WCNOC Response Wolf Creek Generating Station (WCGS) relies upon Thermo-Lag 330-1 fire i
d barriers to meet 10 CFR 50.48 (e), which is implemented at WCGS by NRC guidance l
provided in Branch Technical Position CMEB 9.5-1.
A listing of these WCGS i
applicaticns is provided in Table 1 (attached), which identifies the purpose, fire rating, type, and dimension of each barrier.
WCGS also utilizes Thermo-Lag 330-1 barriers to meet Regulatory Guide 1.75 j

j Attachment to WO 94-0013 Page 3 of 18 WCNOC RESPONSE i
j The response to Item II has been divided into two sections.
The first one addresses the twenty-four parameters of importance to Thermo-Lag 330-1 f
material installation.
The second addresses the eight parameters of importance concerning cable protected by fire barriers.
i j
Raceway Fire Barrier Parameters WCNOC has been actively evaluating WCGS Thermo-Lag 330-1 applications relied upon to meet BTP CMEB 9.5-1 requirements. WCNOC has obtained and verified the 24 parameters listed in the RAI for WCGS BTP CMEB 9.5-1 applications.
This j
information was obtained and/or verified through the use of general walkdowns, j
design drawing reviews, and review of QA records of the applications.
It should be noted that additional rated fire barrier parameters, including fire barrier panel rib location, raceway gauge (mass), type of cable tray side rails, cable tray rung spacing and thermal shorts penetrating the barrier but not contacting the raceway, have been identified as potentially important.
In addition, the planned NUMARC Phase 2 testing could result in identification of further fire barrier parameters of importance or demonstrate that some of the exiting fire barrier parameters are not significant.
1 It is WCNOC's intent to utilize the fire barrier performance parameters specified in the final Application Guide as issued by NUMARC and. agreed upon by the NRC when evaluating fire barriers for acceptability.
As requested in Action Item II.B.1, detailed information is available on-site for NRC audit of the known parameters.
l l
Cable Parameters Cable functionality is presently an unresolved issue, and NUMARC is not currently conducting any cable functionality. tests or evaluations as part of 4
its Phase 2 Test Program.
Conduit in the NUMARC tests use a bare copper a
4 conductor.
WCGS has very limited applications of Thermo-Lag 330-1 on cable trays.
There t
are two applications of 3-hour rated Thermo-Lag 330-1 on a 24" x 4" tray for a length of approximately eleven feet each.
j If NUMARC fire tests demonstrate temperature criteria exceedance, one optional approach to resolution, as provided in the NRC draft test and acceptance j
criteria, would be to evaluate cable functionality at the elevated temperature j
j using cable performance test data or information for specific installed cable l
types.
However, the NRC has not yet finalized requirements for cable I
functionality evaluation, and test results are not yet available that would clearly indicate the scope of such evaluations.
i Based on the above, WCNOC does not intend to obtain and verify the eight listed parameters for each of the WCGS applications for the purposes of this response.
However, if the results of the NUMARC testing does warrant cable functionality evaluations on an application specific
- basis, and NRC requirements have been finalized for that type of evaluation, WCNOC will 4
4 e
r
Attachment to WO 94-0013 Page 4 of 18 obtain and verify the necessary cable parameters on an at
. cation speci.fic basis.
The WCGS Thermo-Lag 330-1 applications installed to meet Regulatory Guide 1.75 requirements are not intended to meet 1-hour or 3-hour rated fire barrier configurations.
Therefore, the twenty-four fire barrier parameters of importance referenced in Section II A of the RAI, are not all applicable to the Regulatory Guide 1.75 applications.
Parameters such as location, material thickness, and material amounts have been obtained for WCGS Regulatory Guide 1.75 applications.
These parameters may be necessary to evaluate these applications for ampacity derating and to perform a material conbustibility screening.
Chemical testing performed by NUMARC on a wide variety of aged samples has not revealed significant variations in chemical composition.
NUMARC intends to discuss these test results with the NRC and distribute them, along with the Phase 1 test reports, to the various licensees.
Further, NUMARC has indicated
.j that Phase 2 testing will include additional chemical testing on barrier j
materials of various ages.
Unless unexpected results are encountered, plant unique chemical evaluation should not be necessary.
Therefore, WCNOC does not have any plans at this time to conduct material chemical testing.
RAI Section III THERMO-LAG FIRE BARRIERS OUTSIDE THE SCOPE OF THE NUMARC PROGRAM III.B.1.
Describe the Larriers discussed under Item I.B.1 that you have determined will not be bounded by the NUMARC test program.
