Subject:
Definition of a Fire Protection Program (FPP) Change Is this interpretation of current guidance? Yes / No Proposed new guidance not in NEI 04-02? Yes / No Details:
NEI 04-02 guidance needing interpretation (include section, paragraph, and line numbers as applicable):
NEI 04-02 Sections 4.4 and 5.3 require revision to clarify what is considered a fire protection program-related change with respect to a Fire PRA.
Circumstances requiring guidance interpretation or new guidance:
Implementation of an NFPA 805 FPP change process requires that the plant have an acceptable fire PRA in order to use the risk acceptance criteria (Regulatory Guide 1.205 Section C.3.1).
Changes to the plants internal events PRA and therefore the Fire PRA occur for various reasons (e.g., model updates, etc). Not all these changes should be considered fire protection program changes subject to the NEI 04-02 change process. Clarification is required to delineate that changes to the Fire PRA should not be considered a FPP-related change.
Note: This FAQ was submitted as Revision 1 on October 26, 2006 (ML0631805444). NRC comments were provided on August 23, 2007 (ML072400021).

Note: Changes to the PRA model, which includes the documentation, data elements and associated logic, do not necessarily constitute a Fire Protection Program-related change.
Additionally, any plant equipment or procedures that are used in the fire PRA or the underlying Level I and Level II PRA, but are not specifically included as part of the nuclear safety capability assessment, are not considered Fire Protection Program-related. The PRA itself (data, logic, supporting documentation and analysis) is built to reflect the facility as designed and operated. Thus a change to the PRA itself would not be a change to the structures, systems, or components or plant procedures and is not a Fire Protection Program-related change.
