Biemiller, E C

The curves used by C-E for System 80 reactor vessels to predict the change in reference temperature (RT/sub NDT/) as a function of fluence and residual element content are presented. Five curves are necessary to accurately and conservatively predict the changes in RT/sub NDT/ of the materials used in the fabrication of a vessel. A correlation between Charpy impact upper shelf energy reduction, irradiation fluence, and residual copper content is also presented. Percent shelf reduction data are plotted versus the square root of fluence, and trends are established based on copper content. The curves presented are based on irradiation data for A533-B, Class 1 materials. They are drawn conservatively to envelop the data, yet follow actual trends described by the data. C-E will use these curves for the prediction of RT/sub NDT/ shift and Charpy upper shelf energy reductions with irradiation for System 80 reactor vessel materials.
