Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Update: Senate includes $250k for EPA generic repository
The U.S. Senate’s proposed Department of the Interior funding package provides $250,000 to develop a generic, technology-neutral standard for future high-level nuclear waste disposal facilities.
The goal is for the Environmental Protection Agency to use modern and international practices in creating new plans to store U.S. nuclear waste. This spring, the EPA had requested $635,000 to fund this work—but even the proposed $250,000 would help get the process moving.
So far, funding has been included only in the Senate’s version of the appropriations bill, but supporters hope it makes the final package when Senate and House lawmakers conference on the final fiscal year 2025 appropriations legislation this fall.

A part of the recent scoping studies for a European DEMO reactor deals with the design of the in-vessel components and their integration inside the reactor. The main in-vessel components are the Breeding Blankets (Helium Cooled Lithium Lead and Helium Cooled Pebble Bed), the helium supply units called Manifolds (MF) and the Neutron Shields. Alternative concepts for the integration of these components have been developed in parallel by different Europe an associations (FZK, CEA, and EFET). Nevertheless these concepts are all based on the vertical segmentation concept called "Multi Module Segment" (MMS). The big advantage of the MMS concept dwells in the fact that blankets and MF constitute a vertical non-permanent segment to be installed and dismantled by Remote Handling (RH) tools through the upper ports of the reactor. The dimensions, geometry and materials are strictly dependent on the harsh conditions of the in-vessel environment: high temperatures, high neutron fluxes, and high thermo-mechanical loads during normal operations and disruptive events. In addition, suitable systems of attachment able to withstand thermal expansion and the expected loads have been developed to provide reliability and easy in-vessel maintenance. The general aspects of the MMS system and the common RH procedures foreseen are presented and the different specific options for solving attachment and in-vessel assembly issues are discussed.