III.B.2.
Describe the plant-specific corrective action program or plan you expect to use to evaluate the fire barrier configurations particular to the plant. This description should include a discussion of the evaluations and test begin considered to resolve the fire barrier issues identified in GL 92-08 and to demonst rate the adequacy of existing in-plant barriers.
III.B.3.
If a plant-specific fire endurance test program is anticipated, describe the following:
a.
Anticipated test specimens.

Test methodology and acceptance criteria including cable functionality.
WCNOC RESPONSE As discussed in the April 16, 1993 WCGS response to NRC Generic Letter 92-08 (Letter ET 93-0047, F.
T.
Rhodes, WCNOC, to USNRC) the WCGS rated fire barrier applications can be classified into two categories.
The first category (typical fire barrier applications) includes conduit, with their associated junction boxes and supports, and cable tray.
The second category (WCGS unique applications) includes various hatch covers, a cable tray fire stop and a single encapsulation box.
Attachment to NO 94-0013 Page 5 of 18 1
The first category falls within the scope of the NUMARC test program in terms j
of applications, fire barrier ratings, raceway types, raceway sizes and j
configurations.
~
The second category is outside the scope of the NUMARC test program. The'WCGS unique fire barrier applications are:
i 1.
Tendon Surveillance Access Hatches in the Auxiliary Building - at Elev. 2020'-0" (2 hatches) and 2047'-6" (2 hatches).

Auxiliary Building at Elev. 1989'-0"-
l l
5.
Cable Tray Fire Stops in the Corridor between the Component l
Cooling Water Pumps in the Auxiliary Building at Elev. 2026'-0".
l WCNOC has completed a detailed evaluation of each of the above fire barriers.
Resulta of these evaluations are as follows:
i l
1.
Tendon Surveillance Access Hatches in the Auxiliary Building at f
Elev. 2026'-0" (2 hatches) and 2047'-6" (2 hatches).
i At each elevation identified there are two hatches which consist I
of a 2'-10" x 3'-3" x 1/4" checker steel plate with a 1" layer of Thermo-Lag 330-3 material bolted on the top side..The covers rest I
on 5" x5" x1/2" steel angle supports attached to concrete walls on i
two sides and to concrete curbs on the other two sides. The steel plate and the angle supports are covered with Albi-Duraspray l
fireproofing material on the bottom side.
The hatch covers serve to provide separation between fire areas'within the plant.
i
^
The detailed evaluation determined that the as-installed hatches represent a non-rated fire barrier which affords protection from fire based on the hazards present in the fire areas.
Therefore, l
no further work is required for this item.
l 2.
Residual Heat Removal (RHR) and Containment Spray Encapsulation I
Access Covers in the Auxiliary Building at Elev.
2000'-0" (2
access covers).
j The two access covers located in the floor of the auxiliary i
building at elevation 2000'-0" consist of openings that are approximately 10'-6" x 12'-6" with C15 steel channel frames around the perimeter of the opening on top of 18" high curbs.
The barrier is made of 4"x4" tube steel in a grid with 1" Thermo-Lag 330-1 material panels.
The channel steel is covered with I
i
t l
Attachment to WO 94-0013 Page 6 of 18 j
Albi-Duraspray fireproofing material.
The hatch covers are provided as a separation between two fire areas in the plant.
i
?
The detailed evaluation determined that, due to' the large unsupported span of Thermo-Lag 330-1 material, installation of 1/4" steel plating in lieu of the existing Thermo-Lag panels would provide a.non-rated fire barrier suitable'for the hazards present
' i in the two fire areas.
Therefore, a plant modification-has been initiated to replace the Thermo-Lag 330-1 panels on the RHR and Containment Spray Encapsulation Access Covers with 1/4" steel plate.
l l
3.
Box type enclosure of motor operated valve AL-HV-32 supplying
- I Essential Service Water to the Turbine Driven Auxiliary Feedwater f
Pump (AFWP) in the Auxiliary Building at Elev. 1989'-0".
j The 4'-9" Lx 3'-0" Wx 5'-0" H enclosure is constructed of 1"
Thermo-Lag 330-1 material on 5 sides with the sixth side against a.
ccncrete wall.
- l Both Turbine Driven AFWP suction. valves are located within the i
same fire area. This fire. barrier provides separation between the'
(
two valves to ensure that a suction source for the Turbine Driven-l AFWP is available, as required by BTP CMEB 9.5-1, for areas which do not have installed suppression systems.
