SUMMARY

  • Initial Conditions:

o Unit 1 is operating at 100% power.

  • Event 1: The BOP performs a partial Acoustic monitor test, QCOS 0203-01 for SRVs 3A, 3B, and 3C.
  • Event 2: The breaker to a Drywell Spray Valve is found Deenergized due to an electrical fault. The SRO must address:

o TRM 3.6.a Condition A o T.S. 3.6.1.3 Power operated PCIV o T.S. 3.3.3.1 PAM Instrument

  • Event 3: The A CRD Pump trips. The ATC Operator and US respond per QCOA 0300-01 to start the B CRD Pump and open its discharge valve.
  • Event 4: Control Rod J-7 drifts out from position 00. The ATC and SRO respond per QCANs and QCOA 300-11. The rod should be inserted and scrammed. The SRO will declare control rod J-7 inoperable per TS 3.1.3, Condition C, requiring the inoperable rod to be fully inserted within 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and disarmed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
  • Event 5: The running Gland Seal Exhauster will trip. The BOP will start the standby Exhauster and adjust Gland Exhaust pressure.
  • Event 6: An air leak will result in lowering Main Condenser Vacuum. The crew performs QOA 3300-02 and Emergency Power Reduction. Prompt action by Equipment Operators to re-fill a loop seal line will stabilize Main Condenser Vacuum.
  • Event 7: Drywell Pressure starts to rise when a LOCA is initiated. A manual scram should be attempted per QCOA 0201-01 before Drywell Pressure exceeds 2.5 psig.

After Drywell Pressure exceeds 2.5 psig, QGA 100 and 200 are performed. The crew restores RPV Water Level and attempts to control Drywell Pressure and Temperature with Containment Sprays.

  • Event 8: Div II DW sprays are not available from event 2 (RHR 23B bkr trip) and Div I DW sprays are not available (S17 switch problem), requiring the crew to Blowdown in order to avoid exceeding Pressure Suppression Pressure (PSP).
  • Event 9: During the blowdown, a relief valve tailpipe will rupture and torus to DW vacuum breakers will fail open directly pressurizing containment. The crew will be required to vent containment to avoid exceeding PCPL.

CRITICAL TASKS:

Critical Task #1 When Drywell temperature CANNOT be maintained < 280 F OR Torus pressure CANNOT be maintained < the Pressure Suppression Pressure Limit, (PSP),

INITIATE an Emergency Depressurization..

Critical task #2: Before Torus pressure reaches the Primary Containment Pressure Limit (PCPL),

INITIATE venting of the containment irrespective of offsite radioactivity release rates. (BWROG PC-7.2 LOCA VENT PC VENT)

SR-1000-P02 Given a reactor plant in an accident condition (QGA), operate torus sprays in accordance with QCOP 1000-30 and appropriate QGA. (Important PRA Operator Action - starting containment sprays has a RAW value of 82.5)

SR-0001-P23 Given a reactor plant with rising containment pressure and temperature due to a LOCA or steam leak, initiate an emergency depressurization when torus pressure cannot be maintained below the Pressure Suppression Pressure (QGA Figure L) or when drywell temperature cannot be restored and held below 280 degrees in accordance with QGA 200 and QGA 500-1.

SR-0001-P24 Given a reactor plant with rising containment pressure due to a LOCA or steam leak, vent the containment irrespective of off-site radioactivity release rates before torus pressure reaches the Primary Containment Pressure Limit (QGA Figure D) in accordance with QGA 200 and QCOP 1600-13.

(Important PRA task. Failure to control containment venting or restore IA for venting results in core damage in 20 of top 100 Core Damage Sequences)

SR-0001-P25 Given a reactor plant with the inability to stay below the Primary Containment Pressure Limit (QGA Figure D), prevent injection from sources outside the primary containment not needed for core cooling or to shut down the reactor in accordance with QGA 100, QGA 101, QGA 200, or QGA 500-4.
