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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The Fukushima Daiichi accident occurred on March 11, 2011. A seismic event and tsunami induced an extended station blackout plus loss of the ultimate heat sink. Three units progressed into a core melt severe accident. The accident occurred in the emergency operation procedure (EOP) domain. However, this situation was already beyond the scope of an EOP. The operator followed the EOP faithfully, and a core melt situation still occurred. An interesting topic is whether it is possible to avoid this type of accident. The purpose of this study is to survey the Fukushima accident progression with respect to the effect of the containment venting strategy for the Chinshan Nuclear Power Plant EOPs. Under the emergency situation, only a small reactor pressure vessel (RPV) injection system was available. This type of accident may be avoided by an early shift from the EOP to the severe accident guideline (SAG), switching from high-pressure injection to low-pressure injection while the reactor core isolation cooling system is available, gradually lowering the RPV pressure, and maximizing the injection flow rate. The plant responses and accident physical phenomena were simulated using MAAP5. The results show that the consequences of an uncovered core and core melt can be avoided by adopting the proper RPV depressurization and containment venting strategy.
