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.

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

Refer to Attachment G5 for the Heat Affected Zone (HAZ) review where steel is an integral element of the fire barrier assembly
M-663-00017 A Attachment G2 Revision W03 6.0 Methodology Page 8 of 11 As discussed in Section 12.2.2 of M-663-00017 A, 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 Ill, from FP-M-012, which were modeled assuming an ASTM E-119 3-hour fire exposure.
The fire resistance rating of the Table Ill 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-663-000 17 A Attachment G2 Revision W03 Page 10 of 11 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:
Compartment width (ft)
Compartment length (ft)
Compartment height (ft)
Barrier type (concrete or concrete block)
Barrier thickness (in)
Vent width (ft)
Vent height (ft)
Top of vent from floor (ft)
Ambient air temperature (°F)
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 (981h 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 °F 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 Conclusio.ns This evaluation demonstrates that unprotected thermal shorts. attached to structural steel within the Table II rooms.* does not result 1in a detrimental impact to structura1 steel integrity. Utilization of NUREG-1805 FDTs revealed that hot gas layer temperatures for each of the Table II rooms dld 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 fhe building steel, or affect redundant PFSSO 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.
