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.”

Preliminary results from a nonlinear dynamic model of the Molten Salt Demonstration Reactor (MSDR) plant are presented. This model is coupled to an integral economizer Once-Through Steam Generator (OTSG) model with variable boiling length to simulate operation at different power levels. The reactivity effect of Xe-135 is also integrated to investigate open-loop load-following operation. Simulation results show that the reactor model is stable for the investigated reactivity perturbations. A load-following excursion is simulated by varying the feedwater flow rate through the steam generator. Results show that the MSDR can follow load demand in a stable manner through temperature-based reactivity feedbacks alone without requiring operator input. Future work involves development of instrumentation systems and control strategies to achieve near autonomous plant operation.
