Accelerated capsules (LF≈11.7) have been built in the reactors of the Hungarian NPP Paks, for RPV surveillance investigations. As these capsules have been used up in a few years, a new RPV surveillance program has been developed and was put into operation in 1991. The aim of the new program was partly to improve the results of the former one, and hereby to decrease the uncertainty in the RPV service life assessment, partly to introduce “cavity” dosimetry and to monitor the irradiation of the RPV during the remaining service life of the NPP. This paper gives an overview on the reactor dosimetry results obtained with the original RPV capsules — built in by the supplier of the NPP — and, presents the first results of the new program. Conclusions related to the service life of the RPVs are drawn.
