Abstract

The main tasks and problems of VVER reactor pressure vessel (RPV) dosimetry are reviewed taking into account the RPV metal characteristics, the peculiarities of surveillance programs and some features of irradiation embrittlement of VVER-440 and VVER-1000 RPV materials. The problems of dosimetry of VVER-1000 surveillance program are discussed separately. The experimental dosimetry programs, which are carried out in this time, are briefly summarized. It's concluded that there are the serious reasons for improvement of VVER dosimetry.

Keywords:
VVER, reactor pressure vessel, surveillance specimens, dosimetry
