NSUF rolls out new tool for materials researchers

To get a job done, you need the right tool. Researchers now have one that will make their job easier—the Radioactivity and Damage (RAD) Calculator from the Department of Energy’s Nuclear Science User Facilities.

Most experiments conducted through the NSUF have the same underlying goal: quantifying irradiation effects on nuclear fuels and materials. Rather than doing a back-of-the-envelope calculation or a costly in-depth analysis with a nuclear engineer, users now have the flexibility to rapidly change experimental design parameters—such as selecting the reactor to be used, the sample location within the reactor, displacements per atom desired, and the time frame—and see which NSUF reactor can produce the desired result, all within seconds.

When users input their material composition, they will be able to choose among several NSUF reactors to accomplish their research. goals Graphic: NSUF)

The RAD Calculator is free to all to use. Users can access the RAD Calculator by logging into their NSUF account (or by first creating an account) and then, from the left navigation menu, selecting Resources and then RAD Calculator.

The NSUF headquarters is located at the Center for Advanced Energy Studies in Idaho Falls, Idaho. NSUF has 50 user facilities at 21 partner institutions around the United States.

To learn more about the NSUF and how to get access to its neutron, ion, and gamma irradiation, post-irradiation examination, beamline, and high-performance computing capabilities, go to nsuf.inl.gov.
