I. Purpose The purpose of this document is to clarify the WNP-2 electrical separation cri-teria, describe practices used to implement the criteria, and to provide suf-ficient information in a manner to simplify verification of implementation in the field. There are no differences in the design criteria between this docu-

-

ment and the WNP-2 FSAR.

This document should be used by engineers, designers, contractors, QA/QC per-sonnel and operations personnel.

II. Electrical Separation Criteria A. Definitions Class 1E Class lE is the safety classification of the electrical circuits, components, equipment and systems that are essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise prevent signifi-cant release of radioactive material to the environment.

20 Power Cizcuits Power circuits provide electrical energy for component motive power and heating requiring 14.4 kV, 6.9 kV, 4.16 kV, 480 volts, 240 volts, 120/208 V AC, 250 and 125 V DC (see Table I for details) ~

3 ~ Control Circuits Control circuits use 120 V AC (or below) or 125 V DC (or below), and are designed to supply control power for plant systems. The largest control circuit protective device (fuse/breaker) has .a 35 amp rating.

The majority of the control circuits are intermittent in operation'.

Control circuits include the following functions (see Table I for details):

. a. 125 V DC or 120 V AC control to switchgear, control zoom and local panels, and logic interlock circuits.

b. 125 V DC or 120 V AC control power to solenoids.

c. Annunciator/computer digital circuits'.

Space heaters including motor heaters.

Three exceptions to the 35 amp maximum rating exist; two 100 amp circuit breakers and a 60 amp breaker for circuits in the Reactor Protection System and the Reactor Manual Control System. Within the General Plant Areas these circuits are routed separately in rigid conduit. Within PGCC these circuits are routed separately 'n flexible conduits with an attached ground conductor.

4. Instrumentation Circuits Instrumentation circuits are low level analog or digital signals.

5. Low Energy Circuits Low energy circuits are control and instrumentation circuits'.

Isolation Device An isolation device prevents an electrical event in one section of a circuit from causing unacceptable consequences in other sections of the circuit or other circuits.

7. Raceway For the purposes of this document, raceways shall include open or.

enclosed cable trays, flexible and rigid conduit (not EMT) and PGCC modular flooi dupts. Device/component nipples and conduits up to the first tee are not included in this definition but shall be considered as part of the device/component.

8. Associated Circuits Associated circuits are defined as either prime or proximity circuits as follows:

a. Prime Circuits A NonMlass 1E circuit which receives power from a Class 1E source The circuit begins at the load side of the source circuit protective device (isolation device), through the interconnecting .

cables, and up to the final connected load. The portion of a prime circuit which is routed in a Class 1E raceway is addi-tionally termed "Associated By Proximity".

b. Proximity Circuits A proximity circuit is a NonWlass lE circuit which is routed (along any portion of its length) in a raceway with a Class lE circuit or is contained in an enclosure with Class lE circuits and .

physically routed less than 6" from a Class 1E circuit (without barrier) The portion of the proximity circuit which

~ an'ppropriate is routed in a Class 1E raceway is termed "Associated By Proximity". Ef the circuit leaves the Class 1E raceway, the cir-cuit is termed and treated as Non&lass lE unless the circuit is also prime (see Figure 4).

9. Redundant For the purposes of this document redundant, shall refer to the collec-tion of Class 1E circuits, components, equipment, etc. (system(s ) )

performing a specific plant safety function which is a backup to other Class 1E system(s) independently performing the same safety function.

Safety functions, are Emergency Reactor Shutdown, Containment Isolation, Reactor Core Cooling, Containment, and Reactor Heat Removal, and Offsite Radioactive Release prevention. For example, the Low Pressure Core Spray System is redundant to the Residual"Heat Removal System (Low Pressure Coolant injection mode) Loop C for the "Reactor Core Cooling" safety function.

10.'ntruding Circuits Intruding circuits are of two types: 1) Class 1E or prime circuits which enter equipment or an enclosure or an area (either sub-enclosures or as defined by lines of demarcation) of an enclosure assigned to a redundant Class 1E or prime division, 2) Redundant prime circuits which enter common equipment or enclosures assigned to a NonMlass 1E divisions one of these becomes intruding. For example, Division A prime and Division B prime circuits within a Division A panel requires the Division B prime circuit be treated as an intruder.

11 'arrier A barrier is material or a structure placed between redundant Class lE or prime equipment or circuits to limit damage to Class 1E cir-cuits from internally generated fires. Within enclosures and equip-ment barriers are Haveg Siltemp tape or sleeving, conduits (flexible or rigid) and sheet metal enclosures or metal plates. Outside enclo-sures and equipment barriers are solid steel tray covers and bottoms, sheet metal panels, Thermolag insulation, and conduits (flexible in miniducts, PGCC periphery, or where flexibility is necessary, or rigid).

12. Power Generation Control Complex (PGCC)

The PGCC located in the Main Control Room is defined for the purposes of this document as a modular assembly of termination cabinets inter-connected'y floor sections comprised of multiple, separate cable ducts on which are mounted control room panels. ThePGCC forms an interface between the incoming plant cables and control zoom panels.

13. Periphery of PGCC The periphery of the PGCC is defined as the subfloor area between the termination cabinets and the Main Control Room wall.

14. Direct Bridging Direct bridging is defined as a circuit which routes between redun-dant Class 1E raceways (see Figure lA). Direct bridging is prohi-bited'5.

"

Secondary Bridging By Proximity Secondaz'y bridging by proximity is defined as:

a. Bridging of redundant, Class 1E circuits by two (or more) NonMlass 1E (Division A, B, XXX1, XXX2, or XXX3) proximity circuits, routed together in a common enclosure or raceway, and each having part of their routing in a redundant Class 1E raceway (See Figure 1B).

b. Bridging of redundant Class 1E circuits by Non-Class 1E (Division A, B, XXX1, XXX2, or XXX3) proximity circuits within enclosures oz equipment. These proximity circuits may also be extensions of circuits originating from Class 1E raceways (See Figure 1C) ~

,16. Fail>>Safe Systems 2 4 Systems used to shutdown (SCRAM) the reactor are designed to fail-safe upon loss of power(de-energize-to~perate) ~ These systems are the Reactor Protection System (RPS) and those portions of the Neutron Honitoring System (NHS) i.e., Source Range Monitoring (SRH), Inter-mediate Range Monitoring (ZRM), Average Power Range Monitoring (APRM) f, and Local Power Range Monitoring (LPRM) providing input to the RPS.

In addition, system inputs and logic'associated with the containment isolation function are designed to be fail-safe.

17. Equipment and Enclosures For the purposes of this document equipment and enclosures are defined as panels, racks including open faced instrument racks, ter- 2 minal boxes, etc. Individual device/component housings which include the conduit nipple up'to the first tee are not included in this definition-

18. Residing/Compatible Division Wiring Wiring of the same division as that designated for the equipment/enclosure (residing) or is acceptable to be routed with equipment or enclosure residing wires (compatible) ~ All other wiring is intruding.

f B. Class 1E Redundant Circuit Design Requirements Each Class 1E component and interconnecting cabling shall be assigned to one of seven Class lE divisions as noted in Table 'IZ. Class lE components of one division are separated from Class 1E components of other redundant divisions. .Minimum separation distances for trays, conduits, cables, and 2 cables/wires within enclosures are described below. Note that the separa-tion distances specified are to preclude internally generated fire propa-gation between redundant Class 1E divisions and do not consider effects of

'externally generated fires or pipe'reaks and missiles.

1 ~ Spatial Separation Between Raceways a) General Plant Areas (Outside PGCC)

'Distances shown consider the ideal arrangement of two (2) raceways only. If more than two (2) raceways exist in any par-ticular arrangement, physical separation distances chosen must be based on'he complete configuration. Additionally, minimum

'istances are shown assuming that there are .no equipment or materials in that distance that can aid in the propagation of fire.

(1) Minimum horizontal separation requirement between any two redundant Class 1E divisions is 3 feet. This is also appli-cable if one raceway is enclosed and the enclosed raceway is not lower than the open raceway.

b) Unique Requirements For Certain General Plant Areas

1) Cable Spreading Room and Cable Chases The minimum separation distance between open trays of xedun-dant Class 1E divisions shall be one foot horizontally and three feet vertically. The minimum separation distance bet-ween conduits and open trays of redundant Class 1E divisions's one-inch with a barrier provided when the conduit is below or to the side of the open tray and three feet when the conduit is located above the open raceways. Where these distances cannot be maintained, fire barriers shall be installed. Automatic fire detection and suppression must be provided or these ax'eas become General Plant Areas.

2) Periphery of PGCC A modular floor raceway system is not provided in this area.

Cables in this floor area shall be routed in grounded flexible conduit with 3 feet; horizontal separation main-tained between redundant Class 1E flexible conduits. Where this distance cannot be maintained, one of the redundant divisions shall be routed in rigid conduit. The redundant conduits shall not touch (a barrier may be used to physi-cally separate the two conduits ).

3) Class 1E Underground Duct System Class 1E equipment located remotely from the plant (e.g.,

equipment located at the ultimate heat sink) is serviced by divi-sionally separated Class lE underground duct systems and manholes. The underground duct system for Class 1E systems is constructed of steel encased in reinfoxced concrete. The minimum hoxizontal separation between 9

( ~

3) Class 1E:Underground Duct, System (Cont'd) redundant duct banks measured from the bank edges is 18 inches. Redundant duct banks do not crossover. Separation within manholes is provided by barriers.

c) Power Generation Control Complex (PGCC)

Separation is provided by the design of the modular floor in the PGCC. The modular floor is latticed and constructed of steel "I" beams and rectangular steel tubes forming longitudinal and lateral raceways. These raceways interconnect the control panels (which are bolted on the modular floor) and the termination cabi-nets. The network, including transition and extension raceways, 2 provides separation using vertical and/or horizontal barriers and ~

fire stops. Hiniducts (raceways within raceways ) are of similar construction to the floor raceways and provide separation within the longitudinal raceways. Cables in the miniducts are routed in flexible metallic conduit or wrapped with Siltemp tape.

When it is necessary to route cables between PGCC sections which are not directly connected by floor raceways it is permissible to route these cables through the cable spreading room. That por-tion of PGCC cables routed in raceways within the Cable Spreading Room shall be at least identified the same as General Plant Area cables with the interface occuring at the control room floor penetrations.

2. Spatial Separation Within Enclosures and Equipment Where devices of redundant Class 1E systems are mounted in or on the same enclosure or equipment, physical separation (six inches ),

barriers, or isolation devices shall be provided for the intruding devices and wiring. When it is necessary for a single device such as a relay to be connected to wiring from redundant Class 1E divisions, 2

the intruding division wiring shall be routed immediately away from the device to attain the required six-inch separation or to the extent where a barrier can be installed. Within open faced instru-ment- racks all wiring between terminal boxes and the instrumentation shall be routed in flexible metallic conduits.

3. Separation for Fail-Safe Systems Outside of equipment and enclosures,, circuits belonging to fail-safe systems or portions of systems designed to be fail-safe shall meet the following requirements ~

a) The fail-safe divisions do not provide redundant safety functions to Ne non-fail-safe divisions except as noted in 3) below.

Therefore, in general, no separation is required between the non-fail-safe divisions (Div 1, 2, 3) and the fail-safe divisions (Div 4, 5, 6, 7) ~ The following specific criteria applies to fail-safe circuits:

10

't

1) External to PGCC fail-safe circuits shall be routed in grounded conduit (rigid or flex) or totally enclosed raceways carrying only fail-safe cables/wires; the grounded raceways are provided only to preserve the fail-safe nature of these circuits')

Within PGCC fail-'safe circuits shall be routed in grounded flexible metallic conduit carrying only fail-safe circuits and shall be, assigned to raceways as described below

3) Since the Nuclear Steam Supply Shutoff System logic out-puts control Divisions 1 and 2 valves and PGCC contains no Division 4, 5, 6, or 7 raceways it is necessary to route the fail-safe cables with non-fail-safe cables.

Hense, Divisions 4 a 6 cables are assigned compatibility with Division 1, and Divisions 5 6 7 with Division 2.

These Divisions are compatible in General Plant Areas as well as in PGCC.

Considering the above, Division raceways/cables/wires require 1

no separation from Divisions 4 or 6 raceways/cables/wires; Division 2 raceways/cables/wires require no separation from Divisions 5 or 7 raceways/cables/wires. Divisions 4 and 6 shall be separated from Division'2 and Divisions 5 and 7 shall be separated from Division 1. Divisions 4, 5, 6, or 7 need not be separated from Division 3 except to preclude direct bridging bet-ween redundant Class 1E raceways.

b) RPS SCRAM Solenoid Cabling Wires from both RPS trip system trip actuators to a single group of SCRAM solenoids are permitted to route in a single conduit. A single conduit shall not contain wires to more than one group of SCRAM solenoids Wiring for the A and B solenoids for the same control rod can run in the same conduit. See Figure 2.

c) NMS and Main Steam Line Cabling Cables routed through the containment penetrations are grouped so that failure of all cabling in a single penetration cannot pre-vent a SCRAM. This applies specifically to the NHS and main steam line inboard isolation valve position switch cables. See Figures 2 and 3.

d) RPS Power Supplies Power supplies to systems which de-energize to operate require only that separation which is deemed prudent, to ensure reliable operation. Therefore, the RPS motor generator sets output cabling are not required to comply with Class 1E separation requirements.

e) Four Division Separation Wiring for the four RPS SCRAM group outputs and the NMS LPRH inputs shall be routed as four separate divisions See Table XV and XVI 'and Figure 2.

11

f) The NMS ling in the area immediately un neath the reactor need not be completely routed in enclosed raceways nor separated in accordance with Section ZI.B.la due to space limitations and the need for cable flexibility.

g) Class 1E logic inputs to the RPS and Containment Isolation System from main steam turbine process and status sensing instrumen-tation (Load Rejection or, Turbine Trip), Turbine Generator Building leak detection and Main Steam Tunnel high radiation instrumentation, their associated instrument racks, cabling and raceways are located in the Turbine Generator. Building. This equipment, even though located in a non-seismic Category I struc-ture, shall be mounted to seismic Category I requirements and all related cabling routed to Class 1E requirements'.

Separation Within Divisions ln order to preserve functional integrity and to meet single failure criteria the MSLCS, the SGTS, and the RRCS contain certain system portions (RRC and MSLCS isolation valves/controls and.the SGTS discharge dampers/controls) that require separation within a single division. In these instances separation shall be maintained between the redundant portions as though the portions were in redundant divi-sions or an analysis shall be performed to show that lesser separa-tion is acceptable.

5. Raceway, Cable, Equipment, and Enclosure Identif ication V

a) Class 1E cables routed within conduits need not be identified within the conduit.

b) Cla'ss lE General Plant. raceways shall be uniquely identified with a color coded marker every 15 feet, at the beginning, end, at pull boxes, and discontinuities (walls, structures, etc.) as shown in Table ZZI.

c) Class 1E cables routed in Division 1 through 7 raceways in General Plant Areas shall be uniquely identified with a color coded marker every 15 feet and at their terminations as shown in Table IIZ except as noted in ZZ ~ B.1.C. These markers shall be provided on the cables up to the first termination within equip-ment and enclosures.

d) Class 1E cables routed in PGCC raceways shall be uniquely iden-tified with a color coded marker every 5 feet near the cable divisional marker as shown in Table V. These markers are pro-vided on the cables up to the first termination within equipment and enclosures. PGCC longitudinal raceways shall be identified with a color coded marker at approximately 5 foot intervals as shown on Dwg. E775. Each lateral raceway shall be identified at the longitudinal raceway lip centered above the lateral raceway.

e) Conduits in the periphery of the PGCC floor area are identified by metal tags which identify the cable number and division.

Since these tags are not color coded, an additional color-coded marker shall be attached near the metal tag to identify the con-duit divisional assignment.

f) Within enclosures and equipment Class lE intruder circuits shall be uniquely identified with a color coded marker at 12 + 2 inch intervals as shown in Table VZI.

12

g) Circuits that have been upgraded from NonClass 1E to Class 1E and are already installed in raceways shall be identified with a Class 1E color coded marker at terminations, pull boxes, and entrances and exits to raceways. Upgraded cables shall be routed in Class 1E raceways. Cable installation records shall be reviewed to provide assurance that these cables are routed in Class 1E raceways and installed to Class 1E requirements (cable installation parameters). Otherwise, megger and continuity tests shall be performed, termination and routing reinspected to Class 1E requirements, and documentation prepared verifying the upgrade.

h) To differentiate between cables and wires where tracing cables inside- equipment and enclosures is difficult, color coded wire markers are utilized as shown in Table VI.

i) Equipment and enclosures shall be uniquely identified with two color coded markersr one marker with the identification number and a second with the assigned separation division of the residing components, cables, and wires. These markers shall be ~

color coded as shown in Tables III, IV and V- Individual com-ponents located on or in equipment and enclosures require iden-tification markers only and are not necessarily color coded, but need not have individual divisional separation markers. For example, an instrument rack shall be uniquely identified with a color coded identification marker and a divisional separation marker. However, each separate instrument need not have a color coded identification marker or a divisional separation marker."

Open faced racks which contain components from more than one division shall be provided with appropriate divisional separation marker on each division terminal box The identification number marker for multidivisional equipment and enclosures shall be black lettering with a white background.

Single equipment and enclosures containing cables, wires, and/or devices of redundant divisions shall be provided with color coded divisional separation markers utilizing at least one of the following methods:

1. Equipment or enclosures containing intruding wires/cables/

devices may be identified by a residing division separation marker and all intruders identified and separated as such.

2. Equipment and enclosures containing an area(s ) or bay(s )

dedicated to intruding wires/cables/devices with 6" separa-tion (or barrier) from residing/compatible wires/cables/

devices may be identified with the residing division separa-tion marker. The intruder area, which may be enclosed par-tially or entirely by metal barriers, may be identified by an intruding division separation marker placed either within lines Of demarcation or on the separation barrier. Intruding wires/cables/devices within these areas need not be iden-tified as intruders.

I \

p j), Within open faced instrument racks wiring from terminal boxes to individual instruments is routed in flexible conduits. These conduits need not be identified with a cable identification number or with a divisional separation marker.

k) Two different equipment, enclosure, and cable identification schemes exist within PGCC; one for those provided within the General Electric NSSS scope and the other for those provided within the Balance of Plant scope Refer to Tables V, XZZZ, XZV, XV for details of these schemes. Those BOP PGCC cables that route directly between BOP and NSSS panels shall be identified using the NSSS designation scheme but, with BOP system designations 6 Transient Data Acquisition System (TDAS )

The TDAS is a Non-Class 1E, computer based, data collection and reduction system which receives the majority of its inputs from Class 1E systems. The system shall be designed as, follows:

a. All TDAS input. circuits within raceways shall be identifie'd and routed to Class 1E requirements up to a remote isolation device.

From the isolation device to the remote multiplexer the circuits are considered to be Non-Class 1E.

b. Remote multiplexer outputs are transmitted to the computer via a fiber optic cable which is inherently an isolation device. The fiber optic cable, therefore, can be routed in any raceway without regard to separation criteria.

c. TDAS Class 1E input isolators are supplied from Non-Class 1E 24VDC current limiting power supplies. The power source to these power supplies is Class 1E and provided with a Class 1E current interrupting device. The circuit to the power supply shall be routed as prime for Division and 2 isolators and as Class 1E 1

for the Division 3 isolators The power supply at the isolator is internally isolated from the Class 1E signal input circuit."

Downstream of the power supply, the circuits shall be treated as Non-Class 1E.,

7. General Plant/PGCC Interface For the purposes of cable identification General Plant, Area cabling entering the PGCC interfaces with PGCC cabling at termination modules within the termination cabinets. This cabling shall be designed to the divisional compatibilities and designations as shown in Tables XIII and XIV.

8. Isolation Devices Where circuit isolation devices are required, consideration shall be given to types of devices available and the type of circuit protec-tion required.

14

Isolation device types shall 'be applied as follows:

a) Class 1E power circuits shall be isolated from Non-Class 1E circuit faults by devices which provide adequate circuit interrupting capability. Class 1E circuit breakers tripped by an 2 accident signal are preferable; all circuits downstream of except the accident tripping portion of the trip circuit the'reaker, itself, shall be considered Non-Class 1E. However, where NonClass 1E. circuits are helpful to operations personnel following an accident, coordinated circuit breakers or fuses actuated by time overcurrent trips shall be used. Trip charac-teristics shall be such that for all faults the downstream device will interrupt current prior to trip of any upstream breaker or fuse. Various combinations of fuses and circuit breakers may be used.

In addition to current interrupting devices, current limiting devices may be used either alone or in conjunction with interrupting devices to isolate power circuits Current limiting

~

shall be accomplished by using current limiting or isolation transformers.

b) Low energy Class 1E circuits shall be isolated from redundant low energy Class lE circuits by devices such as relays or isolation amplifiers. Low energy Class 1E circuits shall be isolated from non-Class 1E loads by resistors, fuses, circuit breakers, or current and potential transformers.

When it is necessary to interface between redundant Class 1E divi-sions, relay coil-tomontact isolation is acceptable. That is, the coil of the relay may be powered from one division and the relay contacts can be used for interface with a redundant division.

The contacts shall not be used in more than one redundant divi-sion circuit since this condition would be contact-to-contact separation which is not acceptable-Class 1E instrumentation circuits may be isolated from Non-Class 1E portions of the circuit by a fuse, resistor(s), or an isola-tion amplifier.

Associated Circuit Design Requirements Prime Circuits

a. Redundant prime circuits shall be physically separated with the same requirements as redundant Class 1E circuits (See Section II.B) from the load side of the source circuit protective device to the final connected load except as noted in c. below. For example, a Division A prime (A ') circuit shall be separated from 2 a Division B prime (B') circuit and a Division 2 circuit; a Division B prime (B ') circuit shall be separated from a Division A prime (A ') circuit and Division 1 circuit.

b. Class 1E power sources shall be protected from failures within prime circuits by a Class lE isolation device.

15

~ c

) c. Deviations to prime circuit separation criteria implementation are as follows:,

1) Circuits downstream of Class 1E isolation devices (circuit breakers) which are tripped by an accident signal shall be "treated as Non-Class 1E and not. as prime.

2) . Emergency lighting, obstruction U.ghting, main control room normal lighting, sync circuits, SLCS, meteorlogical tower supervisory, fire protection circuits, and the, UPS Inverters (IN-1 and ZN-4) shall be provided with two series Class 1E isolation devices (circuit breakers/fuses ) Downstream of

~

the second isolation device the circuit shall be treated as.

Non-Class 1E and not as prime.

3) A single circuit supplies power to the Technical Support Center (TSC) ~ This circuit shall be routed as prime to the Motor Contxol Center located in the TSC. Downstream of the MCC feeder breakers the circuits shall be treated as Non-Class 1E and not as prime.

4) Circuits supplying power to the 24VDC power sources for the Transient Data Acquisition System remote multiplexers and the General Electric scope Regulatory Guide 1 '7 displays shall be routed as prime from the Class 1E isolation device (circuit breaker) to the current limiting 120VAC/24VDC power supply. Downstream of this power supply the circuits shall be treated as NonWlass 1E and not as prime.

5) Circuits supplying power to other Regulatory Guide 1. 47 displays from the Division 1 and 2 24VDC batteries shall be treated as NonMlass lE and not as prime.

P

6) The Non-class 1E TDAS inverter input power circuit from the Class 1E 480 VAC supply shall be treated as prime to the inverter. Downstream of the inverter the output circuits shall be treated as Non-Class 1E and not as prime.

2. Proximity Circuits Proximity circuits when routed in a Class 1E race~ay ("Associated by Proximity" ) shall meet the same physical separation criteria as that applied to the Class 1E circuits as follows.

a. Routing criteria for proximity circuits are as shown in Tables X, XI, and XII external to PGCC and Table XZV within PGCC Proximity circuits may also be prime circuits'efer to Section IZ.C-1 for prime circuit separation criteria.

b. Proximity circuit sections routed in NonMlass 1E raceways shall be treated as Non-Class 1E and have no specific separation cri-teria applied except as described in Sections II.B.1.a.5 and ZI.C.1 (See Figure 4) ~

16

P ~ ~

~ ~

I c. Within equipment or enclosures, no specific separation criteria is applied to proximity circuits unless they are also prime cir-cui ts ~

Effective April 1, 1983 each proximity circuit routed in Class 1E raceways and not protected by a Class 1E circuit protective device (fuse, circuit breaker) shall be analyzed to demonstrate that its failure and effect on Class 1E circuits cannot result in loss of abi-lity to safely shutdown the plant. Such cables that do effect safe plant shutdown shall be assigned alternate raceway routes.

d Bridging Circuits

1) Class 1E circuits, prime circuits, and proximity circuits, as shown in Figure lA shall not bridge between redundant Class 1E raceways'esign control to alert designers of a potential for cable direct bridging is provided by Note 4 in' the computerized cable schedule (BsR Drawings E550 and E551). Refer to Table XIV, Examples 1 through 4.

2) Secondary bridging within Class 1E equipment or enclosures is allowed for low energy circuits as shown in Figure 1C.

3) Secondary bridging by proximity circuits is allowed to occur within NonMlass lE or Non-Divisional raceways as shown in Figure 1B. It is acceptable to route Divisions A, B, XXX1, XXX2, and XXX3 cables together in the same PGCC Non-Divisional raceway.

Note 4 of the computerized cable schedule is assigned to any Non-Class 1E cable with the potential to become a direct bridge.

This occurs when this cabl'e is routed in a Class 1E raceway and has a continuing section routed in a Non-Class 1E raceway. For example, Note 4 would be applied to a Division B cable routed in a Division B raceway and subsequently routed into a Division 1 2.

PGCC raceway; potentially this cable, external to PGCC, could be routed into a Division B raceway and then into a Division 2" raceway creating a direct bridge.

3. Prime and Proximity Circuit Identification a~ Prime cables routed in Divi,sion A and B raceways in General Plant Areas shall be uniquely identified with a color coded marker every 15 feet as shown in Table IV except as follows:

1) Prime cables routed in conduit need not be uniquely iden-tified with the color coded marker.

2) Enclosed and open raceways shall be identified every 15 feet, at discontinuities, at pull boxes, and at end points with the appropriate prime color coded marker except as

'oted in II C 3.f.

~ ~ ~

3) Cables that have been upgraded from Non-Class 1E to prime and are already physically installed in plant raceways shall not be retrofitted with the prime color coded marker except at all terminations, pull points, and entrances and exits to raceways.

b. Prime cables routed in PGCC raceways shall be uniquely identified with a color coded marker every 5 feet near the cable divisional marker as shown in Table V except as follows:

Circuits that have been upgraded from NonMlass 1E to prime and are already'physically installed in the PGCC raceways shall be identified with the prime color coded marker only at entrances and exits to PGCC raceways and at terminations within enclosures.

c. Within Class 1E enclosures and equipment intruding prime circuits shall be identified the same as Class 1E intruding circuits as in IZ.B.5.f above. I 2,

d. Within NonMlass 1E multi-divisional enclosures and equipment assigned to either Division A, B, XXX1, or XXX2, an intruding prime circuit shall be uniquely identified as in II.B.S.f above.

e. Proximity circuits shall have a unique color coded marker as described in Table ZV.

f. Raceways which contain prime and proximity cables with a Di.vision 1 through 7 compatibility shall be identified with the appropriate divisional separation marker (Division 1 through 7) l2 even if these raceways route to Non-Class 1E enclosures or equip-ment. Raceways routing prime cables and identified with Division 1 thru 7 separation markers require no prime checkered markers. Z.

Prime cables routed in these raceways shall be identified with prime checkered markers except as noted in II.C.3.a.3.

Do NON-CLASS 1 E CIRCUIT DESIGN REQUIREMENTS Non-essential circuits or portions of circuits, which are not prime or "Associated By'Proximity" are termed and treated as Non-Class 1E. Refer also to Figure 4. Electrical separation criteria shall not apply to Non-Class 1E circuits except as noted in Il.B.l.a.5 or below for utility power circuits. Non-Class 1E circuits shall be assigned to NonMlass 1E divisions as shown in Table XZV. Non-Class 1E raceways need not be physi-cally separated from each other or from any Class 1E raceways unless they contain power circuits. Deviations to standard divisional assignments are as follows:

Digital computer signals in the reactor building are routed in Class 1E divisional raceways as applicable by the device being served.

NonWlass 1E digital signals in other areas are routed in instrumen-tation raceways of Division B irrespective of the diviszon by which the device is being served.

l ~

~ I ~

2. Analog computer signals in the reactor building are routed in Class 1E divisional raceways as applicable by the device being served.

Non-Class lE analog signals in other areas are routed in instrumen-tation raceways of Division A.

Non-Class 1E Division A and B raceways, excepting conduits, do not exist within the Reactor Building or the Cable Spreading Room. This requires that most NonWlass 1E cables be routed in Class 1E raceways; these cables become "Associated by Proximity" ~ Division,A and B conduits routed within these areas are designated with separation markers as shown in Table IV.

Zf cables within these conduits have a Division or 2 "compatibility" 1

then the separation markers shall be in accordance with Class 1E require-ments (see Section IZ.B.4).

Within PGCC, raceways are designated Division 1, 2, 3, or Non-Divisional.

No Division A or B raceways exist. Thus, Division A and B cables shall be assigned to Division and 2, respectively, and/or to a Non-Divisional 1

raceway.

Within Class lE Main Control Room panels Non-Class 1E utility power cir-cuits shall be separated by 6" or a barrier from all other wiring.

Non-Class 1E circuits need not be uniquely identified inside enclosures or equipment except for wizes downstream of the first termination as shown in 2 Table VZ NonWlass 1E cables routed in open raceways shall be uniquely identified as described in Table ZV. NonClass 1E cables shall be tagged with color coded markers at their terminations, pull points, entrances and exits to raceways, and every 100 feet. Division A and B raceways are tagged every 100 feet, at discontinuities, entrances and exits to rooms, pull boxes, and end points.

Non-Class 1E cables routed in PGCC raceways shall be uniquely identified with a cable I.D. marker every 10 feet and with a color coded cable separation marker every 5 feet as shown in Table V The Non-Class lE cables which wholly route in compatible Non-Class 1E raceways (Div. A or Div. B) are routed in accordance with cable routing criteria stated in Tables X, XZ and XIZ. Division markers for equipment/raceways and cables are color coded per Table IV.

III. Criteria Implementation The purpose of this section is to assist the desi.gn engineer in the implemen-tation of the design criteria. The principal elements for design consideration include:

Device service requirement, Provi.ding an appropriate power supply based on device service requirements, Assigning the cables to meet device/power source compatibility, Routing of the cables in raceways to meet the separation criteria requirements, and Enclosure/equipment/raceway/cable identification.

The following details explain the steps to be followed to assure proper imple-mentation of the criteria.

A. Class 1E Circuits Class 1E systems are listed in Table ZI.

All Class 1E electrical equipment and enclosures are tagged with an iden-tification number. In addition, a di.vision identification marker is provided which indicates the assignment to one of seven divisions (Divisions 1, 2, 3, 4, 5, 6, and 7). This division marker is inscribed with color coded characters using the color scheme shown in Table ZII for all equipment external to PGCC and per Tables V, XIII, and XZV for equipment internal to PGCC including control room panels.

All devices required to VIZIER power sources of the compatible division as shown in Table Loop A is supplied from the Division 1 Class 1E power source.

II'or preserve Class lE functions are supplied from Class example, 1E RHR The assignment of a proper cable number is key to the implementation of separa-tion criteria. Each cable number is guided by Class 1E division designation, the equipment of origin, and the circuit/cable identificati.on number. The metho-dology of cable number assignment and the significance of various characters are provided in Table In addition to the unique identification number, each cable is also identified with a divisional marker as shown in Tables ZZZ, V, XIII and XIV.

Routing criter'ia for Class 1E cables in General Plant Area raceways is provided ,

in Tables X, XI and XZI. Table XIII provides the routing requirements inside the PGCC raceways. As indicated in these tables, routing of Class 1E cables in non-compatible division raceways or Non-Class lE raceways is not permitted.

Divisionalized raceways are designed to meet the criteria requirements as stated in Section ZZ.B.1. The raceway identification scheme is provided in Tables IZZ and V.

20

E II

~ I ~ I ~

Class lE equipment and enclosures are identified with an appropriate divisional marker to show the residing Class 1E division of the internal cables and wires.

Zntruder cixcuits are identified with a color coded max'ker in accordance with Table VII 'ote that Table VZZ identifies cix'cuits. as intruders which are not described as such by the literal definition of intruder (refer to ZZ.A.10) 2 i.e., for ease of design criteria implementation'ot all those circuits iden-tified as intruders are Class 1E or prime.

Class 1E cables may contain non-Class 1E circuit.conductoxs. These cables shall be identified as Class 1E.

B. Prime Circuits Prime circuits are identified on the cable schedules by a A '1 or B '2 designation in the "SPTY CLR" field. See Table ZX Column 14 for details. A '1 signifies' cable that connects a Class 1E Division 1 power source to a Non-Class 1E Division A device. Similarly B'2 signifies a cable that connects a Division 2 power source to a Division B device.

A Division 1 power source is never connected to a Division B device via a Similarly," a Division 2 power source is never connected to a Division B'able.

A device via an A'able.

All prime cables and the Non-Class 1E divisional raceways in which they route, in addition to the Non-Class 1E'identification markers, are identified with a checkered marker as described in Tables ZV and V.

A '1 and B '2 circuits are not routed in the same raceway. The separation requirements for the prime cables in enclosures. is the same as that for the Class 1E cables as shown in Table VIZ.

Within PGCC prime circuits are required to be routed in Class 1E compatible divisional raceways as shown in Table XZV.

C. 'on-Class 1E Circuits NonWlass 1E circuits such as Turbine Generator, plant service circuits, etc.

are assigned to either Division A or Division B. As described in Section ZI D, Non-Class 1E raceways for routing of Non-Class 1E cables do not exist in all plant areas. Therefore, certain Non-Class 1E cables (prefixed with A or B) are required to be routed in Class 1E raceway systems. Such cables axe treated as "Associated by Proximity" and are divisionally marked as shown in Tables IV and Vo Within PGCC, Division A, Division B, XXX1, 2 and 3 Non-Class 1E circuits axe allowed to be xouted together in a Non-Divisional xaceway. Precautions must be taken to assure that these circuits do not cause direct bridging. Refer to Table XIV for further discussion.

- Typical Tray Compatibility C1 Typical Tray Compatibility CA Detail 1 illustrates the treatment of a proximity cable with sections routed in both Class 1E and Non-Class 1E raceways Due to the programming limitation of the computerized cable schedule, such a cable is treated in two sections. The section routed in the Class 1E raceway is assigned a type, a divisional com-patibility, and an AXXX 9000 series number in the cable schedule. This entry (see Table IX, Column (2)) is developed as shown in Table VZZZ, Item (2) ~ The cable destination is called out to be TP - an imaginary Transition Point - with a note that the cable continues to be identified with a consecutive number.

Refer to Table ZX, Column (4) for details. The portion of the cable which is routed in a NonWlass 1E raceway has type/cable compatibility noted in Column 2 of Table ZX. This section of the cable is assigned a consecutive cable number.

The 9000 series cable as described above are color coded as shown in Table IV.

Note that both consecutive cable numbers appear along the entire, length of the cable in the Class 1E as well as the Non-Class lE raceways.

