Currently it is acknowledged that the problem of disposal radioactive waste (RW) from nu-clear reactors largely depends on use fast neutron (fast reactors) in nuclear power industry. These are able to burn and transmutate long-lived radionuclides closed fuel cycle (NFC). In an open NFC with thermal (thermal reactors), unpro-cessed spent (SNF) buried. a reprocessed SNF disposed. this paper, feas...

By using the developed finite-element models, we perform numerical investigation of nonstationary temperature fields and kinetics microstructural phase transformations in base material WWER -1000 reactor vessel (15Kh2NMFА steel) under conditions submerged-arc cladding protective anticorrosion layers austenitic materials. We comparative analysis results simulation obtained by two methods predict...

The relevance of this work is determined by the need to predict operation sealing joints transport locks WWER-1000 and WWER-1200 power units in operational modes. results tests rubber seals for tightness are given. Based on study, used was assessed recommendations developed increase reliability

The appearance of free, weakly fixed and foreign objects in the main circulation circuit is not ruled out reactor plants with a pressurized water power reactor. These objects, moving coolant flow, can collide inner walls circuit, which lead to equipment damage. Early detection these will minimize damage improve safety NPP operation. plant equipped system for detecting loose/weakly this purpose....
