ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Examination Outline Cross-reference: Level RO SRO Tier # 2 Group # 1 KIA # 223001 2.1.28 Importance Rating 3.2 Primary Containment System: Knowledge of the purpose and function of major system components and controls.
Proposed Question: Common 7 What is the energy flowpath from the drywell air space to the torus should a high pressure line break occur in the drywell?
A. The drywell to torus vacuum breakers open to relieve the pressure from the drywell to the torus.
B. The drywell to torus vent pipes relieve the pressure from the drywell air space to the torus water volume via a ring header and downcomers.
C. Six-foot vent pipes relieve the pressure from the drywell air space to the torus air space.
$ 1 D. Eight vent pipes discharge to the torus water volume via tee-quenchers.
Proposed Answer: B Explanation (Optional):
A. Incorrect - The drywell to torus vacuum breakers open to prevent the DW pressure from being significantly reduced below Torus pressure following the energy blowdown from the DW to the Torus. During the blowdown these valves will be held closed by the high DP between the DW and the Torus. These valves must be closed during the blowdown phase to ensure the pressure suppression function of the containment is not bypassed.
B. Correct Response C. Incorrect - As described below the 8 vent pipes (which are slightly greater than 6 feet) are attached to the Torus Ring Header and downcomers. The energy transfer is from the DW air through this vent system to the torus water volume.
D. Incorrect - The eight vent pipes discharge to the Torus ring header. The high energy is then transmitted to the Torus Water Volume by 96 downcomer pipes attached to the Torus Ring Header. These downcomers are straight pipes which blow directly down into the torus water volume (not T-quenchers).

C. high drywell pressure (RHR drywell pressure logic)
D. loss of MCC power Proposed Answer: A Explanation (Optional):
A. Correct - Increased drywell pressure and moisture increase the work done by the RRU motors and cause the thermal overloads to trip at drywell pressures of 10-14 psig.
B. Incorrect - Low drywell pressure causes an isolation of the drywell sprays and torus but does not affect RRU operation.
C. Incorrect - The operator had already bypassed the RRU high drywell pressure RRU trip to restart them after the large leak caused drywell pressure to exceed 2.5 psig which trips the RRUs and is the entry condition for EOP-3.

Proposed Question: SRO 93 The plant is at 90% power when the following alarms are received 0 6-D-4 Atmos DRN Tk LVL Hi/Lo 0 6-D-5 Atmos DRN Tk LVL CTRL VLV OPEN Main condenser vacuum is slowly degrading.
Based on these plant parameter indications you determine that -(l)- and INITIALLY direct the operator to -(2)-.
A. (1) tank Level is Low
, (2) fail the level control valve closed in accordance with the instructions in ARS 6-D-4 to stop the degrading vacuum B. (1) tank Level is Low (2) immediately reduce power in accordance with OT 3120 Condenser High Back Pressure, to stop the degrading vacuum C. (1) tank Level is High (2) fail the level control valve closed in accordance with the instructions in ARS 6-D-4 to stop the degrading vacuum D. (1) tank Level is High (2) immediately reduce power in accordance with OT 3120 Condenser High Back Pressure High, to stop the degrading vacuum Proposed Answer: A Explanation (Optional): KA match for system is based on the atmospheric drain tank being considered part of the condensate system.
NUREG-1021, Revision 9
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet A. Correct - This event has happened at the plant and operators had difficulty diagnosing it.
When the level control valve sticks open, the tank level goes Low and allows air to be drawn into the main condenser. ARS 9-6-D-4 discusses how to fail the LCV shut and stop the loss of vacuum.
B. Incorrect - Reduction in power is not initially procedurally directed for this event.
C. Incorrect - When the tank overfills, vacuum is not affected - vacuum will not be affected.
D. incorrect - When the tank overfills, vacuum is not affected. Reduction in power is not initially procedurally directed.
