Non-stacionary thermal field in the nozzle at stream mixing
Vosynková, Jana ; Vincour, Dušan (referee) ; Nekvasil, Richard (advisor)
Nuclear energy is already well known area of energy generation. However, it is necessary to eliminate the potential risks of failure. That places special emphasis on safety in production and operation of nuclear power, especially its primary circuit. This work is focused on thermal damage to the injection nozzle, which is part of the pressurizer in the primary circuit Dukovany plant.The aim was a comparative analysis of two geometries nozzle which were loaded by varying temperature loading trought time and by static preassure loading. Main attention was placed on the thermal shocks in the material.

Design of vertical heat exchanger
Vosynková, Jana ; Buzík, Jiří (referee) ; Nováček, Filip (advisor)
Diploma thesis describes the design of a vertical heat exchanger in accordance with European standard ČSN EN 13 445-3 Unfired pressure vessels - Part 3: Design (in Czech). The first part contains the distribution of heat exchangers including an overview of the most commonly used media. The main part is aimed on the strength assessment of the heat exchanger based on the mentioned standard. The assessment equations are converted into an interactive document in Mathcad program. This allows quick evaluation of the new input parameters or easy implementation of the new parts of assessment. Checking the analytical evaluation is performed by numerical simulation in Ansys Workbench software with post-processing results according to given standard (stress categorization). The output is also the heat exchanger design documentation.
