Q66 — Stator Water Cooling / Unit 1 vs Unit 2 Differences
T3 G2.2.3 (3.8)
Which of the following completes the statement concerning Salem Unit 1 vs. Unit 2 Stator Water Cooling System design?
Salem Unit (1) is the ONLY unit that has an automatic Turbine Runback feature when the following stator water system condition(s) exist; (2) .
Salem Unit (1) is the ONLY unit that has an automatic Turbine Runback feature when the following stator water system condition(s) exist; (2) .
A. (1) 1 (2) low flow, low pressure, or high temperature
B. (1) 2 (2) low flow, low pressure, or high temperature
C. (1) 2 (2) low flow Only
D. (1) 1 (2) low flow Only
▶ Show Answer & Explanation
✓ B. Correct. Salem Unit 2 is the only unit that has an automatic turbine runback when any of the following conditions exist; low flow, low pressure, and high temperature.
✗ A. Part 1 is incorrect. Plausible because the operator may confuse which unit has this design feature. Part 2 is correct.
✗ C. Part 1 is correct. Part 2 is incorrect. Plausible because this condition is used on both units, but unit 2 uses it for the turbine runback whereas unit 1 uses it for a turbine trip feature only.
✗ D. Part 1 is incorrect. Plausible because the operator may confuse which unit has this design feature. Part 2 is incorrect. Plausible because this condition is used on both units, but unit 2 uses it for the turbine runback whereas unit 1 uses it for a turbine trip feature only.
