Entergy Letter dated March 28, 2003, "Submittal of Second Reactor Vessel Surveillance Capsule Report"
Dear Sir or Madam:
By letter (Reference 1), Entergy Operations, Inc. (Entergy) proposed a change to the Waterford Steam Electric Station, Unit 3 (Waterford 3) Operating License and Technical Specifications to increase the units rated thermal power level from 3441 megawatts thermal (MWt) to 3716 MWt.
By letter (Reference 2), the Nuclear Regulatory Commission (NRC) staff requested additional information (RAI) related to two review areas. The first set of questions (three) addresses meteorological data and atmospheric dispersion calculations and Entergy's response to these questions is contained in Attachment 1. Electronic files associated with the answers in can be found on the enclosed compact disc submitted with this letter. The second set of questions (seven) addresses steam generator integrity and chemical engineering and Entergy's response to these questions is contained in Attachment 2. requests NRC approval to implement the revised reactor vessel surveillance capsule removal schedule submitted to the NRC in Reference 3.
This letter contains one new commitment as identified in Attachment 4. The original no significant hazards consideration included in Reference 1 is not affected by any information contained in this supplemental letter.

Attachment I To W3FI -2004-0017 Response to Request for Additional Information Meteorological Data and Atmospheric Dispersion Calculations
Attachment I to W3FI-2004-0017 Page 1 of 48 Response to Request for Additional Information Meteorological Data and Atmospheric Dispersion Calculations Question 1:
Please provide an electronic copy of the hourly meteorological data used to calculate the control room atmospheric dispersion factors as well as the joint frequency distributions used in the PAVAN calculations. The hourly data should be provided either in the format specified in Appendix A to Section 2.7, "Meteorology and Air Quality," of NUREG-1 555, 'Environmental Standard Review Plan,' or in the ARCON96 format described in NUREG/CR-6331, "Atmospheric Relative Concentrations in Building Wakes." Data may be provided in compressed form, but a method to decompress the data should be provided. What are the heights at which the data were measured? Was stability class determined as a function of delta-temperature? If so, which delta-temperature measurement heights were used and how were these measurements converted to stability class (e.g., converted to 0C/100 meters for comparison to Regulatory Guide (RG) 1.23, uOnsite Meteorological Programs" criteria)? What are the units of wind speed (e.g., miles per hour, meters per second)? In generating the hourly meteorological files used as input to ARCON96, did the valid wind direction values range from 1 to 3600 and were invalid data designated by completely filling the field for that parameter with 9's? Page 2.13-12 states that data were obtained from "each of the meteorological towers." Which towers were used to provide what data and how were the data combined in the hourly data files and in the joint frequency distributions used to make the relative concentration (X/Q) calculations?
Response 1:
Data files of the hourly meteorological data for the years 1997 through 2001 used to calculate the control room atmospheric dispersion factors are provided on the enclosed compact disc in ARCON96 format with the following file names:
File Name Description W97.MET Meteorological Data for 1997 W98.MET Meteorological Data for 1998 W99.MET Meteorological Data for 1999 WOO.MET Meteorological Data for 2000 WO1.MET Meteorological Data for 2001 The following joint frequency distributions (JFD) were obtained from the Waterford 3 'Annual Meteorological Monitoring Program Report" for the years 1997 through 2001.

0 936 Number of calms for G Stability: 4 Total valid hours for all stabilities = 8760 Total invalid hours for all stabilities = 0 to W3FI-2004-0017 Page 37 of 48 The above joint frequency distributions were combined to produce joint frequency distributions for a representative year for use in the PAVAN computer code.
Data is measured at 10 meter (lower level instrument) and 60 meter (upper level instrument) levels.
The stability class was determined as a function of delta-temperature from the 10 meter and 60 meter instrument measurements. The delta-temperature measurements based on a 50 meter change in height were converted to units of 0C/1 00 meter to determine the stability class. Stability classes were based on the classification system given in Regulatory Guide 1.23, "Onsite Meteorological Programs."
The units of wind speed are meters/second.
The valid wind directions ranged from 1° to 3600. The data was reviewed for wind directions greater than 3600 and any data above 3600 was corrected by subtracting 3600. All invalid data was identified by completely filling the field with 9's.
