NANTeL - National Academy for Nuclear Training e-Learning Conduct of Operations Questions and Answers 1 — 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?
- Reviewing the procedure in the control room, then performing the entire alignment from memory at the job site.
- Keeping the procedure in hand and reading each step immediately before performing that specific action. (Correct answer)
- Performing the familiar initial steps from memory and then referring to the procedure for the critical final steps.
- Having a coworker read the steps aloud while the operator performs the actions without looking at the procedure.
Correct answer: Keeping the procedure in hand and reading each step immediately before performing that specific action.
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?
- Accept the verbal explanation and sign the turnover sheet to allow the offgoing shift to leave on time.
- Correct the checklist to match the board status and then complete the turnover.
- 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. (Correct answer)
- Note the discrepancy in their personal log and plan to investigate it after the offgoing shift has departed.
Correct 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.
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?
- The receiver says "Roger" to indicate the message was heard.
- The sender confirms the repeat-back is correct by stating, "That is correct." (Correct answer)
- The receiver documents the communication in the control room log.
- The sender and receiver both initial a communication checklist.
Correct answer: The sender confirms the repeat-back is correct by stating, "That is correct."
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?
- To fulfill a regulatory paperwork requirement before work can begin.
- To give the supervisor an opportunity to assign blame if an error occurs.
- To ensure the entire team shares a common understanding of the task, risks, contingencies, and individual roles. (Correct answer)
- To test the team's knowledge by having them recite the procedure from memory.
Correct answer: To ensure the entire team shares a common understanding of the task, risks, contingencies, and individual roles.
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?
- Choosing the fastest method to complete a repair to minimize equipment downtime.
- Assuming an ambiguous instrument reading is an error and waiting for it to self-correct.
- Placing the plant in a known, safe condition when faced with uncertain or unexpected plant parameters. (Correct answer)
- Strictly following a procedure even when it appears to be leading to an undesirable plant response.
Correct answer: Placing the plant in a known, safe condition when faced with uncertain or unexpected plant parameters.
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.
Question 6: An Auxiliary Operator performing routine rounds identifies an oil leak on a non-safety-related pump that was not present on the previous shift. According to the principles of Conduct of Operations, what is the operator's immediate responsibility?
- Clean up the oil to prevent a slip hazard and continue with the rounds.
- Attempt to tighten the fittings on the pump to stop the leak.
- Make a note to inform the maintenance department at the end of the shift.
- Promptly notify the control room or shift supervisor of the change in equipment condition. (Correct answer)
Correct answer: Promptly notify the control room or shift supervisor of the change in equipment condition.
A fundamental aspect of Conduct of Operations is maintaining a high level of situational awareness and formally communicating any changes in facility status. Operators are the eyes and ears of the plant, and prompt notification to the control room or supervision about any abnormal condition, regardless of the system's safety classification, is critical for proper evaluation and response.
