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.
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.

Advanced reactors: Now comes the hard part
Designing a reactor is complicated but building one may be harder. Even companies that have had lots of practice haven’t always done it well. And all the power reactors in service today were built by companies that had years of experience in other kinds of big steam-electric power plants. In contrast, some of the creative new designs now moving toward commercialization come from start-ups that have never built anything at all. How should they prepare?

Rayleigh-Taylor experiments have been designed for the OMEGA laser facility at the Laboratory for Laser Energetics (LLE) of the University of Rochester to explore perturbations during implosion of this ablator. For the experiment to be relevant, the beryllium copper flat used as the target must be similar in chemical makeup and morphology to the NIF ignition target. To visualize the perturbation growth, the flats were fabricated with sinusoidal perturbations on one side of a wavelength of 50 m and amplitude of 0.25 m. The flats were doped with more copper than required in the NIF ablator specification to increase the x-ray optical depth during burn through. These flats were successfully fabricated using a mold technique. This technique, as well as the characterization techniques used to verify the chemical makeup and thicknesses, will be described in this paper.
