SUPPLEMENTARY INFORMATION: The NRC has granted the request of Exelon to 
withdraw its application dated October 29, 2020 (ADAMS Package 
Accession No. ML20304A147) for proposed amendments to Renewed Facility 
Operating License Nos. NPF-37 and NPF-66 for Byron Station, Unit Nos. 1 
and 2, respectively, which are located in Ogle County, Illinois. Exelon 
is the licensee that owns and operates Byron. The proposed amendments 
would have changed the Byron TSs to permit changes in plant operations 
when the plants are permanently shut down and defueled. Specifically, 
the proposed amendments would have revised the Byron renewed facility 
operating licenses and TSs following the permanent cessation of power 
operations to reflect the post-shutdown and permanently defueled 
condition of the units. The proposed amendments would have eliminated 
TS requirements and license conditions that would not have been 
applicable once Byron ceased power operations and could no longer place 
fuel in the reactor vessels. The proposed amendments would have also 
eliminated obsolete license conditions. Additionally, the proposed 
amendments would have revised several license conditions and TS 
requirements, including limiting conditions for operation, usage rules, 
definitions, surveillance requirements, and administrative controls. 
The licensing bases for Byron, including the design bases accident 
analysis, would have also been revised.
    The Commission previously issued a proposed finding that the 
proposed amendments involve no significant hazards consideration 
published in the Federal Register on December 29, 2020 (85 FR 85677). 
However, by letter dated September 15, 2021 (ADAMS Accession No. 
ML21258A276), Exelon requested to withdraw the proposed amendments.

    Dated: September 28, 2021.

Operating Reactor Licensing, Office of Nuclear Reactor Regulation.
