▶ Show Answer & Explanation
✓ C. Correct. For Part 1 and IAW S2.OP-SO.WL-0002, during the release, 21 CVCS MT is being released via SW to CW. For Part 2 and IAW S2.OP-SO.WL-0001 Step 5.5.8, the crew is required to stop the release when 2FR1064 (RADWASTE OVERBOARD DISCH FLOW RECORDER) becomes inoperable.
✗ A. For Part 1, the candidate could incorrectly conclude that the release will be via SW ONLY. Part 2 is correct.
✗ B. For Part 1, the candidate could incorrectly conclude that the release will be via SW ONLY. For Part 2, the candidate could fail to recognize that 2FR1064 (RADWASTE OVERBOARD DISCH FLOW RECORDER) is required for the liquid waste release. Consequently, the candidate could incorrectly conclude that at 1200, the crew is NOT required to stop the release.
✗ D. Part 1 is correct. For Part 2, the candidate could fail to recognize that 2FR1064 (RADWASTE OVERBOARD DISCH FLOW RECORDER) is required for the liquid waste release. Consequently, the candidate could incorrectly conclude that at 1200, the crew is NOT required to stop the release.
