SUMMARY

a) Purpose In response to the NRC Request for Information regarding Near Term Task Force (NTTF)Recommendation 2.3, a flooding protection walkdown was conducted at Salem Generating Station (SGS) Units 1 and 2 to identify and address plant specific degraded, nonconforming, or unanalyzed conditions of the plant's flood protection features.

The flooding walkdowns at SGS were conducted between 9/10/2012 and 11/16/2012.

b) Scope The scope of the flooding walkdown was developed following a detailed review of all relevant licensing documents.

Certain safety-related structures, systems and components (SSCs) at SGS are situated below the design basis flood level. The station relies almost entirely on passive features incorporated in the design to keep water out of the plant. The flooding walkdown scope consisted of five main parts: " An outdoor walkdown was conducted to ensure no topography changes, added structures or security barriers affect site drainage as described in the Current Licensing Basis (CLB).* The Service Water Intake Structure (SWIS) above-grade and below grade passive flood protection structures (i.e., walls, floors, and ceilings and penetrations through those walls, floors and ceilings) were inspected." The powerblock above-grade and below-grade passive flood protection structures (i.e., walls, floors, and ceilings and penetrations through those walls, floors and ceilings) were inspected." The SWIS and powerblock active flood protection features such as sump pumps, associated check valves and flood protection doors were inspected." A review of procedures that implement active flood protection features was performed to confirm that the procedures are effective in ensuring their flood protection function.These areas are credited in the CLB to keep flood water from the bounding flooding event (a hurricane surge) out of the safety related buildings.

c) Methodology The methodology and acceptance criteria for the evaluation of flood protection features was developed based on NEI Report 12-07 [Rev O-A], "Guidelines for Performing Verification Walkdowns of Plant Flood Protection Features" [Ref. 2]. Visual inspections of walls, floors, ceilings and penetrations through the walls, floors, and ceilings were conducted to verify there are no observable structural deficiencies that may impact the structure's ability to remain watertight.

Visual inspection of active plant flood protection features was similarly performed to verify there are no observable structural defects or leakage. Implementing procedures for flood protection features were reviewed to verify, including the following:

that the procedures can be executed as specified/written, that credited time-dependent activities can be completed SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEGSL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 7 of 44 Project No. 12800-217 SGS Flood Walkdown Report in the time required, that resources required to complete the actions are available and are in good working order, and adequate staffing is available to implement the credited actions.d) Results and Conclusions Inspections of the SGS Flood Protection Features were performed in accordance with the NEI 12-07 Rev. OA [Ref. 2]. With the exception of potential deficiencies noted in Attachments A and D for SGS Units 1 and 2, respectively, the SGS Flood Protection Feature Inspections found that the SGS flood protection active and passive features, e.g., walls; floors, roofs, penetration seals, doors, sump pumps, check valves, etc., were confirmed to be installed per design, functional, in general good material condition, and appropriately controlled procedurally to ensure continued functionality.

Attachments A and D of this Report for SGS Units l and 2, respectively, identify and provide a summary of the potential deficiencies identified during the SGS Flood Protection Walkdowns that have not yet been dispositioned.

A small portion of the building surfaces (floors and walls) and some penetrations within the scope of the flood protection feature walkdown scope were deemed to be inaccessible and were not inspected.

Reasonable assurance that these portions of the buildings surfaces and the penetrations in these buildings are acceptable is based on the visual inspection of other similar walls, floors, and penetrations in similar elevations in these buildings that revealed no deficiencies or degradation that would prevent performance of flood protection features.

No visible signs of leakage were observed in the vicinity of those inaccessible flood protection features located below grade. Attachments B and E of this Report for SGS Unit 1 and 2, respectively, identify and provide a justification for the features that have been determined to be inaccessible.

Performance of the walkdowns provided confirmation that flood protection features are in place, are in good condition and will perform as credited in the current licensing basis (CLB).Minor issues were identified and entered into the PSEG corrective action program (CAP). No operability concerns were identified.

Attachments C and F of this Report for SGS Units 1 and 2, respectively, identify and provide a summary of the features that have been determined to have restricted access. Planning to perform the required flood protection feature walkdown / assessments is addressed within the PSEG CAP.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 8 of 44 Project No. 12800-217 SGS Flood Walkdown Report 2) PURPOSE a) Background In response to the nuclear fuel damage at the Fukushima-Dai-ichi power plant due to the March 11, 2011 earthquake and subsequent tsunami, the United States Nuclear Regulatory Commission (NRC) established the NTTF to conduct a systematic review of NRC processes and regulations, and to make recommendations to the Commission for its policy direction.

The NTTF reported a set of recommendations that were intended to clarify and strengthen the regulatory framework for protection against natural phenomena.

On March 12, 2012, the NRC issued an information request pursuant to Title 10 of the Code of Federal Regulations, Section 50.54(f) (10 CFR 50.54(f) or 50.54(f))

[Ref. 3] which included six (6) enclosures:

[NTTF] Recommendation 2.1: Seismic* [NTTF] Recommendation 2.1: Flooding* [NTTF] Recommendation 2.3: Seismic" [NTTF] Recommendation 2.3: Flooding* [NTTF] Recommendation 9.3: EP* Licensees and Holders of Construction Permits In Enclosure 4 of Ref. 3, the NRC requested that licensees perform flood protection walkdowns to identify and address plant-specific degraded, nonconforming, or unanalyzed conditions and cliff-edge effects (through the corrective action program) and verify the adequacy of monitoring and maintenance procedures.

1 SSCs important to safety are designed either in accordance with, or meet the intent of, Appendix A to 10 CFR Part 50, General Design Criteria (GDC) 2. GDC 2 states that SSCs important to safety at nuclear power plants must be designed to withstand the effects of natural phenomena, including floods, without loss of capability to perform their intended safety functions.

Flooding walkdowns identify/address plant-specific degraded, nonconforming, or unanalyzed conditions (through the corrective action program) and verify the adequacy of monitoring and maintenance procedures associated with flood protection and mitigation

' Cliff-edge effects were defined by the NTTF Report [Ref. 5], which noted that 'the safety consequences of a flooding event may increase sharply with a small increase in the flooding level'. While the NRC used the same term as the NTTF Report in the March 12 50.54(f)information request (Ref. 3), the information the NRC expects utilities to obtain during the Recommendation 2.3: Flooding Walkdowns is different.

To clarify, the NRC is now differentiating between cliff-edge effects (which are dealt with under Enclosure 2 of Ref. 3) and a new term, Available Physical Margin (APM). APM information will be collected during the walkdowns, but will not be reported in the response to Enclosure 4 of Ref. 3. The collected APM information will be available for use in developing the response to Enclosure 2 of Ref. 3.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEGSL Report No.: SL-2012-10795 Rev.

