M-663-00017A Page 4 of 13 Attachment D1 Revision W05 1.0 Purpose 1.1 The purpose of this document is to evaluate a unique fire barrier design for the hatch covers protecting the Containment post-tensioning openings at C Buttress. This evaluation was conducted in effort to satisfy regulatory expectation regarding qualification and documentation of fire barrier issues. This evaluation was conducted in accordance with the guidance of NRC Generic Letter 86-10.

5.0 Evaluation 5.1 Assessment of Condition to Design Requirements The floor slabs of the Auxiliary Building elevations 2026 and 2047 incorporate two hatchways that are located at each side of the containment Buttress C. These four openings are provided to permit access to the containment post- tensioning system tendons located at the same elevations as the floor slabs.

In effort to prevent fire propagation from one Fire Area to another, a steel plate protected on both sides by fireproofing material, covers each hatch opening. Hatch cover steel support members are also protected with fireproofing material. This protection arrangement along with the interface with the seismic expansion gap at the Containment Building wall presents a unique fire barrier configuration that is not directly bounded by fire testing. Therefore, further review is necessary to assess acceptability. Figures 1 and 2 from Reference 3.4 depict the design configuration for the hatch covers and support steel, including the interface with the seismic gap seal.

Also, depicted in Figure 3 from Reference 3.5 is an alternative design to allow access to the tendon covers without removing the enclosure design. This alternative design will permit access without damaging the fire protective material during tendon maintenance.

4. ALL EXPOSED STRUCTRUAL STEEL ITEMS SHALL BE FIRE PROOFED WITH 3-HOUR FIRE RATED ALBI-DURASPRAY PER MANUFACTURERS INSTRUCTIONS BOTTOM SIDE ONLY.

5.2 Evaluation of Condition 5.2.1 Hatch Cover Plate The bottom side of the 1/4 thick checker plate steel hatch covers and the heavy steel angle engaging the containment wall (slip joint) are protected with cementitious fire proofing. Cementitious fireproofing is also provided on the topside of one hatch, while the remaining three are protected with a 1 base layer of Thermo-Lag 330-1 on the topside.

The cementitious fireproofing thickness is provided in accordance with the requirements necessary to achieve a 3-hour rating for structural steel, which has less restrictive acceptance criteria (1,100°F for beams or 1,000°F columns) than the ASTM E 119 unexposed side requirements for a fire barrier (250qF plus ambient). Additionally, subsequent Thermo-Lag testing (Reference 3.10) has demonstrated that a 1 thick base layer panel achieves a 3-hour F rating and a 139-minute T rating when subjected to the fire barrier test requirements of ASTM E 119.

As discussed above, both materials satisfy a 3-hour F rating independent of each other. However, further review is necessary to assess temperature performance considering the combined affect of both materials collectively installed as a single protective barrier.

M-663-00017A Page 7 of 13 Attachment D1 Revision W05 When structural or steel enclosures protected with fireproofing material are integral to a fire barrier, only one barrier side will be exposed to the fire, thus limiting heat flux through the unexposed fireproofing. The unexposed fireproofing can be expected to provide a significant insulator as demonstrated by comparing the delta between furnace temperature and the maximum steel exposure temperature.

Where cementitious fireproofing is provided on both sides of the hatch cover, subtracting the furnace temperature (1,925qF) from actual thermocouple data (1,100qF) from References 3.8 and 3.9 yields an approximate 825qF temperature drop across the exposed fireproofing during ASTM E-119 fire endurance testing. By applying this temperature drop logic to the unexposed fireproofing, conservatively the same results will be achieved, yielding an expected temperature of 275qF to the unexposed side of the barrier. This estimated 275qF is below the maximum cold side temperature limitations required by ASTM E 119. Therefore, this protection configuration is considered 3-hour T rated.

Where a combination of cementitious fireproofing and Thermo-Lag 330-1 is utilized as hatch cover protection, temperature performance is based on a comparison to the Thermo-Lag test (Reference 3.10) that obtained a 139 minute T rating and the previously discussed thermal performance of cementitious fireproofing. Reference 3.10, for the Thermo-Lag wall test configuration, presented an average unexposed side temperature of 498qF at 3-hours. Subtracting the furnace temperature (1,925qF) from the unexposed side thermal performance of the Thermo-Lag barrier (498qF) yields an approximate 1427qF temperature drop across the exposed Thermo-Lag during ASTM E-119 fire endurance testing. Considering this significant temperature drop coupled with the 825qF drop presented by the cementitious fireproofing, it is reasonable to estimate that the unexposed side temperature will not exceed the limits of ASTM E 119 (250q plus ambient). Therefore, this protection configuration is considered 3-hour T rated.

In plant inspection has revealed the presence of minor cracking within the Thermo-Lag 330-1 material. This minor surface cracking (up to 1/8 wide) is acceptable based on the intumescent properties of the material. When exposed to fire the material intumescences and forms a char layer to allow the subliming characteristics to cool the underlying substrate. Industry testing has demonstrated 1/4 through holes were not specifically detrimental to the overall performance of the protective coating.

Exposed Thermo-Lag 330-1 and cementitious fireproofing providing hatch cover protection may be covered with a paint topcoat as necessary to protect against potential moisture intrusion. An acceptable topcoat is Thermo-Lag 311 (see Figure 3). This is the topcoat recommended for use by the Thermo-Lag vendor (Thermal Science Incorporated). Additionally, industry Thermo-Lag fire testing, in support of developing the NEI Thermo-Lag Application Guide, has demonstrated that topcoat products such as Thermo-Lag 311 have no net effect on the thermal performance capability of a Thermo-Lag fire barrier assembly. This topcoat does not present an increase to area combustible loading once cured.

M-663-00017A Page 8 of 13 Attachment D1 Revision W05 No fire testing directly correlates the use of the Thermo-Lag 311 product for topcoating cementitious fireproofing. However, considering the acceptable fire performance when coating an intumescent Thermo-Lag material, and the static nature of the cementitious material when exposed to fire, the topcoat also will not negatively impact the thermal performance of cementitious fireproofing.

5.2.2 Hatch Cover Plate Interface with Seismic Gap A seismic gap seal has been installed at the Containment wall and Auxiliary Building C Buttress hatch openings to maintain fire barrier continuity.

This seismic gap design is similar to that required by M-663-00017, typical detail SG-2. The installed seismic gap seal design at the hatchways differs slightly from the evaluated SG-2 typical detail, but is considered superior both structurally and from a fire resistant capability. This superiority is based on the bottom side, structural steel slip joint design installed between the Containment wall and the 1/4 steel checker plate hatch cover as shown in Figure 1. This steel slip joint provides substantial corbel support for the primary fire resistant sealant (ceramic fiber) and is installed to be compatible with building moments.

This steel is also protected with a cementitious fireproofing material to satisfy fire endurance requirements. Although the structural members sizes and configuration that make up the hatch support members are smaller than that fire tested, the considerable surface area contact with the underlying concrete provides significant value through heat transfer. Therefore, structural integrity is maintained as a result of thermal inertia and the insulating capability of the applied cementitious fireproofing clad.

The other differing element to the SG-2 typical detail is that no installed seismic Dymeric 511 caulk is provided on the bottom side of the seismic gap seal. The lack of bottom side Dymeric caulk has no impact to fire rating of the seal and is not a critical design attribute in the installed configuration based on the following, x The openings are not required to satisfy Water, Air or Pressure design requirements based on a review of adjacent penetration seals design requirements.

x At the hatchway locations the openings are constructed with a flood curb to satisfy any flood issues caused by fire fighting activities.

x The presence of cementitious fireproofing on the bottom side provides protection from water intrusion.

x There are no safety related, PFSSD components or equipment located in close proximity to the openings, if inadvertent water intrusion were to occur during fire fighting activities.

Based on the above discussions the C Buttress hatch interface with the seismic gap seal provides an equivalent 3-hour F and T rated configuration.

M-663-00017A Page 9 of 13 Attachment D1 Revision W05 5.2.3 Hatch Cover Plate Optional Protection and Configuration An optional configuration is herewith evaluated to partially eliminate the fireproofing material on one side of the C-Buttress enclosure (1/4 checker plate) that separates fire areas. The Bottom side protection will be revised to utilize 4 layers of Darmatt KM-1 panel secured to the 1/4 checker plate with four (4) 1/4 fasteners and stainless steel large (14 gauge min) washer restraining plate.

The reason to eliminate the fireproofing on the topside and revising the material type on the bottom side of the hatch is to allow unrestricted access to the C-Buttress tendon tensioning covers without loss of fireproofing material during disassembly. The elimination of the fireproofing on one side of the C-Buttress enclosure checker plate will not negatively impact the barrier to prevent the passage of flame or negate the barrier F and T rating. The design will be also prevent water flow to the lower level as previously designed.

Installation of 3-hour Darmatt KM-1 panel configuration on the bottom side of the enclosure plate, abutting snugly to the required structural steel fireproofing and slab opening sides will provide a 3-hour fire rating (F & T).

Both design requirements (fire and flood) are being met with the optional design. The new design will also permit the one-piece removal of the enclosure plate without damaging the fireproofing material, reducing cost consequences as compared to the current design. The structural components of the design are unchanged and fire resistance is the only change requiring evaluation and bounding.

The physical differences between the original design and the optional design being evaluated are as follows:

x The optional C-Buttress enclosure is not protected on one side (top or bottom).

x Reduced SG-2 seismic gap ceramic fiberfill (2 as compared to 3) throughout the Tendon Cover interference.

x Use of 3-Hour Darmatt KM-1 material design to protect the SG-2 design along the Containment Building interface and on side of the C-Buttress closure plate.

The design change at the 2047-6, South side C-Buttress enclosure will eliminate the need to cover the topside checker plate with fireproofing and changing the fireproofing material to Darmatt KM-1 along the side of the seismic gap configuration.

The hatch/C-Buttress enclosure plate shall be stenciled on top to ensure that material or combustibles are not stored on the enclosure plate and there are no combustibles within proximity to auto-ignite and propagate fire if a fire would occur in the fire area below. All four C-Buttress enclosures are similar and situated providing the same affect to combustibles. Therefore, this change may be applied to remaining C-Buttress enclosures when they are disassembled, provided the critical attributes evaluated are herein are incorporated.

M-663-00017A Page 10 of 13 Attachment D1 Revision W05 By installing the four (4) layers of Darmatt KM-1 on the bottom side of the checker plate maintains the F and T rating of the enclosure. The Darmatt KM-1 is fit snug to the slab opening and the structural fireproofing installed on the steel angle supports and fitted with intumescent expanding gasket material, closing off any plate exposure during fire exposure. The reduced ceramic fiberfill along the tendon cover interface (2 min) within the seismic gap seal design is compensated with 1 of additional fireproofing material on the support steel below to reduce thermal heat flux through the seismic gap seal design. In addition, Darmatt KM-1 as been added to the side of the seismic gap design and at the transition sections at each end of the closure plate to protect the vertical portions of the seismic gap design and transition segments from direct flame impingement. It must be noted that the seismic gap design at the C-Buttress does not incorporate Dymeric compound on the bottom side but incorporates a heavy steel support angle and fireproofing protection. Therefore, heat flux would have to propagate through approximately 2-1/2 of fireproofing and through the large 1/2 thick steel angle and the (2 min) ceramic fiberfill to affect the code side temperature. The remaining seismic gap configuration is as required and bounded per M-663-00017, Detail SG-2.

Four layers of Darmatt KM-1 has demonstrated through industry testing programs, to satisfy cold side temperatures when applied to cable tray, conduit and boxed enclosures. Installing the Darmatt KM-1 with steel or stainless steel fasteners and a large stainless steel restraining plate will ensure that the Darmatt KM-1 will remain fixed to the enclosure plate during fire and hose stream exposures resulting from firefighting activities. Typically Darmatt KM-1 barriers are secured with tie wire at 6 intervals along the barrier seams.

Because the cover plate protection is one piece that is restraining and covering the majority of the Darmatt KM-1 protective panels typical attachment methods will not be required. The Darmatt KM-1 panels covered by the restraining plate will perform at least equivalent to direct exposed Darmatt KM-1 panels. The large restraining plate will shield the underlying Darmatt KM-1 from direct flame impingement and equally spread the flame or hot gas throughout the exposed surface eliminating hot spots. Unlike similar fire protective barrier materials, Darmatt KM-1 does not require direct flame exposure to perform and insulate the underlying commodity during fire exposures. Darmatt KM-1 is not intumescent or subliming material. If necessary when consider reversing the Darmatt KM-1 to the top of the checker plate, notching the material at the fasteners is permissible. The small area notch is acceptable because the fastener will be recessed within the four layers and no combustible are permitted to be stored on the enclosure plate or with close proximity.

Water exposure during postulated flood conditions could expose some of the Darmatt KM-1 material to water. Industry Test, E-106-00031 performed a Soak and Drying test to ensure that repeater water exposures would not have a deleterious affect on the base material. The test sample was tested without the waterproof grey cloth to enable a worse case scenario by cyclic exposures with complete submersion. Post testing observations concluded that the material maintained its original physical conditions with no obvious degrading affects.

Based on the above discussions, the use of 3-hour Darmatt KM-1 material, either on top or the bottom of the enclosure plate, and on the vertical sides of

M-663-00017A Page 11 of 13 Attachment D1 Revision W05 the seismic gap design provides an equivalent 3-hour F and T rated configuration as originally designed.

5.3 Post Fire Safe Shutdown Impact There is no impact to PFSSD systems or components as a result of this evaluation.

The C Buttress hatch cover plates and associated interface with the seismic gap seal are evaluated as 3-hour F and T rated.

6.0 Conclusions Based on the above discussions, it is reasonable to conclude that the C Buttress hatch cover plates and associated interface with the seismic gap seal are 3-hour F and T rated. The C Buttress hatch covers with one sided Darmatt KM-1 fireproofing protection or two sided protection as originally designed satisfy regulatory requirements and commitments as well as WCNOC Fire Protection Program requirements, to prevent spread of fire from one Fire Area to another.

This evaluation was conducted in effort to satisfy regulatory expectation regarding qualification and documentation of fire barrier penetration seals, as discussed in NRC Information Notice 88-04. This evaluation was conducted in accordance with the guidance of NRC Generic Letter 86-10.

5.0 Evaluation 5.1 Assessment of Condition to Design Requirements The steel cover plate over penetration P141S1028, shown in Photos 1 and 2, is not directly bounded by a typical seal detail from M-663-00017. The plate protection was discussed in Revision 17 to USAR Section 9.5.1.2.2.3. However, additional discussion was deemed necessary in order to address the current,

M-663-00017A Page 5 of 6 Attachment D2 Revision W01 primary use of Room 1405. This room, which is on the topside of the floor penetration, is designated as a combustible material staging area per AP 10-102.

