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.

A discrete neutron kinetics for periodically pulsed fast reactors is formulated in which the time behavior of the delayed neutron precursor concentrations is considered explicitly only just before and just after each power pulse. The power pulse is represented by a delta function and a general integration of the precursor equations between pulses is used. The difference equations obtained are well suited for use in digital simulation of pulsed reactors. An “inhour equation” for pulsed reactors is derived from the difference equations and is shown to reduce to the relation obtained from the period-averaged kinetics equations, if the deviation from pulsed criticality is small.
