NUCLEAR REGULATORY COMMISSION

[NRC-2012-0282]


Preoperational Testing of Onsite Electric Power Systems To Verify 
Proper Load Group Assignments, Electrical Separation, and Redundancy

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
is issuing for public comment draft regulatory guide (DG), DG-1294, 
``Preoperational Testing of On-Site Electric Power Systems to Verify 
Proper Load Group Assignments, Electrical Separation, and Redundancy.'' 
DG-1294 is proposed Revision 1 of RG 1.41, dated March 1973. This 
revision expands the scope of the guide to encompass preoperational 
testing of electrical power systems used to meet current Station 
Blackout regulations, time requirements for startup and alignment of 
emergency power sources, and testing requirements for facilities 
licensed under 10 CFR Part 52.

DATES: Submit comments by January 31, 2013. Comments received after 
this date will be considered if it is practical to do so, but the NRC 
is able to ensure consideration only for comments received on or before 
this date. Although a time limit is given, comments and suggestions in 
connection with items for inclusion in guides currently being developed 
or improvements in all published guides are encouraged at any time.

remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a draft guide in the NRC's 
``Regulatory Guide'' series. This series was developed to describe and 
make available to the public such information as 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 draft regulatory guide entitled ``Preoperational Testing of On-
Site Electric Power Systems to Verify Proper Load Group Assignments, 
Electrical Separation, and Redundancy'' is temporarily identified by 
its task number, DG-1294. The DG-1294 is proposed Revision 1 of 
Regulatory Guide 1.41, ``Preoperational Testing of On-Site Electric 
Power Systems to Verify Proper Load Group Assignments, Electrical 
Separation, and Redundancy'' dated March 1973.
    Regulatory Guide 1.41 was developed to provide guidance on 
preoperational testing of on-site electrical power systems important to 
safety for load group assignments, electrical separation, and 
redundancy. The guide was first issued in 1973 and has not been revised 
despite multiple revisions to the underlying regulations. Since 1973 
the Commission has amended its regulations for loss of all alternating 
current power (Station Blackout) and loss of large areas of the plant 
due to explosions or fire, and has established a new combined 
(construction and operating) licensing process under 10 CFR part 52.
    This regulatory guide is being revised for three reasons: (1) To 
expand the scope of the guide to encompass preoperational tests for the 
electrical power systems used to meet the regulatory requirements 
addressing Station Blackout and loss of large areas of the plant due to 
explosions or fire; (2) to expand the scope of the guide to encompass 
testing the ability to meet time requirements for startup and alignment 
for use of electric power sources used to meet the regulatory 
requirements addressing Station Blackout and loss of large areas of the 
plant due to explosions or fire and (3) to update the guide references 
and address facilities licensed under 10 CFR part 52.

III. Backfitting and Issue Finality

    As discussed in the ``Implementation'' section of this regulatory 
guide, the NRC has no current intention to impose this regulatory guide 
on holders of current operating licenses or combined licenses. 
Accordingly, the issuance of this regulatory guide would not constitute 
``backfitting'' as defined in 10 CFR 50.109(a)(1) of the Backfit Rule 
or be otherwise inconsistent with the applicable issue finality 
provisions in 10 CFR part 52.
    This regulatory guide may be applied to applications for operating 
licenses and combined licenses docketed by the NRC as of the date of 
issuance of the final regulatory guide, as well as future applications 
for operating licenses and combined licenses submitted after the 
issuance of the regulatory guide. Such action would not constitute 
backfitting as defined in 10 CFR 50.109(a)(1) or be otherwise 
inconsistent with the applicable issue finality provision in 10 CFR 
part 52, inasmuch as such applicants or potential applicants are not 
within the scope of entities protected by the Backfit Rule or the 
relevant issue finality provisions in Part 52.

    Dated at Rockville, Maryland, this 15th day of November, 2012.
