B. (1) are (2) and to the RVLIS Electronics Cabinets
C. (1) are NOT (2) ONLY
D. (1) are NOT (2) and to the RVLIS Electronics Cabinets
▶ Show Answer & Explanation
✓ B. Correct. For Part 1 and IAW LCO 3.3.3.7 (ACCIDENT MONITORING INSTRUMENTATION), 2PT-403 (RCS Narrow Range Pressure) and 2PT-405 (RCS Wide Range Pressure) are credited as accident monitoring instrumentation. For Part 2, 2PT-403 and 2PT-405 provide input to the Pressurizer Overpressure Protection System (POPS) and to the RVLIS Electronics Cabinets.
✗ A. Part 1 is correct. For Part 2, the candidate could incorrectly conclude that 2PT-403 and 2PT-405 provide input to the Pressurizer Overpressure Protection System (POPS) ONLY.
✗ C. The candidate could incorrectly conclude that In accordance with Unit 2 LCO 3.3.3.7 (ACCIDENT MONITORING INSTRUMENTATION), 2PT-403 (RCS Pressure) and 2PT-405 (RCS Pressure) are not credited as accident monitoring instrumentation. For Part 2, the candidate could incorrectly conclude that 2PT-403 and 2PT-405 provide input to the Pressurizer Overpressure Protection System (POPS) ONLY.
✗ D. The candidate could incorrectly conclude that In accordance with Unit 2 LCO 3.3.3.7 (ACCIDENT MONITORING INSTRUMENTATION), 2PT-403 (RCS Pressure) and 2PT-405 (RCS Pressure) are not credited as accident monitoring instrumentation. Part 2 is correct.
