摘要：
Surveillance schemes that monitor the effect of neutron irradiation on reactor pressure vessel materials employ Charpy impact specimens that are periodically withdrawn and tested over a range of temperatures. The resulting Charpy impact absorbed energy curves have been modelled by a three parameter relationship with the same functional form as the Burr distribution function. A method is presented for the evaluation of Charpy curves based on Bayesian inference and employing Markov chain Monte Carlo simulation to quantify the model parameters and the uncertainties.
