European networks in relation with the integrity of ageing structures
Three European networks on structural integrity aspects AMES (Ageing Materials Evaluation and Studies), ENIQ (European Network for Inspection Qualification) and NESC (Network for Evaluating Steel Components) are presently managed by the Institute for Advanced Materials as part of the Joint Research Centre of the EC. The networks were launched during 1993. Since then considerable progress has been achieved, which is recorded continuously on Internet. AMES has identified three projects of common interest. The first priority one on the validation of surveillance practice and mitigation methods has been detailed and task groups were set up. The other two projects on irradiation effects on internals and on the significance of Phosphorus causing low toughness in steels are currently in the process of development. ENIQ has moved to a steering committee composed of utilities as voting members. An important step was reached by issuing a consensus document about a European methodology for qualification of non-destructive testing. Main emphasis is put now on a pilot study for the application of the European methodology. The NESC initiative provides a means for EC countries to collaborate in large scale, shared cost experiments that investigate the entire process of structural integrity assessment. The pressurised thermal shock experiment of the first project NESC I is scheduled to take place early 1997 and it makes use of the AEA Technology spinning cylinder facility. Further projects are planned. NESC II involves an extended verification of the structural integrity assessment procedures for CrMoV pressure vessel steels favoured by Eastern countries.
