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 since 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. local time 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.”

This paper presents considerations on basic requirements of fuelling, plasma exhaust and wall conditioning in ITER-EDA. In ITER-EDA, typical machine parameters are 1.5 GW of a fusion power and 1000 sec of a DT burn duration. Fuelling system consists of gas- and pellet injection systems. Maximum DT fuelling rate is 100 Pam3/s (pellet) to 500 Pam3/s (gas). Impurity gas(e.g. Ne, Ar) will be also injected to control divertor radiation loss. In plasma exhaust, designed value of total neutral pressure at inlet of pumping duct is 0.1 Pa to 10 Pa. Total net pumping speed of cryogenic primary pumps is about 300 m3/sec. In maximum, 90% of the regenerated fuel gases (H, D, T) from the primary cryopump will be directly back into the plasma. In wall conditioning, glow discharge cleaning (GDC) and electron cyclotron resonance discharge cleaning (ECRDC) are considered.
