Design of equipment of spent nuclear fuel assemblies
Šimek, Ondřej ; Rausch, Ivan (referee) ; Vojáčková, Jitka (advisor)
The diploma thesis aim to the design of equipment for ŠKODA JS a.s., which is part of a new inspection stand (N-SIO). This equipment is an inspection column that provides the possibility to inspect spent fuel assemblies at the operation of the Temelín nuclear power plant. This master thesis is also a summary of the whole design of the new inspection stand and a description of the individual inspection components and devices. One of the parts of the thesis is also a basic strength analysis and a drawing of the main assembly of inspection equipment.

Design of the uderground part of the building
Šimek, Ondřej ; Hrubý, Tomáš (referee) ; Klusáček, Ladislav (advisor)
The bachelor‘s thesis deals with the design and assessment of reinforced concrete monolithic supporting structure of underground garages under apartment building at ultimate limit state and also at serviceability limit state, according to ČSN EN 1992-1-1: Design of concrete structures. Specifically, the design of the ceiling slab, girders, the selected column, the selected part of the wall and foundation under columns. Other parts of the building are not solved in the project. The text part contains general information on the desing of the structure, static idealization of the structure, type of load and method for calculation of inner forces. Attachments contain structural analysis, which completes the text part and solves in detail selected elements of the structure and the drawing documentation.

Processing of a Digital Picture in the Lesson Plan
Šimek, Ondřej ; Lustig, Stanislav (advisor) ; Jiroušková, Ivana (referee)
Tato diplomová práce pojednává o problematice digitálního obrazu. V teoretické části je nejprve specifikován pojem digitální obraz. Dále se práce zabývá digitálním obrazem, jako didaktickou pomůckou a jeho možností při uplatnění ve vzdělávacím procesu. Následující kapitoly jsou zaměřeny na problematiku digitálního obrazu z technického pohledu od principů záznamu až po samotnou prezentaci. Příloha obsahuje ukázky, které nastiňují praktické možnosti využití digitálního obrazu. Součástí práce jsou i elektronické podklady doplňující technicky zaměřenu část. Dohromady s technicky zaměřenou částí by měly tvořit podklad pro výuku. Powered by TCPDF (www.tcpdf.org)

Benchmarks and test facilities of VVER reactors
Šimek, Ondřej ; Foral, Štěpán (referee) ; Vojáčková, Jitka (advisor)
The aim of this bachelor’s thesis is to describe the topic of benchmarks and test facilities for pressurized water reactors of the eastern concept VVER type. The theoretical part introduces the VVER type reactors, their history, the development of separate generations, including fundamental differences and parameters of the VVER type reactors being used so far. Next two chapters of the theoretical part focus on nuclear safety and security, describing the uppermost Czech authorities, which are SÚJB, MAAE and NEA. Furthermore, many terms concerning nuclear safety are explained in these two chapters. The next chapter is focused on deterministic safety analyzes, their classification, methods and purposes. The aim of this part is also to explain the verification and validation of computing codes. The next chapter offers insight into test facilities which are crucial for evaluation and testing of nuclear devices and computing codes. The last chapter of the theoretical part focuses on the VVER type reactor benchmarks. The practical part of this thesis presents the conversion of a single AER Benchmark FCM_001 using neutron physical code PARCS. The results are compared to the results of CRONOS computing code.

Production process monitoring system
Šimek, Ondřej ; Musil, Martin (referee) ; Fiala, Alois (advisor)
This thesis deals with production system monitoring using the SPC method. The reason for the introduction of the SPC system is in an effort to improve the quality consistantcy.This master thesis consists of three parts: Teoretic part: to solve the basic access and process for the aplication of SPC methodics. Practical part: includes the descripton of comtemporary quality control and propositions for the SPC method. Conclution:Conclusions and recommendations are made on the basis of the data evaluation.

Modelování kapalinově scintilačních spekter metodou Monte Carlo
Šimek, Ondřej ; Šídlová, V. ; Světlík, Ivo ; Tomášková, Lenka
The paper is aimed on simulations of liquid scintillation (LS) pulse spectra of beta emitters without additional interfering effects. The explanation of the non-influenced shape of liquid scintillation pulse spectrum gives a better possibility to indicate additional interferences as: presence of other radionuclides, unstability of the scintillation mixture, various types of wall effects, color quenching, etc. We concentrated on the scale of energies above 100 keV, hence a great number of additional effects, with a small quantification possibility, can be expected in the parts below. Results of simulations of energy deposition from primary electrons, leakage of the electrons from counting vial, and fluctuation of the energy transferred by scintillation chain are described and briefly discussed.
