-04'00' CNL 25-019 Response to NRC Request for Additional Information CNL-25-019 E1-1 of 6 NRC Background Pursuant to 10 CFR 50.90 and by letter dated August 28, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24247A180), the Tennessee Valley Authority (TVA or the Licensee) submitted a license amendment request (LAR) for Renewed Facility Operating License Nos. DPR-77 and DPR-79 (i.e., Units 1 and 2 of the Sequoyah Nuclear Plant (SQN), respectively). The purposes of the LAR are to revise the fuel handling accident (FHA) analysis, to delete Technical Specification (TS) 3.9.4, and to modify TS 3.3.6.

Data and information needs pertaining to the accident-related atmospheric dispersion modeling and the meteorological (Met) data input to that modeling were originally identified during the pre-application meetings of March 18 and July 16, 2024 (see ML24082A253 and ML24218A218, respectively). The NRC staff reviewed the initial LAR submittal. Gaps in the identified data and information needs were brought to the Licensees attention in mid-to late-September 2024. TVA responded later that month by providing or clarifying the necessary data and information on DVD.

On October 2, 2024, the NRC staff notified the Licensee by email (see ML24281A007) that technical information had now been provided in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. That email also stated that there may be instances in which issues that impact the NRC staff's ability to complete the detailed technical review are identified, despite completion of an adequate acceptance review and that TVA would be advised of any further information needed to support the NRC staff's detailed technical review by separate correspondence.

The following requests for additional information (RAIs) have been identified during the NRC staffs detailed technical review. These RAIs pertain only to the review of the accident-related onsite and offsite atmospheric dispersion modeling, the results of which are direct inputs to the FHA radiological dose analyses, and to the Met data supporting those dispersion analyses.

Regulatory Basis The accident-related radiological dose analyses that accompany this LAR require atmospheric dispersion parameters (i.e., relative concentrations or X/Qs) as direct inputs to the dose calculations. These X/Qs are based on using appropriate dispersion models that rely, in part, on the input of representative Met data. The dispersion analyses for this LAR consider both onsite and offsite impacts. Onsite X/Qs are estimated at the normal and emergency air intake locations to evaluate potential impacts to control room habitability.

The normal and emergency air intakes serve a control room that is common to Units 1 and 2. Offsite X/Qs are estimated at the Exclusion Area Boundary (EAB) and the outer boundary of the Low Population Zone (LPZ) to evaluate potential impacts to the public.

Request for Additional Information

RAI-1

The NRC Staff reviewed documentation provided on DVD with the original LAR submittal (see ML24247A180) as related to the offsite atmospheric dispersion analysis with the PAVAN model. This analysis supports the revised fuel handling accident (FHA) dose assessment of potential impacts to the public. The information reviewed included:

x titled Description and Assessment of Proposed Changes (see ML24247A175);

x titled Calculation of Atmospheric Dispersion Factors Exclusion Area Boundary & Low Population Zone for SQN Units 1 & 2 (see ML24247A171);

x titled Joint Frequency Distributions of Wind Speed and Direction 2004 to 2013 SQN Units 1 & 2 (see ML24247A173); and x titled ARCON96 Files, Hourly Meteorological Data for 2002-2013, MET Data Files, and PAVAN Files.

A more usable form of hourly Met data for the 2004 to 2013 period of record (POR) was provided on DVD in late September 2024.

of the DVD included three pairs of PAVAN model input and output files - that is, x

pavan.2004-13.e1.ws.h.INP and sqn.pavan.2004-13.e1.ws.h.OUT; x

pavan.2004-13.e2.ws.h.INP and sqn.pavan.2004-13.e2.ws.h.OUT; x

pavan.2004-13.e3.ws.h.INP and sqn.pavan.2004-13.e3.ws.h.OUT.

CNL-25-019 E1-3 of 6 The designators e1, e2, and e3 correspond to EAB receptor distances of 556, 600, and 509 meters, respectively, for three release zones evaluated to determine the most conservative release point for the EAB as described in Enclosure 1 under the heading Offsite X/Qs. The distances to the outer boundary of the LPZ were the same (i.e., 4828 meters) in all three pairs of the PAVAN input / output files.

The output files indicate that the three model runs were made on October 2, 2019. Further, is designated as Revision 1 and the Prepared By and Reviewed By signatures are likewise dated October 2, 2019.

Based on the input specifications for the PAVAN model listed in NUREG/CR-2858, the NRC Staff identified an error common to all three input files in the latter portion of Card Type 10.

The entries in Columns 6 through 75 correspond to the maximum wind speeds (i.e., UMAX) for each wind speed category in the joint frequency distributions (JFD) of wind speed and wind direction by stability class also input to the model. The error begins with the 8th UMAX value (i.e., the entry should be in Columns 41-45) and continues through the entry for the12th UMAX value. These entries are offset by progressively one more space such that the 12th entry is fully offset by five columns. The last numeral of the last two UMAX entries appear at Columns 75 and 80, respectively, but because of the progressive offset they should end at Columns 70 and 75. If corrected as is, there would be no entry in Columns 76 to 80 based on the JFD.

The error did not prevent the model from executing the X/Q calculations. Rather, various portions of the model output were obviously affected (e.g., echoes of certain wind speeds in the JFD). These effects can be seen in each of the three corresponding output files. What is not readily evident from this error is whether certain X/Q calculations were affected such that the ordered X/Q distributions might have been altered. Therefore, address the following:

Confirm the apparent error and whether or not any of the X/Q values used as direct input to the dose calculations in this LAR are affected. If so, provide an assessment of the impact of this error and describe the planned corrective actions.

TVA Response TVA confirms the formatting error in the PAVAN input files. This issue has been documented in the TVA corrective action program. The corrective actions include resolving the formatting error in the PAVAN files and determining the corrected /Q values, revising the FHA analysis with the corrected /Q values as necessary, and revising other calculations that used the /Q values as necessary.

The new /Q analysis determined the values used as direct input in the FHA analysis were not impacted. Thus, the FHA analysis provided in the original submittal remains valid.

CNL-25-019 E1-4 of 6 The new /Q analysis is provided as Enclosure 2 of this submittal.

x of this submittal replaces what was provided in Enclosure 3 of the original LAR dated August 28, 2024.

x to Enclosure 2 of this submittal contains the same Joint Frequency Distributions of Wind Speed and Direction (JFDs) that were provided in Enclosure 5 of the original LAR.

x Attachments 3 and 4 to Enclosure 2 of this submittal replace the PAVAN output files provided in Enclosure 6 of the original LAR.

x The original PAVAN input files in Enclosure 6 of the original LAR are superseded by the new /Q analysis provided in Enclosure 2 of this submittal. Because the output files are a direct function of the input files, the input files will not be resubmitted.

However, note that Attachments 3 and 4 to Enclosure 2 of this submittal each begin with input file data.

In addition to correction of the formatting error in the PAVAN input files (noted by NRC in RAI-1), there are two minor differences between the PAVAN models used for Enclosure 2 of this submittal as compared to the models used for Enclosure 3 of the original LAR.

1. There are only two models in this submittal versus three in the original. The original three models corresponded to each of the three EAB distance and each model also contained the same LPZ distance. The new analysis determines the /Qs for two of the EAB distances in one model, and then the second model contains the third EAB distance and the LPZ.

2. The new models contain twelve wind speed categories versus thirteen in the original model. The 13th category was input as 0 and had no JFD input data (i.e., all 0's).

Therefore, it was removed from the model.

RAI-2

The NRC Staff reviewed documentation provided on DVD with the original LAR submittal (see ML24247A180) related to the onsite atmospheric dispersion analysis with the ARCON96 model. This analysis supports the revised FHA dose assessment for control room habitability. The data and information reviewed included:

x (see RAI No. 1 for the title);

x titled Calculation of Atmospheric Dispersion Factors - Control Room (see ML24247A174);

x titled Marked-up Equipment Layout Drawings; and x (see RAI No. 1 for the title).

