* Steel is provided with fireproofing on only one barrier side.
* Fireproofing is provided on both steel sides and an unprotected thermal short attachment larger than Unistrut is present.
This evaluation was conducted in accordance with the guidance of NRC Generic Letter 86-10.
2.0    Scope 2.1   This evaluation is applicable to the Rooms identified in Table II.

M-663-00017 A                                                                       Page 5 of 15 Attachment G5 Revision W03 3.13  Change Package 012323, M-663-00017A Revision to incorporate Structural Steel Fireproofing Evaluation and Analysis, Rev. 0 3.14  IEEE 383, Standard for Qualifying Class 1E Electric Cables and Field Splices for Nuclear Power Generating Stations 4.0    Assumptions 4.1   It is assumed that fireproofing material used to protect building steel is applied to a thickness as 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 and inspections performed during the this evaluation process.
5.0    Assessment of Condition to Design Requirements 5.1    Requirements USAR Section 9.5.1.2.2.3.a identifies that the design, construction, test method, and acceptance criteria for fire rated barriers is per applicable sections (determined by construction type) of ASTM E-119, UL standards, and state building codes.
5.2    Assessment Fire testing does not directly bound the use of protected steel as part of a fire barrier assembly. Such a configuration presents the potential to transmit detrimental temperatures from the fire side through the steel element of the fire barrier to insitu combustibles and/or post-fire safe shutdown (PFSSD) circuits located in close proximity to the unexposed side of the steel fire barrier segment.
Attachment G 1, Section 7.1, evaluated that steel with fireproofing on both barrier sides containing unprotected thermal short attachments no larger than Unistrut in size and mass provides an equivalent 3-hour F and T rated configuration.
Therefore, HAZ review, similar to that discussed in Section 7.2.3 of M-663-00017A for non-T rated penetration seals, is only necessary for structural steel integral to a fire barrier assembly where either of the following is present:
* Steel is provided with fireproofing on only one barrier side.
* Fireproofing is provided on both steel sides and an unprotected thermal short attachment larger than Unistrut is present.

M-663-00017A                                                                        Page 6 of 15 Attachment G5 Revision W03 6.0    Methodology Where a HAZ review was necessary for steel that is integral to a fire barrier assembly, a review similar to M-663-00017A Section 7.2.3 was conducted with the exception that a review distance of two feet from the unexposed steel surface was utilized. This is an acceptable distance considering the air gap temperature drop discussion provided in M-663-00017 A Section 7 .2.3. This two-foot distance from the structural steel member on the unexposed side is the area that encompasses the HAZ. Assuming an ASTM E-119 three-hour fire duration, a temperature of either 1925&deg;F or 11 00&deg;F was assigned to the unexposed barrier side based on the fireproofing configuration provided, including consideration for unprotected thermal short attachments larger than Unistrut.
A 1925&deg;F temperature was utilized for the following configurations:
* Fireproofing is single sided with an unprotected attachment on either barrier side.
* Fireproofing is provided on both barrier sides and an unprotected attachment larger than Unistrut is located on the fire side such that it is in proximity (within two feet) to an unexposed side attachment that supports a raceway within the HAZ.
An unexposed side temperature assignment of 1925&deg;F for the above configurations is a conservative approach, as it utilizes the maximum temperature attained during ASTM E-119 fire testing, with no credit given for concrete barrier heat sink or recognition that the hot spot created by the unprotected thermal short on the exposed barrier side will be localized.
An 11 00&deg;F temperature was utilized for the following configurations:
* Fireproofing is single sided and no unprotected attachments larger than Unistrut are present on either barrier side.
* Fireproofing is provided on both barrier sides and an unprotected attachment larger than Unistrut is not in close proximity (within two feet) of an unprotected attachment on the opposing barrier side.
An unexposed side temperature assignment of 11 00&deg;F for the above configurations is a an acceptable approach based on subtraction of ASTM E-119 furnace temperature (1925&deg;F) from Reference 3.4 and 3.5 thermocouple data (1, 100&deg;F). This yields an approximate 825&deg;F temperature drop across the exposed fireproofing during ASTM E-119 fire endurance testing.
For PFSSD circuits and IEEE-383 cable, an insult temperature limitation of 700&deg;F was utilized. A temperature limitation of 400&deg;F was utilized for other Class A combustibles.
These temperature limitations are consistent with M-663-00017A, Section 7.2.3.
Figure 6-1 reflects the review process utilized to assess HAZ impact.

