The technical publication contains the latest NDT qualification achievements in the following inspection areas of WWER type RPVs and piping systems: 1. TOFD examination of WWER 440 and WWER 1000 type RPV butt welds, 2. Pulse-echo examinations of longitudinal austenitic welds of elbows and 3. Phased array examinations of circumferential welds and longitudinal elbow welds of different piping systems. The progress in the TOFD RPV application is especially in high level involvement of computer modelling simulation by CIVA s/w (CEA, France). The level of compliance of TOFD examination and TOFD simulation results was confirmed for many defects in the 1:1 large scale test assemblies [1]. The progress and lessons learnt from pulse-echo examinations of longitudinal austenitic welds of elbows is related to Leak Before Break Concept Application for Primary piping and Pressurizer surge line piping at ANPP in Metsamor (Armenia) where there were increased requirements on in-service inspection including NDT qualification of pressurizer surge line longitudinal welds on elbows and primary piping longitudinal welds on elbows under the Main Circulation Pump. The progress in phased array applications on circumferential welds and longitudinal elbow welds of different piping systems is also accompanied by extended computer modelling simulation by CIVA s/w. Several examples of compliance of phased array (PA) examination and PA simulation results are given for many defects in the 1:1 piping weld test assemblies [2]. The paper contains also briefly the scope of the training of Armenian UT inspectors at NRI based on the contract sponsored by IAEA Vienna. Lessons learnt obtained within the UT training of Armenian inspectors coming from NDT qualification training, open and blind trials on available test assemblies are shortly presented, as well.
