The public should not provide comments to the early version of the ISG. The NRC posts all final ISGs on the NRC’s public Web page at https:// www.nrc.gov/reading-rm/doccollections/isg/, which is where the public may easily obtain access to DC/ COL–ISG–28. Backfitting and Issue Finality The NRC is proposing to issue interim guidance for the NRC staff for assessing the technical adequacy of probabilistic risk assessments submitted as part of advanced light-water reactor design certification applications and combined license applications. Issuance of the draft ISG, if finalized, would not constitute backfitting as defined section 50.109 of Title 10 of the Code of Federal Regulations (10 CFR) (the Backfit Rule) or otherwise be inconsistent with the issue finality provisions in 10 CFR part 52. The NRC’s position is based upon the following considerations. 1. The draft ISG positions, if finalized, do not constitute backfitting, inasmuch as the ISG is internal guidance to NRC staff. The ISG provides interim guidance to the staff on how to review an application for NRC regulatory approval in the form of licensing. Changes in internal staff guidance are not matters for which applicants or licensees are protected under 10 CFR 50.109 or issue finality provisions in part 52. 2. Backfitting and issue finality—with certain exceptions discussed below—do not protect current or future applicants. Applicants and potential applicants are not, with certain exceptions, protected by either the Backfit Rule or any issue finality provisions under 10 CFR part 52. This is because neither the Backfit Rule nor the issue finality provisions under 10 CFR part 52—with certain exclusions discussed below— were intended to apply to every NRC action that substantially changes the expectations of current and future applicants. The exceptions to the general principle are applicable whenever an applicant references a 10 CFR part 52 license (e.g., an early site permit), NRC regulatory approval (e.g., a design certification rule), or both, with specified issue finality provisions. The staff does not, at this time, intend to PO 00000 Frm 00078 Fmt 4703 Sfmt 9990 impose the positions represented in the draft ISG (if finalized) in a manner that is inconsistent with any issue finality provisions. If, in the future, the staff seeks to impose a position in the draft ISG (if finalized) in a manner that does not provide issue finality as described in the applicable issue finality provision, then the staff must address the criteria for avoiding issue finality as described in the applicable issue finality provision. 3. The staff has no intention to impose the draft ISG on existing nuclear power plant licenses or regulatory approvals either now or in the future (absent a voluntary request for change from the licensee, holder of a regulatory approval, or a design certification applicant). The staff does not intend to impose or apply the positions described in the draft ISG to existing (already issued) licenses (e.g., operating licenses and combined licenses) and regulatory approvals. Hence, the draft ISG—even if considered guidance which is within the purview of the issue finality provisions in 10 CFR part 52—need not be evaluated as if it were a backfit or as being inconsistent with issue finality provisions. If, in the future, the staff seeks to impose a position in the draft ISG (if finalized) on holders of already issued licenses in a manner that does not provide issue finality as described in the applicable issue finality provision, then the staff must make the showing as set forth in the Backfit Rule, or address the criteria for avoiding issue finality as described in the applicable issue finality provision, as applicable. Congressional Review Act This ISG 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 yet determined whether it is a major rule as defined in the Congressional Review Act.

II. Background

    The NRC staff issues DC/COL-ISGs to facilitate timely 
implementation of current staff guidance and to facilitate activities 
associated with review of applications for DCs and COLs by the Office 
of New Reactors. The NRC staff intends to incorporate the final 
approved DC/COL-ISG-28 into the next revision of Regulatory Guide (RG) 
1.200, Revision 2, ``An Approach for Determining the Technical Adequacy 
of Probabilistic Risk Assessment Results for Risk-Informed Activities'' 
(ADAMS Accession No. ML090410014), RG 1.206, ``Combined License 
Applications for Nuclear Power Plants'' (ADAMS Accession No. 
ML070720184), and NUREG-0800, ``Standard Review Plan (SRP) for the 
Review of Safety Analysis Reports for Nuclear Power Plants,'' SRP 
Section 19.0 ``Probabilistic Risk Assessment and Severe Accident 
Evaluation for New Reactors'' (ADAMS Accession No. ML12132A481), as 
appropriate.
    An early version of this ISG was made publicly available to support 
the September 9, 2014, meeting of the Working Group on Advanced Light 
Water Reactors for the American Society of Mechanical Engineers/
American Nuclear Society Joint Standards Committee on Nuclear Risk 
Management (ADAMS Accession No. ML14248A683). The public should not 
provide comments to the early version of the ISG.
    The NRC posts all final ISGs on the NRC's public Web page at https://www.nrc.gov/reading-rm/doc-collections/isg/, which is where the public 
may easily obtain access to DC/COL-ISG-28.

