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.
