Seismic assessment is part of a range of seismic evaluation tasks applied to SSCs at the design and operational stages of plants life. Often based on a range of design codes, seismic assessment demonstrates structural integrity and stability by taking into account many aspects of the strain and effects due to earthquakes.
Seismic assessment calculates the capacity of SSCs in accordance with appropriate design codes and standards and compare the capacity against all loading demands. This will demonstrate the capability of the SSCs to perform their design safety functions against the defined earthquakes.
As part of structural integrity assessment capability, EASL carries out seismic assessment to demonstrate operability, integrity, and/or stability of structures, systems, and components (SSCs) to earthquakes. For safety-related nuclear SSCs, seismic assessment is often an essential part of nuclear safety case.
