NUCLEAR REGULATORY COMMISSION
[NRC-2013-0068]
Aging Management of Internal Surfaces, Fire Water Systems,
Atmospheric Storage Tanks, and Corrosion Under Insulation
AGENCY: Nuclear Regulatory Commission.
ACTION: Interim staff guidance; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing the
final License Renewal Interim Staff Guidance (LR-ISG), LR-ISG-2012-02,
``Aging Management of Internal Surfaces, Fire Water Systems,
Atmospheric Storage Tanks, and Corrosion Under Insulation.'' This LR-
ISG provides changes to NRC staff-recommended aging management programs
(AMPs), aging management review (AMR) items, and definitions in NUREG-
1801, Revision 2, ``Generic Aging Lessons Learned (GALL) Report,'' and
the NRC staff's AMP Final Safety Analysis Report Supplement program
descriptions, acceptance criteria for AMR items requiring further
review, review procedure for AMR items requiring further review, and
AMR items contained in NUREG-1800, Revision 2, ``Standard Review Plan
for Review of License Renewal Applications for Nuclear Power Plants''
(SRP-LR). These changes address new recommendations related to internal
surface aging effects, fire water systems, atmospheric storage tanks,
and corrosion under insulation.

SUPPLEMENTARY INFORMATION:
Background
The NRC issues LR-ISGs to communicate insights and lessons learned
and to address emergent issues not covered in license renewal guidance
documents, such as the GALL Report and SRP-LR. In this way, the NRC
staff and stakeholders may use the guidance in an LR-ISG document
before it is incorporated into a formal license renewal guidance
document revision. The NRC staff issues LR-ISGs in accordance with the
LR-ISG Process, Revision 2 (ADAMS Accession No. ML100920158), for which
a notice of availability was published in the Federal Register on June
22, 2010 (75 FR 35510).
The NRC staff has developed LR-ISG-2012-02 to address: (a)
Recurring internal corrosion, (b) a representative minimum sample size
for periodic inspections in the GALL Report AMP XI.M38, ``Inspection of
Internal Surfaces in Miscellaneous Piping and Ducting Components,'' (c)
flow blockage of water-based fire protection system piping, (d)
revisions to the scope and inspection recommendations of the GALL
Report AMP XI.M29, ``Aboveground Metallic Tanks,'' (e) corrosion under
insulation, (f) external volumetric examination of internal piping
surfaces of underground piping, (g) specific guidance for use of the
pressurization option for inspecting elastomers in the GALL Report AMP
XI.M38, and (h) key miscellaneous changes to the GALL Report and SRP-
LR.
On April 12, 2013, (78 FR 21980) the NRC requested public comments
on draft LR-ISG-2012-02 (ADAMS Accession No. ML12291A920). On May 23,
2013, the NRC conducted a public meeting to discuss draft LR-ISG-2012-
02. A meeting summary was published on June 20, 2013 (ADAMS Accession
No. ML13149A401).
The NRC received comments from the Nuclear Energy Institute by
letter dated June 14, 2013 (ADAMS Accession No. ML13168A397). No other
comments were submitted. The NRC considered these comments in
developing the final LR-ISG. Detailed responses to the comments can be
found in Appendix I of the final LR-ISG.
The final LR-ISG-2012-02 is approved for NRC staff and stakeholder
use and will be incorporated into NRC's next formal license renewal
guidance document revision.
Backfitting and Issue Finality
Issuance of this final LR-ISG does not constitute backfitting as
defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise
inconsistent with the issue finality provisions in 10 CFR part 52,
``Licenses, Certifications, and Approvals for Nuclear Power Plants.''
As discussed in the ``Backfitting Discussion'' section of the final LR-
ISG-2012-02, the LR-ISG is directed to holders of operating licenses or
combined licenses who are currently in the license renewal process. The
LR-ISG is not directed to holders of operating licenses or combined
licenses until they apply for license renewal. The LR-ISG is also not
directed to licensees who already hold renewed operating or combined
licenses.
Dated at Rockville, Maryland, this 14th day of November, 2013.
For the Nuclear Regulatory Commission.
Melanie A. Galloway,
Deputy Director, Division of License Renewal, Office of Nuclear Reactor
Regulation.
