- a. Space inside the termination compartment is not sufficient to permit the use of two-hole lugs,
- b. Equipment is supplied with pigtails having vendor installed one-hole lugs,
- c. Two-hole lugs are not available from the vendor, or d .' Vendor equipment is supplied with contacts intended c for use with one-hole lugs.
NOTE: At Sequoyah, generally, AMP terminal lugs and butt splices are used for wire size No.10 and smaller and Thomas and Betts f terminal lugs and butt splices are used' for wire sizes No. 8 AWG and larger.
- Terminal lugs and butt splices for conductor size No. 8 AWG and larger shall be of the uninsulated type. For conductor size No.
- 10 AWG and smaller, terminal lugs and butt splices should be uninsulated in applications where the use of Raychem heat shrink-able sleeving is a requirement. In splicing applications where Raychem heat shrinkable sleeving is required to insulate the spliced connection or where acceptable for .use inside primary con-
,. tainment (see Section 2.2.3.1) only lugs and splices preinsulated with Tefzel or Kynar may be used. Outside primary containment, preinsulated lugs and splices may be vinyl, nylon, Tefzel, or Kynar.
Terminal lugs and butt splices shall be selected using
.i manufacturer data and installed with tooling approved by that manufacturer for use with his product. The tools shall contain f
die stops to prevent overcrimping and a rachet-type feature I
(where applicable) to prevent undercrimping. Guidelines for
- appropriate tool & die selections for various, wire sizes are 4
given in Appendix A and Tables B-1, B-2, and B-3 of Appendix B for terminal and butt splice accessories from Thomas & Betts, AMP Product Corp. ,' and Burndy Corp. , respectively.

2.2.l.2 To minimize output errors, selection of terminals and-
~
butt splices for terminations at thermocouple extension wires shall be based upon the following:
/~ a. For iron-constantan and copper-constantan thermo-L couples, tin-plated copper terminal lugs and butt
" splice connections shall be used. However, to ensure that both legs remain at approximately the same temperature, the legs of the thermocouple shall be lashed together after insulating the
, terminations. This may be accomplished by the l
use of a cable tie, a short piece or heat shrinkable sleeving, or by taping. -(If the legs of the thermocouple do not remain at approximately the same temperature, an error may result in the output.)
- b. For chromel-alumel thermocouples, chromet and aiumes terminal lugs and butt splice connectors are .
preferred and shall be installed with the arriopriate crimping tool. The chromel lug or connector shall
'be installed on the chromel extension wire and the alumel lug or connector on thelal' umel extension wi re.
(These types of material- tend to be brittle .mi acr subject to fracture. After installation, immediatety verify that the lug or connector has not been t ractured.)
Tin-plated copper terminal lugs and butt spiire connectors may also be used as long as both legs F of the thermocouple are lashed together after insulating the terminations as discussed in 2.2.1.2a above.
I 2.2.1.3 Use of fasteners (bolts, nuts, washers, etc.) wnich meet a specific ASTM specification or have a particular thread type or size to connect the conductors to the component is not required as long as the fasteners used will permit torquing, where applicable, as prescribed in M&AI-9.
All fasteners used on a particular termination shall ,
be of the same material and shall be compatinle with the material of the device terminals. This may oe accomplished, for example, by using brass fasteners on copper or copper-alloy terminals. Unless otherwise' prohibited or contrary to Food construction practices, the same connection may be made using steel fasteners which have been plated or suitably treated to be corrosion resistant.

3.0 INSTALLATION 3.1 Terminating and Splicing 3.1.1 General Instructions i
I 3.1.1.1
- Cleanliness is of great importance in making any: splice-
' or termination. The electrician's hands should be clean, particularly when applying the tapes and/or Raychem, and every reasonable precaution should be taken to exclude dirt and moisture wh'le the work is in process.
In a hot environment, sweat bands around the elec-trician's wrists will tend to prevent perspiration from accumulating on the hands. Use of sweat bands is recommended.
NOTE: Terminating, splicing, or repairing of damaged cables methods which are dependent upon the type of environment (MILD or HARSH); field may refer-ence the 47E235 series to determine what areas-in the plant have been designated to be considered MILD or HARSH environments as necessary.
~
3.1.1.2 Field to ensure that all equipment and crimp tools used in terminations ~and splices are done with cali-brated equipment in ~accordance with AI-31 prior to performance of work and that related CSSC tool numbers and calibration due dates are recorded on applicable ,
data sheets. This includes crimping tools, meggers, V0M's, torque wrenches and screwdrivers, etc. Also l
prior to performance of terminations and splices field '
to ensure related cables to be terminated or spliced are'(1) deenergized, (2) verify work will not adversely affect any operational circuits, (3) be aware of any energized circuits near their respective work area and exercise appropriate amount of caution, (4) verify all train / channel separation and identification requirements
. are adhered to per related design drawings. ,

