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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

This study presents an investigation of critical heat flux (CHF) variation upon the use of candidate Accident Tolerant Fuel (ATF) cladding (FeCrAl alloy) compared to Inconel600, Zircaloy-4 and the 2006 CHF look-up table by conducting the flow boiling experiments under steady-state condition at an atmospheric pressure and at fixed inlet temperatures and a mass flux. To directly compare the CHF change during transient condition relevant to Reactivity Initiated Accident (RIA), experiments were done at the same thermodynamic quality and flow condition following the steady-state condition CHF results. An increased thermal safety margin of FeCrAl alloy compared to other tested alloys were identified as well as a disagreement between the Zircaloy-4 experimental CHF results and the 2006 CHF look-up table, which implies limitation of the current thermal-hydraulic codes for interpreting fuel design safety margin. To gain a better understanding on the implications of wettability on CHF, contact angle measurements were carried out on both fresh and oxide surfaces and the detailed morphology analysis was done by scanning electron microscope, which suggests a negligible impact of the wettability on the flow boiling CHF.
