2.0 Discussion

l Title 10 Part 50 (10CFR50), Appendix R (Reference 3.1) was promulgated to establish

. fire protection features required to satisfy Criterion 3 of 10CFR50, Appendix A.

Appendix R applies to licensed nuclear power electric generating stations that were

operating prior to January 1,1979. GGNS received its operating license after this date; therefore, by law, Appendix R does not apply to GGNS However, Appendix R was
incorporated into the license bases at GGNS as established in UFSAR, Table 9.5-12 " Fire
Protection Program Comparison with Appendix R to 10CFR50"(Reference 3.2). Section i

III.G.2 of Appendix R identifies acceptable means of ensuring safe shutdown capability for areas where redundant trains of safe shutdown equipment are located within the same i fire area outside primary containment.

GGNS compliance strategy for the areas listed in Section 1.0 above is to provide fire f

protection features which meet ee requirements of Appendix R,Section III.G.2.c. These features include enclosing one trais of redundant safe shutdown equipment in a fire barrier having a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> rating, installing fire detectors, and an automatic suppression n system in the fire area. As a result of enclosing electrical cables within this fire barrier, additional electrical cable ampacity derating must be considered.

"Ampacity" is defined as "the current-carrying capacity, expressed in amperes, of a wire or  !

J cable under stated thermal conditions, including conductor temperature, ambient temperature, and installation conditions" (Reference 3.3, section 4.2). Therefore, the ampacity of a cable is the maximum current the cable can carry in a stated ambient ,

temperature without exceeding its specified insulation temperature. Existing industry I

. standards (Reference 3.4) published by the Institute of Electrical and Electronic Engineers

' (IEEE) and the Insulated Power Cable Engineers Association (IPCEA) provide tables of cable ampacities for various combinations of conductor /m~ sulation types. The tables are based on empirical as well as analytical work performed within the cable manufacturing industry. These tables also provide ampacity derating (or correction) factors to account for various installation geometries. "Ampacity deratmg factor" is defined as "A numeric value rereoting the fractional reduction from a base ampacity cable rating. Ampacity derating -

factors are associated with specific installation conditions not addressed in the base ampacity", "Ampacity correction factor" is defined as "A numeric value equal to one ,

minus the ampacity derating factor"(Reference 3.7). j 1he ampacity tables in reference 3.4 do not account for any fire barrier cladding extemal to  ;

open air cable / raceway installations. Therefore, electrical circuits in raceways that have any ]

cladding extemal to the raceway require cable additional ampacity derating to account for )

., the fire barrier cladding. To determine ampacity derating factors for fire barrier cladding, )

testing would have to be performed for the specific fire barrier material, as well as  :

installation geometry. Ampacity derating factors for TSI's Thermo-Lag were based on j testing performed by Industrial Testing Laboratories, Inc. of St. Louis, Missouri, and l documented in ITL Report No. 84-3-275A (Reference 3.5).

During the late 1980s and early 1990s testing was performed by several nuclear power plants on Thermo-Lag fire barriers. These tests yielded results which were not consistent with the test results provided by TSI. The NRC issued Generic Letter 92-08 to highlight

. . the concems raised within the industry. GL 92-08 questioned the validity of the results obtained by Industrial Testing Laboratories, Inc. The principal areas of NRC concem were:

the fire endurance capability oflhermo-Lag 330-1 fire barriers, the ampacity derating of ,

the cables enclosed in ihermo-Lag 330-1 fire barriers, and the evaluation and application of the results of tests conducted to detennine the fire endurance ratings and the ampacity derating factors of Thermo-Lag 330-1 fire barriers (Reference 3.6).  ;

The Insulated Conductors Committee of IEEE's Power Engineering Society sponsored a 3 task force to provide a test procedure to establish ampacity derating factors for cables  ;

enclosed in fire protection barriers. Task force 12-45 of Test and Measurements Subcommittee No.12 issued draft IEEE Standard P 848," Procedure For the Determination i of the Ampacity Derating of Fire Protected Cables"(Ref. 3.7) for that purpose. IEEE P848 {

is still in draft form, and is cunently at draft 16. Despite being in draft form, the standard I has been utilized to perform ampacity derating testing by some nuclear utilities, in order to facilitate obtaining their operating licenses. Texas Utility Electric (TUE) and Tennessee Valley Authority (TVA) were among the first utilities to perform testing per drafts of IEEE P848. While the NRC has not formally endorsed this draft standard, they have accepted j submittals from utilities which utilized the draft standard to address ampacity concems for j Thermo-Lag clad raceways. In addition to that, the NRC has evaluated these submittals, -

and after a comment cycle, agreed upon appropriate derating factors with the liscencee. J This implies the NRC's acceptance ofIEEE P848 to perform ampacity derating testing for i fire barrier cladding. i 1

