2.0 Background

NextEra Energy Point Beach, LLC submitted License Amendment Request (LAR) 241 to the NRC pursuant to 10 CFR50.90.

The license amendment would revise the current licensing basis to implement the alternative source term (AST) through reanalysis of the radiological consequences of the Point Beach Nuclear Plant (PBNP) Final Safety Analysis Report, Chapter 14 Accidents.

During the review of LAR 241, the NRC staff expressed concern regarding the seismic adequacy of the Control Room Emergency Filtration System (CREFS) and Primary Auxiliary Building Ventilation System (VNPAB) credited in the PBNP AST analysis.

In response, PBNP committed (Reference

1) to evaluate the seismic adequacy of CREFS and VNPAB ventilation systems credited in the AST analyses.

The evaluation approach would be consistent with the approach used for the Edwin I. Hatch Nuclear Plant (Reference

9) to provide reasonable assurance that the credited post-accident ventilation systems would operate and retain pressure integrity during and following a seismic event.The PBNP seismic verification evaluation was conducted in accordance with the guidelines provided in the Generic Implementation Procedure (GIP) for Seismic Verification of Nuclear Plant Equipment (SQUG GIP) (Reference

8) for fans, motors and heat exchangers, and the December 2006 Electric Power Research Institute (EPRI)Final Report 1014608, "Seismic Evaluation Guidelines for HVAC Duct and Damper Systems, Revision to 1007896" for ducts, dampers and hangers (Reference 2). This seismic verification process was previously used at the Hatch Nuclear Plant (Reference

9) to provide reasonable assurance that a post LOCA ventilation system would retain pressure integrity during a seismic event. The NRC accepted and approved the Hatch seismic evaluation (see Reference 1 for discussion).

3.0 Methodology

and Scope The methodology in EPRI report "Seismic Evaluation Guidelines for HVAC Duct and Damper Systems, Revision to 1007896" was used to evaluate the seismic adequacy of the PBNP Control Room Emergency Filtration System (CREFS) and Primary Auxiliary Building Ventilation System (VNPAB). The screening guidelines are primarily based on seismic experience data that show that most types of HVAC duct and damper systems exhibit extremely good performance under strong-motion seismic loading, with the pressure boundary being retained in all but a handful of cases.The seismic verification evaluation for PBNP included the following key steps.1. Identified the HVAC systems that required evaluation by conducting interviews with station engineers and reviewing station drawings and design specifications.

The HVAC systems reviewed consisted of the Control Room Emergency Filtration System (CREFS) and Primary Auxiliary Building Ventilation System PBNP VNPAB and CREFS Seismic Verification Page 3 of 167 S&A Report No. 09Q0839-R-001 Revision 0 (VNPAB) credited in the PBNP AST analysis.

The components for these systems include:* Control Room HVAC ductwork, dampers, filters, and fans required for the proposed accident mode of operation (makeup and recirculation with filtration).

• Control Room Bathroom HVAC.* Control Room HVAC roof intake structure.

• Control Room HVAC control panel C-67 (located in the control room)." PAB exhaust ductwork, dampers, filters and fans located on or below Elevations 8' and 26' that provide exhaust for various ECCS equipment, components and sumps. This also includes ductwork in Pipeways 1, 3, and 4. (Note that there is no ductwork in Pipeway 2 associated with the subject scope of work).* PAB exhaust stack.* Confirmation that the power supplies for fans W-13 B! & B2 (Control Room Recirculation Fans), W-14 A & B (F-16 Control Room Charcoal Filter Fans), W21 A & B (PAB Exhaust Fans) and W30 A & B (F-23/F-29 PAB Exhaust Fans) were found to be seismically adequate in the original USI A-46 program for PBNP.2. Conducted an in-plant screening review of the subject systems for structural integrity, support review, seismic interaction, and pressure boundary integrity.

3. Selected bounding/sample configurations for limited analytical review (LAR)evaluations in accordance with Section 4 of Reference

2.4. Developed

this report and supporting calculations.

5. Submitted this report and sample calculations to an independent reviewer, Dr.Robert P. Kennedy for a Peer Review. Dr. Kennedy conducted the peer review for the previously cited Hatch duct evaluation.

It should be noted that the HVAC ductwork and plena for most of the CREFS are covered with a lightweight insulating material that obstructs viewing of some of the duct supports and duct stiffeners.

The material is in place not only for insulation but also to improve the leak tightness of the system. However, the recirculation duct for the CREFS is un-insulated which allowed the Seismic Review Team (SRT) to examine the construction, stiffener spacing, hanger spacing and type, and material condition of the ductwork.

This examination of the recirculation duct indicated the same type and quality of construction as that found for the VNPAB system; therefore the SRT considered it reasonable to adjudge that the number and location of CREFS stiffeners and duct supports within the insulated CREFS systems conform to the SMACNA code (Reference

4) and PBNP Ventilation System Design Specification (Reference

3) requirements and that the duct construction is adequate.

The dead load, seismic and pressure stresses in the CREFS ducts, duct stiffeners, and duct supports were evaluated based on this approach.

PBNP VNPAB and CREFS Seismic Verification Page 4 of 167 S&A Report No. 09Q0839-R-001 Revision 0 4.0 Applicability and Qualifications This section addresses the applicability of the materials and components used in the PBNP VNPAB and CREFS construction.

Temperature and seismic limits are also discussed along with the SRT and Independent Peer Reviewer qualifications.

4.1 Materials

and Components The PBNP CREFS and VNPAB HVAC systems consist of typical ducts, dampers, supports, registers, filters, louvers, and air diffusers that are discussed and addressed in Reference

2. These components were installed in accordance with the original Specification No. 6118-M-41 "Specification for Sheetmetal Ductwork Heating, Ventilating, and Air Conditioning Systems for the Point Beach Nuclear Plant" (Reference

3) which specified that the HVAC system be designed and installed in accordance with the requirements of the Sheet Metal and Air Conditioning Contractor's National Association, Inc (SMACNA) (Reference 4). As specified in Reference 3 the subject systems are constructed from galvanized sheet steel.4.2 Temperature The CREFS and VNPAB HVAC systems are low temperature systems with design temperatures well below the 4000 F limit discussed in Reference

2.4.3 Seismic

Motion The NRC Staff reviewed PBNP's USI A-46 implementation program and determined that the design basis ground spectra and resulting in-structure response spectra are considered conservative spectra (Reference 1 0).The same response spectra will be used for the seismic verification of the subject HVAC systems.The screening and seismic verification guidelines given in Reference 2 are applicable to any HVAC duct and damper system at any plant elevation where the plant free-field ground motion 5% damped seismic design spectrum does not exceed the Seismic Motion Bounding Spectrum of the Generic Implementation Procedure (GIP) for Seismic Verification of Nuclear Plant Equipment and the horizontal zero period acceleration (ZPA) of the in-structure spectra at the HVAC support anchorage does not exceed 2.0g.

PBNP VNPAB and CREFS Seismic Verification Page 5 of 167 S&A Report No. 09Q0839-R-001 Revision 0 The following table presents the results of the GIP bounding spectrum vs. PBNP free field comparison and the comparison of the PBNP horizontal ZPAs vs. the 2.Og requirements.

& Associates (S&A). Messer Djordjevic and Gazda are both experienced engineers who meet the requirements for Seismic Capability Engineers (SCE) described in the SQUG GIP (Reference 8). They are degreed engineers who have completed the SQUG developed training course on seismic and have performed SQUG walkdowns at numerous nuclear plants. Messer Djordjevic and Gazda each have over 30 years of nuclear plant experience and are licensed professional engineers.

Messer Djordjevic and Gazda have studied and are familiar with the content and intent of Reference 2, the HVAC duct and support design requirements of SMACNA and the seismic experience data for HVAC duct and damper systems.4.5 Peer Review Dr. Robert P. Kennedy was enlisted to perform the independent peer review of the seismic verification.

Dr. Kennedy is an industry seismic expert and performed an independent peer review of the seismic evaluation guidelines presented in Reference

2.

PBNP VNPAB and CREFS Seismic Verification Page 6 of 167 S&A Report No. 09Q0839-R-001 Revision 0 Dr. Kennedy served as the chairman of the independent Senior Seismic Review and Advisory Panel, which provided considerable technical review and advice during the development of the SQUG GIP approach for evaluating the seismic adequacy of 20 classes of equipment plus Cable and Conduit Raceway Systems and their supports.The independent review consisted of a site visit and a review of the supporting calculations, Screening and Evaluation Worksheets (SEWS) and Limited Analytical Reviews (LARs). The results of the Dr. Kennedy's independent review are provided in Attachment 12.6 and discussed in Section 10.5.0 In-Plant Screening Walkdown The initial in-plant screening walkdowns were conducted over 5 days from August 31, 2009 through September 4, 2009 by the SRT. Follow-up walkdowns were performed on September 24 and 30, 2009. Prior to the walkdowns the SRT conducted interviews with plant staff to clearly identify the HVAC systems requiring the seismic verification.

Plant documents were collected and reviewed to familiarize the SRT with the subject HVAC systems.The following table provides a list of the PBNP design drawings that show the VNPAB and CREFS HVAC systems.HVAC Drwg.

Vent Stack, Elevations, Sections, Details The original Point Beach Ventilation System Design Specification No. 6118-M-41 (Reference

3) was also reviewed.

Key information given in the specification is provided below.1. The work, equipment and materials shall conform to the requirements and recommendations of the following codes and standards.

a. American Society of Heating, Refrigeration and Air Conditioning Engineers Guide.b. Sheet Metal and Air Conditioning Contractor's National Association (SMACNA), Duct Manual and Sheetmetal Construction for Ventilating and Air Conditioning Systems.

PBNP VNPAB and CREFS Seismic Verification Page 7 of 167 S&A Report No. 09Q0839-R-001 Revision 0 2. All dampers shall be products of reputable manufacturers.

3. Rectangular ducts shall be constructed of galvanized steel in accordance with the latest standards of the American Society of Heating, Refrigeration and Air Conditioning Engineers and the SMACNA requirements for low, medium and high-pressure systems. Round ducts shall be either galvanized steel spiral pipe with four-ply lockseams, or galvanized metal sheets with continuous butt-welded seams reinforced with angular hoop braces. The CREFS and VNPAB HVAC systems are designed as low-pressure systems.4. Hangers and supports shall be designed to support the weight of the duct or.equipment and shall have a minimum factor of safety of five based on ultimate tensile strength of material used.5. Support spacing for ducts shall not exceed approximately;

a. 96" for ducts whose greater dimension is under 18" b. 66" plus or minus for ducts 18" -60" on the maximum side.The SRT walkdown SEWS are provided in an attachment to this report.As part of the walkdown the SRT enlisted the help of the PBNP Ventilation System Engineer who is experienced in HVAC duct construction in order to identify and confirm the type of duct joints used in the construction of the ductwork.

The results of this effort are discussed in Section 6.1.3 of this report.Additionally the SRT enlisted the services of the PBNP ISI group in order to confirm the sheet metal gage used for the ductwork.

The SRT selected 5 locations in the PAB and one location on the CREFS for ultrasonic testing in order to confirm that the ductwork gage met SMACNA requirements.

Specification 6118-M-41 requires that the gage of the duct is two gages heavier than that required by SMACNA. Ductwork for the VNPAB and the CREFS were tested using ultrasonic testing with the following results as shown in the table below: Duct Location Measured (in) SMACNA 6118-M-41 Spec Dimension Required Required 104" PAB EL 8' 0.057 (17 gage) 0.0516 (18gage) 0.0635 (16 gage)Area 4 76" PAB EL 8' 0.053 0.0396 (20 gage) 0.0516 (18 gage)Area 4 56" PAB EL 8' 0.043 0.0396 (20 gage) 0.0516 (18 gage)Area 4 48" PAB EL 8' 0.043 0.0336 (22 gage) 0.0396 (20 gage)Area 4 10" PAB EL 8' 0.033 0.0217 (26 gage) 0.0276 (24 gage)Area 4 54" CREFS 0.040 0.0336 (22 gage) 0.0396 (20 gage)Recirc Duct I The data show that the actual ductwork gages always exceed the SMACNA minimum required gages but not always by 2 gages. Sometimes the actual gage appears to be only one gage heavier. This could also be attributable to measurement precision.

For this evaluation the SMACNA minimum gages will be used for the pressure evaluations PBNP VNPAB and CREFS Seismic Verification Page 8 of 167 S&A Report No. 09Q0839-R-001 Revision 0 which is conservative.

Specification 6118-M-41 gages will conservatively be used for the dead load and seismic evaluations.

6.0 Walkdown

and Screening Results As described in Section 2.0 the methodology in EPRI report "Seismic Evaluation Guidelines for HVAC Duct and Damper Systems, Revision to 1007896" was used to evaluate the seismic adequacy of the CREFS and Primary Auxiliary Building Ventilation System (VNPAB).The function of the VNPAB exhaust ductwork is to remove and process air from the PAB. The function of the CREFS ductwork is to provide filtered air to the Control Room.Ductwork must remain intact during and after a seismic event. Duct distortions should not be large enough to restrict airflow. The walkdowns were performed considering these functional criteria.As previously discussed the HVAC ductwork and plena for most of the CREFS are covered with a lightweight insulating material that obstructs viewing of some of the duct supports and duct stiffeners.

The material is in place not only for insulation but also to improve the leak tightness of the system. However, the recirculation duct for the CREFS is un-insulated which allowed the Seismic Review Team (SRT) to examine the construction, stiffener spacing, hanger spacing and type, and material condition of the ductwork.

