February 2013 FLEX Integrated Plan General Integrated Plan Elements (PWR & BWR)Determine Applicable Input the hazards applicable to the site; seismic, external flood, Extreme External Hazard high winds, snow, ice, cold, high temps.Ref: NEI 12-06 Section 5.0 -9.0 Describe how NEI 12-06 sections 5 -9 were applied and the JLD-ISG-2012-01 Section 1.0 basis for why the plant screened out for certain hazards.The applicable extreme external hazards for Brunswick Steam Electric Plant (BSEP) are seismic events; external flooding; storms with high winds, including hurricanes and tornadoes; ice; and extreme heat. The external hazards are detailed below.Seismic Hazard Assessment:

Per the FLEX guidance, seismic impact must be considered for all nuclear plant sites. Therefore, the BSEP site screens in for seismic hazards. As a result, the systems, structures, or components credited in the BSEP FLEX strategy (including portable and pre-staged FLEX equipment) will be assessed based on the current BSEP seismic licensing basis to ensure that the equipment, systems, structures, or components remain accessible and available after a seismic event and that the FLEX equipment does not become a target or source of a seismic interaction from other systems, structures or components.

The Design Basis Earthquake (DBE) at BSEP has a horizontal acceleration value of 0.16 g[Updated Final Safety Analysis Report (UFSAR) Section 2.5.2.5].

The Operating Basis Earthquake (OBE) at BSEP has a horizontal ground acceleration value of 0.08 g [UFSAR Section 2.5.2.6].Analysis has shown that soil liquefaction will not occur at the site under dynamic loadings of the DBE. [UFSAR Section 2.5.4.8] Therefore, soil liquefaction is screened out for the BSEP site.The protection of and deployment of FLEX equipment, procedural interfaces, and considerations in utilizing off-site resources during/after seismic events are being considered.

External Flood Hazard Assessment:

Information for this section is from UFSAR Section 2.0.At BSEP, the Probable Maximum Hurricane (PMH) defines the Probable Maximum Flood (PMF).The most severe flood conditions are associated with a PMH coinciding with peak local astronomical tides.The open coast stillwater surge is 22 feet Mean Sea Level (MSL). The surge stillwater level at the BSEP site is 22.0 feet MSL.The Cape Fear River transmits tidal flows very efficiently and, therefore, is expected to have a peak storm elevation of 23.3 feet MSL on shore. This peak tide will not reach the site, but will intercept natural ground about one fourth of a mile east of the site near River Road. Thus, no tide or wave action is expected to reach the plant from an overland direction.

In the intake canal, the still water level is expected to reach 22.0 feet MSL. The nominal plant grade of 20 feet MSL results in two feet of water depth surrounding the plant during maximum surge conditions.

Therefore, BSEP is not a dry site because site grade is below the maximum probable flood level and screens in for external flooding hazards. Safety-related structures are waterproofed to elevation 22 feet MSL.The wave action on structures on the ground will depend on the overland water depth caused by flooding.

This depth being 2.0 feet maximum, the highest wave that can be sustained will be 1.6 feet high. Larger waves over 1.6 feet coming from any overland direction will break when they Page 1 of 57 February 2013 FLEX Integrated Plan reach the 2-foot depth overland.

Wave run-up on a vertical wall associated with 1.6-foot waves is about 3.6 feet. Thus, the maximum instantaneous water elevation on any of these buildings is 25.6 feet MSL.Concerning the wave action on the Service Water Intake Structure, waves generated or propagated along the intake canal were conservatively estimated and reported as 3.0 feet high with a period of four seconds. The run-up due to these waves at the Intake Structure resulted in the maximum instantaneous water level of 28.3 feet MSL.The protection of and deployment of FLEX equipment, procedural interfaces, and considerations in utilizing off-site resources during/after flooding are being considered.

