  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. 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

  4. 3. Load following in a Swedish nuclear power plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Jacob Bjurenfalk; [2020]
    Keywords : chemical engineering; nuclear power; load following; process engineering; electricity production; APROS; Simulations; swedish power gird; kemiteknik; Technology and Engineering;

    Abstract : The energy system in Sweden is currently under a great transformation, where the part of weather dependent energy sources, so called intermittent sources, like solar and wind power will get greater share in the total production of electricity while the production from stable energy sources like nuclear power is decreasing. For a long time, the nuclear power have been operating at baseload and the hydropower as flexible, though, due to the change in the current power system, nuclear power plants may need to transit to flexible operation and apply load following.

  5. 4. Impact of thermal equilibriumassumption on modelling of coreuncovery in FIX-II experimentby APROS

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Albert Linder; [2018]
    Keywords : APROS 6-Equation 3-Equation model Homogenus FIX-II Thermal equilibrium;

    Abstract : When simulating a thermohydraulic system, the general assumption isthat the conservation equations for mass, energy and momentum apply.And in such systems both liquid and gas exist, in this project liquidwater and steam. This report examines two different approaches tosimulate a thermohydraulic system. READ MORE