New flood hazard information will be considered in response to Enclosure 2 of Ref. 3.This Report provides the information requested in the March 12, 50.54(f) letter; specifically, the information listed under the 'Requested Information' section of Enclosure 4, paragraph 2 ('a'through 'h'). The 'Requested Information' section of Enclosure 4, paragraph 1 ('a' through 'j'), regarding flooding walkdown procedures, was addressed via the PSEG Nuclear (PSEG) June 07, 2012, acceptance

[Ref. 1] of the industry walkdown guidance [Ref. 2].b) Site Description The SGS is located in the southern region of the Delaware River Valley, which is defined as the area immediately adjacent to the Delaware River and extending from Trenton to Cape May Point, New Jersey on the eastern side, and from Morrisville, Pennsylvania, to Lewes, Delaware, on the western side. This region is characterized by extensive tidal marshlands and low-lying meadowlands.

More precisely, the SGS is located on the southern part of Artificial Island on the east bank of the Delaware River in Lower Alloways Creek Township, Salem County, New Jersey. While called Artificial Island, the site is actually connected to the mainland of New Jersey by a strip of tideland formed by hydraulic fill from dredging operations on the Delaware River by the U.S.Army Corps of Engineers.

The site is 15 miles south of the Delaware Memorial Bridge, 18 miles south of Wilmington, Delaware, 30 miles southwest of Philadelphia, Pennsylvania, and 7- 1/2 miles southwest of Salem, New Jersey, and approximately 50 river miles upstream of the mouth of Delaware Bay.The Delaware River Estuary system consists primarily of Delaware Bay, Delaware Estuary, and Delaware River. At the SGS site, tidal flows dominate over fresh water discharge.

The station is located on the east shore of the estuarian zone of the Delaware River -Delaware Bay system. Delaware River flow enters the head of Delaware Bay 2 miles downstream of the site. The largest tributaries of the Delaware River are the Schuylkill River in Pennsylvania; the Christina River in Delaware; the Assunpink, Crosswicks, Rancocas, and Salem Rivers; and Big Timbers, Hope, and Alloways Creeks in New Jersey.The head of the Delaware Estuary is at Trenton, New Jersey, about 83 miles upstream of the site. The Chesapeake and Delaware Canal, which connects the Delaware River with Chesapeake Bay, is located about 7 miles north of the Salem site.The water body to the west of the SGS is considered to be a tidally affected estuary by the U. S.Geologic Survey. As such, water levels are recorded by tidal gauges and no "flood record" is kept. The tidal flow in the site area is estimated to be more than an order of magnitude greater than the average fresh water flow in the site vicinity.

Thus, maximum and minimum water levels that may be of concern to plant safety were derived through considerations of coastal environmental conditions rather than riverine conditions.

The site area is generally flat with natural drainage flowing toward the Delaware River and into the marsh areas toward the north and east, previously having an average elevation of about 9 SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC S.

This was raised slightly in the plant area, to Elevation

+10.5 Mean Sea Level (MSL) or 99.5 Public Service Datum (PSD). Herein, Mean Sea Level (MSL) refers to the National Geodetic Vertical Datum (NGVD) datum, which at 0 feet is equal to the Public Service Electric and Gas Company datum (PSD) of + 89 feet. The SGS Turbine and Auxiliary Building ground floor levels are at Elevation 11.0 feet MSL (100 feet PSD). Herein, the MSL and MLW levels reported in the SGS UFSAR are converted to PSD for simplicity.

The main access to the plant is from a road constructed by PSEG. This road connects with Alloways Creek Neck Road about 2-1/2 miles east of the site. Access to the plant site and all activities thereon is under the control of PSEG.c) Requested Actions Per Enclosure 4 of Ref. 3, the NRC requests that each licensee confirm use of the industry-developed, NRC-endorsed, flood walkdown procedures or provide a description of plant-specific walkdown procedures.

In a letter dated June 07, 2012 [Ref. 1], PSEG confirmed that the flooding walkdown procedure

[Ref. 2], endorsed by the NRC on May 31, 2012, will be used as the basis for the flooding walkdowns.

Other NRC requested actions include: (1) Perform flood protection walkdowns using an NRC-endorsed walkdown methodology; (2) Identify and address plant-specific degraded, nonconforming, or unanalyzed conditions, as well as, cliff-edge effects through the corrective action program, and consider these findings in the Recommendation 2.1 hazard evaluations, as appropriate; (3) Identify any other actions taken or planned to further enhance the site flood protection; (4) Verify the adequacy of programs, monitoring and maintenance for protection features;and (5) Report to the NRC the results of the walkdowns and corrective actions taken or planned.Enclosure 4 of Ref. 3 also states, 'If any condition identified during the walkdown activities represents a degraded, nonconforming, or unanalyzed condition (i.e. noncompliance with the current licensing basis) for an SSC, describe actions that were taken or are planned to address the condition using the guidance in' Ref. 6, 'including entering the condition in the corrective action program. Reporting requirements pursuant to 10 CFR 50.72 should also be considered.'

d) Requested Information Per Enclosure 4 of Ref. 3, 1. The NRC requests that each licensee confirm that it will use the industry-developed, NRC endorsed, flooding walkdown procedures or provide a description of plant-specific walkdown procedures.

As indicated previously, PSEG's letter dated June 07, 2012[Ref. 1], confirmed that the flooding walkdown procedure

[Ref. 2], endorsed by the NRC on May 31, 2012, will be used as the basis for the flooding walkdowns.

The NRC endorsed NEI 12-07 on May 31, 2012 with amendments.

NEI 12-07 was updated to incorporate the amendments and re-issued on June 18, 2012. On June 7, 2012, PSEG issued a letter to the NRC [Ref. 1] stating that the endorsed flooding walkdown procedure

[Ref.2] will be used as the basis for the flooding walkdowns.

NEI 12-07 provides guidance on the following items: Definitions o Incorporated Barrier/Feature o Temporary Barrier/Feature o Exterior Barrier/Feature o Current Licensing Basis (CLB)o Design Bases o Inaccessible o Restricted Access o Deficiency o Flood Protection Features o Reasonable Simulation o Visual Inspection o Cliff-Edge Effects o Available Physical Margin o Variety Of Site Conditions o Flood Duration Scope o Basis for Establishing Walkdown Scope o Identify Flood Protection Features (Walkdown List)Methodology o Develop Walkdown Scope o Prepare Walkdown Packages o Walkdown Team Selection and Training o Perform Pre-Job Briefs o Inspection of Flood Protection and Mitigation Features" General" Incorporated or Exterior Passive Flood Protection Features" Incorporated or Exterior Active Flood Protection Features" Temporary Passive Flood Protection Features" Temporary Active Flood Protection Features" Procedure Walk-through and Reasonable Simulation o Review of The Maintenance and Monitoring of Flood Protection Features SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC SPSEG SL Report No.: SL-2012-10795 Rev.

Acceptance Criteria* Evaluation and Reporting Results of the Walkdown* Related Information Sources* Examples* Walkdown Record Form* Sample Training Content* Walkdown Report b) Application of NEI 12-07 PSEG's approach to the flooding walkdowns included three phases: Phase 1 -Preparation, Training, Data Gathering, and Scoping All walkdown team members completed the applicable NANTeL training and testing.Data gathering began with identification of station-specific licensing commitments and station design basis relative to external flooding events. This included review of the SGS UFSAR [Ref.13], identification of drawings showing flood protection features and review of station procedures and calculations relative external flooding events. A walkdown scope was developed to ensure station features credited as performing a flood protection function in the current licensing basis would be inspected.