High Wind Hazard Assessment:

According to Figures 7-1 and 7-2 from Nuclear Energy Institute (NEI) 12-06 [Ref. 1], it was determined that BSEP has the potential to experience damaging winds caused by a hurricane up to 210 mph. Figure 7-2 indicates that BSEP, located at 33°57'30"N 78°00'30"W

[UFSAR Section 2.1.1.1], is within Tornado Region 1, where the recommended maximum tornado wind speed design is 200 mph. At BSEP, using NEI 12-06 guidance [Ref. 1], hurricane wind speeds exceed those of tornadoes.

High wind hazards are applicable to the BSEP site. Therefore, the BSEP site screens in to high wind hazards (hurricanes and tornadoes).

As a result, the systems, structures, or components credited in the BSEP FLEX strategy (including portable and pre-staged FLEX equipment) will be assessed based on the current BSEP licensing basis for high wind hazards to ensure that the equipment, systems, structures, or components remain accessible and available after a high wind event including interaction from other systems, structures or components during a high wind event. The protection of and deployment of FLEX equipment, procedural interfaces, and considerations in utilizing off-site resources during/after severe storms with high winds are being considered.

Snow, Ice and Extreme Cold Assessment:

Per NEI 12-06, BSEP is below the 35th parallel; therefore, the FLEX strategies are not required to consider the impedances caused by extreme snowfall with snow removal equipment.

Because the same basic trend applies to extreme low temperatures, per NEI 12-06, BSEP FLEX strategies are not required to address extreme low temperatures.

BSEP is a Level 4 region as defined by Figure 8-2 of NEI 12-06. Since the BSEP site is not in a Level 1 or Level 2 region, FLEX strategies must consider the impedances caused by ice storms.Therefore, the BSEP site screens in for impact of ice storms.The protection of and deployment of FLEX equipment, procedural interfaces, and considerations in utilizing off-site resources during/after conditions of ice are being considered.

Extreme High Temperature Hazard Assessment:

NEI 12-06, Section 9.2 states that virtually every state in the lower 48 contiguous United States has experienced temperatures in excess of 110°F and many in excess of 120'F. Per NEI FLEX Implementation Guide 12-06, "all sites will address high temperatures." Therefore, the BSEP site screens in for extreme high temperatures.

The protection of and deployment of FLEX equipment, procedural interfaces, and considerations in utilizing off-site resources during/after conditions of high temperatures are being considered.

Page 2 of 57 February 2013 FLEX Integrated Plan 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-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 on a schedule commensurate with other licensing bases changes.* Exceptions for the site security plan or other (license/site specific) requirements of 10 CFR may be required., Deployment resources are assumed 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 Specifications cannot be complied with during FLEX implementation.

The key assumptions associated with implementation of FLEX Strategies are provided below: 1. The general criteria and baseline assumptions, specified in NEI 12-06 Section 3.2.1, are applicable in establishing the baseline coping capability for BSEP.2. This plan defines strategies capable of mitigating a simultaneous loss of all alternating current (AC) power and loss of normal access to the ultimate heat sink, resulting from a beyond-design-basis event, by providing adequate capability to maintain or restore core cooling, containment, and spent fuel pool (SFP) cooling capabilities at all units on a site.Though specific strategies are being developed, due to the inability to anticipate all possible scenarios, the strategies are also diverse and flexible to encompass a wide range of possible conditions.

These pre-planned strategies developed to protect the public health and safety will be incorporated into the unit emergency operating procedures in accordance with established EOP change processes, and their impact to the design basis capabilities of the unit evaluated under 10 CFR 50.59. The plant Technical Specifications contain the limiting conditions for normal unit operations to ensure that design safety features are available to respond to a design basis accident and direct the required actions to be taken when the limiting conditions are not met. The result of the beyond-design-basis event may place the plant in a condition where it cannot comply with certain Technical Specifications and/or with its Security Plan, and, as such, may warrant invocation of 10 CFR 50.54(x) and/or 10 CFR 73.55(p).The following conditions exist: 1. All installed AC power supplies (emergency on-site and SBO Alternate AC power sources as defined by 10 CFR 50.2) will be considered not available and not imminently recoverable.

