First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

Scenarios of the evolution of the French nuclear fleet are developed by CEA, EDF, ORANO and FRAMATOME, following conservative assumptions in terms of technology, safety, regulation and costs. In the next decades, the SFR demonstrator ASTRID paves the way to the deployment of a few fast reactors used to consume PWR MOX spent fuel in priority. In the 2090 to 2120 period, the number of SFR goes on growing. The fleet eventually comes to a mix of breeder SFR and EPR (European Pressurized water Reactor) supplied with LEU and MOX fuels. Such a fleet composition enables the stabilization of spent fuel and plutonium inventories. Previously, a steady-state regime was reached in the next century, thanks to a fleet composed of ~40% SFR.
A new methodology has been applied. This methodology was recently developed to put into equations the equilibrium conditions of nuclear power systems composed of various reactor types. Fleets with the less SFR are now favored, since SFR are reputed to be more expensive than thermal reactors. Results show that the fraction of SFR in the fleet can be reduced of around 10% in comparison to the fleet previously deployed. However, the fleet composition which minimizes the SFR fraction at equilibrium leads to plutonium contents in EPR MOX fuels near the safety limit which is currently accounted for.
