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.
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.

Type One Energy wants to build a stellarator at retired coal plant
Type One Energy Group announced plans on February 21 to relocate its headquarters from Madison, Wis., to the Tennessee Valley Authority’s (TVA) Bull Run fossil plant in Clinton, Tenn., where it will build a stellarator fusion prototype machine. According to the company, the construction of the stellarator—called Infinity One—could begin in 2025, if necessary environmental reviews, partnership agreements, permits, and operating licenses are all in hand.

The Nuclear Regulatory Commission is undergoing rulemaking to develop 10 CFR Part 53. Part 53 provides a risk-informed, performance-based regulatory framework, with requirements scaled based on design features and safety margin. The current reactor licensing regulations (Parts 50 and 52) provide deterministic requirements that define the design capabilities required to achieve the desired margin. Any of these licensing pathways provide viable options for advanced nuclear reactors. Compared to Parts 50/52, the differences in Part 53 are dramatic. Part 53 provides frequency and consequence-oriented requirements compared to prescriptive requirements in Parts 50/52. Additionally, Part 53 is technology-inclusive compared to being optimized for a specific technology, has explicit consideration of defense-in-depth compared to operating experience, and includes expanded use of graded equipment compared to conservative assumptions and analyses. NRC staff is listening to all stakeholders regarding the proposed Part 53 rulemaking and has made changes in response to stakeholder feedback. This session will discuss the status of Part 53 and how it could affect stakeholders.