As with RAI No. 1, a more usable form of hourly Met data was provided for the 2004 to 2013 POR on DVD in late September 2024.

of the DVD included about a dozen pairs of ARCON96 model input and output files. As a set they represent potential accident releases from the auxiliary building vent, the Unit 1 shield building, and the Unit 2 shield building. Their purpose, which assumed different building dimensions that could affect the degree of dispersion, was to estimate X/Q values at the normal air intake and the emergency air intake to the plants common control room and to identify the contributing release point(s). The resulting maximum X/Qs were then determined for possible use as input to updating the FHA dose assessment. These iterative model runs were made in early August 2019.

CNL-25-019 E1-5 of 6 The DVD also included two ARCON96 output files (i.e., TVA_083 and TVA_187). These two model runs were made previously in November 2014. From among the 2019 iterative set of model runs and the 2014 pair of model runs indicated above, the overall highest X/Qs at the normal and emergency air intakes are associated with the TVA_083 and TVA_187 model runs. These values were due to potential releases from the auxiliary building vent and are listed in Enclosure 2 in several places (e.g., see Table 5-1). Of these two values, the controlling (overall highest) X/Q was associated with the TVA_187 model run (i.e., at the normal air intake). Enclosure 1 includes a broader summary of the 2019 and 2014 accident-related modeling results (e.g., see Table 3.1.1-3) listing the highest X/Qs by source and receptor.

All ARCON96 output files echo the respective inputs for a given modeling run. Both the iterative set of model runs from 2019 and the two model runs from 2014 used the same Met data from the 2004 to 2013 POR. The designators 083 and 187 in the filenames for the TVA model runs correspond to the straight-line wind direction from the emergency air intake and the normal air intake, respectively, towards the auxiliary building vent as shown in Figure 3-3 of Enclosure 2.

However, the NRC Staffs review of the TVA_083 and TVA_187 output files identified several discrepancies with portions of the documentation in Enclosure 2, dated in December 2014, that are inconsistent with certain ARCON96 model input parameters and/or within the documentation itself, and/or the ARCON96 modeling guidance in NUREG/CR-6331. These include but may not be limited to:

x Record of Revisions (Page 9 of 57 of Enclosure 2 or Page 6 of 54 of FAI/14-0989, Rev. 2). The purpose of Rev. 2 is stated to be to create a non-proprietary version of this calc note. The Rev. 1 description indicates that the the building area used in analysis is 17565.167 ft2. That value only corresponds to the rectangular area projected by the cylindrical containment building as stated in Section 3.4. This is inconsistent with the building area value discussed in Section 3.4 which includes the circular segment (Figure 3-2) projected from the upper containment dome and in the input echoed in the TVA_083 and TVA_187 output files. Note that a smaller building area may result in higher X/Q values and, therefore, doses.

x Section 3.2, Table 3-3 entry for Building area (m2) for building wake effects is listed as 1744.1 sq-m but is inconsistent with the value of 1744.7 sq-m for the total projected building area in Section 3.4, the entries in Tables 3-5 and 3-6, and the input echoed in the TVA_083 and TVA_187 output files.

x Section 3.2 (Para. 1, Sent. 3) states For this analysis, only the distance to the receptor and the direction to the receptor are changed between the cases. The phrase the direction to the receptor is incorrect in that ARCON96 model users guide (i.e., in NUREG/CR-6331) calls for the opposite sense to be provided (i.e., the direction from the receptor to the source). The correct orientation in the model input was verified but the indicated text needs to be revised.

x Section 3.1 (Para. 3, Sent. 2) incorrectly references Table 3-1 for Other meteorological inputs required by ARCON96 (i.e., years of Met data, lower and upper measurement levels, and wind speed units of measure). The correct cross-reference is Table 3-2.

