! The purpose of this calculation is to determine the ampacity of cables enclosed by Thermo-Lag at Millstone Unit 1. This calculation was done in response to NRC Generic Letter 92-08.

SUMMARY
QE RESULTS:
There are three installations at Millstone Unit 1 that relied upon Thermo-Lag for Compliance to 10 CFR 50 Appendix R.
The application of Thermo-Lag around electrical cables has added another derating factor to be applied to the determination of cable ampacity beside existing code derating factors.
Taking into account the Ampacity Correction Factor (ACFtsi) of.771 for the installation of Thermo-Lag has not caused any electrical cable overloading conditions on Unit 1. Even for the worst case cable derating scenario, the subject cable still had an extra ampacity margin of 34% after applying the Ampacity Correction Factor. ,
The results of this calculation are presented in Section 6, paragraph D.

! DESIGN INPUTS:
A. Thermo-Lag Installations:
Thermo-Lag Installations were identified from raceway drawings and by field walkdowns. Attachment A, pages A-1 to A-13 show detailed sketches of all the Thermo-Lag installations. The reference raceway drawings from which the sketches in Attachment A were prepared are listed on the individual sketches.
B. Cable Loading:
Attachment B, pages B-1 to B-2, identifies the electrical load on the cables protected by Thermo-Lag. Listed along with the electrical load values are references to sources for which the load values were obtained. Load values were obtained from documents such as: Unit 1 & 2's OPAL programs, PMMS, and One-Lines.
C. Cable Ampacities:
l Cable ampacities for the various cables in conduit or air were obtained from l IEEE - IPCEA Standard P46-426; pages 260 & 264-

l D. Ampacity Correction Factor for Thermo-Lag: l MP-2's calculation No. 96-ENG-01528 E2 Rev. 00; Attachment i A " Conduit Model" provided a correction factor for derating cables in conduits that is applicable for both MP-1 and MP-2.

10 ASSUMPTIOi.i A. Thermo-Lag Installt. tion. l Thermo-Lag was installed so as to provide a 1" fire protective barrier.- In ,
order to maintain the 1" minimal dimension, Thermo-Lag was installed at a l nominal thickness of one and a quarter inches with a tolerance of plus or 3 minus a quarter of an inch. For a worst case scenario, one and a halfinch l thick Thermo-Lag had to be considered in this calculation. l B. Appendix R Cables protected by Thermo-Lag Wrap. !
Most of the cables enclosed by Thermo-Lag that are utilized for Appendix ,
R fire scenarios are normally de-energized and are only energized and carry current during an Appendix R fire scenario. In effect, the derating :
ampacity applied to these cables will only be applicable during an Appendix ;
R ' ire scenario. ,
C. Non-Appendix R Cables / Conduits protected by Thermo-Lag.
In some cases, due to the close proximity of Appendix R conduits to adjacent conduits, the adjacent conduit had to also be wrapped. Cable ampacities of the cables in the adjacent conduits were also included in this calculation.
D. Computer Input Cables.
Cables which supply computer input signals are not considered in this calculation. Since computer input signals are either momentery, or at the milliampere level (no significant 1 R heat loss), an ampacity derating calculation was not performed on these cables. In some configurations, i cables of this nature and their conduits actually become a heat sink to adjacent conduits.
! E. Power and Control Cables that provide power to momentary (providing !
l electrical power for only a few cycles) loads that are enclosed by Thermo-l Lag.
l l
l
, i l
Calc. No 96-ENG-1559 El Page 6 of 1I Cables which supply 125VDC control power to momentary loads are not considered in this calculation. These cables provide control power for operation of 4160 VAC circuit breakers. Circuit breaker operation is a momentary operation, with the circuit breakers operating within a few cycles, thus practically no heat release. The current requirements for circuit breaker operation are low beside only being needed for a few electrical cycles - tripping current is 11.7 amperes, closing current is 6.5 amperes, and breaker elevating current is 7.5 amperes.
Appendix R procedures ONP 525's limits the operation of circuit breakers to one circuit breaker a time. One circuit breaker is operated remotely, while the other circuit breakers are then operated manually one at a time through a kirk-key interlock arrangement. As a result, the heat release given off by these cables is insignificant.
F. Spare Cables. l 1
No derating considerations where made for spare cables. )

lee:
- 1. Identification Df al] locations where Thermo-Lag was installed.
Three locations at Unit 1 are identified where Thermo-Lag was installed, I and for purposes of this calculation will be referred to as " Installations 1, 2, & 3" An overview of the three installations and the functions that the cables enclosed in Thermo-Lag serve is presented in Attachment A, page A-1.
- 2. Identification gcables and conduits al each Installation that are enclosed by Thermo-Lag.
At each installation, section views were prepared that identified all conduits and cables enclosed by Thermo-Lag. Where the relationship between conduits (exiting or entering) changed, a new section view is presented. Physical size relationships between, conduits, enclosed cables, and their Thermo-Lag wraps, were drawn as accurately as possible. This was done to provide a clear visualization of how lightly filled most of the conduits are and to insure all cables enclosed by Thermo-Lag were identified and documented. Section views at each installation are shown in Attachment A, pages A-2 through A-13.

E. Amoacity Correction factor (ACFtsi) for the Thermo-Lag Conduit:
Utilizing test results (base line data) obtained from the testing done by Texas Utilities on Thermo-Lag protected conduits, by means of a calculation Northeast Utilities developed an ampacity correction factor for determing ampacity of cables enclosed by Thermo-Lag that would be site specific. This method is reflected in Unit 2 Calculation No. 96-ENG-01528 E2 Rev.00; Attachment 1 A " Conduit Model" for 1.5" TSI wrap.
l The Ampacity Correction Factor (ACFtsi) determined by the above method L
for 1.5" TSI conduit wrap is 0.771 and is used in Section 6, paragraph C of this calculation.
