NUCLEAR REGULATORY COMMISSION
[NRC-2016-0246]
Withdrawal of Regulatory Guides 1.3, 1.4, and 1.5
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory Guides 1.3, 1.4, and 1.5; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is withdrawing
three regulatory guides (RGs): RG 1.3, Revision 2, ``Assumptions Used
for Evaluating the Potential Radiological Consequences of a Loss of
Coolant Accident for Boiling Water Reactors,'' dated June 1974; RG 1.4,
Revision 2, ``Assumptions Used for Evaluating the Potential
Radiological Consequences of a Loss of Coolant Accident for Pressurized
Water Reactors,'' dated June 1974; and RG 1.5 (Safety Guide 5),
``Assumptions Used for Evaluating the Potential Radiological
Consequences of a Steam Line Break Accident for Boiling Water
Reactors,'' dated March 1971. These three RGs are being withdrawn
because the guidance contained in them has been superseded and is now
incorporated into RG 1.183, ``Alternative Radiological Source Terms for
Evaluating Design Basis Accidents at Nuclear Power Reactors,'' and RG
1.195, ``Methods and Assumptions for Evaluating Radiological
Consequences of Design Basis Accidents at Light-Water Nuclear Power
Reactors.''
DATES: The effective date of the withdrawal of RGs 1.3, 1.4, and 1.5 is
December 8, 2016.

ADAMS accession number for each document referenced in this document
(if that document is available in ADAMS) is provided the first time
that a document is referenced. The withdrawal notices for RGs 1.3, 1.4,
and 1.5 are available in ADAMS under Accession No. ML16210A319.

FOR FURTHER INFORMATION CONTACT: John Parillo, Office of Nuclear
Reactor Regulation, telephone: 301-415-1344; email
[email protected]; or Mark Orr, Office of Nuclear Regulatory
Research, telephone: 301-415-6003; email: [email protected]. Both are
staff of the U.S. Nuclear Regulatory Commission, Washington, DC 20555-
0001.
SUPPLEMENTARY INFORMATION: Regulatory guides may be withdrawn by the
NRC when their guidance no longer provides useful information, or is
superseded by technological innovations, congressional actions, or
other events. The withdrawal of an RG should be thought of as the final
revision of the guide.
The NRC is withdrawing RG 1.3, Revision 2, ``Assumptions Used for
Evaluating the Potential Radiological Consequences of a Loss of Coolant
Accident for Boiling Water Reactors,'' dated June 1974 (ADAMS Accession
No. ML16215A353); RG 1.4, Revision 2, ``Assumptions Used for Evaluating
the Potential Radiological Consequences of a Loss of Coolant Accident
for Pressurized Water Reactors,'' dated June 1974 (ADAMS Accession No.
ML16215A351); and RG 1.5 (Safety Guide 5), ``Assumptions Used for
Evaluating the Potential Radiological Consequences of a Steam Line
Break Accident for Boiling Water Reactors,'' dated March 1971 (ADAMS
Accession No. ML16215A352).
The NRC is withdrawing these three RGs because the guidance
contained in them has been superseded by more current guidance which
has been incorporated into RG 1.183, ``Alternative Radiological Source
Terms for Evaluating Design Basis Accidents at Nuclear Power
Reactors,'' (ADAMS Accession No. ML003716792), and RG 1.195, ``Methods
and Assumptions for Evaluating Radiological Consequences of Design
Basis Accidents at Light-Water Nuclear Power Reactors,'' (ADAMS
Accession No. ML031490640). The information in RG 1.183 provides
guidance for new and existing light-water reactor (LWR) plants that
have adopted the alternative source term (AST), and RG 1.195 provides
guidance for those LWR plants that have not adopted the AST.
The withdrawal of RGs 1.3, 1.4, and 1.5 does not alter any prior or
existing NRC licensing approval or the acceptability of licensee
commitments to these RGs. Although RGs 1.3, 1.4, and 1.5 are withdrawn,
current licensees may continue to use them, and withdrawal does not
affect any existing licenses or agreements. However, by withdrawing RGs
1.3, 1.4, and 1.5, the NRC no longer approves for use the guidance in
these RGs in future requests or applications for NRC licensing actions.
Dated at Rockville, Maryland, this 2nd day of December, 2016.
