NUCLEAR REGULATORY COMMISSION

Federal Register Volume 80, Issue 120 (June 23, 2015)

The U.S. Nuclear Regulatory Commission (NRC) has granted the request of the Tennessee Valley Authority (TVA, the licensee) to withdraw its application dated November 22, 2013, as supplemented by letters dated April 4, August 15, September 30, 2014, and January 29, 2015, for a proposed amendment to Renewed Facility Operating License (RFOL) Nos. DPR-33, DPR-52, and DPR-68, for the Browns Ferry Nuclear Plant, Units 1, 2, and 3 (Browns Ferry). The proposed amendment would have revised the Browns Ferry Technical Specifications to decrease the allowable leakage rate criteria for the Main Steam Isolation Valves (MSIVs).

withdraw its application dated November 22, 2013, as supplemented by 
letters dated April 4, August 15, September 30, 2014, and January 29,

SUPPLEMENTARY INFORMATION: The NRC has granted the request of the TVA 
to withdraw its November 22, 2013, application for the proposed 
amendment to RFOLs for Browns Ferry, located in Limestone County, AL.
    By letter dated November 22, 2013 (ADAMS Accession No. 
ML14015A403), as supplemented by letters dated April 4, August 15, 
September 30, 2014, and January 29, 2015 (ADAMS Accession Nos. 
ML14100A143, ML14230A827, ML14275A247, and ML15030A499, respectively), 
TVA proposed changing Browns Ferry Technical Specification 3.6.1.3, 
``Primary Containment Isolation Valves (PCIVs),'' to reduce the 
individual and total leakage rate through the MSIVs. In the TVA letter 
dated August 30, 2013, ``Updated Reply to Notice of Violation; EA-11-
252,'' the Alternative Leakage Treatment (ALT) Pathway was identified 
as being in a nonconforming/degraded condition. The corrective actions 
that were outlined to change the ALT Pathway included modification of 
licensing documents to show lower individual and total leakage rates 
through the MSIVs. The proposed change would have made the current 
passive secondary ALT Pathway the primary pathway and decreased the 
leakage rates from 100 standard cubic feet per hour (scfh) per valve to 
60 scfh for individual MSIVs and the combined leakage rates for all 
four main steam lines from 150 scfh to 85 scfh.
    The NRC published a Biweekly Notice in the Federal Register on 
April 8, 2014 (79 FR 19401), that gave notice that this proposed 
amendment was under consideration by the NRC. However, by letter dated 
May 29, 2015 (ADAMS Accession No ML15159B009), the licensee requested 
to withdraw the proposed amendment.

    Dated at Rockville, Maryland, this 16th day of June 2015.

    For the Nuclear Regulatory Commission.

Operating Reactor Licensing, Office of Nuclear Reactor Regulation.
