  1. 1. Analys av brandspridning inom probabilistiska säkerhetsanalyser använda i kärnkraftsindustrin

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Fredrik Wennberg; Elias Karlsson; [2019]
    Nyckelord :Brandspridning PSA; brandspridning kärnkraft; brandspridning screening; screeningkriterium brand; fire spread PSA; fire spread nuclear facility; fire spread screening; screening criteria fire; Technology and Engineering;

    Sammanfattning : The work presented in this report was based upon two different stages, with the aim of coming up with an improved screening process concerning fire spread within PSA at Ringhals Nuclear Power Plant in Sweden. The first phase consisted of creating a methodology for the screening process, which was based on various screening data, such as CDF, fire loads and openings between compartments. LÄS MER

  2. 2. Influence of ventilation on ro-ro space fire development : A study using two-zone fire models in order to explore tendencies of how different ventilation parameters affects the fire development in a ro-ro space

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

    Författare :Martin Lindgren; Andreas Lilja; [2019]
    Nyckelord :Fire; Ro-ro space; Ventilation; Simulation; Two-zone model; Brand; Rorolastutrymme; Ventilation; Simulering; Tvåzonsmodell;

    Sammanfattning : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.

  3. 3. Planlösning i bostäder som en del av det passiva brandskyddet

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Andreas Stagnebo; Axel Philip; [2017]
    Nyckelord :Floor plans; fire protection; CFD; FDS; CFAST; case study methodology; hand calculation methods; fire statistics; residential dwellings; planlösning; brandskydd; fallstudie; handberäkningsmetoder; brandstatistik; bostäder; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to investigate the impact of floor plan parameters in a residential dwelling regarding the consequences of fire that may endanger human life and health. The thesis follows a case study methodology and investigates isolated parameters in floor plans using CFD and CFAST modelling. LÄS MER

  4. 4. Brandteknisk riskvärdering av Högsboanstalten, byggnad F

    L3-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Sara Vallentin; Karolina Lundh; Gustav Wallgren; Albin Simonsson; [2015]
    Nyckelord :Högsboanstalten; intern; personal; utrymningstid; kritiska förhållanden; CFAST; FDS; ERM; Technology and Engineering;

    Sammanfattning : The following report contains a fire safety evaluation of Högsboanstalten in Gothenburg. The purpose of this report is to analyse different fire scenarios to see if the chosen building can be evacuated safely in case of fire. This is done by comparing total evacuation time with the time until critical conditions have been reached. LÄS MER

  5. 5. Gångavstånd till utrymningsvägar : En studie om gångstånden till utrymningsvägar och dess dimensioneringsmöjligheter med hjälp av förenklad dimensionering

    Författare :Stefan Ullström; [2015]
    Nyckelord :distance; evacuations; routes; fire; dimensioning; housing; building and planning; gångavstånd; utrymning; branddimensionering; Boverket;

    Sammanfattning : ABSTRACTThe title of this degree project after  three years long education of construction engineering is “Distances to evacuation routes” with the subtitle “A study of walking distances to escape routes and its design possibilities using simplified dimensioning”. The idea for the project came from the company Fire AB in Västerås. LÄS MER
