The NRC staff and stakeholders use LR–ISGs until their guidance is incorporated into a formal license renewal guidance document revision. The NRC staff developed draft LR– ISG–2009–01, ‘‘Staff Guidance Regarding Plant-Specific Aging Management Review and Aging Management Program for the NeutronAbsorber Material in the Spent Fuel Pool Associated with License Renewal Applications,’’ in light of recent operating experience concerning instances of degradation and deformation of neutron-absorbing materials in the spent fuel pools of nuclear power plants. Primarily, the draft LR–ISG proposed guidance for managing the potential loss of material and loss of neutron-absorbing capability aging effects for spent fuel pool neutronabsorbing materials other than Boraflex. A proposed aging management program was included in the draft LR–ISG to address these aging effects during the period of extended operation, as one approach acceptable to the NRC staff for meeting the requirements of 10 CFR part 54. On December 1, 2009, the NRC requested public comments on the draft LR–ISG–2009–01 in the Federal Register (74 FR 62829). The public comment period ended on December 31, 2009. By letters dated December 17, 2009 (ML093570197), and December 28, 2009 (ML100060388), the NRC received comments from two nuclear power plant licensees, Southern Nuclear Operating Company, Inc., and Exelon Generation Company, LLC, respectively. The NRC also received comments from the Nuclear Energy Institute, an industry group, by letter dated December 31, 2009 (ML100060387). After the comment period closed, the NRC received additional comments from the Nuclear Energy Institute in an e-mail dated January 6, 2010 (ML100280648). No other comments were received. The NRC staff considered all the comments in developing the final LR–ISG–2009–01, as discussed in the PO 00000 Frm 00158 Fmt 4703 Sfmt 4703 23821 ‘‘Comments and Responses’’ section of this notice. Final Action By this action, the NRC is making the final LR–ISG–2009–01 available. The NRC staff approves of the LR–ISG for NRC staff and stakeholder use. The NRC staff will also incorporate the approved LR–ISG into the next revision of the GALL Report and the SRP–LR. The final LR–ISG revises the staff’s aging management recommendations concerning spent fuel pool neutronabsorbing materials other than Boraflex, which are currently described in the GALL Report and SRP–LR. Specifically, the LR–ISG provides a program for managing the effects of aging on these spent fuel pool neutron-absorbing materials, whereas before, a plantspecific program was recommended. In addition, the corresponding aging management review line items in both documents are clarified and reference the recommended program instead of recommending further evaluation. The final LR–ISG also includes corresponding revisions to the SRP–LR for the staff’s review procedures and acceptance criteria concerning these spent fuel pool components and materials. The title of the LR–ISG has been changed from the draft title, ‘‘Staff Guidance Regarding Plant-Specific Aging Management Review and Aging Management Program for the NeutronAbsorber Material in the Spent Fuel Pool Associated with License Renewal Applications,’’ to the final, ‘‘Aging Management of Spent Fuel Pool Neutron-Absorbing Materials other than Boraflex,’’ to clarify that the LR–ISG provides guidance concerning generic, not plant-specific, aging management recommendations. Comments and Responses The comment providers, in general, recommended clarifications to the draft LR–ISG. The NRC staff included these clarifications in the final LR–ISG as appropriate. One comment indicated that the aging management program in GALL Report, Volume 2, Section XI.M2, ‘‘Water Chemistry,’’ should be credited to manage the loss of material aging effect. Another comment requested the NRC staff to provide the technical justification for the testing frequency in the proposed aging management program. Based on its technical evaluations, the NRC staff did not make substantive revisions to the LR–ISG in response to these two comments. Detailed NRC staff responses to all comments are in an appendix to the final LR–ISG document.

