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.”

Multiregion heat transfer analyses, based on both laminar and slug flows, have been performed to explore the heat transfer characteristics of the rods located in the corner and edge regions of LMFBR nuclear fuel subassemblies. By adopting physical parameters of practical interest, the rod-average Nusselt numbers of these rods were calculated for equilateral triangular arrays of rods having pitch-to-diameter ratios in the range 1.05 ≤ P/D ≤ 2.00. A mathematical scheme is presented for determining the laminar velocity field which, in this case, constitutes a mixed boundary-value problem specified in a domain of irregular shapes. For the special cases of peripherally uniform temperature or uniform heat flux at the outer wall of the cladding, rod-average Nusselt numbers were also calculated and compared with those for central rods.