Backfitting and Issue Finality

    The NRC is proposing to issue interim guidance for the NRC staff 
for assessing the technical adequacy of probabilistic risk assessments 
submitted as part of advanced light-water reactor design certification 
applications and combined license applications. Issuance of the draft 
ISG, if finalized, would not constitute backfitting as defined section 
50.109 of Title 10 of the Code of Federal Regulations (10 CFR) (the 
Backfit Rule) or otherwise be inconsistent with the issue finality 
provisions in 10 CFR part 52. The NRC's position is based upon the 
following considerations.
    1. The draft ISG positions, if finalized, do not constitute 
backfitting, inasmuch as the ISG is internal guidance to NRC staff.
    The ISG provides interim guidance to the staff on how to review an 
application for NRC regulatory approval in the form of licensing. 
Changes in internal staff guidance are not matters for which applicants 
or licensees are protected under 10 CFR 50.109 or issue finality 
provisions in part 52.
    2. Backfitting and issue finality--with certain exceptions 
discussed below--do not protect current or future applicants.
    Applicants and potential applicants are not, with certain 
exceptions, protected by either the Backfit Rule or any issue finality 
provisions under 10 CFR part 52. This is because neither the Backfit 
Rule nor the issue finality provisions under 10 CFR part 52--with 
certain exclusions discussed below--were intended to apply to every NRC 
action that substantially changes the expectations of current and 
future applicants. The exceptions to the general principle are 
applicable whenever an applicant references a 10 CFR part 52 license 
(e.g., an early site permit), NRC regulatory approval (e.g., a design 
certification rule), or both, with specified issue finality provisions. 
The staff does not, at this time, intend to impose the positions 
represented in the draft ISG (if finalized) in a manner that is 
inconsistent with any issue finality provisions. If, in the future, the 
staff seeks to impose a position in the draft ISG (if finalized) in a 
manner that does not provide issue finality as described in the 
applicable issue finality provision, then the staff must address the 
criteria for avoiding issue finality as described in the applicable 
issue finality provision.
    3. The staff has no intention to impose the draft ISG on existing 
nuclear power plant licenses or regulatory approvals either now or in 
the future (absent a voluntary request for change from the licensee, 
holder of a regulatory approval, or a design certification applicant).
    The staff does not intend to impose or apply the positions 
described in the draft ISG to existing (already issued) licenses (e.g., 
operating licenses and combined licenses) and regulatory approvals. 
Hence, the draft ISG--even if considered guidance which is within the 
purview of the issue finality provisions in 10 CFR part 52--need not be 
evaluated as if it were a backfit or as being inconsistent with issue 
finality provisions. If, in the future, the staff seeks to impose a 
position in the draft ISG (if finalized) on holders of already issued 
licenses in a manner that does not provide issue finality as described 
in the applicable issue finality provision, then the staff must make 
the showing as set forth in the Backfit Rule, or address the criteria 
for avoiding issue finality as described in the applicable issue 
finality provision, as applicable.

Congressional Review Act

    This ISG 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 
yet determined whether it is a major rule as defined in the 
Congressional Review Act.

    Dated at Rockville, Maryland, this 18th day of November, 2014.
