2. Vermont Yankee Steam Dryer Monitoring Plan, Revision 3

Purpose:

The Vermont Yankee Steam Dryer Monitoring Plan, Reference 2, incorporates a revision to the Level 1 and Level 2 Limit Curves based on use of the existing Finite Element Model results using 1791 MWt data and a reduction of the limit factor based on the calculated increased in dryer stress intensity based on the 1872 MWt Strain Gage data. This document assesses compliance of Revision 3 to the Vermont Yankee Steam Dryer Monitoring Plan with Vermont Yankee (VY) License Condition 3.M.4. Discussion: On April 22, 2006 VY raised reactor power from 1792 MWt to 1832 MWt. This was followed on April 28, 2006 with power ascension to 1872 MWt. At the 1872 MWt power level, the upper and lower sets of strain gages on the 'A' main steam line provided indications at 143.5 Hz that exceeded the Level 2 Acceptance Criteria of the Steam Dryer Monitoring Plan (SDMP, Rev. 2). VY entered the event into the plant corrective action program and performed an engineering evaluation that concluded that continuous operation at the existing power level (1872 MWt) would not challenge steam dryer integrity. Entergy performed a review of the 1872 MWt data based on the results of the, ANSYS Finite Element Model (FEM) performed at 1791 MWt. This evaluation is contained in VYC-3001, Revision 2, Minor Calculation Change (MCC) 2. This evaluation shows that from 1791 MWt to 1872 MWt the stress on the steam dryer limiting component (gusset shoe) has increased from 2688 psi to 3599 psi. This new stress result from the Acoustic Circuit Model (ACM) method is combined.with the Computational Fluid Dynamics (CFD) Stress (599 psi) and results in a conservative reduction in the Level 1 limit factor from 3.53 to 2.64. Entergy also used the FEM results at 1791 MWt and the strain gage data at 1872 MWt to project the estimated total stress at full power (1912 MWt). The combined ACM and CFD stress at 1912 is estimated to be 4050 psi with 236 percent margin to the 13,600psi ASME limit. The use of the strain gage data from 1872 MWt in comparison with the 1791 MWt ACM/FEM results and generation of revised steam dryer limit curves has been assessed against the requirements of License Condition 3.M.4 which states:

    "When operating above OLTP, the operating limits, required actions, and surveillances specified in the SDMP shall be met. The following key attributes of the SDMP shall not be made less restrictive without prior NRC approval:

Page 2 of 3 a.. During initial power ascension testing above OLTP, each test plateau increment shall be approximately 80 MWt,

b. Level I performance criteria; and
c. The methodology for establishing the stress spectra used for the Level 1 and.

Level 2 performance criteria. Changes to other aspects of the SDMP may be made in accordance with the guidance of NEI 99-04." As described above, License Condition 3.M.4 specifies those attributes of the approach to steam dryer monitoring that require NRC approval prior to being made less restrictive. As addressed below, VY concludes that the key attributes have NOT been made less restricted and, therefore, the proposed model and limit curve changes do NOT require prior NRC approval. The following changes have been incorporated into the VY approach to steam dryer monitoring:

1. An updated Level 1 Limit Curve representing a conservative reduction of the Level 1 Limit Factor from 3.53 to 2.64 based on the values obtained in the 1872 MWt FEM/Strain Gage evaluation. The methodology for calculating the proposed limit curve factors at 1872 MWt is unchanged from themethodology employed for calculating the limit curve factors at the 1791 MWt power ascension plateau.
2. The FEM/Strain Gage Evaluation is based on using the results of the FEM performed using inputs from the last ACM runs (at the power ascension plateau of 1791 MWt) and, after determining the sensitivity of the FEM for each key in-plant acoustic frequency, calculating the change in the FEM results for the given Strain Gage changes. No new methodologies are employed to calculate these results. This technique for calculating the governing component stress intensity at 1871 MWt continues to rely on the governing principal of linear stress analysis in that a structure will experience an. increase in stress intensity linearly with an increase in applied load.

This revision of the SDMP was evaluated against the criteria in License Condition 3.M.4 to determine if NRC approval is required as summarized below:

a. This revision proposes no change in the test plateau increments from those specified in the criteria.
b. The Level 1 performance criteria is defined as a limit curve for strain gage results that represents a stress on the dryer equal to the ASME Design Limit of 13.6 ksi minus the calculated total model and measurement uncertainty. The updated. limit curves still represent the ASME criteria minus the calculated uncertainty.
c. The methodology for establishing stress spectra for the Level 1 and Level 2 criteria is not altered by this change.

Page 3 of.3 As required by License Condition 3.M the dryer component stress intensities are generated from the FEM. Post-processing of the FEM generates the relative contribution of the significant in-plant forcing function frequencies. The changes in main steam line strain gage

             .readings at these frequencies are then input into the calculation to develop a new resultant stress. This revised, conservatively determined stress is then used to generate revised Level. 1 and Level 2 limit factors and maintains the same ACM/FEM linearity and employs the same uncertainty values.

The above changes were evaluated using the guidance provided in NEI 99-04.:

== Conclusion:==

1. Based on the analysis performed using VYNPS Strain Gage data taken at the 1872 MWt plateau and employing the use of the frequency sensitivities generated by the ANSYS FEM there is significant margin to the ASME fatigue limit and the final 40 MWt power ascension is not expected to result in challenge to the Level 1 Limit Curve.
2. The SDMP has not been made less restrictive by the changes, made to the generation of the Level 1 Limit Factor based on the FEM/Strain Gage evaluation.

Therefore, prior NRC approval is not required to implement these changes. Preparer: Craig Nichols "- . . Name Signature -at Reviewer: James Callaghan - . Name Sip4 r Date Approver: John Dreyfuss

  • 2.2.6.2 Technical Evaluation 2.2.6.2.1 Steam Dryer As indicated in Attachment 5 to Supplement 26 (March 31, 2005) of its EPU request, the licensee originally procured the steam dryer for VYNPS as a non-safety-related, non-Seismic I, non-ASME component. In response to damage experienced by steam dryers at other nuclear power plants under EPU conditions, Entergy modified the square-hood steam dryer at VYNPS to improve its capability to withstand potential adverse flow effects that could result from operation of the plant at EPU conditions. In Supplement 8 (July 2, 2004) of its EPU request, the licensee described the modifications to the VYNPS steam dryer as follows:
  • outer vertical hood plates (61-inch high) on 90 and 270' sides replaced with 1-inch thick plate;
  • 3 reinforcing gussets (55.5-inch high) welded to outer vertical hood plates and lower horizontal cover plates on 900 and 2700 sides;
"    lower horizontal cover plates on 900 and 2700 sides replaced with 5/8-inch thick plate;
"    15-inch section of upper horizontal: cover plates on 900 and 2700 sides at intersection of outer vertical hood plates replaced with 1-inch thick plate;
"    internal bracing brackets at outer vertical hood plates removed; and
"    dryer bank tie. bars replaced with new design.

During a technical audit at the GE office in San Jose, CA, from August 24 to 26, 2004, NRC staff members from the Office of Nuclear Reactor Regulation (NRR) and Office of Nuclear Regulatory Research (RES) with technical assistance by contractors from the Argonne National Laboratory reviewed the VYNPS steam dryer analysis initially provided as part of the licensee's EPU request. As discussed in the audit report dated September 14, 2004, the NRC staff concluded that the licensee's analysis was inadequate to demonstrate that the steam dryer at the VYNPS will be capable of maintaining its structural integrity under EPU conditions. For example, the licensee's analysis of the steam dryer as then submitted in support of its EPU request (1) had not adequately identified and verified the excitation sources for FIV Docket No. 7195 Attachment 6-3 Page 2 of 12

mechanisms that resulted in significant degradation of similar steam dryers at other-BWR nuclear power plants operating at EPU conditions; (2) had 'not provided a technically justifiable load definition for the steam dryer for EPU conditions in light of several assumptions that had not been adequately justified; (3) had not justified the applied methodology as realistic. in light of assumptions to account for uncertainties that resulted in apparent significant overestimation of predicted steam dryer stresses; (4) might be non-conservative based on assumptions for reducing the stress experienced by steam dryer parts and the creation of new potential fatigue failure locations as a result of modifications to the VYNPS steam dryer; and (5) had not validated the extrapolation of pressure peaks from original. power.levels to EPU conditions for the steam dryer at VYNPS. In the audit'report, the NRC staff indicated that the licensee could submit a revised analysis of the steam dryer in support of its request to operate VYNPS at EPU

'conditions.

In Supplement 26 (March 31, 2005), Supplement 27 (April 5, 2005), and Supplement 29 (June 2, 2005) of its EPU request, Entergy provided a revised analysis of the capability of the modified VYNPS steam dryer to' maintain its structural integrity under EPU conditions, NRC staff members from NRR and RES have reviewed the revised VYNPS steam dryer analysis with technical assistance by contractors from the Argonne National Laboratory (including a consultant from the Pennsylvania State University), and McMaster University in Canada. On June 15 and 16, 2005, the NRC staff with its contractors conducted a technical audit of the revised analysis of the VYNPS steam dryer at toe GE office in Washington, DC. On July 27, 2005, the NRC staff provided a final RAI to Entergy on the revised analysis of the VYNPS steam dryer. On August 1 and 4, 2005, the lice hsee submitted a response to the RAI in Supplements 30 and 31 to its EPU request. On August 15 and 16, 2005, an NRC staff member and a contractor conducted an audit at the GE Scale Model Test (SMT) facility near San Jose, CA, to obtain information on the licensee's performance of tests to. validate the specific application of the acoustic circuit model (ACM) used by the licensee to determine the pressure loads on the VYNPS steam dryer during EPU operation. From August 22 to 25, 2005, the NRC staff with its contractors conducted a technical audit at the GE office in Washington, DC, of the revised analysis of the VYNPS steam dryer. In Supplement 33 (September 14, 2005) of its EPU request, the licensee provided revised RAI responses to address the NRC staff's findings from the August 22-25, 2005, audit. In Supplement 34 (September 18, 2005) of its EPU request, the licensee provided, among other information, several figures inadvertently omitted from Supplement 33. On December 5, 2005, the NRC staff conducted a follow-up audit to the June and August 2005 audits with licensee personnel at the Excel Corporation office in Rockville, MD, to verify appropriate finite element modeling of the connection of the gussets to the cover plate in the VYNPS steam dryer for the determination of stress at the connection under EPU conditions. As described in the applicable supplements to its EPU request, the licensee evaluated the pressure loads acting on the steam dryer during operation of VYNPS through computational fluid dynamics (CFD) and acoustic circuit model (ACM) analyses. The licensee used the CFD .analysis of the VYNPS steam dryer to predict hydrodynamic pressure loads that would act on the steam dryer at low frequencies under .CLTP and EPU conditions. The licensee used the ACM analysis to calculate the acoustic pressure loads acting at high frequencies on the VYNPS steam dryer at CLTP based on pressure fluctuations in the MSLs measured by pressure sensors installed on the MSL venturi lines and strain gages installed on the MSLs. The licensee performed transient and static stress analyses using an ANSYS finite element model (FEM) of the VYNPS steam dryer. The licensee calculated the stresses on the VYNPS steam Docket No. 7195 Attachment 6-3 Page 3 of 12

                                                  -43  -

dryer resulting from the CFD and ACM analyses, and combined those stresses by the square-root-of-the-sum-of-squares (SRSS) methodology with applicable weld concentration factors. The licensee then compared the peak alternating stresses for specific steam dryer locations to the fatigue limits in the ASME Code and the primary plus secondary stresses to the applicable ASME Code Service Level limits. In its review of the VYNPS steam dryer analysis, the NRC staff evaluated the licensee's validation of its CFD and ACM analyses, and the uncertainty of those analyses and their inputs. The staff reviewed the licensee's fundamental frequency and damping assumptions for the VYNPS steam dryer. The staff evaluated the licensee's calculational methodology to convert the design pressure loads obtained from the CFD and ACM analyses to the stress at various locations on the steam dryer, the combination of the calculated CFD and ACM stresses, the stress limits used in evaluating steam dryer integrity, and the margins to those limits. The staff also reviewed the information provided by the licensee for monitoring the loads exerted on the steam dryer during plant operation and overall dryer performance. In its CFD analysis, the licensee conducted a, Large Eddy Simulation (LES) of the upper portion of the VYNPS reactor pressure vessel (including the steam dryer) and MSLs. The licensee determined pressure loads from low frequencies up into the acoustic range based on CFD analyses. Upon filtering the CFD analysis based on frequency, the licensee predicted stresses of low magnitude in the VYNPS steam dryer dye to hydrodynamic loads having a frequency. content of less than 30 Hz. In Attachment 5 to Supplement 33 of its EPU request, the licensee indicated that it used the full CFD predicted stress (and not the filtered CFD stress) in the evaluation of the combined stress and the limit curve factors. The licensee estimated the uncertainty of the CFD analysis as 15% based on a previous analysis of a small pipe flow model, and used measurements of low frequency pressure loads on steam dryers at four other nuclear power plants to support this uncertainty estimate. The NRC staff reviewed the CFD analysis (including the electronic data file) of the fluid dynamic loads on the VYNPS steam dryer. The NRC staff determined that significant uncertainty surrounds the CFD predictions, and that the magnitude of this uncertainty was highly underestimated by the licensee. For example, the licensee did not perform sensitivity studies of the CFD analysis applied to VYNPS to obtain an understanding of the significance of specific assumptions in the analysis. The comparison of the Vermont Yankee CFD results to the measured low frequency pressure loads at four other nuclear power plants does not establish the uncertainty value for the VYNPS CFD analysis, because CFD analyses were not performed for those other plants and all but one of those plants contained a steam dryer with an improved design to reduce hydrodynamic loads. The plant with a similar design steam dryer to VYNPS provided one pressure measurement that was in the skirt area with low flow conditions. Based on its review at that point, the staff determined that the uncertainty assumed by the licensee in its determination of the loads from the CFD analysis of the VYNPS steam dryer was significantly underestimated. To address this concern, and to confirm the licensee's predictions regarding the hydrodynamic and acoustic loads on the steam dryer, a license condition will be added to the VYNPS Facility Operating License as shown in SE Section 3.17.3. The license condition provides requirements for monitoring, evaluating, and taking prompt action in response to potential adverse flow effects as a result of operation at EPU conditions. The licensee applied two different methods in its effort to validate the ACM used to calculate the acoustic pressure loads at high frequencies on the VYNPS steam dryer. In one method, the licensee used air tests conducted at the GE SMT facility to compare pressure loads calculated Docket No. 7195 Attachment 6-3 Page 4 of 12

