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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

We are studying the feasibility of using boron doping to refine the grain structure of sputter-deposited Be for NIF ignition capsule ablators. The goal is to improve the surface finish and homogeneity of these coatings. Films deposited on flat silicon substrates display a pronounced change in structure at a concentration of ∼11 at.% B. At lower levels of B, grain sizes of about 200 nm are observed. AFM images show the roughness of these films to be about 20 nm rms. At higher levels of B, the grains size drops to below 50 nm and the roughness decreases to less than 2.5 nm rms. Films deposited on capsules do not show the same behavior. In particular, at 15 at.% B, the capsule coatings have nodular structure with an rms roughness of greater than 50 nm. When viewed in cross section, however, no structure is seen with either the flat films or the capsule coatings. We believe that differences in substrate temperature may be largely responsible for the observed behavior.
