UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 November 13, 2013 Mr. Timothy S. Rausch Senior Vice President and Chief Nuclear Officer PPL Susquehanna, LLC 769 Salem Boulevard Berwick, PA 18603-0467

SUBJECT:

SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2- REQUEST FOR ADDITIONAL INFORMATION REGARDING REQUEST TO CHANGE TECHNICAL SPECIFICATION 3.3.6.1 (TAC NOS. ME9607 AND ME9608)

Dear Mr. Rausch:

By letter dated June 6, 2013, 1 PPL Susquehanna, LLC (the licensee) submitted a license amendment request for Susquehanna Steam Electric Station, Units 1 and 2, for Nuclear Regulatory Commission (NRC) review and approval. The proposed amendments would change Technical Specification (TS) 3.3.6.1, "Primary Containment Isolation Instrumentation."

Specifically, the proposed amendments would add a footnote to Function 6c in TS Table 3.3.6.1-1. This change would allow only one Trip System to be operable in MODES 4 and 5 for the Manual Initiation Function for Shutdown Cooling System isolation.

The draft questions were sent to Mr. Duane Filchner, of your staff, to ensure that the questions were understandable, the regulatory basis for the questions was clear, and to determine if the information was previously docketed. On October 31, 2013, Mr. Filchner agreed that you would provide a response by December 6, 2013.

If you have any questions regarding this matter, please contact me at 301-415-4090.

Sincerely,

.-~~p Jf (Ji;J Jeffr~~. Project Manager Plant Licensing Branch 1-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-387 and 50-388
