Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES
This normally closed valve should be closed when Train 1(2) of AFW is being utilized.
The concern is if this valve spuriously opens, thereby diverting AFW to the opposite SG.
However, the decay heat removal function is satisfied by feeding either or both steam generators.
The AFW pump capacity is such that even if this valve did spuriously open, and thereby divert flow to Train 2(1), adequate Auxiliary Feedwater supply would still be available to maintain the inventory in SG1-1(SG1-2) (Reference 2.3.H (6.8)). However, spurious opening of this valve is a concern from the point of view of inadvertently overfilling the opposite SG, thereby potentially overcooling the RCS and/or introducing water into the AFWS steam supply. Any spurious open signal can be blocked or the valve can be reclosed locally. LY6453(6454) SG Auto Essential Level Control Circuits 1544B/24 are included in the database for conservatism only. Auto control on high or low level achieves SSD; therefore, control power from RC3701 is not required.
- 2. Valves AF608 (AF599) are required to remain open to provide AFW to one SG1-1(SG1-2). In addition, flow to SG1-1(SG1-2) requires 1 of the following valves to to be open: AF3870 or FW6398(AF3872 or FW6460).
- 3. Valve ICS038B(ICS038A) is required to remain open to provide Main Steam to the AFW Pump Turbine 1(2), thereby assuring the operability of AFW Pump 1(2). AFW flow is controlled by modulating AFWP Flow Control Valve AF6452(AF6451). If level control is unavailable, speed control can be used to regulate AFW flow. The power supplies and control circuits for ICS038B(ICS038A) can be operated from either the MCR or ASP.
- 4. Valve AF6452(AF6451) is a DC modulating solenoid level control valve which fails open for SSD. AC is required to modulate to control the amount of AFW entering SG1-1(SG1-2) in automatic level control, but manual control is from either the Control Room or ASP is assumed for Safe Shutdown. (See also Note 3, speed control is a backup means of regulating AFW flow). Control Panel C3645 (C4625) provides AC control power.
- 5. The power supply to the scheme is not needed for Safe Shutdown. For example, E1, F1, and F7 MCC breakers fail [AS IS] upon loss of control power, (See E34B/16 and E34B/23A). Also, control power is not needed if control circuits fail in the SSD position.
Control power for indicating lights is included for conservatism, but is not essential for Safe Shutdown.
- 6. Normally closed Valve MS106(MS107) opens to provide steam to AFW Turbine Driven Pump 1-1(1-2) whenever SFRCS is initiated. Manual actions ensure a steam supply to both AFPTs after manual initiation or a false isolation condition as a result of shorts on complimentary steam pressure channels (See E18 sht 1).
Flow can also be established using the manual cross-connect valves MS728 and MS733 along with MS106A (MS107A).
- 7. Normally open Valve MS106A(MS107A) provides steam to AFW Pump Turbine 1-1(1-2) from SG1-2(SG1-1). IF MS106A(MS107A) remains open or spuriously reopens while A-25 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES feeding only SG1-1, SG1-2 could boil dry. MS106A (MS107A) can be manually closed if feed using only one AFPT is desired.
From Reference 2.3.H (6.8), it has been determined that the steam output from SG1-2(SG1-1) is such that the output capacity is sufficient to run the AFW Pump Turbine 2(1) even if the valve was open thereby diverting some steam to Train 1(2) (this is conservatively assuming the case where ICS038B and MS5889A(ICS038A and MS5889B) is open and cannot be closed). Boiling dry 1 SG will not prevent natural circulation in the other SG.
- 8. Valve MS5889A(MS5889B) is required to open to admit steam to AFW Pump Turbine 2 (1). SV5889A(SV5889B) fails open on SFRCS signal, or loss of power or air supply.
- 9. Turbine Driven Pump P14-1(P14-2) is required to be operable for operation of AFWS Train 1(2). See also Note 7, both AFPTs start on manual initiation or SFRCS (Trip 5RCMP monitor on Loss of Offsite Power. See E18).
- 10. Motor Driven Feedwater Pump P241 provides an alternate supply of AFW in the event the Turbine Driven Feedwater Pumps are unavailable.
- 11. Pump P242-1 is required to be available to support MDFP operation.
- 12. Pump P242-2 supports operation of the MDFP. This pump is strictly mechanical in nature.
