SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) staff is issuing 
Final Interim Staff Guidance (ISG) DC/COL-ISG-013 and DC/COL-ISG-014. 
ISG-013 supplements NUREG-0800 Standard Review Plan (SRP) Section 11.2 
and Branch Technical Position 11-6 and ISG-014 supplements SRP Sections 
2.4.12 and 2.4.13. The purpose of these ISGs is to provide staff 
guidance for assessing combined license (COL) applicant compliance with 
acceptance criteria.

DATES: The effective date of the COL-ISGs is February 28, 2013.

SUPPLEMENTARY INFORMATION: 

I. Discussion

    In reviewing applications for certified designs and combined 
licenses under part 52 of Title 10 of the Code of Federal Regulations 
(10 CFR), the NRC staff found that the March 2007, SRP staff guidance 
did not provide sufficient guidance to adequately evaluate applicants' 
approach in modeling the movement of radioactivity and in assessing the 
radiological impacts following the postulated failure of a tank 
containing radioactive materials. The two ISGs are being issued 
simultaneously because they are intended to be used together. ISG-013 
addresses the development of the radiological source term contained in 
the postulated tank failure and mechanism for the radioactivity to 
reach groundwater or surface water, while ISG-014 focuses on 
characterizing the hydro-geologic conditions of the site where 
radioactivity is assumed to enter groundwater or surface water and 
modeling the movement of the radioactivity to points beyond the site 
boundary.

II. Background

    The staff issues COL-ISGs to facilitate timely implementation of 
current staff guidance and to facilitate activities associated with 
review of applications for COL-ISGs by the staff. These ISGs supplement 
the guidance contained in Regulatory Guide (RG) 1.206, Revision 0, 
``Combined License Applications for Nuclear Power Plants (LWR 
Edition).'' In addition, these ISGs supplement the guidance provided 
for staff review of COL applications contained in NUREG-0800, SRP dated 
March 2007. The NRC staff intends to incorporate these final ISGs into 
the next revision of RG 1.206 and NUREG-0800. On February 24, 2010 (75 
FR 8411 and 75 FR 8412), the staff reopened the comment period for the 
proposed draft DC/COL-ISG-013, under ADAMS Accession No. ML090830488 
and issued the proposed draft DC/COL-ISG-014, under ADAMS Accession No. 
ML091320560 for public comment. The staff received questions and 
editorial comments which were considered in the development of the 
final ISGs. The questions, comments, and staff resolutions of those 
comments are contained in ``DC/COL-ISG-013 Comment Resolution'' which 
can be found under ADAMS Accession No. ML12191A346, and ``DC/COL-ISG-
014 Comment Resolution'' which can be found under ADAMS Accession No. 
ML12191A342. See NRC's public Web page: (http://www.nrc.gov/reading-rm/doc-collections/isg/).

III. Backfitting and Issue Finality

    Issuance of these ISGs does not constitute backfitting as defined 
in 10 CFR 50.109, nor is it inconsistent with any of the issue finality 
provisions in 10 CFR Part 52. These ISGs do not contain

[[Page 6150]]

any new requirements for COL applicants or holders under Part 52, or 
for licensees of existing operating units licensed under Part 50. 
Rather, they contain additional guidance and clarification on 
compliance with 10 CFR 50.34(h) and 10 CFR 52.79(a)(41), and may be 
used by operating license and COL applicants, respectively, in the 
preparation of their applications. As explained in the applicability 
section of each ISG, the ISGs do not apply to holders of nuclear power 
reactor operating licenses under 10 CFR Part 50 or combined licenses 
under 10 CFR Part 52 as of the effective date of these ISGs and, for 
ISG-014, the effective date of revision of SRP Section 2.4.13, and for 
applicants for nuclear power reactor operating licenses under 10 CFR 
Part 50 or combined licenses under 10 CFR Part 52 that have committed, 
in applications docketed with the NRC as of the effective date of this 
ISG and, for ISG-014, the effective date of revision of SRP Section 
2.4.13, to specific guidance in assessing the radiological consequences 
of a postulated failure of a tank containing radioactive materials.

Congressional Review Act

    Each of these ISGs is a rule as designated in the Congressional 
Review Act (5 U.S.C. 801-808). However, the Office of Management and 
Budget has not found either one to be a major rule as designated in the 
Congressional Review Act.
SUPPLEMENTARY INFORMATION: The agency posts its issued staff guidance 
in the agency external Web page (http://www.nrc.gov/reading-rm/doc-collections/isg/).
