NUCLEAR REGULATORY COMMISSION

[NRC-2016-0252]


Assumptions Used for Evaluating the Potential Radiological 
Consequences of a Fuel Handling Accident in the Fuel Handling and 
Storage Facility for Boiling and Pressurized Water Reactors

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory guide; withdrawal.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is withdrawing 
regulatory guide (RG) 1.25, ``Assumptions used for Evaluating the 
Potential Radiological Consequences of a Fuel Handling Accident in the 
Fuel Handling and Storage Facility for Boiling and Pressurized Water 
Reactors.'' This document is being withdrawn because the guidance 
contained in RG 1.25 has been superseded and is now incorporated into 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 RG 1.25, ``Assumptions 
used for Evaluating the Potential Radiological Consequences of a Fuel 
Handling Accident in the Fuel Handling and Storage Facility for Boiling 
and Pressurized Water Reactors'' is December 12, 2016.

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SUPPLEMENTARY INFORMATION: Regulatory guides may be withdrawn by the 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superseded by technological innovations, congressional actions, or 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 issued RG 1.25, ``Assumptions used for Evaluating the 
Potential Radiological Consequences of a Fuel Handling Accident in the 
Fuel Handling and Storage Facility for Boiling and Pressurized Water 
Reactors,'' in March 1972 to provide guidance for the evaluation of the 
design basis fuel handling accident to demonstrate compliance with the 
NRC's regulations in part 100 of Title 10 of the Code of Federal 
Regulations. The NRC is withdrawing RG 1.25 because the guidance 
contained in RG 1.25 has been superseded by more current guidance, 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,'' and RG 1.195, ``Methods and Assumptions for Evaluating 
Radiological Consequences of Design Basis Accidents at Light-Water 
Nuclear Power Reactors.'' 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 RG 1.25 does not alter any prior or existing NRC 
licensing approval or the acceptability of licensee commitments to RG 
1.25. Although RG 1.25 is withdrawn, current licensees may continue to 
use it, and withdrawal does not affect any existing licenses or 
agreements. However, RG 1.25 should not be used in future requests or 
applications for NRC licensing actions.

    Dated at Rockville, Maryland, this 5th day of December, 2016.

    For the Nuclear Regulatory Commission.

Chief, Regulatory Guidance and Generic Issues Branch, Division of
