How are plant modifications approved by the fdgh?

For plant modifications that affect nuclear safety, the final design is approved by the FDGH. For plant modifications that do NOT affect nuclear safety, design approval is performed by the independent technical reviewer. After design approval, changes to the final design must be processed per NP 7.2.3.
