Question #1 Given the following plant conditions:
- A Reactor Coolant System (RCS) Leak has occurred at the weld connection of the Pressurizer Spray line connection at the top of the Pressurizer
- A reactor trip has occurred and the crew is responding in accordance with E-0, Reactor Trip or Safety Injection Which one of the following describes when and why the Reactor Coolant Pumps (RCP) would be tripped?
When RCS pressure lowers to less than 1425 psig with A. at least one CCP running, to reduce RCS inventory loss.
B. NO ECCS pumps running, to reduce RCS inventory loss.
C. at least one CCP running, to prevent RCP motor damage from containment conditions.
D. NO ECCS pumps running, to prevent RCP motor damage from containment conditions.
Answer: A Explanation:
A. Correct. This is directed by the RCP Trip Criteria found on the Foldout Page of E-0. The basis of this direction is to minimize the loss of RCS inventory during a SBLOCA which is the pressurizer vapor space accident described in the question.
B. Incorrect. Reason is correct but ECCS pump status is not correct. With no ECCS pumps running, the RCPs are required to ensure core heat removal.
NRC Site-Specific Written Examination Callaway Plant Reactor Operator C. Incorrect. Incorrect reason given to prevent RCP motor damage. This reason is plausible as the containment will be in a very humid condition but this is not a concern for securing the RCPs. RCS pressure and CCP status is correct.
D. Incorrect. Incorrectly states this can be done with no ECCS pumps running. Also has incorrect reason given to prevent RCP motor damage. This reason is plausible as the containment will be in a very humid condition but this is not a concern for securing the RCPs.

B. TRIP on Low Pressurizer Pressure of 1885 psig.
C. TRIP on High Pressurizer Pressure of 2385 psig.
D. TRIP when Safety Injection actuates at 1849 psig.
Answer: D Explanation:
A. Incorrect. Answer is plausible since the given power level will block the low pressure trip but will not block the SI pressure trip at 1849 psig.
B. Incorrect. RCS pressure will lower, but the trip is blocked at this power level due to being below the P-7 setpoint of 10%.
C. Incorrect. PT-457 failing high causes the pressurizer spray valves to open, thus RCS pressure will lower rather than rise.
D. Correct. The pressurizer spray valves will open due to 457 failing high causing RCS pressure to lower.
The low pressure reactor trip is blocked by P-7. Pressure will lower to the SI setpoint at which time the SI signal will cause a reactor trip.

A. It is performed to minimize void formation in the reactor core.
B. It is performed to add negative reactivity to bring the reactor core subcritical.
C. It is the fastest mechanism for adding negative reactivity to the reactor core.
D. It is the ONLY means available to shut down the reactor if the manual reactor trip pushbuttons do not function.
Answer: B Explanation:
A. Incorrect. Plausible as emergency boration is adding a volume of borated water to the RCS that would help fill any voids that might be created due to the failure to trip. Per the background document for FR-S.1, emergency boration is performed to ensure the reactor is subcritical, not to minimize void formation.
B. Correct. Per BD-FR-S.1, Response To Nuclear Power Generation/ATWS, the purpose of emergency boration is to add negative reactivity to bring the reactor core subcritical.
C. Incorrect. It is not the fastest method to add negative reactivity; the fastest method is to insert rods.
D. Incorrect. It is not the only means. Other available options are inserting the control rods in manual and opening the PG breakers to allow rods to fall into the core.
