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 VENUS-F facility of the GUINEVERE project must satisfy the nuclear safety criteria required by the licensing regulations of the Belgian authority. For this reason, radiation shielding analyses were performed at Forschungszentrum Karlsruhe (FZK) in the course of nuclear safety assessments in support of the GUINEVERE project. The Monte Carlo (MC) MCNP5 model was developed in accordance with the current design of the VENUS-F fast lead reactor. The reactor was assumed to operate on 500-W fission power, which is called zero power, with accelerator-driven system (ADS)-related experimental aims. The MC variance reduction techniques, such as particle splitting, Russian roulette, weight windows, and point detectors, were applied. To speed up the MCNP calculations, the advantages of message-passing interface parallel computations on FZK's CampusGrid Linux Cluster were employed. The MCNP track-length estimations, point detectors, and the mesh tally superimposed over the GUINVERE geometry were used in dose rate calculations. The neutron and photon maps of dose equivalent rate were produced in places of possible personnel access inside the reactor control room and on the accelerator room's floor. To obtain the dose equivalent, the neutron and photon fluences were converted by means of ICRP-77 and ANSI/ANS-6.1.1-1977 conversion factors, respectively. The contributions of the D-D and D-T fusion neutron sources to the dose rate fields were estimated. Activation analyses of the lead core and building materials were performed by the FISPACT-2005 inventory code with the EAF-2005 library to manage the radioactive materials after the series of ADS experiments in the GUINEVERE project. The activity density and shutdown contact dose rate have been calculated. The effect of the impurities in lead on its radioactivity after the VENUS-F campaign was examined.
