NANTeL Human Performance Principles 3

Question 1

Which best describes 'normalization of deviance' in nuclear operations?

Accepted Answer

Gradual acceptance of non-standard practices as normal over time

Answer

Normalization of deviance occurs when repeated exposure to deviations without negative consequence causes workers to accept those deviations as acceptable practice.

Question 2

The primary purpose of the nuclear Corrective Action Program (CAP) is to:

Accepted Answer

Identify, evaluate, and resolve conditions adverse to quality

Answer

The CAP provides a structured method to identify conditions adverse to quality and drive timely, effective corrective actions to prevent recurrence.

Question 3

A worker performing valve lineup verification should use 'place-keeping' because it:

Accepted Answer

Marks physical progress through a checklist to prevent omissions

Answer

Place-keeping physically tracks position in a procedure to prevent losing one's place during interruptions, which is a common cause of errors of omission.

Question 4

Which scenario is an example of a 'knowledge-based' error?

Accepted Answer

Applying incorrect knowledge to diagnose an unfamiliar plant transient

Answer

Knowledge-based errors occur when a person must reason through an unfamiliar situation and applies incorrect or incomplete mental models to solve it.

Question 5

The concept of 'conservative decision-making' in nuclear operations means:

Accepted Answer

Choosing the option that best preserves safety margin when uncertain

Answer

Conservative decision-making means that when facing uncertainty, the worker selects the option that maintains the greatest safety margin and avoids unnecessary risk.