- 13. NUMBER NOT USED
- 14. Valve FW6459(FW6460) is required to modulate to control the amount of AFW supplied to SG1-1(SG1-2) by the MDFP.
- 15. MDFP Seal Water Coolers E183, E184-1 and E184-2 are required to be functional to cool the MDFP Seals. These are strictly passive mechanical components.
- 16. Condensate Storage Tank T31-1(T31-2) is required to be functional to supply AFW to AFW Pump 1(2).
- 17. Only 1 CAC unit fan (i.e. C1-1 or C1-2) and its associated cooling coil (i.e. E37-1 or E37-2) is required operable, when shutting down, to maintain containment temperature within operational limits for the instruments in Containment (References 2.3.H (6.8 and 6.10)). Only 1 CAC unit is assured in the Appendix R evaluation in the event of a fire anywhere in the plant. C1-3 is not relied upon for shutdown.
- 18. Valves CC1467 (Train 1) and CC1469 (Train 2) are required to open for plant Shutdown in order to provide cooling for the Decay Heat Removal Coolers. Note that these valves are required to achieve Cold Shutdown (valves are solenoid operated).
- 19. Valves CC1471 (Train 1) and CC1474 (Train 2) are required open for plant Shutdown in the case of a Loss Of Offsite Power (LOOP) to provide cooling to the EDG Jackets.
These are normally open manual valves.
A-26 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES
- 20. Valve CC1495 provides CCW to a nonessential portion of the CCWS. This valve needs to be assured closed for Shutdown in order to preclude substantial flow diversion that should ordinarily go to the essential portion of the CCWS and the Containment Header.
- 21. Valve CC2645(CC2649) is required to be open to provide CCW return flow from the Seal Return Coolers and is required for Safe Shutdown.
- 22. Valve CC5095(CC5096) is normally open when Train 1(2) is being utilized during normal operation. It is required open for Safe Shutdown to provide cooling to MUPS Letdown and Seal Return Coolers. Manual actions are required in some fire areas.
- 23. CCW Heat Exchangers E22-1, E22-2 and E22-3 and CCW Surge Tank T-12 are required to be functional to support operation of the CCWS. These components are passive mechanical components.
- 24. Of the 3 centrifugal CCW pumps (i.e. P43-1, P43-2 and P43-3), 1 is normally operating, 1 is in standby and 1 is an installed spare. Each pump is rated at 7860 gpm (at 65 psi).
The minimum flow requirements of the CCW Pump is 1000 gpm. The Appendix R review considers that only 1 CCW loop is necessary to achieve Cold Shutdown.
The 2 component cooling loops are interconnected downstream from the heat exchangers to essentially form an open loop supply header for loads that are nonessential. One CCW pump is adequate to provide cooling water to the respective essential header and the nonessential containment header only. For this reason, valve CC1495 needs to be assured closed to avoid CCW flow diversion to the other nonessential headers.
- 25. Valve CC1460 is only required open for those instances where the Makeup System is accredited for Safe Shutdown. This valve supplies CCW to the Makeup Pump Gear and Pump Lube Oil Coolers. Manual action may be required if air and power are unavailable. Manual valves are installed from the essential CCWS headers to the respective pump coolers and effectively bypass CC1460.
- 26. CCW Inlet Isolation Valves CC1411A and B and Outlet Isolation Valves CC1407A and B are required to remain open to provide cooling to the RCP Seals and Makeup Letdown Coolers.
- 27. Valves CC5097 (Train 1) and CC5098 (Train 2) provide Return Flow from the Makeup Letdown Coolers. Manual actions are required in some fire areas.
- 28. Valves CC1409 and CC1410 provide Inlet CCW Flow to the RCS Letdown Coolers (E25-1, 2). These valves are required to remain operable when letting down from the RCS.
- 29. NUMBER NOT USED
- 30. Normally energized Flow Switch Relays FIS1422D, FIS1427C, FIS1427D, and FIS1432C monitor flow from the CCW pump and on sustained low flow or loss of control A-27 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES power starts the backup pump. On low flow, these switches also provide a signal to open the respective standby CCWS Header (Valves CC2645, CC5095, CC5097, CC2649, CC5096, CC5098).
- 31. Valves CF01A and B are required to be closed when going to Cold Shutdown at an RCS Pressure of approximately 600 psig, to preclude dumping water from the Core Flood Tank into the RCS. The Core Flooding System is only required to operate in the event of a Loss Of Coolant Accident (LOCA).
