Integrity of the VVER reactors internals is the important requirement of the NPPs long term operation. Two possible methods how to meet these requirements are: non destru [...]

The theoretical model is presented. The vibrations are proposed to be random nature and are caused by random pressure fluctuation in the turbulent boundary layer surround [...]

On the basis of electromechanical analogy is as criterion of possible interaction of acoustic waves in primary circuit of NPP Temelin derived so-called quality factor Q. [...]

Licensing of new NPPs is every deterministic. The same is valid for design of all safety related components. Probabilistic methods represent good tool for decision making [...]

An analysis model has been drived on the vibrations of fuel rod induced by coolant cross flow in the reactor core. The force on the fuel rod was fitted out using paramete [...]

Specific feature of the nuclear power plants is in comparison with coal fired plants the break postulation of each high energy piping. Fluid system is considered as high- [...]
