Q95 — PORV Block Valve Configuration Control
G2.2.14 (3.2)
Given:
• Unit 2 is at 100% Power
At time 17:55
• An LCO 3.4.5 (RELIEF VALVES) REQUIRED ACTION has been entered due to a failure of the 2PR2 (PZR PORV) control circuitry.
• 2PR7 (PZR PORV BLOCK VALVE) will be closed to comply with LCO 3.4.5 (RELIEF VALVES) REQUIRED ACTION B
Which ONE of the following completes the statement below?
In accordance with LCO 3.4.5 and after 2PR7 has been closed, power will be _(1)_ to 2PR7 and in accordance with OP-AA-108-101-1002 (COMPONENT CONFIGURATION CONTROL), configuration control will be INITIALLY maintained with a(n) _(2)_.
• Unit 2 is at 100% Power
At time 17:55
• An LCO 3.4.5 (RELIEF VALVES) REQUIRED ACTION has been entered due to a failure of the 2PR2 (PZR PORV) control circuitry.
• 2PR7 (PZR PORV BLOCK VALVE) will be closed to comply with LCO 3.4.5 (RELIEF VALVES) REQUIRED ACTION B
Which ONE of the following completes the statement below?
In accordance with LCO 3.4.5 and after 2PR7 has been closed, power will be _(1)_ to 2PR7 and in accordance with OP-AA-108-101-1002 (COMPONENT CONFIGURATION CONTROL), configuration control will be INITIALLY maintained with a(n) _(2)_.
A. (1) maintained (2) Work Clearance Document (WCD)
B. (1) maintained (2) Abnormal Component Position Sheet (ACPS)
C. (1) removed (2) Work Clearance Document (WCD)
D. (1) removed (2) Abnormal Component Position Sheet (ACPS)
▶ Show Answer & Explanation
✓ D. Correct. For Part 1 and IAW LCO 3.4.5, after 2PR7 has been closed, power will be removed to 2PR7. For Part 2 and IAW OP-AA-108-101-1002 (COMPONENT CONFIGURATION CONTROL), an Abnormal Component Position Sheet (ACPS) will be used to position 2PR7 since removing power from 2PR7 is a 1 hour or less TS REQUIRED ACTION.
✗ A. Incorrect but plausible. For Part 1, if 2PR7 was inoperable due to excess seat leakage, the power would be maintained to 2PR7 (IAW LCO 3.4.5). For Part 2 and IAW OP-AA-108-101-1002, a WCD will be hung on the components as soon as practical after the TS is entered.
✗ B. Incorrect but plausible. For Part 1, if 2PR7 was inoperable due to excess seat leakage, the power would be maintained to 2PR7 (IAW LCO 3.4.5). Part 2 is correct.
✗ C. Incorrect but plausible. Part 1 is correct. For Part 2 and IAW OP-AA-108-101-1002, a WCD will be hung on the components as soon as practical after the TS is entered.
