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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Hot dip aluminizing was tried on Indian reduced activation ferritic martensitic steel. This experiment was performed with aluminum (Al) melt, with three different silicon (Si) concentrations (3%, 5%, and 7%). Samples were dipped into the Al-Si melt, at 750°C for 30 s, which produced a hard and brittle Fe2Al5 intermetallic layer on the samples. These samples were subjected to two types of heat treatments: (I) 760°C for 30 h and (II) 980°C for 0.5 h, followed by 760°C for 1.5 h to convert the intermetallic layer into more ductile phases. The width of the Fe2Al5 layer was <10 μm for all the samples with different Si concentrations, and for the pure Al melt, it was ∼35 μm. For both the heat treatments, FeAl and α-Fe(Al) layers were observed. Out of the two heat treatments, heat treatment I gives thinner FeAl and α-Fe(Al) layers compared to heat treatment II. X-ray diffraction measurements confirmed the formation of an α-Al2O3 layer on the surface, for 3% and 5% Si concentrations for heat treatment I and for all Si concentrations for heat treatment II. The hardnesses of the Fe2Al5, FeAl, and α-Fe(Al) layers were found to be 972 to 1089 HV (hardness value)/0.01, 324 to 384 HV/0.01, and ∼200 HV/0.01, respectively.
