Which aspect of nuclear power plants is improved by incorporating passive safety features?

Incorporating passive safety features in nuclear power plants significantly enhances the likelihood of human error management. Passive safety systems are designed to function without the need for active intervention or external power sources. This reduces the reliance on human control and minimizes the potential for mistakes during operation. Essentially, these features automatically ensure safe conditions in the event of an emergency, thereby lessening the burden on operators.

By utilizing natural forces, such as gravity and convection, these systems can maintain safe temperatures and pressures without complex mechanical systems that may require constant human oversight. This design philosophy inherently addresses human error, as it creates scenarios where the system's safety is augmented through its ability to self-regulate, rather than solely depending on human action or decision-making.

While other aspects such as risks of terrorist attacks, control rod retraction, and design flaws are certainly critical considerations in the context of nuclear power, they do not directly relate to the primary advantage provided by passive safety systems, which is specifically aimed at mitigating human error in reactor operation and emergency response.
