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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Nuclear aerosols can originate from severe core damage in light water reactors, core disruptive accidents in fast reactors, nuclear accidents during nuclear material transport, at waste disposal sites, or from explosions and can evolve under natural transport processes as well as under the influence of engineered safety features. Such aerosols can be hazardous for the equipment inside the reactor and when leaked to the environment pose potential risks to the public. However, the computation of aerosol evolution is complicated, and an exploration of the direct simulation Monte Carlo technique to elucidate the role of various physical phenomena that influence the evolution, and eventually to help develop a production computer program, has been undertaken. We have extended here the previous work in important new directions by including most coagulation mechanisms such as Brownian, gravitational, and turbulence. We have also explored the Metropolis algorithm for sampling particles. We have found that the Metropolis algorithm permits efficient simulation of a much larger number of particles because it does not require precomputation and periodic update of the collisional matrix after each collision, unlike the direct sampling method.