2. Direct Current (DC) power supplies are available.

3. AC and DC distribution is available.

4. Any future Station Blackout (SBO) or Extended Loss of Alternating Current Power (ELAP)Rule is assumed to be consistent with Order EA-12-049

[Ref. 2] and JLD-ISG-2012-01

[Ref. 5]. Different or additional requirements in the Rule may necessitate a change in the plans made in the BSEP response to the Order [Ref. 2].5. Plant initial response is the same as SBO.6. Entry to ELAP will be within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .Page 3 of 57 February 2013 FLEX Integrated Plan 7. Modular Accident Analysis Program (MAAP) analysis for decay heat is used to establish operator time and action.8. No single failure of a system, structure, and component (SSC) is assumed.9. SSCs will be considered seismically robust if seismic requirements are imposed by licensing requirements.

10. Where non-safety, non-seismically designed, permanently installed equipment is used for FLEX strategies, SSCs will be considered seismically robust if:* Seismic Qualification Utility Group (SQUG) methods are applied per the existing plant licensing basis.* Testing, analysis, or experienced-based methods are applied for the equipment class at design basis seismic levels.* Methodologies in EPRI 1019199, Experience Based Seismic Verification Guidelines for Piping and Tubing Systems, can be successfully applied relative to the Safe Shutdown Earthquake (SSE).* Other industry recognized codes such as AWWA D100 are applied to demonstrate functionality at SSE level ground motion.* High Confidence of a Low Probability of Failure (HCLPF) capacities are determined (e.g., EPRI NP-6041, Revision 1) conservative compared to the SSE.11. SSCs will be considered robust relative to tornado or hurricane winds if generally accepted standards and computer codes demonstrate that the SSC can perform its function using the maximum wind speeds outlined in NEI 12-06.12. The FLEX connections will either be qualified or in diverse locations.

13. Implementation strategies are assessed for hazards impact.14. Personnel access to, and qualification of, equipment that forms a part of the FLEX strategy assumes no core damage.15. Maximum environmental room temperatures for habitability or equipment availability is based on NUMARC 87-00 guidance if other design basis information or industry guidance is not available.

16. Although operation of portable equipment will not begin until Phase 2, pre-staging and alignment of portable equipment in Phase 1 using available on-site personnel will be credited.17. Per NEI 12-06 Section 12.1, on-site resources will be used to cope with the first two Phases of the event and for a minimum of the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of the event. Emergency Response Organization (ERO) personnel are assumed to begin arriving at 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and the site ERO will be fully staffed at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months after the event.18. Phase 3 resources (personnel and equipment) are assumed to start arriving within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months in accordance with the Regional Resource Center (RRC) playbook.

All resources from the RRC are assumed to be available within 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months .19. 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 program and addressed.

20. The 10 CFR 50.54(f) seismic and flood re-evaluations do not result in changes to the current desiqn basis. Additionally, it is assumed that the seismic re-evaluation does not Page 4 of 57 February 2013 FLEX Integrated Plan adversely impact the equipment that forms a part of the BSEP FLEX strategy.

Any changes to the seismic or flood design basis may require a change to the plans in the BSEP response to the Order [Ref. 2].Extent to which the Include a description of any alternatives to the guidance, and guidance, JLD-ISG-2012-01 provide a milestone schedule of planned action.and NEI 12-06, are being followed.

Transition to Phase 3 is expected to be completed approximately 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months after the BDBEE.Estimated deployment, connection, and action times were produced via table top exercise and have shown that the time-sensitive activities will be performed in sufficient time. A formal validation of timelines will be performed once the procedural guidance is developed and related staffing study is completed (Open Item 1). See the attached sequence of events timeline (Attachment 1A).Technical Basis Support Information

1. The sequence of events timeline was based on a coping time analysis using MAAP [Ref. 4].This analysis determined the key parametric values versus time.2. On behalf of the Boiling Water Reactor Owners Group (BWROG), GE-Hitachi (GEH)developed a document (NEDC-33771P, Revision 1 [Ref. 3]) to supplement the guidance in NEI 12-06 by providing additional BWR-specific information regarding the individual plant response to the ELAP and Loss of Normal Access to the Ultimate Heat Sink (LUHS) events.The document includes identification 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 methodology for BWRs' 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 BWR 4/Mark I containment analysis is applicable to the BSEP (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, containment integrity, and spent fuel pool cooling. The guidance provided in the document was utilized, as appropriate, to develop coping strategies and for prediction of the plant's response.