CNL-25-019 E1-6 of 6 x

Section 3.5, Table 3-5 is titled Table 3-5 Input for Case TVA_175 (Normal Intake Location) and should either be corrected to read Table 3-5 Input for Case TVA_187 (Normal Intake Location), or revise the TVA_187 modeling run including any affected dose calculations.

x Section 3.5, Table 3-6 is titled Table 3-6 Input for Case TVA_084 (Emergency Intake Location) and should either be corrected to read Table 3-6 Input for Case TVA_083 (Emergency Intake Location), or revise the TVA_083 modeling run including any affected dose calculations.

Individually, some or all of the items above may just be inconsistencies in the indicated documentation for this part of the current LAR although much of Enclosure 2 and the controlling model runs are 10 years old. Further, this may not be a complete list of the disconnects. However, in aggregate, if there are discrepancies between the documentation and certain inputs to the ARCON96 dispersion modeling, then the resulting X/Qs and downstream dose calculations may be affected.

Therefore, provide an assessment of these potential inconsistencies or discrepancies with respect to the revised FHA dose assessment for control room habitability.

TVA Response This issue has been documented in the TVA corrective action program. TVA has reviewed the noted items and determined they are all editorial in nature. Therefore, there is no impact to the revised FHA dose assessment submitted as part of the LAR.

Short-Term (Accident) Dispersion Estimates - PAVAN 1.0 Purpose This calculation documents the evaluation of the short-term atmospheric dispersion coefficients, expressed as X/Q values, for use in the offsite accident radiological consequence analyses at the Sequoyah Nuclear Plant (SQN) as required under 10 CFR 100.10 (Reference 10.1) and 10 CFR 50.34 (Reference 10.2) and as presented in RG 1.145 (Reference 10.4). The calculations are performed using the PAVAN computer program, NUREG/CR-2858 (Reference 10.3), which was developed and is used by the U.S. Nuclear Regulatory Commission (NRC) for this type application. The PAVAN program implements the guidance provided in NRC Regulatory Guide (RG) 1.145, "Atmospheric Dispersion Models for Potential Accident Consequence Assessments at Nuclear Power Plants (Reference 10.4). The PAVAN model calculates X/Q values based on the theory that material released to the atmosphere would be normally distributed (Gaussian) about the plume centerline.

2.0 Design Input Data 2.1 As an input in PAVAN, Joint Frequency Distribution (JFD) data is taken from Reference 10.6 and converted to an hourly representation for input into PAVAN by multiplying all values by the total amount of hours of valid data (86420 hours) to be consistent with previous SQN PAVAN format. Reference 10.6 JFDs were generated with a site specific program using meteorological data from 2004 through 2013 for a total of 10 years of data. Per Reference 10.6, the met tower data met the requirements of Reference 10.7 and was validated in accordance with Reference 10.5. The data has a greater than 90% recovery rate as required by RG 1.23 (Reference 10.7). A conversion variable (UCOR=150) was used in PAVAN to flag conversion of the wind speeds to meters/second from miles/hour. The Joint Frequency Distributions are presented in Appendix 1. The upper bound wind speeds category limits provided by Reference 10.6 in miles per hour are as follows: <1.12, <1.68, <2.24, <2.80, <3.36, <4.47,

<6.71, <8.95, <11.18, <13.42, <17.90, and <22.37.

2.2 The effluent release zones for the Sequoyah Plant were defined for three locations: (1) Release Zone 1, the Auxiliary Building vent exhaust and the Shield Building vent exhaust; (2) Release Zone 2, the radioactive chemical hood exhaust; and (3) Release Zone 3, the condenser air ejector exhaust (Reference 10.8, Section 2.3.4.2). The distances between the release point and the EAB Boundary for Release Zones 1 through 3 are taken from Section 2.3.4.2 and Table 2.3.4-1 of Reference 10.8 and are shown in Table 1 below. The 16 distances between the postulated release point and the EAB or LPZ Boundary are normally entered into PAVAN by sector, beginning with the distance to the south boundary, then to the SSW, SW, and onward ending with SSE. All distances for this evaluation are the same for all directions.

