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).
