., MOVs, room coolers, etc.) (about 1600 kw). In order to prevent pipe damage due to water hammer, the 'keep full' pumps will be repowered to allow proper venting prior to RHR shutdown cooling operation. The primary strategy is to re-power Class 1E bus 10500 feeding either the RHR A or B pump, each capable of using its respective HX. An alternative strategy re-powers Class 1E bus 10600 feeding either the RHR C or D pump, each capable of using its respective HX. The selection of which pump would be used will depend on which RHRSW train is selected for the fire protection-to-RHRSW cross-conne ct modification. Figure 1 provides a simplified FLEX flow diagram and Figure 2 is a simplified FLEX one-line diagram. Alternative Strategy An alternate means of providing power to the RHR pumps for SDC operation is to run cable from the 4160 VAC RRC FLEX DG directly to the component by connectin g either at the switchgear end of the component's power cable or locally at the pump end of the power cable.

Notes: None James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 24 of 55 Maintain Containment Determine Baseline coping capability with installed coping modifications (i.e., modifications installed to increase initial coping time) not including FLEX modifications, utilizing methods described in Table 3-1 of NEI 12-06: Containment Venting or Alternate Heat Removal Hydrogen Igniters (Mark III containments only)

BWR Installed Equipment Phase 1:

Provide a general description of the coping strategies using installed equipment including modifications that are proposed to maintain containment integrity. Identify methods (containment vent or alternative /

Hydrogen Igniters) and strategy(ies) utilized to achieve this coping time. During Phase 1, containment integrity is maintained using the normal installe d design features of the containment such as the containment isolation valves and the RHVS. In accordance with NEI 12-06 (Reference 2), the containment is assumed to be isolated following the event. As the torus heats up and the water begins to boil, the containment will begin to heat up and pressurize.

Additionally, the torus level rises due to the transfer of inventory from the CST to the torus (via RCIC and SRVs). According to the event response analysis (Reference 3), the limiting containment parameter will be the torus design pressure. The rise in drywell pressure can be reversed before the design pressure limit is reached. This is accomplished by venting the containment. In this case, the RHVS as implemented per EA-12-050, Reliable Hardened Containment Vents (Reference 4), is used with control from the relay room. The containment design pressure is 56 psig (Reference 1, JAF FSAR Section 5.2). The event response analysis (Reference 3) assumed that the containment is ve nted at about 23 hours2.662037e-4 days 0.00639 hours 3.80291e-5 weeks 8.7515e-6 months into the event. This timing was derived from the timing of the containment response of the drywell pressure approaching the design pressure; this venting assumption was made to ensure that the containment pressure limit is not challenged. The torus temperature is also a limiting factor for implementation of the ELAP strategy (Reference 3). The torus is utilized as a suction source for the RCIC system that serves as the primary strategy for the core cooling function, as discus sed in Phase 1 Core Coo ling section above. The event response analysis has assumed the RCIC suc tion will be swapped from the torus to the CST when the torus temperature reaches 170 °F. This occurs at about 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months into the event. The primary strategy during Phase 1 of the BD BEE response relies solely on the use of permanently installed plant equipment/features. Th e event response analysis indicates that this strategy supports containment integrity through all Phases of the event. An alternative strategy for containment during Phase 1 is not provided, because containment integrity is maintained using only qualified installed plant design features.

Provide a general description of the coping strategies using installed equipment including modifications that are proposed to maintain spent fuel pool cooling. Identify methods (makeup with portable injection source) and strategy(ies) utilized to achieve this coping time.

There are no Phase 1 actions required for more th an 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months . Installed equipment available for spent fuel pool make-up is described below.