This examination of the recirculation duct indicated the same type and quality of construction as that found for the VNPAB system; therefore the SRT considered it reasonable to adjudge that the number and location of CREFS stiffeners and duct supports within the insulated CREFS systems conform to the SMACNA code (Reference

4) and Reference 3 requirements and that the duct construction is adequate.The dead load, seismic and pressure stresses in the CREFS ducts, duct stiffeners, and duct supports were evaluated based on this approach.This section addresses the structural integrity review, structural support system review, dampers, seismic interaction review, and pressure boundary integrity review. Figures 2 through 8 show the VNPAB exhaust and CREFS ductwork along with duct numbers used in the evaluation.

6.1 Structural

Integrity Review This section describes the analytical and walkdown results for the HVAC duct and duct support attributes that were examined by the SRT during the screening walkdowns.

Section 6.1.1 addresses the stresses in the ducts:.- Sections 6.2.1 and 6.5 address the duct support stresses and the pressure stresses in the ducts.6.1.1 Duct Stresses Analytical evaluations were performed on HVAC duct and support configurations in accordance with the methodology given in Section 4 of Reference

2. These evaluations are documented in Reference 5.The duct evaluation criteria are based primarily on the design approach used in SMACNA's construction standards for round and rectangular duct. The pressure boundary integrity review of the HVAC duct considers the combined effects of pressure, dead weight and seismic loads on the duct. The combined dead load and seismic stress PBNP VNPAB and CREFS Seismic Verification Page 9 of 167 S&A Report No. 09Q0839-R-001 Revision 0 is checked against a factored allowable working stress for acceptance.

Seismic stresses were determined using an equivalent static load approach.

The allowable bending stress is 8 ksi for carbon steel per Reference 2.-Duct spans influence the seismic and dead load stresses in the duct. Reference 2, Appendix C provides the allowable span length criteria using the analytical guidelines presented Reference 2, Section 4. This criteria was used to check the HVAC duct spans.Duct sections were evaluated in Reference 5 for dead load and seismic stresses using the methodology of Reference 2 when the duct has 3 or more spans. Ducts with less than 3 spans or cantilevered sections were evaluated similarly using equations that reflect the actual span conditions.

The initial assessment was performed using the peak acceleration

'g' value for the applicable area of the plant. Only five duct sections exceeded the allowable stresses for the initial evaluation.

Of the five, three sections are cantilevers and are discussed in Section 6.1.7. The other two sections were found acceptable when evaluated considering actual duct frequency and corresponding acceleration values or using actual duct density.6.1.2 Tie Downs VNPAB ductwork is often not positively secured to the horizontal angle cross-member of the trapeze hangers. As discussed in Sections 3 and 6, it is assumed that the CREFS ductwork has similar anchorage construction.

The SRT judged that this is unimportant since most hangers consist of trapeze supports that "capture" the ductwork between the vertical support rods thereby ensuring that the ducts cannot fall off the hanger during a seismic event. The last hangers on cantilevered or terminated ducts in the PAB were examined and found to be positively secured to the end hanger.6.1.3 Joints As part of the walkdown the SRT enlisted the help of a PBNP Ventilation System Engineer who is experienced in HVAC duct construction in order to identify and confirm the type of duct joints used in the construction of the ductwork.

The following joints were identified in the field: 1. Drive Slip (No. T-1, Fig. 3-1, Reference 2)2. Standing S (No. T-10, Fig. 3-1, Reference 2)3. Standing S (ALT) (No. T-1 1, Fig. 3-1, Reference 2)The VNPAB ductwork has Drive Slip joints that are in place on all 4 sides of smaller rectangular ducts and on the vertical sides of larger rectangular ducts. Standing S and Standing S (ALT) joints are provided on the top and bottom sides of larger rectangular ducts.The normal allowable bending stress for rectangular ducts may be increased by a factor of 1.7 for DBE loads as discussed in Section 4.1 of Reference

2. However as discussed in Section 4.2.1 of Reference 2 the use of Standing S and Standing S (ALT) duct joints requires the use of a 1.0 factor for the normal allowable bending stress.As discussed in Sections 3 and 6 it is assumed that the CREFS ductwork is constructed similarly to the VNPAB ductwork.

PBNP VNPAB and CREFS Seismic Verification Page 10 of 167 S&A Report No. 09Q0839-R-001 Revision 0 6.1.4 Appurtenances The SRT observed one large appurtenance attached to the VNPAB ductwork at the entrance of Pipeway 3 (Photo 1). The appurtenance consisted of a 6" diameter capped pipe approximately 3' long which is attached to the side of the duct. This pipe is assumed to be used as a temporary ventilation connection to the duct. It was also determined that the pipe is attached to a nearby post and therefore would not significantly load the duct. The SRT judged this to be acceptable.

VNPAB duct access doors and registers appeared to be adequately fastened and attached.The SRT also observed a large damper located in the mid-span portion of the CREFS ductwork that runs from the charcoal filter plenum to the plenum containing fans W-13B1 and W-13B2. The duct and damper at this location are structurally anchored to the concrete ceiling and was judged to be seismically acceptable (Photo 2). CREFS duct access doors and registers appeared to be adequately fastened and attached.6.1.5 Flexibly Mounted Heaw Equipment The CREFS fans W-14A and W-14B and W-13B1 and W-13B2 are mounted on vibration isolators (see SEWS) and have been determined to be outliers.

The anchorage for these fans will be modified in order to provide an adequate connection for lateral seismic loads.The anchorages for the four large fans in the PAB were previously modified to remove the vibration isolators.

As shown on the SEWS for Fans W-30A and W-30B the new anchorage was designed for the lateral seismic loads. Fans W-21A and W-21B were also modified however it was not clear if after reviewing plant documentation that the anchorage was seismically designed.

The SEWS for Fans W-21A and W-21B includes a calculation confirming the seismic adequacy of the anchorage.

The SRT observed the expansion joints connecting the ductwork to fans W-21 A, W-21 B, W30A and W30B. The expansion joints appeared to be rugged and in excellent condition.

Sufficient

'slack' is available to accommodate the small seismic duct movements; therefore the expansion joints are acceptable..

6.1.6 Branch

Flexibility VNPAB main ductwork has a number of locations where small branch ducts or pipes are attached to provide exhausts for small rooms and/or sumps. The seismic lateral displacements of the main ducts were computed at these locations and they were determined to be less than 3/8". Therefore, branch flexibility is determined to be acceptable.

No branch lines or hard spots for the CREFS ductwork were observed by the SRT.