In general, the data used in the atmospheric dispersion calculations was provided by the primary meteorological tower. However, if the primary meteorological tower was out of service, the backup (secondary) meteorological tower was used as the data source.
(Reference technical specification figure 5.1-1 for approximate locations of the primary and secondary meteorological towers.) Separate data files are generated for both the primary and backup towers with the composite data file representing the best available data set. The data source for each hourly averaged data parameter is provided in the composite yearly meteorological data file. This composite yearly meteorological data files were used to generate the ARCON96 format data files.
Question 2:
For control room X/Q calculations, please provide a figure or figures showing the assumed locations of release and control room intakes with respect to the overall plant layout. Provide a quantitative list of all inputs used in estimating the postulated transport of effluents from each of the release locations to the intakes. A copy of the ARCON96 printouts is acceptable to show inputs. Was the physical height of the release location assumed or was an effective release height used in any calculation? If flow rates were assumed when making X/Q calculations, were they based on technical specification (TS) values? If more than one release to the environment or more than one transport scenario could occur (e.g., loss-of-offsite power and non-loss of site power, single failure), were comparative XQ calculations made to ensure consideration of the limiting dose?
X/Q values have been calculated for two intakes. Were the X/Q values used in the dose assessment based upon the more limiting release and intake pair, upon a weighted average (e.g., as described in RG 1.194, "Atmospheric Relative Concentrations for Control Room Radiological Habitability Assessments at Nuclear Power Plants,") or some other criteria? If weighted values were used, describe how estimates were calculated, including inflow rates of each intake and any reduction factors (e.g., due to automatic selection of the least to W3F1 -2004-0017 Page 38 of 48 contaminated outside air intake). Provide justification for the use of any reduction factors. If applicable, are control room air intake inflow rates based upon measured values? Confirm that each of the control room intakes meet applicable design criteria of an engineered safeguards feature, including single-failure criterion, missile protection, seismic criteria, and operability TS to merit reduction credit as dual intakes.
Response 2:
See diagram at the end of Attachment 1 for the approximate locations of the assumed release points and approximate locations of the control room intakes. The intervening structures between the release point and the control room intakes were ignored for calculational simplicity, thereby underestimating the true distance to the control room intakes.
Note that Section 3.4 of RG 1.194 states that, "If the distance to receptor is less than about 10 meters, the ARCON96 code and the procedures in Regulatory Position 4 should not be used to assess X/Q values. These situations will need to be addressed on a case-by-case basis.'
RG 1.194, however, does not provide alternative method for calculation of the X/Q values for these conditions. There is one release location at Waterford 3 (East atmospheric dump valve (ADV) to East Control Room (CR) intake, distance = 6.6 meters) that does not meet this guidance. The X/Q result for this location was compared with a location in a similar direction with a distance close to 10 meters. The comparisons indicated that the X/Q values for this location are reasonable for use in the dose calculation.
The reasonableness of the X/Q values for this location is also supported by the following:
The flow velocity out of the ADVs is ignored in the calculation of XIQs. This is very conservative, since the flow velocity adds to the release height.
ARCON96 allows for the calculation of the X/Q values for distances from 0 to 100 meters and does not specify any restrictions for the calculation of X/Q values for distances under 10 meters.
The following ARCON96 input data files, used to calculate various XIQs, are provided with filenames *.RSF (Run Specification Files) on the enclosed compact disc.

The XIQs were calculated for all possible release points (e.g., east and west side ADVs and main steam safety valves (MSSVs)) to both control room emergency air intakes.
The fuel handling accident (FHA) was previously analyzed using the current (old) X/Q values and EPU source terms. A conservative scaling approach has been applied to the previous FHA control room dose analysis to demonstrate that it remains acceptable for EPU. See PUR Section 2.13.7.3.4 for further discussion. The LOCA dose analysis used the new X/Q values, used the control room intake with the worst X/Q values (i.e., limiting release and intake pair), and did not credit any operator action to switch to the more favorable air intake.
Reduction factors were not used in the FHA or LOCA dose analysis.
Waterford 3 assumes 200 cfm filtered flow into the control room in the design basis accident (DBA) dose analyses. This flow rate is confirmed per TS surveillance requirement 4.7.6.5.
