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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Bench scale methane cracking tests have been completed using a stack of ten SAES® St909 pellets. Baseline test conditions were five percent methane in helium at ten seem, 101 kPa (760 torr), and 700°C. Changes from baseline conditions varied temperature, pressure, flow rate, and carrier gas composition to include hydrogen and nitrogen. Methane cracking efficiency (ɛM) decreased with decreasing temperature and pressure. Faster gas feed rates decreased ɛM, but cracked more methane. Introducing hydrogen, nitrogen, or ammonia into the feed gas reduced ɛM, but ammonia was still cracked at high efficiencies. ɛM was further decreased when both nitrogen and hydrogen were in the carrier gas compared to using a carrier of only nitrogen or hydrogen.