PBNP VNPAB and CREFS Seismic Verification Page 11 of 167 S&A Report No. 09Q0839-R-001 Revision 0 6.1.7 Cantilevered Ducts The VNPAB ductwork has a number of small cantilever ducts that terminate in open areas or pipeways or small rooms. Larger ducts are cantilevered in the fan rooms above the W-21 A & B and W-30 A & B fans. The CREFS has one cantilevered duct. These ducts were evaluated in Reference

5. The results are listed below: " The ducts in Pipeways 3 and 4 require the addition of a lateral support at the end of these cantilevers.

• The ducts above the W-21 A & B and W-30 A & B fans are found to be seismically adequate.* Two small ducts had ductwork that extended up to 4' beyond the last hanger.This condition was found to seismically adequate." The intake duct for CREFS requires a lateral support at the flexible entry point to the filter plenum.6.1.8 Duct Corrosion The SRT did not observe any instances of duct corrosion in the PAB and found the material condition of the ductwork and duct hangers to be very good in general.The only corrosion observation was in the CREFS on the anchorage of fans W13B1 and W13B2. This anchorage will be replaced as part of the seismic upgrade of the fan anchorages.

6.2 Support

System Review This section describes the results of the duct support analysis and the results of the walkdown for the support attributes discussed below.6.2.1 Duct Support Assessment Duct supports are found to consist primarily of trapeze supports made up of angles supported by threaded rods anchored to the concrete with concrete expansion anchors.In some case the rods are welded directly to steel embedded plates or other steel members. In some cases wall brackets made up of angle sections are also used.The supports were evaluated using the methodology included in Appendix F of Reference

2. Checks were performed for the following:

• Dead load check* Vertical capacity check* Ductility check* Rod hanger fatigue The results of the review are provided in Reference

5. Supports that require modification are discussed in Section 9, Outliers.The dead load check for the supports performed in Reference 5 included evaluations of the threaded rods, shell anchors, and angle members. Based on the SRT walkdown, the minimum diameter for the threaded rods and shell anchors is 3/8 inch and the PBNP VNPAB and CREFS Seismic Verification Page 12 of 167 S&A Report No. 09Q0839-R-001 Revision 0 minimum angle size is L2x2x1/8.

The evaluations were performed considering an average tributary span for the vertical supports using the minimum size of the component.

The evaluations were in accordance with the AISC Manual of Steel Construction 9 th Edition (Reference

7) and the Generic Implementation Procedure (GIP)for Seismic Verification of Nuclear Plant Equipment (Reference 8). All supports satisfied normal allowable stresses for the rods and shells. All supports satisfied the conservative evaluation for the angle members with the exception of six duct spans. Detailed evaluations were performed for these six sections considering a realistic weight distribution on the angle member and they were also found acceptable.

The vertical capacity check (5 times dead load) for the supports performed in Reference 5 included evaluations of the rods and shell anchors in accordance with Reference 2.The vertical capacity check focuses on the weak link in the support. Per Reference 5, the shell anchor capacity (per Reference

8) controlled over the threaded rod capacity (per Reference 7). All supports for all duct sections met the vertical capacity check.The walkdown performed by the SRT indicated that the support configurations were primarily rod hanger trapeze supports.

In accordance with Reference 2, supports constructed of threaded steel rods with fixed-end connections details behave in a ductile manner under horizontal motion. No additional ductility check is required and no hard spots were identified.

The rod fatigue evaluation is discussed in Section 6.2.9.6.2.2 Beam clamps The use of beams clamps was observed in an extremely small number of cases. In each case the clamp was oriented properly to preclude the clamp from slipping off the member it is connected to in a seismic event and therefore found to be acceptable.

6.2.3 Channel

Nuts The large majority of duct supports for the VNPAB and CREFS consist of threaded rod trapeze supports.

Except for one hanger in the PAB Containment Spray Pump area the SRT did not observe the use of strut materials that would require the use of channel nuts. The noted hanger is assessed in LAR 6 and it is recommended to replace this hanger with a standard trapeze support.6.2.4 Cast Iron Anchor Embedment The use of cast iron embedments was not observed by the SRT.6.2.5 Broken Hardware One case of broken hardware was observed by the SRT (PAB, Unit 2, at the floor penetration adjacent to RHR cubicle).

This item was reported to the station and will be repaired by PBNP under CAP 01157521.

PBNP VNPAB and CREFS Seismic Verification Page 13 of 167 S&A Report No. 09Q0839-R-001 Revision 0 6.2.6 Support Corrosion No duct support corrosion was observed by the SRT.6.2 7 Concrete Quality The VNPAB and CREFS HVAC systems are supported primarily from the reinforced concrete floors (above and below) and walls in proximity to the ducts, plenums, fans and duct supports.

The material condition of the concrete was found to be excellent by the SRT.6.2.8 Welded Attachments Welded duct attachments were not observed by the SRT 6.2.9 Rod Hanger Fatigue Rod fatigue evaluations were performed in accordance with Reference 2, Appendix E.An evaluation was completed for the supports in the Auxiliary Building, in Pipeways 3, and 4 (Pipeway 1 has no rod hangers), and in the Control Room. The applicable 5%damped spectra was conservatively considered as enveloped by the 0.75g Bounding Rod Fatigue Spectra (Figure E-1 of Reference

2) for all areas except the Auxiliary Building Central where the applicable spectra was enveloped by the 0.5g Bounding Rod Fatigue Spectra. The screening chart for 3/8 inch diameter rods (Figure E-3) of Reference 2 indicated that all the rod supports were below the bounding values for weight and length.Based on the above the rod fatigue check was performed and found to be acceptable.

6.3 Dampers.The dampers installed at PBNP consist primarily of curtain type fire dampers manufactured by Pacific Air Products (Reference

6) that are mounted in the ducts as they pass through concrete firewalls.

The dampers were found to be to be rugged and are typical of those in the Earthquake Experience Equipment Class. The operators and actuators of other miscellaneous dampers are not constructed of cast iron and there is sufficient slack and flexibility for attached lines. The dampers appeared to be well anchored into the supporting concrete walls and damper operation will not be hindered by duct distortion.

Photo 3 shows a typical duct/damper installation.

6.4 Seismic

Interaction The VNPAB ductwork is located in the PAB that contains Safety Related systems, structures and components (SSC). As such, these SSCs are seismically designed.

The SRT did not identify any falling hazards or credible differential displacement hazards.Any small lines attached to the ductwork contained enough flexibility to absorb the small seismic displacements of the ductwork.The CREFS ductwork is located in the Control Building Mechanical Equipment Room that is constructed of rugged reinforced concrete walls and slabs. The SRT did not identify any falling hazards or credible differential displacement hazards. Any small lines PBNP VNPAB and CREFS Seismic Verification Page 14 of 167 S&A Report No. 09Q0839-R-001 Revision 0 attached to the ductwork contained enough flexibility to absorb the very small seismic displacements of the ductwork.A conservative maximum lateral displacement was computed in Reference 5 by using long span duct sections with small cross sections.