This surveillance requires that the control room pressurization test be performed every 18 months to demonstrate that the control room envelope can be maintained at a positive pressure of greater than or equal to 1/8 inch water gauge relative to the outside atmosphere with a make-up air flow rate less than or equal to 200 cfm. The flow is measured with safety related flow meters via control room indications.
While Waterford 3 is designed with two independent emergency air intakes, no reduction (e.g., as allowed for dual intakes) was credited in the FHA and LOCA analysis. The control room habitability systems are discussed in Waterford 3 Final Safety Analysis Report Sections 6.4, "Habitability Systems" and Section 9.4.1, uControl Room Air Conditioning System".

In order for the staff to evaluate the acceptability of the flow-accelerated corrosion (FAC) program, please provide a list of the components in the program most susceptible to FAC.
The list should include initial wall thickness (nominal), current wall thicknesses and future predicted wall thickness. Table 2.1-3 of the application shows the most significant increases in wear rate. Please clarify whether the piping listed in Table 2.1-3 are the most susceptible piping to FAC. If they are, provide initial and current wall thickness of these piping and predicted wall thickness of these piping in the current operating conditions and post-uprated conditions. If they are not, please provide the aforementioned wall thickness data of a sample of the most susceptible piping systems.
Response 1:
The Waterford 3 FAC Program Pre / Post Power Uprate Wear Rate Summary (see below) was populated using CHECWORKS (CW) model data and provides a list of those components with the highest wear rates (i.e., most susceptible to FAC.) The summary provides the nominal, current and future wall thickness for these components. These components are modeled in the CW program as run definition ES03 which encompasses lines ES-18, 19, 20, 21, and 22. These lines provide extraction steam (heating steam) from the high pressure turbine exhaust (crossunder (CU) piping) to the #2 intermediate pressure (IP) feedwater heaters. Lines ES-18, 19 and 20 make up the 34" header which has three -
20" lines feeding each of the three IP heaters. The header upstream of ES 18 was replaced with FAC resistant material in refueling (RF)-06. Crossunder and small bore piping cannot be modeled in CW. Inspection of CU and small bore piping are based on the following:
Results from previous refueling outage exams, Industry events, Operating Experience (OE),
engineering judgment, requests by plant personnel to examine specific components or systems, results from non-typical operation, and EPRI Plant Events database. The W3 FAC Program Pre / Post Power Uprate Wear Rate Summary was populated using CW model data.
PUR Table 2.1-3 does not list the most susceptible components in the program, it represents the lines with the most significant change in wear rates.
Question 2:
The pipe wall thinning caused by FAC is predicted by the Electric Power Research Institute's CHECWORKS computer code. In order to allow the staff to evaluate the accuracy of these predictions, please provide examples of the piping components for which wall thinning is predicted by the code based on the current operating conditions and at the same time measured by ultrasonic testing or any other method employed in Waterford 3. This procedure (predicted wall thickness vs. measured wall thickness comparison) will show the effectiveness of CHECWORKS in predicting the as-found condition.
to W3Fl -2004-0017 Page 2 of 1 1 Response 2:
The data in the Waterford 3 FAC Program Pre / Post Power Uprate Wear Rate Summary (see below) shows the predicted vs. measured data on the piping. Additionally, the CHECWORKS uComparison of Thickness Predictions" scatter plot (see below) gives a visual representation of the measured vs. predicted thickness for the CHECWORKS run ES03. The plot compares the predicted thickness (as adjusted by the line correction factor) with the measured thickness along the +/- 20% boundary lines and shows that CHECWORKS conservatively predicts the wear.

The last paragraph on page 2.1-11 states that during each outage, inspections are performed based on an aggressive program to identify piping in need of replacement.
(a) Please discuss the inspection technique and inspection scope (e.g., how many piping systems are inspected) in the Waterford 3 FAC program.
(b) As for the statement "...Repairs are performed to preclude falling below minimum wall thickness...," please discuss the specific subsection in the American Society of Mechanical Engineers (ASME) Code from which the minimum wall thickness is calculated.
