the discrepancy rather than defer, bypass, or redefine the control.
13. A reviewer finds conflicting evidence about Pressure, temperature, level and flow instrumentation with automatic-control principles with emphasis on
boundaries during a pre-task planning review. What should happen first? Case EB-2559-0013: 6 checks are complete, 3 item(s) remain open, 1 supporting
record(s) are available, the last review was 17 hour(s) ago, and the current result differs from the prior baseline by 7 unit(s).
A. Proceed using an estimate even though the approved method and current inputs are available.
B. Confirm source data and allowable limits for Pressure, temperature, level and flow instrumentation with automatic-control principles, repeat the calculation
with an independent check, and resolve any difference before acceptance.
C. Adjust an input until the result falls within the target range, then record only the final value.
D. Average the conflicting results and accept the midpoint without checking the source data.
Correct Answer: B
Explanation: The best answer verifies Pressure, temperature, level and flow instrumentation with automatic-control principles against current requirements and
evidence before acceptance. With 3 open item(s), 1 supporting record(s), and a 7-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
14. A reviewer finds conflicting evidence about Water treatment, corrosion, scale, blowdown and chemistry-control decisions for defensible calculations and
during a pre-task planning review. What should happen first? Case EB-2559-0014: 4 checks are complete, 4 item(s) remain open, 5 supporting record(s) are
available, the last review was 6 hour(s) ago, and the current result differs from the prior baseline by 5 unit(s).
A. Use the previous calculation unchanged even though one or more current inputs have changed.
B. Confirm source data and allowable limits for Water treatment, corrosion, scale, blowdown and chemistry-control decisions for defensible, repeat the
calculation with an independent check, and resolve any difference before acceptance.
C. Ignore unit or assumption differences if the final number appears reasonable.
D. Adjust an input until the result falls within the target range, then record only the final value.
Correct Answer: B
Explanation: The best answer verifies Water treatment, corrosion, scale, blowdown and chemistry-control decisions for against current requirements and
evidence before acceptance. With 4 open item(s), 5 supporting record(s), and a 5-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
15. A reviewer finds conflicting evidence about Startup, steady operation, load change, shutdown and abnormal-condition response including recognition of
abnormal during a pre-task planning review. What should happen first? Case EB-2559-0015: 2 checks are complete, 1 item(s) remain open, 2 supporting
record(s) are available, the last review was 19 hour(s) ago, and the current result differs from the prior baseline by 3 unit(s).
A. Confirm source data and allowable limits for Startup, steady operation, load change, shutdown and abnormal-condition response including, repeat the
calculation with an independent check, and resolve any difference before acceptance.
B. Average the conflicting results and accept the midpoint without checking the source data.
C. Select the most favorable result from repeated calculations without investigating the variation.
D. Ignore unit or assumption differences if the final number appears reasonable.
Correct Answer: A
Explanation: The best answer verifies Startup, steady operation, load change, shutdown and abnormal-condition response against current requirements and
evidence before acceptance. With 1 open item(s), 2 supporting record(s), and a 3-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