- 32. Fans C21-1 (Train 1) and C21-2 (Train 2) supply cool air from the emergency condensing units to the Control Room. The fans are required operable to maintain proper temperature for Control Room instrumentation and habitability.
- 33. A/C Units S33-1 (Train 1) and S33-2 (Train 2) (water-cooled) cool the incoming air to provide suitable temperatures for the Control Room.
- 34. A/C Units S33-1(S33-2) Refrigerant Isolation Valve SV4823A (SV4827A) provide refrigerant to the Service Water cooled condensing heat exchanger and are required for proper operation of S33-1(S33-2).
- 35. NUMBER NOT USED
- 36. NUMBER NOT USED
- 37. The CREVS Cooling Coils E106-1 and E106-2 are required functional to assure proper operation of CREVS. These are passive mechanical components and will not be affected by a fire (except in Fire Area HH, where the components are located).
- 38. The CREVS Filter Banks F22-1 and F22-2 filter the air entering the Control Room.
These are passive components and will not be affected by a fire outside of the Control Room (except in Fire Area HH, where the components are located).
- 39. Pumps P56-1 (P56-2) is required not to spuriously start in the case that the associated CTMT Spray Valve CS1530 (CS1531) spuriously opens. Procedures call for tripping the pump.
- 40. Valves CS1530 and CS1531 are required not to spuriously open only if the associated CTMT Spray Pump also spuriously starts. The spurious opening of 1 of these valves concurrent with the spurious starting of the associated pump would spray unwanted water into CTMT, thereby potentially causing primary system depressurization.
- 41. Pumps P42-1 (Train 1) and P42-2 (Train 2) provide flow for the DHR/LPI mode. The pumps are required to be operable to achieve cold shutdown.
- 42. Valves DH01A (Train 2) and DH01B (Train 1) are normally open and are required to remain open to allow injection into the RCS during decay heat removal.
- 43. Valves DH07A (Train 2) and DH07B (Train 1) provide BWST inventory to the DHR/LPI pumps in the LPI mode, and the HPI System for high pressure RCS Injection. Since A-28 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES Valves DH7A and DH7B are normally depowered, spurious actuation of these valves is not a concern.
- 44. Valves DH09A (Train 2) and DH09B (Train 1) provide suction from the Containment Sump in the event of a LOCA when BWST inventory is de-pleted. The valves are normally closed and are required closed for Safe Shutdown, from an Appendix R standpoint, so that BWST inventory is not diverted to the CTMT sump in the event of spurious opening of the valves. If this were to occur, the Containment Emergency Sump could fill up with water to the point that water could come in contact with the Reactor Vessel and thereby possible cause thermal shock. Since Valves DH9A and DH9B are normally depowered, spurious actuation of these is not a concern.
- 45. Valves DH11 and DH12 are required to be open when the system is operated in the DHR mode. Alternatively, Manual Valves DH21 and DH23 may be opened locally to bypass these valves. (Since valves DH11 and DH12 are normally depowered, spurious actuation of these valves is not a concern).
- 46. Valves DH1517 (Train 1) and DH1518 (Train 2) are required to be open in the DHR mode to provide suction for the DHR Pumps from the Reactor Coolant System.
- 47. Valves DH2733 (Train 1) and DH2734 (Train 2) are required to be open to provide BWST inventory to the RCS in the LPI mode.
- 48. Valves DH13A (Train 2) and DH13B (Train 1) provide the capability to bypass the DHR Coolers. They are normally closed. The inability to open these valves is not a concern.
Spurious actuation of the valves is the only concern.
- 49. Valves DH14A (Train 2) and DH14B (Train 1) are normally open and are required to be open to provide flow through the DHR Coolers when in the DHR mode.
- 50. NUMBER NOT USED
- 51. Valves DH63 (Train 2) and DH64 (Train 1) are required to be open when in the Piggyback mode of the HPI System. They are required to be closed when in the DHR or LPI mode. Note that the Piggyback mode of HPIS, is not accredited for Safe Shutdown.
- 52. Valves DH2735 and DH2736 are located in the Decay Heat Removal System Pressurizer auxiliary spray flowline. Spurious simultaneous opening of both valves when Reactor Coolant system pressure is less than the operating pressure of the High Pressure Injection /Decay Heat Remoal System could result in loss of Reactor Coolant System pressure control. Spurious opening of these valves is not a concern when Reactor Coolant System pressure is greater than the operating pressure of the High Pressure Injection/Decay Heat Removal System because Check Valve RC51 would prevent backflow.
