On the history and status of reactor pressure vessel steel ductile to brittle transition temperature shift prediction models
TL;DR: In this article, the authors present an overview of the history of Reactor Pressure Vessel (RPV) embrittlement research, focusing on predicting ductile-to-brittle transition temperature shifts (ΔT), along with an assessment of the current status of these efforts, especially for extended life operation.

Effects of neutron flux on irradiation-induced hardening and defects in RPV steels studied by positron annihilation spectroscopy
TL;DR: In this paper, the authors studied the effects of neutron-flux effects on irradiation-induced hardening and microstructures in a reactor pressure vessel steel and showed that defects in which positrons are trapped are the origin of irradiation hardening.

Advanced method for WWER RPV embrittlement assessment
TL;DR: In this paper, a semi-mechanistic model is proposed to predict embrittlement and re-embrittlement after annealing of high P materials typical of certain VVER-440 RPVs.
Journal ArticleDOI
Evaluation of irradiation damage effect by applying electric properties based techniques
TL;DR: In this paper, the authors compared the results of the impact tests, STEAM and REAM measurements with the change in the mechanical properties due to neutron irradiation in order to assess non-destructively the embrittlement state of materials.
