Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The feasibility of using a radio-frequency quadrupole (RFQ) accelerator to accelerate 3He++for use in positron emission tomography (PET) is shown. The 3He++ RFQ is extremely lightweight in comparison to a cyclotron, but can nevertheless produce all four radioisotopes of interest (18F, 13N, 15O, and 11C) in more than adequate quantities. Due to the neutron-poor nature of 3He++, the desired positron emitters can be produced from naturally abundant target isotopes. In addition, target reactions and collisions with the accelerating structure produce relatively small numbers of neutrons compared to proton and deuteron systems. This yields two economic advantages. Enriched 13C, 15N, and 18O target materials are not required. Also, the shielding requirements are reduced considerably, and there is no need for radiation shielding around the accelerator. This reduced shielding results in a factor of 8 reduction in total facility shielding weight compared to a proton/deuteron cyclotron facility. The order of magnitude reduction in facility weight, the virtual elimination of the accelerator weight, and the relative lack of residual induced activity gives rise to the possibility of a radiopharmaceutical production system that is less expensive than present systems and may ultimately be transportable. Such a system could make PET imaging technology far more accessible geographically and financially than it is at present.
