  1. 6. Investigation of coarse-grid CFD approach for nuclear engineering application

    University essay from KTH/Fysik

    Author : Michela Casarella; [2023]
    Keywords : Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

    Abstract : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

  3. 7. Pre-study for SMR and Nuclear Establishment in Norway

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Johan Stefan Nordström; [2023]
    Keywords : Energy mapping; Nuclear power; SMR; small modular reactors; siting; Norway; Energy; Technology and Engineering;

    Abstract : Norway has Europe’s highest share of renewable electricity production and the lowest power sector emissions. Thanks to the country’s stable power production, Norway has affordable and stable access to electricity, leading to industries choosing to relocate to the country. READ MORE

  4. 8. Model-Level Timing Analysis for UML-RT Capsules

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Niclas Ståhlbom; [2023]
    Keywords : computer science; software engineering; algorithm; real-time; real-time systems; UML-RT; capsule diagram; WCET; analysis; WCET analysis;

    Abstract : Real-time systems surround every facet of our lives. They can be found in anything from everyday objects like mobile phones and washing machines to objects critical to life and infrastructure including heart rate monitors and nuclear power plants. As time progresses these systems are becoming ever more complex. READ MORE

  5. 9. Reliability Assessment of Passive ICS in an SMR as part of the PSA Analysis

    University essay from KTH/Fysik

    Author : Graeme Trundle; [2023]
    Keywords : Passive system reliability; Probabilistic safety assessment; Reliability Methods of Passive Systems; Natural circulation; TRACE; RiskSpectrum; Passiv systemtillförlitlighet; Probabilistisk säkerhetsbedömning; Reliability Methods of Passive Systems; Naturlig cirkulation; TRACE; RiskSpectrum;

    Abstract : Passive safety systems are increasingly being utilized in prospective nuclear power plant designs. Indeed, the use of safety systems driven by natural phenomena might be seen as an unmitigated virtue. READ MORE

  6. 10. Start of a new design method for a competitive Small Modular Reactor (SMR) adaptable to future uses

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Baptiste Mazurié; [2023]
    Keywords : Requirement modelling; Cyber-physical systems; Small Modular Reactor SMR ; Systems Engineering; CRML;

    Abstract : As cyber-physical systems become increasingly complex, the management and verification of requirements during design is essential. A new language called CRML (Common Requirement Modelling Language) has been created during the European EMBrACE project to formalize realistic dynamical requirements, but a method for representing these requirements and a framework for using them as a design aid must be defined to ease appropriation by engineers.
