Abstract

Two non-destructive methods were applied to examine the quality of experimental test welds of disposal canisters. Altogether four welds were scanned and data acquired with ultrasonic and radiographic methods. The ultrasonic method utilised a 128 elements linear phased array probe that was applied with 0° and ± 20° beam angles. The radiographic method applied a 9MeV linear accelerator and a digital detector with pixel size of 0.4 x 0.4 mm. The data was analysed applying the standard procedure developed for the inspection of the canister closure welds. All detected defect indications were analysed and sized. The results are presented in the tables and figures of this report. A considerable amount of figures are produced and attached in the appendixes to show the overall quality of the welds and the excact placement of the detected defects. According to performed ultrasonic and radiographic inspection the welds XK049 and XK050 were nearly flawless. The welds XK054 and XK055 inluded a large number of defects that were clearly revealed by the applied inspection techniques.
