Accident Sequence Precursor (ASP)

An Accident Sequence Precursor (ASP) is a warning indicator that suggests a nuclear plant is close to a potential accident, based on specific events or conditions observed during operation. It helps plant operators and safety analysts identify situations that could lead to a serious incident if not addressed promptly. By monitoring these precursors, they can take preventive actions before a major accident occurs, enhancing overall safety and preventing damage to the plant and surrounding environment.
