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.

The major difficulties encountered in controlling the steam generator water level swell and shrinkage are analyzed. A mathematical model based on the amount of steam generated by depres-surization during the periodic steam dump is used to predict the level changes. When the existing proportional integral controller is applied to the negative of these predicted level changes and the output is added to the controller output for the normal level error, it is found that the water level does not go down below the lower limit or up beyond the higher limit. This control algorithm is tested on a model steam generator, and the results show it is capable of handling the difficulties in the control of the level swell and shrinkage.
