Review of the literature related to modelling the interaction of copper and ultrasound

摘要

The Swedish program for disposal of spent fuels will be faced with the problem of approving an ultrasonic testing scheme for large copper vessels to be used for the disposal. The microstructure of the vessels is uncertain. Manufacturing technology for such vessels is not yet established, but those under consideration could lead to a number of defects which may be critical to the performance of the canister. One method for detection of such defects is ultrasonic inspection. The reliability of this method is limited by the signal to noise ratio that may be achieved. The present literature review shows that there is excellent potential to make progress in the ultrasonic inspection by using one model as a theoretical predictor, the Rose model, and a further model model as an experimental validation, the ISMBB. Recommendations are made for the next stage of this project. 32 refs. (Atomindex citation 27:029185)