Based on the walkdown scope, a walkdown list per building was prepared identifying the specific features to be inspected.

Walkdown packages per building room / floor were prepared for the specific features contained within those areas for use by the walkdown team in performing and documenting the walkdown.The scope developed for the walkdowns at SGS included the following: " The Service Water Intake Structure (SWIS) flood barrier surfaces, e.g., walls, floors, and ceilings.

The scope included the inspection of all exterior surface penetrations, as well as any active flood protection feature within the SWIS, e.g., sump pumps, check valves, doors and hatches.* Powerblock (SGS Auxiliary Building, Main Steam / Feedwater Penetration Areas, and Fuel Handling Building) flood barrier surfaces, e.g. walls, floors, and ceilings up to Elevation 130 feet PSD. The SGS Containment portion of the reactor building was not included in the inspection scope because its exterior walls and the floor are credited with leak tightness based on the periodic Integrated Leak Rate Testing." The potential for conduits from manholes or cable vaults to provide a path for ground water or rain water to enter safety related buildings was considered relative to the walkdown scope. For penetrations located within flood barrier surfaces, the plant information database SAP was reviewed to determine and include those SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC S jact 0 PSEGSL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 14 of 44 Project No. 12800-217 SGS Flood Walkdown Report penetrating commodities which originate within the flood barrier and terminate exterior to the flood barrier.An outdoor walkdown was conducted to ensure no topography changes, added structures or security barriers affected site drainage as described in the CLB.Phase 2 -Inspections and Reasonable Simulations Inspections of credited walkdown features were performed by the walkdown team following the guidance provided in NEI 12-07. Where potential deficiencies or other conditions were identified, these findings were documented and entered into the station CAP. The performance of a reasonable simulation was performed for the implementation procedure SC.OP-AB.ZZ-0001(Q), "Adverse Environmental Conditions"[Ref. 18]).Phase 3 -Final Reporting This Report has been developed to document the implementation of the program and to respond to the 50.54(f) information request regarding NTTF Recommendation 2.3: Flooding.c) Reasonable Simulations The purpose of reasonable simulations is to verify required flood protection procedures or activities can be executed as specified/written.

SGS relies on active incorporated watertight doors to function in a flooding event. To ensure that these active incorporated flood protection features are functional (closed / sealed) for an imminent flooding event, SGS Procedures:

OP-AA-108-111-1001 "Severe Weather and Natural Disaster Guidelines" [Ref. 17] and SC.OP-AB.ZZ-0001(Q) "Adverse Environmental Conditions" [Ref. 18] identify the performance of manual /operator actions intended to mitigate or protect against external flooding.Per NEI 12-07 [Ref. 2], reasonable simulation includes the following: " Verify that any credited time dependent activities can be completed in the time required.Time dependent activities include detection (some signal that the event will occur, has occurred, or is occurring), recognition (by someone who will notify the plant), communication (to the control room), and action (by plant staff)." Verify that specified equipment/tools are properly staged and in good working condition." Verify that connection/installation points are accessible." Verify that the execution of the activity will not be impeded by the event it is intended to mitigate or prevent. For example, movement of equipment across unpaved areas on the site could be impeded by soft soil conditions created by excessive water." Review the reliance on the station staff to execute required flood protection features.

If during the review several activities are identified to rely on station staff, then perform and document an evaluation of the aggregate effect on the station staff to demonstrate all actions can be completed as required.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0SL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 15 of 44 Project No. 12800-217 SGS Flood Walkdown Report" Verify that all resources needed to complete the actions will be available. (Note that staffing assumptions must be consistent with site access assumptions in emergency planning procedures.)" Show that the execution of the activity will not be impeded by other adverse conditions that could reasonably be expected to simultaneously occur (for example, winds, lightning, and extreme air temperatures).-" Personnel/departments that have responsibility for supporting or implementing the procedure should participate in the simulation effort." The simulation should demonstrate that the personnel assigned to the procedure do not have other duties that could keep them from completing their flood protection activities during an actual event. Actions that would be performed in parallel during an event should be simulated in parallel; not checked individually and the results combined."

No other possible sources of flooding exceed the hurricane flood level; hence, station design is predicated upon the worst possible Probable Maximum Hurricane (PMH) meteorological event.The maximum stillwater level associated with the PMH surge at the safety related structures and equipment is Elevation 113.8 feet PSD. The wave runup elevations on safety-related structures inside the sea wall are calculated to be a maximum of 120.4 feet PSD.The maximum wave run up elevation on the service water intake structure is calculated to be 127.3 feet PSD.Structure Max.

No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 17 of 44 Project No. 12800-217 SGS Flood Walkdown Report (1) Probable Maximum Flood For SGS, the probable maximum flood due to river flooding is bounded by the hurricane flood level and is not applicable, per SGS UFSAR Sections 2.4.2 and 2.4.5 [Ref. 13].(2) Probable Maximum Precipitation The maximum probable rainfall is of consideration only in design of yard drainage facilities and as a possible loading on critical structures, not as it may pertain to river flooding.

The Yard Drainage System is designed to pass the drainage associated with a rainfall rate of 4 inches per hour for a period of 20 minutes (based on 90 percent runoff from paved areas and 50 percent runoff from graded areas). This rainfall intensity has a return frequency of 15 years (see SGS UFSAR Figure 2.4-5 [Ref. 13]) and therefore, an unusually severe storm producing a rainfall rate in excess of 4 inches per hour for time periods of less than 20 minutes can be handled by the system.In the unlikely event that the Yard Drainage System was to be loaded beyond its capacity, the excess water would accumulate and run off (surface run off to the river) as the storm subsided.

All doors and penetrations in the Class I (seismic) buildings are watertight up to Elevation 115 feet (PSD). As a point of reference, the flood door threshold elevations are minimum 100 feet PSD, and the site grade adjacent to the Seismic Category I structures is 99.5 feet PSD. The interior drains in the Auxiliary and Fuel Handling Buildings are independently piped to the Liquid Waste Disposal System and are not connected to the Yard Drainage System.Roof drains are designed to dispose of a maximum rainfall rate of 4 inches per hour for a period of 20 minutes through the Yard Drainage System. Roof slabs are watertight to prevent building interiors from being damaged by severe rainstorms.

The slabs are designed to withstand a loading equivalent to a depth of water up to the full height of the building's parapet or roof curb. In the unlikely event that some of the roof drains become plugged, the backed up water will spill down the outside of the building.

Wall penetrations above Elevation 115 feet (PSD) on Class I (seismic) buildings are designed to prevent roof spillage or heavy rain from seeping inside the building.In the event the capacity of the Yard Drainage System were to be exceeded as a result of an unusually severe rainstorm, the excess water would accumulate in puddles in the vicinity of the catch basins and run off. This water would not enter any safety-related structure, since these structures are watertight up to Elevation 115 feet (PSD).Therefore, safety-related equipment would not be adversely affected as a result of a severe rainstorm.

