SUMMARY
EVALUATION 1.0 Description The equipment under evaluation is a Raychem WCSF-N Flame-retardant nuclear cable sleeve and S1119 adhesive purcnased under UE8C P.O. No. 9763-006-600-01 for various 3-way and 4-way control and ground cable splicing applications for Class 1E wire systems in the Seabrook Station.
The Raychem WCSF material is also evaluated for flame retardancy by the vertical tray flame testing in compliance with the requirements of IEEE 323-1974 Section 2.5 (Reference 3).
The electrical solices are located in all areas of the plant and are evaluated to the most severe temperature / pressure /
humidity / radiation conditions existing in the plant.
The traceability of the cualification documentation (References 1 and 11) to the WCSF-N caole sleeves and S1119 adhesive supplied by Raychem Corporation under UE&C above P.O. Number is provided by Peferences 4 and 12.
2.0 Conclusion i
This equipment has been cualified by test for sne postulated accident temperature, pressure, humidity and radiation conditions and by test supplemented with analysis for flame retardancy, as well as for thermal aging and operating time.
Therefore, this equipment is qualified to the requirements of NUREG-0588, Category I.
3.0 Limitations 4
None.
4.0 Discussion For UE&C's engineering evaluation of this equipment, see Reference 14

SUMMARY
EVALUATION (continued)
As stated in Reference 5 the WCSF-N has an Activation Energy of 1.35 eV.
Based upon the Arrhenius plot contained in Reference 2, p. 9, A
the Raychem WCSF-N cable sleeve has a thermal life of 40 years at a continuous temperature of 1940F (900C).
This temperature represents the postulated maximum continuous temperature of the spliced conductors and is consistent with the manufacturer's and Seabrook Class IE cable spec!fications.
Twelve test specimens (Reference 1, p. 1) went through.the test sequence indicated in Reference 1, p. 4 Out of these twelve test specimens, Specimen Nos. 1, 2, 3, 7, 8 and 9 were the only ones which were thermally aged (Reference 1, p. 16).
During this aging secuence, Specimen Nos. 2 and 7 were uanble to pass post-environment exposure functional test wnile installed in the test vessel.
They could neither hold the rated voltage and current curing LOCA/MSLB simulation, nor did they pass the Voltage Withstandability (VW) wnile immersed insice the test vessel.
These specimens were retested in a bath of water without the extension leads and all of them passed the above functional tests satisfactorily. Furthe rmo re,
all of the specimens, on a visual examination thereaf ter, were found to be in good order and condition.
Therefore, the failure of test Specimen Nos. 2 and 7 to hold rated voltage and current during LOCA/MSLB test, and their inability to pass the above VW while immersed inside the test vessel, is attributable tc the overaged faulty wires whicn were excluded from the subsequent tests (Reference, pp. 12-14).
From the foregoing, it can be concluded that the anomalies were due to the failure of the faulty extention leads which were non-specimen components in the tests. Since the anomalies are not due to the test specimens, it can be concluded that these anomalies do not affect the qualification of the Raychem WCSF-N cable sleeve.
Therefore, it can be stated that this equipment can meet plant application specific performance requirements.

SUMMARY
EVALUATION (continued)
The qualification of the Raychem WCSF-N cable sleeve is limited to the proper use of this splice within the manufacturer's specified range (Reference 4), and adherence to the in-line splice application (References 9 and 13).
The compatibility of the Raychem WCSF-N cable sleeve and adhesive with the Seabrook Class IE Cables has been verified
>i (Reference 7).
[
These electrical splices are not qualified for use under submerged conditions for cable connections where functional operacility or integrity of the splice is of concern (Reference 8).

