NANTeL - National Academy for Nuclear Training e-Learning Conduct of Operations Questions and Answers

Question 1

An operator is preparing to perform a valve alignment using a 'Continuous Use' procedure. Which of the following actions best demonstrates correct procedure adherence for this level of use?

Accepted Answer

Keeping the procedure in hand and reading each step immediately before performing that specific action.

Answer

A 'Continuous Use' (or 'In Hand') procedure classification requires the user to read each step immediately prior to performing it. This ensures that each action is performed correctly and in the proper sequence, minimizing reliance on memory for critical tasks.

Question 2

During a shift turnover, the oncoming Control Room Operator identifies a discrepancy between the turnover checklist and the control board status for a safety-related pump. The offgoing operator states it's a minor documentation lag and the board is correct. What is the most appropriate immediate action for the oncoming operator?

Accepted Answer

Formally refuse to accept the turnover until the discrepancy is resolved and documented by walking down the system or verifying its status through other means.

Answer

A core principle of Conduct of Operations is that shift turnover is a formal, deliberate process to ensure the oncoming shift has a complete and accurate understanding of plant status. Discrepancies must be resolved *before* the turnover is complete. Refusing to accept the watch until the inconsistency is properly investigated and documented ensures a safe and proper transfer of responsibility.

Question 3

Which of the following is the final, essential step in the three-way communication protocol after an instruction has been given and repeated back?

Accepted Answer

The sender confirms the repeat-back is correct by stating, "That is correct."

Answer

Three-way communication consists of three parts: 1) The sender states the message. 2) The receiver repeats back the message to demonstrate understanding. 3) The sender provides confirmation that the repeated message was correct (e.g., "That is correct"). This final confirmation closes the communication loop and ensures mutual understanding before an action is taken.

Question 4

A maintenance supervisor observes a team preparing for a high-risk job. Although all team members are experienced, the supervisor insists they conduct a detailed pre-job brief. What is the primary purpose of this Conduct of Operations tool?

Accepted Answer

To ensure the entire team shares a common understanding of the task, risks, contingencies, and individual roles.

Answer

The primary purpose of a pre-job brief is to ensure the work team is aligned. It involves discussing the scope of work, hazards, controls, roles, and stop-work criteria. This practice enhances safety and efficiency by creating a shared understanding and reinforcing a questioning attitude, even among experienced personnel.

Question 5

Which of the following best exemplifies the principle of 'Conservative Decision Making' in nuclear operations?

Accepted Answer

Placing the plant in a known, safe condition when faced with uncertain or unexpected plant parameters.

Answer

Conservative decision making prioritizes safety above all else. When operators face conditions that are not fully understood or are unexpected, the safest course of action is to place the plant in a stable and secure state (e.g., reducing power, shutting down) until the situation can be properly diagnosed. This approach builds in safety margins to account for uncertainties.
