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.

Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

In a series of experiments, the dosimetry of OBT in the mice supplied with THO or OBT directly or indirectly from their mothers was studied. In the offspring mice nursed by mother mice supplied with THO as drinking water, the largest contribution of OBT to the total accumulated dose was found in the brain. The percent contribution of OBT to the total dose distributed between 17 and 42% among various soft tissues. The OBT localization to cell nuclei increases the microscopic dose to cell nuclei by a factor of 3 – 6 in the case of DNA-bound tritium in comparison with the dose estimated from the tissue-averaged tritium concentration. The tritium localization is of less importance in the case of protein-bound tritium. The blood level tritium was found to be useful and convenient for OBT dosimetry in a practical case of radiation protection of humans after acute and chronic intake of tritium. A new technique was developed to isolate mouse red bone marrow from tibia. A model experiment using mice has shown that the dose to red bone marrow in the case of oral THO intake was lower than the dose estimated for the blood pool.
