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.
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.

Retrieval of nuclear waste canisters from a borehole
Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

The passive safety strategy for fusion can be summarized as three options: Inventory-based passive safety, Mobility-based passive safety, and Confinement-based passive safety. The determination of the dose limits for the public must follow a risk-based approach, where “risk” is the product of frequency times consequence. Ignitor is a high magnetic field tokamak, aimed at studying the physics of ignited plasmas. The site chosen for construction is the nuclear site of Saluggia (Northern Italy). The safety goal for Ignitor is the classification as a mobility-based passively safe machine. This choice is based on several assessments, and application of the ALARA principle. Evaluation of plant inventories and operation, and experience from other fusion machines have lead to conclusion that the above limits are the lowest reasonably achievable. The limits, however stringent, to not present a burden to plant operations. A comparison of Ignitor and ITER risk-based curves is finally carried out.