by the ACM from steam line data to pressure measurements from a scale model steam dryer. In the second method, the licensee compared pressure sensor,data collected from the. instrumented steam dryer at the Quad Cities Unit 2 nuclear power plant during its power ascension to pressure loads calculated by the version of the ACM selected for application to the VYNPS steam dryer. The NRC staff determined that a number of uncertainties exist regarding the use of the SMT facility to validate the specific application of the ACM for the VYNPS steam dryer (including the relatively low flow provided by the SMT facility and the substantial deviation of the ACM predictions to SMT measurements). As a result, the staff focused on the licensee's use of the pressure sensor data obtained from the Quad Cities ýUnit 2 instrumented steam dryer to validate the ACM for application to VYNPS. At VYNPS, the licensee applied a version of the ACM that was used by Ekelon to assess the pressure loads on the steam dryer at Quad Cities Unit 2 at a power level of 790 megawatts electric (MWe) during EPU restart in May 2005. At Quad Cities Unit 2, Exelon revised the 790 MWe version of the ACM based on additional pressure sensor data collected from its instrumented steam dryer at 930 MWe. For VYNPS, Entergy developed an uncertainty estimate for the "790 MWe-version" of the ACM based on a comparison of the pressure loads calculated by the ACM to the measured pressure at 27 locations on the Quad Cities Unit 2 steam dryer. From its evaluation, the licensee estimated the uncertainty of the ACM as 100% of the calculated steam dryer pressure load. The NRC staff reviewed the.licensee's estimation of the uncertainty of the version of the ACM used at VYNPS, and determined the 100% uncertainty value to be insufficient to provide reasonable assurance in the calculation of the pressure loads on the VYNPS steam dryer. For example, Figure EMEB-B-18-1-6 on page 16 in Attachment 1 to Supplement 33 of the licensee's EPU request indicates that the root mean square (RMS) of the pressure load calculated by the ACM, combined with the 100% uncertainty estimate, underpredicts the measured RMS pressure at many of the 27 pressure sensor locations on the Quad Cities Unit 2 steam dryer. Further, Figures EMEB-B-18-4-1 to 27 indicate that the power spectral density (PSD) from the ACM-calculated loads, combined with the 100% uncertainty estimate, underpredicts the PSD from the measured pressure data at Quad Cities Unit 2 over a wide frequency range for many of the 27 pressure sensors. As a result, the NRC staff considers the uncertainty assumed by the licensee for the version of the ACM applied at VYNPS to be significantly underestimated. To address this concern, and to confirm the licensee's predictions regarding the hydrodynamic and acoustic pressure loads on the steam dryer, a license condition will be added to the VYNPS Facility Operating License as shown in SE Section 3.17.3. The license condition provides requirements for monitoring, evaluating, and taking prompt action in response to potential adverse flow effects as a result of operation at EPU conditions. At VYNPS, the licensee currently uses data from the MSL venturi instrument lines and one strain gage on each MSL to provide input to the ACM. The long venturi instrument lines and the lack of an array of strain gages at each MSL measurement location at VYNPS can result in significant uncertainty (over 100%) in the pressure input to the ACM. The NRC staff questioned the reliability of the ACM in calculating steam dryer pressure loads based on the large uncertainty associated with the MSL input data. To address the concerns with the uncertainty of the current MSL data used as input to the ACM, the licensee stated in the cover letter for Supplement 33 of its EPU request that it would install 32 additional strain gages on the MSL piping during the fall 2005 refueling outage (RFO) and would enhance the data acquisition system prior to EPU operation to reduce the measurement uncertainty associated with the ACM input. During the August 22-25, 2005, audit, the licensee indicated that the 32 additional strain Docket No. 7195 Attachment 6-3 Page 5 of 12

