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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.
Educator Training
August 24, 2023|5:00–6:00PM (6:00–7:00PM EDT)
Available to All Users
A carbon-free energy future will depend on using all clean energy sources available. Students recognize the benefits of nuclear, solar, wind, and other clean sources, but not the challenge of integrating them to produce reliable and affordable electricity. In this installment of our Educator Training series, Shannon Bragg-Sitton, Director of the Integrated Energy and Storage Systems Division at Idaho National Laboratory, presented Department of Energy research about optimizing energy sources through integrated systems. A Q&A session followed her presentation.

Biographies
Shannon Bragg-Sitton
Shannon Bragg-Sitton is an internationally recognized pioneer in the innovative application of nuclear energy alongside other clean energy generators, seeking to maximize energy utilization, generator profitability, and grid reliability and resilience through systems integration.
Shannon is the director of the Integrated Energy & Storage Systems Division in the Energy & Environment Science & Technology Directorate at Idaho National Laboratory, which includes Power and Energy Systems, Energy Storage and Electric Transportation, and Hydrogen and Electrochemistry departments. She also serves as the National Technical Director for the DOE (Department of Energy) Office of Nuclear Energy Integrated Energy Systems (IES) program (http://ies.inl.gov), which has developed novel modeling and simulation tools for technical and economic assessment of multi-input, multi-output IES and supporting experimental capabilities. Dr. Bragg-Sitton is also the Chair of the recently established Gen-IV International Forum (GIF) interim Task Force (iTF) on Non-electric Applications of Nuclear Heat (NEaNH)
Eric Loewen
Eric Loewen is the Chief Engineer and Manager of the Chief Engineer’s Office at GE Hitachi Nuclear Energy, where he is responsible for leading the office in supporting new product and technology development, managing technical and enterprise risk, and mentoring and developing technical talent.
Eric graduated from Western State College with a B.A. in chemistry and mathematics, earned a commission in the U.S. Navy, and subsequently attended Navy Nuclear Power School and the Nuclear Prototype. After his active Navy service, he earned his M.S. and Ph.D. in Nuclear Engineering and Engineering Physics from the University of Wisconsin-Madison.
Eric worked in private industry prior to joining Idaho National Laboratory (INL) as a systems integration manager and interim department manager. Currently, he is chief consulting engineer at GE Hitachi Nuclear Energy (GEH) in Wilmington, N.C., where he leads GEH activities to deploy the sodium-cooled advanced reactor PRISM that can recycle used nuclear fuel from the current fleet of water-cooled reactors, as well as fission and eliminate weapons-grade material.
His U.S. Navy leadership roles included: Naval Prototype Nuclear Reactor School Instructor; B-2 Division Officer, Nuclear Quality Officer, Engineering Officer of the Watch, Surface Warfare Officer of the Deck aboard the USS LONG BEACH (CGN-9); and Commanding Officer of two Naval Reserve maintenance support units.
During his career, Eric received many honors and awards including Molten Metal, Inc. Technology Star Award (1995); ANS Public Communication Award (2003); DOE Outstanding Mentor Award (2003); GEH CEO Award (2012); and GE Regulatory Excellence Award (2010). He is also a Kissimmee Iron Man triathlete.
This webinar is presented by ANS in partnership with the Department of Energy, Office of Nuclear Energy.