Specific hose routes have been identified for primary and alternate connection points (see Attachment 3 Sketches 1 through 3). Sketch 1 identifies hose routing for primary Reactor Pressure Vessel (RPV) and primary SFP injection.

Sketch 2 identifies hose routes for alternate RPV makeup. Sketch 3 identifies hose routes for alternate SFP makeup.Sketches 1 through 3 also identify the FLEX pump staging location.The identified paths and deployment areas will be accessible during all modes of operation.

BSEP will implement programmatic controls as defined below (Open Item 2). Procedures and guidelines will be reviewed and revised and/or generated as required to address additional programmatic controls as a result of FLEX requirements.

Equipment associated with these strategies will be procured as commercial equipment with design, storage, maintenance, testing, and configuration control in accordance with NEI 12-06 Section 11.1. Installed structures, systems and components pursuant to 10 CFR 50.63(a) will continue to meet augmented guidelines of RG 1.155, Station Blackout.

Depressurize RPV for injection with portable injection source" Sustained water source BWR Installed Equipment Phase 1: Level Control During an ELAP, with only DC power available, the main method of RPV level control is RCIC, with High Pressure Coolant Injection System (HPCI) as a backup. RCIC takes suction from either the CST or the Suppression Pool and pumps water into the RPV. The CST is the preferred source of feed to the RPV for makeup, since it is not subject to heat-up like the Suppression Pool. It also is the normally aligned suction source to RCIC and HPCI. However, if the CST is unavailable, RCIC takes suction from the Suppression Pool. [Ref. 6 and 13]As the Suppression Pool increases in temperature, RCIC will approach operating limits. In order to maintain RCIC availability, a clean water tank with availability to supply RCIC/HPCI will then provide a means of level control.Pressure Control Safety Relief Valves (SRVs) provide RPV pressure control during an ELAP. The steam from the RPV drives the HPCI/RCIC turbines, removing heat that would otherwise go directly to the Suppression Pool via the SRVs. The steam exhaust is then sent to the Suppression Pool to be quenched.Details: Provide a brief Confirm that procedure/guidance exists or will be developed to support description of implementation.

Operation of RCIC in Phase 2 requires adequate steam in the RPV for motive force and an available suction source within expected RCIC operating temperature limits. DC power enhances operating capabilities of RCIC, but is not required.As the Suppression Pool increases in temperature, RCIC will approach operating limits. As described in Phase 1, in order to maintain RCIC availability, a clean water tank with availability to supply RCIC will then provide a means of level control. If RCIC is unavailable, a portable FLEX pump will be used to provide makeup to the RPV from the CST (if available) or the clean water tank.After depressurizing the RPV, the primary means of providing level control is through portable FLEX pump.Pressure Control There are no changes in the methods for pressure control from Phase 1 to Phase 2.Details: Provide a brief Confirm that procedure/guidance exists or will be developed to description of support implementation.

After reactor scram, the RPV is depressurized using SRVs, per technical specifications of 1 00°F per hour. RCIC aligned to the Suppression Pool is used for RPV makeup. When the Suppression Pool reaches 200°F, RCIC is aligned to the clean water tank for the remainder of the event.RPV pressure is maintained using SRVs during the ELAP/FLEX event.

BWR Installed Equipment Phase I Equipment Power The Power Distribution System and/or the EDGs provide power to the 480 VAC Emergency Buses (E-Buses 5, 6, 7, and 8) at BSEP. These E-Buses provide power to critical loads for achieving and maintaining safe shutdown.