The detailed evaluation determined that an equivalent method of f
compliance with BTP CMEB 9.5-1 requirements could be achieved with
[
the addition of fire detection and fire suppression to the area, since the redundant Turbine-driven AFWP suction valves have more l
than the required 20' horizontal separation.
This would ' allo'w j
removal of the box-type enclosure.
Therefore, a
plant
.}
modification has been initiated to add fire detection and fire suppression to the area, and to remove the box enclosure.

~
The 3'-0" x
3'-0" hatch installed in the floor at elevation j
i 1989'0" is covered by a 1/4" steel plate that has a hinge on one l
side. The underside of the plate is covered by 1" Thermo-Lag 330-l 1 material. Embedded steel around the perimeter of the opening is covered with the same Thermo-Lag material and a minimal amount of l
the 1 1/2" thick Albi-Duraspray on the vertical leg of the 6"
angle iron supporting the cover.
The hatch cover provides a fire barrier between two fire areas in the plant.
The detailed evaluation determined that the as-installed hatch l
cover represents a non-rated fire barrier suitable'for the hazards present in the two fire areas.
Therefore,.no further work is.
required for this item.

Cable Tray Fire Stops in the Corridor between the Component f
Cooling Water Pumps in the Auxiliary Building at Elev. 2026'-0".
l The cable tray fire stops extend for a total length of 3'-0" along l
cable trays-6USE, 6U5D and 6J5B.
The fire stops consist of 1/2" thick Thermo-Lag 330-1 panels which form'a 3'-0" long box around each of the 24" ladder back cable trays.
Within the Thermo-Lag box there is approximately 9" of Dow corning 3-6548 silicone foam between two 1/2" thick Thermo-Lag panels installed vertically in the tray to act as damming boards.
Trays 6U5E, 6USD and 6J5B are totally enclosed in a solid steel cover for a distance of approximately 10 feet in one direction and 25 feet in the other direction from the fire stop.
l t
The fire stop was installed adjacent to the sprinkler protected area of Room 1408 based upon an original licensing concern that the non-safety related cables in these trays were intervening combustibles between two redundant safe shutdown trains in this
- area, The fire stop is intended to'stop flame propagation along the cables in the above mentioned trays.
The detailed evaluation determined that the presence of Thermo-Lag
(
material in the fire stops on cable trays 6U5E, 6USD and 6J5B will
]
i not degrade the performance of the configuration as designed.
j Therefore, no further work is required for this item.
j As a result of the above evaluations and design changes, WCNOC currently has no plans to conduct plant-specific testing of any WCGS-specific fire barriers.
No discussion of the WCGS Thermo-Lag 330-1 applications installed to meet the requirements of Regulatory Guide 1.75 has been included in response to this item.
These applications are not intended to meet 1-hour or 3-hour rated fire i
barrier configurations.
Therefore, the NUMARC fire endurance program.is not j
applicable to them.
I RAI Section IV AMPACITY DERATING IV.B.1.

Describe all corrective actions needed and submit the schedule for completing such actions.
r IV.B.4.
In the event that the NUMARC fire barrier tests indicate the need 1
to upgrade existing in-plant barriers or to replace existing Thermo-Lag barriers with another fire. barrier system, describe the alternative actions you will take (and the schedule for performing j
those actions) to confirm that the ampacity derating factors were derived by valid tests and are applicable to the modified plant design.
Your response to Section IV.B may depend on unknown specifics of the NUMARC ampacity derating test program (e.g.,
the final barrier upgrades).
- However, your response should be as complete as possible.
In addition, your response i
should be updated as additional information becomes available on the NUMARC program.
WCNOC RESPONSE As discussed in the April 16, 1993 WCNOC response to NRC Generic Letter 92-08 (Letter ET 93-0047, F.
T.
Rhodes, WCNOC, to USNRC) WCGS ampacity derat.ing factors for conduit and cable trays covered with Thermo-Lag 330-1 are based on vendor supplied heat transfer coefficient values for Thermo-Lag 330-1.
During_
f original design, WCNOC performed heat transfer calculations to address the specific applications and provide the basis for ampacity derating.
The ampacity derating values are not based on ampacity derating tests.
Conservatism was used in the assumptions made to bound operating parameters.
.l The generic concern with the acceptability of ampacity derating factors is that long term life of the cable insulation may be degraded due to a potentially higher operating temperature for the cable.
WCNOC has evaluated WCGS Thermo-Lag 330-1 applications of conduits and cable trays for ampacity margin.
Ampacity margin is the percentage difference between the actual current of the cable and the acceptable current of the t
cable not including the thermal insulating effects of Thermo-Lag.
