Purpose The purpose of this document is to clarify "the'NP-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'lectrical Separation Criteria Ao Definitions 1.,Class 1E Class 1E is the safety classification of the electrical equipment and systems that are essential to emergency reactor

shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise prevent significant release of radioactive material to the environment.

2.

Power Circuits Power circuits provide electrical energy for equipment 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 room and local panels, and logic interlock circuits b

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

c-Annunciator/computer digital, circuits.

d Space heaters including motor heaters.

4.

Instrumentation Circuits Instrumentation circuits are low level analog or digital signals

5.

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

6.

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.

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

a.

Prime Circuits A Non-Class 1E circuit which receives power from a Class 1E source.

The circuit begins at the load side of the source cir-cuit protective device (isolation device),

through the intercon-necting 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 Non-Class 1E circuit which is routed (along any portion of its length) in a raceway with a Class 1E circuit or is contained in an enclosure with Class 1E circuits and physically routed less than 6" from a Class 1E circuit (without an appropriate barrier).

The portion of the proximity circuit which is routed in a Class 1E raceway is termed "Associated By Proximity". If the circuit leaves the Class 1E

raceway, the circuit is termed and treated as NonWlass 1E unless the circuit is also prime (see Figure 4).

8 Redundant For the purposes of this document redundant shall refer to the collection 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 Resi<<

dual Heat Removal System (Low Pressure Coolant Inspection mode) Loop C for the "Reactor Core Cooling" safety function.

9.

Intruding Circuits Intruding circuits are of two types:

1) Class 1E or prime circuits which enter equipment or an enclosure assigned to a redundant Class 1E division, 2) Redundant prime circuits which enter common equipment or enclosures assigned to a Non-Class 1E division; one of these becomes intruding.

For example, Division A prime and Division B prime cir-cuits within a Division A panel requires the Division B prime circuit be treated as an intruder.

Unique Requirements -For-Certain General--Plant Areas 1)

Cable Spreading Room and Cable Chases The minimum separation distance between open trays of redundant Class lE divisions shall be one foot: horizontally and three feet vertically.

The minimum separation distance between conduits and open trays of redundant Class 1E divisions is 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 barr>.ers shall be installed'-Autos'tie dire detection"and suppression must'be piovided oi these areas become General'Plant Areas.

2)

Periphery of PGCC A modular floor raceway system is not provided'in thf.'s-'area.

Cables in this. area shall be routed -in.grounded flexible conduit with 3 feet horizontal separation maintained between redundant Class 1E flexible conduits.

Where this distance cannot be main-

tained, one of the redundant divisions shall be routed in rigid conduit.The-redundant-conduits shall not touch(a'"fire barrier may be used to physically separate the two conduits).

3)

Class 1E Underground Duct System Class 1E equipment located remotely from the plant (e.g.i equip-ment located at the ultimate heat sink) is serviced by divi-sionally separated Class 1E underground duct systems and manholes.

The underground duct system for Class 1E systems is constructed of steel encased in reinforced concrete.

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 laterial raceways.

These raceways interconnect the control panels (which are bolted on the modular floor)"'and tSe termination cabinets.

The network, including transition and extension race-ways, provides separation using vertical and/or horizontal barriers and fire stops.

Miniducts (raceways within raceways) are of similar-construction to the floor raceways and provide separation-withe"We-longitudinal raceways;--Cables-in the mini-ducts are routed in flexible metailic 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 roomr a special set of raceways has been allocated for this use.

The cables and

,an.oraceways.. shall be considered-part, of -PGCC and. therefore are iden-tified the same as those in PGCC ~

Spatial. Separati:on, Within Enclosures andrEquipment -"-.,

s a

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<.

In addition, separated or. isolated..terminal boards and wiring shall.be provided.

When it.-is necessary for a single. device such as a.relay. to be con-nected-.to. wiring from. redundant. Class 1E.divisions, 'the intruding division,wiringshall 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 instrument racks all wiring-between +rminal boxes and the instrumentation shall be routed in flexible metallic conduits.

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 fo3,$ggj.ng requirements..;

r a

4e r

s,,

~ i)t ra a a)

The fail-safe divisions do not provide redundant safety functions to the non-fail-safe divisions except as noted in 2) 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:

~

4

l

.0

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.

2)

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 6 6 cables are assiqned 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 1 raceways/cables/wires require 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, 5g 6i 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 8 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 NMS 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 hot required to comply with Class 1E separation requirements.

e)

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

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.

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.

Circuit breakers tripped by an accident signal are preferable.

However, where Non-Class 1E circuits are helpful to operations personnel following an accident, coor-dinated circuit breakers or fuses actuated by time overcurrent trips shall be used.

Trip characteristics 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.

Zn 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 1E circuits or from Non-Class 1E circuits by devices such as relays, isolation amplifiers, resistors, fuses, circuit

breakers, or current transformers When it is necessary to interface between redundant Class 1E divi-sions, relay coil-to-contact 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 NonWlass 1E portions of the circuit by a fuse, resistor(s),

or an isola-tion amplifier.

Associated Circuit Design Requirements 1 ~

Prime Circuits a ~

Redundant prime circuits shall be physically separated with the same requirements as redundant Class lE circuits (See Section ZZ.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'ircuit shall be separated from a Division B'ircuit and a Division 2 circuit; a Division B'ircuit shall be separated from a Division A'ircuit and Division 1 circuit.

b.

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

b.

A Non-Class lE cable, which is physically not separated from a Class 1E cable within its equipment of origin or destination, but is never routed in a Class 1E raceway, is also assigned with a 9000 series number.

These cables are marked with dual color tags as stated above for a 9000 series cable.

However, such cables are not considered to be "Associated by Proximity".

This is implemented by "Non-divisional (Div. A or Div. B) cable compatibility" in E550/551 cable schedules.

2.a.

Prime cables connect Non-Class 1E loads to Class 1E power sources.

A'1 signifies Div.

In PGCC there are two types of=- routing/cable tagging configurations.

"NSSS" circuits (General Electric scope circuits interfacing with 600 Series panel modules) follow the-cable divisional tagging per column (a) ~

All other circuits (Balance of Plant circuits interfacing with 800 Series panel modules) follow the cable divi-sional tagging per column (b).