- 53. NUMBER NOT USED A-29 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES
- 54. DHR Coolers E27-1 and E27-2 are required functional to support proper operation of the DHRS. These components are passive mechanical components.
- 55. The BWST (T-10) is required functional to provide a source of borated water for the DHR/LPI, HPI and Makeup Systems.
- 56. Pumps P195-1 (Train 1) and P195-2 (Train 2) are only required to fill the EDG Day Tanks on low Day Tank level. However, each Day Tank has a 20-hour capacity of fuel oil to supply the EDG. Therefore, these pumps would only be required after 20-hours of EDG operation.
- 57. Valves DA2987, DA2988, DA2989 and DA2994, as well as valves DA60, DA61, DA62, and DA63, are air-actuated valves controlled by air from valves DA1147A/B (Train 1) and DA1148A/B (Train 2).
Since these valves have no electrical interface, they are included on the SSCL (Appendix A) but are not identified in Appendix B.
- 58. Either the engine-driven Fuel Oil Pumps [P205-1 (Train 1) and P205-2 (Train 2)] or the motor-driven Fuel Oil Pumps [P201-1 (Train 1) and P201-2 (Train 2)] can supply fuel oil to the engine. The DC motor-driven fuel oil pumps are a backup to the engine-driven pumps. The engine-driven pumps are integral to the EDG.
- 59. Valve DA1147A, B (Train 1) and DA1148A, B (Train 2) are required to open to introduce air from the EDG Starting Air Receivers to the Air Starting Motors.
- 60. EDGs K5-1 and K5-2 are required operable to power the essential electrical distribution system in the event of a Loss Of Offsite Power (LOOP).
- 61. EDG Day Tanks T46-1 and T46-2 supply fuel to the EDGs. They are required to remain functional. No remote indication is available to monitor EDG Day Tank level. However, the day tanks are sized to provide fuel for at least 20-hours. Level indication is provided locally.
- 62. The fuel oil in EDG Fuel Oil Storage Tanks T153-1 and T153-2 is required only after the Day Tank level is depleted. However, a backup supply of fuel maybe provided via an Emergency Fill Connection.
- 63. Each receiver (i.e. T86-1 through -4) has the capacity to provide 5 starts without recharging. They are strictly passive mechanical components. They are required to remain unaffected by a fire.
- 64. The air starting motors are used to start the EDGs and are strictly mechanical devices.
There are 8 of these motors, 1 set of 2 per air receiver.

119. NUMBER NOT USED 120. The Main Steam Isolation Valve MS101 (MS100) is required to shut to isolate SG1-1(SG1-2) and thereby provide steam to the AFW Pump Turbine 1(2). SV101C, F (SV100C, F) are not required for Safe Shutdown, MS101(100) will close on spring pressure.
121. Valve MS101-1(MS100-1) bypass MS101(MS100) and is opened during Startup to heat the downstream of the Main Steam System before MS101(MS100) is opened. During normal operation the valve is closed. The concern is that if the valve was to spuriously open that steam would be diverted to the condenser instead of the AFW Pump Turbine.
The valve is located on a 2-inch line which could potentially divert significant steam if the valve was too inadvertently open. Since this is a spurious open concern only, control power is not required for SSD.
122. NUMBER NOT USED 123. NUMBER NOT USED 124. Valve ICS11B(ICS11A) provides secondary side pressure control and RCS cooldown capability when the condenser is not available. This valve is required operable to achieve Hot Standby and for going to Cold Shutdown, but fails closed on loss of air or the SV-ICS11A(B) and local manual operation is required by Procedure DB-OP-02501, Serious Station Fire.

132. The Makeup Pump Discharge Valves MU6419 (Train 1) and MU32 (Train 2) are required to be open to allow for Makeup Pump discharge to the RCS. Alternatively, MU32 Bypass Valve MU6420 may be opened in lieu of MU32 in the event MU32 cannot be opened.
133. The Makeup Cross Connect Isolation Valves MU6409 (Train 1) and MU6408 (Train 2) are required to remain open to provide Makeup flow for RCP Seal injection and Makeup Recirculation Flow to the BWST.
134. The Makeup Recirculation Isolation Valves MU6407 (Train 1) and MU6406 (Train 2) are required to remain open to provide a Makeup flow recirculation path to the Makeup Tank until RCS Injection is established. These valves need to close once RCS Injection is commenced. Makeup recirculation to the BWST is established by opening manual Valves MU208, HP29 and HP1556 locally.
135. The 3-way Makeup Pump Suction Valves MU6405 (Train 1) and MU3971 (Train 2) are required to be operable to realign Makeup System suction from the Makeup Tank to the BWST.
136. The Makeup Tank (T-4) provides an initial source of borated water for RCS Injection utilizing the Makeup System. In the event inventory in the Makeup Tank is depleted, the BWST provides a backup supply of borated water for RCS Injection. Note that no remote Makeup Tank monitoring capability exists.
137. The Seal Injection Inlet Isolation Valve MU19 is required to be throttled to provide proper amount of Makeup System flow to the RCP Seals. In the event this valve is unavailable, Manual Isolation Valve MU214 can be closed and Manual Bypass Valve MU216 can be throttled.

142. The RCS Seal Return Coolers E26-1 and E26-2 are required to ensure proper cooling of the RCS Seal Return. These are passive mechanical components and will not be affected by a fire.
143. When RCS Letdown is required to be isolated in order to maintain RCS inventory, either MU02A or B can be closed to isolate Letdown. Alternatively, both MU01A and B or MU03 can be closed to perform this function. RCS Inventory control is maintained by a controlled plant cooldown if letdown is not available. Although RCP seal injection and letdown are not required for safe shutdown, they are detailed in the FHAR because availability of these systems simplifies safe shutdown and results in enhanced plant control. In such a case, Valves MU02A, B, MU03 and either MU01A or B must be assured open. Valve MU03 requires local manual operation if air or solenoid power is unavailable.
144. The Makeup System Letdown Coolers E25-1 and E25-2 are required to ensure proper RCS Letdown cooling.
145. The Letdown Block Orifice Isolation Valve MU04 is required to be open to promote RCS Letdown. Alternatively, manual bypass valve MU06 may be opened to provide RCS Letdown. Note that this valve may be closed for RCS Letdown isolation in lieu of Valves MU02A, B, MU03 or MU01A and B. Note that Valve MU04 is not powered by the diesels and would therefore not be remotely operable in the event of a Loss Of Offsite Power (LOOP).

Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES LI-SP09B3 in the ASP are required. I.E. Information Notice 84-09 requires the availability of wide range SG Level Indication for S/D. However, the preferred mode of operation by TE is to use the Startup Range Monitors (0-250) which are provided from both the Control Room and Auxiliary Shutdown Panel because they are safety grade, and in the cooldown mode the AFW System will be operating such that steam gene-rator(s) level is to be maintained within this monitoring range. Should the steam generator level rise above the specified range, AFW will be automatically or manually stopped (from the Control Room or Auxiliary Shutdown Panel) to bring down SG level.
The full (wide) range (0-600) SG Level Indicators are not used during power operation and are primarily used when filling and draining the SGs.
158. LI-SP09A8 and LI-SP09A9 (LI-SP09B8 and LI-SP09B9) provide a redundant means of monitoring SG1-2 (SG1-1) Startup Level in Fire Area FF at the SFRCS Cabinets located in the Cabinet Room (Room 502).

162. HPIS Flow Indicators FYI-HP03A, -3B, -3C and -3D in the Control Room and FYI-HP03A1, -B1, -C1 and -D1 in the ASP are required. I.E. Information Notice 84-09 requires that diagnostic instrumentation be available for Shutdown. HPIS Flow Indication is to be assured available to aid Operations personnel in direct indication of HPIS Injection into the RCS. The power supplies for HPI flow transmitters are the essential metering cabinets X & Y (C3628 and C3629). Both are located in Fire Area R, Room 322. Pressurizer Level Indicator LT-RC-14-2 is powered by NNI and is independent of Fire Area R. This provides an indirect measurement of HPI flow during Shutdown after a fire in Room 314 or 322 which could disable all HPI flow transmitters.
Manual actions also provide for reading HPI Pump Suction and Discharge Pressure to determine flow. For details of the essential metering cabinet refer to Drawing M-544-14-9. For details of the Auxiliary Shutdown Panel refer to Drawings M-544-5-15, M-544-6-10 and M-592 Rev. 6. NNI-X (C5759 B-F) and NNI-Y (C5760 D-F) power supplies are fed from an internal ABT.

