Simulation of Accelerator Driven Nuclear Reactor for Spent Nuclear Fuel Transmutation
Jarchovský, Petr ; Ing. Antonín Krása, Ph.D., SCK.CEN Mol (referee) ; Katovský, Karel (advisor)
This master’s thesis deals with usage of burn-up (spent) nuclear fuel in nuclear power plants of next generation – accelerator driven transmutation plants which is produced in current nuclear power plants. This system could significantly reduce the volume of dangerous long-lived radioisotopes and moreover they would be able to take advantage of its great energy potential due to fast neutron spectrum. In the introduction are listed basic knowledge and aspects of spent nuclear fuel along with its reprocessing and the possibility of further use while minimizing environmental impact. As another point detailed description of accelerator driven systems is described together with its basic components. In addition this search is followed by individual chronological enumeration of projects of global significance concerning their current development. Emphasis is placed on SAD and MYRRHA projects, which are used like base for calculations. This last, computational part, deals with the creation of the geometry of subcritical transmutation reactor driven by accelerator and subsequent evaluation which assembly is the most effective for transmutation and energy purposes along with changing of target, nuclear fuel and coolant/moderator.

ZOO BUILDINGS – HERALDIC ZOO
Valchová, Jana ; Pospíšil, Zdeněk (referee) ; Boháč, Ivo (advisor)
The main idea of project is to design heraldic zoo in the area of old castle park Horní Hrad, which is located few kilometers next to the Karlovy Vary. Heraldry is science of knowledge of family symbols. Concretely it will be zoo, which will be focused on animals, which can be found on the old czech signs. The idea comes from surrounding relations of dramatic terrain and it's affected by context of the historic monument. Castle is the huge dominant of the all views to the surrounding countryside.

Residential Complex in Brno - Komín
Ertl, Jakub ; Čelikovský, Martin (referee) ; Makovský, Zdeněk (advisor)
Urban Risen Solution parcel located on the street Pasture in the city of Brno chimney. The property is located on the edge of the city district and directly continues the surrounding forest, which is on the east side. The plot is an avenue of chestnut trees that proposal preserves intact. Oklí are good amenities. In its narrowest surroundings there are elementary school and kindergarten with their priľahlími Sports and satellites family townhouses on the south side of the property. After the eastern and northern boundary leads IMPORTANT relaxing walking routes on which the proposal responds through-beds, and a "restoration" of pastures, which once was located here. Land would extend that oľúbenú Walking and served by community residents as well as the city of the chimney. The project also own community náveznosťou room with a plate of street furniture. Architectural design Material objects based on the elongated shape of the land and is divided into three apartment buildings. Distributes land to the "street" and the "grazing". The volume responds to building orientation sides are angled wings housing the south and west. All the apartments are so perfect sunlit and overlook the "pasture". On the north side of the building they are arranged in the form of communication zasklennej galleries. The porch with loggias flats made up of separate steel structure, which forms the form of these apartment buildings. The main module becomes one living room, ensuring good housing variability. The building is located only forty apartments of sizes 1 + kk to 5 + kk apartment with terrace. Parking is in the combined form of overhead and underground parking. Building Solutions The building is designed as a reinforced concrete skeleton with dimensions of 8600 mm x 6600 mm with stiffening communication core. The shell is insulated with thermal insulation with a thickness of 200 mm. Area building openings is minimized on the north facade and vice versa is open to south and west facades, which benefits the passive energy gain. These construction holes are filled with high quality aluminum windows and doors with Triple glazing. On the frame is attached a separate steel construction porches and balcony. This concept allows a perfect insulation shell fired by a separate steel structures unheated porch and balcony, and hence a considerable degree of energy efficiency.

Development of organic orcharding in the Czech Republic - current state and perspective
PREKOPOVÁ, Dagmar
This work was based on the topic development of organic horticulture in the Czech republic. The aim was to evaluate the development of organic horticulture in the Czech Republic and the applicable legal standards, predictions of future develop-ments. There is reviewed the current status of organic farming. There was surveyed by using a questionnaire about farming and views and ideas of organic fruit growers about the current legislation. I observed anticipated development under the Action Plan. According to the responses organic farming is now impossible to farm without subsidies. Another possible extension of the work would be talking with the orchar-dist a personal hearing, because the returning of the questionnaire was very low.