Engineering Report No.: GGNS-96-0006 Page 5 of 17 Revision 0 i

TUE's Comanche Peak Steam Electric Station (CPSES), Unit 2 had ampacity derating testing performed by Omega Point Laboratories, per IEEE P848 Draft 11. Results from this ,

testing program were submitted to the NRC by TUE in response to Generic Letter 92-08. l The NRC, with input from Sandia National Labs (SNL), evaluated TUE's submittal and  !

identified concems regarding some testing methodologies utilized by TUE. Based on I

TUE's subsequent responses and additional input from SNL, the NRC published a Safety

Evaluation Report (References 3.8) for ampacity issues related to Thenno-Lag fire barriers at Comanche Peak Steam Electric Station (CPSES), Unit 2. This Safety Evaluation Report (SER) was also released to other nuclear power plants. In their SER, the NRC revised the ampacity derating factors presented by TUE. SnecinenHv. the amaneity deratine factor i for i Hr Thermo I.ma clad conduite was reviaa<t from 11 % deratine to 21 % deratine.

Safe shutdown Conduits clad with Thermo-Lag fim barriers rated for 1 hr at GGNS have a similar configuration to the I hr Thermo-Lag configurations tested per IEEE P848 Draft i 1 by TUE. This report will present comparisons to demonstrate that the tested configurations ,

bound comparable GGNS installations.

4.0 Assumptions

i I i 4.1: Electrical raceway materials and cables procured for the construction of nuclear

power plants of the same vintage were govemed by the same requirements.

' Consequently, nuclear power plants of the same vintage have similar electrical  !

raceway materials and cables installed. .I t 4.2 Rigid steel conduits procured for the construction of GGNS and CPSES were l manufactured using similar processes, and therefore will have similar  !

characteristics. 4

. 4.3 The effect of the cable insulation type does not have an impact on the ampacity h derating testing, since it primarily functions as a heat generating source within the i raceway. Therefore, even if a different grade insulation was utilized for the testing,  ;

it would not change the ampacity derating for the conductor within the tested  :

1 raceway. Note. bowever. that the conductor insulation type does become  !

critical when determining the base ampacity of the conductor or cable.

which is rated for a conductor operating temperature of 90 = C.

1 5.2 The 10% margin added by the NRC to TUE's 11% derating for rigid steel conduits, ,

accounts for test protocol uncertainties, includmg variations in conduit properties for  ;

l i conduits within CPSES stocks. )

  • C, to be 30 A.

When corrected for a conservative ambient temperature of 40 ' C (0.91 .

! multiplication factor), the ampacity of this cable is reduced to 27.3 A. Since the  :

NEC limits overcurrent protection for # 12 AWG conductors to not exceed 20 A, an i ampacity of 20 A will be assumed for additional conservatism. Additionally, an j adjustment factor of 50 % is applied to account for 43 or more conductors under the l

same raceway or cable (Note 8 to Ampacity Tables of 0 to 2000 Volts, page 70-165 4

Ref. 3.9). The final adjusted ampacity for # 12 AWG conductors within the scope of this evaluationis 10 A.  !

.. Note that excepti6nTto the ampacity tabics wr.ives the adjustment factor for non .

To account for multiple conductors within one conduit (cables without maintained ,

which is reproduced below. .

In order to detennine the appropriate base ampacity for a specific power cable within a specific conduit, the proper ampacity for the conductor size is multiplied by the factor corresponding to the nu'nber of conductors within the conduit. As an example, a 4 AWG cable within a conduit with 8 total conductors would have an ampacity of 63.7 A.

Therefore, the circuit loading (assumed and actual) is for steady state operation, and l' does not factor in transient conditions (e.g. inrush current), or any future design margins. ,

6.0 Analvnis-

~

The basis for the use of ampacity derating factors identified by the NRC in their SER j (Reference 3.8) rests on demonstrating the following points:

l I

e The Thenno-Lag fire barrier installation tested by TUE bounds the installations at  !

