Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Application is open for IAEA Marie Sklodowska-Curie Fellowship Program
The International Atomic Energy Agency has announced the opening of this year’s application process for its Marie Sklodowska-Curie Fellowship Program (MSCFP), which is designed to “inspire and encourage young women to pursue a career in the nuclear field, by providing highly motivated female students with scholarships for master’s programs and an opportunity to pursue an internship facilitated by the IAEA,” according to the program description.

The Thermal hydraulics, Aerosols and Iodine (ThAI) facility, located in Eschborn, Germany, is a 60-m3 steel test vessel designed to simulate operational and accident conditions in a nuclear containment structure. The ThAI facility provides experimental data used for validation of thermal-hydraulic codes. The test performed at this facility has been modeled using the GOTHIC 8.1(QA) software package for the purpose of validating both physical models and modeling techniques.
The test analyzed is from step 2 of the International Standard Problem 47 test performed at the ThAI facility. This test consisted of three injection ports for steam and helium to enter the vessel off-axis. The off-axis injection locations along with the compartmented geometry of the facility provide a complex coupling of physics that would be present in an accident transient inside the containment of a typical light water reactor. Key considerations of this analysis are stratification of the steam and helium, condensation deposition, and flow patterns within the vessel.
