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.

As a result of the effect of residual gamma radiation on neutron detectors in shutdown reactors, the precision of subcriticality measurements by noise analysis is degraded. An equation for this gamma degradation effect was developed for application to fast reactors. The gamma degradation factor D and the detection efficiency Wn were evaluated for 10B, 3He, and 235U detectors for application in the Fast Flux Test Facility (FFTF), and it was concluded that the 235U, the least sensitive of the three detectors, is the best choice. The 235U detector is 40 times less efficient than the 3He detector, but it should experience only a slight degradation in the FFTF. By contrast, degradation factors varying between 100 and a few thousand are anticipated for the 3He detector through the shutdotvn range of -1 to -10 dollars. Furthermore, D is unity up to 106 R/h and is independent of p for the fission chamber when used as a counter.