It was determined that WCGS has very conservative ampacity margins ccmpared to results of tests performed by other organizations.
The ampacity margins will be applieo to future upgrades as appropriate.
Furthermore, WCGS Class 1E electrical cables are qualified for a 40 year life and have been in service less than one-quarter of the qualified life.
WCNOC currently has no plans to evaluate instrumentation and control cable as i
they do not carry a significant current compared to the ampacity of the conductors.
Furthermore, the heat generated is not significant compared to that generated by power conductors.
i WCNOC also does not intend to evaluate ampacity deratings on fire barrier f
configurations which enclose a raceway for six (6) inches or less in length.
This is based on the assumption that this small an area will not create a significant temperature rise.
NUMARC has not yet determined an exact method to test configurations for ampacity derating associated with fire barrier material.
Although it is currently anticipated that most WCGS Thermo-Lag 330-1 applications on cable
Attachment to NO 94-0013 Page 9 of 18 tray and conduit will be bounded by the NUMARC testing, it is not possible to determine exactly which WCGS barriers will be bounded by the NUMARC testing program until the scope of the NUMARC testing has been finalized.
Therefore, the specifics of the additional testing and evaluation needed to envelop the ampacity derating configurations to the NUMARC program can not be specified at this time.
Furthermore, any schedule proposed at this time for conducting additional testing and evaluations for ampacity derating would be speculative, since the scope of the NUMARC testing has not yet been defined.
As indicated above, the need for and future scope of additional testing and evaluations by WCNOC for ampacity derating will be based on the results of the NUMARC test program.
Depending on those results, WCNOC intends to perform one of the following options:
If the NUMARC test results indicate that WCGS fire barriers need to be modified, WCNOC will determine an acceptable ampacity derating for the new configurations by:
- 1) following NUMARC's ampacity derating tests, or 2) analysis of the new configuration using heat transfer techniques, or 3) performing additional testing beyond the scope of the NUMARC I
tests, or 4) a combination of the above.
If the NUMARC test results indicate that WCGS fire barriers are
- adequate, and NUMARC conducts ampacity derating tests following completion of the fire barrier tests; then WCNOC will address the issue as mentioned above.
If NUMARC does not perform the ampacity derating tests, WCNOC will acquire test methods and results from other organizations which have already performed ampacity derating tests.
WCNOC will then analyze the test methods and results to determine an acceptable resolution to the issue by:
- 1) using the test results as applicable, or 2) evaluating the configurations with heat transfer techniques, or 3) perform additional testing, or 4) a combination of the above options.
This response is applicable for both Regulatory Guide 1.75 and BTP CMEB 9.5-1 i
applications.
l RAI Section V ALTERNATIVES V.B.
Describe the specific alternatives available to you for achieving compliance with NRC fire protection requirements in plant areas that contain Thermo-Lag fire barriers.
Examples of possible alternatives to Thermo-Lag based upgrades include the following:
1.
Upgrade existing in-plant barriers using other materials.
2.
Replace Thermo-Lag barriers with other fire barrier materials or systems.
l 3.
Reroute cables or relocate other protected components.
j i
4.
Qualify 3-hour barriers as 1-hour barriers and install detection and suppression systems to satisfy NRC fire protection requirements.

WCNOC RESPONSE l
f In the event the NUMARC Phase 2 tests which bound the WCGS applications are not successful, or if additional WCGS evaluations using the NUMARC Application Guide indicate that some upgrades that rely on additional thicknesses of f
Thermo-Lag material (or other fire barrier materials) may not be practical due to the effects of ampacity derating or clearance problems, alternative methods exist to restore the fire barriers to operable status.
The following is a discussion of some of the alternatives available.
However, the following discussion is not meant to limit WCNOC to only those methods described.
- 1. The majority of WCGS applications involve 3-hour rated fire barriers.
If the NUMARC test results indicate that some WCGS configurations would j
not pass a 3-hour fire endurance test, evaluations, based upon the use of fire modeling in conjunction with NUMARC baseline (noa-upgraded) test j
results, may be performed to demonstrate adequate protection for the j
installed hazard.
Alternatively, or in conjunction with the above j
evaluations, probabilistic safet" analysis (PSA) could be used as an exemption basis, by demonstrating insignificant core damage frequency i
impacts, assuming barrier inoperability.
- 2. Reroute of cable, or replacement of specific cables with fire rated cable (i.e., Rockbestos Firezone R) 3.