                                                 -45  -

gages would be installed as a set of four strain gages in a quadrantarray at two locations on each MSL to provide 8 independent inputs to the VYNPS ACM. In Attachment 5 to Supplement 26 of its EPU request, the licensee described its structural analysis of the VYNPS steam dryer for CFD and ACM pressure loads at CLTP conditions. In Attachment 5 to Supplement 33 of its EPU request, the licensee discussed its updated structural analysis of the steam dryer that includes the ACM results for CLTP conditions from Supplement 26 combined with CFD pressure loads predicted for EPU conditions at VYNPS. The ACM analysis uses MSL instrumentation to project the measured pressure fluctuations as pressure loads on the steam dryer for the specific power level at which the plant is operating, and does not predict steam dryer loads for higher power levels. The ANSYS FEM for the VYNPS steam dryer analysis included the dryer support ring, dryer hoods,, end plates, cover plates, upper dryer banks, cross beams, bottom support plates, tie bars, and gussets. In early 2005, the licensee identified the need to revise the FEM to model more accurately the connection of the gussets to the lower cover plate. The FEM used to evaluate steam dryer stress'from CFD loads was updated at that time. The licensee performed hand calculations to verify that the stress at the gusset to cover plate connection from the ACM loads was significantly less than the applicable stress limit. As part of determining the EPU steam dryer load definition, the licensee will update the FEM model used in the ACM analysis to reflect the as-built connection of the gussets to the cover plate. The licensee evaluated the dynamic structural response of the steam dryer to applied pressure fluctuations from acoustic loading using a time history method with modal superposition. The licensee, performed a sensitivity assessment by varying the time interval between the pressure time steps by 10% (equivalent to peak broadening in the response spectrum analysis method). The licensee assigned an uncertainty to the stress amplitude of 20% due to load/response frequency uncertainty based on these shifted frequency analyses. However, the licensee did not include potential increased stress resulting from peak loading frequencies aligning with the dryer resonance frequencies in its analysis. For the fatigue stress evaluation, the licensee determined the peak stress for various locations on the VYNPS steam dryer by combining the stresses calculated from the CFD and ACM analyses by the SRSS method, and then multiplying the combined stress by applicable weld concentration and size factors. The licensee applied the acoustic and CFD uncertainties to calculate an uncertainty value for the limit curve factor used to monitor steam dryer performance. For the ASME load case assessments, the licensee increased the acoustic loading stress by a 130% uncertainty value and the CFD loading stress by a 16% uncertainty value, and combined these stresses by the SRSS method. The licensee then compared the results of these stress analyses to the applicable ASME allowable stress limits to demonstrate available structural margin in the VYNPS steam dryer. In Attachment 2 to Supplement 33, the licensee provided the results of its analysis of the dryer skirt indicating low acoustic loading stress for that region of the VYNPS steam dryer. Based on the ASME fatigue stress limit, the licensee calculated an allowable limit curve over the frequency spectra using the CFD analysis for low frequency loads and the ACM analysis for the high frequency loads with the current MSL data input, including the consideration of uncertainties. The NRC staff reviewed the method used by the licensee to calculate the stress at various locations on the VYNPS steam dryer based on the pressure loads predicted by the CFD and ACM analyses. As a result of the uncertainties associated with the CFD and ACM analyses and MSL input data, the NRC staff indicated during the audit on August 22-25, 2005, Docket No. 7195 Attachment 6-3 Page 6 of 12

that it was important to demonstrate that the structural integrity of the steam dryer would not be challenged if the actual loads on the steam dryer reached the limit curve. In Attachment 5 to Supplement 33 of its EPU request, the licensee provided its assessment of the limit curve relative to the fatigue stress limit to demonstrate that, if the limit curve is not exceeded, the structural integrity of the VYNPS steam dryer will be assured. In its assessment, the licensee calculated the most limiting stress location as the (( 1] with a stress of (( )) psi based on the CFD analysis at EPU conditions and a stress of (( )) psi based on the ACM analysis at CLTP conditions. As these stresses are associated with independent low and high frequency pressure loads, respectively, the combined peak stress for this location on the VYNPS steam dryer is calculated by the SRSS method to be (( )) psi. The licensee established a limit curve that would provide for an SRSS combination of CFD and ACM stress at the most limiting steam dryer location of 7393 psi. Therefore, the limit curve stress will provide considerable margin to the ASME fatigue limit stress of 13,600 psi. As discussed below, in accordance with the license condition discussed in SE Section 3.17.3, the licensee will provide its limit curve as part of the startup test procedure for VYNPS to the NRC staff prior to exceeding CLTP. In Attachment 6 to Supplement 33 of its EPU request, the licensee describes its updated Steam Dryer Monitoring Plan (SDMP) for monitoring and evaluating the performance of the VYNPS steam dryer during power ascension testing and operation above CLTP to full EPU conditions to verify acceptable steam dryer performance. The licensee defines unacceptable steam dryer performance as a condition that could challeng steam. dryer structural integrity and result in the generation of loose parts, cracks or tears in the dryer that-result in excessive moisture carryover. The licensee proposed a license condition for steam dryer monitoring to require operational surveillances as well a-s visual inspections of the steam dryer at specific scheduled RFOs following achievement of full uprate conditions as shown in SE Section 3.17.3. The .licensee stated that power ascension above CLTP would be conducted in 2.5% power steps and 5% power plateaus. The power ascension will include hold points at each 2.5% step and 5% plateau. The licensee stated that the maximum power increase would not exceed a nominal 5% power in a 24-hour period. The SDMP specifies that moisture carryover will be determined every 24 hours; MSL pressure data from strain gages will be obtained hourly when initially increasing power above a previously attained level and at least once every 2.5% power step above CLTP; and MSL pressure data from pressure transducers will be collected at least once every 2.5% power step above CLTP and within 1 hour after achieving every 2.5% power step above CLTP. The SDMP allows relaxed monitoring if the surveillance requirements are met at a power step, but requires a power reduction if a surveillance is not accomplished within the specified time intervals. In addition, the SDMP indicates that plant data which may be indicative of off-normal dryer performance will be monitored during power ascension (e.g., steam flow, feed flow, etc.). The SDMP establishes criteria for verifying acceptable steam dryer performance at VYNPS using moisture carryover and MSL pressure data. The performance criteria are specified as Level 2 based on maintaining less than (or equal to) 80% of the ASME allowable alternating stress at 101 cycles (i.e., 10,880 psi) and Level 1 based on maintaining the ASME allowable alternating stress at 1011 cycles (i.e., 13,600 psi). The Level 2 steam dryer performance criteria are (1) moisture carryover exceeds 0.1%; (2) moisture carryover exceeds 0.1% and increases by more than 50% over the average of the three previous measurements taken at greater than 1593 MWt; and (3) pressure data exceed the Level 2 spectra. If any of the Level 2 steam dryer performance criteria are exceeded, the SDMP specifies that (1) reactor power ascension be Docket No. 7195 Attachment 6-3 Page 7 of 12