i 1.
The thermal life of 40 years was determined using the Arrhenius Plot contained in Reference 2, p. 9.
The conductor continuous temperature is assumed to be 900C (1940F) to be consistent with the manufacturer's and Seabrook Class IE cable specifications.
j 2.
.This equipment was successfully. exposed to a total integrated dose (TID) of gamma radiation which exceeds the combined TID of gamma
. and beta radiation postulated to occur post-DBE inside containment.
However, in accordance with Raychem Corporation Letter VU-40583 dated 10/1/84 addressed to UE&C (Reference 6), 9 i
Raychem product WCSF has a Beta radiation' threshold of 1.0 x 10 7
Rads which envelopes the Seabrook postulated Beta TID of 9.0 x 10 Rads (inside containment,1 year accident dose).
3.
Reference 1, p. 8 states that a solution of 3000 ppm boron as H3 803 was used.
To convert to percent by weight, one must simply take (3000 ppm x 10-0) and multiply this by the ratio of molecular weignt of boric acid to the molecular weight of boron (61.8/10.8) and multiply this figure by 100.
This yields to 1.7% by weight j
which is greater than the Seabrook specified requirement of 1.2%.
4.
The voltage withstand test results at 3.6KV AC (Reference 1, p. 5) is considered as acceptable criteria. Althougn no specific Insulation Resistance (IR) values are indicated in Reference 1-as acceptance criteria, a comparison of the baseline test IR values of i
the test specimens recorded before and after the tests provide the basis for acceptance.
5.
Out of the 12 test specimens (Reference 1, p. 1), Specimen Nos. 1, 2, 3, 7, 8, 9 were the only ones which were thermally aged (Reference 1, p.
16).
Specimen Nos. 2 and 7 were unable to pass post-environment exposure functional test while installed in the' i
test vessel.
They did not hold rated voltage throughout the environmental exposure nor did they pass the voltage withstand test i
while immersed inside the test vessel.- However, investigation to find the cause was conducted after the test vessel was opened. At this point, specimen extension wires were severed inside the vessel t
and the specimens were removed for examination.
The specimens i
unable to pass voltage withstand testing were retested.in a water-bath and again insulation resistance measurements were made. With 4
the extension leads excluded from test, these specimens passe 6 3600 l

Visual examination substantiated the physical integrity of all specimens.
It was concluded that specimens demonstrated the ability to maintain electrical integrity throughout the test program.
From the foregoing, it can be concluded that the anomalies were due to the failure of the extension leads of conductor cable which were non-specimen components in the tests.
Since the anomalies are not due to the test specimens, it can be concluded that these anomalies do not affect the qualification of the Raychem WCSF-N in-line bolted splice assembly. Therefore, it can be stated that this equipment can meet plant application specific performance requi rements.
6.
The initial portion of the postulated profile is not enveloped by the test profile.
However, the peak test temperature exceeds the specified peak temperature by 670F, and the curation of the test time above the plant peak temperature of 3750F is 770 seconds wnich exceeds the plant profile duration of 597 seconds.
Therefore, the test time and temperature is considered to be more severe than the-postulated plant conditions, ano this equipment is expected to perform its safety function when required.
7.
Verification with respect to whether this splice is submerged subsequent to design basis events is completed, based on the information contained in Reference 8.
All electrical equipment, -
concuit, cable trays, etc. found below submergence level have been identified in this report.
It may be noted that this Raychem Electrical Splice Assembly is used only for connection of control and ground cables in junction boxes, and is not intended to be used in cable trays or conduits. A review of Reference 8 shows that there is equipment which is submerged and is not qualified for submergence and is required to be functional or maintain its integrity during postulated accident conditions (Operability Code A or B).
Resolution of the submergence issue for this equipment would also apply to any associated splice. Other equipment which will remain submerged, will not be required to function or have to maintain its integrity during postulated accident events which-causes submergence in that area (designated as Operability Code C).
In view of the above, it can be concluded that these Splicing Assemblies will not be used under submerged conditicas where operability / integrity is required.

