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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Nuclear fuel cycle reimagined: Powering the next frontiers from nuclear waste
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.

A production route for 99mTc and 101Tc using the (γ,p) reaction was considered. For an electron beam with energy of 40 MeV and power of 10 kW, distributions of produced 99mTc and 101Tc were obtained. For the optimized target (0.5 g) configurations, values of 99mTc specific activities of 9.53 GBq/g (0.26 Ci/g) for a one-stage setup and of 1.77 GBq/g (0.049 Ci/g) for a two-stage setup were obtained. For 101Tc, the corresponding values were 6.51 GBq/g (0.18 Ci/g) and 1.24 GBq/g (0.033 Ci/g).