The one-sided protection configuration will not allow flame passage through the barrier. However, it could result in temperatures up to 11 00&deg;F or 1925&deg;F on the unexposed steel surface of the barrier. Each room was reviewed for HAZ impact in effort to document each raceway and insitu combustibles within two (2) feet of the barrier segment containing steel protected with cementitious fireproofing to ensure PFFSD is not impacted. In addition, two-side protection with unprotected attachments can also produce localized high temperatures.              Therefore, protected steel with unprotected attachments was also reviewed for HAZ impact at barriers separating fire areas. No credit was given to area suppression systems, in effort to achieve a level of conservatism in the analysis process.
One sided structural steel fireproofing is determined to be "F" rated only and does not satisfy "T" rating requirements when exposed to a design basis fire.
Specification A-126, Section 7.1 states in part, "stair towers and elevator construction shall be protected from external hazards", thus in these cases structural steel fireproofing was not required on both sides of the barrier. Where these barriers provide 10 CFR 50 Appendix R separation, this configuration does not satisfy maximum cold side temperature limitations required by the WCNOC Fire Protection Program (250&deg;F plus ambient for fire barrier construction and 325&deg;F plus ambient for fire barrier penetration seals). Therefore, each location where one-sided fireproofing or significant attachments are present was evaluated for HAZ impact to ensure PFSSD is not affected. As such, any raceway/circuit or component within 2 feet of the one-sided protected barrier steel and/or two-sided protected steel with large thermal shorts will be considered within the HAZ and will be evaluated for PFSSD impact utilizing the Figure 6-1 methodology. Thermal shorts attached to stairwell steel will not impact the structural integrity of the steel or induce steel failure due to the corbel support afforded by the under supporting walls.
Table II defines the review scope and identifies the communicating rooms and fire areas along with the raceways that are potentially subject to thermal insult, based on proximity to the barriers evaluated. Each room and raceway (where applicable) is dispositioned in the "Comments/Disposition" Section of Table II, with reference provided to the appropriate evaluation paragraph section below.
Area walkdown reviews revealed that no insitu combustibles (other than IEEE-383 cable) were located within the HAZ for each of the Table II areas.
Appendix G5A documents the result of the Fire Protection reviews and assessments for each room and area listed in Table II, below. The data sheets contain relevant information for each location reviewed for HAZ impact.

: 1. To determine acceptable air gap distance, conductive pathways, estimated exposure temperature is based on existing steel protection configuration and whether the exposure is C-Conduction or R-Radiant. In each case, the worse case Conductive and Radiant distance is used, either cumulative or a single thermal pathway exposure were reviewed as applicable.

M-663-000 17A                                                                    Page 13 of 15 Attachment G5 Revision W03 7.1.1  Unscheduled conduit such as communication, fire detection and general plant lighting are not considered relevant to PFSSD and are not evaluated for PFSSD impact. Cabling contained within conduit cannot support combustion, propagate flame or hot gases. Therefore, fire propagation is not credible.
7.1.2 Scheduled Non-PFSSD conduits referring to this section are located within the HAZ and cable within the conduits have the potential to sustain damage from heat transmission through the barrier segment fabricated from building steel protected with cementitious fireproofing, as postulated temperature exposure exceeds 700&deg;F for the respective raceway.
However, fire propagation will not occur, as cabling contained within conduit cannot support combustion, propagate flame or hot gases; therefore, fire propagation is not credible. Future use of these raceways shall be restricted or may require field modification if they are credited for PFSSD in the future. E-15000 set-route control is required for these raceways to ensure future raceway use continue to satisfy the conclusions of this evaluation. Referenced E-15000 set-route changes were completed by change package 012323.
7.1.3 Scheduled Non-PFSSD conduit and cable tray raceways referring to this section have been determined to have sufficient distance from the point of thermal insult and will not be thermally affected by conductive or radiant heat on the unexposed barrier side. This determination is supported by use of the air gap methodology described in M-663-000 17A, Section 7.2.3, which credits air space to reduce exposure temperatures to cabling and combustibles within or adjacent to the HAZ. Each HAZ issue was reviewed to ensure combustibles on the unexposed side of the barrier would not be affected by radiant energy and/or auto-ignition. Air gaps and thermal short distances were measured to permit use of the 222&deg;F temperature drop rule for every 1" of air gap. After considering the air gap distance, each of the HAZ issues would have to meet acceptable cable exposures of <700&deg;F. Maintaining exposure temperatures below this limitation will ensure that fire propagation cannot occur, and the raceway will not be affected through conduction or radiant heat.
7.1.4 PFSSD credited conduit or cable tray raceways referring to this section have been determined to have sufficient distance from the point of thermal insult and will not be thermally affected by conductive or radiant heat on the unexposed barrier side. This determination is supported by use of the air gap methodology described in M-663-00017A, Section 7.2.3, which credits air space to reduce exposure temperatures to cabling and combustibles within or adjacent to the HAZ. Each HAZ issue was reviewed to ensure combustibles on the unexposed side of the barrier would not be affected by radiant energy and/or auto-ignition. Air gaps and thermal short distances were measured to permit use of the 222&deg;F temperature drop rule for every 1" of air gap. After considering the air gap distance, each of the HAZ issues would have to meet acceptable cable exposures of <700&deg;F. Maintaining exposure temperatures below this limitation will ensure that fire propagation cannot occur, and the raceway will not be affected through conduction or radiant heat.