SUPPLEMENTARY INFORMATION: 

Background

    The NRC issues LR-ISGs to communicate insights and lessons learned 
and to address emergent issues that are not addressed in the guidance 
documents published to facilitate implementation of 10 CFR part 54. The 
NRC staff and stakeholders use LR-ISGs until their guidance is 
incorporated into a formal license renewal guidance document revision.
    The NRC staff developed draft LR-ISG-2009-01, ``Staff Guidance 
Regarding Plant-Specific Aging Management Review and Aging Management 
Program for the Neutron-Absorber Material in the Spent Fuel Pool 
Associated with License Renewal Applications,'' in light of recent 
operating experience concerning instances of degradation and 
deformation of neutron-absorbing materials in the spent fuel pools of 
nuclear power plants. Primarily, the draft LR-ISG proposed guidance for 
managing the potential loss of material and loss of neutron-absorbing 
capability aging effects for spent fuel pool neutron-absorbing 
materials other than Boraflex. A proposed aging management program was 
included in the draft LR-ISG to address these aging effects during the 
period of extended operation, as one approach acceptable to the NRC 
staff for meeting the requirements of 10 CFR part 54.
    On December 1, 2009, the NRC requested public comments on the draft 
LR-ISG-2009-01 in the Federal Register (74 FR 62829). The public 
comment period ended on December 31, 2009. By letters dated December 
17, 2009 (ML093570197), and December 28, 2009 (ML100060388), the NRC 
received comments from two nuclear power plant licensees, Southern 
Nuclear Operating Company, Inc., and Exelon Generation Company, LLC, 
respectively. The NRC also received comments from the Nuclear Energy 
Institute, an industry group, by letter dated December 31, 2009 
(ML100060387). After the comment period closed, the NRC received 
additional comments from the Nuclear Energy Institute in an e-mail 
dated January 6, 2010 (ML100280648). No other comments were received. 
The NRC staff considered all the comments in developing the final LR-
ISG-2009-01, as discussed in the ``Comments and Responses'' section of 
this notice.

Final Action

    By this action, the NRC is making the final LR-ISG-2009-01 
available. The NRC staff approves of the LR-ISG for NRC staff and 
stakeholder use. The NRC staff will also incorporate the approved LR-
ISG into the next revision of the GALL Report and the SRP-LR.
    The final LR-ISG revises the staff's aging management 
recommendations concerning spent fuel pool neutron-absorbing materials 
other than Boraflex, which are currently described in the GALL Report 
and SRP-LR. Specifically, the LR-ISG provides a program for managing 
the effects of aging on these spent fuel pool neutron-absorbing 
materials, whereas before, a plant-specific program was recommended. In 
addition, the corresponding aging management review line items in both 
documents are clarified and reference the recommended program instead 
of recommending further evaluation. The final LR-ISG also includes 
corresponding revisions to the SRP-LR for the staff's review procedures 
and acceptance criteria concerning these spent fuel pool components and 
materials. The title of the LR-ISG has been changed from the draft 
title, ``Staff Guidance Regarding Plant-Specific Aging Management 
Review and Aging Management Program for the Neutron-Absorber Material 
in the Spent Fuel Pool Associated with License Renewal Applications,'' 
to the final, ``Aging Management of Spent Fuel Pool Neutron-Absorbing 
Materials other than Boraflex,'' to clarify that the LR-ISG provides 
guidance concerning generic, not plant-specific, aging management 
recommendations.

Comments and Responses

    The comment providers, in general, recommended clarifications to 
the draft LR-ISG. The NRC staff included these clarifications in the 
final LR-ISG as appropriate. One comment indicated that the aging 
management program in GALL Report, Volume 2, Section XI.M2, ``Water 
Chemistry,'' should be credited to manage the loss of material aging 
effect. Another comment requested the NRC staff to provide the 
technical justification for the testing frequency in the proposed aging 
management program. Based on its technical evaluations, the NRC staff 
did not make substantive revisions to the LR-ISG in response to these 
two comments. Detailed NRC staff responses to all comments are in an 
appendix to the final LR-ISG document.