promptly suspended until an engineering evaluation concludes that further power aýcension is justified; and (2) before resuming reactor power ascension, the steam dryer performance data shall be reviewed as part of an engineering evaluation to assess whether further power ascension can be made without exceeding the Level 1 criteria. The Level 1 steam dryer performance criteria are (1) moisture carryover exceeds 0.35%; and (2) pressure data exceed Level 1 spectra. If either of the Level 1 steam dryer performance criteria is exceeded, the SDMP specifies that the licensee will: (1). Promptly initiate a reactor power reduction and achieve a previously acceptable power level (i.e., reduce power to a previous step level) within 2 hours, unless an engineering evaluation concludes that continued power operation or power ascension is acceptable. (2) Within 24 hours, re-measure moisture carryover and perform an engineering evaluation of steam dryer structural integrity. If the results of the evaluation of dryer structural integrity do not support continued'plant operation, the reactor shall be placed in a hot shutdown condition within tt~e following 24 hours. Ifthe results of the engineering evaluation support continued power operation, implement steps (3) and (4) below. (3) If the results of the engineering evaluation support continued power operation, reduce further power ascension step and plateau levels to nominal increases of 1.25% and 2.5% of, CLTP, respe(tively, for any additional power ascension. (4) Within 30 days, use the transient pressure data to calculate the steam dryer-fatigue usage to demonstrate that continued power operation is acceptable. The SDMP also specifies that, if the steam dryer performance criteria are exceeded, the following actions will be taken depending on the criteria exceeded: (1) Either suspend reactor power ascension (Level 2 Acceptance Criteria) or reduce reactor power (Level 1 Acceptance Criteria), initiate a Condition Report, and evaluate the cause of any exceedance of the performance criteria. (2) Prior to increasing reactor thermal power to a level higher than any previously attained, the plant conditions relevant to steam dryer integrity and associated evaluation results shall be reviewed by the on-site safety review committee, and a recommendation shall be made to the General Manager, Plant Operations prior to increasing power for each 5% power plateau. (3) Strain gage pressure and moisture carryover data collected at each 5% power plateau will be made available to the NRC through its resident inspector. (4) Each initial increase in reactor thermal power to the next higher 5% power plateau above 100% CLTP must be authorized by the General Manager, Plant Operations. In addition, the SDMP states that other reactor operational parameters that may be influenced by steam dryer integrity (e.g., steam flow distribution between the individual steam lines) will be Docket No. 7195 Attachment 6-3 Page 8 of 12

monitored with the intent of detecting structural degradation of the steam dryer during plant operation (e.g., flow distribution between individual MSLs). Plant procedures will control the enhanced monitoring of selected plant parameters. The SDMP states that the results of visual inspections of the steam dryer conducted during the next three RFOs shall be reported to the NRC staff within 60 days following startup from the respective RFO. The SDMP also states that its results shall be submitted to the NRC staff in a report within 60 days following completion of all EPU power ascension testing. In addition, the final full EPU power performance criteria spectra (limit curve),will be submitted to the NRC staff within 120 days. As long-term actions, the SDMP states that the VYNPS steam dryer will be inspected during RFOs scheduled for fall 2005, spring 2007, fall 2008, and spring 2010, according to the recommendations of GE Services Information Letter (SIL) No. 644, Revision 1 (November 9, 2004). The SDMP also indicates that, following completion of EPU power ascension testing, moisture carryover measurements will continue to be made periodically, and other plant operational parameters that may be affected by steam dryer structural integrity will continue to be monitored, in accordance with GE SIL 644 and plant procedures. The SDMP notes that temporarily installed pressure monitoring sensors and strain gages may be removed from service following achievement of one operating cycle after issuance of the EPU license amendment and satisfaction of the license condition requirements for steam dryer inspections. .In Attachment 1 to Supplement 32 to its EPU request, the licensee modified its commitment to perform visual inspections of the steam dryer at VYNPS. In particular, the licensee describes its plan to perform a visual inspection during the fall 2005 RFO of the steam dryer modification, flaws left "as-is," and the repair made during the last RFO. The licensee indicates that this inspection plan satisfies recommendations A.1.c and A.l.d in GE SIL 644, Revision 1. The licensee also discusses its plan to conduct a visual inspection of all accessible, susceptible locations of the steam dryer during each of the three RFOs, beginning with RFO-26 (i.e., spring 2007) to satisfy recommendation B.2 in SIL 644, Revision 1. The licensee lists this steam dryer inspection plan as a regulatory commitment in Attachment 10 to Supplement 32. In the cover letter for Supplement 33 of its EPU request, the licensee states that several actions will be taken with respect to providing confidence in the capability of the steam dryer at VYNPS to maintain its structural integrity under EPU conditions. In Attachment 1 to Supplement 36, Entergy specified those planned actions as part of a proposed license condition. The proposed license condition is shown in SE Section 3.17.3. The actions include: (1) The licensee will install 32 additional strain gages on the main steam piping during the fall 2005 RFO and will enhance the data acquisition system prior to EPU operation in order to reduce the measurement uncertainty associated with the ACM. (2) In the event that acoustic signals are identified that challenge the limit curve during EPU power ascension, the licensee will evaluate dryer loads and re-establish the limit curve based on the new strain gage data, and will perform a frequency specific assessment of ACM uncertainty at the acoustic signal frequency. Docket No. 7195 Attachment 6-3 Page 9 of 12

(3) After reaching 120% of CLTP, the licensee will obtain measuremenfs from the MSL strain gages and establish the VYNPS dryer flow-induced vibration load fatigue margin, update the dryer stress report, and re-establish the SDMP limit curve with the updated ACM load definition and revised instrument uncertainty, which will be provided to the NRC staff. (4) During power ascension, if an engineering evaluation is required in accordance with the SDMP, the licensee will perform the structural analysis to address frequency uncertainties tip to +/-10% and assure that peak responses that fall within this uncertainty band are addressed. (5) The licensee will revise the SDMP to reflect long-term monitoring of plant parameters potentially indicative of a dryer failure; to reflect consistency of the VYNPS steam dryer inspection program with SIL 644, Revision 1; and to identify the NRR Project Manager for VYNPS as the point of contact for providing SDMP information during power ascension. (6) The licensee will submit the final EPU VYNPS steam dryer load definition to the NRC upon completion of the power ascension test program. (7) The licensee will submit the flow-induced vibration related portions of the EPU startup test procedure, including the methodology for updating the limit curve, prior to power ascension. In Attachment 6 to Supplement 33 of its EPU request, the licensee proposed a license condition for implementation of the VYNPS SDMP. The proposed license condition was subsequently superceded by Supplement 36 of the EPU request. The proposed license condition is shown in. SE .Section 3.17.3. of theNRC The staff has reviewed the information provided by the licensee in support of its analysis structural integrity of the VYNPS steam dryer under EPU conditions, and for monitoring steam dryer loads and performance during plant operation. Although significant uncertainty exists regarding the licensee's method for calculating specific stress values on the VYNPS steam dryer from its CFD and ACM analyses, the licensee's current MSL instrumentation suggests minimal excitation of the pressure frequency spectra in the MSLs at CLTP conditions. As a result, the staff finds that the licensee has demonstrated that the flow-induced stress imposed on the VYNPS steam dryer at CLTP conditions is within the,fatigue stress limits provided in the ASME Code. However, the available margin to those stress limits is not readily verifiable. Therefore, the NRC staff considers the licensee's planned actions specified in Supplement 33 of its EPU request, and included in the proposed license condition in Supplement 36, to be an important part of the licensee's effort to provide confidence that the structural integrity of the steam dryer will be maintained during EPU operation. For example, the staff considers the use of the more accurate MSL strain gages to be installed for monitoring pressure fluctuations in the MSLs to be necessary in light of the large uncertainty in the current MSL instrumentation that provides input to the ACM analysis. The staff considers the selection of the new MSL instrumentation in terms of its sensitivity and signal-to-noise ratio to be important to its acceptability. The staff also considers it important to consider whether any acoustic sources might exist between the MSL strain gage locations. Further, the staff agrees with the importance of evaluating the peak frequencies within the +/-10% frequency range when Docket No. 7195 Attachment 6-3 Page 10 of 12

