11. Numerical Investigations on Debris Bed Coolability and Mitigation Measures in Nordic Boiling Water Reactors
Sammanfattning : This thesis is aiming at coolability assessment of particulate debris beds formed in hypothetical severe accidents of Nordic boiling water reactors (BWRs) which may employ either lower drywell flooding or control rod guide tubes (CRGT) cooling as severe accident management strategies. For this purpose, quench and cooling limit (dryout) of debris beds after their formation from fuel coolant interactions were investigated by numerical simulations using the MEWA code. LÄS MER
12. Numerical predictions of heat-transfer applied to electrical machines
Sammanfattning : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. LÄS MER
13. A techno-economic system approach for the energy renovation of residential districts built before 1945
Sammanfattning : A key factor in the quest for sustainable development worldwide is reducing the energy use and greenhouse gas emissions from residential buildings. The residential and service sector represent 39% of the final energy use in Sweden. LÄS MER
14. Chemical composition of summertime High Arctic aerosols
Sammanfattning : This thesis presents new insights into the chemical composition of semi-volatile compounds in aerosol samples collected in the central Arctic Ocean close to the North Pole in September 2018. The central Arctic Ocean is an inaccessible location due to the lack of land areas along with heavy pack ice conditions. LÄS MER
15. Digitalising Tax, The Kenyan Way : The Travels and Translations of ITax in Kenya
Sammanfattning : Kenya, as with other developing countries, has joined the global bandwagon of using digital technologies to increase domestic revenues. Within the new strategies, lie great potential in achieving sustainable development, however, the shift is happening quite rapidly and has been made mandatory within a short period of time. LÄS MER
