A crucial issue in the view of changing boundary conditions is the prevention of fatigue damages: code modifications, lifetime extension and new plants with operating periods of 60 years. ‘The AREVA fatigue concept (AFC) provides for a multiple step and multidisciplinary process (process engineering, fatigue monitoring, fatigue analyses, etc.)against fatigue before and during the entire operation of nuclear power plants’ (Rudolph 2009). Within this integral concept AREVA’s fatigue monitoring system FAMOS serves as the basis. With the help of FAMOS the real local operating loads are measured at the fatigue relevant locations of the primary and secondary circuit pressure boundary components.

FAMOS for CANDU and its accompanying fatigue assessment methods: great value to availability, optimisation and long term operation LTO.