(3) Potential Dam Failures For SGS, the potential dam failures are not applicable, see SGS UFSAR Sections 2.4.2 and 2.4.4 [Ref. 13].SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 PSLEA Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 18 of 44 Project No. 12800-217 SGS Flood Walkdown Report (4) Probable Maximum Surge and Seiche Flooding (Design Basis Flooding Hazard)The maximum stillwater elevation at the site is based on a combination of the storm surge and the crosswind setup or drawdown.

The Maximum Postulated Storm surge elevations have been calculated for the six fetches chosen and are presented in SGS UFSAR Table 2.4-1 [Ref. 13] with the computed crosswind setup and the maximum stillwater elevation at the site. The associated PMH was located so as to produce maximum waves. In the vicinity of the site, the PMH winds had a maximum sustained wind velocity of 85 miles per hour from the southeast.

With the surge level at 113.8 feet PSD, wave runup elevations on safety-related structures inside the sea wall were calculated to be a maximum of 120.4 feet PSD. Maximum wave run up elevation on the service water intake structure was calculated to be 127.3 feet PSD. The following sections summarize the SGS UFSAR discussion of the calculation of the PMH maximum storm surge, the maximum stillwater level, and maximum wave run up elevations.(a) Probable Maximum Winds and Associated Meteorological Parameters PMH storm surges have been calculated for the site using the bathystropic storm tide theory described by Marinos and Woodward (1968) (SGS UFSAR Section 2.4 Ref. 1) [Ref. 13]. The hurricane surge was computed at the mouth of Delaware Bay and routed up the bay in accordance with a method described by Bretschneider (1959) (SGS UFSAR Section 2.4 Ref. 2) [Ref. 13].Components of the stillwater level are: 1. the mean low water depth, 2. the astronomical tide, 3. the rise in water level resulting from the hurricane's atmospheric pressure reduction, 4. the wind stress component perpendicular to the bottom contours (onshore wind components), 5. the wind stress component parallel to the bottom contours which produces a longshore flow that is deflected to the right (in the northern hemisphere) by the Coriolis forces, and 6. the initial surge (a slow general rise in sea level existing before the actual hurricane winds arrive).The PMH is defined by the U. S. Department of Commerce Report HUR 7-97 (SGS UFSAR Section 2.4.14 Ref. 3) [Ref. 13] as: "A hypothetical hurricane having that combination of characteristics which will make it the most severe that can probably occur in the particular region involved.The hurricane should approach the point under study along a critical path and at an SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 PSLEA Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 19 of 44 Project No. 12800-217 SGS Flood Walkdown Report optimum rate of movement." Indices used to calculate maximum storm surge are taken in part from HUR 7-97 where values are grouped according to defined coastal zones.and by latitude within each zone.The track of the postulated hurricane is shown on SGS UFSAR Figure 2.4-6 [Ref. 13].Two different forward speeds of translation were used to determine the effect that the rate of forward movement of the hurricane would have on the surge elevation.

The PMH utilized in the analyses was a large radius, moderate forward speed hurricane which generated the maximum surge on the open coast. The quantitative meteorological parameters describing the PMH are: 1. Central Pressure Index: 27.09 inches Hg 2. Peripheral Pressure:

30.72 inches Hg 3. Radius of Maximum Winds: 39 nautical miles 4. Maximum Wind Speed: 132 miles per hour 5. Forward Speed: 27 knots A computer program was developed by Dames and Moore using previous work by the Galveston District Corps of Engineers.

Input data to the computer program describing the storm and the bathymetric conditions included the basic parameters of the hurricane, an initial surge of 1 foot, wind friction factor, bottom friction factor (0.008), wind speed at various radial distances and angles of wind direction relative to the translational velocity vector of the hurricane, bathymetric traverse data and astronomical tide (5.6 feet).Winds which approach the site from a direction off the axis of the bay produce a component which is perpendicular to the axis of the bay. This cross-wind component causes the water surface to be raised on the upwind side of the bay and depressed an equal amount on the downwind side of the bay.As the PMH is moved along its postulated track, wind speed and direction at the site change because of the effects of friction and filling over land and also because of the position of the storm center with respect to the site. The cross-wind effects were calculated for the six wind directions chosen for analysis.

The six wind directions or fetches radiate downbay from the site at 15-degree intervals from the east bank of Delaware Bay.The calculations consist of determining the corrected wind speed along the fetch, the cross-wind component of the wind speed, and the resulting cross-wind setup or drawdown.

A summary. of the calculations for each of the fetches is presented in SGS UFSAR Table 2.4-1 [Ref. 13].The wind speed was corrected to include the effect of the fetch distance from the storm center and also for friction and filling overland.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 NULEA Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 20 of 44 Project No. 12800-217 SGS Flood Walkdown Report The computed maximum surge elevation at the mouth of Delaware Bay was 21.9 feet above mean low water. This surge included the effects of the astronomical high spring tide.The maximum surge of 21.9 feet above mean low water at the mouth of Delaware Bay was routed to the site using the procedure of Bretschneider.

The model surge hydrographs for Delaware Bay computed by Bretschneider were then used to determine hurricane surge values at the Salem site as a function of time.The maximum stillwater elevation at the site is a combination of the storm surge and the crosswind setup or drawdown.

Storm surge elevations have been calculated for the six fetches chosen and are presented in SGS UFSAR Table 2.4-1[Ref. 13] with the computed crosswind setup and the maximum stillwater elevation at the site. The six wind fetches radiate downbay from the site at 15-degree intervals from the east bank of the Delaware Bay. Subsequently, site hydrologic design parameters were developed using a maximum surge elevation of 113.8 feet PSD, as recommended by the Nuclear Regulatory Commission consultants.(b) Wave Action The primary factors influencing the generation of waves will be the maximum wind speed over the water, the effective fetch length, and the average depth of water along the fetch. The values of these parameters used in the computations of wave heights and periods were determined for the fetches analyzed by: 1. Determining the location of the center of the storm required to produce winds along the fetch, 2. Calculating corrected wind speeds to account for friction and filling over the land and distance from the storm center to the fetch center, 3. Calculating the still water elevation at the center of the fetch due to storm surge at the time the storm center is located to produce the maximum wind speed along the pre-selected fetch, 4. Computing the average depth along the fetch.The basic assumptions used in the analyses were: 1. Storm generated waves from the open sea are dissipated at the mouth of Delaware Bay.2. Steady state waves are generated along each fetch (these waves are independent of time).3. Only the area northwest of Ben Davis Point generates significant wave energy at the site.The PMH was located so as to produce maximum waves. In the vicinity of the site, the PMH winds had a maximum sustained wind velocity of 85 miles per hour from SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC SL Report No.: SL-2012-10795 0 PSEG Rev.

With the surge level at 113.8 feet PSD, wave runup elevations on safety-related structures inside the sea wall were calculated to be a maximum of 120.4 feet PSD. Maximum wave run up elevation on the service water intake structure was calculated to be 127.3 feet PSD.(c) Resonance As a result of the nature of the estuary upon which the site is located, resonance was not a necessary consideration.(d) Runup The maximum wave runup elevation was calculated to be +120.4 feet PSD on critical structures inside the sea wall and 127.3 feet PSD on the service water intake structure.

