ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

NEA issues call to action in report on nuclear cost reductions
A new report from the Paris-based OECD Nuclear Energy Agency declares that nuclear power is needed for countries to meet their Paris Agreement decarbonization and energy security policy goals, but that governmental support for a rapid reduction in the cost of new nuclear capacity through the creation of certain policy frameworks is likely necessary.

A team at the Budker Institute of Nuclear Physics has been working for several years to develop the Gas Dynamic Trap Mirror Neutron Source (GDT-NS) for fusion materials irradiation. In 2010 they optimized the design for a transmutation mission forecasting a 16 meter DT plasma with a fusion power of 15 MW and neutrons preferentially emitted into blankets placed around the mirror turning points. While this remains to be demonstrated experimentally, it is intriguing to explore what could be done with a low fusion power neutron source.
The GDT-NS team has previously modeled the burning of minor actinides. The work presented here builds on this by examining the burning of plutonium starting with transuranics recovered from spent nuclear fuel. It was found that a GDT plutonium burner with two blankets could eliminate nearly the plutonium produced in a single light water reactor core per full power year, 249 kg. By increasing the average blanket power with regular refueling, this quantity was increased to 381 kg per full power year. Next followed a preliminary overview of a GDT disposition blanket to meet US treaty commitments in burning surplus military plutonium.
