ASSESSING THE DEFECT-FREE STRUCTURE

There has been a strong incentive within Nuclear Electric to develop a comprehensive assessment procedure to evaluate the high temperature r esponse of structures; the so-called R5 procedure is extensive and Vol s. 2 and 3 deal with the analytical approach and the assessment of cre ep fatigue damage for defect-free structures. In this paper we describ e the approach which has been adopted and identify the relationship be tween the analytical requirement and material damage assessment under cyclic loading.
