- Automation modelling methods and their applications in nuclear power plant modernization projects
Sähkötekniikan korkeakoulu | Master's thesis(2015-05-11) Ukkola, HannaIn this thesis, a selection of automation modelling methods is presented, and the suitability of the methods for modelling a nuclear power plant instrumentation and control system modernization project is evaluated and compared. As an example, Advanced process simulation environment APROS is used in a case study to simulate, compare, and predict the mass flow behaviour of the current and the upcoming new main circulation systems of Olkiluoto 1 and 2 nuclear power plants. It is concluded that none of the presented automation modelling methods can alone model a full scale modernization project, but each of them have qualities that would benefit the modelling process during different phases. A combination can be formed out of the presented methods that would be suitable for modelling all the aspects of an extensive modernization project. APROS is determined to be advantageous for process simulation, but its automation modelling capabilities are deemed incomplete as of now. However, a working example is constructed, and the created models are verified to be reliable enough for the case study requirements. - Kontinuumimanipulaattorin innovatiiviset tarttujat kotiympäristössä
