  1. 1. Hur påverkas gölgrodan (Pelophylax lessonae) av translokering? : undersökningar av hemvändarbeteende och kroppskondition

    University essay from SLU/Dept. of Ecology

    Author : Maria Johansson; [2023]
    Keywords : amfibier; ekologisk kompensation; homing ; groddjur; inomartskonkurrens; kroppskondition;

    Abstract : För att Svensk kärnbränslehantering AB (SKB) ska kunna anlägga ovanjordsdelarna för det planerade kärnbränsleförvaret i Forsmark kommer en göl som hyser skyddsvärda groddjur som gölgroda (Pelophylax lessonae) att torrläggas och fyllas igen. För att kompensera för habitatförlusten har SKB anlagt nya gölar som gölgrodorna ska translokeras till. READ MORE

  3. 2. 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

  4. 3. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiar Afzalan; [2021]
    Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

    Abstract : The Swedish Nuclear Fuel and Waste Management Co. (SKB) started a project in 2020 near Forsmark, Sweden with the aim to expand the deformation zone model to encompass the entire catchment area around the planned repository for spent nuclear fuel. READ MORE

  6. 5. Compilation and evaluation of validations of computer codes for spent nuclear fuel – a review

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Staffan Fors; [2019]
    Keywords : Nuclear fuel; Kärnbränsle; Slutförvar; Fissionsprodukter; Physics and Astronomy;

    Abstract : This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. READ MORE