Photo1, P141S1028 Topside Photo 2, P141S1028 Bottom Side Room 1405 & Fire Area A-26 Room 1307 and Fire Area A-8 5.2 Evaluation of Condition The resin loading chute is located in the Auxiliary Building, 2026' elevation floor slab between Rooms 1405 and 1307. The chute is used to facilitate the loading of resin into the demineralizer compartments. The chute opening is integral with an embedded steel floor sleeve that is elevated approximately 4 above the floor surface. The opening is covered with a 1/4 thick steel plate. The steel plate design protecting the opening is depicted on drawing C-0C1441. The penetration opening is controlled via penetration number P141S1028.

The 1/4 thick steel plate protection ensures that that the opening portion protected by steel will not allow the passage of flame comparable to UL System CAJ0010. This UL system reveals that a minimum 0.057 (16 gauge) thick steel plate on one barrier side provides a 3-hour Fire (F) rated seal. The design of the steel cover plate reduces the likelihood for plate distortion as it overlaps the penetration sleeve and is not subject to any load other than that presented by the weight of the plate. The elevated embedded sleeve will also prevent water intrusion from manual fire fighting activities entering the fire area below. In addition, there are no safety related, PFSSD components or equipment located in close proximity to the openings if inadvertent water intrusion would occur during manual fire fighting activities.

There is no direct testing demonstrating a Temperature (T) rating for the steel plate. Therefore, further review is required to assess acceptability. Calculation XX-X-004 reveals that the combustible loading for the area below penetration P141S1028 is Low, while the topside combustible loading still maintains a Low classification, even with an allowance for storage of up to 1,000 lbs of Class A material.

The floor slab containing penetration P141S1028 is 20 thick reinforced concrete (Reference 3.6). This substantial barrier thickness ensures that a fire in Fire Area A-26 (topside of penetration) will not result in unacceptable unexposed side temperatures beyond the barrier plane, as the significant air gap (24) will dramatically drop temperature influence from the exposed side. This

M-663-00017A Page 6 of 6 Attachment D2 Revision W01 determination is based on the discussion provided in Section 7.2.3 of M-663-00017, which reveals a conservative linear temperature drop of 222qF for each inch of air space transition from the exposed element.

The recessed location of the plate from the bottom side provides some protection from direct flame impingement, as fire would need to travel up through the opening for a distance of 24 inches before reaching the plate. Since the opening will not promote a stack affect, flame transition into the barrier opening would be limited, especially considering the low combustible loading in the area.

The platform area below the penetration is not typically subjected to a significant transient combustible package, as it is within horizontal travel path of the resin loading chute. Additionally, fixed, exposed combustible loading in proximity to the opening is Low. Considering area combustibles and the recessed location of the plate, a fire in Fire Area A-8 will not will not present a potential ignition source, via steel plate conduction, for combustibles within Fire Area A-26.

Therefore, barrier integrity is ensured.

Based on the above discussion, the steel cover plate over penetration P141S1028 provides an acceptable level of fire protection commensurate with the hazards present in the area. The steel plate is considered 3-hour F rated.

Additionally, it is reasonable to conclude that the non-T rated aspect of the steel cover plate will not negatively impact a communicating Fire Area based on the combustible loading for a fire in Fire Area A-8 and the separation distance of the steel plate from the unexposed barrier side for a fire in Fire Area A-26.

5.3 Post Fire Safe Shutdown Impact There is no impact to PFSSD systems or components as a result of this evaluation. The steel cover plate for penetration P141S1028 provides a 3-hour F rated seal. The protection configuration and area hazards provide reasonable assurance that barrier integrity and PFSSD capability will not be compromised as a result of the non-T rated aspect of the penetration seal.

6.0 Conclusions Based on the above discussions, it is reasonable to conclude that the steel cover plate for penetration P141S1028 is acceptable as 3-hour F rated and will perform its intended function, regardless of not achieving a T rating. The penetration seal satisfies regulatory requirements and commitments as well as WCNOC Fire Protection Program requirements, to prevent spread of fire from one fire area to another. It has also been determined through this evaluation that the lack of a T rating will not affect the plants ability to achieve and maintain PFSSD.

M-663-00017A Page 5 of 7 Attachment F1 Revision W01 5.0 Evaluation 5.1 Assessment of Condition to Design Requirements Vertical fire dampers GKD0180 and GKD0182 communicate between the 2047-6 elevation of the Auxiliary Building Control Room AC and Filtration Unit A (Room 1512 and Fire Area A-22) and the Control Building Equipment Cabinet Area (Room 3605 and Fire Area C-27). Drawing M-1H1521 reveals that these fire dampers are located outside the fire barrier plane on the Auxiliary Building side (see Photos 1 and 2) in accordance with the installation details of drawing M-0H1905. This configuration is not bounded by UL-555, which qualifies the fire resistive performance of fire dampers within the plane of the barrier. This issue was generally addressed in the original Fire Protection Licensing Basis (Reference 3.3). However, further discussion was deemed necessary to formally assess the acceptability of this fire barrier protective configuration.

M-663-00017A Page 6 of 7 Attachment F1 Revision W01 5.2 Evaluation of Condition Fire rated dampers are typically mounted and positioned between barrier surfaces within the plane of the barrier to replicate as tested conditions, with the exception of two Control to Auxiliary Building fire dampers, GKD0180 and GKD0182. Fire dampers GKD0180 and GKD0182 are mounted within a heavy welded steel enclosure, seismically attached to the barrier surface with eight (8) 5/8 Hilti Kwik Bolt Type II anchors, as shown on Drawing M-0H1905. These damper enclosures are constructed from 1/2 thick welded steel with a welded closure plate of 10-gauge steel. The duct is welded directly to the enclosure plate and the enclosure plate welded to the damper assembly enclosure. The surface mounted enclosures are fabricated in a manner that integrates the support structure and damper assembly enclosures into single unit that is conservatively protected with a clad of cementitious fireproofing material to resist the affects of direct flame impingement during fire exposure. Structurally, the damper enclosures are designed to satisfy both seismic requirements and fire exposure.

In the unlikely event that the attached duct sections would be exposed to direct flame impingement, the exposed duct sections could potentially become deformed during fire exposure. However, it is not credible that the small sections of 8 diameter duct would induce loads significant enough to structurally degrade or deform the robustly constructed damper enclosures during a fire exposure.

Because damper tracks maintain a 1/4 expansion joint and are not physically attached to the enclosure, thermal expansion would not have a direct affect to the operation of the damper assembly. The cementitious fireproofing completely encapsulating the damper enclosure sides, support structure and associated anchors that attach the enclosure to the barrier surfaces add significant protection from the degrading affects of fire exposure. This protective configuration coupled with the significant heat sink capability of the barrier provides substantial protection from heat induced structural failures or significant deformation to the steel enclosure and fire damper assembly. Although the structural member sizes that make up the damper enclosures are smaller than that tested (Reference 3.10 and 3.11) with fireproofing protection, the considerable surface area contact with the underlying concrete provides significant value through heat transfer. Therefore, structural integrity is maintained as a result of thermal inertia and the insulating capability of the applied cementitious fireproofing clad.

Considering the robust damper enclosure design and the installed cementitious fireproof clad along with the heat transfer capability of the interfacing concrete wall, it is reasonable to conclude that a failure of the duct on either side of the wall will not violate the fire barrier or prevent the damper assembly from operating as designed.

M-663-00017A Page 7 of 7 Attachment F1 Revision W01 5.3 Post Fire Safe Shutdown Impact There is no impact to PFSSD systems or components as a result of this evaluation. Fire dampers GKD0180 and GKD0182 will prevent the passage of flame between communicating Fire Areas for a duration of 3-hours.

