Abstract
This paper describes the background and status of a new International Network on “Incorporating Ageing Effects into Probabilistic Safety Assessment”. The Joint Research Centre (JRC) of the European Commission organized in September 2004 the kickoff meeting of this Network at JRC's Institute for Energy in Petten, Netherlands, with the aims to open the APSA Network, to start discussion of ageing issues in relation to incorporating ageing effects into PSA tools and to come to consensus on objectives and work packages of the Network, taking into account the specific expectations of potential Network partners. The presentations and discussions at the meeting confirmed the main conclusion from the previously organized PSAM7 pre-conference workshop on “Incorporating PSA into Ageing Management”, Budapest, June 2004, namely that incorporating ageing effects into PSA seems to be more and more a hot topic particularly for risk assessment and ageing management of nuclear power plants operating at advanced age (more than 25–30 years) and for the purpose of plant life extension. However, it also appeared that, especially regarding the situation in Europe, at present there are several on-going feasibility or full studies in this area, but not yet a completed Ageing PSA leading to applications. The project's working method is a NETWORK of operators, industry, research, academia and consultants with an active interest in the area (physical networking via a series of workshops and virtual networking via the Internet). The resulting knowledge should help PSA developers and users to incorporate the effects of equipment ageing into current PSA tools and models, to identify and/or develop most effective corresponding methods, to focus on dominant ageing contributors and components and to promote the use of PSA for ageing management of Nuclear Power Plants.
Kurzfassung
Dieser Artikel beschreibt den Hintergrund und Status eines neues internationalen Netzwerks zum Thema Berücksichtigung von Alterungseffekten in probabilistischen Sicherheitsanalysen (PSA). Die Gemeinschaftliche Forschungsstelle (GFS) der Europäischen Kommission organisierte im September 2004 das erste Treffen dieses Netzwerks am Energieinstitut der GFS in Petten in den Niederlanden, um das Netzwerk offiziell zu starten sowie einige für die Netzwerkpartner interessante Themenstellungen im Bereich „Alterungs-PSA“ (APSA) zu definieren. Es scheint, dass diese zur Zeit aufgrund alternder Kernkraftwerksanlagen immer aktuellere Thematik zwar mittels einiger Machbarkeitsstudien und erster Analysen angerissen, aber – insbesondere in Europa – bislang noch keine APSA durchgeführt wurde, die auch zu praktischen PSA Anwendungen geführt hätte. Die Arbeitsmethode des GFS APSA Projekts ist diejenige eines Netzwerks aus Vertretern von Betreibern, Industrie, Forschung, Universitäten sowie Konsulenten mit einem aktiven Interesse und bereits bestehendem Arbeitsprogramm in diesem Gebiet. Das durch dieses Netzwerk entwickelte Wissen soll PSA Entwicklern und Benutzern helfen, Alterungseffekte in bestehende PSA Modelle und Ansätze einzuarbeiten, effektive APSA Methoden zu identifizieren, sich auf dominante Alterungsbeiträge und Komponenten zu konzentrieren sowie allgemein die Verwendung von PSA fuer Alterungsmanagement von Kernkraftwerken zu fördern.
