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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Findings of the ANS Executive Order Expert Advisory Group
On May 23, President Donald Trump signed four Executive Orders (EOs) designed to “usher in a nuclear energy renaissance” by building on federal policies and programs and directing efficiencies in the licensing, siting, development, and deployment of advanced reactor technologies.
In order to evaluate the specific proposals contained in the EOs, a group of experts was convened from various sectors of the U.S. nuclear technology enterprise, under the auspices of the ANS External Affairs Committee, to compare the EOs against existing ANS board-approved Position Statements and to offer constructive input for subsequent implementation by the Trump administration.
The group’s findings and feedback, which were delivered by ANS CEO Craig Piercy to ANS President Lisa Marshall and the Board of Directors, are listed below, grouped by individual EO.
Workshop
Thursday, April 8, 2021|11:45AM–1:00PM EDT
Session Chair:
Benjamin W. Beeler

Nuclear materials research encompasses fuel, cladding, gap bond, coolant, reactor pressure vessels, divertor, blankets and all other material systems of interest in fission and fusion reactor systems. A number of primary technological challenges facing the nuclear industry are all materials-based, such as extending to longer lifetimes, qualifying new fuel types for advanced reactors, and developing next generation reactor designs. This workshop will introduce participants to the field of computational nuclear materials science, with an overview of atomistic, mesoscale and fuel performance simulation methodologies. Participants will get hands-on training in molecular dynamics simulations on sodium cooled fast reactor metallic nuclear fuel systems utilizing the LAMMPS software package. LAMMPS is a state-of-the-art open source massively parallel molecular dynamics simulation code, that can be executed on a laptop. No prior computational experience is required, only an interest in nuclear materials research and a laptop is needed. Prior to participating in this workshop, please download the files named "InputFiles.zip" here. The extracted files will be used during the workshop in the interactive portion of the session.
