SUBJECT:

HOPE CREEK GENERATING STATION - REQUEST FOR ADDITIONAL INFORMATION REGARDING REQUEST FOR EXTENDED POWER UPRATE (TAC NO. MD3002)

Dear Mr. Levis:

By letter dated September 18, 2006,1 as supplemented by additional letters,2 PSEG Nuclear, LLC (PSEG or the licensee) submitted an amendment request for an extended power uprate (EPU) for the Hope Creek Generating Station (Hope Creek). The proposed amendment would increase the authorized maximum power level by approximately 15 percent, from 3,339 megawatts thermal (MWt) to 3,840 MWt.

The Nuclear Regulatory Commission (NRC) staff has been reviewing the submittal and has determined that additional information is needed to complete its review. The specific questions are found in the enclosed request for additional information (RAI). The questions were sent by e-mail to your staff and were discussed on a phone call on January 14, 2008, to ensure that the questions were understandable, the regulatory basis was clear and to determine if the information was previously docketed.

Mr. Jeff Keenan of your staff agreed to respond by January 25, 2008, to the enclosed RAI questions.

REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED LICENSE AMENDMENT EXTENDED POWER UPRATE HOPE CREEK GENERATING STATION DOCKET NO. 50-354 By letter dated September 18, 2006,1 as supplemented by additional letters,2 PSEG Nuclear, LLC (PSEG or the licensee) submitted an amendment request for an extended power uprate (EPU) for the Hope Creek Generating Station (Hope Creek). The proposed amendment would increase the authorized maximum power level by approximately 15 percent, from the current licensed thermal power (CLTP) of 3,339 megawatts thermal (MWt) to 3,840 MWt.

The Nuclear Regulatory Commission staff has reviewed the information the licensee provided that supports the proposed amendment and would like to discuss the following issues to clarify the submittal.

RAI 14.66 2nd Follow-Up - I Page 22 of Continuum Dynamics, Inc. (CDI) Report 07-27P, Finite Element Modeling Bias and Uncertainty Estimates Derived from the Hope Creek Unit 2 Dryer Shaker Test, Rev. 0, presents damping values computed for the finite element (FE) model to best match FE and measured acceleration response function peaks. CDI states that the inferred FE damping values are consistent with measured damping values in STI Technologies Report PA2168, Hope Creek Steam Dryer Vibration Test. However, no damping values (other than those for low frequency rigid body modes) are presented in the STI report.

(a) Provide and plot the damping values from the measurements as a function of shaker location and frequency. Also include minimum, maximum, mean, and root mean square values (computed over frequency) for each shaker location consistent with those in Table 3 in CDI Report 07-27P.

(b) Plot and compare the measured damping values and FE damping values inferred in CDI Report No.07-27P as a function of frequency and shaker location.

(c) Reconcile the differences between the measured and inferred FE damping values, and provide the resulting FE bias and uncertainty.

RAI 14.66 2nd Follow-Up - II STI Technologies Report PA2168, Hope Creek Steam Dryer Vibration Test states on page 7 that a Hanning window was applied to the measured vibration response. Hanning windows reduce peak amplitudes in Fourier Transforms. Was the Hanning window used during the peak response measurements conducted by driving the shaker at a single frequency? If so, how has the peak amplitude reduction been accounted for?