Fuel in the SFP is cooled by the existing water inventory requirements (i.e., at least 21'-7" of water normally maintained over top of fuel (Reference 1, Specification 3.7.7)) . The normal SFP water level at the ev ent initiation provides for at least 21 feet, 7 inches (Reference 1, Specification 3.7.7) of water invent ory above the top of the stored spent fuel. Using the design basis maximum heat load, the SFP water inventory will heat up from an initial 114°F to 212°F during the first 37.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months (Reference 2). That ca lculation also predicts that there would be approximately 305 hours0.00353 days 0.0847 hours 5.042989e-4 weeks 1.160525e-4 months before any uncovering of the fuel would occu

r. These values consider the decay heat from a fresh reload batch in the pool upon startup from a 30-day refueling outage. SFP level monitoring is accomplished using the instrumentation installed per NRC Order EA 051. Cold Shutdown and Refueling During Mode 4 and prior to the fuel shuffle, the time to boil is expected to be even longer as the outage is getting underway before the recent spent fuel has been added to the pool. During Mode 5, the maximum heat load situation in the pool could occur if a full-core was off-loaded into the pool. The heat load calculation (Reference 2) indicates the time to boil in this scenario could be as little as 8.1 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . Even with this time to boil the fuel is expected to be protected for a substantial amount of time: the tim e to uncover the fuel is 65 hours7.523148e-4 days 0.0181 hours 1.074735e-4 weeks 2.47325e-5 months and the peak required make up rate is approximately 60 gpm. This indicates there is time to deploy the planned FLEX equipment. That this scenario occurs during an outage at the plant also makes available more staffing resources (i.e., in creased staffing is planned duri ng outages to support the outage initiatives.) The deployment of portable resources is discussed in the Phase 2 section below.

During Mode 4 and following the fuel shuffle, the time to boil is expected to be somewhat longer than that described for the worst-case Mode 5 condition. A similar respon se strategy is used.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 32 of 55 Maintain Spent Fuel Pool Cooling BWR Portable Equipment Phase 2: Provide a general description of the coping strate gies using on-site portable equipment including modifications that are proposed to maintain spent fuel pool cooling. Identify methods (makeup with portable injection source) and strategy(ies) utilized to achieve this coping time.

As noted in the Maintain Spent Fuel Pool Cooling Strategy for Phase 1, the spent fuel pool time to boil on a loss of cooling is approximately 37 hours4.282407e-4 days 0.0103 hours 6.117725e-5 weeks 1.40785e-5 months . The normal SFP water level at the event initiation is at least 21 feet -

7 inches (Reference 2, Sp ecification 3.7.7) over the top of the stored spent fuel. Using the design basis maximum heat load, the SFP water inventory will heat up from 114 °F to 212

°F in approximately 37 hours4.282407e-4 days 0.0103 hours 6.117725e-5 weeks 1.40785e-5 months (in Modes 1, 2, 3, or 4) or in approximately 8.1 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months in Mode 5 full core off-load scenario. Note that JAF does not typically plan their outage to include a full-core off-load. In addition to having plenty of time for any response actions, JAF also has permanently installed equipment that can be used to provide make up to the SFP. A flow path through the cross-connection between the fire protection system piping and the Train A of the RHRSW system can be established using a currently staged hose. Flow is then directed through the RHRSW-to-RHR cross-connect and into the RHR system piping. From there, a flow path using the SFP cooling assist piping can be establishe d, as described in Method 1 below.

This piping discharges flow through diffusers near the floor in the spent fuel pool. (References 3, 4, 5). Thus, the transition from Phase 1 to Phase 2 for SFP cooling function will occur at approximately 37 hours4.282407e-4 days 0.0103 hours 6.117725e-5 weeks 1.40785e-5 months in the normal condition in which fuel has been transferred to the pool after a refueling. Spent fuel pool makeup connections can also be established using portable FLEX equipment. The FLEX pump used to provide the SFP makeup function is the same FLEX pump described in the Core Cooling section to provide make up to the reactor pressure vessel and the CST. Portable equipment (i.e., provisions for makeup to the SFP) is expected to be in place for utilization at approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . The required makeup rate to maintain the fuel pool filled during this time is about 32 gpm in Modes 1 through 4 or about 65 gpm in Mode 5 (R eference 1). However maintaining the SFP full at all times during the ELAP event is not key requirement; rather the requirement is to maintain adequate level to protect the stored spent fuel and limit exposure to personnel onsite and offsite. Note that the time to boil is determined from the design basis decay heat load in the spent fuel pool. The design basis spent fuel pool heat load is the heat load 30 da ys following a refueling outage. Makeup to the SFP will be provided by one of three baseline capabilities.

