NUCLEAR REGULATORY COMMISSION
10 CFR Part 50
[NRC-2010-0229]
RIN 3150-AH29
Plant-Specific Applicability of Transition Break Size Specified
in 10 CFR 50.46a
AGENCY: Nuclear Regulatory Commission.
ACTION: Draft regulatory guide; discontinuation and withdrawal.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is announcing the
discontinuation of further regulatory action on Draft Regulatory Guide
(DG) DG-1216, ``Plant-Specific Applicability of Transition Break Size
Specified in 10 CFR 50.46a,'' and its withdrawal. Draft Regulatory
Guide DG-1216 was a proposed new regulatory guide written to provide
implementing guidance for a proposed rule ``Risk-Informed Changes to
Loss-of-Coolant Accident Technical Requirements,'' (Emergency core
cooling system (ECCS) rulemaking)) that provided a voluntary, alternate
approach for evaluating the performance of an ECCS. The NRC is
discontinuing further regulatory action on the DG and not publishing
the DG in final form because the NRC has discontinued the underlying
rulemaking.
DATES: The effective date for discontinuance and withdrawal of the DG
is December 8, 2016.

SUPPLEMENTARY INFORMATION: The NRC is announcing the discontinuation of
further NRC action on DG-1216, ``Plant-Specific Applicability of
Transition Break Size Specified in 10 CFR 50.46a,'' and its withdrawal.
This draft guide describes a method that the NRC considered acceptable
for demonstrating that the generic transition break size specified in
the proposed 10 CFR 50.46a ECCS rule was applicable to a specific
plant. The NRC provided an opportunity for public comment on DG-1216 in
the Federal Register on June 28, 2010 (75 FR 36698). The DG package
(ADAMS Accession No. ML100430352) consists of DG-1216 (ADAMS Accession
No. ML100430356), a Federal Register notice (FRN) (ADAMS Accession No.
ML100430445), and a regulatory analysis (ADAMS Accession No.
ML101530472).
Draft Regulatory Guide DG-1216 was a proposed new regulatory guide
written to provide implementing guidance for a proposed ECCS rulemaking
which would have provided a voluntary, risk-informed alternative to the
existing, deterministic requirements for evaluating ECCS performance.
The proposed ECCS rule was published in the Federal Register on
November 7, 2005 (70 FR 67597), with a supplemental proposed rule
published on August 10, 2009 (74 FR 40006). In SECY-16-0009,
``Recommendations Resulting from the Integrated Prioritization and Re-
Baselining of Agency Activities,'' dated January 31, 2016 (ADAMS
Accession No. ML16028A189), the staff recommended that the ECCS
rulemaking be discontinued. In the Staff Requirements Memorandum for
SECY-16-0009, dated April 13, 2016 (ADAMS Accession No. ML16104A158),
the Commission approved discontinuation of the ECCS rulemaking. The NRC
published an FRN on October 6, 2016 (81 FR 69446), which provided a
discussion of the discontinuation decision.
Because the NRC discontinued the ECCS rulemaking, further NRC
action to develop and adopt DG-1216 as a final guidance document is not
needed. Therefore, this notice announces the NRC's decision to
discontinue further action on DG-1216 and documents the final NRC
action on DG-1216.
Dated at Rockville, Maryland, this 2nd day of December, 2016.
For the Nuclear Regulatory Commission.
