Abstract
Two USSR-produced forging steels representing the Cr-Mo-V forgings employed in the construction of USSR light-water VVER-440 reactor pressure vessels before and after 1980, respectively were investigated for irradiation effects on their Charpy V-notch ductilities. The materials differ primarily with their P content. The observed Charpy V-notch 41 J transition temperature elevation values are considerably less than the elevations predicted by NRC Regulatory Guide 1.99, Rev. 2. On the other hand, upper-shelf energy level reductions found for the pre-1980 material was higher.