GGNS that are being evaluated by this report. i

. . The electrical materials used for the test bound the electrical materials utilized at l GONS for the installations being evaluated by this report.  :

Once the basis has been established for using these ampacity derating factors for GGNS, an

ampacity evaluation can be performed to determine whether the cables within the scope of  :
this evaluation are adequately sized.  ;
i 6.1 Therma Imo In=*allatian Camnariaan  ;

The purpose of this section is to establish that Thermo-Lag configurations ,

identified in Engineering Standard ES-02, Rev. 2, which utilize the 1/2" base

. . and/or 1/4" overlay Thermo-Lag material, are bounded by the Thermo-Lag configurations previously tested for ampacity derating and documented in Omega  ;

Point Laboratories Report No.12340-94583,95165-95168,95246 "Ampacity  !

Derating of Fire Protected Cables"(Reference 3.13). Specific portions of ES-02 which pertain to the use of 1/2" base Thermo-Lag material are: New Installations

'(Section 13.1) and Repair of Existing Thermo-Lag Enclosures (Section 13.3).

As it relates to ampacity derating, the following are considered critical parameters  !

for comparison purposes: Material Type, Material Thickness, Stress Skin l Location, and Raceway / Base Material / Overlay Material Interface Mechanisms. A  ;

comparison of the GGNS configurations, as identified above, and configurations l utilized in the Omega Point Laboratories test for each of the identified critical i parameters are discussed in detail below. j i

l-I 6.1.1 W~ial Tvne i l L Thermo-Lag materials utilized at GGNS are: 330-69 stress skin,' 330-1 prefabricated panels (V ribbed),330-1 prefabricated conduit sections,330- a 1 subliming coating (trowel grade),330-660 Flexi-Blanket, and 330-660  !

bulk material (trowel grade). A review of Thermo-Lag materials utilized

)

in the Omega Point Laboratory test determined that they are identical to j those utilized at GGNS with one exception. The one exception is that Omega Point Laboratory test used Thermo-Lag 350 Topcoat on both prefabricated panel and conduit sections. This 350 Topcoat is a two part  ;

water-based mixture which is applied in a thin layer to improve water repellent characteristics. With regard to ampacity derating, the 350 1 Topcoat material will have no affect. Therefore, with regard to material l type, the GGNS materials are considered bounded by the Omega Point l Laboratory test.

6.1.2 Material Thickness 1

Material thickness of the Thermo-Lag 330-1 nominal 1/2" thick  ;

prefabricated panel & conduit sections and the nominal 1/4" thick prefabricated conduit overlay sections are identical for the GGNS and Omega Point Laboratory test materials. For the Thermo-Lag 330-660 Flexi-Blanket both GGNS and Omega Point Laboratory test used a volumetric requirement. For Thermo-Lag 330-660 Flexi-Blanket, minimum weight was 1.6 lbs/ square foot and maximum weight was 2.3 lbs/ square foot. These volumetric requirements were used in both the Omega Point Laboratories test and ES-02. In addition, construction and thickness of reinforcement techniques in both are identical. Therefore, with regard to material thickness, the GGNS materials are considered bounded by the Omega Point Laboratory test.

6.1.3 Stress Skin Location Stress skin is located on the inside surface of the 1/2" base materials and the 1/4" overlay materials for both the GGNS configurations and the configurations tested in the Omega Point test. In addition, stress skin location with regards to reinforcements techniques are identical.

However, for those configurations identified in ES-02, Sections 13.1.3.b.1 i & 12 (Conduits >.3/4 and bounded by NEI Generic Fire Test 1-

6) there are various reinforcements which are not included in the Omega Point Laboratories ampacity derating test. Therefore, with the exception of configurations identified in ES-02, Sections 13.1.3.b.11 & 12 (Conduits

Engineering Report No.: GONS-96-0006 Page 12 of 17 Revision 0 62.1 Conduits 2 The conduits utilized by TUE for the testing, and installed at CPSES are made out of rigid steel. Since CPSES is a similar vintage plant as GGNS,

the conduits were procured around the same time frame and subject to the same manufacturing standards and processes. Therefore, the conduits
should have similar characteristics as those that were tested. The 10%

derating factor added by the NRC to TUE's 11% derating has factored in the h necessary margin to account for differences in conduit fabrication for that

penod.

6.2.2 ~ Cabics

. The cables tested were XLP with hyphalonjackets. These were chosen to i bound all common cable types utilized within the nuclear power industry.

- The power cables utilized within affected GGNS installations have EPR insulation. Again, since CPSES is the same vintage plant as GGNS, it has similar EPR cables within their installations (Reference 3.18). Therefore, the cable types utilized for the testing and those installed at CPSES are similar to the GGNS installation. Since the tests bound EPR cables installed at

! CPSES, they bound the EPR cables installed at GGNS. Additionally, for the purposes of ampacity derating testing, the insulation type on a conductor has no impact on the derating factor si nce the conductor is merely behaving 4 as a heat source within the raceway.

