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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

A mathematical model for mass flow in a transmutation system has been established for a chain of two transuranic (TRU) radionuclides. The nonrecursive solutions for the fractions of the two TRU radionuclides in the transmuter core before and after the irradiation in the i'th cycle have been obtained by the similarity transformation. With the nonrecursive analytical solutions, the TRU reduction ratio has been formulated as a performance measure for the system. The stability of the system has been defined in terms of the moduli of the eigenvalues of the system. The conditions for a stable system and for a system to reach a quasi-steady state with fewer cycles have been shown in terms of the system parameters. A large value of the nondimensionalized destruction coefficient d is beneficial for effective waste reduction because (a) the system reaches a quasi-steady state faster; (b) the TRU mass in the waste can be reduced more effectively; and (c) the precursor effect becomes negligible, and each radionuclide can be approximately treated as a single radionuclide without precursors.
