Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.”

The calculation accuracy of the newly developed 3D discrete ordinates code, Attila, is benchmarked by comparing its prediction to the measured data in two mockups bombarded by 14 MeV neutron source of the FNG facility located at Frascati, Italy. The results are also compared to those based on MCNP Monte Carlo code for the same measured reactions. The experimental mock-ups simulate parts of ITER in-vessel components, namely, the tungsten (W) mockup and the ITER shielding blanket. The first mockup was used to validate W data as a material for plasma facing component. A streaming path was introduced in the second configuration. The objective of this paper is to benchmark Attila code to determine its adequacy for fusion application. Another objective is to compare results based on two distinctive 3D calculation tools using the same nuclear data, FENDL2.1, and the same response function (IRDF-90) for measured data. The results of these comparisons are reported in this paper.
