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.
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

The development of commercial fusion power production using deuterium and tritium has been ongoing worldwide for decades and the European version of DEMO will undergo conceptual design between 2021 and 2027. Among the different ways to provide electrical power, nuclear fusion will be publicly accepted if the environmental impact is at tolerable levels. The auxiliary power requirements of fusion power reactors will need to be optimized, and heat will need to be efficiently converted to electrical power through the usage of high-temperature steam. On the other hand, heat might need to be intermittently stored to account for pulsed plasma operation, on the expense of the temperature level available for steam generation. Tritium is highly mobile and its management as far as containment and confinement are concerned becomes more difficult with the increasing temperatures of the structural materials; any effluents and releases should be kept to an absolute minimum. Therefore, tritium containment and confinement equipment and procedures need to be well integrated into the design and into the operation of fusion power reactors.
This paper focuses on the topics of the main tritium technologies under development in the EU DEMO Breeding Blanket Program, covering especially tritium breeding and extraction technologies. In addition, the identification of the main tritium sources as far as permeation and escape into the environment are concerned and the main barriers for the mitigation of tritium release into the environment are introduced.