6.0 Conclusions Based on the above discussions, it is reasonable to conclude that fire dampers GKD0180 and GKD0182 provide 3-hour protection equivalent to a fire damper located within the barrier plane as tested by UL 555. The fire dampers satisfy regulatory requirements and commitments as well as WCNOC Fire Protection Program requirements, to prevent spread of fire from one Fire Area to another.

M-663-00017A Page 4 of 16 Attachment G1 Revision W03 1.0 Purpose 1.1 The purpose of this document is to evaluate generic fireproofing issues resulting from plant walk downs conducted in effort to address the acceptability of protected structural steel with unprotected miscellaneous steel attachments (thermal shorts) that are welded to the building steel. This evaluation was conducted in accordance with the guidance of NRC Generic Letter 86-10 and Regulatory Guide 1.189.

2.0 Scope 2.1 This evaluation is applicable to the Rooms identified in Table II.

3.0 References 3.1 NRC Generic Letter 86-10, Implementation of Fire Protection Requirements, dated April 24, 1986 3.2 10 CFR 50 Appendix R, Fire Protection Program For Nuclear Power Facilities Operating Prior To January 1, 1979 3.3 Regulatory Guide 1.189, Fire Protection For Operating Nuclear Power Plants, April 2001 3.4 ASTM E-119, Standard Test Methods for Fire Tests of Building Construction and Materials 3.5 UL N-711, (A-126-00001), Fire Test Report Of Loaded Restrained Beams Protected By Cementitious Mixture, Dated August 11, 1976 3.6 UL N-712, (A-126-00002), Fire Test Report Of Loaded Restrained Beams Protected By Cementitious Mixture, Dated May 13, 1977 3.7 A-126, Technical Specification For Cementitious Fireproofing Of Structural Steel For The Standardized Nuclear Unit Power Plant Unit (SNUPPS) 3.8 PIR 2002-2287, Structural Steel Fireproofing With Unprotected Attachments 3.9 FP-M-012, Rev 0, Structural Steel Fireproofing Thermal Shorts and Omissions Evaluation 3.10 CNT-MC-600, Rev. 2, Fireproofing of Structural Steel 3.11 Drawing A-1801, Rev. 10, Architectural Fire Delineation Floor Plan EL 1974-0 3.12 Updated Safety Analysis Report (USAR) Section 9.5.1.2.2.3.c, Rev. 15 and Table 9.5A-1 Sheet 27, Rev. 4

M-663-00017A Page 5 of 16 Attachment G1 Revision W03 4.0 Assumptions 4.1 It is assumed that fireproofing material used to protect building steel is applied to the thickness required by CNT-MC-600. This is an acceptable assumption based on a review of the Quality Control documentation maintained during initial fireproofing installation activities and subsequent inspections during ongoing plant repairs witnessed by Fire Protection personnel.

5.0 Assessment of Condition to Design Requirements 5.1 Requirements USAR Section 9.5.1.2.2.3.c , identifies that the notes contained on Figure 9.5.1-2

[Drawing A-1801] define the structural steel fireproofing requirements. The structural steel of all of the ceilings of the fire areas is fireproofed with 3-hour protection with the exception that no fireproofing is provided on the underside of the fuel building roof.

USAR Table 9.5A-1 Sheet 27 (Rev. 4), that structural steel supporting the Control and Auxiliary Building roofs is protected with [3-hour] rated fireproofing.

Table I identifies the ASTM E-119 temperature limitations for structural steel protected with fireproofing.

TABLE I ASTM E-119 Temperature Limitations for 3-Hour Fire Exposure Structural Member Maximum Single Point Maximum Average Type Temperature (qF) Temperature (qF)

Beam 1300q(F) 1100q(F)

Column 1200q(F) 1000q(F) 5.2 Assessment At Wolf Creek, fireproofing material is generally applied over exposed surfaces of structural members with the exception of thermal shorts and intervening items.

Underwriters Laboratories (UL) has tested several different size members utilizing both Albi Duraspray and Monokote Z-146 coatings to 3-hour ASTM E-119 fire exposures. The testing for beams and columns, utilized W8 x 28 steel shapes incorporating two protection methods; contour and boxed. However, testing of both techniques did not incorporate thermal short attachments.

Therefore, the affects of heat flux into plant structural steel with unprotected thermal shorts is not directly bounded by fire testing. FP-M-012 revealed that unprotected thermal shorts, larger than Unistrut, contribute to single point temperatures that in some cases exceed the ASTM E-119 acceptance criteria, assuming a 3-hour fire exposure. Typically, average temperatures satisfied the ASTM E-119 acceptance criteria.

M-663-00017A Page 6 of 16 Attachment G1 Revision W03 Additionally, in various plant areas structural steel has been integrated as part of the fire barrier assembly. However, fire testing does not directly bound the use of protected steel as an element of a fire barrier assembly.

For the purpose of this evaluation, all unprotected thermal shorts greater than Unistrut were reviewed and considered relevant to determine worse case scenario.

FP-M-012 demonstrated that thermal short attachments equivalent to Unistrut did not present a thermal conductive path that would challenge structural steel integrity, assuming an ASTM E-119 fire exposure.

See section 12.2.3 of M-663-00017A for further discussion regarding the overall fireproofing assessment methodology utilized.

Based on categorization of walkdown results, the following generic issues are addressed by this evaluation:

x Appendix R Barriers with Incorporated Structural Steel x Steel Internal to Cable Chases x Embedded Steel x Miscellaneous Steel x Steel Protection for Stairwells and Elevators x Diesel Building Structural Steel

M-663-00017A Page 11 of 16 Attachment G1 Revision W03 x Control Building Duct Chase Appendix G1A to this evaluation documents the result of the Fire Protection reviews and assessments for each room listed in Table II. The data sheets are provided to record input information critical to the overall assessment process. Where a room did not present a unique/unbounded structural steel fireproofing issue, the basis for acceptability is documented in the corresponding G1A walkdown data sheet, and is repeated in Table II.

7.0 Evaluation 7.1 Appendix R Barriers With Incorporated Structural Steel Two-sided protected steel integral to a fire barrier assembly is typically used where cable chases have been erected to separate fire areas. The steel is located at the ceiling and forms a part of the fire barrier interfacing with concrete or CMU walls and concrete ceilings completing the separation from other fire areas.

When integrated fire barrier structural or steel enclosures are protected with fireproofing material on both sides of the barrier, only one barrier side will be exposed to the fire, thus limiting heat flux through the unexposed fireproofing.

The unexposed fireproofing can be expected to provide a significant insulator as demonstrated by comparing the delta between furnace temperature and the maximum steel exposure temperature.

Where two-sided cementitious fireproofing is provided the protected steel is expected to meet WCNOC cold side temperatures requirements. This expectation is based on the following:

x During ASTM E-119 testing, furnace temperatures are maintained at 1925qF. By subtracting the furnace temperature (1,925qF) from actual thermocouple data (1,100qF) from References 3.5 and 3.6 yields an approximate 825qF temperature drop across the exposed fireproofing during ASTM E-119 fire endurance testing. By applying this temperature drop logic to the unexposed fireproofing, similar results will be achieved, yielding an expected temperature of approximately 275qF to the unexposed side of the barrier. This estimated 275qF is below the maximum cold side temperature limitations required by the WCNOC Fire Protection Program (250qF plus ambient for fire barrier construction and 325qF plus ambient for fire barrier penetration seals). Therefore, two sided protection configurations are considered 3-hour F and T rated, provided no unprotected thermal shorts greater than Unistrut in size or mass are present. Calculation FP-M-012 has demonstrated that unprotected Unistrut has no significant thermal influence to building steel under fire exposure conditions.

