Plant Life Management is an industry initiative driven by the need to maximize the value and long-term profitability of nuclear plant assets. It integrates Aging Management with economic life cycle management of components.

The process of Aging Management has the objective to monitor and control degradation effects which may compromise safety functions of the plant. The target is the identification of possible degradation mechanisms for Systems, Structures and Components (SSCs) which are important to safety and to ensure that testing and maintenance programs sufficiently provide preventive or mitigative measures to control degradation effects. Aging Management covers mechanical components, electrical and I&C systems and components as well as civil structures and components.

AREVA has developed methodologies and software solutions to manage the life cycle of plant components and to optimize plant safety, availability, reliability and maintenance costs while meeting strategic business objectives. In order to support these activities, AREVA provides an integrated software platform which is provided to utilities on a licensing basis. The respective software platform is designed to manage aging issues and life cycle management activities.

This paper describes the AREVA methodologies and programs used to manage nuclear plant aging and to optimize plant safety, availability, reliability, and Operating & Maintenance costs in order to meet strategic business objectives.
