  1. 1. A VVER1000 primary side model in Apros

    University essay from KTH/Fysik

    Author : Karl-Edvin Strand; [2023]
    Keywords : Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Abstract : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

  3. 2. BWR Reactor Fuel Channel Manufacturing Simulations

    University essay from KTH/Hållfasthetslära

    Author : Kalle Norell; [2022]
    Keywords : Bending; Boiling water reactor; Fuel channel; FEM; Bockning; Kokvattenreaktor; Höljerör; FEM;

    Abstract : Fuel channels are used to keep the components of a nuclear fuel bundle in place. The fuel channel of a new nuclear fuel which is being developed at Westinghouse has a complex geometry which creates challenges in the manufacturing process. FE simulations were developed of a two-stage forming process of the fuel channel. READ MORE

  4. 3. Power Increase Limits to Prevent Pellet-Cladding Interaction : Calculation of Strain- and Fission Gas Release Margins

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Viktor Nerlander; [2022]
    Keywords : pci; fuel damage; FRAPCON; FRAPTRAN; FPO;

    Abstract : With a growing share of intermittent electrical energy sources in the national grid of Sweden, areview of the safety of using nuclear power for flexible operation is necessary. Today nuclearpower is used as base load power and when examining challenges of flexible power operation,the risk for Pellet-Cladding Interaction (PCI), stands out. READ MORE

  5. 4. Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods

    University essay from KTH/Fysik

    Author : Jonathan Al-Ani; [2021]
    Keywords : APROS; Dynamic process simulation; System code; Nuclear reactor; nuclear power; BWR; Boiling Water Reactor; closed cycle; steam cycle; one-dimensional flow; Westinghouse; control rods; APROS; Dynamisk processimulering; Beräkningsmodell; Kärnkraft; BWR; Kokvattenreaktor; ångcykel; en-dimensionell flödesmodell; Westinghouse; kontrollstavar;

    Abstract : In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). READ MORE

  6. 5. Mathematical modelling of Degussa Furnace

    University essay from KTH/Materialvetenskap

    Author : Rans Faraydoun Muhammed; [2021]
    Keywords : Furnace; CFD; ANSYS; Thermodynamic model; Exchange time; Ugn; CFD; ANSYS; Termodynamisk model; Utbytestid;

    Abstract : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. READ MORE