SQNP M&AI-7 Page 15 of 45 Revision 8 3.0 INSTALLATION (continued) 3.1.1.3 Enlarging holes axi terminal lugs or mismatching stud and terminal lug hole size is no longer permissible, unless terminal lugs with the proper size holes are not available from the vendor. Terminal lugs shall F
be selected with holes which are compatible with the size of fasteners or stud size required by the tenminals on the device. Requests for deviations from this policy should be submitted to OE for evaluation on a case-by-case basis. To minimize the corrosion potential due to the protective coating being removed when holes are enlarged, a liberal application of Thomas and Betts' Kopr-Shield (or equivalent) shall be applied to the mating surfaces and bolts of terminal lugs, or the terminal lug shall be retinned.
,- 3.1.1.4 Manufacturer's instructions are to be followed in the-installation of cable accessories, such as terminal lugs. Where initial crimping is questionable, recrimping of terminal lugs is acceptable (unless otherwise pro-hibited by the vendor of the lug) if the following conditions are met: ,
- a. The orientation of the recrimp shall be the same as that of the original crimp.
- b. The recrimping shall be done with a crimping tool which is properly calibrated.
- c. Each recrimped terminal shall be compared with a sample which has been. installed with a properly calibrated tool. If the terminal lug installation compares favorable, then the recrimped terminal .
- lug is considered acceptable. LIf the comparison is unfavorable, then the recrimped terminal shall be cut off and a new terminal lug shall be installed.
3.1.1.5 Raychem type N heat shrinkable products shall be used to insulate all splices and terminations in harsh environments for Class IE category A and B equipment (Appendix E of NUREG 0588) and certain non-Class 1E equipment whose failure due to postulated environmenu.i conditions could prevent the satisfactory accomplishment
- of safety functions by safety-related equipment [10CFR;n.

3.1.1.6 Field to ensure that drawings to be used for inspection
~
are TVA EN DES issued or TVA EN DES approved vendor drawings. On electrical items for which a TVA EN DES drawing is issued, this drawing shall be used for inspection purposes. If the "endor has contractual
' obligations to maintain and turnish TVA EN DES approved vendor drawings for a particular system or piece (s) of equipment, the approved vendor's drawings shall be used. However, when both the EN DES issued and the EN DES approved vendor's drawings are available, the EN DES issued drawings shall take precendence. Any discrepancies between the TVA EN DES issued or TVA EN DES approved vendor drawing (s) shall be corrected to agree via the means of an FCR which will be initiated by the cognizant engineer. Also the inspector shall record-the drawing (s) and the revision (s) used for the inspection on the appropriate data sheet (s).
It is generally accepted that a termination is the point
~
3.1.1.7 where the end of the wire is layed down or where it is connected to the end device (i.e. motors, solenoid valves, terminal blocks, etc.). Splices are normally
- the point where cable or conductors form a union or junction (i.e. cable penetrations) and continue to the end device. However, it should be noted that terminations aay not necessarily only be accomplished via terminal lugs or splicing solely by butt splices and throughout this procedure terminal lugs and butt splices may both appear in the termination and splicing sections randomly.

Definition: Thermoplastics - Materials which soften when heated, and become firm on cooling-vinyl and' polyethylene are examples. Thermoplastics can be repeatedly reshaped by alternate heating
- ,. and cooling.
Thermosets - Materials which harden or set when heat is applied. The application of heat is called " curing." After curing these plastics cannotbereshapegandareinsolubleinmost solvents. Kapton Type F film is a typical example, ,Dupont Trademark.
3.1.2.1 Terminations of conductors shall generally be accom-plished by means of enclosed (ring or rectangular) tongue terminal lugs crimped :nto the wires by means of appropriate tools (see Section 2.2.1). Exceptions to
' this method are noted in Section 3.1.2.5. Where the terminal lug being used is furnished with a sight hole
' or open barrel, the strands of the conductor shall be visible beyond the crimp, but shall not extend beyond the barrel so as to interfere with the seating of the fastener. Exceptions to this method are noted in Section 3.1.2.5.
NOTE: Because of differences between tools and terminals of the listed manufacturers, it is important to i.
follow the manufacturer's instructions applicable to the specific installation being made. Terminals of a company shall always be installed with a tool purchased from or certified by that company to:-
) ensure a uniform pressure crimp.
3.1.2.2 Either uninsulated or preinsulated terminal lugs (see
- ' Section 2.2.1) may be installed in systems of 600V or less and wire sizes No. 10 AWG and smaller. Preinsu-lated terminals having a wire insulation grip shall be barrel of the terminal to give some protection against electrical faults and accidental contact with live terminals, or where mechanical stress from vibration
' or flexure at the point of application might be required.
.' Preinsulated terminals within the primary ' containment shall be either Tefzel (Thomas & Betts Company) or Kynar (AMP Special Industries). The vinyl or nylon preinsulated fittings are intended for applications where the total temperature of the conductor does not i
~ exceed 105 C (221 F).

Case (2): If the shield is not to be terminated,
~
it shall be cut off near to vnere insulation was stripped back per the
'- above and insulated. Inside containment or harsh environments a Raychem WCSF-N sleeve, .;r equivalent, shall be used to insulate the area where the shield and l' other conductors have the outer insula-tion and cable jacket removed for termi-nation purposes (for either case 1 or 2) by over-lapping the sleeve off the outer cable jacket onto the area where the cables fan out for termination. Outside l~ containment or in mild environments the l afore mentioned method may be used or field may use an equivalent substitute for insulation such as taping or a commercial grade of shrinkable tubing.
3.1.6 General Guidelines for Splicing 3.1.6.1 Cable splices shall be made where:
(1) The circuit length exceeds the full standard-cable reel length.
(2) The allowable cable pulling tension will be exceeded.
(3) Specified on design drawings and/or cable schedules of the design project.
(4) The cable insulation or conductor has been damaged (unless it can be repaired per Section 6.0).
(5) The point oE termination must be extended because of design change or incorrect termination prior to checkout.
3.1.6.2 Criteria for splicing: *
(1) Splices shall be made in boxes or enclosures when located in seismic category I structures (except as noted in 2 and 3). This requirement is also recommended in non-category I structures unless otherwise noted on design drawings. (Refer to SQA
- 134 for list of Category I structures as required).
For splicing of cable (s) installed in cable trays field may use SD-E12.5.9. (See Attachment II for
, SD-E12.5.9) 6 .
- - - . -~-.-,, -
SQNP M&AI-7 Page 25 of 45 Revision 8 3.0 INSTALLATION (continued) 3.1.6.2 (continued)
(2) In conduit banks, splices may be made in the cable trays located in manholes. In conduit banks containing handholes, splices may be made directly in the handhole.
(3) In cable trenches, splices may be made directly in the cable trench.
(4) Cables shall be supported so there is no mechanical l
load on the splice.
(5) The splices shall be arranged to' avoid physical buildup at any one point. Staggering of splices is recommended but not required. The combined area of the spliced conductors shall not exceed the application diameter range of the Raychem WCSF-N overall sleeve. (refer to SD-E12.5.6).
(6) Each spliced circuit shall have a permanent identi-fication tag containing its unique designation per cable schedule or pull card installed adjacent to the completed splice and if possible WP or MR/WR number should be listed also. Refer to electrical standard drawing SD-E15.3.4.
(7) The field shall document on cable termination /
splice data sheet and cable pull cards where splices have been made. This documentation shall be detailed enough to readily locate the splice by specifying splice elevation, distance from column lines, or azimuth and radius as applicable.
Also related contract and cable reel no.(s) shall also be recorded on cable pull cards for splices.
NOTE: Cognizant engineer should add M&AI-4 and -6
- data sheet (s) in WP's or WR/MR's as necessary when splicing for documentation purposes of the addition of a new length of cable or conduit.
Cables in the 480V and medium voltage (5-15kV) shall not be spliced inside the cable spreading room.
SQNP M&AI-7 Page 26 of 45 Revision 8 3.0 INSTALLATION (continued) 3.1.6.3 Splicing guidelines at Electrical Penetrations-For locations, connections, and voltage levels on electrical penetrations field should refer to 45N860-3/45A860-series for Unit 1 and 45N870-3/45A870-series for Unit 2. Also for electrical penetrations 1 through 4 (6900V), see
" Installation Instructions for Westinghouse Electronic Tube Division" and the memorandum from F. W. Chandler to R. M. Pierce (SQN 127A and WBN 127A). On splices made at the electrical penetrations it is recommended that six to eighteen inches of slack should be lef t in the spliced cables and that no cutoff or minimum-tare cut off should be made on the leads from the penetration.
It is also advisable that the field should megger and make continuity checks on penetration leads prior to making splices.
l 3.1.7 Thermoplastic or Thermosetting-Type Insulations-Splicing (600V or less) 3.1.7.1 Splicing of conductors shall generally be accomplished by means of enclosed (ring or rectangular) tongue
, terminal lugs or butt splices crimped onto the wires by means of appropriate tools (see Section 2.2.1). Excep-tions to this method are noted in Section 3.1.7.3.
Terminals and splices of a campany shall always be installed with a tool purchased from or certified by that company and it is important to follow the manu-facturer's instructions applicable to the specific installation being made to ensure a carefully controlled uniform pressure crimp.

