South Korean research team evaluates pipe rupture risk in nuclear power plants using probabilistic analysis

South Korean research team evaluates pipe rupture risk in nuclear power plants using probabilistic analysis

Researchers from Seoul National University of Science and Technology in South Korea have recently proposed a sensitivity analysis method based on probabilistic fracture mechanics to evaluate the rupture frequency of main coolant piping systems in nuclear power plants. This method can analyze the impact of uncertainties and modeling assumptions on prediction results, helping engineers distinguish extremely low-probability events from relatively more likely failure scenarios. In nuclear power plants, the main coolant piping system plays a critical role in maintaining structural integrity under normal reactor operating conditions. A pipe rupture could trigger a loss-of-coolant accident, and therefore this system has long been included in the key scope of nuclear power plant safety design and assessment.

German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells

German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells

A team from the Helmholtz-Zentrum Berlin (HZB) in Germany used the BESSY II synchrotron radiation facility to conduct nanoscale analysis of perovskite-silicon tandem solar cells fabricated by evaporation methods, and proposed a new approach to improve the quality of perovskite thin films. The study shows that introducing a thin cesium chloride (CsCl) seed layer between the two sub-cells promotes uniform growth of the perovskite layer while reducing undesirable lead iodide deposition at the interface. The research demonstrates that the cesium chloride seed layer improves the growth of the evaporated perovskite layer and reduces the formation of lead iodide. Scanning electron microscopy images show that the perovskite layer grown without a seed layer (left image) consists of extremely fine crystallites...
