SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing for public 
comment a draft guide in the agency'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 (DG), entitled, ``Availability of 
Electric Power Sources'' temporarily identified by its task number, DG-
1244, which should be mentioned in all related correspondence. DG-1244 
is proposed Revision 1 of Regulatory Guide 1.93, dated May 1974. This 
regulatory guide describes guidelines that the staff of the U.S. 
Nuclear Regulatory Commission (NRC) considers acceptable when the 
available electric power sources are less than the number of sources 
required by the limiting conditions for operation (LCOs) for a 
facility. This regulatory guide is applicable to single- and multiple-
unit plants and is consistent with the improved Standard Technical 
Specifications (iSTS). The LCO-required

actions and specified completion times referred to in this regulatory 
guide are based on the completion times presented in Regulatory Guide 
1.93, ``Availability of Electric Power Sources,'' Revision 0, issued 
December 1974, which have been incorporated into the required actions 
in the iSTS.

II. Further Information

    The NRC staff is soliciting comments on DG-1244. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-1244 in the subject line. Comments submitted in writing or 
in electronic form will be made available to the public in their 
entirety through the NRC's Agencywide Documents Access and Management 
System (ADAMS).

or contact information, the NRC cautions you against including any 
information in your submission that you do not want to be publicly 
disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their comments to remove any
