2019 Q16 — AFW Pump Start with Local Manual

✓ C. Correct. With ALL of the AFW Pump Controllers in LOCAL MANUAL, all automatic AFW starts are disabled except those starts initiated from by the SECs. At 12:00 when the Safety Injection occurs, the SECs will actuate in Mode 1 which will send an automatic start signal to ONLY 21 and 22 AFW pumps. Consequently, at 12:05, ONLY 21 and 22 AFW pumps are running.

✗ A. The candidate could correctly determine that with ALL of the AFW Pump Controllers in LOCAL MANUAL, all automatic AFW starts are disabled except those starts initiated from by the SECs. The candidate could then incorrectly conclude that ALL of the AFW pumps receive an automatic start signal from the SECs which would then cause the candidate to incorrectly conclude at 12:05, ALL AFW Pumps are running.

✗ B. The candidate could incorrectly conclude that with ALL of the AFW Pump Controllers in LOCAL MANUAL, all automatic AFW starts are disabled (including those starts initiated from by the SECs). This would then cause the candidate to incorrectly conclude at 12:05, NO AFW Pumps are running.

✗ D. The candidate could correctly determine that with ALL of the AFW Pump Controllers in LOCAL MANUAL, all automatic AFW starts are disabled except those starts initiated from by the SECs. The candidate could then incorrectly conclude that ONLY 23 AFW pump receives an automatic start signal from the SECs which would then cause the candidate to incorrectly conclude at 12:05, ONLY 23 AFW Pump is running.
