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.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

The design of many of the process systems at the Savannah River Site (SRS) Tritium Facilities were developed at the Savannah River National Laboratory (SRNL) in the 1980’s and early 1990’s for Cold War production requirements. Most of the process systems developed used cold (non-radioactive) test systems to reduce the cost of developing pilot and full-scale test systems. The metal hydride (MH) based process technologies developed for the Replacement Tritium Facility (RTF) allowed tritium process equipment to be confined in tritium stripped glovebox systems which greatly reduced tritium emissions to the public. Facility start-up in 1994 was considered state-of-the art technology for the world’s largest metal hydride based tritium process facility. The end of the Cold War reduced production requirements, but increased maintenance is needed for the 20 year old process systems. The Hydrogen Processing Development System (HPDS) is a new, non-radiological R&D system to be built for testing and demonstrating improved process systems for SRS Tritium Facilities. Experience gained from facility operations and new concepts from fusion fuel cycle development programs will be used to develop improved processes and restore base capabilities of the SRS Tritium Facilities. The HPDS will be designed to test systems such as a Revised Unloading Purification System (RUPS), an optimized advanced storage and isotope separation (OASIS) System, a Reduced Area Confinement and WAter Processing (RACWAP) System, and some components of a separate breeding and extraction program. New processes would retain the desirable features of the current/existing technologies while creating “right-sized” and flexible advanced or hybrid system to meet current and future tritium processing needs. Testing in the HPDS will reduce the cost and risk of deploying new technologies into the SRS tritium production process.
