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 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....