M-663-00017A                                                                        Page 14 of 15 Attachment G5 Revision W03 7.1.5     PFSSD credited cable tray 6U3E21, located in Room 3403, is a 12" X 4" open cable tray in close proximity to a 6" x .375 thick I beam that is attached to the building steel. The building steel separates 10 CFR 50 Appendix R fire areas and is protected on the cable tray side with cementitious fireproofing (one-sided protection). The exposed side of the barrier is Room 3201, North Control Building Stairwell.
The cable tray is 23" away from the postulated exposure temperature of 1925&deg;F as determined by the steel configuration and one-side fireproofing. Conservatively applying the M-663-00017A, Table 7.2.3-2B review distance for a 12" diameter pipe, in relation to the 6" beam, reveals that at 24" the thermal exposure would be approximately 1209&deg;F.
Application of the air gap methodology of 222&deg;F drop per 1" air gap reveals an approximate temperature of 543&deg;F for the cables within the tray of concern. This is less than the 700&deg;F insult temperature limitation for the IEEE-383 cable. However, this raceway requires E-15000 set route control to ensure future cable additions consider impact to this evaluation. This E-15000 set-route change was completed by change package 012323.
7.1.6     PFSSD credited conduit 4U3D5H, located in Room 1320 is a 3" rigid steel conduit supported by a 4" tube steel and Unistrut design mounted to the vertical column separating fire areas. The conduit contains PFSSD cabling associated with BIT injection. The building steel separates 10 CFR 50 Appendix R fire areas and is protected on the conduit side with cementitious fireproofing (one-sided protection). The exposed side of the barrier is Room 1127, North Auxiliary Building Stairwell.
The conduit is 4" away and mounted directly on to the conductive path to the postulated exposure temperature of 1925&deg;F, as determined by the steel configuration and one-side fireproofing.        The thermal path is conductive and thermal failure is expected due to the close proximity of the conduit to the exposure temperature of 1925&deg;F. A fire in A-6 does not require BIT injection. Seal injection is available with no inventory loss through letdown. Therefore, PFSSD capability is not affected if a fire would occur in Fire Area A-6. However, this raceway requires E-15000 set route control to ensure future cable additions consider impact to this evaluation. This E-15000 set-route change was completed by change package 012323.
7.2    Post Fire Safe Shutdown Impact There is no impact to PFSSD capability, as the evaluation demonstrates that steel integral to 10 CFR 50 Appendix R fire barriers will prevent fire propagation.
The comprehensive walkdown review for each of the areas revealed that no exposed insitu combustibles or PFSSD capability is negatively affected by the steel fire barrier segments.

M-663-00017A                                                                     Page 15 of 15 Attachment G5 Revision W03 8.0    Conclusions Based on physical plant walk downs, reviews and assessments performed by Fire Protection the room and areas identified in Table II above, contain protected structural steel that separate 10 CFR 50 Appendix R fire areas. Each of these barriers vary in configuration, some with one-sided protection and others with two-sided protection with unprotected attachments that could induce heat through the barrier beyond WCNOC cold side temperature limitations, if an ASTM E-119 three hour fire were to occur in the adjacent fire area. Therefore, each raceway that was located within the HAZ was reviewed for potential impact to PFSSD. All raceways listed in Table II above have been determined to be acceptable and do not affect PFSSD considering the protective coating or thermal short configurations that are present.
It is reasonable to conclude that the building steel integral to a fire barrier will satisfy regulatory expectations and commitments as well as WCNOC Fire Protection Program requirements, to prevent fire propagation and unacceptable thermal insult to raceways on the unexposed side of the fire barrier.
