  1. 1. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

  3. 2. Analysis of Mobility and Traffic Safety with Respect to Changes in Volumes; Case Study: Stockholm, Sweden

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Sofia Johansson; Sri Vasireddy; [2021]
    Keywords : Accident Rate; Mobility; Pandemic; Risk Analysis; Traffic Accidents; Traffic Flow; Traffic Safety; Unprotected Road Users;

    Abstract : The growing population and motorization generate more movements. In many cities, the increase of population and motorization is much greater than the development of the capacity of the transportation network. For unprotected road users, the risk of getting in a traffic accident increases and the risk of being more severely injured in an accident. READ MORE

  4. 3. Getting a grip on the effect of preventive public health interventions – A study of the economic benefits of subsidized ice cleats

    University essay from Göteborgs universitet/Graduate School

    Author : Joel Canderhed; Victor Abdalla; [2020-07-10]
    Keywords : QALY; ICER; ice grip; ; ice cleat; ; STRADA; STRADA; traffic; injury; quality of life; DID; Difference-in-Difference; subsidy; Intent-to-Treat; weather; gender; negative binomial regression;

    Abstract : Purpose: This thesis studies an ice cleat subsidy programme for seniors introduced in 2018 by Region Jönköping in Sweden. The aim of the study is to examine whether the subsidy was a cost-effective way of decreasing the number of Emergency room (ER) visits caused by snow and ice related fall injuries for seniors.

  5. 4. Improved methodology for postulated fuel handling accident

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Max Fagerberg; [2020]
    Keywords : ANSYS LS-DYNA; FEM; nuclear fuel; solid mechanics; Technology and Engineering;

    Abstract : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. READ MORE

  6. 5. Entertainement [!] for faster driving takeovers : Designing games for faster and safer takeovers on level 3 self-driving cars

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Luca Di Luccio; [2020]
    Keywords : Level 3 self-driving car; onboard entertainment; context switching; low fidelity simulator;

    Abstract : The upcoming level 3 generation of self-driving vehicles will be characterized by the freedom of not having the driver’s hands on the steering wheel. This acquired freedom is posing new challenges on the traditional passenger comfort paradigm as the drivers will spend a higher amount of time doing non-driving tasks (NDRT). READ MORE
