Abstract

Abandonment of equipment is a fact of life for an aging nuclear station. Whether this equipment is no longer needed, cannot be removed during a modification, remains in place due to economic considerations or other reasons, the continued existence of abandoned equipment poses design, maintenance and operational challenges for the remaining life of the station. Operational Experience has shown a number of incidents when improperly abandoned equipment or system has resulted in significant safety events. This presentation cites some real life examples to highlight the importance of properly abandoning equipment and discusses a proposed methodology.
