SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION NINE MILE POINT UNIT 2 (NMP2) EXTENDED POWER UPRATE APPLICATION LICENSE AMENDMENT REQUEST (TAC NO. ME1476)
By letter dated May 27, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML091610103), Nine Mile Point Nuclear Station, LLC (NMPNS) submitted a license amendment request for Nine Mile Point, Unit No. 2 (NMP2). The proposed amendment requests an increase in the maximum steady-state power level at NMP2 from 3467 megawatts thermal (MWt) to 3988 MWt. This represents a 15-percent increase over the current licensed thermal power (CLTP). In response to the acceptance review comments by the staff, NMPNS submitted supplemental information by letter dated August 28, 2009.
Based on the staffs review of the amendment request and the supplemental information, the Mechanical and Civil Engineering Branch (EMCB) has identified areas for which additional information is required regarding the NMP2 steam dryer (SD). A response to the enclosed Request for Additional Information is needed before staff can complete its review.

NINE MILE POINT NUCLEAR STATION, UNIT NO.2 (NMP2)
EXTENDED POWER UPRATE (EPU)
LICENSE AMENDMENT REQUEST (LAR)
NINE MILE POINT NUCLEAR STATION, LLC (NMPNS)
DOCKET NO. 50-410 TAC NO. ME1476 By letter dated May 27, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML091610103), Nine Mile Point Nuclear Station, LLC (NMPNS) submitted a license amendment request for Nine Mile Point, Unit No. 2 (NMP2). The proposed amendment requests an increase in the maximum steady-state power level at NMP2 from 3467 megawatts thermal (MWt) to 3988 MWt. This represents a 15-percent increase over the current licensed thermal power (CLTP). In response to the acceptance review comments by the staff, NMPNS submitted supplemental information by letter dated August 28, 2009.
Based on the staffs review of the amendment request and the supplemental information provided by the licensee, the Mechanical and Civil Engineering Branch (EMCB) has identified areas for which additional information is required regarding the NMP2 steam dryer (SD).
NMP2-EMCB-SD-RAI-1: In the executive summary report (Attachment 13.0) and in the executive summary and references of the CDI Report 09-26P, Stress Assessment of Nine Mile Point Unit 2 Steam Dryer at CLTP and EPU Conditions, the applicant refers to the BWRVIP-194 Report, BWR Vessel and Internals Project, Methodologies for Demonstrating Steam Dryer Integrity for Power Uprate. The applicant also states that the steam dryer integrity analysis has followed the guidelines outlined in this report. The applicant is requested to omit references to the BWRVIP-194 topical report, Methodologies for Demonstrating Steam Dryer Integrity for Power Uprate, in its application, as it has neither been reviewed nor approved by the NRC staff. The licensee is requested to supplement the necessary information as stand-alone information in the EPU application rather than referencing the topical report that is not yet endorsed by the NRC.
In Attachments 13 and 13.1, the licensee references BWRVIP topical reports, BWRVIP-181, Steam Dryer Repair Design Criteria, and BWRVIP-182, Guidance for Demonstration of Steam Dryer Integrity for Power Uprate, that have not been reviewed nor approved by the staff. These topical reports are currently being reviewed by the staff. Reference to such unapproved documents is not acceptable. The licensee is requested to supplement the necessary information as stand-alone information in the EPU application rather than referencing the topical reports that are not yet endorsed by the NRC.
NMP2-EMCB-SD-RAI-2: Table 4 in SIA Calculation NMP-26Q-302R0 (Attachment 13.4) presents the frequencies of the peaks which were removed from the strain gage power spectra.
Some of these peaks are identified to be related to the pump vane pass frequencies, but others are referred to as non-identified sources. The licensee is requested to include in its submittal, the rationale of filtering these spectral peaks for which the sources have not been identified.
ENCLOSURE
NMP2-EMCB-SD-RAI-3: In CDI Report No.08-08P, Acoustic and Low Frequency Hydrodynamic Loads at CLTP Power Level on Nine Mile Point, Unit 2 Steam Dryer to 250 Hz., the Electrical Interference Check (EIC) signals are filtered out from the CLTP signals to estimate the dryer load by means of the Acoustic Circuit Model (ACM), Rev. 4. However, the EIC signals are not provided in CDI Report No.08-08P. The licensee is requested to revise this report to include:
- a. CLTP signals at all locations on the MSLs, before subtracting the EIC signals,
- b. The EIC signals at all locations for CLTP condition, and
- c. CLTP signals after subtracting the EIC signals.
The licensee is requested to provide this information in the form of overlapping power spectral density (PSD) plots for each location, separately, to facilitate comparisons between the various signals.
NMP2-EMCB-SD-RAI-4: Attachment 13.2 (CDI Report 08-08P Rev.1) provides sample level 1 and level 2 limit curves for MSL-A upper and lower locations. The licensee is requested to (a) describe what is meant by sample limit curves; (b) clarify if the sample limit curves are NMP2 specific limit curves; and (c) provide the limit curves for all four NMP2 MSL lines.
NMP2-EMCB-SD-RAI-5: Appendix-A of CDI Report 09-26P describes the methodology used for submodeling the four locations with the stress reduction factors (SRFs) ranging from 0.62 to 0.88. Item 6 of Table 7 of CDI Report 09-26P lists an SRF of 0.79, but does not describe the submodeling methodology used for the location of the bottom of the hood/hood support weld at junctions of the base plate. The licensee is requested to address and clarify whether the submodeling methodology used for this location is the same as in Appendix-A, or discuss whether a non-standard submodeling approach was used. Also, the licensee is requested to provide a discussion of whether the forces and displacements at the cut boundary of the global shell model were imported to the solid submodel. The staff does not endorse non-standard and unconventional submodeling approaches that use non-unique and arbitrary loading or displacements along with some arbitrary boundary conditions, to establish the applicable SRF value.
