1. 6. Constitution, dynamics and structure of binary and ternary actinide complexes

   Författare :Wenche Aas; KTH; []
   Nyckelord :;

   Sammanfattning : Stoichiometry, ligand exchange reactions, coordinationgeometry and stability of complexes of type UO2LpFq(H2O)3-n(p= 1–2,q= 1-3), where L is one of the bidentate ligandspicolinate, oxalate, carbonate or acetate have beeninvestigated using single crystal X-ray diffraction, an arrayof19F-,13C-,17O- and1H-NMR techniques and potentiometric titration usingboth F-and H+selective electrodes. The experiments wereperformed in a 1. LÄS MER

3. 7. Development of a Solvent Extraction Process for Group Actinide Recovery from Used Nuclear Fuel

   Författare :Emma Aneheim; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Partitioning; Solvent Extraction; Fission Products; TBP; BTBP; GANEX;

   Sammanfattning : When uranium is used as fuel in nuclear reactors it both undergoes neutron induced fission as well as neutron capture. Through successive neutron capture and beta decay transuranic elements such as neptunium, plutonium, americium and curium are produced in substantial amounts. LÄS MER

4. 8. Neutronic and burnup studies of accelerator-driven systems dedicated to nuclear waste transmutation

   Författare :Kamil Tucek; Jan Wallenius; Massimo Salvatores; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik;

   Sammanfattning : Partitioning and transmutation of plutonium, americium, and curium is inevitable if the radiotoxic inventory of spent nuclear fuel is to be reduced by more than a factor of 100. But, admixing minor actinides into the fuel severely degrades system safety parameters, particularly coolant void reactivity, Doppler effect, and (effective) delayed neutron fractions. LÄS MER
