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.

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.

Suspensions of UO2 in NaK alloy are being studied as possible reactor fuels. Two loops have so far been constructed of one-half inch stainless steel tubing with a test volume of approximately 150 cc. The Mark I loop was operated for 400 hours between 450 and 600°C, while circulating a slurry of 4.3 volume % UO2 (36.0 weight per cent). The radioactive monitor indicated that the slurry was uniformly suspended at a flow rate of 2 ft/sec. It was found that above 500°C the UO2 dropped out of suspension, but was immediately resuspended when the temperature dropped below the critical value of 500°C. The effect was reversible and could not be eliminated even at the fastest flows. The Mark II loop incorporated a density measuring device in order to correlate the radioactivity monitor with the density of the slurry. It was found, as previously suspected, that when the counts reached maximum value the density also was a maximum, at the calculated value. One gram of powdered uranium metal added to the loop with the UO2 completely eliminated the settling above 500°C observed in the Mark I loop. There was no evidence for corrosion or erosion of the loop, and the particle size of UO2 was practically unchanged after operation at the high temperature. The UO2 could be resuspended immediately after prolonged settling.
