Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

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.”

A new concept for the transmutation of fission products and transuranics is studied. This concept, termed HYPERFUSE, allows one inertial reactor to transmute objectionable fission products (137Cs and 90Sr) from a large number (e.g., ∼30) of light water fission reactors, while at the same time generating electric power from the HYPERFUSE plant at a reasonable net plant efficiency (e.g., ∼30%). The cost of transmutation should be relatively low compared to other fission waste transmutation concepts due to the high support rate (number of fission reactors per HYPERFUSE reactor) and the effective generation of power by the HYPERFUSE reactor. Although the HYPERFUSE concept offers the possibility of a very effective means for waste transmutation and significant reductions in both high-integrity waste storage (burial) time and long-term risk potential, hazards will be introduced by such a system due to chemical processing and handling of radioactive materials in the recovery, partitioning, and fabrication stages as well as process and accidental losses. Such process risks need to be quantified for both conventional and advanced, chemical, and isotopic separation methods in order to evaluate the overall advantages and disadvantages of such a system. A system such as HYPERFUSE, however, leads to a quantifiable set of near-term risks for the nuclear waste problem, and a possibility of the elimination of a need for long-term nuclear waste disposal over a time scale of 106 years.