The Sainflou method was used, assuming a minimum sea wall height of Elevation 108 feet PSD in the most critical area.(5) Probable Maximum Tsunami Flooding The occurrence of tsunamis is infrequent in the Atlantic Ocean. Other than the tidal fluctuation recorded on the New Jersey Coast during the Grand Banks earthquake of 1929, there has been no record of tsunamis on the northeastern United States coast.The earthquake of November 18, 1929, on the Grand Banks about 170 miles south of Newfoundland, resulted in a tsunami which struck the south end of Newfoundland about 750 miles northeast of the Massachusetts coast. The tsunami occurred at a time of abnormally high tide and resulted in some loss of life and destruction of property.

The effect of this tsunami was recorded on tide gages along the United States east coast, as far south as Charleston, South Carolina.

A tidal fluctuation of approximately nine-tenths of one foot was noted at Atlantic City, New Jersey and Ocean City, Maryland.The Lisbon earthquake of November 1, 1755, produced great waves, which contributed heavily to the destruction on the coast of Portugal.

These waves were noticeable in the West Indies. It had been reported that the Cape Ann, Massachusetts, earthquake of November 18, 1755, caused a tsunami in Saint Martin's Harbor in the West Indies;however, there is no record of a tsunami occurrence along the east coast of the United States at this time and it has since been determined that the Saint Martin's Harbor report actually refers to the tsunami caused by the Lisbon earthquake, which occurred within three weeks of the Cape Ann shock. Some tsunami activity has occasionally followed earthquakes in the Caribbean, but none of these was reported in the United States.There is no evidence of surface rupture in East Coast earthquakes and no history of significant tsunami activity in the region. Hence, we do not believe that the plant site would be subjected to any significant tsunami effect. The maximum expected tsunami would result in only minor wave action, and the maximum expected storm wave effect is the critical factor in design.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 Rev.

The containment is watertight and can withstand the static and dynamic loads associated with a storm producing stillwater level of 113.8 feet PSD and the corresponding wave runup to 120.4 feet PSD.The portion of the service water intake enclosing the pumps, motors, and vital switchgear is watertight up to Elevation 126.0 feet PSD with wave runup protection to Elevation 128.0 feet PSD. The service water intake can also withstand the static and dynamic effects of the storm. Each vertical, turbine type service water pump column bowl and suction bell is installed in an individual chamber which is open to the river. The chamber is isolated from the watertight compartments where the pump discharge heads and motors are located. The pump discharge heads are bolted down to pads to Elevation 92.5 feet PSD. The joint between the pump discharge head and the pad at Elevation 92.5 feet PSD is watertight to prevent leakage of water into the compartments.

Provisions have also been made to prevent leakage from the discharge head glands and leakoff connections into the watertight compartments.

A sump pump is provided in each compartment to remove any accumulated water in the event a minor leak should occur.The Auxiliary Building is watertight up to Elevation 115 feet PSD. All doors in the outer Auxiliary Building walls below Elevation 120.4 feet PSD are watertight.

All watertight doors and structural walls can withstand the static and dynamic effects associated with a storm that produces a stillwater level of Elevation 113.8 feet PSD with wave runup to Elevation 120.4 feet PSD. Conduit penetrations above Elevation 115 feet PSD and below Elevation 120.4 feet PSD are packed to eliminate gross inleakage during the storm.The main steam and feedwater pipe penetration area is watertight below Elevation 120.4 feet PSD.

Hydrostatic loadings from the hurricane condition were applied to the structures to check their stability.

The design and placement of the protective rockfill dike located along the portion of the Delaware estuary is such that it is subjected to maximum wind wave forces, thereby limiting the wave runup levels at the safety related structures and equipment to Elevation 120.4 feet PSD.The protective dikes are south of the power block between the Salem barge slip and the Salem circulating water intake structure, between the Salem circulating water and service water intake structures, and North of the Salem service water intake structu re.The shoreline protection and dike system is inspected by station operating personnel prior to storms and hurricanes and following the passage of such storms and hurricanes.

Additionally, a more complete annual inspection is conducted both by boat and from the dike itself. The station security forces also make regular patrols of these areas as part of their surveillance duties, and are instructed to report any abnormalities observed in the structure.

Waterproofing The underground portion of the containment structure is waterproofed in order to avoid seepage of ground water through cracks in the concrete.

The waterproofing consists of an impervious membrane which is placed under the mat and on the outside of the walls and extends vertically up to six (6) inches below yard grade. The Ethylene Propylene Diene Monomers (by Uniroyal, Inc.) membrane will not tear in handling or placing of backfill against it.(b) Incorporated or Exterior Active Flood Protection Features Watertight Doors In the event of rising water levels, all watertight doors will be closed to maintain watertight integrity.

SGS Technical Specifications specify the flood levels at which (1) watertight integrity will be established (at which time flood protection procedures will be initiated on a site-wide basis to protect the plant from flood waters) and (2) plant shutdown will be initiated.

All flood barrier doors in the Class I (seismic) buildings are watertight up to Elevation 115 feet (PSD).SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG NUCLEAR LLC Salem Generating Station Project No. 12800-217 SGS Flood Walkdown Report SL Report No.: SL-2012-10795 Rev.

No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 29 of 44 Project No. 12800-217 SGS Flood Walkdown Report ii) SGS Response (1) Floor Drains / Level Alarms No temporary or installed permanent plant warning system is credited with a flood protection function in the SGS external flooding licensing basis. During adverse weather conditions, Operators, per paragraph 3.9.2 of SC.OP-AB.ZZ-0001(Q) "Adverse Environmental Conditions" [Ref. 18], are instructed to monitor plant areas (rooms containing safety related equipment) for water ingress (seal or excessive crack leakage).Flood alarms installed and credited for internal flooding sources are available for detecting the accumulation of water resulting from ingress; however they are not credited for their flood protection function in the plants external flooding licensing basis. Such flooding alarms (sump level) are located in the Service Water Intake Structure bays as well in the Auxiliary Building.The design of the watertight pump compartments in the intake structure include a high sump level alarm in the event that a pipe rupture occurs which is larger than the capacity of the sump pump (125 gpm). The high sump level for the affected compartment is alarmed in the control room.Each residual heat removal pump room, the lowest point in the Auxiliary Building, contains two sump pumps, each adequate to provide the minimum capacity of 50 gpm (nominal 100 gpm each), which discharge to the Waste Disposal System. The design operating leakage rate of the RHR System is 50 gpm due to a pump seal failure. In the event of a major storm, which may be expected to cause flooding of the site, a number of temporary sump pumps are made available to remove any excess water which may enter the building.