3.2 Minimum Bending Radius
, 3.2.1 ' General Information For a detailed discussion of Minimum Bending Radius, see M&AI-4 and/or DS-E12.1.5.
[' Definition--The Minimum Training Radius (MTR) is the smallest l radius to which the inside surface of the cable or conductor may be bent after all pulling operations have been completed.
3.2.2 Calculations and Requirements I ,
In making terminations and splices, the MTR of the cables and/or conductors must be considered.as follows:
- 1. The MTR for single conductors is equal to the appropriate
', installation factor (I fc the cable outside diamefer) (OD). in Table 1 of DS-E12.1.5 times MTR = I
. fac
- OD eable
~' , 2. For multiconductor cables the minimum training radius as followa:
MTR = I
- fac
- OD eable However, in terminations and splicing of the multi-conductors, the outer jacket is normally removed to allow for the installation of the terminal lugs and/
, or butt splices. Therefore:
HTR = OD
- conductor fac NOTE: If necesssary, the cognizant engineer shall coordinate with OE in obtaining relaxed values t / of the MTR.
For multiconductor or single conductor terminations /
splices covered with a Raychem sleeve the MTR should ,
be based on 5 times the new OD of the splice but shall not exceed the MTR value of the cable or individual conductor. It is recommended, where feasible, that the termination / spliced connection not be bent.

7.0 INTRODUCTION
TO RAYCHEM HEAT SHRINKABLE PRODUCTS Raychem.WCSF is a heat shrinkable, flame retarded flexible polyolefin tubing which is especially formulated and tested to withstand the particular environment found in light water reactor nuclear generating stations. It may be supplied in either " coated" or " uncoated" foon.
When coated, the suffix "N" is added to the part designator to indicate that the entire inner surface of.the tubing is covered with an adhesive which is designed to form an environmental seal under normal, off-normal and design basis event (DBE) conditions. Uncoated tubings carry the suffix "U".
I WCSF is rated to 1000 volts. The tubings have been tested and qualified to a 40-year service life at 90*C continuous operating temperature.
' Qualification - Raychem has performed environmental qualification type testing with WCSF-N tubing-in accordance with the guidelines of IEEE Std. 323-1974 and IEEE Std. 383-1974 to qualify WCSF-N for use on Class IE electrical systems within the containment of nuclear generating systems.
Raychem qualification type tests are valid when the tubing is used .
in accordance with the guidelines and the application ranges included in this document. -Use of the product outside the published use ranges may invalidate the applicability of the qualification tests.
The qualification status of Raychem nuclear products is conditional on the substrate materials being capable of maintaining physical and seal integrity under the same conditions to which the Raychem materials are qualified. It is also required that the cable substrates to which Raychem products are applied be clean and degreased a'nd be suitable-sealing surfaces (e.g., woven jackets or. braids are unacceptable' as sealing surfaces in the splice area).
7.1 Selection of Tubing 4
7.1.1 General Requirements Selection of tubing must first be based on whether it is
_ intended for use inside containment, where DBE environmental parameters apply, or outside containment, where no accident environmental performance is required. Tubing application ranges are most restrictive inside containment to ensure qualification for LOCA/MSLB environments. '
7.1.2 Tubing Application Range Determine the diameters 'of both wires to be spliced and the dimensions of the splice hardware to be used. When splicing multi-conductor cable it is important to obtain measurements of both the individual conductors and the outer cable jacket diameters.

