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.

Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.

Design and Analysis of Systems for Advanced Guarding and Securing Objects and Areas
Komínek, Petr ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.

Finalisation of development and verification of Flow123d software within the DECOVALEX 2015 project
Blaheta, Radim ; Maryška, J. ; Březina, J. ; Stebel, J. ; Šembera, J. ; Balvín, A. ; Bruský, I. ; Hasal, Martin ; Michalec, Zdeněk ; Staš, Lubomír ; Sysala, Stanislav
This final report summarizes the progress of work and results for the whole period of the project. The subject is modelling of tasks within the project Decovalex-2015, development of Flow123d software, and preparation of documents for its standardization using the comparison results with foreign teams. TUL team participated in Task C1 (THMC processes in a single fracture) using the software Geochemist’s Workbench and their own tool TrAper for connecting chemistry and deformation and Task C2 (flow and transport in the vicinity of the tunnel Bedřichov) using Flow123d software. Task C2 also includes the formulation of the assignment and coordination of the solution of other teams. The ÚGN team participated in Task A, focusing on saturation of bentonite seals in clay rock and closing the gap, with the help of the COMSOL Multiphysics software. The outputs are the joint report by international teams and papers in a special issue of a journal. The developed models and lessons learned contribute to the ability to predict phenomena in the deep geological repository. Another result is a set of documents for the Flow123d software. All of which are attached to the report as attachments.
