Revisions to Design of Structures, Components, Equipment, and Systems Guidance for NRC Staff

The U.S. Nuclear Regulatory Commission (NRC) is issuing a final revision to two sections in Chapter 3, ``Design of Structures, Components, Equipment, and Systems,'' of NUREG-0800, ``Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition.'' The revisions to these Standard Review Plan (SRP) sections reflect no changes in staff position; rather they clarify the original intent of these SRP sections using plain language throughout in accordance with the NRC's Plain Writing Action Plan. Additionally, these revisions reflect operating experience, lessons learned, and updated guidance since the last revision, and address the applicability of regulatory treatment of non-safety systems where appropriate.
