Journal ArticleDOI
Thermal ageing mechanisms of VVER-1000 reactor pressure vessel steels
TL;DR: In this paper, a complex of microstructural studies (TEM and SEM) and a comparative analysis of the results of these studies with the data of mechanical tests of temperature sets of VVER-1000 RPV surveillance specimens with exposure times up to ∼200,000h were conducted.
Journal ArticleDOI

TL;DR: The use of the commonly used maximum separation distance and local concentration thresholding methods for solute clustering quantification is investigated to bring clarity to the range of applicability; identify existing and/or needed modifications; and interpretation of past published data.
Journal ArticleDOI
Influence of structural parameters on the tendency of VVER-1000 reactor pressure vessel steel to temper embrittlement
B. A. Gurovich,Evgenia Kuleshova,O. O. Zabusov,S.V. Fedotova,A.S. Frolov,M.A. Saltykov,D.A. Maltsev +6 more
TL;DR: In this paper, the influence of structural parameters on the tendency of steels to reversible temper embrittlement was studied for assessment of performance properties of reactor pressure vessel steels with extended service life.
Journal ArticleDOI
Evolution of weld metals nanostructure and properties under irradiation and recovery annealing of VVER-type reactors
B. A. Gurovich,Evgenia Kuleshova,Ya. I. Shtrombakh,S.V. Fedotova,O. O. Zabusov,K. E. Prikhod’ko,D. A. Zhurko +6 more
TL;DR: In this paper, the results of VVER-440 steel Sv-10KhMFT and SV-1000 steel SV-10khGNMAA investigations by transmission electron microscopy, scanning electron microscopes, Auger-electron spectroscopy and mechanical tests are presented.
Journal ArticleDOI
Assessment of segregation kinetics in water-moderated reactors pressure vessel steels under long-term operation
Evgenia Kuleshova,Evgenia Kuleshova,B. A. Gurovich,Z. V. Lavrukhina,M.A. Saltykov,S.V. Fedotova,A. N. Khodan +6 more
TL;DR: In this article, the Auger electron spectroscopy (AES) was used to study the grain boundary (GB) composition of VVER-1000 RPV steels with different thermal exposure time at the RPV operating temperature as well as irradiated by fast neutrons.