The minimum total capacity of these temporary pumps is 2000 gpm and each pump is capable of pumping from the lowest building elevation to above Elevation 121 feet.In the Auxiliary Building the floor drains at Elevations 84 feet, 100 feet and 122 feet are piped to the waste holdup tanks. Elevation 64 foot drains are piped to the waste holdup tanks via the Auxiliary Building sump tanks and sump tank pumps. All drains below the elevation of the Auxiliary Building sump tank drain ultimately to the waste holdup tank. In addition, stairwells descending to elevation 55 feet PSD will also facilitate distribution of ground / flood water due to ingress to the RHR sumps.(2) Procedural Plant procedures provide direction for all plant personnel to report observed leakage in order to facilitate appropriate corrective action. Plant procedures (OP-AA-111-101-1001, "Use and Development of Operating Logs", S1(2).OP-DL.ZZ-0006(Q), "Primary Plant Log" and S1(2).OP-DL.ZZ-0005(Q), "Secondary Plant Log") provide direction for SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC a

Discuss how these systems and barriers were evaluated using the acceptance criteria developed as part of Requested Information Item 1.h.* The purpose of the 2.3 walkdowns is to verify the conformance with the CLB; the adequacy of the CLB will be addressed as part of the 2.1 flood reevaluations if an integrated assessment is required." The acceptance criteria for the walkdowns are described in section 6 of the guideline.

This approach is consistent with requested information item 1.h of the 50.54(f) letter.Discuss how the plant implemented this approach.* This discussion should include an evaluation of the overall effectiveness of the plant's flood protection features to perform their credited functions during a variety of site conditions (as defined previously), as determined by the results of the walkdowns (the features are available, functional, and implementable).

The CAP [corrective action program] process will determine which of the walkdown observations are deficiencies and what actions were taken or planned to address them. Questions such as the following should be evaluated for a variety of site conditions:

-Is the barrier system functional?

-Are operator actions feasible?* Describe how other existing plant equipment, structures, and procedures might mitigate the effects of an external flood under a variety of plant configurations.

Clearly describe what additional existing, if any, plant structures, systems, components, and procedures that are not part of the flooding CLB and that could be used to mitigate an external flood. Note that the Walkdown Report should include a description of existing plant capability, not an assessment of plant vulnerabilities to flooding that might exist under all susceptible plant configurations.

The assessment of plant vulnerabilities to all susceptible plant configurations will be completed, if applicable, as part of an Integrated Assessment performed in response to Enclosure 2 of Ref. 1.* Note: NUMARC 93-01, Rev 4A provides guidance on implementation of the maintenance rule. Section 11.3.4.2 of that document recommends an assessment of maintenance activities that expose SSCs to flood hazards in a manner that degrades their capability to perform key safety functions.

Credit for this activity could be included in this discussion.

No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 31 of 44 Project No. 12800-217 SGS Flood Walkdown Report ii) SGS Response (1) Purpose of the Walkdowns The purpose of the flood protection feature walkdown was to verify the conformance of exterior and incorporated flood protection features with the CLB.In addition to the visual component of the flood protection feature walkdown, a review of the preventative maintenance and surveillance programs was performed.

The purpose of the review was to validate that the credited features were contained in a program that would ensure their continued conformance with the CLB.The results of the flood protection feature walkdown investigation will be reviewed against the hazard reevaluation, as required, after the reassessment of flooding levels.If determined by the flood hazard reevaluation that an integrated assessment is warranted, a further evaluation of the adequacy of the CLB will be performed as result of the integrated assessment.

(2) Acceptance Criteria The acceptance criteria for visual inspections performed during the SGS flood protection feature walkdowns were taken from the general acceptance criteria provided within the NEI 12-07 Section 6 and Appendix A [Ref. 1] guidance.

These criteria were used, as applicable, for each type of SGS flood protection feature listed in Section 4) b) of this report. This approach is consistent with the Requested Information Item 1.h from Enclosure 4 of the 50.54(f) letter.(3) Evaluation of the Overall Effectiveness of the Plant's Flood Protection Features (a) Procedures The review of the flood protection features design and licensing documentation, and subsequent field inspection of the applicable physical flood protection features was implemented per the guidance provided within NEI 12-07. PSEG Nuclear has implemented ER-AA-310-1009 "Condition Monitoring of Structures" [Ref. 15] for condition monitoring of Maintenance Rule structures, such as with regard to the monitoring of flood control features:

concrete walls and slabs, water-control structure elements, penetration seals, etc. Specific instructions regarding the inspection of SGS Penetration seals are addressed in SC.FP-SV.FBR-0026(Q) "Flood and Fire Barrier Penetration Seal Inspection." Instruction regarding the inspection and maintenance of the SGS plant bulkhead doors is addressed in: SC.MD-PM.ZZ-0036(Q) "Watertight Door Inspection and Repair" [Ref. 19]. Therein, SC.MD-PM.ZZ-0036(Q) adequately identifies the Technical Specification related doors, requires a review to initiate a Plant Barrier Impairment (evaluation of taking the barrier out of service), and provides adequate notification

/ coordination with the Plant Operators.

SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0SL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 32 of 44 Project No. 12800-217 SGS Flood Walkdown Report SGS includes active flood protection features (Watertight Perimeter Doors) that require the implementation of procedures to initiate the performance of manual/operator actions (closing of the doors) in order for the feature to perform its intended flood protection function and the staging of temporary sump pumps in a flood protected area.A reasonable simulation was performed at SGS which confirmed that the actions described within the implementing procedure SC.OP-AB.ZZ-0001(Q), "Adverse Environmental Conditions" [Ref. 18] can be performed within the required period of time, and sufficient resources are allocated and staged to perform those actions.The SGS UFSAR Section 3.4.3.1 states: "In the event of a major storm, which may be expected to cause flooding of the site, a number of temporary sump pumps are available to remove any water which may enter the building.

The minimum total capacity of these temporary pumps is 2000 gpm and each pump is capable of pumping from the lowest building elevation to above Elevation 121 feet." OP-AA-108-111-1001

[Ref. 17] and SC.OP-AB.ZZ-0001(Q)

[Ref. 18] require confirmation that the pumps are available and to evaluate the need to relocate the pumps to a flood protected area in the event of a hurricane or flood. During preparations for Hurricane Sandy (October 28 through 30, 2012), availability of the temporary sump pumps was confirmed, thereby satisfying the UFSAR Section 3.4.3.1 commitment.

A notification has been issued to suggest enhancements to OP-AA-108-111-1001 (20584969) and SC.OP-AB.ZZ-0001 (20584978).

It is suggested that the procedures be supplemented with instructions as required to facilitate the implementation of the temporary sump pumps.(b) Accessibility The flood protection features that could be accessed were evaluated against the NEI 12-07 acceptance criteria.

Those features that were found to be restricted or partially accessible were entered into the PSEG CAP, i.e., a Notification was entered in SAP. Attachments C and F of this Report provide a list of the restricted-access features.

as well as the associated Notification number. The plan to perform the inspection of the restricted access flood protection features is provided in the PSEG CAP. Flood protection features classified as inaccessible are identified in Attachments B and E and are discussed in paragraph

ii) SGS Response Summary of Findings The plant flood protection features were found to be as described in the CLB (available, functional, and maintained), with the exception of issues that are evaluated as a potential deficiency.

These issues are listed and described in Attachments A and D of this report. In general, the inspection of the flood protection features, confirmed that the SGS credited flood protection features / barriers were found to be in place, in good condition, and capable of performing their design function as credited in the CLB. For the applicable flood protection features which were identified as potential deficiencies during the flood protection feature walkdowns, detailed observations, photographs, and qualitative dispositions were presented for consideration and input into the PSEG CAP process.Those flood protection features listed in Attachments B and E are "Inaccessible" in accordance with the guidelines provided within NEI 12-07 Rev. 0-A [Ref. 2]. A brief evaluation is provided below to provide reasonable assurance that the inaccessible flood protection feature can perform its design function.Those flood protection features listed In Attachments C and F have "Restricted Access" in accordance with the guidelines provided within NEI 12-07 Rev. 0-A. Access to perform the walkdown / inspection is currently prevented due to, typically, plant operating conditions preventing

/ limiting access or full or partial disassembly of plant structures is required to facilitate the inspection.

