Analysis of embrittlement of WWER-1000 RPV materials
International Journal of Pressure Vessels and Piping, 2012Abstract Analysis of embrittlement for WWER-1000 RPV materials is performed on the basis of available and original experimental data. Contributions of thermal aging and neutron irradiation to embrittlement are considered for base and weld metals. Equations have been obtained for the shift of the critical temperature of brittleness as a function of ...

WWER RPV embrittlement: start of life toughness
International Journal of Nuclear Knowledge Management, 2011It is well known that neutron irradiation affects the properties of reactor pressure vessel material. The methodologies to assess the embrittlement of LWR (PWR, BWR and WWER types) are all based on the shift induced by irradiation of a reference transition temperature.

WWER RPV Surveillance Programs
2018Water-water energetic reactors (WWERs) are, in principle, pressurized water reactors but designed and manufactured from Russian-type materials and operated according to former Soviet/Russian rules, standards, and requirements. Their surveillance specimen programs are designed, manufactured, operated, tested, and evaluated with the same purpose but with

Evaluation of WWER-440 Surveillance at Paks NPS
1989The surveillance program of the WWER-440 type pressurized water reactors (PWRs) is somewhat different from the surveillance programs of other PWRs. In view of this, a surveillance evaluation system was developed to solve the open questions connected with the design. This system was used to evaluate the results of the first two units of Paks NPS.

A historical review of WWER RPV embrittlement issues
International Journal of Nuclear Knowledge Management, 2011The paper tries to describe the history of the radiation effects study in WWER type reactor pressure vessels – from their design, manufacturing and operation point of view. The paper shows the time evolution and also institutions that were and are included in this research and development study.
