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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

NRC Hanson's renomination clears Senate committee
Hanson
The U.S. Senate Environment and Public Works Committee voted 18–1 yesterday to advance the renomination of Christopher T. Hanson as a member of the Nuclear Regulatory Commission. Hanson has been a commissioner since 2020, and was named chair by President Biden in January 2021. The full U.S. Senate will consider Hanson’s nomination later this month.
Voices of support: “Chair Hanson is a dedicated public [servant] who has thoughtfully and . . . skillfully led the [NRC] during his tenure as its chair. Throughout his time on the[NRC], he has demonstrated his commitment to ensuring the safety and the security of our nation’s use of nuclear energy,” said EPW committee chair Tom Carper (D., Del.) before the vote.

A scoping study was performed to explore tritium breeding and energy-temperature splits in various blanket concepts for high-temperature process heat. Temperature limits for the lithium materials necessitate two blanket zones. One delivers heat at moderate temperatures (≾600°C) and breeds tritium. The other is a nonbreeding zone that produces heat at high temperatures. We find that a system where all blanket modules breed tritium delivers more high-temperature heat than one where only some of the blanket modules produce tritium. Of those considered, a design where the high-temperature zone is placed between two breeding zones produces the highest fraction of high-temperature heat. When liquid lithium, Li7Pb2 and Li2O tritium breeding materials are employed with two breeding zones, a tritium breeding ratio of 1.1 can be achieved while delivering 30 to 40% of the blanket heat at high temperature.
