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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

We examined the difference of the heating characteristic by the injection condition of the ECRH from the measurement of the soft X-rays representing the electron temperature. The line integrated intensity of soft X-ray (IsxL) in X-mode ECRH (the best absorption) increased to 5.8 times of that without ECRH and 3.4 times in O-mode (the worst absorption). The MCP signal ratio of the different absorbers (Pe2/Pe1.5) increased from 0.43 before ECRH to 0.56 during ECRH of X-mode and from 0.47 to 0.52 in O-mode. It is confirmed the electron heating by ECRH qualitatively in both cases. However the ion stored energy decreased in O-mode ECRH. This results show that it is important to maximize the first pass RF absorption at the resonance layer on axis for the efficient electron heating and avoidance of the confinement degradation of plasma.
