• The crew has just entered 2-EOP-FRSM-1, Response to Nuclear Power Generation – ATWS.
• The below Caution symbol appears prior to step 1.
In accordance with OP-SA-108-101-2002, Emergency Operating Procedure User’s Guide, which ONE of the following completes the statement?
Because the Caution appears before step 1, the Caution __________________.
A. provides no instruction or operator action, only information to support the operator action
B. applies only to step 1
C. applies to step 1 and may apply to subsequent procedure steps
D. informs the operator of an action that must be taken if conditions are met at any time while in the procedure
▶ Show Answer & Explanation
✓ C. Correct. IAW OP-SA-108-101-2002 section 2.15 (Notes and Cautions), Cautions contain information about potential hazards to personnel or equipment. They also advise on action or transitions which may become necessary depending on changes in plant conditions. Based on the symbol (double borders) in the stem, this is a Continuous Caution. Per step 2.15.12, a Continuous Caution which precedes the first operator action step may also apply to the entire EOP guideline.
✗ A. Incorrect. Plausible if the operator believes this is the description of a Caution but it is a description of a Note used in EOPs.
✗ B. Incorrect. Plausible if the operator believes this is a Caution symbol (single border) versus a Continuous Caution symbol (double border). This Caution will only apply to the step it preceded and not throughout the EOP.
✗ D. Incorrect. Plausible if the operator believes this is the description of a Caution, but it is a description of a continuous action step used in EOPs.
