Facelift PDU
Růžičková, Tereza ; Kyselka,, Mojmír (referee) ; Nový, Alois (advisor)
The theme of the diploma thesis is the solution of the pre-plant zone of the Dukovany nuclear power station. Creating a vision of how this space could develop further in the next 50 years and how it could work in a transitional phase during the construction of a new nuclear power plant unit. The subject of the thesis is the elaboration of an architectural study, which is based on an urban study. Urban study was processed within the framework of the pre-diploma thesis and solved mainly the overall problems of this area, the new transport connection, and the functional division of the whole area. The area was divided into three functional units, namely the transport zone, the administrative zone and the sports and education zone. At present, there are a lot of small structurally and functionally unsuitable buildings in this area. The diploma thesis deals with the design of new buildings with a clear functional use in the administrative zone, in the area in front of the main gatehouse. A new representative square was created, and three buildings are designed around it. The dominant feature of the whole area was a high-rise office building near the gatehouse. In front of the office building, towards the main road, the service building I was designed, which contains business and healthcare services. On the other side of the square was located the service building II, where there are technical services, such as workshops, warehouses and metrology. The last building solved within the diploma thesis is the building of sports and locker rooms of suppliers, which is designed behind the square near the greenery. New building copies mass of the only preserved building in this area, namely the building of the information centre. The designed building has a fitness centre and locker rooms of external workers of the power plant.

Parking house of NPP Dukovany
Marečková, Andrea ; Rosendorf, Aleš (referee) ; Boleslavská, Yvona (advisor) ; Matějka, Libor (advisor)
The subject of the bachelor thesis is to solve the crisis situation of parking at the Dukovany Nuclear Power Plant. Parking areas in front of the company are still the same, but the number of cars is growing rapidly. Therefore, the power plant management decided to solve this situation. Two nearly identical parkades were designed for this area to cover the capacity of 1572 parking spaces. It is a simple design of a 5-storey prefabricated building made of reinforced concrete columns, beams, SPIROLL panels and other elements. For better bracing of the building, the vertical communication cores were designed as monolithic reinforced. The façade of the building consists of a suspended structure fitted with expanded metal, which will help with incoming light and also with the exchange of degraded air in the garages. On the first floor there is a parking space for 142 cars, of which 4 are parking stalls for charging electric cars and 10 stalls for designated handicap parking, all these stalls are located only on the ground floor for easier access of the car owners. In addition to these parking stalls, there are three vertical communication cores with staircases and elevators. At one communication core is also a sanitary facility with toilets for men, women, for people with disabilities and cleaning room. Two ramps are designed for vertical crossing of cars in the middle of the ground plan. Self-service washing boxes and utility room were designed according to requirements. The second and subsequent floors are identical. There are 161 parking stalls on each floor, 4 of them are for charging electric vehicles. There are also sanitary facilities and a utility room. For the safety of pedestrians, the entire parkade is marked with horizontal roads, thanks to which the employees get from their cars to the communication core and out of the building.

Parking house of NPP Dukovany
Machů, Jana ; Vlachynský, Ladislav (referee) ; Boleslavská, Yvona (advisor) ; Matějka, Libor (advisor)
The theme of this bachelor thesis is the design of the building of the Parking house for the Dukovany nuclear power plant. The basis of this work is based on the subject AG035 – Architectural design studio 5. The area is flat and large enough, so there was a requirement to repeat the building on this land in the second stage of construction. Therefore, two mirror-identical objects (SO01 and SO02) are designed in one area. In this bachelor work is solved object SO01. The land is trapezoidal, half of which now has a parking area. Along the northwest boundary of the plot lies a road to which the plot connects in the northern part. Now the land is located on the northwest side of the nuclear power plant, however, the construction of another part of the power plant is planned and thus the parking house will occur in the middle of these two units. The parking house is designed as a four-storey building with 787 parking spaces. It is a simple mass in the shape of a block, which is accentuated by a protruding cantilevered staircase on each side of the building. The building also visually plays on the facade with its closed and open areas, which are covered by aluminum slats. Structurally the building is designed as reinforced concrete, for the most part prefabricated (columns, girders and ceiling panels) for speed and simplicity of construction, but there is also used monolithic reinforced concrete (walls and ceiling slabs) to reinforce the building. The construction system is bidirectional.

Risks Related to Involving the Voluntary Fire-fighter Units in the Radiation Situation Monitoring
Myslíková, Veronika ; Strmeň, Milan (referee) ; Adamec, Vladimír (advisor)
This diploma thesis focuses on the analyzing the current state of monitoring the radiation situation by volunteer firefighters units in the emergency planning area in Dukovany nuclear power plant surroundings. The process of measurement is divided into preparation for radiation leakage and application of learned procedures in the case of the occurred radiation leakage. The aim is to identify the dangers in the current process as well as the possible risks in the case of radiation emergency by risk analysis. Based on this analysis, improvements suggestions will be made. These measures will be evaluated by their applicability and their economic value. The system of monitoring by voluntary firefighters will be compared with another monitoring system, which can be also used. The result of the analysis will be a more effective way of monitoring, including safety of the firefighter and less financial complexity.
