II. Additional Information The NRC is issuing for public comment a DG in the NRC’s ‘‘Regulatory Guide’’ series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the NRC’s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. The DG, entitled, ‘‘Alternate RiskInformed Approach for Addressing the Effects of Debris On Post-Accident Long-Term Core Cooling,’’ is a proposed new guide temporarily identified by its task number, DG–1322. This DG–1322 proposes new guidance that describes methods and procedures that the staff considers acceptable for complying with a voluntary, risk-informed alternative in a proposed revision of the NRC’s regulation governing the design of ECCS, section 50.46c of Title 10 of the E:\FR\FM\20APP1.SGM 20APP1 Federal Register / Vol. 80, No. 75 / Monday, April 20, 2015 / Proposed Rules Code of Federal Regulations (10 CFR), ‘‘Emergency core cooling system performance during loss-of-coolant accidents (LOCA),’’ with respect to the effects of debris during long-term cooling. The voluntary alternative was included in the proposed 10 CFR 50.46c rule at the direction of the Commission in the Staff Requirements Memorandum (SRM) regarding SECY–12–0093 ‘‘Closure Options for Generic Safety Issue—191, Assessment of Debris Accumulation on Pressurized-Water Reactor Sump Performance,’’ and in the SRM regarding SECY–12–0034 ‘‘Proposed Rulemaking—10 CFR 50.46c: Emergency Core Cooling System Performance During Loss-of-Coolant Accidents (RIN 3150–AH42).’’ This guide is intended to provide a consistent approach for licensees to use when performing a risk assessment of the complex phenomena associated with debris generation and transport, and the resulting effect on long-term core cooling. mstockstill on DSK4VPTVN1PROD with PROPOSALS III. Backfitting and Issue Finality This DG, if finalized, would not constitute backfitting as defined in § 50.109 (the Backfit Rule), and would not be otherwise inconsistent with the issue finality provisions in 10 CFR part 52, ‘‘Licenses, Certifications and Approvals for Nuclear Power Plants.’’ The NRC published a proposed revision of 10 CFR 50.46c on March 24, 2014 (79 FR 16106). The proposed rule includes the option of allowing an applicant or licensee to address the effects of debris on longterm cooling with respect to ECCS performance requirements in § 50.46c and GDC–35 using a riskinformed approach. The proposed rule would also allow applicants and licensees who select the option to use the same approach in demonstrating compliance with GDC–38 and GDC–41. This DG provides guidance on one possible means for implementing that option. The proposed guidance does not exceed the scope of the proposed rule. Therefore, the backfitting and issue finality discussion for the proposed rule applies to this DG, and further consideration and discussion of backfitting and issue finality for the DG is not necessary.

Debris on Post-Accident Long-Term Core Cooling

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment draft regulatory guide (DG), DG-1322, ``Alternate Risk-
Informed Approach for Addressing the Effects of Debris On Post-Accident 
Long-Term Core Cooling.'' This DG proposes new guidance that describes

to the public or entering the comment submissions into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a DG in the NRC's 
``Regulatory Guide'' series. This series was developed to describe and 
make available to the public information regarding methods that are 
acceptable to the NRC staff for implementing specific parts of the 
NRC's regulations, techniques that the staff uses in evaluating 
specific problems or postulated accidents, and data that the staff 
needs in its review of applications for permits and licenses.
    The DG, entitled, ``Alternate Risk-Informed Approach for Addressing 
the Effects of Debris On Post-Accident Long-Term Core Cooling,'' is a 
proposed new guide temporarily identified by its task number, DG-1322. 
This DG-1322 proposes new guidance that describes methods and 
procedures that the staff considers acceptable for complying with a 
voluntary, risk-informed alternative in a proposed revision of the 
NRC's regulation governing the design of ECCS, section 50.46c of Title 
10 of the

[[Page 21659]]

Code of Federal Regulations (10 CFR), ``Emergency core cooling system 
performance during loss-of-coolant accidents (LOCA),'' with respect to 
the effects of debris during long-term cooling.
    The voluntary alternative was included in the proposed 10 CFR 
50.46c rule at the direction of the Commission in the Staff 
Requirements Memorandum (SRM) regarding SECY-12-0093 ``Closure Options 
for Generic Safety Issue--191, Assessment of Debris Accumulation on 
Pressurized-Water Reactor Sump Performance,'' and in the SRM regarding 
SECY-12-0034 ``Proposed Rulemaking--10 CFR 50.46c: Emergency Core 
Cooling System Performance During Loss-of-Coolant Accidents (RIN 3150-
AH42).'' This guide is intended to provide a consistent approach for 
licensees to use when performing a risk assessment of the complex 
phenomena associated with debris generation and transport, and the 
resulting effect on long-term core cooling.

III. Backfitting and Issue Finality

    This DG, if finalized, would not constitute backfitting as defined 
in Sec.  50.109 (the Backfit Rule), and would not be otherwise 
inconsistent with the issue finality provisions in 10 CFR part 52, 
``Licenses, Certifications and Approvals for Nuclear Power Plants.'' 
The NRC published a proposed revision of 10 CFR 50.46c on March 24, 
2014 (79 FR 16106). The proposed rule includes the option of allowing 
an applicant or licensee to address the effects of debris on longterm 
cooling with respect to ECCS performance requirements in Sec.  50.46c 
and GDC-35 using a risk-informed approach. The proposed rule would also 
allow applicants and licensees who select the option to use the same 
approach in demonstrating compliance with GDC-38 and GDC-41. This DG 
provides guidance on one possible means for implementing that option. 
The proposed guidance does not exceed the scope of the proposed rule. 
Therefore, the backfitting and issue finality discussion for the 
proposed rule applies to this DG, and further consideration and 
discussion of backfitting and issue finality for the DG is not 
necessary.

    Dated at Rockville, Maryland, this 13th day of April 2015.

    For the Nuclear Regulatory Commission.
