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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Radioactive iodine gas is a problematic species in multiple nuclear energy–related applications. Therefore, it is highly desirable to develop an adsorbent that has a high capacity for iodine. In this investigation, the iodine adsorption capacity of high-purity magnesium oxide was investigated as a function of the calcination conditions. Differences in the magnesia substrates were characterized by scanning electron microscopy and X-ray diffraction, and the iodine adsorption capacity was determined using thermogravimetric analysis. The results indicate that the calcination temperature and time have a significant impact on the adsorption capacity, with longer times and higher temperatures having a negative impact. However, under the optimal calcination conditions identified in this study (550°C for 20 min), the high-purity magnesia was found to have an adsorption capacity >300 mg of iodine per gram of sorbent. This suggests that magnesia holds promise for nuclear applications where iodine gas adsorption would be beneficial.