7.0 INTRODUCTION
Tr RACYCHEM HEAT SHRINKABLE PRODUCTS (continued) 7.1.2 (continued)
Refer'to applicable electrical standard drawing (s) to determine the applicable use range
- of the Raychem Product i
needed to accomodate the splice diameters. (i.e., SD-E12.5.6 Type N Heat Shrinkable Cable Sleeves. Table A - inside containment or Table B - outside containment applications).
Generally, select the largest size tubing from applicable range table which accomodates the splice diameters. The ranges of Type N tubing on SD-E12.5.6 should also be used when sizing Type U tubing for splices and/or terminations.
t Generally, use a 3 inch nominal overlap onto the wires to assure a 2 inch minimum seal length. This allows for longitudinal shrinkage and positioning error. The 2 inch minimum seal. length shall be required for all terminations /
splices unless specified on design drawing and/or notes.
For seal lengths less than the 2 inch minimum the cognizant engineer shall coordinate these special cases through OE. ,
For braided type jackets it is allowable to overlap the N
outer sleeve approximately 1/4 inch (from the primary insulation 2 inch minimum installation) in order to hold the braided jacket in place or a separate piece may be used. Since this piece is for cosmetic type purpases either type N or U sleeving may be used.
USE RANGE is defined as the range of substrate diameters over which the tubing.is intended for use.
.2 NOTE: WCSF-050N is a thin wall tubing for use as a shim or small wire jacketing; not as primary insulation.
~
7.1.3 Cable Preparation .
All Raychem shrinkable products are designed to be used on smooth, clean substrates. Glass, asbestos, or similar braids must be removed to. allow a coated part to perform its sealing function. When multiconductor cable jackets are removed, all binders, tapes and fillers should be trimmed back to the jacket.
Af ter making connections, . sharp edges, or protruding wire strands shall be removed using abrasive cloth (i.e., 120 grit aluminum oxide cloth) or by a file.
Reelean or degrease as required.

caps require less heat for shrinking. Position breakout or end cap on cable as required. (1) shrink breakouts at the junction of the legs and body. After the legs are recovered shrink the body portion. (2) shrink end caps, beginning with the closed end and work towards the open end.

7.0 INTRODUCTION
T0 RACYCHEM HEAT SHRINKABLE PRODUCTS (continued) 7.1.4.4 Shims - When substrate diameters vary greater than the
, use range for a single tubing, shims are used to build
, up the diameter of one or both wires to within the use
,1 range of the termination / splice insulating sleeve. It is necessary to assure that all tubing is used'within s its recommended use range. Reference SD-E12.5.6 (NOTE 12),
i
, Table A or B and/or SD-E12.5.7-1 Tables E and/or H.
Normally the entire length of the shim must be applied to a suitable sealing surface to maintain a 2 inch minimum seal length; however, an exception to this case arises (see SD-E12.5.8) where in some cases a shim may be required to build up individual conductors in order 1
to meet the use range of the breakout's legs or body.
,; NOTE: If it becomes necessary-to shim the individual conductor of.a multi-conductor cable for the i
installation of a cable breakout's legs or body, the minimma length of the shim should be equal to the length of the breakout's leg or body. In this case shims length use may vary but should t'
extend out from the breakout legs or body by.1/4 inch minimum. The outer tubing (i.e. overall outer sleeve) should mmpletely cover and overlap
,, the shim by a minimum of 1/4 inch.
NOTE: The formula for calculating the new outside 2
~ diameter of the substrate Dod=VD.d+K(i.e.when calculating shims) does not accound for adhesive thickness. An allowance of (.005 .010 inches) may be added to the new cable ouside diameter to
, account for the applied adhesive thickness. Also
, for calculation of the effective diameter, (Deff),
,. over a bolted connection for proper sleeve and/or
. shim selection see SD-E12.5.7.1 (Note 16).
DO NOT FLEX newly installed Raychem components until comfortable to touch.
It is recommended that in ambient temperatures below 40'F to preheat the splice / termination
- area until it is warm to touch prior to install-d ation of tubing.