Response 3:
Response (3a):
Inspection Technique Summary Ultrasonic testing (UT) is the primary means of gathering examination data. Waterford 3 uses the Panainetrics 36DL - Plus digital thickness meter to gather and store UT readings. All examinations are performed by non-destructive examination (NDE) technicians certified in accordance with the applicable Entergy Quality Assurance procedures. CHECWORKS modeled components are gridded to assure examination repeatability.
Small bore piping is scanned 100% to determine acceptability. Design engineering provides the minimum acceptable thickness required for all piping examined in the FAC program.
Crossunder (CU) piping and piping 2" and below are not gridded. Sections of CU piping are visually inspected, evaluated and repaired as required at every refueling outage.
The FAC program inspections are performed in accordance with the corporate and site procedures consistent with the recommendations found in the industry standard EPRI NSAC 202-L 'Recommendations for an Effective Flow Accelerated Corrosion Program".
Outage inspection scope is developed using the following information:
Inspection Scone Summary The following are monitored in the Waterford 3 FAC program:
- 1. feedwater,
- 2. blowdown,
- 3. feedwater heater drains,
- 4. extraction steam,
- 5. main steam drain headers,
- 6. condensate,
- 7. steam bypass, to W3Fl -2004-0017 Page 6 of 11
- 8. crossunder pipe, and
- 9. main steam.
The Waterford 3 FAC program scope is based on the "Waterford 3 System Susceptibility Evaluation" (SSE). The SSE was performed to determine the piping susceptible to the FAC mechanism under both pre-and post-power uprate conditions. The SSE was developed by reviewing the system descriptions, flow diagrams, and other plant documents to determine plant configuration and operation to determine the susceptibility category.
The SSE divides the piping into three groups:
Lines to be modeled using EPRI's computer code CHECWORKS FAC Lines that are susceptible, but not modeled (SNM) in CHECWORKS - small bore piping 2" and under usually socket welded.
Lines not sufficiently susceptible to require further analysis.
The following are also considered in determining the scope and priority of inspections.
Priority ranking based on CHECWORKS predictive analysis.
Results from previous refueling outage exams.
Industry events Operating Experience (OE)
Engineering judgment Requests by plant personnel to examine specific components or systems.
Results from Non-Typical Operation EPRI Plant Events database Response (3b):
The minimum wall thickness (tmin) of a component as defined in the ASME Code (NB/NC-3600) is based on hoop pressure stress only, since bending moments and other loads are assumed not to produce a stress component in the hoop direction. The ASME Code puts additional restrictions on combined axial stress due to primary and secondary membrane and bending loads, and these restrictions may affect tmin.. That is, tmin may be required to be increased until these equations are satisfied.
The tmin equations refer to a global minimum thickness throughout the entire cross section of the pipe or component. For wall thinning in piping due to FAC that occurs in a localized region, the decision to replace the piping is based on comparing measured or projected wall thickness at the localized region with the allowable localized wall thickness (taioc). taloc is the minimum thickness, based on the geometry of the thinned location, calculated from ASME Code proximity criteria, equations and allowables for Class 1 piping (NB-3200, Alternate Design Rule by analysis). Although the rules of NB-3200 are only strictly applicable to ASME Section III, Class 1 piping, it is felt that application of the rule to piping systems designed to other Code is technically justified, as long as the component stresses and constituent equations and the allowable stress values are used appropriately and equal to those contained in the original code of construction.
to W3Fl -2004-0017 Page 7 of 11 Since ASME Code does not address degraded piping, EPRI developed acceptance criteria using Classl Code design rules that dictate screening criteria for identifying wall thinning which is acceptable without further evaluation and thinning for which immediate repair or replacement is required.
Based on the above guidance, Entergy has developed acceptance criteria for degraded piping to evaluate when repair or replacement is required.
Question 4:
The first paragraph on page 2.1-12 states that "...if the measured wall thickness at the current refueling outage, and/or, the projected wall thickness at the next refueling outage falls below the code allowable wall thickness, the piping should be replaced..."
(a) Since the ASME code does allow pipe wall thickness to fall below the nominal wall thickness but not the minimum wall thickness, please clarify the terminology "code allowable wall thickness" on page 2.1-12.
(b)
Discuss the limit on the percentage of wall thickness below which the pipe is replaced.
