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 v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

In the presence of high gamma fields (l(105 to 107 R/h), the neutron sensitivity of a fission counter is drastically reduced because of gamma pulse pileup in the counter and in its associated preamplifier, thereby limiting the effective application of measurement techniques such as reactor neutron noise analysis in situations where gamma intensities of ≥l(106 R/h are encountered. To overcome this limitation a detector-preamplifier system with current-mode signal processing was developed. The detector, which contains electrode plates coated with enriched uranium, has a neutron sensitivity of 0.56 count/(sec nv). It is connected with 40 ft of cable to a low-noise preamplifier. This detector is designed to reduce alpha pulse pileup and gamma sensitivity and to have a fast charge-collection time. Current-mode signal processing required the development of a lownoise preamplifier. Measurements made with the system in gamma fields of 5 * 106 and 1 * 107 R/h showed a neutronsensitivity loss of 17 and 34%, respectively.
