Compilation of Concrete Test Data from The Nuclear Industry

| 2021:761 | Nick Zaraei, Peter Lundqvist
In this project an effort has been made to collect and compile results from various concrete testing performed at the nuclear power plants Ringhals, Oskarshamn and Forsmark in Sweden and Olkiluoto in Finland. In total results from 215 tests have been compiled performed during different time periods from the construction phase until recently. Approximately half of the compiled data regards tests for determining the compressive strength of the concrete and analyzing the chlorides contents in the concrete. Other types of tests are e.g. determination of carbonation depths, water penetration depth and analysis of thin sections.

The majority of the test data has not been evaluated in the original reports, therefore only results directly from the tests have been compiled. As a consequence the data cannot be used directly in theoretical analyses. Example of an evaluation method is the standardized procedure for determining the characteristic strength and concrete strength class.

    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.
