Q3 — RHR Suction and Discharge Alignment
005 RHRS-K1.09 (3.6)
Given:
Which ONE of the following completes the statement below?
The Residual Heat Removal System Pumps take suction from the _(1)_ Hot Leg and can be aligned to discharge into the _(2)_ Hot Legs.
Which ONE of the following completes the statement below?
The Residual Heat Removal System Pumps take suction from the _(1)_ Hot Leg and can be aligned to discharge into the _(2)_ Hot Legs.
A. (1) 21 — (2) 21 and 22
B. (1) 21 — (2) 23 and 24
C. (1) 22 — (2) 21 and 22
D. (1) 22 — (2) 23 and 24
▶ Show Answer & Explanation
✓ B. Correct. The Residual Heat Removal System Pumps take suction from the 21 Hot Leg and can be aligned to discharge into the 23 and 24 Hot Legs.
✗ A. Incorrect but plausible. Since the RHR Pumps take suction from an RCS hot leg and can be aligned to discharge into two RCS hot legs, selection of any combination of the 4 RCS loops is plausible.
✗ C. Incorrect but plausible. Since the RHR Pumps take suction from an RCS hot leg and can be aligned to discharge into two RCS hot legs, selection of any combination of the 4 RCS loops is plausible.
✗ D. Incorrect but plausible. Since the RHR Pumps take suction from an RCS hot leg and can be aligned to discharge into two RCS hot legs, selection of any combination of the 4 RCS loops is plausible.