The displacement was determined to be less than 3/8 inch. This displacement is judged to be sufficiently small so as not to create any significant duct impact issues.6.5 Pressure Boundary Inte-grity Review As stated in Reference 2 earthquake experience and test data have demonstrated that duct systems that meet the SMACNA requirements performed well during earthquakes.

The Design Specification (Reference

3) for the VNPAB and CREFS HAVC systems required that the ductwork be designed in accordance with SMACNA requirements.

The SRT's walkdown included reviewing the sheetmetal gage, stiffener size and spacing, and duct dimensions to confirm the adherence to the SMACNA requirements.

Project calculations (Reference

5) were performed and confirmed that the duct stresses and duct stiffener stresses due to pressure loads are within the Reference 2 guidelines with the exception of Duct No 37. Per the walkdown notes, the top stiffeners for this duct are missing and must be installed at 2 locations along the duct span.7.0 Selection of Bounding Configurations This section addresses the selection of the bounding configurations for supports and ducts for limited analytical review and the treatment of inaccessible ducts.7.1 Bounding Configurations (LARs)The SRT selected seven support configurations and one bounding duct configuration that were judged to be unusual or heavily loaded for Limited Analytical Review (LAR).The LARs and the LAR tracking form are included as attachments to this report.In addition all trapeze supports which are not evaluated in LARs were evaluated and found to be acceptable for the assessment criteria's dead load check and the 5 times dead load check (Vertical Capacity Check).LAR 1 addresses a support for the 104x26 duct (Duct No. 1) that also supports one of the rods for an additional duct (52x22). The evaluation for dead load indicates that even when performing a detailed evaluation, the support angle is overstressed.

The proposed solution is to add a new hanger at or near the existing hanger. The shell anchors did not meet the acceptance criteria for the vertical capacity check (5 times dead load) however a detailed lateral load evaluation was performed and the shell anchors were found to be acceptable.

Since the shell anchors did not meet the initial acceptance criteria, the support is classified as an outlier (see Section 9.0 for additional discussion).

LAR 2 addresses a support for the 76x20 duct (Duct No. 4) that also supports a 72x14 duct, a 1 0x6 duct, and a 6" diameter steam pipe. All components of the support were acceptable for the dead load check. The 1/2 inch diameter shell anchors did not meet the acceptance criteria for the vertical capacity check (5 times dead load) however a detailed lateral load evaluation was performed and the shell anchors were found to be PBNP VNPAB and CREFS Seismic Verification Page 15 of 167 S&A Report No. 09Q0839-R-001 Revision 0 acceptable.

Since the shell anchors did not meet the initial acceptance criteria, the support is classified as an outlier (see Section 9.0 for additional discussion).

LAR 3 addresses a support for the 40x20 duct (Duct No. 16) that is attached to a cable tray support. Based on the relatively small weight applied to the support from the duct and the robust nature of the cable tray support, the support is acceptable by engineering judgment.LAR 4 and LAR 5 address supports on the 54 inch diameter ductwork that leads to the Auxiliary Building Vent Stack. The supports are found to be acceptable.

LAR 6 addresses a support for the 34x14 duct (Duct No. 14). This support consists of a P1000 unistrut member that is connected by friction clamps to vertical conduits.

The configuration is unacceptable by engineering judgment due to~the orientation of the vertical orientation of the clamps and is considered an outlier. The unistrut member has a long span and also supports other miscellaneous components.

The resolution for this LAR is to add a new trapeze support in very close proximity to the existing support.LAR 7 supports a 26x16 duct (Duct No. 26) with a knee brace configuration that attaches to another duct support. Both ducts are supported by 2 rods that are attached to shell anchors in the ceiling. The knee brace configuration is unacceptable for dead load and is considered an outlier. All other components are acceptable for dead load and the vertical capacity check (5 times dead load). The resolution is to replace-the existing knee brace with a more robust steel support.LAR 8 evaluated the longitudinal seismic stresses of the heaviest duct section with a significantly long span. It was found to be acceptable' Reference 2 states that when the selected configurations do not pass the analytical review, the selected population should be expanded.

Several supports did not pass the analytical review requirements however all duct sections and supports were analyzed for the stresses due to dead load, seismic and pressure stresses.

Therefore the requirement for expanding the selected population was satisfied.

Reference 5 provides the results of the assessment.

7.2 Inaccessible

Ducts A small amount of ductwork was found to be inaccessible due to being in locked radiation areas or visually blocked by overhead items and construction scaffolds.

These ducts have small cross sections and are very lightweight.

Given this condition and based on the construction of the majority of the ducts and hangers that were examined during the walkdown, these inaccessible ducts were judged to be acceptable by the SRT.

PBNP VNPAB and CREFS Seismic Verification S&A Report No. 09Q0839-R-001 Revision 0 Page 16 of 167 These ducts are described in the following table.Duct Location Duct Size Remarks PAB EL. 8', Unit 1, 1 Hx 8" Dia Small diameter lightweight duct that terminates 3 A-B Room (M-1 19) in the room. OK by SRT judgment.PAB EL. 8', Unit 2, 2Hx 1 O"x 8" Small lightweight duct that terminates in the 3 A-B Room (M-1 19) room. OK by SRT judgment.PAB EL. 8' and 26', 14" x 6" Small lightweight duct that runs from PAB EL.aisle way at EL. 8' and 8' to Pipeway 3. Visible portions appear to be ducting to and in well constructed and well supported.

Duct Pipeway 3 terminates in Pipeway 3. See Section 9.1.3 for (M- 119) discussion on appurtenance.

Ok by SRT judgment.8.0 Miscellaneous Miscellaneous items in addition to the VNPAB and CREFS ductwork and fans were examined by the SRT and are discussed below." MCCs for fans W-13 B1 & B2, W-14 A & B, W21 A & B and W30 A &B MCCS for the above listed fans were seismically evaluated during the PBNP initial SQUG program. The MCCs were found to be seismically adequate.

The SEWS for MCCs 2B-42, 1 B-42, 1 B-32 and 2B-32 documenting the seismic verification of these components are included as an attachment to this report.The original SEWS for MCC 2B-42 required that the bolting for the MCC top supports be tightened.

The SRT reviewed the top anchorage and confirmed that all visible top anchorage is now in place and tight." PAB Exhaust Stack The PAB exhaust stack is a tall steel plate stack that is located in the fagade. The stack is laterally braced at two points. The exhaust stack was evaluated in Reference 5 and found to be seismically adequate.* Control Panel C-67 Control Panel C-67 provides the controls for the CREFS fans and dampers. This panel was examined by the SRT and found to be seismically adequate.

The SEWS for this panel is included as an attachment to this report.* Plena for Fans W-14 A & B and W-13 B1 & B2 The plena for the listed fans were examined by the SRT and found to be seismically adequate.

The evaluation of the plena is given in the SEWS for the subject fans.

PBNP VNPAB and CREFS Seismic Verification Page 17 of 167 S&A Report No. 09Q0839-R-001 Revision 0" Roof Intake Enclosure for CREFS HVAC The CREFS air intake consists of ductwork, which penetrates the roof of the HVAC room in the Turbine Building.

The ductwork then penetrates the west wall of the Turbine Building and terminates in a louvered metal enclosure.

The SRT examined the ductwork above the HVAC Room (Photo 4) and found it to be rugged and judged seismically adequate.

The intake enclosure is a relatively light gage enclosure that was also judged as seismically adequate." Charcoal Filter in W30 Fan Room The SRT examined the charcoal filter for Fans W-30 A & B. In the same room (about 20 ft away) there are charcoal filter banks with a footprint of 107" x 180". The visible 107" side has 10 -1/2" concrete expansion anchors with two anchors having nuts that are raised. The 180" side cannot be fully viewed as it is adjacent to a wall but at least 10 anchors were counted, some of which again were missing nuts or for which the nuts were raised. The two other sides are inaccessible.

The filter banks are about 10' high and are adjudged to have a natural frequency in excess of about 20 Hz. Since filter banks cannot uplift the anchors only need to resist base shear. There are a sufficient number of anchors visible to accomplish this therefore the filter banks are declared seismically adequate.The SEWS for Fans W-30 A & B include the charcoal filter assessment.

9.0 Outliers

No additional resolution required.Note: A broken duct (Duct No. 39) support at the floor penetration near column line P/13 was reported to PBNP and will be repaired (see CAP 01157521)HVAC System Outlier Sheets (HSOS) for each outlier are included as attachments to this report..10.0 Conclusion The CREFS and VNPAB exhaust systems were seismically verified using the guidelines and criteria in Reference

2. The ducts, dampers, fans, and supports for the subject systems are found to be acceptable for the application of Reference

2. Systems temperatures and PBNP seismic motions are also found to be acceptable.

The SRT consisted of experienced, licensed engineers with the appropriate required SQUG GIP qualifications.

Dr. Robert P. Kennedy performed the required Peer Review of the seismic verification.

Dr. Kennedy's report (Reference

11) is provided in Attachment 12.6 and concludes that as long as outlier issues are resolved the reviewed ductwork and associated components will be seismically adequate for the PBNP seismic design ground motion level.In plant screening walkdowns regarding HVAC system and duct support structural integrity were performed by the SRT in accordance with the Reference 2 guidelines.

SEWS were developed for the components and ductwork included in walkdown.Calculations were performed to ensure that duct stresses due to dead load, seismic and pressure loads met the Reference 2 acceptance criteria.

Limited analytical review cases were select and analyzed for duct support and duct configurations.

Duct supports were evaluated for dead load, vertical capacity check, and rod fatigue.Outliers were identified that required upgrades.

The appropriate documentation was put in place to track each outlier upgrade or modification.

PBNP VNPAB and CREFS Seismic Verification Page 19 of 167 S&A Report No. 09Q0839-R-001 Revision 0 Based on the above it has been determined that the PBNP CREFS and VNPAB exhaust system ductwork, supports, and associated components are seismically adequate for the PBNP earthquake pending the installation of the modifications to resolve the outliers.11.0 References

The new buckets are of the same configuration as the existing buckets. The buckets are mounted into existing MCC's in the same manner as the existing buckets. Thus, the buckets themselves are qualified by comparison to the existing buckets.Seismic Evaluation of Design Change: Seismic Qualification Review Report, SQRR, SQ-002079, evaluated the applicability of the Cutler-Hammer seismic testing that is documented therein. The test report is applicable to the components tested provided they are used in MCCs and located where the Floor Response Spectra is <= that of the PAB 26 ft. Since 2B-42 is located in the PAB, el 26 ft, the Cutler-Hammer test report can be used to qualify the components listed in the attached table.The seismic qualification records for 21-42 are the Rev. 0, 1, 2 and 3 SEWS.

Rev 2, Corrected, 2/14/92 Status: Yes Sheet 4 of 4 This modification will require the installation of new MCC breaker bucket 1B52-3213F in MCC 1B32.The new bucket will be placed in current spaces 1BOO-3213D and 1BOO-3213F.

Seismic Evaluation of Change: The components in the bucket are as follows: 1. Cutler Hammer model HFD3015 breaker.2. Cutler Hammer series A200 starter.3. Cutler Hammer model C0150E2AXX control power transformer.

4. Terminal block rated for 600 Vac and 40 A.5. Bussmann BAF style control power fuse (3 Amp).The breaker, starter, control power transformer and terminal block were tested by Trentec as documented in SQ-002079.

Trentec also tested a 1A and 6A style BAF fuse. The 3A fuse used here is comparable to the fuses tested and is acceptable by comparison to the tested fuses. Therefore, all the components in the breaker are seismically qualified.

As part of the original USI A-46 seismic evaluation for IB-32, the anchorage calculation (using Anchor Version 4.0) for 1B-32 estimated a weight of 800# per MCC section. The replacement CPTs (Control Power Tranformers) installed in MR 96-032 (See Rev. 2 SEWS) increase the weight of the MCC by about 175# from an estimated 5600# to 5775#. The new bucket being added in this modification weighs less than 100# (estimated).

The total load increase from this modificai"bn and MR 96-032 is approximately 5% of the total MCC load. The original anchorage calculation had a minimum safety factor of 2.474. This load increase will have a negligible affect on the safety factors. Therefore the anchors are acceptable for the revised loads.The seismic qualification record for IB-32 is the Rev. 0, 1, 2, & 3 SEWS.This evaluationvis identified as SQ-002167.

Replace/upgrade MCC buckets Description of Design Change: The scope of this modification is to replace Motor Control Center (MCC) 1B-42 breaker buckets 1B52-421B, IF, 1J, 2C, 2F, 2J, 3C, 3F, 3J, 4F, 4J, 4M, 5J, 5M, 6C, 6F, 6M, 7C, 7F, 8K, 8M, 9M, 10C, 10F, 1 lB and I IF with new Cutler Hammer (C/H) breaker buckets. These new buckets shall be equipped with the same components as the existing buckets (i.e. breaker, starter, transformer, etc.); however, the new breaker will have an interrupting capability higher than the available short circuit current. In addition, this modification will replace the SPACE door covers for cubicles IB00-42 IC, 6J, 7H, 9F, 9H, 1OM, 1 ID, 11 G, 12B, 12D and 12G. All other MCC 1B-42 breaker buckets will be replaced by MR 01-128*D;The purpose of this modification is to improve personnel and equipment protection by replacing the IB-42 breakers that have been identified as being overdutied under maximum fault conditions in PBNP Calculation Addendum N-97-0154-00-A, "Refinements to Electrical AC Power Distribution System Short Circuit Analysis." It should also be noted that this modification is one of many modifications (MR 01-128*A-S) that will resolve maximum fault conditions concerns identified by calculation addendum N-97-0154-00-A.

