1. 16. Power generation and stability of the Swedish electricity system 2045

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Samir Rawashdeh; [2023]
   Keywords : Duck curve; peak load; capacity factor; availability factor; stability; synthetic inertia; flexibility; ancillary services; solar power; wind power; hydropower; co-generation; heat generation; nuclear power; hydrogen production; electrolysis; fuel cells; V2G; PtG; P2G; P2G2P; ESS; PSH; SMR; NPP; HPP; FFR; Technology and Engineering;

   Abstract : På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. READ MORE

3. 17. Feasibility of HALEU-loaded Breed-and-Burn Molten Salt Fast Reactor without Online Actinide Treatment

   University essay from KTH/Fysik

   Author : Lei Shi; [2023]
   Keywords : Molten salt; Chloride fuel; Fast reactor; Breed-and-Burn; Smält salt; kloridbränsle; snabbreaktor; avel och bränning;

   Abstract : Molten Salt Fast Reactors (MSFRs) have prominent advantages such as fuel breeding, nuclear waste transmutation, and inherent safety. They are the only liquid-fueled nuclear reactors currently receiving significant attention as fourth-generation advanced nuclear systems. READ MORE

4. 18. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Amela Mehic; [2022]
   Keywords : Nuclear physics; Calorimeter; SNF; MCNP; Dose rate; CLAB; Gamma energy; Fuel assembly; Form function; Attenuation coefficient; Gamma spectroscopy;

   Abstract : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. READ MORE

5. 19. Spent Nuclear Fuel under Repository Conditions : Update and Expansion of Database and Development of Machine Learning Models

   University essay from KTH/Kemi

   Author : Maria Abada; [2022]
   Keywords : Spent nuclear fuel; spent nuclear fuel dissolution; spent nuclear fuel corrosion; machine learning model; dissolution predictions; Utbränt kärnbränsle; upplösning av utbränt kärnbränsle; korrosion av utbränt kärnbränsle; maskininlärningsmodeller; prediktioner av upplösning;

   Abstract : Förbrukat kärnbränsle är mycket radioaktivt och behöver därför lagras i djupa geologiska förvar i tusentals år innan det säkert kan återföras till naturen. På grund av de långa lagringsperioderna görs säkerhetsanalyser av de djupa geologiska förvaren. READ MORE

6. 20. 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
