The paper follows up on last year's presentation of the new ŠKODA JS a.s. equipment, which is designed to carry out operational inspections of irradiated fuel assemblies at the Temelín NPP in the Czech Republic. The paper presents practical experience with the preparatio...

During the periodic inspection, four linear indications were found on the surface of the turbogenerator rotor blade in the region of the leading edge using the magnetic powder NDT method. Based on these results, a transfer of the blade to the accredited laboratories of ÚJV�...

In recent years, ŠKODA JS a.s. has been trying to keep up with current industry trends and has started to focus intensively on virtual reality, augmented reality (VR, AR) and 3D printing. The first efforts to use these technologies began already in 2012, when the&#...

Due to the adoption of the so-called Paris Agreement on climate change, the Czech Republic has committed to reducing greenhouse gas emissions (mainly carbon dioxide) by 55 % until 2030 compared to 1990. One of the options for reducing emissions in the transport sector&#...

Cold Spray (CS) is state-of-the-art technology in the family of thermal spraying. The prin- ciple of this technology is to accelerate microscopic particles to a very high speed and deposit them on a substrate where the kinetics energy is converted into deformation and t...

The service life of industrial units is a crucial parameter in operation as well as in their design phase. A digital twin combines both. Design models based on the common standard of FEM simulations do not have to end in the production of a power block as...

The high-voltage synchronous machines are very often used as generators for the production of electric power not only in nuclear power plants but also in conventional thermal, wind, and hydropower plants. Regular diagnostic equipment checks also include visual inspections to ensure reliable&...

Thermography is a modern diagnostics method with a significant potential for utilization in diagnostics, maintenance, monitoring, or non-destructive testing of power industry devices. The main advantages of thermography belong its non-contact and non-destructive basis, the possibility of area&...

Techniky reverzného inžinieringu zahŕňajú analýzu existujúceho dielu, ako aj zhodnotenie dostupných informácií o jeho konštrukcii a funkcii, aby sa umožnila jeho výroba respektíve oprava. Reverzný inžiniering sa zvyčajne používa v situáciách, keď nie sú k dispozícii úplné informácie o pôvodnom di...

In this paper, several different nickel-based coatings were tested under laboratory conditions in a model atmosphere simulating biomass flue gas containing chlorine and other elements and under a model deposit. In addition to different types of nickel coatings, different deposition technologies&#...

The service life of the lower parts of the membrane walls is influenced by the operating parameters and design of the boilers, but above all, by the fuel used. During the combustion of wood chips, straw, corn, and solid alternative fuels, created during the recycli...
