Explanation of September 30, 2004 changes in preliminary interim draft chapter
outline and aging management review (AMR) tables: Within the AMR tables, this update
process increases license renewal review efficiency by:
• Consolidating components (combining similar or equivalent components with
matching materials, environment and AMP into a single line-item),
• Increasing consistency between Material/Environment/Aging effects/aging
management Program (MEAP) combinations between systems (some existing
MEAPs had multiple definitions that, based on the aging effect, could be broadened
to envelope these into a singe MEAP),
• Correcting any inconsistencies in the 2001 edition of the GALL Report,
• Updating references to the appropriate aging management programs, and
• Incorporating line-item changes based on approved staff SER positions or interim
staff guidance.
The principal effect of this change is that the tables present the MEAP combinations at a
higher level, and the prior detail within a structure or component line item is no longer
explicitly presented. Consequently, the identifiers for subcomponents within a line item are
no longer presented in the tables. As a result, the introductory listings of these
subcomponents (originally in text preceding each table) have been deleted.
The following AMR tables contain a revised “Item” column and a new column titled “Link”,
which was not contained in the July 2001 revision. The “Item” number is a unique identifier
that is used for traceability and, as mentioned above, no longer presents the detailed
subcomponent identification. The link identifies the original item in the current version of the
GALL Report when applicable (items added to this list refer to bases statements not yet
available).

Proposed Draft NUREG-1801
By January 30, 2005, the NRC staff plans to issue a revised GALL Report (NUREG-1801)
and SRP-LR (NUREG-1800) for public comment. NRC anticipates re-numbering the lineitems to provide an improved unique identifier as part of the public comment document.
Also as part of the public comment process, the NRC will issue a NUREG documenting the
basis for the proposed changes to the GALL Report and the SRP-LR. This NUREG bases
document will be an aid for those reviewing the revised documents to understand what was
changed and the basis for the proposed changes.

Systems, Structures, and Components
This section addresses supports and anchorage for ASME piping systems and components. It is
subdivided into Class 1 (III.B1.1), Class 2 and 3 (III.B1.2), and Class MC (III.B1.3). Applicable
aging effects are identified and the aging management review is presented for each applicable
combination of support component and aging effect.
System Interfaces
Physical interfaces exist with the structure, system or component being supported and with the
building structural element to which the support is anchored. A primary function of supports is to
provide anchorage of the supported element for internal and external design basis events, so
that the supported element can perform its intended function.

Systems, Structures, and Components
This section addresses supports and anchorage for miscellaneous structures. Applicable aging
effects are identified and the aging management review is presented for each applicable
combination of support component and aging effect.
System Interfaces
Physical interfaces exist with the structure, system or component being supported and with the
building structural element to which the support is anchored. A primary function of supports is to
provide anchorage of the supported element for internal and external design basis events, so
that the supported element can perform its intended function.
