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?

The mechanisms of radioactive corrosion product buildup on the stainless steel surface used for the primary cooling systems of boiling water reactors have been considered and the following conclusions obtained. 1. Ionic species are taken into a spinel structure on the surface and the deposition rate is expressed as a function of exposure time and temperature of contact water. 2. Crud is deposited on the oxide layers at a rate in proportion to the 0.82th power of the Reynolds number. Some ionic species are released from the crud on the oxide layers and are taken into a spinel structure as in item 1. Their contribution to the dose rate buildup is dominant at a dirty plant (which has a high iron content in the feedwater system). 3. The spinel structure grows at the boundary between the oxide layers and the base metal as a result of dry corrosion of stainless steel, which involves ionic species diffusing through the oxide layers. The mechanism is supported by data from destructive measurements of the reactor water cleanup piping at Tsuruga Nuclear Power Plant.
