I .i j i Raceway Separation Test Program - Discussion of Assumed Failure Modes, Procedure, and Test Results I. Reason For Test Program Limerick has committed to meet the requirements of Regulatory Guide 1.75 as stated in Section 8.1.6.1.14 of the Limerick FSAR. The Regulatory Guide endorses IEEE Standard 384-1974 which allows the use of testing and analysis to justify separation distances less than the standard distances given in the IEEE standard. The Limerick raceway design, which was completed in 1974, was based on the standard separation distances contained in IEEE 384-74. Where lesser separation was required due to physical constraints, tray covers were to be installed. Subsequent additions to the initial raceway design were required to support plant enhancements and Regulatory requirements. Due to physical constraints, some of these additions resulted in lesser separation distances than the standard separation distances contained in IEEE 384-1974. The majority of the cases where the standard raceway separation distances could not be maintained involved separation between enclosed raceway (conduit or gutter) and cable tray. In cases where the standard separation distances between cable trays could not be maintained, the majority of these involved separation between Class 1E cable tray and non-Class lE cable tray. In order to provide justification for these lorser separation distances, Philadelphia Electric Co., in accordance with Section 5.1.1.2 of IEEE 384-1974, completed a raceway separation test program. The test program methodology and results are documented in Wyle Test Report No. 46960-3. II. Description of the Limerick Raceway System The Limerick raceway system design has the following salient features: 1. The raceway system consists of: a) cable tray - open ladder design b) enclosed raceway - conduit and gutter 2. Redundant Class lE cables are routed in redundant Class lE raceway. Non-Class lE cables are routed in Non-Class lE raceway. Non-Class lE cables are not routed within Class lE raceway. Limerick does not have associated circuits either by electrical connection or by proximity. f 4 3. The power sources for cables routed in cable trays or gutters are as follows; a) 480 Vac from load centers to motor control centers b) 480 Vac from motor control centers to 480 Vac loads c) 125/250 Vdc from distribution busses to loads d) Control and instrumentation (120 Vac and lower) 4. The power sources for cables routed in Conduit are as follows; a) 13kV power b) 4.16kV power c) 2.3kV power d) All power sources shown for cable trays and gutter 5. There are very few cases where cables larger, than #4/0 AWG are routed in cable tray. The power sources for cables larger than #4/0 AWG routed in cable tray fall into categories 3a and 3c above. Because cables larger than

1. 4/0 AWG can be subjected to up to 3500A based upon the failure mode assumptions, their failure is expected to have much more severe consequences than the failure of the~ vast

-majority of cables which are #4/0 AWG or smaller and which have power sources in categories 3b and 3d. For this reason, the Limerick raceway separation test program did not test cables larger than #4/0 AWG in cable trays. For those cases in the plant where cables larger than #4/0 AWG are routed in cable tray, the standard separation distances given in IEEE Standard 384-1981 are met or cable tray covers are installed. III. Identification of Failure Modes In order to perform a test program to verify the adequacy of the raceway separation criteria, it was necessary to define the worst case electrical failure that could be postulated to occur internal to a raceway. Previous testing conducted by Philadelphia Electric Company for internal panel control wiring separation (Report No. 48503) showed that the heating. effects of sustained overcurrent en a wire had the greatest impact on adjacent wires. A review of the raceway separation test programs conducted by the industry which postulated high magnitude, short time duration fault currents showed that this type of failure mode had little effect on adjacent cables. The short time duration of this type of failure caused little, or no heating effects on adjacent - cables. We have concluded that the sustained overcurrent condition on a cable has much more impact on cables in adjacent raceway, and a much higher probability of initiating a raceway fire than the high magnitude, short time duration current condition. ., To verify that a cable fault within a tray does not present as limiting a case as the sustained overcurrent failure, we also reviewed our experience with communicating cable faults; that is, the effects of a fault on those cables which are in proximity to the cable failure. Our experience which includes an industry survey shows that for voltages of 13kV and below, cable failures in manholes which cause a failure of adjacent cables are rare. Much of our experience is with distribution voltages of 4kV and 13kV. These voltage levels and their associated high fault currents have a much higher energy capacity to damage adjacent cables than the 480 volt cables contained in the Limerick cable tray system. There have also been several instances at Limerick in which 480V faults have occurred within Motor Control Center Compartments. In all cases, the adjacent control wiring, which was within 9" inches of the fault, was discolored but remained functional. Based on the above experience, we have concluded that cable failures within a cable tray will have less impact on cables in adjacent cable trays than the sustained overcurrent condition which is the basis for our test program. IV. Test Program Assumptions The Limerick raceway separation test program was based on the following failure mode assumptions; 1. The cable or equipment in the circuit develops a fault that is not cleared due to the postulated failure of the primary overcurrent protective device. 2. The fault current level is just below the long-term trip setpoint of the next higher level overcurrent device so that the fault is not cleared. 3. The impedance of the fault adjusts itself automatically to maintain the fault current magnitude at a constant level as the resistance of the wire increases due to i heating, thereby maximizing heat output from the fault cable. 4. There are no other loads on the same circuit which would cause the next higher level overcurrent device to trip. V. Selection of Test Current Level and Cable Size The fault current magnitude of 660A used in the test program was based on the failure mode assumptions discussed above. This assumes that an overcurrent condition occurs on a cable between a 480Vac motor control center and a 480Vac load. The primary overcurrent protective device which is the molded case breaker at the motor control center is assumed to fail to trip. i The next higher level overcurrent device is the load center breaker. The fault current is assumed to be just below the long-term trip setpoint of the load center breaker which is 600A. Since the load center breakers have solid state overcurrent trip devices which have a tolerance of 10%, the j 660A fault current value was selected. This current value t was used for all tests involving cables in cable tray or gutter and was also used for tests involving cables of size

1. 4/0 AWG or smaller in conduit.

In order to select the size cable to be used for tests involving cables routed in tray or gutter, tests were performed to determine which size cable when energized with 660A would deliver the most intense temperature rise for the longest duration to adjacent cables. The Configuration #1 tests of the Test Program showed that the 3/c #2/0 AWG cable was the worst case cable. The Limerick Motor control Centers contain Westinghouse molded case breakers which provide both overload and short circuit protection. The Limerick Load Centers contain I-T-E K600S breakers with solid state trip devices. The solid state trip devices provide increased accuracy and repeatability over conventional trip devices. The load center breakers provide both long and short time overcurrent and instantences short circuit protection. All Load Center and Class IE Motor Control Center breakers are tested on a periodic basis. These breakers are tested and maintained at least once every 60 months, thereby assuring that the probability of two over-current devices in series failing coincidently is extremely small. For cables larger than #4/0'AWG in conduit, the fault current magnitude was selected as 3500A. Thic fault current magnitude is based on an overcurrent condition occurring on a 480 volt feed from a load center to a motor control center given the failure of the load center breaker to operate. Three 1/C 750 Kemil cables were chosen as the fault cables for those tests involving cables routed within conduit and energized with 3500A. This is the largest size cable used inside areas of the plant containing equipment important to l-safety' and based on the magnitude of the fault current' { applied, will generate the most heat. The failure conditions which resulted from the cable sizes and fault currents selected above encompass the conditions i-which can result from failures in categories 4a, b, and c because of the high speed relaying on these systems and the high fault current availability. These features will cause either backup relaying operation or rapid cable failure, thereby preventing long term heat generation. i .....,,_.s ...~. m ..._.m..,.,ms, c.. ,, -...~,, _,, m_ f e VI. Description of Test Procedure The raceway separation test program included testing of the i following raceway configurations: 1) Horizontal cable tray to horizontal cable tray (vertically stacked) 2) Horizontal cable tray to vertical cable tray (riser) 3) Cable tray to gutter 4) Cable tray to conduit 5) Gutter to conduit 6) Conduit to conduit 7) Dropout cable (cable routed in free air) to cable tray 8) Dropout cable to gutter 9) Dropout cable to conduit The procedure used in conducting the tests was as follows; 1) The fault cable was installed in the raceway in the location that would transfer the most heat to an adjacent raceway. 2) The target cables were installed in the adjacent raceway in the worst case position with respect to the fault cable. 3) Pre-test Insulation Resistance and High Potential Tests were performed on the target cables. 4) Target cables were energized with 100 % rated current at 480Vac for the duration of the test. 5) The fault cable was energized with the pre-determined fault current of 660A or 3500A, depending on test i. configuration. 6) The fault cable remained energized with fault current until either the fault cable open-circuited or until the temperature on the adjacent target cables stabilized or decreased. tests with an 7) Post-Test Insulation Resistage acceptance criteria of 1.6x10.n. at 500Vdc and 2200Vac 4 High Potential Tests, each conducted for one minute, f were performed to determine the functionality of the target cables. .../ 8) During the tests, selected temperature readings were recorded on the target cables, fault cable, and raceway. 9) The target cable voltages and currents and the fault cable current were monitored continuously during the test. VII. Test Results i The salient test results with regard to establishing the Limerick raceway separation criteria are as follows: 1) Cables size #4/0 AWG and smaller when energized with 660A and routed in open cable tray did not ignite. Cables were tested in both horizontal and vertical tray configurations and did not ignite in any case. Because the faulted cables did not ignite, configurations with 1" vertical separation between cable trays and zero separation between cable tray and enclosed raceway were tested successfully. These test results provided the bases for the cable tray separation criteria contained in Section 2.0 of Drawing 8031-E-1406. (Attachment 2). 2) The test results showed that no separation was required between an enclosed raceway and another enclosed raceway or cable tray when the enclosed raceway contains cables which are #4/0 or smaller. 3) The test results showed that 1" separation between an enclosed raceway and another enclosed raceway or cable tray is required when the enclosed raceway contains cables larger than #4/0 AWG. The results discussed in 2. and 3. provide the bases for the enclosed raceway separation criteria contained in Section 2.0 of Drawing 8031-E-1406. (Attachment 2). 4) The test results showed that faulted cables routed within conduit will ignite. This result is the basis for the requirement in Section 2.0 of Drawing 8031-E-1406 for sealing conduits which contain power cables. Wyle Test Report #46960-3 completely describes the Raceway Separation Test Program and the results. The Design Analysis transmitted as Attachment 3 provides the analysis and justification for the raceway separation criteria contained in Section 2.0 of 8031-E-1406.

General Separation Criteria 1. Required Separation Electrical equipment and wiring for the engineered safeguard system and the reactor protection system (RPS) are segregated into separated channels / divisions as shown in Tables 7.1-4, 7.1-5, 7.1-6 and 8.1-1, so that no single credible event ( Rev. 15, 12/82 8.1-14 No cuaAAE..

The separation of circuits and equipment is achieved by separate safety class structures, distance, or barriers, or combination thereof. 3. Compatibility with Mechanical Systems The separation of Class 1E circuits and equipment ensures that the required independence is not compromised by the failure of mechanical systems served by the Class IE systems. For example, Class lE circuits are routed and/or protected so that the failure of related mechanical equipment of one redundant system cannot disable Class IE circuits or equipment essential to the operation of the other redundant system (s). 4.

(c) The public address and fire alarm panel that feeds non-Class ~1E loads is fed from a Class IE bus. This panel is not tripped on LOCA, because intentional disconnection of the fire alarm system is a violation of the National Fire Code and is considered unacceptable for plant safety. The' distribution transformer and panel are qualified and seismically supported to i Class 1E criteria. from this panel are run in conduits thatAll circuits originating contain only PA~and fire alarm system wiring. All circuits originating from this panel are protected by thermal magnetic circuit breakers in the panel. In addition, the 440V feed to the transformer is protected by a molded case circuit breaker in the motor control center. Each of these circuit breakers is qualified and purchased as Class 1E; therefore, two Class IE isolation devices exist between the non-Class IE public address and fire alarm circuits and the Class IE 440V bus. (d) Several non-Class 1E drywell cooler fan motors located inside the drywell are fed from a Class IE bus, and the cabling is routed as Class 1E. The non-Class IE RPS/UPS inverters are fed from a Class IE de bus, and the cabling is routed non-Class IE. Two Class 1E circuit breakers are provided for redundant overcurrent protection on each of these circuits. These breakers provide isolation between the non-Class IE load and the Class 1E bus and will be periodically tested in i' Rev. 32, 05/84 8.1-16 1 FS-G1s DRAET ,S. accordance with Technical Specification requirements. These loads are not automatically isolated on a LOCA signal. >^ 5. Non-Class 1E Circuits Non-Class IE circuits are separated from Class IE circuits by the separation requirements specified in Section 8.1.6.1.14.b. Non-Class IE 440 volt loads that are fed from Class IE motor control centers use a shunt trip device on the motor control center breaker to isolate the circuit on a LOCA signal.- These circuits are treated.as non-Class 1E from'~the motor control center to the ~ load and control devices or they are routed as Class 1E only in the division with which they are associated, b.

I (5) Class 1E components of different divisions, but which are not redundant, installed on a common panel are separated by one inch or a flame retardant barrier. Non-Class 1E components are separated by one inch or a flame retardant barrier from Class 1E components. Class 1E components that serve redundant systems are separated by 6 inche retardant barrier, e.g.,,s or a flame ( from core spray B.

Instrument Racks and Panels: j Redundant Class IE instruments and instrument racks are separated so that any design basis event will ( not cause the failure of more than one division of ~ instrumentation needed to mitigate the effects of that event. Physical separation of redundant circuits and devices is provided within each instrument panel as I discussed in paragraph 9 above. 11. Sensors and Sensor-to-Process Connections Redundant Class 1E sensors and their connections to the process system have been sufficiently separated so that the functional capability of the protection system is maintained despite any single design basis event or result therefrom, including the secondary effects of design basis events, such as pipe whip, steam release, radiation, missiles, or flooding. Where practicable, redundant Class 1E sensors and process connecting lines are brought out at widely divergent points, using large components, such as pressure vessels or pipes, as protective barriers. Where necessary, additional barriers are provided to protect.against damage from a credible common cause.
