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
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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Nuclear operation of HRE-2 began in December, 1957. In January, 1960, the reactor was shut down for repair and modifications of the core tank. During this two-year period, operation of HRE-2 went far toward attaining the original goals of the experiment. It was possible to operate continuously for periods of up to three months; with the exception of the core tank, the life of components exceeded expectations. The maintenance which was required was shown to be practicable. Continuous removal of neutron poisons during operation and excellent containment of radioactivity were demonstrated. The general corrosion rate proved to be moderate to low. Although the experience was generally good, at some operating conditions fuel solution instability was observed when the reactor was operated at power. Uranium which separated as a result of the solution instability sometimes caused reactivity excursions. Uranium deposits in the core led to hot spots and two holes were melted in the thin Zircaloy-2 tank which separated the core and the blanket. Core modifications were designed to alleviate the conditions which led to fuel instability, and future operation will test the effectiveness of the changes.
