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.

Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

Carburization of high-temperature alloys has been frequently observed during exposure to dry high-temperature gas-cooled reactor (HTGR) helium compositions. Therefore, the influence of carburization on mechanical properties of alloys that may be used for HTGR high-temperature components has been studied. In creep rupture tests on high-temperature alloys for up to 20 000 h, the data in air and in various simulated HTGR heliums lie in the same scatterband irrespective of carburization that has been observed in the contaminated helium atmospheres. The dependence of room temperature tensile properties and the impact strength in the 20 to 800 °C range on the carburization level has been measured so that the maximum carbon level for a given room temperature ductility and impact strength could be specified. The results showed that the minimum room temperature elongation fell to below 5% when the carbon content exceeded 0.5 wt% for Incoloy-800H and 0.2 wt% for lnconel-617. At these carbon levels, the alloys have impact strengths (ISO V-notch specimens) of ∼50 J or above at temperatures in the 25 to 800°C range.
