Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

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

A breeder blanket, whose purposes are to breed tritium and to produce thermal energy, is indispensable for a fusion reactor. In addition to demonstrating the physics of burning D-T plasmas, an experimental reactor such as the ITER will also conduct a verification test of a blanket design. An in-pile functional test has been considered to obtain above engineering data since 1992 in the JMTR project. The sweep gas system which is a system to measure and recover the tritium released from a blanket mock-up has been designed. From the results of the design, the sweep gas system will be sufficient for the in-pile functional test in the JMTR.
