1. 6. New Materials for the Molten Carbonate Fuel Cell

   Författare :Sara Randström; Carina Lagergren; Michel Cassir; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molten Carbonate Fuel Cell; Anode current collector; Cathode; Wet-seal; Ionic liquid; TFSI; Smältkarbonatbränslecell; Anodströmtilledare; Katod; Wet-seal; Jonvätska; TFSI; Electrochemistry; Elektrokemi;

   Sammanfattning : Smältkarbonatbränslecellen (MCFC) är en högtemperaturbränslecell för stationära applikationer. Den har samma höga totalverkningsgrad som konventionella kraftvärme-anläggningar, men kan byggas i mindre moduler (från 250 kWe). LÄS MER

3. 7. Intermediate Temperature Solid Ionic Conductors and Fuel Cells

   Författare :Zhu Bin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molten phase; bulk and interfacial conduction; intermediate temperature; salt-ceramic composites; solid state proton conductors and fuel cells; blocked and non-blocked mobile species; ionic and protonic conduction and diffusion; oxyacid salts;

   Sammanfattning : Novel solid proton conductors based on oxyacid salts and salt-ceramic composites and intermediate temperature fuel cells have been developed in this thesis work. The discovery of proton conduction in these materials introduces a new concept of proton conductors and starts a new research field - Intermediate Temperature Solid Proton Conductors and Fuel Cells.

4. 8. Neutronics in reactors with propagating perturbations

   Författare :Anders Jonsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; Molten Salt Reactors; two-group theory; neutron noise; propagating perturbations;

   Sammanfattning : This thesis contains several studies of the properties of neutron noise, primarily in Molten Salt Reactors and other reactors with propagating perturbations. Both one- and two-group diffusion theory are employed to investigate the differences that arise from the movement of the fuel. LÄS MER

5. 9. Nuclear safeguards directed to the application of multivariate analysis techniques to existing and future nuclear fuel cycles

   Författare :Vaibhav Mishra; Sophie Grape; Zsolt Elter; Erik Branger; Peter Dendooven; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear safeguards; nuclear fuel verification; spent fuel; molten salt reactors; machine learning.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Sammanfattning : For as long as nuclear power has existed, there has been a concern for effectively safeguarding nuclear material since it was learned that it could be misused. Early on, many nations were interested in nuclear power, and therefore there was an urgent need to verify that it was only used for civilian purposes. LÄS MER

7. 10. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process

   Författare :Xinlei Ge; Seshadri Seetharaman; Katsunori Yamaguchi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte solutions; activity coefficient; osmotic coefficient; freezing point depression; boiling point elevation; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. LÄS MER