If NUMARC Phase 2 testing is successful but evaluation using the NUMARC Application Guide indicates that the specific WCGS applications are not bounded due to differences in baseline Thermo-Lag 330-1 installation details, WCNOC can rework the WCGS baseline installations to achieve compliance with the as-tested NUMARC configurations.
- 4. In many WCGS applications it would be possible to install fire l
suppression and fire detection to the area and then qualify the existing 3-hour barriers as 1-hour rated barriers.
5.
Performing a
re-evaluation of engineering analyses used for determination of safe shutdown pathways, equipment, and actions, could provide a basis for reduction in the scope of protected circuits and their associated fire barriers.
- 6. For certain applications, WCNOC could replace the Thermo-Lag fire barrier with rated fire barriers using other qualified materials or systems.
7.
If the NUMARC tests of fire barrier upgrades using Thermo-Lag material are not successful, upgrades using other fire barrier materials may be developed.
However, test and acceptance criteria have not yet been finalized and issued by the NRC.
The final approved test methods and acceptance criteria must be evaluated to determine net effect on the l
scope and complexity of upgrades to WCGS installed barriers before this option could be chosen.
The WCGS applications of Thermo-Lag 330-1 material installed to meet the requirements of Regulatory Guide 1.75 are not intended to meet 1-hour or l
3-hour rated fire barrier configuration requirements.
Future ampacity I
Attachment to WO 94-0013 Pam 11 of 18 derating evaluations, or combustibility evaluations, for these applications may indicate Thermo-Lag 330-1 material is not suitable for use in specific applications.
In this event, the Thermo-Lag 330-1 material will be replaced with an alternate material which is suitable as a radiant energy shield.
i RAI Section VI SCHEDULES i
VI.B. Submit an integrated schedule that addresses the overall corrective j
action schedule for the plant. At a minimum, the schedule should address the following aspects for the plant:

1.
Implementation and completion of corrective actions and fire barrier upgrades for fire barrier configurations within the scope i
of the NUMARC program.
]
2.
Implementation and completion of plant-specific analyses, testing, I
or alternative actions for fire barriers outside the scope of the NUMARC program.
WCNOC RE, 'ONSE The WCGS schedule is subdivided into tnree smaller schedules, each one addressing the different application categories.
)
1)
WCGS UNIQUE APPLICATIONS l
As discussed in our response in Section III, the engineering evaluation of each of the WCGS unique Thermo-Lag 330-1 applications is complete. A Plant Modification Request (PMR) has been developed to modify several of these applications as discussed in Section III.
This PMR will be implemented by December 30, 1994 2)
WCGS REGULATORY GUIDE 1.75 APPLICATIONS WCNOC has evaluated WCGS Thermo-Lag 330-1 applications of conduits and cable trays for ampacity margin.
Ampacity margin is the percentage difference between the actual current of the cable and the acceptable current of the cable not including the thermal insulating effects of Thermo-Lag.
It was determined that WCGS has very conservative ampacity margins compared to results of tests performed by other organizations.
These ampacity margins will be applied to future upgrades as appropriate.
It is WCNOC's intent to evaluate and utilize the ampacity deratings derived by Texas Utilities Electric Company for these applications once NRC acceptance is obtained.
A schedule for completion of this activity will be provided to the NRC by July 15, 1994.
3)
WCGS PTP CMEB 9.5-1 APPLICATIONS WITHIN THE SCOPE OF THE NUMARC TEST PROGRAM.
Attachment to WO 94-0013 Page 12 of 18 i
Numerous uncertainties currently exist within the NUMARC program as l
noted in several of the above responses.
It is WCNOC's intent to begin detailed engineering evaluations for potential application upgrades as l
soon as the NUMARC Application Guide is received.
The extent of specific upgrades will be based primarily on the level.of success of j
l NUMARC's Phase 2 Test Program.
The following is a schedule provided by l
NUMARC for their Phase 2 testing and ampacity testing.
l l
Activity Schedule Issue Phase 2 test reports April 15, 1994 i
Issue Application Guide April 15, 1994 i
Ampacity program information April 29, 1994 j
Perform ampacity testing July 1994 (estimated)
Issue Ampacity test reports August 1994 (estimated)
Before any upgrades using Thermo-Lag 330-1 or other barrier materials can be approved for the WCGS 3-hour rated applications, the ampacity derating testing for the upgrade must be completed.
Because the NUMARC schedule for ampacity j
derating testing is estimated, an integrated schedule for this activity will be provided to the NRC by July 15, 1994.
It is WCNOC's intention that restoration of fire barrier operability will be complete prior to startup from the WCGS eighth refueling outage, which is scheduled for the spring of 1996.