Do Non-Class 1E, Non-Divisional Circuits There are certain systems such as the security system, fire protection/

lighting, communications etc. which are not assigned to a division. These cables are routed either in dedicated conduits or they are assigned a Non-Class lE divisional circuit identification and routed in appropriate raceways.

Eo General Plant/PGCC Interface The requirements of General Plant/PGCC interface are shown in Table XIII and XZV. GE NSSS circuit design is based on the general details provided in Tables XV and XVI.

'(OTES'he equipment and enclosure divisional marker determines the comoatible division of the residing (unmarked) wiring and cabling. For example a "DIVA" equi marker indicates that the following cable "SEPN" types are "Division A Compatible" XXXI,~SA , ~C xxXI, XXXII, xxxIII, sA, cA, sB, cB. All internal panel wiring which is not identified by individual separation markers is considered "Division 1 Compatible" wiring.

Non-Class IE cables are routed in Non- Divisional raceways.

Cable separation categories enclosed by a 'box such as ~~x x indicate prime cables.

APPENDIX A FIELD VERIFICATION I

The purpose of this Appendix is to provide a more simple and condensed form of the criteria in a manner to assist in field verification. This Appendix is not as comprehensive as Section ZZ and related tables and figures, but is intended to be a verification tool capable of addressing the large ma)ority of installations in the field.

For Contractor personnel, if during the course of construction first or in-process inspec-consult Section ZZ tion activities deviations from this Appendix are found, w'hich is more complete and/or request clarification from supervisory personnel. If a deviation still exists, the specific(s) should be brought to the attention of"Burns and Roe through normal project means.

Zt should be noted that this Appendix was principally written with assistance from

-Bechtel QC and Bechtel Engineering personnel to input: a construction perspective. Zt.'s recognized that there is duplication between this Appendix and the remainder of the document. This Appendix has been reviewed by Burns and Roe and determined to be consistent with the other sections. Zt has been incorporated into the Burns and Roe document to provide a single place for a baseline for WNP-2 electrical separation.

A. General

1. The Appendix describes criteria for three areas; General Plant including Cable Spreading Room, Control Room and equipment and enclosure internal circuits.

2. The typical raceway and cable markers used in all plant areas are as follows:

a. Raceway Marker (1) External to PGCC Tray ~ H Div 2 Div 2 - Raceway Division Rigid Conduit Di.v 2 Orange H - Raceway Type, High Voltage in this case (used outside of PGCC only)

• Flexible conduit requires a metal tag with the separation colors in bands.

• >> Service type letter (P-, C-, H-, S-, R-) is provided for trays only (typical).

+ When a Non-Class 1E Div A cable (outside PGCC) is tagged XXXII or SB/CB (inside PGCC), and is routed in Div 2 raceways inside PGCC, then it will have reference note 4 (in E551/E550) and is not allowed to route into Division 1 raceways external to PGCC. Similarly for a Non-Class lE, Div B cable (outside PGCC).

When a Non-Class lE XXXI/SA/CA cable (inside PGCC) is tagged Div B (outside PGCC) and is routed in Div 2 raceways outside PGCC, then a reference note will be added to the PGCC schedules to not allow this cable to route into Division 1 raceways inside the PGCC. Similarly for Non-Class 1E, XXXIII/XXXII/SB/CBcables (inside PGCC)

C1 These markers are for PGCC panels including all PGCC termination cabinets >the non-divisional PGCC raceway markers are white with no lettering while the non-divisional cable separation markers have background colors as indicated but have no lettering.

C. Control Room Area

1. The following separation requirements apply to raceways in the Control Room Area.

a PGCC (1) PGCC raceways are formed of modular floor sections. No specific

'separation distances apply except that the raceways of redundant Class 1E divisions are to be separated by steel barriers which may be part of the PGCC floor modules. The separation between Class lE divisions .and non&ivisional raceways within the PGCC shall be by using firestops to prevent an air channel between redundant Class 1E divisional raceways.

(2) Hiniducts within the longitudinal raceways also serve as divi-sional raceways. The cables in the miniducts are enclosed in flexible metallic conduit or Siltemp tape.

Ig D. Equipment and Enclosure Znternal Circuits

1. The following separation requirements apply to redundant Class 1E and prime devices, cables and wires ~ The redundant division circuit, which is not the residing equipment:/enclosure division, is the intruder cir-Cuito

a. A minimum of 6" physical separation is required

b. Where 6" separation cannot be achieved, barriers are required conduit or Siltemp tape for wiring and metal enclosures e.g.,'lexible for devices.

c., When a common device (relay) is used by design to terminate wiring of, two redundant Class lE divisions, the intruding division wiring is to be routed immediately away from the device to attain the required separation or until a barrier can be installed.

d. Non-Class 1E utility circuits are to be separated by 6" or a barrier

~

from all other circuits within Hain Control Room panels.

e. Some examples of separation inside equipment and enclosures are shown in Sketches A, B and C.

2. Within equipment and enclosures, cables and wires with the following color coded markers are compatible and may be routed together. Cables and wires with markers other than those shown below are to be separated as in D.1 above and marked as intruder circuits per this Appendix, table A-3.

3. Outside PGCC equipment and enclosure residing division separation markers are located on the front. Equipment and enclosures mounted on PGCC have the separation markers located inside the rear door, on barrier. (covers), or within lines of demarcation.