Where thermal shorts greater than Unistrut in size/mass are present, each location on the steel portion of the barrier was reviewed for Heat Affected Zone (HAZ) influence to ensure Post Fire Safe Shutdown (PFSSD) is not impacted or

M-663-00017A Page 12 of 16 Attachment G1 Revision W03 insitu combustibles are not in proximity to allow auto ignition resulting in flame propagation. The HAZ review is documented in Attachment G5.

Cable chase fire barriers are typically constructed with reinforced concrete and/or solid CMU walls and steel at the ceiling interface that forms a part of the Appendix R barrier. This integrated barrier design incorporates an approximate 1 gap for seismic interaction that is filled full depth with compressed ceramic fiber and is coated on both sides with structural steel fireproofing. The concrete or CMU walls do not directly support the steel due to the approximate 1 gap between the bottom flange of the steel member(s) and the top of the barrier wall(s). The presence of the gap will not be a detriment or have a degrading affect to the barrier since the gap is completely filled with ceramic fiber and clad with cementitious fireproofing material on both sides of the barrier. The wall segments that make up the barrier portions of the wall and/or fire barrier will prevent catastrophic steel failure by supporting the steel from below if steel deflection occurs during fire exposures. However, because steel sizes are so much greater than that tested (W8 X 28), steel deflection is not expected to occur and barrier integrity will be maintained for a 3-hour duration. Additionally, transient combustible presence with the cable chases is limited and access is strictly controlled, with cable chase doors remaining locked during normal plant operation and/or refuel evolutions. Moreover, cable chases are provided with detection and a wet pipe sprinkler system (C-36 and C-37 are provided with sprinkler protection only) to rapidly suppress any fire that may occur, providing direct cooling to the steel portions of the barrier. Therefore, it is reasonable to conclude that barrier failure will not occur due to unsupported steel forming a part of the cable chase walls.

7.2 Steel Internal to Cable Chases Several of the larger cable chases were found to contain smaller steel (typically W12 X 28) with moderately sized unprotected tube members attached. These smaller structural members have been provided for cable tray support designs not to support the building slab or equipment above. The larger perimeter steel of these cable chases is the primary support structure for the slab and associated building structures, which provides the required structural integrity. When comparing the other areas adjacent to the cable chases the slab thickness is the same, with significantly greater spans between main structural steel members within the adjacent rooms reviewed. Because cable chase room spans are minimal and the cable tray supports are from floor to ceiling, where they are attached to the smaller structural steel members, it is not credible that failure would occur from the affects of fire.

Based on the above discussions, it is reasonable to conclude that these rooms and/or areas are acceptable and will not require a detailed thermal short analysis for the reasons discussed above.

7.3 Embedded Steel Building steel that is partially embedded into concrete slabs (ceilings) is not subject to failure by unprotected thermal shorts. The concrete slabs provide substantial reinforcement and significant heat sink capability to the embedded

M-663-00017A Page 13 of 16 Attachment G1 Revision W03 steel. Therefore, it is not credible to postulate steel failure due to unprotected thermal short attachments when steel is embedded into reinforced concrete.

Building steel that is partially embedded or integrated to concrete walls forming a fire barrier is designed with concrete (6 thick, min) on one side and protected with fireproofing on the other side. This design also presents direct support to the steel from below and side. Thus, providing substantial reinforcement and significant heat sink capability to the structural steel if exposed to direct flame impingement. Therefore, it is not credible to postulate steel failure due to unprotected thermal short attachments when steel is embedded into reinforced concrete walls and supported from below.

7.4 Miscellaneous Steel In some case miscellaneous steel was protected with fireproofing material.

Failure of miscellaneous steel will not result in room/area building steel failure.

Therefore, further review is not required. Degraded fireproofing on miscellaneous steel does not require repair.

7.5 Steel Protection for Stairwells and Elevators Stairwell and elevator steel integral to the fire barrier assembly is only protected on the hazard side in accordance with Specification A-126 (Reference 3.7).

Since the fire loading in the stairwells and elevator enclosure(s) are extremely low, a credible fire cannot occur or challenge the building steel integrated to stairwell or elevator barriers. Stairwell and elevator barriers are typically constructed with reinforced concrete and/or solid CMU walls and steel at the ceiling interface that forms a part of the Appendix R barrier. This integrated barrier design incorporates an approximate 1 gap for seismic interaction that is filled full depth with compressed ceramic fiber and is coated on the hazard side with structural steel fireproofing. The concrete or CMU walls do not directly support the steel due to the approximate 1 gap between the bottom flange of the steel member(s) and the top of the barrier wall(s). The presence of the gap will not be a detriment or have a degrading affect to the barrier since the gap is completely filled with ceramic fiber and clad with cementitious fireproofing material on the hazard side of the barrier. The wall segments that make up the barrier portions of the wall and/or fire barrier will prevent catastrophic steel failure by supporting the steel from below if steel deflection occurs during fire exposures. However, because steel sizes are so much greater than that tested (W8 X 28), steel deflection is not expected to occur and barrier integrity will be maintained for a 3-hour duration. Additionally, storage of transient combustibles within stairwells is not generally permitted due to egress and ingress requirements. The design of the elevator enclosure does not permit access or storage of combustible materials.

These one sided structural steel fireproofing configurations are determined to be F rated only and cannot satisfy T rating requirements if exposed to an ASTM E-119 3-hour fire duration. Specification A-126, section 7.1 states in part, stair towers and elevator construction shall be protected from external hazards.

Therefore, in these cases structural steel fireproofing is not required on both sides of the barrier. Where these barriers provide Appendix R separation, this

M-663-00017A Page 14 of 16 Attachment G1 Revision W03 configuration does not satisfy cold side temperature limitations of the WCNOC Fire Protection Program. Therefore, for each location where one-sided fireproofing or significant attachments are present the area was reviewed for Heat Affected Zone (HAZ) influence to ensure PFSSD is not affected. This HAZ review is documented in Attachment G5. Thermal shorts attached to stairwell steel will not impact the structural integrity of the steel due to the corbel support afforded by the under supporting walls.

7.6 Diesel Building Structural Steel The Diesel Building rooms 5201 and 5203 were reviewed for unprotected thermal short impact to fireproofed structural steel. However a worse case thermal short analysis review was not warranted. This is due to the fact that building steel for room 5201 is not directly connected to room 5203 building steel. If failure would occur in one room it will not influence the redundant room building steel. The center reinforced concrete wall is two feet thick which supports both steel structures in both Diesel rooms through large embeds. Because of the robust nature of the wall, it will remain unaffected by fire, thus preventing catastrophic structural failure. Industry testing for penetration seal and fire wrap has repeatedly demonstrated that concrete test slabs with substantially less thickness and grade of concrete were not affected to the point of failure for a 3-hour duration. Although, these test slabs were not load bearing, no evidence of heat stress occurred, further substantiating the integrity of the separation wall between the two fire areas for the emergency diesel generators.

Based on the above discussion it is reasonable to conclude that steel failure caused by fire in one diesel generator room will not affect the redundant train room or PFSSD capability. Therefore further thermal short analysis is not required.

7.7 Control Building Duct Chase The Control Building Duct Chase (Fire Area C-1) is open to all levels of the Control Building, traversing up from 1974 elevation Room 3101 to the 2073 elevation interfacing with multiple Fire Areas. See Figure I for a simplified elevation view of the duct chase in relation to interface with other Control Building fire areas. Fire Protection has performed a visual inspection of the integrated barrier steel fireproofing as observed from the Control Building 1974 (Room 3101) elevation, and has determined that the Duct Chase steel is protected on the chase side as well as room sides (two-sided protection) throughout the Control Building. This visual inspection noted four (4) levels without difficulty and the remaining floors and associated steel could not be observed due to accessibility limitations presented by HVAC duct and support steel. However, based on that observed from 1974 (4 levels), it is reasonable to conclude that the remaining integrated steel members that make up the duct chase are protected with fireproofing consistent with the observed lower levels. Therefore, protected duct chase steel that is integral to an Appendix R fire barrier will perform consistent with that discussed in Section 7.1. A HAZ review is not required on the Duct Chase side since the opening is limited to mechanical components. Attachment G5 documents the HAZ review for the Control Building rooms interfacing with the duct chase.

