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.

Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

Nuclear fusion research promises to harvest the excess energy carried by energetic neutrons when Deuterium and Tritium hydrogen isotopes are fused together to form -particles. Pressure and density conditions needed for these fusion reactions ensure that these charged constituents, together with the free electrons, form a fully ionized plasma at temperatures of about 100 million Kelvin. Any contact with material walls would instantaneously cool the plasma and must be avoided. In the axisymmetric toroidal vessel of a tokamak, a hot plasma is confined primarily by magnetic Lorentz forces. Strong helical magnetic fields that trace out nested toroidal surfaces help to thermally insulate the plasma from the walls and support it against its own pressure gradient. To lowest order, a fluid model of the equilibrium considers only this force balance in the poloidal cross-section of the tokamak, as expressed analytically by the Grad-Shafranov equation.