the licensee re-evaluates the steam dryer loads if MSL strain gage data exceed the limit curve, or following achievement of EPU conditions, as part of establishing a new limit curve. During the licensee's evaluation of the results of the inspection of the VYNPS steam dryer to be conducted in the fall of 2005, the predictions of low stress (including in the skirt region) need to be compared to actual operating experience with the VYNPS steam dryer. The staff also considers the requirements specified by the licensee in the proposed license condition to be appropriate for establishing and implementing the SDMP at VYNPS. In light of the large uncertainties in the CFD and ACM analyses and the fact that the ACM analysis has calculated the steam dryer pressure loads only at CLTP, the NRC staff determined that the licensee needs to closely monitor MSL strain gage data and other plant data as the reactor power is raised at VYNPS such that the ACM loads can be calculated at the increased power level to verify that the structural limits for the steam dryer are not reached. For example, the staff concluded that the new 32 MSL strain gages need to be monitored frequently during power ascension above CLTP for increasing pressure fluctuations in the steam lines. Hold points need to be established at 105%, 110%, and 115% of CLTP to collect plant data, conduct plant inspections and walkdowns, and evaluate the plant data for steam dryer performance. The time period for each hold point will need to be sufficient to complete all activities specified in the startup test procedure for the applicable hold point. Sufficient information and time will need to be provided to the NRC staff to determine whether any safety concerns exist prior to increasing power above each hold point. If any frequency peak from the MSL strain gage data exceeds the limit curve established by the licensee prior to operation above CLTP, the unit needs to be returned to a power level where the limit curve is not exceeded. The licensee would then resolve the uncertainties in the steam dryer analysis prior to further increases in reactor power. In the subsequent engineering evaluation, peak responses that fall within the

+/-10% frequency uncertainty band need to be considered as part of an adequate structural analysis. Further, the potential effect of the skirt in the steam dryer FEM on the stresses- in the steam dryer components needs to be addressed. In addition to evaluating the MSL strain gage data, reactor pressure vessel water level instrumentation or MSL piping accelerometers need to be monitored frequently to help identify any resonance frequencies not captured by the MSL strain gage data and ACM analysis. If resonance frequencies are identified as increasing significantly above nominal levels established at CLTP conditions, power ascension needs to be stopped until an evaluation of continued steam dryer integrity is performed to demonstrate that no safety concerns exist. Within a reasonable time period following issuance of the EPU license amendment, the uncertainties in the steam dryer analysis need to be resolved to avoid long-term fatigue concerns with the steam dryer. In response to an NRC letter dated October 12, 2005, Entergy submitted a proposed license condition in Attachment 1 to Supplement 36 of its EPU application that.addresses the NRC staff findings discussed above.

The proposed license condition is shown in SE Section 3.17.3. The NRC staff considers the development of an adequate EPU startup test procedure to be a significant action in confirming the safe operation of VYNPS during EPU conditions. The staff has determined that the EPU startup test procedure needs to include (a) the stress limit curve to be applied for evaluating steam dryer performance; (b) specific hold points and their duration during EPU power ascension; (c) activities to be accomplished during hold points; (d) plant parameters to be monitored; (e) inspections and walkdowns to be conducted for steam, FW, and condensate systems and components during the hold points; (f) methods to be used to trend plant parameters; (g) acceptance criteria for monitoring and trending plant parameters, and conducting the walkdowns and inspections; (h) actions to be taken if acceptance criteria Docket No. 7195 Attachment 6-3 Page 11 of 12

are not satisfied; and (i) verification of the completion of commitments and planned actions specified in the EPU application and all, supplements to the application in support of the EPU request prior to power increase above CLTP. While the licensee indicates that plant parameters will be monitored to provide information on steam dryer performance, the staff also, considers it important for additional steam dryer loading information to be obtained for qualitative evaluation from the reactor pressure vessel water level instrumentation or MSL piping accelerometers in light of the inadequacy of the ACM in calculating low frequency pressure loads on the steam dryer. While the SDMP indicates that other plant parameters (such as steam flow distribution between MSLs) will be monitored, the staff also considers it important for the frequency of such monitoring, acceptance criteria, and actions if those criteria are not satisfied, to be specified in the startup test procedure. In response to an NRC letter dated October 12, 2005, Entergy submitted a proposed license condition in Attachment 1 to Supplement 36 of its EPU application. The staff has determined that this proposed license condition addresses the NRC staff findings discussed above. The proposed license condition is shown in SE Section 3.17.3.'- Prior to power ascension above CLTP and during the power ascension, the NRC staff has determined that sufficient time needs to be available during the hold points to allow the licensee to present plant information on potential adverse flow effects on the steam dryer (and other plant equipment) to the NRC staff for a determination of whether any safety concerns exist with power ascension. In Attachment 2 to Supplement 36 of its EPU request, Entergy submitted a regulatory commitment that addresses the NRC staff.findings discussed above. As shown in SE Section 4.0 (Item No. 25), Entergy will provide information on plant data, evaluations, walkdowns, inspections, and procedures associated with the individual requirements of the license condition (pertaining to potential adverse flow effects) to the NRC staff prior to increasing power above 1593 MWt or each specified hold point, as applicable. If any safety concerns are identified during the NRC staff review of the provided information, Entergy will not increase power above 1593 MWt or the applicable hold point, and the specific requirements in the license condition will not be satisfied. The NRC staff considers that this commitment provides appropriate interaction between the licensee and the staff prior to and during power ascension above CLTP conditions. 2.2.6.2.2 Steam. Feedwater, and Condensate Systems and Components In Attachment 1 to Supplement 15 (September 23, 2004) of its EPU request, the licensee stated that the VYNPS piping steady state vibration program for EPU power ascension testing follows the guidance in Part 3 of the ASME OM-S/G-2000 standard (ASME OM-3). The program assesses the FIV levels of selected piping systems that are expected to experience increased flow during EPU conditions. The licensee stated that vibration data will be taken at approximately 2.5% power increments above CLTP and will be evaluated for acceptability. For example, the MS and FW piping located in the drywell which is inaccessible during plant operation will be monitored for vibration levels using direct mounted accelerometers with acceptance criteria based on guidance in ASME OM-3. The FW regulator valves and attached FW piping located downstream of the reactor feed pumps will be monitored with a hand-held vibration meter. If vibration levels for these components increase significantly, the licensee will further evaluate the affected components. Also in Attachment 1 to Supplement 15 of its EPU request, the licensee stated that it will employ visual monitoring during EPU power ascension testing to determine if significant Docket No. 7195 Attachment 6-3 Page 12 of 12