M-663-00017A Page 15 of 16 Attachment G1 Revision W03 FIGURE I Control Building Duct Chase 8.0 Post Fire Safe Shutdown Impact Table II rooms with no exposed steel, no thermal short attachments, or worse case thermal short attachments equivalent to Unistrut, do not negatively affect post-fire safe shutdown (PFSSD) from a building structural integrity perspective, as the failure mode of concern (significant thermal insult path to structural steel) is not present.

For the remaining Table II rooms (with the exception Rooms 5201 and 5203), PFSSD is not negatively affected from a building structural integrity perspective as the evaluations above determined that room/fire area structural integrity would be maintained in the event of an ASTM E-119 3-hour fire exposure.

For Rooms 5201 and 5203 the unique or unbounded structural steel fireproofing configurations are acceptable, as fire barrier separation is maintained with no impact to PFSSD capability.

M-663-00017A Page 16 of 16 Attachment G1 Revision W03 Refer to Attachment G5 for documentation of the HAZ review for steel that is incorporated as an element of an Appendix R fire barrier assembly.

9.0 Conclusions Based on physical plant walk down reviews and assessments performed by Fire Protection, the rooms identified in Table II, containing protected structural steel (where applicable) have been determined to be acceptable due to steel configurations and/or supporting wall structures that ensure fire barrier separation will be maintained in the event of an ASTM E-119 3-hour fire exposure. Some rooms did not contain structural steel, and some steel structures had no thermal attachments and are bounded to UL testing. Others contained worse case thermal short attachments equivalent to Unistrut, which FP-M-012 demonstrated did not present a thermal conductive path failure mode for protected structural steel.

In conclusion, Table II rooms containing structural steel protected with fireproofing are acceptable, as fire barrier separation is maintained with no impact to PFSSD capability.

This is an acceptable assumption based on a review of the Quality Control documentation maintained during initial fireproofing installation activities and subsequent inspections during ongoing plant repairs witnessed by Fire Protection personnel.

5.0 Assessment of Condition to Design Requirements 5.1 Requirements USAR Section 9.5.1.2.2.3.c , identifies that the notes contained on Figure 9.5.1-2

[Drawing A-1801] define the structural steel fireproofing requirements. The structural steel of all of the ceilings of the fire areas is fireproofed with 3-hour protection with the exception that no fireproofing is provided on the underside of the fuel building roof.

USAR Table 9.5A-1 Sheet 27 (Rev. 4), that structural steel supporting the Control and Auxiliary Building roofs is protected with [3-hour] rated fireproofing.

Table I identifies the ASTM E-119 temperature limitations for structural steel protected with fireproofing.

Column 1200q(F) 1000q(F) 5.2 Assessment At Wolf Creek, fireproofing material is generally applied over exposed surfaces of structural members with the exception of thermal shorts and intervening items.

Underwriters Laboratories (UL) has tested several different size members utilizing both Albi Duraspray and Monokote Z-146 coatings to 3-hour ASTM E-119 fire exposures. The testing for beams and columns, utilized W8 x 28 steel shapes incorporating two protection methods; contour and boxed. However, testing of both techniques did not incorporate thermal short attachments.

Therefore, the affect of heat flux into plant structural steel with unprotected thermal shorts is not directly bounded by fire testing. FP-M-012 revealed that unprotected thermal shorts, larger than Unistrut, contribute to single point

M-663-00017A Page 6 of 11 Attachment G2 Revision W03 temperatures that in some cases exceed the ASTM E-119 acceptance criteria, assuming a 3-hour fire exposure. Typically, average temperatures satisfied the ASTM E-119 acceptance criteria.

It should be noted that W shapes thermally perform significantly better than H shapes due to the larger exposed area of the H shape.
2. Hot spot forms in Web area around thermal short. Structural considerations could show this element performs its intended design function for three-hours. This Note is a direct excerpt from Calculation FP-M-012.
3. Refer to Attachment G5 for the Heat Affected Zone (HAZ) review where steel is an integral element of the fire barrier assembly

M-663-00017A Page 8 of 11 Attachment G2 Revision W03 6.0 Methodology As discussed in Section 12.2.2 of M-663-00017A, Section 4.2.2 of Regulatory Guide 1.189 identifies that structural steel is not required to be protected to the fire resistance rating of the barrier [typically 3-hours], provided analysis demonstrates that the steel temperature reached during fire exposure does not result in structural failure of the steel.

Considering the results of FP-M-012, where an ASTM E-119 3-hour fire was modeled to assess thermal insult presented by unprotected attachments connected to protected steel, the Reg. Guide 1.189 approach allowance is utilized to address impact of unprotected thermal short attachments larger than Unistrut.

Walkdowns were conducted on a room-by-room basis utilizing structural steel drawings and a best effort visual inspection to determine the worse case thermal short configuration for columns, beams and where structural steel serves as an Appendix R fire boundary. For the purpose of this evaluation, all unprotected thermal shorts greater than Unistrut were reviewed and considered relevant to determine worse case scenario.

FP-M-012 demonstrated that thermal short attachments equivalent to Unistrut did not present a thermal conductive path that would challenge structural steel integrity, assuming an ASTM E-119 fire exposure.

See section 12.2.3 of M-663-00017A for further discussion regarding the overall fireproofing assessment methodology utilized in the identification process for selecting the worse case thermal short configuration.

Each worse case thermal short configuration was then compared to the configurations identified in Table III, from FP-M-012, which were modeled assuming an ASTM E-119 3-hour fire exposure. The fire resistance rating of the Table III configuration that provided the closest match to the worse case configuration was utilized to infer an approximate fire resistance rating, again assuming an ASTM E-119 3-hour fire exposure.

This comparison information is captured in Table II. In all cases the structural steel for the rooms satisfied at least a 1-hour rating, and in several cases nearly a 3-hour rating.

Additionally, many unprotected attachment members were smaller than that analyzed in FP-M-012, and therefore the beam or column being evaluated is expected to perform better than that indicated.

In effort to assess structural steel performance considering representative plant configurations and hazards, the NUREG-1805 Fire Dynamics Tools (FDT) were utilized to determine the maximum hot gas layer temperature anticipated within the rooms considering bounding simple fire heat release rates provided in Appendix F of NRC Inspection Manual 0609.

7.0 Evaluation Each Room identified in Table II was reviewed and evaluated to determine if building structural members with unprotected steel attachments larger than Unistrut would affect the steel integrity in the event of fire. It was determined by utilizing NUREG-1805 Fire Dynamics Tools that these rooms would not develop a hot gas layer that would influence the existing building steel, and existing building steel protection configurations are acceptable to maintain building integrity.

Each room listed in Table II interfaces with one or more rooms through significant openings such as passageways, corridors, etc. that provide considerable venting and cooling capability. Considering that the open room configuration effectively presents a natural ventilation arrangement for each room, NUREG-1805 FDT 02.1_Temperature_NV.xls (Version 1805.1), was utilized to assess room hot gas layer temperature development. An example of the FDT is provided in Appendix G2A. This FDT is a method developed, prepared, and validated by the Nuclear Regulatory Commission (NRC) to allow a consistent, simplified approach to calculate developing gas layers within open rooms.

