Notice of Availability of NUREG-1950: ``Disposition of Public Comments and Technical Bases for Changes in the License Renewal Guidance Documents NUREG-1801 and NUREG-1800''
The NRC staff is issuing NUREG-1950, ``Disposition of Public Comments and Technical Bases for Changes in the License Renewal Guidance Documents NUREG-1801 and NUREG-1800.'' This document is a knowledge management transfer document associated with Revision 2 of NUREG-1801, ``Generic Aging Lessons Learned (GALL) Report,'' and Revision 2 of NUREG-1800, ``Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants.'' The technical changes that were made when revising the guidance contained in NUREG-1801 are captured in this document, along with the supporting technical bases. Changes to NUREG-1800, many of which derive from the changes in NUREG-1801, are also discussed in this document. Consequently, this document provides an understanding of the underlying rationale used by the NRC to develop Revisions 2 of NUREG-1801 and NUREG-1800. This document also contains the NRC staff's analysis of the public comments received on the Draft Revisions 2 of both the GALL Report and the Standard Review Plan for License Renewal (SRP-LR), published for public comment in May 2010 (75 FR 27838), with the public comment period expiring on July 2, 2010. The disposition of the comments accepted by the NRC staff and used as basis for instituting a change to either the GALL Report or the SRP-LR are detailed in this document. In addition, the public comments that did not result in a change to either NUREG are also dispositioned, and a technical basis for the staff's handling of these comments is presented.
Requirements for Maintenance of Inspections, Tests, Analyses, and Acceptance Criteria
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is proposing to amend its regulations related to verification of nuclear power plant construction activities through inspections, tests, analyses, and acceptance criteria (ITAAC) under a combined license. Specifically, the NRC is proposing new provisions that apply after a licensee has completed an ITAAC and submitted an ITAAC closure notification. The new provisions would require licensees to report new information materially altering the basis for determining that either inspections, tests, or analyses were performed as required, or that acceptance criteria are met, and to notify the NRC of completion of all ITAAC activities. In addition, the NRC is proposing editorial corrections to existing language in the NRC's regulations to correct and clarify ambiguous language and make it consistent with language in the Atomic Energy Act of 1954, as amended (AEA).
Draft Regulatory Guide, Guidance for ITAAC Closure
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment Draft Regulatory Guide (DG)-1250, ``Guidance for ITAAC Closure Under 10 CFR Part 52.'' The DG-1250 describes a method that the staff of the NRC considers acceptable for use in satisfying the requirements for documenting the completion of inspections, tests, analyses, and acceptance criteria (ITAAC).
