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 poloidal field (PF) power supply is an important subsystem of the EAST (Experimental Advanced Superconducting Tokamak as the device status detection and protection are essential. The PF power supply monitor system is based on the Experimental Physics and Industrial Control System and the human machine interface is the Control System Studio (CSS). The alarm is a plugin of CSS, used to help operators take correct action at the correct time. This technical note creates the alarm system, including server, client, Java Message Service interface, and relational database and configures the alarm attribute and sets the action for all variables that may trigger the alarm. When the alarm is triggered, the system goes into fault mode, the alarm server sends mail or pops up a window automatically to prompt operators, and some actions may be executed automatically to protect the device. Then operators solve the fault according to the guidance and the system returns to normal, realizing device status monitoring and protection in real time. The EAST experiment shows the alarm system has better function and stable performance.