SUMMARY
OF CLASS lE ECUIP*ENT SUBMERGED AS A RESULT CF DESIGN 3ASES EVENTS Ecuicment Vaults:
F1 coding in the Equicment Vaults results from a Moderate Energy Line Break (MEL3). The flood elevation is (-)S5'-il" (Reference 1. Taole 3-2).
Class lE equipment located belcw tne flced elevaticn in these areas is ciscussac belcw.
P'unes C3S-7-9A and CSS-P-9B and pressure transmitter C35-PT-2314 are located belcw :ne flood elevation, but are not required for mitigation of tne MEL3 (Reference 2, p.12), and are cesignated in Reference 3 as Oceracility Coce C for the MEL3.
Therefore,.
sucmergence qualification need not be acdressed.
The cable to instruments RH-FIS-610 and RH-FIS-611 has been supplied under P.O. 9753-006-113-17 and is 1ccated below the flood el evatio n.
These instruments will not be sucmerged, but are recuired to mitigate :ne MEL3 (Reference 3).
Therefore..su: mergence-cualification will be accressed for tnis cacle.
The caole ccdes are ADIP anc AD2P for instruments RH-FIS-610 and 611, respectively.
Centainment Building:
The ficed elevation in Containment is (-)20'-8" (Reference 1).
Flooding does not occur in environmental :enes CS-3, CS-11, CS-12 anc CS-13 (Reference 4).
Class IE eculpment locatec below the flood elevation in tnose areas of the Containment Building wnere flooding is postulated to occur is discussed celcw.
Transmitter RC-FT 446 performs no safety function suosequent to a LOCA or MSL3 and is Operacility Coce C for these events (Reference 3).
The equicment listed belcw is installed belcw ficoc level but justifications for not acdressing sucmergence qualification is provicec in RAI 430.62 (Reference 5).

Mechanical Penetration Area:
Flcoding in the Mechanical Penetration Area results frem a liEL3. The ficoa elevation is (-125'-11" (Reference 1, Taole 3-2).
There are three items of Class lE equipment located below fleca level tnat are required to function wnen sucmerged.
They are MM-IR-12, RH-FT-618 and RH-FT-619 (reference 3).
Rack MM-IR-12, i ts accessories, and tne transmittars are not qualified for sucmergence.
Therefore, it i s reccmmenced that tney be relocateo acove flaca level unless it can be snewn tnat operaoility for the MEL3 is not requirea.
i The Class 1E ecuipment listed below is also installed below flood level l
but is designated Oceracility Code C for the MEL3 and need not be qualified for sucmergence ccnditions (Reference 3).

Since tne aoove equipment need not function wnen summerged, tne argument can be-mace that these boxes also need not function wnen su: merged. However, Reference 3 designates this equipment as Co. Coce A for all events.
It is rec:mmendec :nat the operanility coce for tnese boxes be evaluated for change to Cp. C:de C for tne MELS.
The follcwing conduits are located belcw ficed level: HYJ/RA, 4UC/RA, 4UA/RA, 4TZ/RA, HTX/V A, 4TY/RA and 4VM/RA. A review of the UE&C CASP sorting system shows that they carry cacies to RH-V-70, CS-V-142, _
CS-V-162, CS-V-166 and MM-IR-12. A review of the Reference 3 Harsh Envircnment Equipment Li st, snews that only MM-IR-12 must function during tne MELS wnicn causes sucmergence. The caoles associated with this equipment and their purenase orcers and caole coces are shown belcw:

The caole code is MA6R and the purcnase orcer is 113-20 for both caoles. Thi s caole code is alreacy being evaluated for suomergence as it is attacned to the MSD valves listed above.
Cne cable tray runs north to south at elevation 4'-6* in the east pipe cnase. The tray, marxed 86J1YA thru 86RIVA, contains cables wnich ooerate both Class lE and non IE equipment, scme of wnica must operate the event wnica causes flooding.
For example, by using tne UE&C durinforting System, cable FS7/0V7 sucoltes power to instrument CASP i
VB-YT-6822. From Reference 3 it can be determined that this ecut; ment must function curing the HELS wnica causes tne flooding. Therefore, inis caole must function during the event also.- :-ince tnese caoles are in an caen tray and tnere is no separati' n, all caoles in :nis tray are assumed o
to have to remain intact uncer suomergence conciticns.
Therefore,