6.2.3 Conclu= inn 1

The above discussion provides sufficient basis to demonstrate that the

electrical installation tested by TUE bounds the GGNS electrical
installations being evaluated by this repon.

6.3 Amnacity Evaluation Wires and cables are utilized to connect various types of circuits, operating at different voltage levels. At GONS, electrical circuits are segregated by voltage levels. These voltage levels include " Power and Control (120-480 V)", and

" Instrumentation". These two voltage levels account for all circuits being evaluated by this repod. These circuit applications are addressed below.

6.3.1 In=trumentation Annlicatinns ,

The instrumentation applications within the scope this evaluation consist of thermocouple circuits and nuclearinstrumentation circuits. The ,

r Engineering Report No.: GGNS-96-0006 Page 13 of17 Revision 0 thermocouple circuits operate on the thermocouple principle, and transmit

.. voltages in the millivolt range to indication devices, via thermocouple extension cables. The nuclear instrumentation circuits transmit DC voltage o pulses in the 0-10 VDC range over coaxial cables.

The instrumentation circuits discussed above operate at very low voltages, i and do not have any cable heat rise associated with their application. ,

Circuits and raceways which are designated as " Instrumentation"

consequently do not need any rigorous analysis for ampacity derating.

Therefore. allinsduuw=*=*In_= circuinc and racewavs &*Mn the cen_=_ = of oMe r;=!- -+- will not be L.23 for --+c.

6.3.2 Power and Control Annlistions (120 - 480 V)

Cables for 120 to 480 V power and control applications are generally routed

[j in common raceways. The majority of the raceway fill is typically 120 V i control cables (generally # 12 AWG), with some power cables for loads like j fan motors, panel power supplies, etc. For cables within the scope of this

! evaluation, power applications utilize cable sizes larger than # 12 AWG, with one exception. The exception is use of # 12 AWG cables to provide power to space heaters, which draw less than 3 A when energized. Power j- and control applications are further evaluated separately below.

l. 6.3.2.a Cantml Annlistians Within the power and control classification, control circuits are
- generally limited to 120 V. Circuit applications that fall under i this category include control relays ( typically Agastat, Potter-Brumfield, etc.), solenoids for air operated valves (AOVs) and
safety relief valves (SRVs), and remote annunciators, indicators, j and status lights (generally main control room). The bulk of these control circuits utilize # 12 AWG cables, carrying less than 3 A of current. A typical control relay draws less than 0.25 A, while a typical control solenoid draws less than 1 A of current.

, Annunciators, indicators, and status lights generally draw less

. that 0.25 A (References 3.18 & 3.19). In addition to the control j applications, some power applications can be addressed here. As 4 discussed earlier, some # 12 AWG cables have been used for power circuits (space heaters), however, since they draw less than 3 A, the analysis above bounds their application. Therefore

( these circuits will not be addressed under power applications e

addressed under section 6.3.2.a, and will not be discussed further in this section. The latter is discussed under this section. As
discussed earlier, power circuit loads for the circuits being ,

l IPCEA P-46-426 (reference 3.4), and NEC-1990 (reference 3.9). l Base ampacities are calculated from the cited sources, and j

, multiplied by an ampacity correction factor of 0.79 to obtain the  ;

As discussed within the body of this report, instrumentation circuits, by virtue of their function do not require any ampacity derating. Attachment I lism all instrumentation  ;

circuits within the scope of this evaluation, but does not incle:'e any ampacity or derating i information for these circuits.  :

)

l Control circuits typically utilize cables with #12 AWG conductors, and carry less than 3 j Amperes. Some power applications within the scope of this evaluation have utilized # 12  ;

AWG conductors, but all of these have current loadings ofless than 3 A. Therefore, these '

l

~circuits are bounded by the treatment of#12 AWG conductors applied for control circuit applications. Note that these cables all have a minimum margi:1of 62 % available.

Power circuits generally utilize cables with conductors larger than # 12 AWG, with the execytions noted earlier. A review of attachment I shows that the worst case margin for power cables is 28.4 percent. This signifies that all power cables within the scope of this evaluation are carrying less than their derated ampacity.

Based on the evaluation of the circuits within the scope of this report, all cables are adequately sized to carry their designed current. Therefore, all cables within GGNS raceways that are covered by 1 hr Thermo-Lag fire barrier material are have sufficient ampacity to cany their designed loads.
