Risk and lifetime analysis methods for structural systems and components of power plants

Lifetime analyses of structural systems and components of power plants necessitate a thorough knowledge of structural properties, loads, the relevant ageing mechanisms and prevailing environmental conditions. Due to distributed nature of many of these properties or phenomena, probabilistic modelling methods are deemed suitable for the lifetime analyses. System or component failure probabilities combined with knowledge of failure consequences make it possible to perform a risk analysis. This presentation is based on a public VTT research report 'Risk and lifetime analysis methods for structural systems and components of power plants' the making of which was financed by VTT Industrial Systems