M-663-00017A Page 10 of 11 Attachment G2 Revision W03 Data collection necessary for FDT input is provided in the individual room data sheets documented in Appendix G2B. Input information necessary for the FDT is as follows:

x Compartment width (ft) x Compartment length (ft) x Compartment height (ft) x Barrier type (concrete or concrete block) x Barrier thickness (in) x Vent width (ft) x Vent height (ft) x Top of vent from floor (ft) x Ambient air temperature (qF) x Fire Heat Release Rate (kW)

In some situations, rooms contained multiple vents or openings to other areas. In these instances, only one vent or opening was used as input into the FDT to achieve a level of conservatism. A fire with a constant 650 kW heat release rate (HRR) was utilized for the Table II rooms. This HRR was chosen considering the guidance of Appendix F to NRC Inspection Manual 0609. Table IV, extracted from the Inspection Manual, reveals that a 650 kW HRR is based on a large electrical fire that reflects a high confidence limit (98th percentile) fire severity. This fire severity envelops large electrical fires, transient combustible fires, and 90% of very large fire sources. Although, the majority of the rooms evaluated in Table II would not likely produce a fire severity equivalent to 650 kW, the conservative fire intensity input ensures a bounding credible fire was utilized for the rooms of concern, without necessitating a detailed quantitative review of room contents.

In all cases, specific room area input into the FDT yielded hot gas layer results at a 180-minute duration that were less than the ASTM E-119 average temperature limitations identified in Table I. Refer, to the Appendix G2B room data sheets for specific results. The FDT results demonstrate that the natural venting provided for the open rooms is the primary contributor to the lower temperatures reflected through the FDT modeling process.

During ASTM E-119 fire testing, temperatures are recorded on the steel surface underneath the fireproofing protective coating in effort to assess fireproofing effectiveness when subjected to approximate 1925 qF fire exposure for a 3-hour duration. Considering that the FDT calculated room hot gas layer temperature was less than the Table I ASTM E-119 average temperature limitations, it is reasonable to conclude that unprotected thermal short attachments will not present a thermal failure mode to the structural steel, since the room will not attain temperatures during the postulated fire event that would challenge steel structural integrity.

8.0 Post Fire Safe Shutdown Impact There is no impact to post-fire safe shutdown (PFSSD) capability, as the evaluation demonstrates that postulated fire event room temperate will not result in detrimental impact to structural steel integrity.

Refer to Attachment G5 for the Heat Affected Zone (HAZ) review where steel is an integral element of the fire barrier assembly.

9.0 Conclusions This evaluation demonstrates that unprotected thermal shorts, attached to structural steel within the Table II rooms, does not result in a detrimental impact to structural steel integrity. Utilization of NUREG-1805 FDTs revealed that hot gas layer temperatures for each of the Table II rooms did not exceed the ASTM E-119 maximum average exposure temperature for beam or column limitation in the associated room. Therefore, the protected structural steel configurations within these rooms are acceptable for the intended service, and will not degrade the affected fire barrier or structural integrity of the building steel, or affect redundant PFSSD capability.

Based on the above discussion, it is reasonable to conclude that the existing fireproofing on the structural steel with unprotected attachments will satisfy regulatory expectations and commitments as well as WCNOC Fire Protection Program requirements, to prevent building steel failure as a result of fire exposure.

Where z = smoke layer height (m)

Q = heat release rate of the fire (kW) t = time after ignition (sec) hc = compartment height (m) 2 Ac = compartment floor area (m )

k = a constant given by k = 0.076/Ug 3

Ug = hot gas layer density (kg/m )

Ugis given by Ug = 353/Tg Tg = hot gas layer temperature (K)

The smoke layer height is a conservative estimate and is only intended to provide an indication where the hot gas layer is located. Calculated smoke layer height below the vent height are not creditable since the calculation is not accounting for the smoke exiting the vent.

This is an acceptable assumption based on a review of the Quality Control documentation maintained during initial fireproofing installation activities and subsequent inspections during ongoing plant repairs witnessed by Fire Protection personnel.

5.0 Assessment of Condition to Design Requirements 5.1 Requirements USAR Section 9.5.1.2.2.3.c , identifies that the notes contained on Figure 9.5.1-2

[Drawing A-1801] define the structural steel fireproofing requirements. The structural steel of all of the ceilings of the fire areas is fireproofed with 3-hour protection with the exception that no fireproofing is provided on the underside of the fuel building roof.

USAR Table 9.5A-1 Sheet 27 (Rev. 4), that structural steel supporting the Control and Auxiliary Building roofs is protected with [3-hour] rated fireproofing.

Table I identifies the ASTM E-119 temperature limitations for structural steel protected with fireproofing.

TABLE I ASTM E-119 Temperature Limitations for 3-Hour Fire Exposure Structural Member Maximum Single Point Maximum Average Type Temperature (qF) Temperature (qF)

Beam 1300q(F) 1100q(F)

Column 1200q(F) 1000q(F) 5.2 Assessment At Wolf Creek, fireproofing material is generally applied over exposed surfaces of structural members with the exception of thermal shorts and intervening items.

Underwriters Laboratories (UL) has tested several different size members utilizing both Albi Duraspray and Monokote Z-146 coatings to 3-hour ASTM E-119 fire exposures. The testing for beams and columns, utilized W8 x 28 steel shapes incorporating two protection methods; contour and boxed. However, testing of both techniques did not incorporate thermal short attachments.

Therefore, the affect of heat flux into plant structural steel with unprotected thermal shorts is not directly bounded by fire testing. FP-M-012 revealed that unprotected thermal shorts, larger than Unistrut, contribute to single point

M-663-00017A Page 6 of 13 Attachment G3 Revision W03 temperatures that in some cases exceed the ASTM E-119 acceptance criteria, assuming a 3-hour fire exposure. Typically, average temperatures satisfied the ASTM E-119 acceptance criteria.

1. Category 1 (H member) as been conservatively assigned to this beam attachment configuration due to the lack of analysis of a W shape configuration welded to the bottom beam flange. It should be noted that W shapes thermally perform significantly better than H shapes due to the larger exposed area of the H shape.
2. Hot spot forms in Web area around thermal short. Structural considerations could show this element performs its intended design function for three-hours. This Note is a direct excerpt from Calculation FP-M-012.
3. Refer to Attachment G5 for the Heat Affected Zone (HAZ) review where steel is an integral element of the fire barrier assembly.

6.0 Methodology As discussed in Section 12.2.2 of M-663-00017A, Section 4.2.2 of Regulatory Guide 1.189 identifies that structural steel is not required to be protected to the fire resistance rating of the barrier [typically 3-hours], provided analysis demonstrates that the steel temperature reached during fire exposure does not result in structural failure of the steel.

Considering the results of FP-M-012, where an ASTM E-119 3-hour fire was modeled to assess thermal insult presented by unprotected attachments connected to protected steel, the Reg. Guide 1.189 approach allowance is utilized to address impact of unprotected thermal short attachments larger than Unistrut.

Walkdowns were conducted on a room-by-room basis utilizing structural steel drawings and a best effort visual inspection to determine the worse case thermal short configuration for columns, beams and where structural steel serves as an Appendix R fire boundary. For the purpose of this evaluation, all unprotected thermal shorts greater than Unistrut were reviewed and considered relevant to determine worse case scenario.

FP-M-012 demonstrated that thermal short attachments equivalent to Unistrut did not present a thermal conductive path that would challenge structural steel integrity, assuming an ASTM E-119 fire exposure.