The components of the replacement buckets have been seismically qualified by shake table testing. The test report has been evaluated by SQRR and is documented on SQ-002079.

The new buckets are supported in the MCC in the same manner as the existing buckets.The doors in front of spaces, (i.e., those places in the MCC where there is no bucket), will be replaced, with new doors. The existing doors are held in place by a minimum of two (2) screws. The new doors will be held in place on one side by a minimum of one (1) hinge, which is attached to the MCC cabinet PBNP VNPAB and CREFS Seismic Verification Page 49 of 167 S&A Report No. 09Q0839-R-001 Revision 0 GIP Rev 2, Corrected, 2/14/92 SCREENING EVALUATION WORK SHEET (SEWS) Status: Yes Sheet 5 of 7 ID : 1 B-42 ( Rev. 4 Class : 1.

The other side of the door is held in place by a minimum of one screw. This arrangement is the same as used on the doors in front of the MCC buckets.CAVEATS: MCC/BS Caveat 8 -Doors/Buckets secured. The JWP's listed in the references above, contain steps in section 3.0 to document re-engaging the mounting screws and closing of the door.MCC/BS Caveat 11 -The MCC's contain relays and other seismically sensitive equipment.

All these items were seismically qualified by shake table testing, see the SQRR in SQ-002079 INTEACTION EFECTS: 1. The MCC buckets are internal to the MCC. Therefore, no new soft targets are created. The replacement doors are made of steel, and do not contain soft targets.2. The MCC's contain relays and other seismically sensitive equipment.

All these items were seismically qualified by shake table testing, see the SQRR in SQ-002079.

3. No new lines were attached by mod MR 01-128*C 4. No new otherhead equipment was added by mod MR 01-128*C.Seismic Evaluation of Design Change: The original A-46 SEWS, SQ-000020, was reviewed.

It refers to WE calculation 85-010, rev. 01 for justification of the anchorage for the MCC's. The calculation uses an estimated weight for the MCC.The new MCC buckets do not weigh significantly more than the existing MCC buckets. Therefore, the existing calculation is still acceptable for providing justification for the MCC.The mounting of the existing MCC buckets in the MCC was compared to the mounting of the new buckets. The new buckets are supported by the MCC in the same manner in which the existing buckets are mounted. The new buckets do not require any changes to the MCC. Four (4) points, two (2) on each side of the bucket, support both the existing and new buckets. Both old and new buckets have a retaining latch at the front of the bucket. Thus, the new buckets are similar to those in the existing earthquake data base (MCC/BS Caveat 1).The new doors are held in place by at least one hinge, with two screws, and at least one screw on the opposite side from the hinge. This arrangement is the same as that for the doors in front of buckets. The SRT has evaluated this arrangement as being sufficient to hold the door closed during a seismic event.SRT has determined that the MCC has sufficient strength capacity to remain functional before, during and after a seismic event.Subcomponents:

A local FVR starter with transformer will be installed in the new local control panel NSW-4478 near the valve. NSW-4478 will also contain a three-position spring-return-to-center control switch for local operation, valve position indication lights, and terminal blocks. New cables will be run in existing cable trays JU06 through JU13, and FU03 through FU06. New cables will also run in new conduits.

A local disconnect switch B29-SW-4478 will be installed near NSW-4478.

And a new pull box PB-4478 will be installed near the valve SW-4478.2. IWP 98-024*H-02:

a) Assemble and install new local control panel NSW-4478.b) Remove spare 50A breaker and replace with 20A breaker in MCC 2B32, and install new wireway at the MCC (scope of this SEWS).c) Install new local disconnect switch B29-SW-4478.

d) Install new conduit and pull box PB-4478.e) Run new cables for MOV SW-4478 and associated components.

Seismic Qualification Evaluation:

This modification removes the spare 50A breaker and replaces it with a 20A breaker in the MCC, and installs a new wireway at one side of the MCC. The new wireway is is supported by three (3) cantilever supports through-a L2x2xl/4 angle using two (2) bolts. A N2544 Unistrut makes up the cantilever part of each suport, which attaches to a N 1000 Unistrut that is secured to the wall with two (2) 3/8" Hilti bolts.The 20A breaker is a typical component of MCCs, and therefore, is represented by the seismic experience database.The wireway supports were tug tested and detemined to be adequately installed.

No spacial interactions are observed.Based on the above discussion, the new breaker is acceptable.

The change does not affect the equipment weight or center of gravity. Previous anchorage evaluation is still valid.This document is identified as SQ-001702.

Panel C-67 controls CREFS HVAC room. It is a NEMA Hoffman box 66"H x 30"W x 12"D. It is anchored at the top with 2 -3/8" CEAs to concrete wall and secured to a knee-braced frame which in turn is anchored to concrete wall. This panel estimated weight is 500 lbs based on a density of 35 pcf and it is deemed rigid (fl> 33Hz). Each 3/8" anchor can resist about 1500 lbs so the gross seismic capacity is 6g ignoring the bottom anchorage.

Therefore, Panel C-67 is declared seismically adequate.No credible potential seismic interaction was noted.Evaluated by: W. Djordjevic, PE Date: 9/03/2009 P.A.Gazda, PE 9/03/2009

Ref. 1. Dwg No. P6118-M37-078-2 W1 3B1 & B2 are outliers.

They are located on rubber vibration isolators beneath C4xl.5" rails. The motors are restrained by z-clips and/or "top hat" clips longitudinally (axial w.r.t. direction of channel) and vertically (1/4" thick)but not transversely.

The fans have no restraint in any direction.

There are no vibration isolators.

They are each anchored by 6 -3/4" concrete expansion anchors. The footprint is 60" x 84" with 3 anchors spaced equally on each 60" side.Possible interactions are an overhead cast iron pipe, which is continuously supported such that it cannot credibly disengage from its supports to fall; and cable "pigtails" which are deemed too light to be of consequence even if they were to fall.Evaluated by: W.

W. Djordjevic

& P. A. Gazda (8/31/09)Ref. 1. S&A Calc. No. 98Q0020-C-001, Rev. 1., "PAB Fans W30A and W30B Anchorage Qualification" The W30A&B fans are also seismically designed (by Stevenson

& Associates, Ref. 1) with no vibration isolators.

In the same room (about 20 ft away) there are charcoal filter banks in the rooms with a footprint of 107" x 180".The visible 107" side has 10 -1" concrete expansion anchors with two anchors having nuts that are raised. The 180" side cannot be fully viewed as it is adjacent to a wall but at least 10,anchors were counted, some of which again were missing nuts or for which the nuts were raised. The two other sides are inaccessible.