Entergy Power Ascension Test Recalculations Page 2 of 2 Subject; Entergy PowerAscension Test Recalculations I was asked to'describe how Entergy is analyzing the acoustical noise identified at the 5% power-increase in order to proceed to the next 5% step up. I know this is complicated and I am happy to try to explain more if necessary! Entergy has a series of limit curves based on acoustical sensor locations on its four main steam lines. For each location, these curves define the acoustical noise acceptability -limit. The curves are created from complex calculations based on. stress limits of the steam dryer, the known acoustical signature of the steam lines, benchmarked steam dryer performance from Quad Cities, and various safety margins. Using the new acoustical signature from the 105% readings and newer industry data, the curves were recalculated for the next 5% step up. The new acoustical signature input has the effect of redistributing the limiting steam dryer stress according to that newly expected acoustical signature. This means there will be more "room" (i.e., a higher limit) for the frequency that was unexpectedly high at the 105%, and less room at certain other frequencies that proved not to be active at the 105% level.. We derive some confidence that NRC specialists - PHD consultants hired by NRC - will reviewand concur with the new analytical curves before the next step up. The earliest time for the next step up is this Sunday, March 26. it seems possible to me that additional power step-ups may reveal more frequency surprises and cause yet additional recalcuations and a redistribution of steam dryer stress vs. frequency.

C-C) UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 May 5, 2006 Mr. Marvin Moriarty, Regional Director. Northeast Regional Office U.S. Fish and Wildlife Service 300 Westgate Center Drive Hadley, MA 01035-9589

SUBJECT:

REQUEST FOR LIST OF PROTECTED SPECIES WITHIN THE AREA UNDER EVALUATION FOR THE VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION REVIEW

Dear Mr. Moriarty:

The U.S. Nuclear Regulatory Commission (NRC) is reviewing an, application submitted by Entergy Nuclear Operations, Inc. (Entergy) for the renewal of the operating license for the Vermont Yankee Nuclear Power Station (VYNPS). VYNPS is located in the town of Vernon, Vermont, in Windham County on the west shore of the Connecticut River immediately upstream of the Vernon Hydroelectric Station. As part bf the review of the license renewal application (LRA), the NRC is preparing a Supplemental Environmental Impact Statement (SEIS) under the provisions of Title 10 of the Code of FederalRegulations Part 51 (10 CFR Part 51), the NRC regu'lation that implements the National Environmental Policy Act (NEPA) of 1969. The SEIS includes an analysis of pertinent environmental issues, including endangered or threatened species and impacts to fish and wildlife. This letter is being submitted under the provisions of the Endangered Species Act of 1973, as amended, and the Fish and Wildlife Coordination Act of 1934, as amended. The proposed action would include the use and continued maintenance of existing plant facilities and transmission lines. VYNPS stated that no major refurbishment activities have been identified as necessary to support the continued operation of VYNPS beyond the end of the existing operating license term. VYNPS is situated on approximately 125 acres of land on the west shore of the Connecticut River 0.75 miles upstream of the Vernon Hydroelectric Station. This section of the river is known as Vernon Pool. The areas adjacent to the station are primarily farm and pasture lands. The area within a five mile radius is predominantly rural with the exception of a portion of the town of Brattleboro, Vermont, and the town of Hinsdale, New Hampshire. Between 75 percent and 80 percent of the area within five miles of the station is wooded. The remainder is occupied by farms and small industries. Enclosure 1 shows the layout of the general area near the VYNPS site and Enclosure 2 presents an overview of the site location. NRC 50-271-LR ASLBP 06-849-03-LR DPS-4 8 Pages

M. Moriarty -2.- The VYNPS utilizes a once-through cooling system and mechanical draft cooling towers to remove waste heat from the condensers. The three circulating water pumps are located in the enclosed intake structure at the river bank. Water from the main condensers is returned to the discharge structure where it is either discharged through an aerating structure to the river oris diverted to the cooling towers. Water circulated through the towers may be either discharged through the aerating structure to the river or recirculated in a closed loop path to the intake structure, or a combination of both, known as hybrid cycle mode. The discharge path is manually selected by the operator and is contingent upon seasonal variation in environmental parameters. The only transmission lines considered to be in scope for the review are located inside the 125 acre plant site. These transmission lines were constructed to connect VYNPS to the New England transmission grid. The transmission lines exiting the switchyards are part of the New England transmission grid that was constructed to supply purchased power to the State of Vermont. The New England transmission grid is not considered to be in scope of the license renewal review. To support the SEIS preparation process and to ensure comp!iance with Section 7 of the Endangered Species Act, the NRC requests information on Federally listed, proposed, and candidate species and critical habitat that may be in the vicinity of the VYNPS site. In addition, please provide any information you consider appropriate under the provisions of the Fish and Wildlife Coordination Act. From May 23-25, 2006, the NRC staff plans tb conduct a site audit at the VYNPS. On June. 7, 2006, the NRC staff plans to hold two public NEPA scoping meetings at the Latchis Theatre, 50 Main Street, Brattleboro, Vermont 05301. The first session will convene at 1:30 p.m. and will continue until 4:30 p.m., as necessary. The second session will convene at 7:00 p.m., with a repeat of the overview portions of the meeting, and will continue until 10:00 p.m., as necessary. In addition to the environmental scoping meeting described above, the NRC will hold an informal open house at the Quality Inn & Suites, 1380 Putney Road, Brattleboro, Vermont 05301, on Tuesday, June 6, 2006, from 2:00 p.m.-8:00 p.m., as necessary. You and your staff are invited to attend both the site audit and the public meetings. Your office will receive a copy of the draft SEIS along with a request for comments. The anticipated publication date for the draft SEIS is December 2006.

