A. To lift the #1 seal into its starting position.

B. To lubricate the lower motor radial bearing.

C. To raise the anti-reverse rotation assembly to disengage the pawls.

D. To reduce motor starting torque and minimize thrust bearing friction wear.

Proposed Answer: D Explanation (Optional):

A. Incorrect. Done by RCS pressure.

B. Incorrect. Lift pump does not lubricate the lower bearing.

C. Incorrect. This occurs as the pump comes up to speed.

D. Correct. From RCS lesson To reduce starting torque and protect the babbit surfaces on bearings, an RCP oil lift system is used to supply oil to the thrust bearing shoes and upper radial bearing before the RCP motor is started. The pressure of the oil "lifts" the thrust shoes away from the thrust runner and supplies an oil film.

Proposed Answer: A Explanation (Optional):

NUREG-1021, Revision 9 5

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet South Texas, Unit 1 On 8-6-90 a boron dilution event occurred as a result of placing a chemical and volume control system mixed bed demineralizer into service, which had not been sampled for effluent boron concentration. The bed had not been in service for several months.

The dilution caused thermal power to increase gradually from 100% to 101% while the highest Nuclear Instrumentation power range channel reached 103.5%. Operators responded to the gradual power and coolant temperature rise by several increasingly larger rod insertions and boron additions.

Root Cause More detailed investigation revealed that the boration of this mixed bed was done in parallel with another bed in service and as such the boration was not totally accomplished.

It was also recognized that when a bed has been laid up for a lengthy period of time, boron absorption into internal vessel surfaces and resin bead surfaces could also cause reduction in boron concentration of the bed effluent.

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Examination Outline Cross-reference: Level RO SRO Tier # 3 Group # 3 K/A # G2.3.10 Importance Rating 3.3 Ability to perform procedures to reduce excessive levels of radiation and guard against personnel exposure.

Proposed Question: SRO 98 A job must be performed under the following conditions:

• Dose rate at job location is 90 mrem/hr.

• Airborne Radioactivity Area from particulates due to weld grinding:

o Internal dose if respirator is worn is 0 mrem.

o Internal dose if no respirator is worn is 82 mrem.

• Time to complete job while wearing a respirator is 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.

• Time to complete job without wearing a respirator is 2.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br />.

Which ONE (1) of the following describes whether a respirator will be worn, and why?

A. No, wearing a respirator will raise total exposure.

B. Yes, wearing a respirator will lower total exposure.

C. No, wearing a respirator will make no difference to the total exposure.

D. Yes, a respirator must be worn anytime airborne radiation is present.

Proposed Answer: B Explanation (Optional):

Without respirator: Total dose = 90 mrem/hr x 2.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> + 82 mrem = 329.5 mrem.

With respirator: Total dose = 90 mrem/hr x 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> = 315 mrem.
