dated January 29, 2014 (Accession ML14042A115).

PPL Susquehanna, LLC (PPL) hereby withdraws, in its entirety, the License Amendment Request (LAR) referenced above for Susquehanna Steam Electric Station (SSES) Unit 1 and Unit 2. The LAR was previously needed for planned changes in analysis for the Control Room Habitability Envelope and Offsite Post LOCA Doses, to permit higher allowable Standby Gas Treatment System (SOTS) exhaust maximum flow rates from secondary containment. Subsequently, PPL implemented modifications and performed additional tests that indicate the LAR is no longer necessary to resolve margin concerns in meeting SOTS exhaust maximum flow rates from secondary containment. As a result, PPL is withdrawing the LAR at this time.

The withdrawal does not create any new regulatory commitments or revise any existing regulatory commitments.

If you have any questions or require additional information, please contact Mr. Duane L. Filchner (570) 542-6501.
