Design, analysis and determination of the conduites support types for Nuclear power plant Krško

V diplomskem delu je obravnavana zasnova, analiza in določitev tipov podpor konduitov za Nuklearno elektrarno Krško (NEK). Podpore so iz jeklenih HEA-profilov ter U-profilov, ki so znotraj stavb NEK-a. Podpore so pritrjene na betonski strop, nanje pa so z vijaki pritrjene objemke, namenjene opori konduitov. Podpore so dimenzionirane na podlagi evropskih predpisov za dimenzioniranje konstrukcij Evrokod ter tudi po ameriških standardih AISC. Izvedena je primerjava med obema standardoma. Pri analizi je pomembno upoštevanje potresa, saj je to pomembna zahteva Nuklearne elektrarne Krško. Za izračun reakcij smo uporabili program Tower 6, pridobljene podatke pa smo uporabili za preveritev nosilnosti elementa konduitov, kar smo izvedli ročno z uporabo obeh standardov. Zvare smo prav tako preračunali ročno po obeh standardih, sidranje sidrnih plošč z vijaki pa smo preverili s pomočjo računalniškega programa Hilti. Rezultati kažejo na manjše razlike med standardoma. Ugotovili smo, da je ameriški standard nekoliko bolj strog od evropskega.The graduation thesis deals with design, analysis, and determination of the conduits support types for Krško Nuclear Power Plant (NEK). Supports are made of steel HEA profiles and U profiles, and are located within the NEK’s buildings. Supports are attached to the concrete ceiling. Using screws, clamps, which are used to support conduits, are attached to the ceiling. Supports are dimensioned on the basis of European regulations on dimensioning constructions Eurocodes, as well as according to the American standards AISC. We also carried out comparison among both standards. In analysis, it is important to consider earthquake, since this is an important demand of the Krško Nuclear Power Plant. To calculate reactions, we used Tower 6 program, and the obtained data were used to check the carrying capacity of the conduit elements, which was performed manually using both standards. We also calculated welds manually according to both standards, and anchoring of both anchor plates was checked using Hilti computer program. Results reveal minor differences among the standards, namely that the American standard is slightly stricter than the European one
