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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

As future U.S. National Aeronautics and Space Administration (NASA) missions aim for destinations farther out into the solar system, space nuclear propulsion (SNP), and in particular nuclear thermal propulsion (NTP), is the only feasible near-term technology able to provide specific impulses of 900 s or greater and thrust in the range of tens of thousands of pounds. To maximize the success of the SNP program as a whole, a Fuel and Moderator Development Plan (FMDP) was created to mature mission critical technology, such as the reactor fuel form and moderator material. This technical note details the conceptual testing reference design that provides the basis for the FMDP for future design and testing activities to meet NASA’s goals.
Through this work BWX Technologies, Inc. and its subsidiaries, referred to as BWXT, continue to be an integral part of government space nuclear programs and has historically been a part of major design, manufacturing, and testing developments. As an example, during the 1990s BWXT supported fuel development for the Space NTP (SNTP) program, an advanced technology development effort aimed at providing the nation with a new and dramatically higher performing rocket engine that would more than double the performance of the best conventional chemical rocket engines. Since 2017, BWXT has been participating in the NASA SNP program for the low-enrichment uranium NTP rocket engine as part of its Game Changing Development feasibility conceptual design program and now more recently Technology Demonstration Mission.
