Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

IAEA initiated safety concept of Defense-in Depth (DiD) for nuclear power plants (NPPs) has been promoted in all the nuclear developing countries around the world. Thus far, the authors of this paper have been developing various risk analysis methods and conducting the application studies to be applicable for any layers of DiD of NPPs. In this paper, a unified methodology of “integrated DiD risk analysis system” which is composed by three core systems, that is, (i) DiD risk state estimation and scenario generator, (ii)plant DiD risk monitor, and (iii)reliability monitor. Those three core systems will utilize many supportive toolkits for each layer of DiD to generate appropriate software system of either (i)offline analysis for designing and evaluation of a specific application, or (ii)online real-time processing for HIS (human system interface) for monitoring, diagnosis and procedure presentation. The basic idea of why, what and how to integrate and where to be used are overviewed prior to the software system development for individual purpose of usage either off-line or on-line.