(c)
Discuss whether the pipe replacement due to FAC is consistent with (1) ASME Code, Section Xl, Case N-597-1, which is referenced in RG 1.147. Revision 13, "Inservice Inspection Code Case Acceptability-ASME Section Xl, Division 1," June 2003; and (2)
EPRI Report, "Recommendations for an Effective Flow-Accelerated Corrosion Program,' NSAC-202L-R2, April 1999.
Response 4:
Response (4a)
See response to 3b above.
Response (4b)
Decision of piping replacement is based on comparing the calculated projected wall thickness with the acceptable minimum wall thickness of the pipe.
The calculation of projected wall thickness (tp) is based upon an established rate of wear to some point in time (e.g. next refueling, next scheduled examination). The calculation of projected wall thickness use a safety factor as recommended in EPRI NSAC-202L.
Waterford 3 has used a safety factor of 1.1 (additional 10% over calculated projected wall thickness).
Entergy replacement criteria meets the intent of the EPRI Guideline Document (NP-591 1SP) that recommends to replace the piping component when measured or projected wall thickness falls below 20% of nominal wall thickness. At Waterford 3 the replacement or repair of piping components is performed when:
- The projected wall thickness is below 30% of nominal wall thickness (ASME Class 1 and 2 Piping).
to W3Fl -2004-0017 Page 8 of 11 The projected wall thickness is below 20% of nominal wall thickness (ASME Class 3 Piping).
The projected wall thickness is lesser of 0.3tnomina, and 0.5tmnimum for Class 3 Low Energy and B31.1 Piping (Non-safety).
Response (4c):
The existing piping replacement criteria at Waterford 3 are consistent with the EPRI Guideline and/or NRC requirements as specified in EPRI-NSAC-202L, Revision 2 document.
ASME Section Xl (Division 1), Code Case N-597-1, provides the requirements for analytical evaluation of pipe wall thinning. This code case must be supplemented by the provisions of EPRI nuclear safety analysis center report 202L-R2, April 1999 for developing the inspection requirements, the method of predicting the rate of wall thickness loss, and the value of predicted remaining wall thickness. Further, components affected by flow-accelerated corrosion to which this code case is applied must be repaired or replaced in accordance with the construction code of record and owner's requirements or a later NRC approved edition of Section III of the ASME Code prior to the value of tp (projected wall thickness) reaching the allowable minimum wall thickness, tmn, as specified in the above code case ((3622.1(a) (1)).
At Waterford 3, for the flow-accelerated corrosion program, the inspection requirements, and the method of predicting the rate of wall thickness loss (wear rate), and the value of predicted remaining wall thickness meet the intent of NSAC-202L, Revision 2.
The measured/projected wall thickness as obtained during the outage is evaluated and compared to the calculated acceptable minimum wall thickness as discussed previously.
If the projected wall thickness is below the acceptable minimum wall thickness, then a detailed engineering evaluation is performed following the Entergy standard. This standard provides a unified methodology for evaluating localized thinning in piping for ASME Section 1II, ANSI B31.7, and ANSI B31.1 carbon steel piping.
The decision to repairing or replacing a component is based on detailed evaluation results:
Replacement of the pipe in the area of local thinning.
Local repair of pipe wall.
Use of load bearing overlays.
Use of non-Code but qualified repair technique based on ASME Relief Request.
Increased re-inspections of local pipe wall area.
Inspection of other susceptible locations.
Per review of the ASME Code Case N-597-1 and NRC requirement document NSAC-202L, Rev 2, the acceptance criteria and replacement/repair criteria used at Waterford 3 meet the intent of the above code case and NRC criteria document.
to W3Fl -2004-0017 Page 9 of 11 Question 5:
Section 2.1.9 states that Waterford 3 has implemented the requirement of Nuclear Energy Institute (NEI) 97-06 SG Program Guidelines. It is recommended in NEI 97-06, Revision 1, January 2001, that primary-to-secondary operational leakage be limited to 150 gallons per day per SG. However, in the proposed changes to TS 3/4.5.2c it is proposed to change the primary-to-secondary operational leakage from 720 gallons per day per SG to 540 gallons per day per SG. Discuss why NEI 97-06 recommended operational leakage limit of 150 gallons per day per SG is not being adopted even though NEI 97-06 is implemented at Waterford 3.
