1) PPL Letter PLA-6076, B. T McKinney (PPL) to USNRC, "ProposedLicense Amendment Numbers 285for Unit 1 Operating License No. NPF-14 and 253 for Unit 2 OperatingLicense No. NPF-22 Constant PressurePower Uprate,"dated October 11, 2006.

Pursuant to 10 CFR 50.90, PPL Susquehanna LLC (PPL) requested in Reference I approval of amendments to the Susquehanna Steam Electric Station (SSES) Unit 1 and Unit 2 Operating Licenses (OLs) and Technical Specifications (TS) to increase the maximum power level authorized from 3489 megawatts thermal (MWt) to 3952 MWt, an approximate 13% increase in thermal power. The proposed Constant Pressure Power Uprate (CPPU) represents an increase of approximately 20% above the Original Licensed Thermal Power (OLTP).

The purpose of this letter is to provide supplemental information discussed in a teleconference held April 5, 2007.

The Enclosure contains the PPL responses.

There are no new regulatory commitments associated with this submittal.

Document Control Desk PLA-6187 PPL has reviewed the "No Significant Hazards Consideration" and the "Environmental Consideration" submitted with Reference 1 relative to the Enclosure. We have determined that there are no changes required to either of these documents.

If you have any questions or require additional information, please contact Mr. Michael H. Crowthers at (610) 774-7766.

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

PPL EPU Request for Additional Information Responses

Enclosure to PLA-6187 Page 1 of 1 NRC Question 1:

The Environmental Report (ER) reported a generation of solid waste, specifically with an irradiated component, for the year 2000 and 2003, at 190000 Ci and 107000 Ci, respectively. We'd like to understand if this is a regular occurrence and how often it occurs PPL Response:

The high activity levels of irradiated components for years 2000 and 2003 listed in the ER were mainly from disposal of radioactive solid wastes generated from activities that were not regular occurrences. These included control rod blades, fuel pool cleanout wastes, and reactor water filter resins. These wastes are usually stored onsite until enough is present to fill a container for transport to a disposal site. It should also be noted that "Table 8-1, SSES Low-Level Radioactive Waste Generation by Waste Type, 2000 - 2004" is incorrectly labelled. The table lists annual solid radioactive waste disposal data and not generation data as stated in the table's title. The data contained therein is consistent with the Final Environmental Statement (FES), Construction Permit Stage, 1973 referenced in the EPU ER (Section 8.1.1).

NRC Question 2:

The ER did not estimate the amount of activity (Ci) of solid waste due to the Power Uprate (EPU). Please provide an estimate.

PPL Response:

The Final Environmental Statement (FES), Construction Permit Stage, 1973 lists activity for solid radioactive wastes shipped offsite to be approximately 5,500 Ci per year. At the completion of EPU implementation, the rated power from the Susquehanna units will have been increased by 20 % over the licensed power proposed at the time of the 1973 FES. PPL, therefore, estimates 6,600 Ci (5,500 Ci x 1.2) as the annual amount of activity to be disposed offsite after implementation of the EPU.

Section 8.1.1 of the ER identifies that PPL estimates an approximate 11 percent increase in generation of Low-Level Radioactive Waste (LLRW). Correspondingly, PPL estimates an 11% increase in the amount of activity of disposed solid waste due to the EPU.
