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.

NRC restores expiration dates for renewed Turkey Point licenses
The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of the Turkey Point nuclear power plant's units 3 and 4 subsequent license renewals (SLR) to July 19, 2052, and April 10, 2053, respectively.

Particle depletion in an enclosure with turbulent natural convection was investigated using severe accident code MELCOR 2.1. A model of the experimental DIANA facility was created and the results of the simulation were compared against the experimental and LES data from earlier work. Three particle sizes 0.5 ?m, 1.0 ?m and 2.5 ?m were used in the study. The temperature difference between the vertical isothermal walls of the enclosure was varied between 40 K, 20 K and 10 K. The MELCOR model reproduced the stratified temperature field and the encircling natural convective flow in the cavity qualitatively. The deposition rate was well matched between the MELCOR and experimental data, but further analysis indicated that the thermophoresis was overestimated in the MELCOR modeling, thus compensating for the turbulent deposition, which was not considered in this MELCOR simulation work.
