Description

(1st ASGARD International Workshop)

451. ASGARD, a 15 month update

Prof. Christian Ekberg (Nuclear Chemistry, Chalmers University of Technology, Gothenburg, Sweden)

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Invited

The ASGARD project (Advanced for Generation IV reactors: Reprocessing and Dissolution) started in January 2012. Its main goal is to understand and bridge the gap between the fuel reprocessing/separation community currently represented by the ACSEPT project and the fuel manufacturing and irradiation community currently represented by the FAIRFUELS project. The main goal is to investigate the...

253. New Fluorinated Diluents for Tributylphosphate

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Verbal

The extraction ability of ligands strongly depends on the type of the diluent. The fluorinated compounds provide an opportunity for variation of diluents structure and polarity. Different types of fluorinated compounds (alcohols, ethers and other fluorinated aromatic compounds) were tested as diluents for bidentate organophosphorus compounds, chlorinated cobalt dicarbollide and crown ethers....

277. Dynamic Test of New Extraction System – TODGA in Meta-Nitrobenzotrifluoride

Dr Vasiliy Babain (Khlopin Radium Institute)

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Verbal

Tetraoсtyldiamide of diglycolic acid – (TODGA) is actively studied as promising extractant for actinide separation. Extraction properties of TODGA in various diluents were studied. It was shown, that maximal metal concentration in the organic phase can be achieved when meta-nitrobenzotrifluoride ( F-3) was used as a diluents. Actinide and lanthanide extraction from HLW by 0.2 M TODGA in F-3...

380. Co-conversion of minor actinides in uranium based oxidic precursors by internal gelation

Mr Christian Schreinemachers (Forschungszentrum Jülich GmbH)

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Verbal

In the context of advanced nuclear fuel cycles including partitioning and transmutation (P&T), actinide co-conversion processes, such as sol-gel routes, play an important role to close the fuel cycle. During the heterogeneous recycling of minor actinides, oxidic materials containing uranium as main matrix are used as innovative nuclear fuels. Advanced fuel concepts replace the conventionally...

390. Ceramic Waste Forms for the conditioning of Minor Actinides

Dr Stefan Neumeier (Forschungszentrum Jülich GmbH)

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Verbal

The disposal of high level radioactive waste is one of the most pressing and demanding challenges. With respect to long-term safety aspects of geological disposal, the minor actinides (MA) such as Am, Cm and Np and long-lived fission products such as 35Cl, 135Cs, 79Se, 90Sr and 129I may be of particular concern due to their long half-lives, their high radiotoxicity and mobility in a repository...