The filter banks are about 10' high and are adjudged to have a natural frequency in excess of about 20 Hz. Since they cannot uplift the anchors only need to resist base shear and there are sufficient visible anchors to accomplish this so they are declared seismically adequate.

They pose no interaction potential risk to the fans.No issues found.No potential seismic interactions noted.Evaluated by: W. Djordjevic, PE Date: 8/31/09 P. A. Gazda, PE 8/31/09

W. Djordjevic

& P. A. Gazda (8/31/09)Ref. 1. S&A Calc. No. 98Q0020-C-001, Rev. 1., "PAB Fans W30A and W30B Anchorage Qualification" The W30A&B fans are also seismically designed (by Stevenson

& Associates, Ref. 1) with no vibration isolators.

In the same room (about 20 ft away) there are charcoal filter banks in the rooms with a footprint of 107" x 180".The visible 107" side has 10 -11/2" concrete expansion anchors with two anchors having nuts that are raised. The 180" side cannot be fully viewed as it is adjacent to a wall but at least 10 anchors were counted, some of which again were missing nuts or for which the nuts were raised. The two other sides are inaccessible.

The filter banks are about 10' high and are adjudged to have a natural frequency in excess of about 20 Hz. Since they cannot uplift the anchors only need to resist base shear and there are sufficient visible anchors to accomplish this so they are declared seismically adequate.

They pose no interaction potential risk to the fans.No issues found.No potential seismic interactions noted.Evaluated by: W. Djordjevic, PE Date: 8/31/09 P. A. Gazda, PE 8/31/09

The material is in place not only for insulation but also to improve the leak tightness of the system. However, the recirculation duct for the CREFS is un-insulated which allowed the SRT to examine the construction, stiffener spacing, hanger spacing and type, and material condition of the ductwork.

This examination of the recirculation duct indicated the same type and quality of construction as that found for the VNPAB system; therefore the SRT considered it reasonable to adjudge that the numberand location of CREFS stiffeners and duct supports within the insulated CREFS systems conform to the SMACNA code requirements and that the duct construction is adequate.

The dead load, seismic and pressure stresses in the CREFS ducts, duct stiffeners, and duct supports were evaluated based on this approach.2) The intake duct is separated from the charcoal filter plenum by a rubber bellows therefore the duct is a cantilever in the lateral direction.

-Outlier 3) The control room ceiling ducts and bathroom exhaust were examined by the SRT. Ceiling panels were removed to examine the ducts. The ducts vary in size from 24"x24" to approximately 16"x10". The small ducts are generally supported by strut anchors on approximately 8' centers. These insulated ducts are very lightweight and are judged acceptable by the SRT.In general all Control Room ceiling and bathroom exhaust ducts appear well constructed and well supported and judged OK by SRT.CERTIFICATION: (Signatures of at least two Seismic Capability Engineers are required; one of whom is a licensed professional engineer.)

Kennedy October 29, 2009 1. Introduction I have performed an independent peer review of the seismic verification of the Point Beach Nuclear Plant (PBNP) Primary Auxiliary Building Exhaust (VNPAB) and Control Room Emergency Filtration System (CREFS) ductwork, associated supports, and components documented in Refs. 1 and 2. This seismic verification was conducted by Mr. Walter Djordievic and Mr. Phil Gazda of Stevenson

& Associates (S&A) and was performed in accordance with the criteria presented in Ref. 3. I am very familiar with the qualifications of both Messrs. Djordjevic and Gazda and can attest to their qualifications to perform these seismic verifications in accordance with the Ref. 3 criteria.Previously (February 7, 2004), I performed a peer review of the seismic evaluation guidelines presented in an earlier version of Ref. 3. All of my previous review comments have been incorporated into Ref. 3. Therefore, I support the use of the Ref. 3 guidelines for the seismic verification of HVAC ductwork and damper systems.Within my experience, these Ref. 3 guidelines were initially applied for the seismic verification of the Turbine Building exhaust ductwork for Hatch Nuclear Plant Unit 1. I performed (November, 2004) the independent peer review of that seismic verification.

Subsequently, the U.S. Nuclear Regulatory Commission has accepted and approved this Hatch seismic verification of ductwork.A primary goal of my independent peer review of the Point Beach Nuclear Plant (PBNP) seismic verification of HVAC ductwork presented in Refs. I and 2 was to. verify that it was conducted in accordance with the criteria of Ref. 3 in at least the same degree of rigor as that previously performed for Hatch Unit 1.2. Scope of Peer Review Initially (September 25), 1 conducted a one day peer review seismic walkdown of the PBNP ductwork, associated supports, and component which were being assessed by the S&A engineers.

My walkdown was subsequent to the seismic walkdowns previously conducted by the S&A engineers.

I was accompanied by Mr. Phil Gazda of S&A during my walkdown.

The purpose of my walkdown was to assess:Structural Mechanics Consulting 28625 Mountain Meadow Road, Escondido, CA 92026 (760)751-3510

During my peer review seismic walkdown, I observed essentially 100% of all ductwork, and components being assessed by S&A engineers that were accessible outside of locked radiation areas. I also observed a significant fraction of ductwork supports visible from the floor. I did not request that fan plena be opened so that I could observe the fan mounting therein. However, through a review of the Seismic Evaluation Work Sheets (SEWS), I have confirmed that the Seismic Review Team (SRT) did open these fan plena and observed the fan mounting therein. For example, see the photos attached to the SEWS between Pages 70 and 123 of Ref. 1.In addition to my peer review walkdown, I have reviewed Ref. 1 which documents the seismic verification performed, and Ref. 2 which provides the analytical reviews performed for this verification.

The purpose of these reviews was to: (1) confirm compliance with the Ref. 3 guidelines, (2) fully understand the methodology and basis for any assumptions made by the SRT for situations which could not be observed, (3) appropriateness of all calculations, (4) completeness in describing and resolving outliers, and (5) adequacy of documentation of the seismic verification program.I did not perform any numerical check of calculations since such checks are a checker function, and not a peer review function.

However, I did note that all calculations do appropriately contain the initials of both the preparer and the reviewer.3. Overall Findings This experience based seismic verification of the Point Beach Nuclear Plant Primary Auxiliary Building exhaust and Control Room Emergency Filtration System ductwork, associated supports, and components is of very high quality. It fully complies with the guidelines of Ref. 3. The documentation is excellent.

The walkdown team performed a very thorough and competent evaluation.

I didn't identify any open issues PBNP VNPAB and CREFS Seismic Verification Page 167 of 167 S&A Report No. 09Q0839-R-001 Revision 0 not considered by the walkdown team. I concur with the methodology used, and all assumptions made by the SRT. I fully concur with the findings and conclusions of Ref. 1.So long as the outlier issues identified in Section 9 of Ref 1 are resolved as suggested therein, I have confidence in the seismic adequacy of the reviewed ductwork, supports, and associated components for the Point Beach Nuclear Plant design ground motion level.References