7.0 INTRODUCTION
TO RAYCHEM HEAT SHR1LKABLE PRODUCTS (continued) 7.2 . Inspection of Installation and Acceptance Criteria Raychem heat shrinkable products shall be used on all Class IE
,)
terminations / splices except as noted on design drawings including electrical standard drawings, this instruction, or in approved WP instructions. Tubing and/or other components shall be positioned
, and installed per the above.
i p? Tubing and/or other components are " fully recovered" when both of the J', following criteria are met: (1) Outer surface is smooth and has a glossy appearance, (2) There is a visible flow of adhesive ~at each end of the tubing and/or other components (when using nuclear grade coated components).
NOTE: Uncoated components should generally conform to the I substrates contour. Overheating of the tubing must be avoided. This evidenced by scorching or blistering on
, i the surface. Any minor surface scorching that can be removed by' solvent cleaning is acceptable. Tubing with deep blistering shall be replaced.
L WCSF tubing and components which have a lumpy appearance not l conforming to the substrate or has a dull surface has not
,' been heated sufficiently. Under heating can be corrected at any time by reheating and continuing the shrinking process.
7.3 Removal of Installed Tubing and Components
~
WCSF tubing and components which are found to be incorrectly installed (i.e. improper location over splice or termination,
' wrong size tubing, scorched, blistered, etc) may be removed by lightly scoring the outer cover and reheating. The Raychem
,. tubing or component will shrink itself into and may be removed by use of channel locks or equivalent non-cutting tool. This o
is to prevent the electrician's hands or fingers from becoming burnt.
g.,
,' CAUTION: When scoring the outer cover of the Raychem tubing or component field to ensure the cable jacket, connector, or conductor (s) are not damaged.

- TBMIS head when using 15500 die series catalog numbers requires a die
- adapter No. 15500.
- Not available NOTE p/
The cast lugs listed above are factory marked for use with the 40-ton hydraulic head; therefore, the use of TBM15 hydraulic head would r'equire t twice the number of compression op-rations on large size lugs for proper w
termination due to the smaller ccmpression area of the 15-ton dies. Lugs ,
for the 350- to 500-MCM and 600- to 750-MCM copper wire ranges employ die
' codes for 99H and 112H, respectively, for the 15-ton head which are half-size. khenever possible all Thomas and Betts Company's series 53000 cast copper terminals above 300 MCM should be compressed with a 40-ton head.

This instruction contains the procedure for completing the electrical
- (, connections for the incore thermocouples including installation of the
~
extension wire connector.
NOTE:
r-All insulation resistance (IR) measurements shall be made using an ohameter capable of measuring resistance up to 10 10 ohms with a maximum applied voltage of 100 10V dc.
- 2. Check all extension wire connections for proper polarity and workmanship.
I Extension wire is to be in accordance with W Specification Sheet 195A785.
- 3. Slide a 3" piece'of WCSF-115-N onto the extension wire. Install extension wire connector (see Figure 1). Apply LOCKTITE 271 to the screw threads to prevent loosening. Remove all traces of epoxy from the blade surfaces.
I NOTE: Do not attempt to terminate the extension wire shield inside the colinector. The shield must be terminated'(ungrounded) outside the connector. '
p
- 4. Shrink the heat shrink into place per Figure 1. Slide a 3-1/2" piece of RNF 100 and 3-1/2" piece of WCSF-200-N heat shrink onto the extension wire.
-5.
' Connect thermocouple connector to the corresponding extension wire pair, verifying continuity to the corresponding reference junction terminals in the process. Measure and record IR (with extension wires s disconnected from reference junction terminals).
IR must be greater than 1.9 x lo ohms at 100 volts. Verify results and signoff-inspection on Attachment III, Data Sheet 1.
- 6. Shrink the heat shrink into place per Figure 1, signoff Raychem Installation on Attachment III,-Data Sheet 1.