Response 5:
The TS change provided to reduce the primary-to-secondary operational leakage limit in TS 3/4.5.2c from 720 gallons per day to 540 gallons per day will be revised to reduce the primary-to-secondary operational leakage to 150 gallons per day in agreement with NEI 97-
- 06. The 1 gpm total primary-to-secondary operational leakage limit will also be revised accordingly. Due to the required administrative reviews for a TS change, this change will be provided in a future supplement to the EPU submittal to be submitted by the middle of July 2004.
Question 6:
The licensee states that feedwater flow will be increased as a result of extended power uprate, and the capacity of the SG blowdown system under power uprated conditions will still be adequate to maintain chemistry in the secondary systems.
(a) Please discuss the feedwater flow increase in the power uprated conditions as a percentage of the original rated flow.
(b) If the blowdown flow is increased as a result of increased feedwater flow rate, provide a percentage of the increase in terms of original rated flow.
(c)
Discuss whether the blowdown demineralizers are adequate to treat the increased blowdown flow rate under the power uprated conditions.
Response 6:
Response (6a):
The original rated feedwater flow is 15855370 Ibm/hour at maximum "not guaranteed" conditions. The calculated EPU feedwater flowrate at the same conditions is 17030736 Ibm/hour. The power uprate calculated flow rate results in a 7.4% increase from the original rated flow.
However, with respect to the blowdown flow, the increase in feedwater flow is independent from the blowdown flow.
to W3Fl -2004-0017 Page 10 of 11 Response (6b):
The steam generator blowdown system is designed to provide a flow to each blowdown demineralizer bed between 60 to 425 gpm. This design flow range is not changing as a result of the increased feedwater flow. Chemistry personnel will continue to operate the steam generator blowdown system within this flow range which has been determined to be an acceptable flow range to maintain water chemistry parameters for the power uprate. Blowdown flow rate is regulated in accordance with Chemistry Department instructions.
Response (6c):
As discussed previously, rated blowdown flowrates are not increased for power uprate conditions. The blowdown demineralizers beds are designed to accept a maximum flow rate of 700 gpm each which is greater than the maximum normal design flow of 425 gpm.
Therefore the maximum demineralizer bed capacity exceeds the normal blowdown flowrates necessary to maintain proper secondary water chemistry.
Question 7:
Please clarify whether the primary and secondary water chemistry programs follow the primary and secondary water chemistry guidelines in EPRI reports TR.105714 and TR-102134, respectively.
(a) Clarify which revision of the EPRI reports are currently being used at Waterford 3.
(b) Clarify whether procedures are implemented at Waterford 3 to adopt the latest version of the EPRI water chemistry reports, if they are revised in the future.
Response 7:
Response (7a):
- 1. Primary Chemistry program is currently based on, EPRI PWR Primary Water Chemistry Guidelines, Revision 4, EPRI TR-105714-VlR4 and EPRI TR-105714-V2R4, March 1999. (Note: EPRI issued Revision 5 to the PWR Primary Water Chemistry Guidelines in September 2003, EPRI 1002884 Volumes 1 and 2, which is currently scheduled for implementation at Waterford 3 by June 2004.)
- 2. Secondary Chemistry program is currently based on, EPRI PWR Secondary Water Chemistry Guidelines, Revision 5, EPRI TR-102134, May 2000 and EPRI Interim PWR Secondary Water Chemistry Recommendations for IGA/SCC Control, EPRI TR-1 01230, September 1992.
- 3. Primary to Secondary Leakage program is currently based on EPRI PWR, Primary-to-Secondary Leak Guidelines, Revision 2, EPRI TR-104788, April 2000.
to W3Fl -2004-0017 Page 11 of 11 Response (7b):
There is currently no specific procedure which directs the implementation of revisions to these guidelines. The current process is to use the paperless condition report system (PCRS) to generate a Waterford learning organization (WLO) Condition Report documenting the revised guideline with corrective actions generated to the specific site departments (e.g., Operations, Radiation Protection, Design Engineering, System Engineering, and Chemistry) to review the revised guideline for impact to their respective programs. The review is currently documented as a Snapshot Assessment and any programmatic changes necessary will be identified as an Area for Improvement (AFI),
with specific scheduled implementation dates.
