NUREG; issuance.


The U.S. Nuclear Regulatory Commission (NRC) is issuing final NUREG-2191, “Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report,” Vol. 1 and Vol. 2, and NUREG-2192, “Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants” (SRP-SLR). These final documents describe methods acceptable to the NRC staff for granting a subsequent license renewal in accordance with the license renewal regulations, as well as techniques that will be used by the NRC staff in evaluating applications for subsequent license renewal.

I. Discussion

The Atomic Energy Act (AEA) of 1954, as amended, authorizes the NRC to issue 40-year initial licenses and upon application and approval, subsequently renew licenses for nuclear power reactors. The NRC's regulations permit these licenses to be renewed beyond the initial 40-year term for an additional period of time, limited to 20-year increments per renewal, based on the outcome of an assessment to determine if the nuclear facility can continue to operate safely during the period of extended operation. There are no limitations in the AEA or the NRC's regulations restricting the number of times a license may be renewed.

The nuclear power industry has sent letters of intent to apply for subsequent license renewals in fiscal years 2018 and 2019. Subsequent License Renewal is a term referring to all license renewals allowing a plant to operate beyond the 60-year period (40-year of an initial operating license and a 20-year period of the first license renewal). Based on a survey conducted by the nuclear power industry and provided to the NRC, the NRC staff believes that additional applications for subsequent license renewal will be submitted in future years.

The NRC developed guidance for licensees that intend to apply for subsequent license renewal. The guidance documents for first license renewal (i.e., for operation from 40 to 60 years), the Generic Aging Lessons Learned Report, Revision 2 (GALL Report Rev. 2, ADAMS Accession No. ML103490041), and the Standard Review Plan for Review of License Renewal Applications, Revision 2 (SRP-LR Rev. 2, ADAMS Accession No. ML103490036) were revised to reflect aging differences for increased operating time from 60 to 80 years. The guidance was also revised to consider new operating experience and provide information identified as missing since the release of GALL Report Rev. 2. The GALL-SLR Report and SRP-SLR also include changes that have been previously issued for public comment as part of the staff's license renewal Interim Staff Guidance (ISG) process. These ISGs can be found at​reading-rm/​doc-collections/​isg/​license-renewal.html. These ISGs (ML12286A275, ML11297A085, ML12138A296, ML12270A436, ML12044A215, ML12352A057, ML13227A361, ML15308A018, and ML16237A383) have been incorporated into the GALL-SLR Report and the associated sections of the SRP-SLR. The NRC has previously received public comments on these ISGs, and is not requesting additional comments.

A notice of availability, requesting comment on the draft Guidance Documents was published in the Federal Register on December 23, 2015 (80 FR 79956). The public comment period ended on February 29, 2016. The NRC received 508 comments on these draft guidance documents. The NRC also published a supplement to the draft guidance documents in the Federal Register on March 29, 2016 (81 FR 17500). The public comment period ended on May 31, 2016. The NRC reviewed and dispositioned all of the comments and is publishing the disposition of the comments and the technical bases for their disposition in companion NUREGs. The NRC's resolution of these comments are incorporated into the final subsequent license renewal guidance documents.

II. Congressional Review Act

This NUREG is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.