Method 1 - Makeup via permanent piping The first method uses the existing fire pump (76P-1) aligned to the fire protection system header. A staged hose will be connected between the fire protection system and the RHRSW system through valve 10RHR-432 (Reference 4). The RHRSW system cross-connection to the RHR system is established through valves 10MOV-148A and 10MOV-149A (Reference 4). Flow can then be directed to the fuel pool cooling assi st piping (i.e., through 10M OV-20) (Reference 3) to the Spent Fuel Pool Cooling system (Reference 5). This provides make up flow to the SFP through seismically qualified piping to spargers located near the floor of the pool. The fire pump is capable of pumping 2500 gpm at 125 psig discha rge pressure; the requir ed flow rate for pool make up is less than 35 gpm (60 gpm duri ng a Mode 5 full-core off-load).

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 33 of 55 Maintain Spent Fuel Pool Cooling BWR Portable Equipment Phase 2:

Method 2 - Makeup via hose The second method to provide water to the SFP utilizes a portable FLEX pump. This pump will discharge into piping or hose and flow from th e Screenhouse around to near the track bay of the Reactor Building, and up to the operating floor of the Reactor Building. At that point, a hose long enough to reach the SFP is connected to allow filling of the SFP utilizing lake water (primary source) via FLEX pump. The flow requirement for this strategy is also between 35 and 60 gpm, which is easily supplied by the FLEX pump.

Method 3 - Makeup via spray Method 3 is a flow path ending in spray nozzles at the pool. NEI 12-06 guidance suggests a flow rate of consistent with 10 CFR 50.54(hh) (2). The third method of providing water to the SFP utilizes the FLEX pump and fl ow path described in Method 2. The hose connection at the operating floor, however, is connected to two monitor spray nozzles rather than simply pumping make up into the pool. Two 100 gpm nozzles, which satisfy the JAF 10CFR50.54(hh)(2) commitment, are currently stored in the Reactor Building. The FLEX pump will be capable of supplying 200 gpm to the refuel floor at a pr essure sufficient for the spray nozzles. Figure 1 provides a simplified FLEX flow diagram.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 37 of 55 Safety Functions Support Determine Baseline coping capability with installed coping modifications (i.e., modifications installed to increase initial coping time) not including FLEX modifications.

BWR Installed Equipment Phase 1 Provide a general description of the coping strate gies using installed equipment including station modifications that are proposed to maintain and/or support safety functions. Identify methods and strategy(ies) utilized to achieve coping times. Main Control Room Accessibility Under ELAP conditions with only simple mitigating actions taken, an analysis (Reference 1) projects the temperature in the control room will not exceed 105°F considering a loss of ventilation for three days. This is below the assumed maximum temperature for efficient human performance (110°F) as described in NUM ARC 87-00 (Reference 2). The calculation conservatively assumed that all of the equipment in the room is functioning; this is conservative compared to the BDBEE scenario in which some of that equipment will no longer be powered.

