Nuclear Chemistry, Radionuclide Production, High-Power Targetry
Invited Lecture
Researchers at the University of Alberta have demonstrated that it is possible to produce and extract clinically significant quantities of 99mTc via the 100Mo(p,2n)99mTc nuclear reaction. Cyclotron targets have been engineered which significantly enhance their power-handling capacity to allow for extended high current irradiation. In addition, a process has been developed which allows for the...

Nuclear Chemistry, Radionuclide Production, High-Power Targetry
Invited Lecture
At iThemba LABS, proton beams of 66 MeV are used for the routine production of radionuclides and for neutron therapy. Between treatment irradiations, the beam is switched to the radionuclide production vaults and vice versa. Dedicated beam time for radionuclide production is also scheduled at night.
In recent years, several facility upgrades and new additions had been geared towards...

Nuclear Chemistry, Radionuclide Production, High-Power Targetry
Invited Lecture
The isotope production facility at 160 MeV proton beam of linear accelerator in the Institute for Nuclear Research of Russian Academy of Sciences (Troitsk) has the following characteristics providing high power irradiation:
- 4-cooling of the targets (from 1 to 14 targets at one time);
- slanting 26o-angle beam on the target;
- lithium beam window between accelerator vacuum and...

Invited Lecture
Large scale production of isotopes proceeds at the Isotope Production Facility (IPF) of the Los Alamos National Laboratory (LANL), using intense 100 MeV proton beams. The main metric of this program’s success is the reliable time-critical delivery of large quantities of high-purity medical isotopes, which in turn depends upon many aspects including robust high power targetry, availability of...

Nuclear Chemistry, Radionuclide Production, High-Power Targetry
Invited Lecture
ARRONAX, acronym for "Accelerator for Research in Radiochemistry and Oncology at Nantes Atlantique", is a high energy (70 MeV) and high intensity multi-particle cyclotron located in Nantes (France). It is designed to be able to extract two proton beams simultaneously (dual beam mode) up to 2*375µA. Beams can be delivered into 6 experimental vaults: Four are devoted to radionuclide production...

Nuclear Chemistry, Radionuclide Production, High-Power Targetry
Invited Lecture
Our program is presently investigating the production of 67Cu, 86Y and 225Ac. The half life and beta emission of 67Cu have long been recognized as attractive for radioimmunotherapy. The short lived positron emitter 86Y should be useful for patient dosimetry measurement prior to high dose 90Y immunotherapy. The alpha emitter 225Ac may be attractive for treatment of micrometastases, but supply...

Lead-Bismuth Eutectic has been proposed as spallation neutron target and as a coolant for Accelerator-Driven System. One of the main issues of using LBE is related to the production of Polonium and its potential release.
Tellurium was chosen as surrogate in order to designing experimental set-ups for investigating gas-phase chemical properties of Polonium and its compounds.

Oral Communications
Reducing the long-term radiotoxicity and heat load of spent nuclear fuel by separating long-lived radionuclides and converting them into shorter lived or stable nuclides by fast neutron induced fission reactions is the aim of the so called partitioning and transmutation strategy (P&T).[1] Key step is the separation of the trivalent actinides Am(III) and Cm(III) from the trivalent lanthanides...