164. Direct diagnostic indication of Makeup Pump 1 runout is provided in the Control Room by Makeup Flow Indicators, FI-6425 and FI-6435 and locally at the pump via discharge pressure indicator MU25A. Maintaining a minimum pressure of 2260 psig assures a pump flow of less than 250 gpm and no pump runout condition (Ref. 2.6.O).

The PORV must be assured not to spuriously open and thereby inadvertently blowdown RCS inventory. The PORV is accredited for providing RCS Depressurization to the HPI Pump Discharge pressure for the case where the HPI System is accredited for RCS inventory control. Alternatively, RCS Depressurization may be performed by opening valves RC200 and RC239A.
172. The spurious opening of RC200 in conjunction with the opening of RC239A, RC239B or RC4632 would result in Pressurizer blowdown to the Pressurizer Quench Tank.
Therefore, either RC200 or both RC239A and B and RC4632 must be assured closed for Shutdown. In those fire areas where credit is taken for RCS Depressurization via the Pressurizer Vent Header, Valves RC239A and RC200 must be assured operable.
173. NUMBER NOT USED 174. Valve RC11 provides an alternate means of isolating RCS blowdown in the event of spurious opening of the PORV. Valve RC11 is required to remain open if credit is taken for operation of the PORV for a fire in a particular fire area.
175. Each RCS Loop High Point Vent, 1 of the 2 Valves (RC4608A or B and RC4610A or B) is required to stay closed to prevent uncontrolled RCS blowdown via the High Point Vent. The one inch SG high point vent valve lines include a restricting orifice sized to limit the flow to within the Makeup System capacity.

Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES 178. NUMBER NOT USED 179. Normally, 2 of the 3 SW Pumps (P3-1, P3-2 and P3-3) are in operation with the third as a spare. One operating pump supplies primary (essential loads) and the other pump supplies nonessential loads and a few essential loads for the redundant train. To provide Service Water to the essential SW loads for Shutdown, only 1 SW pump is required.
180. In the unlikely event that all SW pumps are lost, the Backup SW Pump (P180) can be manually aligned and run on fast speed to supply primary loads.
181. NUMBER NOT USED 182. Valves SW2927 (Train 1) and SW2928 (Train 2) are required to open to supply the CTRM EVS condensing units with cooling water.
183. Valves SW1424 (Train 1), SW1434 (Train 2) and SW1429 (Train 1/2) associated with the respective CCWS train being utilized for Safe Shutdown will need to be assured open. The valve fails open to the desired Safe Shutdown operation, therefore power supplies are not required.
184. Valves SW1356 and SW1366 (Train 1), SW1357 and SW1367 (Train 2) or SW325, SW1358 and SW1368 (Train 1/2) are required to be open when shutting down with their respective Train in order to provide cooling water to the associated CTMT air cooler.
Only 1 Containment Air Cooler is to be in service during Shutdown to ensure adequate cooling is provided to other Safe Shutdown components cooled by the Service Water System. Spurious flow through CAC 3 will be prevented by normally closed manual Valve SW325 (SW331).
185. NUMBER NOT USED.
186. Valve SW1382 (Train 1) or SW1383 (Train 2) is required to be open when the CST Level reaches low level to provide an alternate supply of water for the Auxiliary Feedwater Pumps. In the event one of these valves can not be opened (e.g., hot short damages valve operator) an alternate source of makeup water from the Fire Water System is available.
187. One of 4 Valves (SW2929, SW2930, SW2931 or SW2932) is open and depowered at all times (controlled administratively) to ensure the availability of a SWS Discharge at all times. Thus, spurious closure of the applicable valve is not a problem. The other 3 valves will remain closed.
188. Valves SW1395 (Train 2) and SW1399 (Train 1) provide Service Water to the Turbine Plant Cooling Water System. The portions of the Service Water System supplied by these valves is not required for Safe Shutdown. Therefore, the only concern is that the valve(s) could remain open and provide substantial SWS Flow Diversion. The respective valve for the Train accredited for Shutdown in a particular fire area needs to A-40 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES be secured closed for Shutdown in order to assure adequate flow to the essential portion of SWS.
