"Units 1 and 2 License Renewal Application (LRA) Extended Power Uprate (EPU)

Impacts on LRA " dated February7, 2008.

In accordance with the requirements of 10 CFR 50, 51, and 54, PPL Susquehanna, LLC (PPL) requested the renewal of the operating licenses for the Susquehanna Steam Electric Station (SSES) Units 1 and 2 in Reference 1.

The License Renewal Rule, 10 CFR 54.21(b), requires that each year following submittal of a license renewal application (LRA), and at least 3 months before scheduled completion of the NRC review, an amendment to the renewal application must be submitted that identifies any change to the current licensing basis (CLB) of the facility that materially affects the content of the LRA.

In accordance with this requirement, PPL performed a review of CLB changes since the submittal of Reference 2, to determine whether any sections of the LRA were affected by these changes.

The PPL review identified that NRC's issuance of SSES license amendments for implementation of Extended Power Uprate (EPU) on Units 1 and 2 did affect the SSES CLB. However, these amendments were previously anticipated and incorporated in the

Document Control Desk PLA-6429 LRA submittal in September 2006 (Reference 1), and PPL has confirmed that the final amendments, as issued, do not require any additional changes to the LRA, consistent with the discussion in Reference 3.

The PPL review also identified one engineering change that has been implemented at SSES subsequent to the Reference 2 submittal that materially affected the contents of the LRA. This change relocated an HVAC system air intake, which resulted in material and environment combinations that had not been previously evaluated in the SSES LRA. The enclosure to this letter provides an amendment to various sections of the SSES LRA to address this change.

If you have any questions, please contact Mr. Duane L Filchner at (610) 774-7819.

I declare, under penalty of perjury, that the foregoing is true and correct.

Enclosure to PLA-6429 Amendment to SSES License Renewal Application (LRA)

Second Annual (2008) Update

Enclosure to PLA-6429 Page 1 of 3 LRA Amendment As part of implementation of the Alternate Source Term (AST), PPL modification EC 793950 extended the control room air intake ductwork. This extension added ductwork and supports on the exterior of the Control Structure and Reactor Building.

The environments for Ductwork, Duct Bolting, Flexible Connections (ductwork) and HVAC Duct Supports originally identified in the LRA do not account for Outdoor Air and Exposed to Weather environments. The added ductwork is evaluated with the Standby Gas Treatment System (SGTS) described in LRA Section 2.3.2.7, as it provides the path for outdoor makeup air to SGTS.

The SSES LRA is amended as follows:
