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.

Study: New U.K. nuclear likely to be lower carbon source than solar or wind
A recent study of life cycle carbon emissions at the United Kingdom’s Hinkley Point C nuclear plant finds that the facility, now under construction in Somerset, England, is likely to produce less CO2 over its lifetime than either solar or wind power.
According to the 70-page analysis—prepared by environmental consultancy Ricardo Energy & Environment for NNB Generation Company HPC Limited, the holding company for the Hinkley Point project—lifetime emissions from Hinkley Point C are likely to be about 5.5g CO2e per kWh. That amount also holds for the proposed Sizewell C plant, the study concludes. (The two 1,630-MWe EPRs at Hinkley Point C are currently scheduled to begin commercial operation in 2026 and 2027.)

Quenching experiments were conducted to investigate the effect of deposition of SiC and graphene oxide (GO) nanoparticles on heat transfer during rapid cooling in vertical tubes. Temperature histories during quenching were measured for each test section to confirm the effect of the nanoparticle-coated layer on quenching performance. Boiling curves for each test were obtained by using the inverse heat transfer method. Quenching performance was enhanced ∼20% to 31% for nanoparticle-coated tubes compared to the bare tube. Scanning electron microscope images of the inner surfaces of the tubes following the experiments were acquired, and the contact angles were measured to observe the effect of surface structures and wettability on quenching performance. In the case of tubes coated with GO nanoparticles for 900 s, quenching performance and critical heat flux (CHF) were enhanced although the contact angle increased. To confirm the surface effect on the enhanced quenching performance and CHF of GO nanoparticle–coated tubes, FC-72 refrigerant was used as the working fluid of the quenching experiment to reduce the wettability effect on the heat transfer.
