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.
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

NRC schedules webinars on Holtec’s proposed New Mexico storage site
The Nuclear Regulatory Commission has scheduled four webinars in late August and early September to present its draft environmental findings and receive comments on Holtec International’s proposed consolidated spent nuclear fuel storage facility in New Mexico. Webinars were previously held on June 23 and July 9.
As published in the August 13 Federal Register, the public comment webinars will be held on August 20 from 6–9 p.m., August 25 from 2–5 p.m., August 26 from 6–9 p.m., and September 2 from 11 a.m.–2 p.m. All times are Eastern. Information for the webinars is posted on the NRC’s Public Meetings webpage.

The rapid decay of magnetic flux during a plasma disruption induces voltages, currents, and Lorentz loadings in nearby electrically-conducting material. Present designs employ toroidal shells or shell segments near the plasma. These shells are divided into sectors for assembly and maintenance considerations, but may have toroidally-continuous conducting paths due to the need for vacuum boundaries. Voltages induced across sector gaps may initiate arcing and subsequent material damage. In addition, induced eddy currents in the shells can interact with the toroidal field and generate large net torques on a sector. A finite element model was used to estimate the induced sector gap voltages and net overturning moments following a 10 ms disruption. The number of shells, toroidal continuity, resistivity, and shell thicknesses were varied. Results are presented that show the effects of these changes on the sector gap voltages and induced loads.
