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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

General Kenneth Nichols and the Manhattan Project
Nichols
The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.
As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

Nek5000 is an open-source, highly scalable, high-order, spectral-element-based computational fluid dynamics code. It combines the accuracy of spectral methods with the flexibility of the finite element method. It has been used for a wide range of applications in nuclear energy. It has the capabilities to perform DNS, LES, and unsteady RANS simulations using either an incompressible or low-Mach model. Its high-fidelity capability with the LES model has been well documented with consistent strong performance in international benchmarks. This workshop will guide users in downloading and compiling Nek5000 as well as setting up and running a few demonstration cases.
To participate, attendees must have access to a computer with a Unix based operating system and basic familiarity with using the terminal along with compatible FORTRAN 77 and C compilers installed with a working MPI wrapper. For details see here: https://nek5000.github.io/NekDoc/quickstart.html. Either ParaView (www.paraview.org) or VisIt is necessary for visualization of results. We strongly recommend that attendees are familiar with either tool and have one installed prior to the workshop.
Cost: $99