The calculation credited heat escaping through a damper in the floor of the kitchen. The Phase 1 FLEX strategy is to confirm the damper (70FD-8) (Reference 1) is open as well as to block open the entrance air lock when the MCR temperature reaches about 90 °F. Additionally, AOP-49 (Reference 5) requires opening al l MCR panel doors in the control room within 30 minutes of the beginning of an SBO to minimize heatup of the components contained in the MCR panels. RCIC Room Accessibility and Equipment Durability The RCIC room will have a large heat load under ELAP conditions, as the steam-driven RCIC pump is utilized during the event as the primary source of core cooling. The existing calculation, JAF-CALC-08-00007 (Reference 3), explores different cases of room heatup with a loss of all cooling considering the SBO scenario. It demonstrates that the RCIC room remains at acceptable levels for the four-hour SBO scenario. A preliminary evaluation of the room temperature response for the FLEX scenario indicates the room temperature will be elevated. Further evaluation of RCIC room temperature will be performed to confirm an acceptable environment is maintained. The strategy for the RCIC room is to ensure room doors are open or utilize portable fans to ventilate the area. The BWROG has evaluated operation of the RCIC system at extreme conditions (Reference 4).

One of the findings of the report was that if the EG-M control module is located in the RCIC room and the RCIC room temperature was projected to increase above 150 °F, the EG-M module could be impacted and consideration should be given to relocating the EG-M to an environmentally cooler location as an enhancement. The EG-M module is located in the RCIC pump area which has the potential of ex ceeding 150°F; additional analysis will be performed to determine peak RCIC room temperature during the event and, if necessary, the EG-M will be re-located to a cooler environment. The other focus of the BWROG eval uation (Reference 4) dealt with the effects of RCIC operation at pumped fluid temperature exceeding design rated temperature. The results and possible enhancements provided in the BWROG study will be considered in the coping strategy. For the purposes of NEI 12-06 it is not anticipated that continuous accessibility would be required James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 38 of 55 Safety Functions Support in the RCIC room. If personnel entry is required into the RCIC room, then supplemental ventilation and personnel protective measures (such as ic e vests) will be taken.

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 39 of 55 Safety Functions Support BWR Portable Equipment Phase 2 Provide a general description of the coping strategies using on-site portable equipment including station modifications that are proposed to maintain and/or support safety functions. Identify methods and strategy(ies) utilized to achieve coping times. Main Control Room As discussed above for the Phase 1 Safety Systems Support strategy, Refere nce 2 evaluated loss of Main Control Room (MCR) ventilation for three days. The analysis determined that the MCR would reach 104°F in 2.5 days. Equipment in the control room is designed to withstand a maximum MCR temperature of 104°F (Reference 2); 104°F MCR temperature would lead to approaching the 122°F temperature limit for equipm ent located inside MCR panels (Reference 4, Input 2). AOP-49 (Reference 5) requires opening all of the MCR panel doors within 30 minutes of the beginning of an SBO to minimize the temper ature difference between inside and outside the MCR panels. Portable fans powered from portable FLEX diesel generators will be provided to improve the heat removal from the MCR and maintain temperatures below 104°F for personnel accessibility and equipment availability during Phase 2. RCIC Room Accessibility and Equipment Durability Primary Strategy The primary strategy for maintaining the environment of the RCIC room during Phase 2 will use the same strategy as in the Phase 1 section above. Alternative Strategy It is not anticipated that accessibility of the RCIC room will be required, however, if personnel accessibility becomes necessary then supplemental methods of cooling or exhausting heat from the RCIC room will be established. Hydrogen gas is produced by the ba tteries during the charging pro cess that begins about eight hours into the BDBEE. A review of the battery room hydrogen generatio n rate calculation was performed. As demonstrated by th at calculation (Reference 1), the hydrogen generation rate during charging is such that the hydrogen concentration in the room does not reach 2% for more than 5 days. This is well into the Phase 3 deployment period. Thus, battery room ventilation is not a concern for the general Phase 2 strategy period of from 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months to 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . DC Equipment Rooms Ventilation The DC Equipment Rooms contain the battery chargers which are energized in Phase 2 to recharge the batteries. The method to ventilate the DC Equipment Rooms is to prop open doors and set up portable fans that will exhaust into an adjacent corridor that communicates with a roll up door to the outside. DC Equipment room actions are co vered under plant procedure (Reference 3).

James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 40 of 55 Safety Functions Support BWR Portable Equipment Phase 2 Spent Fuel Pool Area Per the NEI 12-06 guidance, a baseline capability for Spent Fuel Cooling is to provide a vent pathway for steam and condensate from the SFP.

Such a pathway can be established by opening the truck bay doors (at grade elevation) and opening the airlock on El. 369'-6" to the outside of the Reactor Building. The SBO/FLEX strategy is to establish this ventilation flow path early in the event response period (e.g., before the pool begins to boil, or prior to about 37 hours4.282407e-4 days 0.0103 hours 6.117725e-5 weeks 1.40785e-5 months .) Ventilation can be enhanced by re-powering a Standby Gas Treatment system (SGTS) fan. A modification to provide new connection points for a portable diesel generator unit to re-power a SGTS fan (e.g., 01-125FN-1A or -1B) will be considered. A FLEX 600 VAC, 200 kW DG will be connected as conditions warrant. A 200 kw 600VAC FLEX DG can power a SGTS fan and its valve. Other Areas Accessibility Other areas of the plant will require accessibility for operators or other station personnel during Phase 2 of a BDBEE. Generally, these areas are not expected to require mitigating actions or modifications for accessibility; however the areas will be evaluated to confirm accessibility.

Notes: None James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 43 of 55 Safety Functions Support BWR Portable Equipment Phase 3 Provide a general description of the coping strategies using phase 3 equipment incl uding modifications that are proposed to maintain and/or support safety functions. Identify methods and strategy(ies) utilized to achieve coping times. Main Control Room The primary and alternate strategies for cooling the MCR are the same in Phase 3 as for Phase 2.

However, the power for the MCR chillers and air-handling units may be powered from the 4160 VAC emergency bus if the bus is re-energized by the RRC FLEX 4160 VAC DG. RHR Room Accessibility As part of Phase 3 strategies, an RHR pump is placed into service in order to perform shutdown cooling. This results in heat addition to the RHR pump area due to heat generated by the RHR pump motor as well as heat dissipated from the associated piping. For long term RHR pump operation, the RHR pump area must be cooled to maintain area temperatures within acceptable ranges (limited by maximum allowable RHR pump motor requirements). Mitigating actions will therefore be employed; this can be accomplished by ensuring that cooling support is also powered when the RRC 4160VAC FLEX DG is connected to the Class 1E 4160 VAC bus to power the RHR pump. The room cooler can be energized and cooling water supplied via the connections provided between the fire protection system piping and ESW cooli ng water supply piping. An alternate means of cooling the RHR rooms if the RHR pump room coolers are not available is to use portable exhaust fans and hose trunks to exhaust hot RHR room air to outside the Reactor Building. Battery Room Ventilation As noted in the discussion of the Safety Systems Support Phase 2, the hydrogen gas evolves from the batteries as they are being charged. While the rate of hydrogen generation at JAF does not result in hydrogen concentrations of greater 2% for more than five days, the rooms will have to be ventilated during Phase 3. There are two strategies for venting the battery rooms. The primary strategy is to repower the existing battery room e xhaust fans. This could occur after the FLEX DG has been connected to power the Class 1E 600 V bus, but will more likely not be performed until the larger portable diesel generators are delivered from the RR C. The second option is to prop open doors and set up portable fans that will exhaust into an adjacent corridor that communicates with a roll up door to the outside. Battery and DC Equipment room actions are covered under plant procedure (Reference 1). DC Equipment Rooms Ventilation The method for cooling the DC Equipment Rooms is the same as described in the Phase 2 section of Safety Function Support.

Other Support Requirements James A FitzPatrick FLEX Integrated Plan, 2/28/2013 Page 44 of 55 Safety Functions Support BWR Portable Equipment Phase 3 Other areas of support required in Phase 3 are the same as described in the Phase 2 section of Safety Function Support.
