Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

The design of the ITER tritium systems must ensure that the public is protected from operational and accidental tritium release and that worker exposures are minimized. The ITER public exposure limits are consistent with international recommendations and the As Low As Reasonably Achievable (ALARA) concept is being implemented. We describe design approaches that will allow us to achieve these objectives. Although the design is still in its early stages, we have estimated the tritium flows and inventories and have started the safety analysis. Operational and accidental releases from ITER have not yet been determined, but we have used experience from other facilities to estimate ITER releases.
