⚠️ DRAFT
Q36 — FHB Ventilation 2R9 Alarm 072 ARM-G2.4.31 (4.2)
Given:

• 21 Fuel Handling Area Exhaust Fan is in service
• 22 Fuel Handling Area Exhaust Fan is in standby
• 21 HEPA ONLY Filter Unit is in service
• HEPA 22 PLUS CHAR is in standby

At time 17:00
• 2R9 (Fuel Storage Area Monitor) goes into alarm

Which ONE of the following completes the statement below?

Five Minutes later at 17:05, _(1)_ Fuel Handling Area Exhaust Fan(s) and _(2)_ Filter Unit(s) is/are in service.

(1)(2)
A. (1) ONLY 21 — (2) ONLY HEPA 22 PLUS CHAR
B. (1) ONLY 21 — (2) 21 HEPA ONLY AND HEPA 22 PLUS CHAR
C. (1) 21 and 22 — (2) ONLY HEPA 22 PLUS CHAR
D. (1) 21 and 22 — (2) 21 HEPA ONLY AND HEPA 22 PLUS CHAR
▶ Show Answer & Explanation
✓ C. Correct. When 2R9 goes into alarm, BOTH Fuel Handling Area Fans receive an auto start signal and 21 HEPA ONLY Filter Unit Isolates while 22 HEPA PLUS CHAR filter unit automatically aligns. Consequently, at 17:05, 21 and 22 Fuel Handling Area Fans and ONLY HEPA 22 PLUS CHAR Filter Unit are in service.
✗ A. Incorrect but plausible. For Part 1, the candidate could incorrectly conclude that only the running fan (21) will be in service at 17:05. Part 2 is correct.
✗ B. Incorrect but plausible. For Part 1, the candidate could incorrectly conclude that only the running fan (21) will be in service at 17:05. For Part 2, the candidate could incorrectly conclude that BOTH HEPAs will be in service at 17:05.
✗ D. Incorrect but plausible. Part 1 is correct. For Part 2, the candidate could incorrectly conclude that BOTH HEPAs will be in service at 17:05.