14. Moriarty If you have any questions concerning the NRC staff review of this LRA, please contact Mr. Richard L. Emch Jr., Senior Environmental Project Manager at 301-415-1590 or RLEC.nrc.aov.

REQUEST FOR LIST OF PROTECTED SPECIES AND ESSENTIAL FISH HABITAT WITHIN THE AREA UNDER EVALUATION FOR THE VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION REVIEW

Dear Ms. Kurkul:

The U.S. Nuclear Regulatory Commission (NRC) is reviewing an application submitted by Entergy Nuclear Operations, Inc. (Entergy) for the renewal of the operating license for the Vermont Yankee Nuclear Power Station (VYNPS). VYNPS is located in the town of Vernon, Vermont, in Windham County on the west share of the Connecticut River. As part of the review of the license renewal application (LRA), the NRC is preparing a Supplemental Environmental Impact Statement (SEIS) under the provisions of Title 10 of the Code of FederalRegulations Part 51 (10 CFR Part 51), the NRC regulation that implements the National Environmental Policy Act (NEPA) of 1969. The SEIS includes an analysis of pertinent environmental issues, including endangered or threatened species and impacts to marine resources and habitat. This letter is being submitted under the provisions of the Endangered Species Act of 1973, as amended, and the Fish and Wildlife Coordination Act-of 1934, as amended, and the Magnuson-Stevens Fishery Conservation and Management Act. The proposed action would include the use and continued maintenance of existing plant facilities and transmission lines. VYNPS stated that no major refurbishment activities have been identified as necessary to support the continued operation of VYNPS beyond the end of the existing operating license term. VYNPS is situated on approximately 125 acres of land on the west shore of the Connecticut River 0.75 miles upstream of the Vernon Hydroelectric Station. This section of the river is known as Vernon Pool. The areas adjacent to the station are primarily farm and pasture lands. The area within a five mile radius is predominantly rural with the exception of a portion of the town of Brattleboro, Vermont, and the town of Hinsdale, New Hampshire. Between 75 percent and 80 percent of the area within five miles of the station is wooded. The remainder is occupied by farms and small industries. Enclosure 1 shows the layout of the general area near the VYNPS site and Enclosure 2 presents an overview of the site location. NRC 50-271-LR ASLBP 0 6 -849-03-LR DPS-5 8 Pages

P. Kurkul The VYNPS utilizes a once-througlh cooling system'and mechanical draft cooling towers to remove waste heat from the condensers. The three circulating water pumps are located in the enclosed intake structure at the river bank. Water from the main condensers is returned to the discharge structure where it is either discharged through an aerating structure to the river or is diverted to the cooling towers. Water circulated through the towers may be either discharged through the aerating structure to the river or recirculated in a closed loop path to the intake structure, or a combination of both, known as hybrid cycle mode. The discharge path is manually selected by the operator and, is contingent upon seasonal variation in environmental parameters. The only transmission lines considered to be in scope for the review are located inside the 125 acre plant site. These transmission lines were constructed to connect VYNPS to the New England transmission grid. The transmission lines exiting the switchyards are part of the New England transmission grid that was constructed to supply purchased power to the State of Vermont. The New England transmission grid is not considered to be in scope of the license renewal review. To support the SEIS preparation process and to ensure compliance with Section 7 of the Endangered Species Act, the NRC requests information on Federally listed, proposed and candidate species, and critical habitat under toie jurisdiction of the National Marine Fisheries Service that may be in the vicinity of the VYNPS site. In addition, please provide any information you consider appropriate under the provisions of the Fish and Wildlife Coordination Act. Also in support of the SEIS preparation and to ensure compliance with Section 305 of the Magnuson-Stevens Fishery Conservation and Management Act, the NRC requests a list of essential fish habitat that has been designated in the vicinity of the VYNPS site. From May 23-25, 2006, the NRC staff plans to conduct a site audit at the VYNPS. On June 7, 2006, the NRC staff plans to hold two public NEPA scoping meetings at the Latchis Theatre, 50 Main Street, Brattleboro, Vermont 05301. The first session will convene at 1:30 p.m. and will continue until 4:30 p.m., as necessary. The second session will convene at 7:00 p.m., with a repeat of the overview portions of the meeting, and will continue until 10:00 p.m., as necessary. In addition to the environmental scoping meeting described above, the NRC will hold an informal open house at the Quality Inn & Suites, 1380 Putney Road, Brattleboro, Vermont 05301, on Tuesday, June 6, 2006, from 2:00-8:00 p.m., as necessary. You and your staff are invited to attend both the site audit and the public meetings. Your office will receive a copy of the draft SEIS along with a request for comments. The anticipated publication date for the draft SEIS is December 2006.

P. Kurkul If you have any questions concerning the NRC staff review of this LRA, please contact Mr. Richard L. Emch Jr., Senior Environmental Project Manager at 301-415-1590 or RLE(cDnrc. av Sincerely, Rani Franovich, Branch Chief Environmental Branch B Division of License Renewal Office of Nuclear Reactor Regulation Docket .No. 50-271

AMENDED REQUEST FOR LIST OF PROTECTED SPECIES WITHIN THE AREA UNDER EVALUATION FOR THE VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION REVIEW

Dear Mr. Moriarty:

In a letter dated May 5, 2006, the U.S. Nuclear Regulatory Comrmission (NRC) staff requested information on Federally listed, proposed, and candidate species and critical habitat that might be in the vicinity of the Vermont Yankee Nuclear Power Station (VYNPS) site. In that letter the staff indicated that the only area considered to be in scope for the license renewal environmental review was the 125 acre plant site. The letter further stated that no transmission lines were considered to be in scope for the review. After obtaining additional information related to the construction of the transmission lines, the staff has reconsidered its initial position and come to the conclusion that two transmission lines exiting the VYNPS will be considered within the scope of the environmental review. The reconsidered transmission lines are the 115 Kv transmission lines from VYNPS to the Coolidge Substation in Vermont (51 miles) and from VYNPS to the Chestnut Hill Substation in New Hampshire (2 miles). To support the Supplemental Environmental Impact Statement (SEIS) preparation process and to ensure compliance with Section 7 of the Endangered Species Act of 1973, the NRC requests information on Federally listed, proposed, and candidate species and critical habitat that might be in the vicinity of the VYNPS site and the previously mentioned transmission lines. In addition, please provide any information you consider appropriate under the provisions of the Fish and Wildlife Coordination Act. CD, t o '- NRC 50-27[-LR C: C ASLBP 06-849-03-LR DPS-6 9 Pages
