**6.1. Modification design and procurement of equipment**

During modifications, replacements and reconstructions, design and procurement can be executed by complying with the seismic safety requirements corresponding to the seismic and safety classification. These processes are part of the configuration management and subject to authority approval. There is a database for seismic and safety SSCs. A procedure exists ensuring the adequacy of the design and procurement specifications.
