Trend curve data development and testing
Existing trend curves do not account for previous and more recently observed test and power reactor flux-level, thermal neutron and ..gamma..-ray field-induced effects. Any agreement between measured data and trend curve predictions that does not adequately represent the important neutron environmental and temperature effects as well as the microstructural damage processes, therefore, could be fortuitous. Empirically derived end-of-life (EOL) and life-extension-range (LER) trend curves are presented and discussed in this paper for high temperature (approx.288/sup 0/C (550/sup 0/F)) irradiation of two weld, two plate, and two forging pressure vessel (PV) steels and low-temperature (approx.60/sup 0/C (140/sup 0/F)) irradiation of one support structure-type steel.