Upon an ELAP, these AC loads will be de-energized.

As a result, DC Power is required during ELAP with LUHS to power critical functions including (but not limited to)RCIC, HPCI, SRVs, vital instrumentation, emergency communications equipment, and essential lighting.

The battery chargers are de-energized during a BDBEE, leading to a loss of 125/250 VDC and associated functions in about two hours [Ref. 8].BSEP currently relies on the SBO procedure

[Ref. 8] to reduce non-essential DC loads as necessary to minimize battery discharge rate. In Phase 1, there is no method to restore DC power once the batteries are depleted; therefore, deep load-shedding strategies will extend the two hour coping time to approximately five hours. These deep loading shedding strategies do not have to be completed if Phase 2 power becomes available from at least one SAMA diesel generator.

Equipment Operating and Habitability Limits SBO heatup calculations performed in accordance with NUMARC 87-00 show that equipment operability will not be challenged during heatup in vital locations such as the Reactor Building Emergency Core Cooling (ECCS) Rooms. RCIC equipment room is expected to reach 145.3°F during an SBO event [Ref. 15]. The expected temperature in the HPCI room is 153.6 0 F, which is a backup to RCIC in a FLEX event. These temperatures are below the maximum normal temperatures of the associated rooms [Ref. 14].Operator manual action occurrence in areas where habitability is a concern will be minimized and a path for natural air circulation in the areas will be provided.Details: Provide a brief Confirm that procedure/guidance exists or will be developed to support description of implementation.

The SAMA diesel generators are able to power MCCs (1CA, 1CB, 2CA, and 2CB) which feed the 125/250 VDC battery chargers.

Each SAMA diesel generator will be capable of powering both unit Division II battery chargers, any required MOVs, Division II battery fans, and desired AC instrumentation as power is available.

An additional portable SAMA diesel generator is available to meet the N+1 equipment requirement.

This will be stored in the qualified structure with other FLEX equipment and deployed if necessary.

Equipment Operating and Habitability Limits See discussion in Safety Functions Support, BWR Portable Equipment Phase 1. In addition, operator manual action occurrence in areas where habitability is a concern will be minimized and a path for natural air circulation in the areas will be provided.

If necessary, high volume fans will force air through the areas to lower temperatures and improve habitability.

Details: Provide a brief Confirm that procedure/guidance exists or will be developed to description of support implementation.

Procedures I Strategies I Guidelines

Modify procedures such that operator manual actions in areas where habitability is a concern occur early in the FLEX timeline to the extent practical, while conditions are expected to be habitable.

Revise procedures to open Reactor Building doors to provide natural circulation path and utilize high volume fans if necessary to provide forced circulation throughout Reactor Buildings to improve habitability in these areas.* BSEP will utilize the industry developed guidance from the Owners' Groups, EPRI and NEI Task team to develop site specific procedures or guidelines to address the criteria in NEI 12-06.Page 31 of 57 February 2013 FLEX Integrated Plan Idniymodifications List modifications." Re-size the SAMA diesel generators to higher capacity.

Purchase a portable SAMA diesel generator to meet N+1 requirement of NEI 12-06. The N+1 SAMA diesel generator would be connected at an appropriate connection point. Add SAMA diesel generator connection points so that the SAMA diesel generator can tie into the Division II of the alternate unit. That is, the 2-SAMA-Diesel-1 diesel generator should add a tie into the 2CB bus and 2-SAMA-Diesel-2 diesel generator should add a tie into the 1 CB bus. The SAMA diesel generator switch should be modified to support providing charging loads to any of the three connected divisions.

See Attachment 3, Sketch 6 for more details.* Pre-stage the SAMA diesel generators in a qualified configuration.

Store the N+1 SAMA diesel generator in the FLEX Equipment Storage Building." Install modified breakers with quick connection points on MCCs 1 CA, 1 CB, 2CA, and 2CB to provide a secondary connection for repowering the MCCs.
