Along with the second refuelling after 47700 h of operation were carried out on the reactor pressure vessel of NS OTTO HAHN large-scale inservice inspections. The results and further investigations have shown, that the safety of the reactor pressure vessel will be guaranteed. The ultrasonic testings were performed without any manipulating system. The reproducibility of indications is ensured by measurements taken in relation to reference points in the various a test areas. An intensive dismantling effort was required on the compact design of the nuclear vessel plant down to the various test areas on the reactor pressure vessel. (Se)
