EPE 38 G2.1.3 (3.7)
Given:
• Salem Unit 2 is experiencing a Steam Generator Tube Rupture
• The crew is performing actions per 2-EOP-SGTR-1, Steam Generator Tube Rupture
• The CRS, RO, and BOP operators are the only licensed operators in the control room
• The RO needs to go to the Control Equipment Room (back rack area) to perform an action
Per OP-AA-101-111, Roles and Responsibilities of On-Shift Personnel, which of the following describes the requirements for this activity?
• Salem Unit 2 is experiencing a Steam Generator Tube Rupture
• The crew is performing actions per 2-EOP-SGTR-1, Steam Generator Tube Rupture
• The CRS, RO, and BOP operators are the only licensed operators in the control room
• The RO needs to go to the Control Equipment Room (back rack area) to perform an action
Per OP-AA-101-111, Roles and Responsibilities of On-Shift Personnel, which of the following describes the requirements for this activity?
A. must be relieved by a licensed operator other than the on-shift Unit 2 BOP operator.
B. may leave as long as the on-shift Unit 2 BOP operator remains "At the Controls" area.
C. may leave without being relieved by another licensed operator with CRS permission ONLY.
D. must be relieved by another licensed operator and a full turnover must be performed.
▶ Show Answer & Explanation
✗ A. Incorrect. The requirement is that at least one RO remains in the ATC area, not that a specific relief must occur by a non-BOP licensed operator.
✓ B. Correct. Per OP-AA-101-111, at least one RO must be in the "At The Controls" (ATC) area (or inner-horseshoe) at all times during Modes 1-6, except for the time period required to acknowledge the receipt of an alarm outside this area or to perform actions required for safe plant operation. The BOP operator remaining in the ATC area satisfies this requirement.
✗ C. Incorrect. CRS permission alone is not sufficient — the requirement is that at least one licensed RO must remain in the ATC area. The BOP remaining in the ATC area satisfies this requirement regardless of CRS permission.
✗ D. Incorrect. A full turnover is not required for a brief departure from the ATC area. The requirement is simply that at least one licensed RO remains at the controls.
