Experimental investigations of the effect of new passive safety systems on the temperature state of fuel elements

Results of experiments conducted on a large-scale integral PSB-VVéR bench and directed toward investigation of the performance of new passive safety systems for nuclear plants with a water-cooled power reactor, an additional system for passive flooding of the active zone, and a system for the passive removal of heat from steam generators are presented. __________ Translated from élektricheskie Stantsii, No. 9, September 2007, pp. 7–10.     

Special features of transformation kinetics of austenite in heat treatment of stamped and welded components made of 10G2FBYu steel

The results of investigations of the special features of austenite transformation kinetics during heat treatment of welded joints in components made of 10G2FBYu steel are used to determine the conditions for producing stamped and welded connecting components with strengths similar to that of the parent metal.     

Physicochemical aspects of petroleum coke formation (review)

The current status and development of petroleum residue upgrading via coking in Russia and over the world have been surveyed with an emphasis on the role of the process in salving the problem of increasing the refining depth. Theoretical concepts of thermal conversion of heavy petroleum feedstock and the structure of asphaltenes as principal coke-forming compounds have been discussed, the results of studies on the formation of coke as either a byproduct or (to a greater extent) the desired product have been considered, and models of the coke structure have been proposed. The characteristic features of the coking process for petroleum residues of various chemical compositions have been addressed, as well as means for controlling the feedstock thermal stability and the yield and quality of coke with the use of external factors.     

Surface ionization properties of alkali metal oxide bronze

The process of selective ionization of a nitro compound (trinitrotoluene) on the surface of poly- and single-crystalline samples of sodium-vanadium oxide bronze has been studied in air at atmospheric pressure.     

Experimental–theoretical study of high-cycle failure of structural elements of VZh-159 alloy

The results of an experimental–theoretical investigation of high-cycle fatigue of a VZh-159 alloy at a temperature of 850°C are represented. A model and algorithm for the prediction of fatigue damages are proposed, which, with respect to relationships of damaged-medium mechanics, permit the simulation of processes of high-cycle structural failure subject to general factors affecting the cyclic strength of structural material. The results of the numerical simulation of high-cycle failure of structural elements are given that verify the working capacity of the proposed model, algorithms, and software environment developed based on it.
