Room 302 Engineering & Science Annex


Spent nuclear fuel (SNF) from commercial reactors poses challenges to reactor operators, regulators, and safeguards practitioners, due to the complex nature of isotopic evolution with time, radiotoxicity, decay heat, and high radiation emissions. This presentation provides an overview of the SNF attributes in the US and a broad range of research activities at ORNL to address issues related to SNF transportation, storage, and safeguards using both modeling and simulation (M&S) and SNF measurements. The presentation will provide a background of SNF, describe the challenges associated with SNF management, and discuss SNF M&S methods and selected verification and validation studies. The second half of this presentation will focus on SNF safeguards, including discussions of its challenges, limitations of current technologies, ongoing development of new advanced technologies, and incremental improvements to existing technologies. It will also describe a recent SNF measurement campaign at an ORNL hot cell to collect data for safeguards applications.

That campaign was featured in a recent episode of PHD Comics:
