G 2.2.17 (3.8)
Given:
• Unit 2 is at 100% Power.
• OHA H-27, GEN VREG TRBL, is LIT.
• PO reports that the main generator Automatic Voltage Regulator (AVR) swapped to Manual.
In accordance with OP-AA-108-107-1002, Salem and Hope Creek 500 KV Switchyard Operations Interface Procedure, which one of the following completes both statements?
1. The Shift Manager is required to notify _(1)_ that the AVR is not in AUTO.
2. Per S2.OP-AR.ZZ-0008, Overhead Annunciator Window H, the operating shift is required to make the notification within _(2)_ minutes of receiving OHA H-27.

▶ Show Answer & Explanation
✓ A. Correct. IAW OP-AA-108-107-1002 step 3.1.17, the operations shift notifies ESOC when the generator Automatic Voltage Regulator (AVR) is NOT in Automatic mode. Log the times when the station voltage regulation equipment is not in Automatic mode. Also, notifies the ER&T Generation Desk who will make appropriate notifications to PJM. IAW OHA H-27 ARP, 15 minute notification to ESOC is required.
✗ B. Part 1 is correct. Part 2 is incorrect. Plausible for 30 minutes since it's reasonable to believe that prompt notification of 15 minutes is not warranted for this condition.
✗ C. Part 1 is incorrect. Part 2 is correct. Plausible because the SRO does make notifications to the Hope Creek control room on conditions that may impact plant operations.
✗ D. Part 1 is incorrect. Part 2 is incorrect. Plausible because the SRO does make notifications to the Hope Creek control room on conditions that may impact plant operations. Plausible for 30 minutes since it's reasonable to believe that prompt notification of 15 minutes is not warranted for this condition.
