  1. 16. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

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

    Sammanfattning : 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. LÄS MER

  3. 17. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :David Aronsson Edström; Oskar Lundberg; [2022]
    Nyckelord :3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Sammanfattning : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. LÄS MER

  4. 18. Modelling of a Heat Conduction Calorimeter Used in Cement Plant Automation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Hassan Alzeidi; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. LÄS MER

  5. 19. Rökpartiklars storleks beroende av syrehalt

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Karl Wendt Höjer; [2022]
    Nyckelord :Particle size – Hypoxic – CACC – Reducerad syrehalt – Cone calorimeter – Multi-wavelength light transmission measurements - Partikelstorlek; Technology and Engineering;

    Sammanfattning : Particle size can be an important variable to know in many different areas, be it smoke simulations, toxicity of materials or tests of face masks. Fires in a reduced oxygen environment can occur for ventilation-controlled fires or in areas with artificially lowered oxygen levels. LÄS MER

  7. 20. The Heat reducing Effects of Reflective Clothing in Firefighting : A study on the efficiency of reflective textiles in personal protective equipment

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Albin Henning; [2022]
    Nyckelord :Firefighter; Reflective textiles; Radiant heat; Protective equipment;

    Sammanfattning : Modern firefighter protective equipment is excellent at protecting firefighters from surrounding heat, but how effective is at deflecting incoming radiant heat, and would the use of more reflective textiles, be able to further increase the equipment’s protective properties? This study aims to understand the different properties that reflective materials, compared to standard firefighter outer layers, have against radiative heat flux. The textiles of firefighter turnout gear and the reflective textiles used in the smelting industry have been examined when exposed to varying levels of radiant heat in a cone calorimeter. LÄS MER
