As a CANDU6 reactor has a high pressure primary cooling system and an independently cooled moderator system, the moderator in the calandria would act as a supplementary heat sink during a loss of coolant accident (LOCA) if the primary cooling and emergency coolant injection systems fail to remove the decay heat from the fuel. For the safety concern it is required to predict the 3-dimensional velocity and temperature distribution of moderator fluid to confirm the effectiveness of moderator heat sink. Korea Atomic Energy Research Institute (KAERI) is carrying out a scaled-down moderator test program to simulate the CANDU6 moderator circulation phenomena during steady state operation and accident conditions. This research program includes the construction of the Moderator Circulation Test (MCT) facility, production of the validation data for self-reliant CFD tools, and development of optical measurement system using the Particle Image Velocimetry (PIV). In the present work the PIV technique is used to measure the velocity distributions in the scaled moderator tank of MCT under iso-thermal test conditions. The preliminary PIV measurement data are obtained and compared with CFX code predictions.

Little is currently known about the mechanisms by which pathogenic variants of FGFR2 produce changes in the FGFR protein and influence the clinical presentation of affected individuals. We report on a patient with a de novo pathogenic variant of FGFR2 and a phenotype consistent with Jackson-Weiss syndrome who presented with delayed, rapidly progressive multisutural craniosynostosis and associated medical complications. Using 3-dimensional modeling of the FGFR protein, we provide evidence that this variant resulted in abnormal dimerization and constitutive activation of FGFR, leading to the Jackson-Weiss phenotype. Knowledge regarding the correlation between genotype and phenotype of persons with FGFR2-related craniosynostosis has the potential to allow for anticipation of medical complications, institution of early treatment, and improved clinical outcomes.
