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.”

GeN-FOAM is a multi-physics solver based on the OpenFOAM library developed at PSI/EPFL, Switzerland for transient analyses of fast reactors. The current version of GeN-FOAM can simulate a wide range of transients with flexible spatial resolution. One of the main limitations of the current version, however, is relatively simple fuel temperature calculation model. Also, the effects of fuel structural and dimensional changes as a function of temperature, composition and burnup are currently not considered. This work first presents the integration of an advanced fuel performance modelling tool TRANSURANUS developed at Joint Research Centre (JRC)-Karlsruhe into the GeN-Foam solver. The new coupled tool is referred to as the GeN-transFoam. The original GeN-Foam doesn't have burnup calculation capability which makes it very inconvenient to simulate a reactor at the end of cycle, especially when an accurate fuel behaviour prediction is expected. The paper reports a simple way to implement the burnup calculation, given the configuration of the GeN-Foam solver. The GeNtransFoam solver with account for burnup effects is used to analysis the European Sodium Fast Reactor (ESFR) at the end of cycle (EOC) in steady state condition. The neutronics calculation results are compared with results provided by Monte Carlo calculation. In the end, the burnup calculation in the code is discussed.
