Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

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.”

The Assembly and Maintenance (A&M) System is the complete set of personnel, equipment, and procedures required to successfully assembly and maintain the ITER components into a reactor capable of operation in the prescribed manner. It is composed of the complete collection of general and special purpose tools and their operating procedures, required for the assembly and maintenance of the ITER device. Included are the reactor specific auxiliary equipment (such has vacuum pumps and heating systems) directly coupled to the reactor and required for its operation. Also included are special facilities, including tools and fixtures, required for preassembly, inspection, disassembly, repair, or testing of components prior to delivery and final assembly. The A&M system operated within an envelope bounded by the plant confinement/containment system. It must have access to all reactor external and internal surface as required to perform its functions. Access to in-vessel components shall be primarily through the four designated maintenance ports located on the machine equatorial plane. Other ports, such as the top vertical port, can be used for maintenance; however, their use shall be limited to less frequent or unplanned operations such as the change-out of internal shielding or blankets, or recovery from an unforeseen event.