Flood protection features identified as being restricted access are entered in the PSEG CAP to schedule the performance of a future walkdown and evaluation.

A review of the potential deficiencies is performed, as part of the PSEG CAP process, to determine if the potential deficiency is a deficiency.

Potential deficiencies are identified and described in Attachments A and D of this Report for SGS Units 1 and 2, respectively.

Additional reviews to evaluate potential deficiencies and implement corrective actions to rectify the identified discrepancy are addressed within the PSEG CAP process.(2) Description of any Observations Reported in the CAP that were not Dispositioned Attachments A and D of this Report for SGS Units 1 and 2, respectively, include a listing and description of SGS flood protection feature walkdown observations (potential deficiencies) to be entered into the PSEG CAP.(3) Flood Protection Features that could not be Inspected (a) Restricted Access Features Those SGS flood protection features that were found to have restricted access are identified and described in Attachments C and F of this Report for SGS Units 1 and 2, respectively.

Additionally, Attachments C and F provide the justification for a delay in performing the flood protection feature walkdown / inspection and assessment.

The associated plan and schedule for performing the flood protection feature walkdown / inspection and assessment for those SGS flood protection features identified as having restricted access are addressed within the PSEG CAP. It is anticipated that no special procedures will be required to perform the flood protection feature walkdown inspection

/ assessment for those features considered SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEGSL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 37 of 44 Project No. 12800-217 SGS Flood Walkdown Report as having restricted access. Identification of the required instructions and criteria will be addressed within the PSEG CAP for the applicable flood protection feature.(b) Inaccessible Features Those SGS flood protection features that were found to be inaccessible are waterproofing, waterstops and items identified in Attachments B and E of this Report for SGS Units 1 and 2, respectively.

These inaccessible features are summarized below, (i) Waterproofing (Common to Unit 1 and Unit 2)The underground portion of the containment structure, auxiliary building and fuel handling buildings are waterproofed in order to avoid seepage of ground water through cracks in the concrete.

The waterproofing consists of an impervious membrane which is placed under the mat and on the outside of the walls. The membrane will not tear in handling or placing of backfill against it.To waterproof the subgrade exterior walls and foundations, a rubber waterproof membrane was installed under all foundations and was extended vertically up to 6 inches below yard grade. The horizontal waterproofing membrane was 1/16-inch thick Ethylene Propylene Diene Monomers (EPDM rubber). The waterproofing membrane used on vertical surfaces was 3/64-inch thick nylon reinforced Ethylene Propylene Diene Monomers (Nylon Fabric Inserted EPDM).Reason Inaccessible The waterproofing is located below grade and as such, ground adjacent to the plant structures would need to be extensively excavated to accommodate an inspection.

Functional Requirement Waterproofing and rubber waterstops prevent or limit water intrusion at the concrete construction joints and seismic gap joints so that safety-related equipment is not impacted by groundwater ingress.Basis for Reasonable Assurance that Feature is Available and Functional As the ground water level is only a few feet below site grade, the waterproofing is subjected to a continuous hydraulic gradient.

The Control Room Alarms are provided on sump level reaching pre-established sump level setpoints.

The ability of the existing waterproofing systems at SGS to perform their design basis function of protecting safety-related equipment from the effects of water ingress is confirmed by the fact that the plant drain system s are not challenged by the ingress of groundwater.

SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 PSLEA Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 38 of 44 Project No. 12800-217 SGS Flood Walkdown Report (i) Waterstops (common to Unit 1 and Unit 2)A waterstop is installed at the vertical and horizontal seismic joints between the reactor building to auxiliary building, reactor building to fuel handling building, and auxiliary building to fuel handling building to prevent groundwater and floodwaters from entering safety related structures through the seismic joints.The waterstop consists of a combination of lead coated copper metal flashing, a fabric reinforced silicone rubber gasket / seal, and stainless steel clamping bars secured with anchor bolts and/or keyed in to the concrete structure in reglets with a sealant as applicable.

Reason Inaccessible The waterstop construction is partially visible and a fire barrier would need to be partially disassembled in some areas to accommodate an inspection.

Functional Requirement Waterstops prevent or limit water intrusion past the seismic joints so that safety-related equipment is not impacted by the flood level.Basis for Reasonable Assurance that Feature is Available and Functional Control Room Alarms are provided on sump level reaching pre-established sump level setpoints.

The ability of the existing waterproofing systems at SGS to perform their design basis function of protecting safety-related equipment from the effects of water ingress is confirmed by the fact that the plant drain systems are not challenged by the ingress of groundwater.(ii) Elevator Shaft -Projection Bevel Plates (Common for Unit 1 and Unit 2)(Applicable to Features E-15333-EL 84, E-15333-EL 100, E-15333-EL 122)Two (2) auxiliary building elevator shaft walls have installed steel plate structures that preclude inspection of approximately 20% of one wall per elevator shaft. These plate structures are installed per Safety Code requirements to eliminate a personnel shear hazard at several elevations within the elevator shaft. The plates are installed in locations that are below grade as well locations that are above grade.Reason Inaccessible The plate structures obscure / prevent the observation of approximately 20% of the below grade wall surface. To inspect the wall behind the steel plate structures, the plates would have to be removed. The other sides of the elevator shaft walls are either below grade or are within the seismic gap between the auxiliary building and the containment building; so direct visual inspection is not feasible.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0SL Report No.: SL-2012-10795 PSLEA Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No.r39 of 44 Project No. 12800-217 SGS Flood Walkdown Report Functional Requirement The wall behind the steel plate structures is part of the auxiliary building flood boundary.

The auxiliary building flood boundary is designed to preclude ground/ flood water intrusion so that safety-related equipment is not impacted by the flood level.Basis for Reasonable Assurance that Feature is Available and Functional The remainder of the wall surfaces were inspected and found to be without visible defects, and no signs of previous water marks on the wall surfaces below the steel structures.

Control Room Alarms are provided on sump level reaching pre-established sump level setpoints.(iii) Pipe Chase.(Applicable to S-15206, W-25206)The exterior walls of the East Pipe Chase are below grade. The East Pipe Chase communicates with the pipe alley on Elevation 84 feet and with the RHR pump room sumps at Elevation 55 feet.Reason Inaccessible The east pipe shafts are accessible from the pipe alley at El. 84, but access is dose restricted.

Functional Requirement The exterior pipe chase walls are below grade and are part of the auxiliary building flood boundary.

The auxiliary building flood boundary is designed to preclude ground / flood water intrusion so that safety-related equipment is not affected.Basis for Reasonable Assurance that Feature is Available and Functional Drainage in the east Pipe Chase is designed for Moderate Energy Line (MEL)Breaks (internal flooding).

