Strategic alliance to address safety system obsolescence and maintainability

This paper describes a joint EPRI/Utility/Supplier project for evaluating the Reactor Protection Systems and Plant Protection Systems at Combustion Engineering (C-E) operating plants. The goal of the project is the development of long term maintenance plans that will solve obsolescence problems and extend the systems' useful life. Solutions developed under this project could be applied generically to other plant systems. The paper will describe each of the five phases of the project including: data collection and analysis; development of obsolescence evaluations and solutions; development of maintenance support evaluations and plans; development of long term plans for participating plants; development of a generic methodology for I&C obsolescence and maintainability evaluations.<>
