Q68 — Fuel Handling Incident Canal Gate Valve
APE 036 Fuel Handling Incidents-AK3.02 (2.9)
Given:
• The crew is performing S2.OP-AB.FUEL-0001 (FUEL HANDLING INCIDENT) due to a fuel incident inside containment
• The canal gate valve is open
In accordance with S2.OP-AB.FUEL-0001, which ONE of the following completes the statement below?
The crew _(1)_ required to close the canal gate valve.
The canal gate valve can ONLY be FULLY closed with the fuel transfer cart _(2)_.
• The crew is performing S2.OP-AB.FUEL-0001 (FUEL HANDLING INCIDENT) due to a fuel incident inside containment
• The canal gate valve is open
In accordance with S2.OP-AB.FUEL-0001, which ONE of the following completes the statement below?
The crew _(1)_ required to close the canal gate valve.
The canal gate valve can ONLY be FULLY closed with the fuel transfer cart _(2)_.
A. (1) is NOT (2) inside containment
B. (1) is NOT (2) in the Fuel Handling Building
C. (1) is (2) inside containment
D. (1) is (2) in the Fuel Handling Building
▶ Show Answer & Explanation
✓ C. Correct. For Part 1 and IAW S2.OP-AB.FUEL-0001, the canal gate valve will be closed for any fuel handling incident (Step 3.16). For Part 2, there is a mechanical interlock that allows the canal gate valve to be fully closed only when the fuel transfer cart is inside containment.
✗ A. Incorrect but plausible. For Part 1, since the FHB ventilation and containment ventilation are designed to handle a fuel handling incident, the candidate could incorrectly conclude that S2.OP-AB.FUEL-0001 does not require the canal gate valve to be closed. Part 2 is correct.
✗ B. Incorrect but plausible. For Part 1, since the FHB ventilation and containment ventilation are designed to handle a fuel handling incident, the candidate could incorrectly conclude that S2.OP-AB.FUEL-0001 does not require the canal gate valve to be closed. For Part 2, the candidate could incorrectly determine that the canal gate valve can ONLY be FULLY closed with the fuel transfer cart in the Fuel Handling Building.
✗ D. Incorrect but plausible. Part 1 is correct. For Part 2, the candidate could incorrectly determine that the canal gate valve can ONLY be FULLY closed with the fuel transfer cart in the Fuel Handling Building.