See section 12.2.3 of M-663-00017A for further discussion regarding the overall fireproofing assessment methodology utilized in the identification process for selecting the worse case thermal short configuration.

M-663-00017A Page 9 of 13 Attachment G3 Revision W03 Each worse case thermal short configuration was then compared to the configurations identified in Table III, from FP-M-012, which were modeled assuming an ASTM E-119 3-hour fire exposure. The fire resistance rating of the Table III configuration that provided the closest match to the worse case configuration was utilized to infer an approximate fire resistance rating, again assuming an ASTM E-119 3-hour fire exposure.

This comparison information is captured in Table II. In all cases the structural steel for the rooms satisfied at least a 1-hour rating, and in several cases nearly a 3-hour rating.

Additionally, many unprotected attachment members were smaller than that analyzed in FP-M-012, and therefore the beam or column being evaluated is expected to perform better than that indicated.

In effort to assess structural steel performance considering representative plant configurations and hazards, the NUREG-1805 Fire Dynamics Tools (FDT) were utilized to determine the maximum hot gas layer temperature anticipated within the rooms considering bounding simple fire heat release rates provided in Appendix F of NRC Inspection Manual 0609.

M-663-00017A Page 10 of 13 Attachment G3 Revision W03 7.0 Evaluation Each Room identified in Table II was reviewed and evaluated to determine if building structural members with unprotected steel attachments larger than Unistrut would affect the steel integrity in the event of fire. It was determined by utilizing NUREG-1805 Fire Dynamics Tools that these rooms would not develop a hot gas layer that would influence the existing building steel, and existing building steel protection configurations are acceptable to maintain building integrity.

Each Table II room is either a closed room with no ventilation or a closed room with forced ventilation. A closed room with no ventilation is consistent with the application of NUREG-1805 FDT 02.3_temperature_cc_rev1.xls (Version 1805.1), as it addresses modeling closed compartments with natural ventilation associated only with compartment leakage. This is an acceptable approach, as rooms of concern will have limited natural ventilation leakage occurring predominantly around allowed door gaps.

Therefore, this FDT was utilized to assess room hot gas layer temperature development for closed rooms containing no ventilation. An example of the FDT is provided in Appendix G3A.

Where rooms were closed, with the exception of forced air ventilation openings, it was recognized that these rooms would effectively become a closed room once HVAC fire damper closure was achieved. HVAC fire dampers are closed by one of the following means:

x Automatically close by the fire alarm system, following smoke detection activation, for dampers provided with an electro-thermal link (ETL).

x Close by the melting of a fusible link with a temperature rating of 165 qF.

Rooms with ETL controlled fire dampers were considered closed rooms with no forced ventilation, since room forced ventilation flow would be eliminated by fire alarm system activation, which would occur early in the fire development stage. Therefore, closed rooms with forced ventilation controlled by ETL fire dampers also utilize NUREG-1805 FDT 02.3_temperature_cc_rev1.xls (Version 1805.1).

Where fusible link fire dampers provide room ventilation isolation, it was recognized that forced ventilation would continue for the room until the compartment temperature reached the activation point of the fire damper fusible link. Therefore, each of these rooms was first treated as compartment with forced ventilation until room hot gas layer temperature exceeded 200qF. NUREG-1805 FDT 02.2_Temperature_FV.xls (Version 1805.0), was utilized for this application. An example of the FDT is provided in Appendix G3B. At the point that the hot gas layer temperature exceeded 200 qF, effectively creating a closed room with no ventilation following fire damper closure, relevant data from the Closed Room - Forced Ventilation FDT was extracted and utilized as input within the previously discussed FDT, for a closed room with no forced ventilation.

Data collection necessary for FDT input is provided in the individual room data sheets documented in Appendices G3C and G3D. Appendix G3C contains data for closed rooms with no ventilation, while G3D is for closed rooms with forced ventilation. Input information necessary for each FDT utilized is as follows:

M-663-00017A Page 11 of 13 Attachment G3 Revision W03 Closed Room - No Ventilation NUREG -1805 FDT 02.3_temperature_cc_rev1.xls (Version 1805.1) x Compartment width (ft) x Compartment length (ft) x Compartment height (ft) x Barrier type (concrete or concrete block) x Barrier thickness (in) x Ambient air temperature (qF) x Fire Heat Release Rate (kW) x Time when Closed Room - Forced Ventilation FDT exceeds 200qF (min)

  • x Compartment starting temperature for Closed Room - No Ventilation FDT (qF) *
  • Data input from Closed Room - Forced Ventilation FDT Closed Room - Forced Ventilation NUREG-1805 FDT 02.2_Temperature_FV.xls (Version 1805.0) x Compartment width (ft) x Compartment length (ft) x Compartment height (ft) x Barrier type (concrete or concrete block) x Barrier thickness (in) x Forced Ventilation Rate (cfm) x Ambient air temperature (qF) x Fire Heat Release Rate (kW)

A fire with a constant 650 kW heat release rate (HRR) was utilized for the Table II rooms. This HRR was chosen considering the guidance of Appendix F to NRC Inspection Manual 0609. Table IV, extracted from the Inspection Manual, reveals that a 650 kW HRR is based on a large electrical fire that reflects a high confidence limit (98th percentile) fire severity. This fire severity envelops large electrical fires, transient combustible fires, and 90% of very large fire sources. Although, the majority of the rooms evaluated in Table II would not likely produce a fire severity equivalent to 650 kW, the conservative fire intensity input ensures a bounding credible fire was utilized for the rooms of concern, without necessitating a detailed quantitative review of room contents.

In all cases, specific room area input into the FDT yielded hot gas layer results at a 180-minute duration that were less than the ASTM E-119 average temperature limitations identified in Table I. Refer, to the Appendix G3C and G3D room data sheets for specific results. The FDT results demonstrate that the lack of ventilation for the closed rooms is the primary contributor to the lower temperatures reflected through the FDT modeling process.

During ASTM E-119 fire testing, temperatures are recorded on the steel surface underneath the fireproofing protective coating in effort to assess fireproofing

M-663-00017A Page 12 of 13 Attachment G3 Revision W03 effectiveness when subjected to approximate 1925 qF fire exposure for a 3-hour duration. Considering that the FDT calculated room hot gas layer temperature was less than the Table I ASTM E-119 average temperature limitations, it is reasonable to conclude that unprotected thermal short attachments will not present a thermal failure mode to the structural steel, since the room will not attain temperatures during the postulated fire event that would challenge steel structural integrity.

8.0 Post Fire Safe Shutdown Impact There is no impact to post-fire safe shutdown (PFSSD) capability, as the evaluation demonstrates that postulated fire event room temperate will not result in detrimental impact to structural steel integrity.

Refer to Attachment G5 for the Heat Affected Zone (HAZ) review where steel is an integral element of the fire barrier assembly.

M-663-00017A Page 13 of 13 Attachment G3 Revision W03 9.0 Conclusions This evaluation demonstrates that unprotected thermal shorts, attached to structural steel within the Table II rooms, does not result in a detrimental impact to structural steel integrity. Utilization of NUREG-1805 FDTs revealed that hot gas layer temperatures for each of the Table II rooms did not exceed the ASTM E-119 maximum average exposure temperature for beam or column limitation in the associated room. Therefore, the protected structural steel configurations within these rooms are acceptable for the intended service, and will not degrade the affected fire barrier or structural integrity of the building steel, or affect redundant PFSSD capability.

Based on the above discussion, it is reasonable to conclude that the existing fireproofing on the structural steel with unprotected attachments will satisfy regulatory expectations and commitments as well as WCNOC Fire Protection Program requirements, to prevent building steel failure as a result of fire exposure.