Short-Term (Accident) Dispersion Estimates - PAVAN Table 1: Shortest Boundary Distances Release Zone Shortest Boundary Distance (meters)

Release Zone 1 556 Release Zone 2 600 Release Zone 3 509 LPZ 4828 2.3 The Meteorological Tower instrumentation measures wind speed at the 9.73 m elevation above grade and temperature at 9.25 m and 45.99 m. (Reference 10.9) 2.4 One of the two Primary Containment buildings is credited for building wake effects per RG 1.145 (Reference 10.4), with the minimum cross-sectional area of the cylindrical structure being the height multiplied by the diameter. From Reference 10.10, the height is 134 ft and radius is 65 ft and 6

in.

Converting to meters and multiplying twice the radius by the height results in an area of 1632 m2. Note that the height of the containment building above grade (134 ft, or 40.8 m) is an input in PAVAN as well.

3.0 Assumptions 3.1 The release is assumed to be a ground level release. This is consistent with the requirements of RG 1.145 (Reference 10.4) for containment releases, which requires the release point to be 2 and 1/2 times higher than the containment building in order to credit an elevated release. Per Reference 10.3, a ground level release is input into PAVAN as a 10 meter release height.

3.2 Consistent with the assumptions outlined in the SQN Final Safety Analysis Report (FSAR) Section 2.3.2 (Reference 10.8), the onsite meteorological data is representative of the actual transport and diffusion characteristics of the site vicinity; therefore, no terrain adjustment factors were applied.

3.3 All distances for this evaluation are assumed to be the same for all directions. This is conservative as the minimum distance for each Release Zone was selected, and shorter distances will result in higher X/Q values.

Short-Term (Accident) Dispersion Estimates - PAVAN 6.0 Computations and analysis Using joint frequency distributions of wind direction and wind speed by atmospheric stability, the program provides relative air concentration (X/Q) values as functions of direction for various time periods at the exclusion area boundary (EAB) and the outer boundary of the low population zone (LPZ). Calculations of X/Q values can be made for assumed ground-level releases (e.g., through building penetrations and vents) or elevated releases from free standing stacks. (Reference 10.3)

All computations were performed using PAVAN for this evaluation, using the inputs and assumptions of Sections 2 and 3 above. The input files are saved in CMIS for this calculation. The output files are saved as Attachments 3 and 4 in CMIS for this calculation.

The PAVAN manual (Reference 10.3) states that the X/Q value for the EAB or LPZ boundary evaluations will be the maximum sector X/Q or the 5% overall site X/Q, whichever is greater. This instruction is consistent with Regulatory Guide 1.145 (Reference 10.4).

In the result files, Attachments 3 and 4 of this calculation uploaded in CMIS, the first section is a repeat of the input file that is provided. In the event that the input file has values larger than PAVAN can display in this repeat, PAVAN will return a series of stars (*******) instead of a numerical value. This has no impact on the results of the calculation, but the values replaced by stars may only be viewed in the input file.

7.0 Supporting Graphics None.

8.0 Summary of Results RG 1.145 (Reference 10.4) requires that the /Q values at the EAB and LPZ be calculated based on both a directionally dependent methodology (maximum sector) and a directionally independent methodology (overall site limit) and that the most conservative (highest) values be used in subsequent analyses.

Table 2 shows the Exclusion Area Boundary (EAB) /Q values for Release Zones 1 through 3 for the first two hours following an accident. The values shown, unless otherwise specified, are the 0.5% maximum X/Q values for the time period of 0-2 hours.

As a check of the calculated directionally dependent Site Limit X/Q values, a logarithmic interpolation of the results using the 0-2-Hour Site Limit (6.25 E-05 sec/m3) and the limiting sector annual average (1.45E-06 sec/m3) X/Q values is necessary per the guidance of Reference 10.3, Section 4.6. The interpolated slope and intercept were determined using Equations 1 and 2 respectively:

ln ln ln2 ln 8760 1 ln ln2 2 Where, is calculated in PAVAN as 6.25E-5 s/m3 for the 5% Site Limit and is calculated in PAVAN as 1.45E-6 s/m3 for the limiting sector (SSW). is calculated to be -4.49E-01, and is -9.37.

The X/Q values for each period of time,, are calculated using Equation 3:
