 Abstract: The units 3&4 of US Turkey Point Nuclear Plant are the world’s first nuclear power units which obtained approval for extended operation to 80-year lifetime. This paper introduces the aging management reviews for reactor coolant system and its connected piping of the two units, including the screening of passive and long-life components and their indications in the boundary diagrams. After ranking the sets of components, intended functions, materials, environment and aging effects, the aging management review items are determined, and whether appropriate aging management programs are provided to cope with is reviewed. The evaluation conclusion of NRC staff is presented.
