The Office of New Reactors and Office of Nuclear Reactor Regulation are revising these sections from the current versions. In respect of these revisions, details of specific changes are included in the end of each of the revised sections themselves and are shown in the description of changes.

The changes to this Standard Review Plan (SRP) Chapter reflect current staff review methods and practices based on lessons learned from NRC reviews of design certification and combined license applications completed since the last revision of this chapter. Changes include: (1) Enhancements to guidance to the staff for evaluating the acceptability of the seismic and civil structural design and analysis issues, (2) updates to review interfaces to improve the efficiency and consistency of staff reviews and (3) updates to references covered in SRP Chapter 3.
