  1. 1. 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

  2. 2. Predicting Treatment Performance Using Ternary Plot : Macronutrients’ impact on biomass conversion efficiency

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Madeleine Gobl; [2022]
    Keywords : Black soldier fly; organic waste treatment; biomass conversion efficiency; treatment performance; macronutrients; ternary plot; organic waste; amerikansk vapensflugan; triangulär diagram; organiskt avfallsbehandling; organiskt avfall; behandlingseffektivitet; biomassomvandlings-effektivitet; makronäringsämnen;

    Abstract : Black soldier fly larvae (BSFL) waste treatment is becoming a more sought-after organic waste treatment since it produces larvae for animal feed as well as fertilizer, the need for prediction and optimization of treatment performance increases. This study aims to predict biomass conversion efficiency (BCE) for waste going into treatment, using only the nutritional data from other studies as it could give a good performance estimation while using available data.
