Methods for Collection and Evaluation of Concrete Data within the Nuclear Industry

| 2024:1032 | Felix Kåhrström, Judith Hambraeus, Mårten Janz, Per Johannesson, Afry
This project has identified variations in the level of digitalization across the nuclear facilities as well as differences in data storage and analysis methods.

\u003Cp\u003EThe Swedish and Finnish nuclear facilities need methods to analyse data from measurements and visual inspection. Currently, data exist in several locations but is often stored in reports. An important first step is to establish an ETL process to extract, transform and load the data into a data repository to facilitate the analysis. Various statistical methods can then be used to analyse the data to make trends and predictions, such as regression analysis. To analyse future data from visual inspections and improve data collection, the recommendation is to use a software available on the market, which often includes 3D models and facilitates documentation through a tablet. Implementing BIM and 3D modelling could also be a viable solution.\u003C/p\u003E

    Shear Force Capacity of Existig Concrete Slabs, 2025:1102

    Shear force capacity in concrete slabs is crucial for structural integrity, especially in nuclear power plants where safety and reliability are paramount. In several cases low or sometimes insufficient shear force capacities have been observed in structural analyses of existing concrete slabs using modern codes. Understanding shear force capacity and how it has been treated in earlier codes helps ensure durability and safety, preventing structural failures.
