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.

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.”

Progress is given on the investigation of a low cost, scientifically attractive, and technologically feasible volumetric neutron source (VNS) based on the spherical torus (ST) concept. The ST-VNS has a major radius of 1.07 m, an aspect ratio of 1.4, and a plasma elongation 3. It can produce a neutron wall loading ultimately up to 5 MW/m2 averaged over the outboard test section when the fusion power reaches 380 MW. Initial operation of this device can be at a level of 1 MW/m2 or lower. Higher performance blanket components can be developed to raised the neutron wall loading. Using staged high wall loading operation scheme and optimistic availability projected for the VNS device, a neutron fluence of more than 30 MW-y/m2 can be expected to accumulate within 20 years of operation. Assessments of lifetime and reliability of fusion core components will thus be allowed in a power reactor relevant environment. A full-function testing of fusion core components may also become possible because of the high neutron wall loading capability. Integrated testing of tritium breeding in such a full scale power reactor relevant VNS device can be very useful to verify the self-sufficiency of fuel cycle in candidate power blanket concepts.
