Clarifications During The Administration of the Kewaunee 2011 Initial License Written Exam on 2/15/2011, (Pen and Ink Changes)

Question 51:

Added a clarification to the second condition in the question stem to state that the turbine is latched.

The clarification was added based on a question from a student.

Original Question

51. Given the following:

- The unit is at 8% NI power, performing a startup after a refueling outage.

Preparations to begin rolling the Main Turbine are in progress.

- The Balance Of Plant operator identifies that P-486, Turbine Impulse Pressure Instrument, is reading off scale high.

- Shortly after the failure of P-486, RXCP A Trips.

- Annunciator 47012-J, RCS Loop A Flow Low, is LIT.

What is the expected Plant AND Operator Response?

Plant Response Operator Response A. Permissive P-7 will not The operators will manually trip the reactor cause a reactor to trip B. Permissive P-8 will cause The operators will perform the a reactor trip immediate actions for a reactor trip C. Permissive P-10 will not The operators will perform a normal cause a reactor trip reactor shutdown D. Permissive P-13 will cause The operators will manually trip the turbine a reactor trip

Question 66 A typographical error in the stem of the question, the noun name for MS-312A-1 referred to MSR B1 and B2, should have been MSR A1 and A2. Correct the error.

Original Question 66

66. Given the following:

- The unit was operating at 100% Rated Thermal Power when the reactor tripped.

- The crew has completed the required steps of E-O, "Reactor Trip or Safety Injection" and transitioned to ES-0.1, "Reactor Trip Response

- Main Steam Isolation Valves are OPEN

- The Balance of Plant Operator reports:

MS-312A-1, Gland Seal Steam to MSR B 1 & B2 Relief Vlvs is OPEN

MS-312B-1, Gland Seal Steam to MSR B 1 & B2 Relief Vlvs is CLOSED What actions will be required to mitigate this?

A. Condenser steam dump valves will be used for controlling RCS temperature to 350°F.

B. 'A' Train Condenser Steam Dump valves are still available for RCS temperature control.

C. Main Steam Isolation Valves will be closed to reduce the excessive cooldown of RCS temperature.

D. Steam Generator PORVs or Atmospheric Steam Dump valves will be used to control RCS temperature.

Question 66 with typo corrected:
