ProposedAmendment No. 269 to Unit I License NPF-14 and ProposedAmendment No. 236 to Unit 2 License NPF-22:

"DC ElectricalPowerSystems Technical Specifications Rewrite,"

dated November 9, 2004.

The purpose of this letter is to supplement the referenced amendment request, which proposed changes to the SSES Units 1 and 2 Technical Specification (TS) 3.8.6. The revised markups, included herein as Attachment 1, provide the information discussed during a teleconference held between R. V. Guzman (NRC) and D. L. Filchner (PPL Susquehanna, LLC) on February 16, 2006.

Specifically, the markups of TS LCO 3.8.6 Conditions A, B, C, and D, previously submitted in Reference 1 are revised such that the "and/or" in each of these LCO conditions is withdrawn and replaced with "or." This revised wording is consistent with PPL's current TS and the intent of TSTF-360 for DC Electrical Power Systems TS Rewrite.

PPL has reviewed the previously submitted "No Significant Hazards Consideration" and the "Environmental Consideration" relative to these revisions. We have determined that there are no changes required to either of these documents.

Document Control Desk PLA-6023 Please direct any questions regarding this response to Mr. Duane L. Filchner at (610) 774-7819.
