Davis-Besse Unit 1 Fire Hazard Analysis Report NOTES FOR APPENDIX C-3 C3-17 FHAR Rev 28 9/2018
- 1.
Component is required for Safe Shutdown. The values represent the fuse size or frame size/long-time delay pickup setting of the trip device. See notes on Drawing E-4 for typical applications of power sensor (type PS1-A) overcurrent trip devices on bus incoming and tie breakers. Type SST overcurrent trip devises with internal ground fault protection are provided on certain feeder breakers.
- 2.
Within a family of protective devices, the most limiting are the highest 116 rated load (downstream) device and the lowest rated supply (upstream) device. Less limiting devices are bounded by these devices, and therefore the less limiting devices are normally not evaluated directly.
- 3.
Process rack, relay and control cabinet loads are individually fused and coordinated with the incoming breaker/fuse. Where the cabinet provides power for solenoids, individual coordinated fuses serve each branch circuit. Fuse sized and types were taken from the design and vendor drawings and the fuse list. Where a specific type was not listed or verified by walkdown, the most conservative type of those stocked by Davis-Besse for the application was assumed.
- 4.
Procedures require stripping loads prior to backfeed, therefore, associated circuits will be verified to be tripped/disconnected prior to energizing the backfeed path.
- 5.
See Fire Hazard Analysis Report (FHAR Appendix A Note 5; this component acts as a power supply and the connected load cables are routed to evaluate spurious actuation due to hot shorts, however, coordination of the individual loads is not required since power to this component is not needed for Safe Shutdown.
- 6.
Evaluated for associated circuit coordination.
- 7.
This power supply is Daisy-chained with a Safe Shutdown component. Therefore, coordination is required to ensure operability of the Safe Shutdown component. For example, a typical circuit feeds three panels off a 10-amp fuse. Only one is considered Safe Shutdown, but all three cables are associated with the safe Shutdown component and routed in FHAR Appendix B. The largest fuse on the other two non-Safe Shutdown relay cabinets is evaluated to ensure that a short there blows the fuse at the non-Safe Shutdown panel instead of the 10-amp fuse.
- 8.
GENERAL NOTE: Due to implementation of FCR 85-0063, the 480V level has been adequately coordinated for Safe Shutdown; see the 480V Breaker Coordination to Meet Common Power Source Criteria of Appendix R (Calculation C-EE-013.10-001). Cables associated with breakers that will have the automatic trip function removed are listed in Appendix C-3 are protected by the upstream breakers.
A fault in the feeder to the Jockey Fire Pump (MP0060) due to a fire in Area BH will trip BE1280 considering the cable length to the fault; this provides adequate coordination.
Yes indicates adequate coordination for Appendix R. No indicates that the Safe Shutdown Analysis assumes loss of the power source. ACC means that a lack of coordination is acceptable and is considered in the Safe Shutdown Analysis. An entry of
Davis-Besse Unit 1 Fire Hazard Analysis Report NOTES FOR APPENDIX C-3 C3-18 FHAR Rev 28 9/2018 NA in the Load column indicates that a single fuse is provided for the entire scheme listed.
- 9.
Unbuffered AC does not leave this cabinet; therefore, coordination is not required beyond the feeder breaker.
- 10.
Number not used.
- 11.
Containment Emergency Sump Valve is depowered for Safe Shutdown.
- 12.
Circuits 1CY104A & B (2CY204A & B) provide 120V AC control power to the Control Room Emergency Ventilation System Panels C6708 & C6714 (C6715 & C6709) from panels Y1 (Y2).
A review of E-801, Rev. 12, E-60B, Sht 37, Rev. 3, E-60B, Sht 34, Rev. 3, and Vendor Drawings 7749-M-410-550-7, 7749-M-551-7 and 7749-M-410-281-10 shows that all circuits powered from Y1 and Y2 are Safe Shutdown cables except for 1LV4906A(2LV4907) which are buffered low level instrument cables. A short circuit or induced voltage on the low level instrument cables will not affect Safe Shutdown.
The power serves redundant equipment in Fire Area HH and control circuits routed in common areas DD and FF; otherwise, redundant Trains of CREVS are not routed in the same fire area. A lack of coordination within a Train due to a fire in the above specific areas could result in a loss of CREVS, but this is already assumed in the analysis. The fuses at Y1, Y2 are adequately coordinated with the incoming fuse.
Therefore, there are no associated circuits of concern and the lack of coordination does not affect Safe Shutdown.
- 13.
Y1(Y2) and alternate feeds Y3(Y4) supply control power to the respective emergency diesel generator cabinets as follows:
C3615 E-559 Sht 1, Rev 10 C3616 E-560 Sht 1, Rev 9 E-559 Sht 2, Rev 9 E-560 Sht 2, Rev 11 C3617 E-559 Sht 3, Rev 13 C3618 E-560 Sht 3, Rev 13 C3621 E-559 Sht 4, Rev 13 C3622 E-560 Sht 4, Rev 13 Y1 & Y4 are used as the control power sources due to coordination concerns.
To evaluate the circuits associated with the diesels, the conservative approach was taken to review all cables to and from the cabinets as shown on the above wiring diagrams.
- a.
Safe Shutdown cables have been evaluated separately.
- b.
Cables that interconnect the above cabinets are all local to the respective diesel (same fire area) and, therefore, could not become an associated circuit of concern (e.g. Scheme GD107 and 111).
Davis-Besse Unit 1 Fire Hazard Analysis Report NOTES FOR APPENDIX C-3 C3-19 FHAR Rev 28 9/2018
- c.
The Day Tank level instrument is separately powered from C5758C (M-324-41-18 Sht. 2) and is not an associated circuit of concern. Channel B is similar.
- d.
Circuits with Channel A or B designators are not powered from Y1 or Y2
[annunciator circuits, computer inputs to Drawing E-724, isolated relay contacts (e.g. E-64B Sht. 1B, Rev. 8)].
- e.
Cables ACV1131B and G (EL4B SW 11B, Rev. E) are powered from Y1 and the cable is routed to the intake structure however the 2 amp fuse adequately coordinates the whole scheme with the upstream fuse of the same type and does not jeopardize safe shutdown circuits (E64B Sht. 11B, Rev. 12).
- f.
Diesel sequence schemes SXSEQ 1-4 are powered from a different ACC supply at relay cabinets (E64B Sht. 18, Rev. 2), SFSEQ 1-4 are powered from SFAS (E64B Sht. 17, Rev. 5) and are not considered Safe Shutdown for Appendix R.
- g.
Diesel warning light Schemes BWLDG 1 and 2 are powered from Relay Cabinets (Ch. A, B) (E-64B Sht. 19, Rev. 0), not Y1/Y2.
- h.
SFAS Remote Position Switch Monitoring SFC11 (E760) is not powered from Y1/Y2.
Each circuit feeds the cabinets for a single diesel generator. Circuits stay in the fire are associated with the respective diesel generator (e.g. 6A feed to relays) except for separately fused (2A) indicating lights which are adequately coordinated. By the above process of elimination, there are no associated circuits of concern and a lack of coordination does not affect Safe Shutdown.
- 14.
The circuit feeds the Remote Shutdown Panel (C3630). Individual power supplies buffer (isolate) those low level instrument cables that leave the area. The fuses are only subject to fire-induced fault current if the fire occurs in Fire Area R. Safe Shutdown is possible without these circuits. See Drawing 7749-M-544-6-10. (For transfer of DC circuits see E-45B Sht. 11B, Rev. 15). Therefore, these are not associated circuits of concern.
- 15.
The circuit feeds the SG high point vent valves (AC), position indication and alarm relays. Power is not required for Safe Shutdown. A blown fuse will not prevent Safe Shutdown (See E-1009, Rev. 4, E-1010, Rev. 4, E-1050 Shts. 1 and 2, Rev. 1, E-1051 Shts. 1 and 2, Rev. 1, and E-52B Sht. 71B, Rev. 1). Therefore, these are not considered circuits of concern.
- 16.
CDF-11A-1 provides status indicating lights for CF01B and RC3704 provides control power to CCWS surge Tank Level Relay LR3757. Power to these components is not needed for Safe Shutdown although the power cables are individually evaluated in each area analysis. RC3706 is a spare circuit. CDE-11B-2 provides control power for normally de-energized DH12 Interlock (E52B/24D, Rev. 8). RC3702 provides power for
Davis-Besse Unit 1 Fire Hazard Analysis Report NOTES FOR APPENDIX C-3 C3-20 FHAR Rev 28 9/2018 the SG level set, and diesel sequence schemes, neither of which is required for Safe Shutdown.
CDF-11A-1 and CDF-11A-2 share a common power source, however, power is not required for Safe Shutdown. The Circuit 1CY117B for RC3706 is a spare and therefore, is acceptable. CDF-11A-1 provides indication for CF01A which is not needed for Safe Shutdown and CDF-11A-2 is similarly fused and no longer provides indication for the M.S. Isolation Valves FV101D and E. Therefore, these are not considered associated circuits of concern.

Power to SFRCS Cabinets C5762A and C5792 is not required for Safe Shutdown. Any failure mode of logic or relays is acceptable for the Appendix R Safe Shutdown Evaluation. See also Note 18 for indicating lights. Therefore, these are not associated circuits of concern. With a Loss Of Offsite Power (LOOP), Buses YE2 and YF2 will be without power for approximately 10 seconds until the EDG is loaded and during this time SFRCS logic channels 3 and 4 will be tripped. See System Description SD-010 Rev. 0, Section 2.7 for a discussion of logic and solenoid power sources and distribution. Either the incoming circuit breaker or the breaker feeding the loads provides acceptable coordination.
- 18.
Power to the Main Control Room and local indicating lights is individually fused and is not required for Safe Shutdown. Physical positions and component operation can be verified if necessary (E-576 Sht. 6, Rev. 16, E-568 Sht. 7, Rev. 18). Therefore, there are no associated circuits of concern.
- 19.
This circuit feeds a single system (NI/RPS) in the Control Room. Within C5755E, a 5-amp fuse feeds RY indicators including the source range channels NI-NI1 and 2 (M-563-317, M-536-37-5). In addition, this power source feeds the power supplies for the source range and power range detectors and the RPS inputs: (7749-M-536-12-12)
Reactor Building Pressure Reactor Trip Reactor Pressure Linear Bridge The NI Source Range Cables (E-730/Sh. 3, Rev. 4, E-731/Sh. 3, Rev. 4) are routed into Containment and are evaluated for Safe Shutdown capability on an area by area basis.
Other cables that leave the Control Room are assumed to be low level instrument cables, buffered by their power supplies, independent of the NI needed for Safe Shutdown. Based on system and area analysis these circuits are acceptable from an Appendix R standpoint.

A review of the 4kV breaker settings has been performed for the Safe Shutdown electric plant configuration. See the electrical calculation for the individual feeder. The accredited Train cables have been shown to be free of fire damage and are, therefore, not a coordination concern.

Electrical coordination may be lost due to a fire-induced fault in this cable. No credit is taken for the availability of the MCC if there is inadequate separation or protection.
- 22.
A review of coordination of the loads on MCC F71 has shown that one non-Safe Shutdown Load, Y3401 (50-amps) may not coordinate with the incoming 600-amp molded-case circuit breaker. This MCC is needed only for fire in Area EE (Aux Bldg.
Fan Alley) and Y3401 serves loads in the Turbine Building, therefore, these are not associated circuits of concern.
- 23.
Cable 2CV&432E serves a single sample valve in the same fire area as the Power Supply RC4607 and either 3-amp fuse provides adequate circuit protection.
- 24.
YE2(YF2) molded-case circuit breakers do not coordinate with the incoming circuit breaker. The only Safe Shutdown loads off these MCCs are SFRCS. Loss of this power to the failsafe system is conservatively assumed. The coordination of YE1(YF1) partly relies on length of cables 1PYE104A and 2PYF104A attenuating the fault current.
- 25.
The delay band is adjusted to the maximum end the breakers are coordinated.
- 26.
Calculations have shown that Y1, Y1A, Y2, Y2A, Y3 and Y4 are coordinated with only the CVT source fed from E16A and F16A. The lack of coordination with the normal sources (YRF1, YRF2, YRF3 and 4), is not a Safe Shutdown concern since the automatic transfer to the accredited source will occur when the current transformer senses approximately 120% overcurrent in the feeder to the panels. The current limiting fuses on these panels are effective in reducing the peak let-through current to levels which do not trip breakers in the accredited path.
- 27.
Coordination for F7 is given in Calculation C-EE-005.01-21 and for the bustie to F7 in Calculation C-EE-004.01-034, ground fault may result in tripping of F71; however, the motor-driven feed pump is only accredited for Safe Shutdown in Area EE and the cable is not routed in Area EE.
- 28.
A number of components and modules in the NNI cabinets and a number of field mounted components external to the NNI cabinets require 120 V AC rather than
+/-24 V DC for their operation. All of the components and modules which require 120 V AC power for their operation receive their power from the AC fuse panels in both the NNI X and NNI Y cabinets. The largest load fuse size is a Bus GLD 5 per field walkdown which is adequately coordinated with the incoming A2Y15 distribution fuse within the NNI X and Y cabinets.
- 29.
This circuit serves a single circuit scheme and a failure in any cable is evaluated to result in the loss of only the one component (RC2A as shown in DCN-E52B/13-535).
Therefore, the coordination is acceptable.

Coordination for the disconnect device for the Turbine Generator Emergency Bearing Oil Pump (D118) is given in Calculation C-EE-002.01-011. The disconnect device is a magnetic breaker only Westinghouse type HKA breaker rated at 225/70A (225A frame 70A rated breaker). The thermal trip is not installed and the magnetic trip (350A to
Davis-Besse Unit 1 Fire Hazard Analysis Report NOTES FOR APPENDIX C-3 C3-22 FHAR Rev 28 9/2018 700A) is set at 455A in accordance with Relay Setting Manual sheet 1-30-201. With the breaker set at 455A the breaker is coordinated with the upstream 500-amp fuse.
- 31.
As discussed in Attachment 10 of Calculation C-EE-002.01-011 (Ref. 2.6.E), the loads associated with the power supplies have been evaluated to be lost due to the fire (e.g.
D1P and D1N are both in the same fire area as their power supply DC MCC 1 and thus no credit is taken for these for a fire in this fire area.