MEL Flooding in the RHR pump rooms can occur as a result of MEL fluid from breaks in the pipe alley on Elevation 84 feet which in turn communicates with Elevation 55 feet via a pipe chase. High RHR Sump sump level Alarms in the control room resulting from the ingress and accumulation of ground / external flood water will alert the control room operator to take compensatory action to limit the increase in sump level via the installation of temporary sump pumps.(iv) Penetration Seals Located Inside Concrete (Applicable to E-25504-001, E-25504-002, E-25504-249, E-25504-250)

Reason Inaccessible SGS FLOOD WALKOOWN REPORT 11-21-2012.000 0 PSEGSL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 40 of 44 Project No. 12800-217 SGS Flood Walkdown Report The penetration seals are physically located/ embedded in concrete.Functional Requirement Preclude water ingress of water into safety-related areas / structures.

Basis for Reasonable Assurance that Feature is Available and Functional The additional embedment of the penetrating commodities in concrete provides additional length that seeping ground water would have to travel to reach the inside of the room.Control Room Alarms are provided on sump level reaching pre-established sump level setpoints.(c) Inaccessible Feature Aggregate Effects The construction of the seismic category I structures includes several flood protection features configured in series that function to prevent / limit ingress of ground / flood water into the plant. In order for ground water to ingress into the plant several layers of the flood protection features would have to have been compromised

/ failed. Condition Monitoring of Structures via ER-AA-310-1009

[Ref.15] provides assurance that concrete structural elements (e.g., walls, slabs, etc.)remain capable of performing their design function.

As such, there is reasonable assurance that the failure of multiple in-series flood protection features is not likely.Control room alarms are provided on sump level reaching pre-established sump level setpoints.

As such, operator response would limit flood effects and prevent i mpact to safety-related equipment from groundwater ingress. In addition, the CLB identifies the availability of temporary sump pumps, having a total capacity of 2,000 gpm, for use in removing ground / flood water from areas containing safety related equipment.

g) Cliff Edge Effects i) NRC Request Document any cliff-edge effects identified and the associated basis. Indicate those that were entered into the corrective action program. Also include a detailed description of the actions taken or planned to address these effects.* Cliff edge effects and physical margins do not need to be reported to the NRC as part of the Walkdown Report. However, the Appendix B walkdown records, which include the collected APM information, need to be retained and available for NRC audits and inspections.

While the NRC used the sqme term as the NTTF Report [Ref. 5] in its 50.54(f) information request [Ref. 3] related to Flooding Recommendation 2.3, the information that the NRC expects utilities to obtain during the Recommendation 2.3 walkdowns is different.

To SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEGSL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 41 of 44 Project No. 12800-217 SGS Flood Walkdown Report clarify, the NRC is now differentiating between cliff-edge effects (which are dealt with in Recommendation 2.1) and a new term, Available Physical Margin (APM). APM information will be collected during the walkdowns, but will not be reported in the response to Ref. 3, Enclosure

4. The APMs determined by the Recommendation 2.3 walkdowns do not involve calculating the cliff-edge effects (i.e., the safety consequences).

During the Recommendation 2.1 integrated assessment, the cliff-edge effects and the associated safety risks will be determined using the APMs as well as other information, such as the specific SSCs that are subjected to flooding and the potential availability of other systems to mitigate the risk.Instead of submitting cliff-edge effects, this report documents that Available Physical Margins have been collected and documented in the Walkdown Record form [Ref. 2 Appendix B]. This information will be used in the flood hazard reevaluations performed in response to Item 2.1: Flooding in the 50.54(f) letter.ii) SGS Response (2) Cliff Edge Effects and Physical Margins As indicated in Section 3.12 of NEI 12-07, the NRC is no longer expecting the response to the Recommendation 2.3: Flooding Walkdowns of the 50.54(f) letter to include an evaluation of cliff-edge effects. The available physical margin (APM) has been estimated and documented, as applicable, in the walkdown record forms. The guidance provided in FAQ-006, Applicable Features for Quantifying APM, was also followed.

This information will be used in the flood hazard reevaluations performed in response to Item 2.1: Flooding in the 50.54(f) letter.h) Other Planned and/or Newly Installed Flood Protection Features or Measures i) NRC Request Describe any other planned or newly installed flood protection systems or flood mitigation measures including flood barriers that further enhance the flood protection.

Identify results and any subsequent actions taken in response to the peer review." Describe changes determined to be necessary by the flood walkdowns and whether they have been completed or their schedule for completion.

For the purposes of the flooding design basis walkdown verification, the peer review is the process described in section 7. The only actions and results that should be reported are those that resulted in a change to the walkdown process or methodology.

Corrections and resolution of differences resulting from the normal process of performer/ reviewer interaction are not reported.SGS FLOOD WALKDOWN REPORT 11-21-2012.D00 SPSEG SL Report No.: SL-2012-10795 Rev. No. 0 NUCLEAR LLC November 21, 2012 Salem Generating Station Page No. 42 of 44 Project No. 12800-217 SGS Flood Walkdown Report ii) SGS Response No new flood protection systems or flood mitigation measures including flood barriers were found necessary to enhance the SGS flood protection.

No changes were found necessary to flood protection or mitigation measures as a result of the SGS Flood Protection Feature Walkdowns.

Attachment H provides a review of changes to the walkdown process /methodology.

5) CONCLUSIONS Inspections of the SGS Flood Protection Features were performed in accordance with the NEI 12-07 Rev. OA [Ref. 2]. With the exceptions noted in Attachments A and D for SGS Units 1 and 2, respectively, as potential deficiencies, the SGS Flood Protection Feature Inspections found that the SGS flood protection active and passive features, e.g., walls, floors, roofs, penetration seals, doors, sump pumps, check valves, etc., were confirmed to be installed per design, functional, in good material condition, and appropriately controlled procedurally to ensure continued functionality.

A small portion of the building surfaces (floors and walls) and penetrations within the flood protection feature walkdown scope were deemed to be inaccessible and were not inspected.

Reasonable assurance that these portions of the buildings surfaces and the penetrations in these buildings are acceptable is based on the visual inspection of other similar surfaces and penetrations in similar elevations within these buildings, which revealed no potential deficiencies or degradation that would prevent performance of flood protection features.

No visible signs of leakage were observed in the vicinity of those inaccessible flood protection features located below grade.Performance of the walkdowns provided confirmation that flood protection features are in place, are in good condition and will perform as credited in the current licensing basis (CLB). Minor issues were identified under the PSEG CAP. No operability concerns were identified.

Attachments A and D of this Report for SGS Units 1 and 2, respectively, identify and provide a summary of the potential deficiencies that have not yet been dispositioned.

Attachments B and E of this Report for SGS Units 1 and 2, respectively, identify and provide a summary of the features that have been determined to be inaccessible.

Attachments C and F of this Report for SGS Units 1 and 2, respectively, identify and provide a summary of the features that have been determined to have restricted access. Planning to perform the required flood protection feature walkdown / assessments is addressed within the PSEG CAP.SGS FLOOD WALKDOWN REPORT 11-21-2012.DOC 0 PSEG SL Report No.: SL-2012-10795 Rev.
