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
