ANO-1 Experiences Using Structural Tools During License Renewal Application Available to Purchase

Arkansas Nuclear One, Unit 1 (ANO-1) submitted an application to the Nuclear Regulatory Commission (NRC) to extend its operating license for an additional 20 years on January 31, 2000. NRC regulations governing the license renewal process require the preparation of an Integrated Plant Assessment (IPA) to demonstrate that the effects of aging on systems, structures and components (SSCs) at ANO-1 are adequately managed. ANO participated in the B&W (now Framatome) Owners Group (BWOG) Generic License Renewal Program (GLRP) in developing the B&WOG “Aging Effects for Structures and Structural Components”, commonly referred to the “Structural Tools”. The Structural Tools (Mechanical and Electrical Tools are also available) is a generic evaluation based on material and environments that assist the user in performing an evaluation of aging effects. Using the Tools, considerable time was saved in preparing Aging Management Review Reports (AMRR) since the reviewer did not have to independently research potential causes of aging effects for the materials and environments being reviewed. This paper summarizes the ANO-1 experiences in preparing AMRRs utilizing the Structural Tools.
