SUMMARY

The plant is operating at approximately 15% power with a reactor startup in progress. Drywell inerting is in progress. The 1-0640-29B, B narrow range RPV level instrument is OOS reading downscale. The B EHC pump and HPCI are OOS. IRM #15 is bypassed.

The crew will assume the shift with orders to transfer auxiliary power (BOP-N) and continue the startup by pulling control rods (RO-R). During control rod withdrawal the RBM #7 enable setpoint will drift down causing a rod out block (RO-I). After the RBM is bypassed a control rod will come uncoupled at position 48 (RO-C, SRO-T). Actions to re-couple the control rod will fail and it will be fully inserted.

An operator will report from the field that he felt vibrations in the plant and the seismograph has actuated.

A steam leak will develop in RCIC and the group V isolation will not actuate requiring the operator to isolate it manually (BOP-C, SRO-T).

A recoverable loss of instrument air will occur. The operator will start standby instrument and service air compressors (BOP-C). The NLO will be able to isolate the leak.

A rupture of the circulating water piping and subsequent flooding of the condensate pit will require the crew to scram the reactor and secure the condensate and feed pumps (M-All).

After the scram a leak in the A recirc suction header will develop. The crew will be unable to control level above the top of active fuel requiring a blowdown (M-All). RPV level will be recovered using low-pressure ECCS pumps.

The scenario will be terminated when primary containment parameters are lowering and RPV level is in a band of 0 - 48.

CRITICAL TASKS:

Critical task #1: When level approaches -59 INHIBIT ADS to prevent uncontrolled RPV depressurization. (BWROG RPV-4.2/5.2/6.2) Important PSA task/ Inhibit ADS has Risk achievement Worth RAW) of 6.06. Accomplishing this task terminates 2 of the 20 most probable Core Damage Sequences.)

Critical task #2: With the inability to maintain RPV level above -142 inches with an injection source lined-up and running INITIATE an emergency depressurization before RPV water level drops to -166" (Minimum Steam Cooling RPV Water Level) (BWROG RPV-1.1 LOSS HP INJ E/D TAF)

Critical task #3: When Torus pressure exceeds 5 psig, INITIATE drywell sprays, while in the safe region of the drywell spray initiation limit (DSIL).

SUMMARY

The plant is operating at approximately 15% power with a reactor startup in progress. Drywell inerting is in progress. The 1-0640-29B, B narrow range RPV level instrument is OOS reading downscale. The B EHC pump and HPCI are OOS. IRM #15 is bypassed.

The crew will assume the shift with orders to transfer auxiliary power (BOP-N) and [that the startup is on hold].continue the startup by pulling control rods (RO-R). During control rod withdrawal the RBM #7 enable setpoint will drift down causing a rod out block (RO-I). After the RBM is bypassed a control rod will come uncoupled at position 48 (RO-C, SRO-T). Actions to re-couple the control rod will fail and it will be fully inserted. [ Events NOT used ]

An operator will report from the field that he felt vibrations in the plant and the seismograph has actuated.

A steam leak will develop in RCIC and the group V isolation will not actuate requiring the operator to isolate it manually (BOP-C, SRO-T).

A recoverable loss of instrument air will occur. The operator will start standby instrument and service air compressors (BOP-C). The NLO will be able to isolate the leak.

A rupture of the circulating water piping and subsequent flooding of the condensate pit will require the crew to scram the reactor and secure the condensate and feed pumps (M-All).

After the scram a leak in the A recirc suction header will develop. The crew will be unable to control level above the top of active fuel requiring a blowdown (M-All). RPV level will be recovered using low-pressure ECCS pumps.

The scenario will be terminated when primary containment parameters are lowering and RPV level is in a band of 0 - 48.

CRITICAL TASKS:

Critical task #1: When level approaches -59 INHIBIT ADS to prevent uncontrolled RPV depressurization. (BWROG RPV-4.2/5.2/6.2) Important PSA task/ Inhibit ADS has Risk achievement Worth RAW) of 6.06. Accomplishing this task terminates 2 of the 20 most probable Core Damage Sequences.)

Critical task #2: With the inability to maintain RPV level above -142 inches with an injection source lined-up and running INITIATE an emergency depressurization before RPV water level drops to -166" (Minimum Steam Cooling RPV Water Level) (BWROG RPV-1.1 LOSS HP INJ E/D TAF)

Critical task #3: When Torus pressure exceeds 5 psig, INITIATE drywell sprays, while in the safe region of the drywell spray initiation limit (DSIL).

SUMMARY

The plant is holding load at 90% power. The 1-0640-29B, B narrow range RPV level instrument is OOS reading downscale. The 1B TBCCW pump is OOS. APRM #1 is bypassed.

When the crew assumes the shift the A core spray pump will autostart but its minimum flow valve will fail to open. The operator will secure the pump (BOP-C, SRO-T). A control rod will drift out 2 notches and will be inserted using the QCOA (RO-C, SRO-T). The on line gland sealing steam exhauster will trip requiring the other to be placed in service (BOP-C). [ Event NOT used ]

A loss of Reserve Aux Transformer 12 will occur (SRO-T). A load drop to less than 2511 MWth will be performed (RO-R) and 1 RFP and 1 condensate pump will be secured (BOP-N).

The other narrow range RPV level instrument will fail upscale causing the operator to take manual control of feedwater (RO-I).

An inadvertent Group I isolation will cause a steam leak in the drywell (M-All). Drywell sprays will be unavailable and the drywell coolers will not restart. The crew will blowdown due to the inability to stay within the PSP curve or maintain DW temperature (M-All).

When saturation conditions are met all RPV level instruments will become unavailable and the crew will flood the RPV (M-All).

The scenario will be terminated when the crew identifies indications that the RPV is flooded to the main steam lines.

CRITICAL TASKS:

Critical task #1: When Torus cannot be maintained below the Pressure Suppression Pressure (PSP), INITIATE emergency depressurization.

Critical task #2: When RPV level cannot be determined, inject to establish flooding conditions.

SUMMARY

The plant is holding load at 90% power. The 1-0640-29B, B narrow range RPV level instrument is OOS reading downscale. The 1B TBCCW pump is OOS. APRM #1 is bypassed.

When the crew assumes the shift the A core spray pump will autostart but its minimum flow valve will fail to open. The operator will secure the pump (BOP-C, SRO-T). [ Event NOT used ]

A control rod will drift out 2 notches and will be inserted using the QCOA (RO-C, SRO-T).

The on line gland sealing steam exhauster will trip requiring the other to be placed in service (BOP-C). [ Event NOT used ]

A loss of Reserve Aux Transformer 12 will occur (SRO-T). A load drop to less than 2511 MWth will be performed (RO-R) and 1 RFP and 1 condensate pump will be secured (BOP-N).

The other narrow range RPV level instrument will fail upscale causing the operator to take manual control of feedwater (RO-I).

An inadvertent Group I isolation will cause a steam leak in the drywell (M-All). Drywell sprays will be unavailable and the drywell coolers will not restart. The crew will blowdown due to the inability to stay within the PSP curve or maintain DW temperature (M-All).

When saturation conditions are met all RPV level instruments will become unavailable and the crew will flood the RPV (M-All).

The scenario will be terminated when the crew identifies indications that the RPV is flooded to the main steam lines.

CRITICAL TASKS:

Critical task #1: When Torus cannot be maintained below the Pressure Suppression Pressure (PSP), INITIATE emergency depressurization.

Critical task #2: When RPV level cannot be determined, inject to establish flooding conditions.
