Safety limits are established to:

Safety limits are established to:

• A. Minimize operator workload
• B. Ensure the integrity of the fission product barriers
• C. Maximize fuel burnup
• D. Ensure plant availability

Answer: (D)

Safety limits define the maximum values for key reactor parameters to ensure the fission product barriers stay intact. These limits come from safety analyses and set the operating envelope that prevents fuel damage and radioactive releases. By keeping the plant within these bounds, the system maintains the barriers that protect public health and the environment and ensures the facility can be shut down safely and cooled effectively. While availability and operator workload are important considerations, they aren’t the primary purpose of safety limits; burnup is a fuel-management objective, not the driver for establishing these limits.
