Separation of Transplutonium Elements from Neutron Irradiated Americium-241

Electrochemical Separation of Curium and Americium

The objective of this project is to develop a method for the separation of Am from Cm based on electrochemical techniques. Electrochemical systems that allow the thermodynamics of actinide and lanthanide complexes to be systematically evaluated and tuned will be examined. The influence of complex formation on the ability to selectively isolate a given species electrochemically will be evaluated...

Separation of Uranyl Nitrate Hexahydrate Crystal from Dissolver Solution of Irradiated Fast Neutron Reactor Fuel

A study on separation of 99Mo from neutron-irradiated UO2 by precipitation as ammonium molybdophosphate.

pharmaceuticals has increased so rapidly in the past few yearsl) that the production and the supply of 99Mo are one of the most important missions of an organization for radioisotope production. Molybdenum-99 having enough high specific activity for the medical application can be produced by nuclear fission of 235U. For the separation of 99Mo from fission products have been reported various met...

Measuring Neutron Separation Energies Far from Stability

A method is proposed for the experimental measurement of neutron separation energies for nuclei far from stability. The procedure is based on determining cross sections for the production of nuclei, by projectile fragmentation, for which only protons are removed but for which the number of neutrons is left unchanged. A simple Abrasion-Ablation analysis leads to a cross section prediction which ...

Fast Neutron Irradiated Magnetite and Haematite Investigated by Neutron Diffraction

In this paper, we present new experimental results about crystallographic and magnetic properties obtained on magnetite Fe,04 and haematite a-FqO, samples irradiated by fast neutrons. Polycrystalline rods were irradiated at 350K by fast neutrons inside the core of Melusine nuclear reactor (CENG) in Grenoble at various fluences (4 lO", 9.2 1019 and 20 10'' neutronslcm~). The irradiated samples h...
