Q41 — Troubleshooting Conduct
G2.2.20 (2.6)
Given:
• Unit 2 is at 100% Reactor Power
• Troubleshooting activities are in progress on CVCS
• Per the troubleshooting plan, some CVCS valves will be manipulated in order to gather data
In accordance with MA-AA-716-004 (CONDUCT OF TROUBLESHOOTING), which ONE of the following completes the statements below?
Manipulation of CVCS valves to support the troubleshooting plan is considered a(n) _(1)_ activity.
_(2)_ is responsible for ensuring the Troubleshooting Log adequately addresses the potential to affect core reactivity.
• Unit 2 is at 100% Reactor Power
• Troubleshooting activities are in progress on CVCS
• Per the troubleshooting plan, some CVCS valves will be manipulated in order to gather data
In accordance with MA-AA-716-004 (CONDUCT OF TROUBLESHOOTING), which ONE of the following completes the statements below?
Manipulation of CVCS valves to support the troubleshooting plan is considered a(n) _(1)_ activity.
_(2)_ is responsible for ensuring the Troubleshooting Log adequately addresses the potential to affect core reactivity.
A. (1) Intrusive (2) Operations
B. (1) Intrusive (2) Engineering
C. (1) Non-Intrusive (2) Operations
D. (1) Non-Intrusive (2) Engineering
▶ Show Answer & Explanation
✓ A. Correct. For Part 1 and IAW MA-AA-716-004 (CONDUCT OF TROUBLESHOOTING), Manipulation of CVCS valves to support the troubleshooting plan is considered a(n) Intrusive activity. For Part 2 and IAW MA-AA-716-004 (CONDUCT OF TROUBLESHOOTING), Operations is responsible for ensuring the Troubleshooting Log adequately addresses the potential to affect core reactivity.
✗ B. Part 1 is correct. For Part 2, Engineering has responsibilities per MA-AA-716-004 and Engineering performs Unreviewed Safety Questions screenings. Consequently, the candidate could incorrectly conclude that Engineering would do a USQ screening as part of the troubleshooting plan and the USQ screening would include a reactivity analysis.
✗ C. For Part 1, since the valve manipulations do not include breaking into the system, the candidate could incorrectly conclude that manipulation of valves is considered a Non-Intrusive Activity. Part 2 is correct.
✗ D. For Part 1, since the valve manipulations do not include breaking into the system, the candidate could incorrectly conclude that manipulation of valves is considered a Non-Intrusive Activity. For Part 2, Engineering has responsibilities per MA-AA-716-004 and Engineering performs Unreviewed Safety Questions screenings. Consequently, the candidate could incorrectly conclude that Engineering would do a USQ screening as part of the troubleshooting plan and the USQ screening would include a reactivity analysis.
