  8. Mandated Licensing Bases: UFSAR
    principal document used by the NRC to support issuance of an operating license
  9. Mandated Licensing Bases: TRM
    holds requirements that were relocated from the "old" tech specs
  10. Mandated Licensing Bases: Tech Spec Bases
    explains the reason for the requirement, but it not part of the operating license
  11. Protective Actions: SPTA's
    performed by control room staff to check safety functions upon entry into the EOPs
  12. Protective Actions: Safety Function Status Check (SFSC)
    section of each ORP that gives the CRS a second check of safety function status and a confirmation that the correct procedure is in use.
  13. Protective Actions: Functional Recvery Procedure (FRP) and Lower Mode Funcional Recovery (LMFR)
    provide and assessment of degraded safety functions and directions to their restoration.
  14. Eight Critical Safety Functions
    • 1. Reactivity Control
    • 2. Maintenance of Vital Auxiliaries
    • 3. RCS Inventory
    • 4. RCS Pressure
    • 5. Core Heat Removal
    • 6. RCS Heat Removal
    • 7. Containment Isolation
    • 8. Containment Pressure, Temperature, and Combustible Gases
  15. EOPs: Optimal Recovery Procedure (ORP)
    written to treat specific symptoms
  16. EOPs: FRP
    provides guidance undiagnosed and multiple events
  17. Normal Operating Temperature/Pressure
    • 2250 psia
    • Th=615
  18. Major Turbine-Generator Trip Sequences
    • 1. Simultaneous Trip: generator fault causes trip
    • 2. Sequential Trip: normal progression for all turbine/reactor trips
    • 3. Coast Down Trip: Loss of offsite power event
  19. Major Steps: SD Cooling Mode 5
    • Loops operable per T.S.
    • Temperature Control
    • SDC minimum flow
    • LTOPs relief valves
    • Shutdown purification
    • Secondary Plant Startup: 
    • Concurrent Secondary Plant Startup (Appendix E 40OP-9ZZ01)
    • Align long path recirculation
    • Prepare turbine generator auxiliaries
    • Draw a vacuum in condenser
    • Begin LP feedwater heating with AS
  20. Major Steps: Heatup (Mode 5 to Mode 4)
    • Draw a bubble in the pressurizer
    • Establish normal letdown
    • Start two RCP’s in the same loop
    • Control Heatup by bypass of SDCHX
    • Take SGs out of wet lay-up at 200°
    • Secure refueling purge
    • Restore SI
  21. Major Steps: Hot Shutdown (Mode 4)
    • Use SG for heat removal (AFW and SBCS)
    • When Tcold > 200°, start third RCP
    • When Tcold > 230°, secure SDC and
    • restore to injection line-up
    • When Tcold > 291°, isolate LTOPs
    • Pulsation Dampeners
    • Cycle Aux spray
  22. Major Steps: Hot Standby (Mode 3)
    • Prior to 350°, place CEDM ACUs in service
    • When pressure > 700 psia, pressurize SITs to 600 psia
    • Adjust CHG pump pulsation dampeners
    • When Tcold > 500°, start fourth RCP
    • When press 2250 psia, place PPCS in auto
    • Place SG blowdown is service
    • Dilute to within 50 ppm of ECBC
  23. Major Steps: Reactor Startup (Entry into Mode 2)
    • Verify adequate shutdown margin
    • Check nuclear instrumentation and CPC/COLSS
    • Withdraw the shutdown rods and PLCEAs
    • Dilute to ECBC
    • Initiate 1/M plots
    • Withdraw regulating groups to criticality
    • Increase power to POAH by withdrawing CEAs at 1 DPM SUR
    • Adjust cooling tower fan
    • Contingencies
  24. Major Steps: Mode 2 Operations
    • Use CEAs to increase to 2% power
    • Start turbine shell warming
    • Secure long path recirc and LP FW HTRs
    • Lineup extraction and heaters drains
    • Start second CD pump
    • Start MFW pump
    • Manual control of Downcomer valves to maintain SG level
    • Stop AFN pump
    • Use CEAs to increase to 5% power
  25. Dropped or slipped CEA: Event Description
    • Rod Falls, generates penatly factor
    • IF CEA is a shutdown group: Reactor Trip
    • OTHERWISE: CPCs generates penalty factor. Temp low, pressure lower, level lower
  26. Dropped or slipped CEA: Operator Actions
    • 1 - place CEDMCS in standby
    • 2 - Reduce turbine load so RCS will be on program
  27. Excessive RCS Leakage
    Pressure decrease, Pressurizer level decrease
  28. Electrical Load Rejection
  29. Loss of Main Feed Pump
  30. Loss of Condenser Vacuum
  31. Condenser Tube Rupture
