• The crew is implementing the Critical Safety Function Status Trees
• SPDS indicates the following: [SPDS display showing CONTAINMENT ENVIRONMENT status — image in exam PDF]
Assuming the Critical Safety Function Status Trees have been verified, which ONE of the following completes the statement below?
SPDS indicates that CONTAINMENT ___
A. Pressure is ~47 psig
B. Radiation is ~2 R/HR
C. Sump level is ~78% (75% ADVERSE)
D. Pressure is ~15 psig and <47 psig and AT LEAST one Containment Spray Pump is running
▶ Show Answer & Explanation
✓ C. Correct. IAW EOP-CFST-1 and SPDS, FRCE-2 entry conditions are met. FRCE-2 is performed when Containment Sump level is ~78% (75% ADVERSE).
✗ A. Containment Pressure, Containment Sump Pump status and Containment Radiation are parameters that can cause entry conditions to FRCE-1 (Red), FRCE-1 (Purple) and FRCE-3 (Yellow) to be met. Consequently, all of the distractors are plausible.
✗ B. Containment Pressure, Containment Sump Pump status and Containment Radiation are parameters that can cause entry conditions to FRCE-1 (Red), FRCE-1 (Purple) and FRCE-3 (Yellow) to be met. Consequently, all of the distractors are plausible.
✗ D. Containment Pressure, Containment Sump Pump status and Containment Radiation are parameters that can cause entry conditions to FRCE-1 (Red), FRCE-1 (Purple) and FRCE-3 (Yellow) to be met. Consequently, all of the distractors are plausible.
