Abstract: The Network for Evaluating Structural Components (NESC) was set up over 10 years ago to address the verification of advanced structural integrity assessment techniques for safety-critical reactor components. Through its self-funded activities and associated projects, partly funded by the European Commission's DG RTD, it has developed a significant body of benchmark R&D data, in particular for large-scale tests performed under closely monitored conditions. Key developments are described in three areas a) fracture assessment for reactor pressure vessels; b) fracture assessment of dissimilar metal welds in primary piping and c) thermal fatigue damage in class 1 and class 2 piping. The added value of combining the efforts of utlities, manufacturers and R&D organisations is stressed.
