Abstract: In nuclear power plants post-installed fastenings are often used. A decisive criteria for the use of fastenings in safety critical applications is the proper functioning of fasteners under special conditions such as impact loading and earthquake excitations and cracks in concrete with a width superior or equal to 0.5 mm due to earthquake loadings.
Such special conditions are not covered by Technical Approvals according to [1].
Therefore, in Germany a guideline for the assessment of fasteners in nuclear power plants has been published [3]. This guideline is valid for undercut anchors with an embedment depth hef superior or equal to 80 mm, which are approved according to [1].
In this paper the concept of the guideline is explained. Details of the required suitability tests and the tests to determine admissible service conditions are given. Furthermore, results of tests with different types and sizes of undercut anchors are shown.
