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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.
18th International Probabilistic Safety Assessment and Analysis (PSA 2023)
Workshop
Sunday, July 16, 2023|12:00–5:00PM EDT|Marriott Knoxville Downtown
Max. Attendees: 50
Description: Dynamic PRA methodologies explicitly account for the time element in probabilistic system evolution and heavily incorporate plant analysis/simulator tools to model possible dependencies between failure events that may arise from hardware/software/firmware/process/ human interactions. Dynamic PRA methodologies can also quantify the effects of phenomenological variability and model uncertainties on the consequences of upset conditions. They can benefit the PRA modeling of passive systems, including the representation of aging effects and digital instrumentation and control systems.
The workshop's objective is to provide a perspective on dynamic PRA methodologies, the circumstances under which they may be needed, and the existing challenges with their deployment. The use of some of the available software tools will be demonstrated.
