341. Preparations for redox studies of seaborgium with SISAK coupled to the flow electrolytic column FEC

Prof. Jon Petter Omtvedt (University of Oslo, Department of Chemistry)

Separation Methods, Speciation

Invited

An important motivation for investigating chemical properties of the transactinide elements is whether the Periodic Table keeps its validity as an ordering scheme in the transactinide region, i.e. for element number 104 and onwards. Strong relativistic effects, which increase approximately as a function of Z2 and are thus most pronounced in the heaviest elements, are expected to make the...

141. Isolation of Ho-163 from Dy target material by HPLC for Neutrino Mass Measurements

Ms Veronika Mocko (Los Alamos National Laboratory, Los Alamos, NM, USA)

Verbal

The rare-earth isotope Ho-163 is of interest for neutrino mass measurements. The experimental evidence for neutrino and antineutrino oscillations between flavor states is compelling, with extensive implications for astrophysics, nucleosynthesis, the origin of dark matter and cosmology [1]. The goal of our experiment is to investigate the electron neutrino mass by a high precision and high...

62. Characterization of the extraction properties of the selected extraction sorbents TRU, TEVA, UTEVA and DIPHONIX

Dr Jiří Janda (University of defense)

Separation Methods, Speciation

Verbal

The possibility of misusing heavy unstable elements, especially transuranic elements, for military or terrorist purposes, their involvement in nuclear accidents or in fuel cycle makes them elements of interest. Among the most important elements belong uranium, plutonium, americium and curium. These radionuclides are both military significant and also important for nuclear safety. The paper...

47. Development of mutual separation method of Zr, Nb, and Mo with extraction chromatography using TEVA resin

Dr Asako Shimada (Nuclear Cycle Backend Directrate, Japan Atomic Energy Agency)

15/05/2014, 11:30

Separation Methods, Speciation

Verbal

The reactors at Fukushima Daiichi Nuclear Power Station were damaged severely because of the accident. Cooling water is leaking from the reactor vessels and groundwater is flooding into the basement of reactor and turbine buildings. Consequently, contaminated water is accumulating. The accumulated water processing facility was installed to decontaminate the radionuclides and to desalinate. As...

23. Palladium extraction by malonamides

Remi Poirot (CEA)

Separation Methods, Speciation

Verbal

Recycling of valuable metals appears as solution of growing interest for a sustainable supply strategy nowadays. Palladium (Pd), along with other platinum group metals (PGM) and rare earth elements (REEs), represents one of the crucial issues in recovery processes. Malonamides are neutral amphiphilic molecules which have proved their potency for the extraction of f-elements and the recovery of...
