AI in Nuclear Power Plant Operations Quiz

Answers and explanations appear as you take the quiz.

1. Where is AI most commonly used in current commercial nuclear plants?
   • Directly controlling reactor power
   • In advisory, non-safety functions such as maintenance analytics and document work
   • Replacing licensed reactor operators
   • Running the reactor protection system
2. What does online monitoring with redundant sensors mainly detect?
   • Changes in fuel prices
   • Staff attendance
   • Local weather
   • Sensor calibration drift
3. Why are semi-supervised methods common for plant anomaly detection?
   • Regulators ban labeled data
   • Plant sensors do not record history
   • Failures are rare, so labeled fault data is scarce
   • They are always faster to compute
4. In an auto-associative monitoring model, what signals a possible problem?
   • A significant residual between predicted and measured sensor values
   • Perfect agreement between the model and sensors
   • A sensor being switched off for maintenance
   • An operator logging into the control room
5. What is the sequential probability ratio test used for in this context?
   • Scheduling refueling outages
   • Drafting license amendments
   • Encrypting plant data
   • Testing residuals statistically to decide whether a sensor or component is drifting
6. Why are retrieval-augmented language tools preferred for nuclear documentation work?
   • They are cheaper to host
   • They cite source documents so reviewers can trace claims to controlled records
   • They need no human review
   • They can operate the reactor
7. Which body licenses commercial nuclear plants and operators in the United States?
   • The Nuclear Regulatory Commission
   • The Federal Aviation Administration
   • The Environmental Protection Agency alone
   • The International Atomic Energy Agency directly
8. Why are AI-assisted refueling outage planning tools valuable?
   • Outages are not regulated
   • Plants refuel every day
   • Thousands of tasks must be scheduled and every day offline costs money
   • They replace required inspections
