Analysis of eddy-current testing and metallographic examinations for corrosion damages of heat exchanging tubes in NPP steam generators

Analysis of Efficiency of Technical Condition of Heat Exchanger of Spent Fuel Pool Cooling System with WWER-1000 Reactor of Nuclear Power Plant

“… ensuring the concentration of boric acid of at least 16 g/dm 3 both during refuelling and storage of spent fuel.…”

“…In the process of operation, the elements of the heat exchanger of the SFP cooling system are gradually exposed to external and internal factors. This can lead to the loss of tightness and destruction of the tube elements of the heat exchanger, and ultimately to failure [3]. The scientists and specialists in this field of research have found that extending the service life of the facilities through partial replacement and repair of equipment becomes an economically and technically feasible way to increase industrial potential.…”

Theoretical Aspects of Modern Engineering

“…Measuring the magnetic susceptibility of ferrite powders allows you to quickly test the size of magnetic nanoparticles.Nanotechnology makes it possible to obtain ferrites in non-equilibrium conditions.Studies have shown the features of the electron-ion structure of ferrites in nonequilibrium states. ТОТ, так і на поверхні відкладень, а також і в самих відкладеннях[219]. На місце води, що випарувалася, з ядра потоку до поверхні ТОТ надходять нові порції води, а разом з нею і розчинені в ній домішки.…”
