NANTeL Human Performance Principles 5

Question 1

Which statement BEST describes the role of 'self-checking' (STAR) versus 'peer-checking' in human performance?

Accepted Answer

Self-checking is an individual discipline while peer-checking adds an independent verification

Answer

Self-checking replaces peer-checking for routine tasks

Answer

Both techniques serve the same purpose and are interchangeable

Answer

Peer-checking is required by procedure; self-checking is optional

Question 2

A plant operator notices that a procedure step directs them to open a valve, but opening it would violate a technical specification limit condition for operation (LCO). The operator should:

Accepted Answer

Stop and immediately notify the shift supervisor before proceeding

Answer

Follow the procedure as written since it was approved by engineering

Answer

Open the valve and then notify the shift supervisor

Answer

Cross out the step and continue with the remaining steps

Question 3

In human performance, 'attention capture' (also called fixation) most commonly causes workers to:

Accepted Answer

Focus exclusively on one aspect of a task while missing broader plant conditions

Answer

Perform tasks faster than usual due to heightened focus

Answer

Correctly identify the root cause of a plant transient

Answer

Follow procedures more strictly during unusual events

Question 4

Which action BEST supports a strong nuclear safety culture regarding human performance?

Accepted Answer

Consistently applying human performance tools even when time is available and risk seems low

Answer

Rewarding teams that complete work fastest regardless of tool use

Answer

Discouraging workers from raising concerns that cannot be immediately resolved

Answer

Applying extra scrutiny only to new or inexperienced workers

Question 5

The concept of 'error-likely situations' in NANTeL human performance training refers to:

Accepted Answer

Specific combinations of task, worker, and environmental conditions that predictably increase error risk

Answer

Tasks performed only by workers with a history of errors

Answer

Procedures that have been identified as out-of-date

Answer

Equipment known to have design vulnerabilities

Question 6

When an unexpected plant response occurs during a procedure, the first priority for the operator is to:

Accepted Answer

Stop, assess the plant status, and notify supervision

Answer

Continue the procedure to reach a stable endpoint

Answer

Immediately identify and correct the root cause

Answer

Refer to the abnormal operating procedure without stopping

Question 7

Which leadership behavior MOST effectively reinforces human performance standards on the floor?

Accepted Answer

Performing periodic walk-downs and coaching on tool use in the field

Answer

Completing all error investigations behind closed doors

Answer

Posting performance metrics in break rooms

Answer

Holding monthly training sessions on human performance theory
