S2.OP-AR.ZZ-0012 — Console Alarm Response

⚠️ DRAFT — Reconstructed from exam materials

Purpose

Provides alarm response guidance for console alarms on Salem Unit 2, including the URGENT FAILURE alarm for the rod control system.

Key Alarms

URGENT FAILURE

  • All rod motion is inhibited in BOTH Manual and Automatic
  • Rods are held in position by the stationary gripper coil energized at reduced current
  • Moveable gripper coil is de-energized
Exam — 2023 Q55
Per S2.OP-AR.ZZ-0012, an Urgent Failure alarm prevents all rod motion in Manual or Automatic. Rods are held in position by the stationary gripper coil energized at reduced current. Moveable gripper coil is de-energized.

LOSS OF TRIPPING CAPABILITY (Bezel 4-17)

  • Indicates loss of power to the shunt trip coil for the affected RTB
  • Shunt coil is energized to trip — without power it cannot initiate a trip
  • UV (undervoltage) coil is de-energized to trip — it remains functional
  • 2CC2 RTB pushbuttons ONLY energize the shunt trip coil — they are non-functional when shunt coil power is lost
Exam — 2020 Q38
"LOSS OF TRIPPING CAPABILITY" alarm on RTB "A": the shunt trip coil will NOT be capable of opening RTB "A" because the alarm indicates loss of power to the shunt coil. UV trip coil remains functional (it de-energizes to trip). 2CC2 pushbuttons ONLY energize the shunt coil — with shunt coil power lost, they cannot trip the RTB.

PRIMARY WATER FLOW DEVIATION

Exam — 2018 Q31
Primary Water Flow Deviation Alarm setpoint: ±5.0 gpm above the setpoint. Boric Acid Flow Deviation alarm setpoint is ±0.8 gpm — common distractor.
Exam — 2019 Q3
Primary Water Flow Deviation Alarm setpoint: ±5.0 gpm above the setpoint. Boric Acid Flow Deviation alarm setpoint is ±0.8 gpm — do not confuse the two deviation alarm setpoints.
