Small modular reactors
Mareček, David ; Šnajdárek, Ladislav (referee) ; Kracík, Petr (advisor)
This bachelor's thesis explores a new and promising type of nuclear reactor: small modular reactors (SMRs). It begins with a brief introduction to the basics of nuclear energy, nuclear physics, and their historical development. The fundamental concepts related to SMRs, as well as the definition of SMRs themselves, are explained. The thesis then outlines the various prop-erties and advantages of SMRs. It includes a description and comparison of 9 different types of SMRs, followed by a detailed analysis of the 10 most advanced SMR projects. Additional-ly, it provides an overview of the legislative requirements for implementing SMRs in the Czech Republic. Finally, the thesis discusses the reasons for integrating SMRs into low-carbon energy and explores their potential applications.

Šimůnková, Radana ; Brně, Kamil Števanka, OR NJZ MPO a FEKT VUT v (referee) ; Katovský, Karel (advisor)
The future development of the energy sector is linked to the 3 D - digitalisation, decarbonisation and decentralisation. This group could be expanded to include a fourth D - diversification of resources. Since the second half of the 1980s, the use of nuclear energy has been an integral part of the Czech energy sector. With the development of nuclear energy, small modular reactors are often mentioned today. The construction of small modular reactors could help transform the energy mix, which needs to be adapted to the imminent end of coal use for energy purposes. This thesis contains a detailed description of potential sites for the future location of small modular reactors in the Czech Republic and analyses the individual sites using the author's methodology. An overview map with potential sites was created in QGIS software. Furthermore, the thesis summarises and describes the most promising small modular reactor projects and evaluates them according to the methodology recommended by the International Atomic Energy Agency. Finally, the thesis proposes the consideration of additional sites with regard to the potential use of waste heat.
Simulational model of utilization of process heat in the system with advanced small modular reactors
Doležal, Václav ; SÚJB, Jan Varmuža, (referee) ; Katovský, Karel (advisor)
This thesis explores the history and current utilization of heat from nuclear power plants, particularly small modular reactors (SMRs). The work initially analyzes the historical development and surveys past projects in this area. Furthermore, it provides an overview of possible applications of heat from nuclear power plants. Subsequently, the thesis focuses on advanced projects of small modular reactors with an emphasis on the industrial use of heat. In the practical part, a system model is constructed that integrates process heat from SMRs in systems of selected potential consumers with the possibility of concurrent hydrogen production.

Subject of this thesis is design of the steam generator for modular reactor. The dissertation consist of the theoretical part, where are described heat-exchangers and steam generators used in nuclear power plants. Second part contains theoretical calculations in the first approach (thermal, hydraulic and strenght calculation). In the next part are particular variants of steam generator selected. For the final variant are necessary calculations (introduced above) and drawings of selected parts are done. In the final statement is technical solution evaluated, and the parameters of the steam generator are compared with actually used steam generators.

Tato diplomová práce představuje koncept elektrického invalidního vozíku ovládaného lidskou myslí. Tento koncept je určen pro osoby, které elektrický invalidní vozík nemohou ovládat klasickými způsoby, jakým je například joystick. V práci jsou popsány čtyři hlavní komponenty konceptu: elektroencefalograf, brain-computer interface (rozhraní mozek-počítač), systém sdílené kontroly a samotný elektrický invalidní vozík. V textu je představena použitá metodologie a výsledky provedených experimentů. V závěru jsou nastíněna doporučení pro budoucí vývoj.
Overview and Utilization of Small Modular Reactors
Křeček, Tomáš ; Števanka, Kamil (referee) ; Katovský, Karel (advisor)
This bachelor thesis deals with an auspicious type of new nuclear reactors – small modular reactors (SMR). It defines the basic qualities of SMR and their essential differences among large nuclear reactors, briefly evaluates the individual advantages and disadvantages. It summarizes the history and current direction of their development in the most active countries. In the bachelor's thesis are also discusses the most advanced propositions of SMR and the possibilities of their use. In the last part is analysis of the usability of SMR in the energy mixture and the possibilities of application in the Czechia.

Immediate effect of posterior chain facilitation using foam rolling on reactive strength performance
Harasimová, Petra ; Hojka, Vladimír (advisor) ; Šťastný, Petr (referee)
Author: Bc. Petra Harasimová Thesis supervisor: Mgr. Vladimír Hojka, Ph.D. Expert consultant: PhDr. Jitka Malá, Ph.D. Mgr. Dominik Kolinger Title: Immediate effect of posterior chain facilitation using foam rolling on reactive strength performance. Objectives: The main aim of this study is to determine whether the inclination of the trunk towards the vertical changes after foam roller facilitation, whether the magnitude of the jump increases or whether the contact time during reactive force performance is reduced. Methods: In this thesis an experiment in the form of a randomized crossover study was used. Fifteen active female athletes with the problem of physiological maintenance of trunk position during running participated in the measurement. Subjects performed repeated snatch jumps over hurdles 57-68 cm in height. For the skip jumps, we measured jump height and support time using an Optojump (Microgate, Bolzano, Italy) and maximal trunk tilt using a video camera (GoPro HERO 9). After the warm-up, probands completed two measurements (pre-test) within 2 minutes. Then, the intervention group of probands performed foam rolling facilitation - m. triceps surae, mm. hamstrings, m. gluteus maximus, m. erector trunci; for each muscle group for 30 s, with a frequency of 1.5 Hz; the control group had rest...

Polák, Zdeněk ; Král, Jan (advisor) ; Havelka, Jaroslav (referee)
Tato diplomová práce se zabývá zhodnocením inženýrskogeologických poměrů mostu na stavbě č. 519 silničního okruhu kolem Prahy včetně vyšetření stability skalních svahů v místě předpokládané výstavby. Jedná se o přemostění hlubokého erozního údolí Vltavy, na jehož svazích vystupují na povrch horniny svrchnoproterozoického stáří. Na lokalitě byly zhodnoceny pomocí rešerše archivních podkladů, vlastní rekognoskace a laboratorních zkoušek, geologické, hydrogeologické a inženýrskogeologické poměry, které jsou přehledně uvedeny v inženýrskogeologické mapě v měřítku 1:2000 a řezu 1:500. Jako podklad pro vyhodnocení stability skalních svahů sloužila podrobná dokumentace skalních výchozů. Samotné vyšetření stability proběhlo pomocí klasifikace Slope Mass Ratting a Marklandova testu pro stereografickou projekci. Na výstupech práce je souhrnně popsán horninový masiv včetně mapy stability skalních svahů v měřítku 1:500 a popsány základové poměry uvažovaného mostu.
