Abstract

It is possible that many NPPs will be able to operate longer than their operational design lives, provided appropriate and proven ageing management measures are implemented in a timely manner. As a result, attention from the regulators and the utilities has been focused on the ageing of buildings and infrastructures of NPPs. In Europe approximately a third of the operational reactors are within a few years of, or older than, their original design lifetimes. In Finland, the VVER reactors have been granted a licence extension up to 50 years of operation, whereas the BWR reactors operating license has been renewed for a 60 year lifetime. All reactors have to be subject to a safety evaluation every 10 years. Strategies to manage and reduce the consequences of the concrete infrastructure ageing are also currently under development in many fields of civil engineering. Here is presented the MANAGE research project (funded by SAFIR2014). In this project an ageing management platform (AMP) has been developed for Finnish NPPs. The AMP consists of the central database and a group of analysing and planning tools which interact with the database. Both can be used during different phases in the lifetime of a plant: design, operation, inspection, monitoring, maintenance and repair of structures. The AMP consists of the following applications: document archive visualization; condition assessment database (archived reports and documents, inspection reports, etc.); and service-life assessment (ServiceMan).