The capability of the SWS to supply Appendix R loads has been evaluated (See Ref. 2.6.Q).
189. SW45, SW46, SW54, SW55, and SWS6 are the Turbine Plant Cooling Water Heat Exchangers (TBCWHX) Isolation Valves. They serve as a backup means of isolating the TBCWHXs if SW1395 (Train 2)/SW1399 (Train 1) is unavailable.

The Main Steam Safety Valves are mechanical components with no circuits associated with them and a fire is not expected to impact their operation. The Train 1 and 2 Main Steam Safety Valves are located in Fire Area DH, but they are separated by more than 200 feet. There is no automatic suppression system in the fire area but there is area detection. The mechanical nature of the valves, the large separation distance between trains and detection in the area is an arrangement that is satisfactory in spite of the absence of the automatic suppression.
198. On a complete Loss of Offsite Power (LOOP), SFRCS will automatically initiate once all 4 RCPs sense UV, UF (E52B/49). All SFRCS transmitters and pressure switch circuits are designed to be self-monitoring of continuity and a fire-induced open or ground in any input channel will produce a logic channel trip for that individual monitored SFRCS input.
On a loss of control power or with sufficient trips on the inputs (see SF-003 logic diagrams) both AFPT are automatically started. Automatic SG isolation can be manually blocked (reset).
The Appendix R compliance with respect to potential effects of inadvertent actuation of the Safety Features Actuation System (SFAS) and the Steam and Feedwater Rupture Control System (SFRCS) is contained in Reference 2.3.D). This evaluation analyzed the potential for inadvertent actuation of the SFAS and SFRCS trips due to a fire and the resulting impact on Safe Shutdown equipment. The evaluations provided to ensure mitigation of the potential effects of these SFAS and SFRCS trips as analyzed in Reference 2.3.D are included in Section 4.6 in the Table 1s for each Fire Area.
A-41 FHAR Rev 28 9/2018
Davis-Besse Unit 1 Fire Hazard Analysis Report APPENDIX A NOTES Manual actions are required and are listed in the notes for individual Safe Shutdown components that are required to be in a position/mode other than that after an SFAS/SFRCS actuation. Cables for sensors and actuated devices are included for conservatism so that the potential effects of a fire are identified on a component level specifically for each fire area. Fire damage to the isolated analog low level instrument loop, 4 to 20 ma SFAS input signals cannot cause an SFAS, loss of Ch 1/3 or Ch 2/4 power supplies will initiate SFAS.
The SFRCS system has a first-out feed-only-good logic design that could align feedwater to only one of two intact steam generators if a false actuation signal were generated by a fire that opened 2 complimentary SG pressure channels. Since only one steam generator is required and since manual actions are proceduralized there is no adverse impact on safe shutdown.
Operation of the disconnect switches does not isolate all Control Room circuits and local manual actions are required to close/verify closed the following valves for a fire that affects any control cables since both sets of fuses could blow with a ground that is not cleared before the disconnect switch is operated:

209. CC43 is a manual bypass valve for CC1495. It can be used to regulate nonessential CCW if CC1495 fails closed due to loss of air or a loss of power to its solenoid valve.
210. When using the Motor-Driven Feed Pump to supply feedwater to Steam Generator 2, the Train 1 MDFP Flow Isolation Valve, FW6397, can be used to prevent the flow from diverting to Steam Generator 1 if the Train 1 MDFP Flow Control Valve is unavailable (i.e, due to a loss of Train 2 power).
211. The Makeup System is normally exposed to RCS pressure up to Restricting Orifice ROMU5. Per P&ID M-031A, Rev 43 and Plant Design Standard 12501-M-601, Revision 8, pg 7 the piping upstream of the restricting orifice (CCB) is 1500# class piping. The piping downstream of the restricting orifice is 150# class piping. The letdown relief valve MU1890 protects the low pressure letdown line and equipment from overpressure. If the letdown flow is stopped by erroneous closure of a valve in the low pressure portion of the letdown line, the letdown line pressure would immediately increase to the RCS operating pressure except for relief from the relief valve. Per SD-048, the relief valve capacity is sized to exceed the maximum letdown flow rate obtainable with the block orifice on line and flow control valve MU6 full open.
212. MU32 will fail open upon loss of air to the valve. MU32 will fail closed upon loss of NNI-X AC power supply, regardless of the NNI-X DC control signal to FYMU32.
