- 1. Objective Theq purpose of this calculation isto determineconservativeestimates ofexclusion area, boundary (EAB) and low population zone .(LPZ) atmospheric dispersion coefficients (XIQs)for use inacalculations which determine'radiation dose consequences associated with; postulated design basis accidents occurring :at Nine Mile Point Nuclear ;Station ,(NMP) Unit '1and Unit,2.
2.Baickg roun d NMP has requested the services of Constellation Nuclear SerVices .(CNS)to evaluate and Update offsite and Control room atmospheric dispersion coefficients'for both Units 1 and 2.
The atmospheric dispersion coefficients are needed for a scoping study to determine the feasibility of the Use'of the Alternative Source Term (AST) methodology for the determination oftdesign basis accident dose consequences and can be applied'to other calculations which
,determine radiation dose bonsequences, at the EAB ':and LPZ boundaries.
Afterawpostulated accident at the NMP Unit 1 or Unit 2, radioactivity may reach the
,atmosphere by Several pathways. These pathways include the reactor building blowout panelo the turbine bUilding blowout panel and the mainrstack for Unit 1.For Unit 2, the release,
.pathways iniclude-the combined radwaste. andireactor building vent,,the main steam tunnel,.the standby gas treatment 'system building, the post accident sampling system panel and the main stack. Once the'radioactivity reaches the.atmosphere, it will: create dose consequences atthe EAB and the outer boundary of the LPZ. The determination of atmosphenc dispersion coefficients provide the amount of radioactivity reaching the EAB and LPZ for a given source for use in the dose consequence determination.
This calculation provides conservative estimates of atmospheric dispersion coefficients at the
,EAB and .LPZ 'from the following release sources:
- Unit I Main Stack
- UnitI Reactor Building Blowout Panel
- Unit 1 TurbineBuilding BlowoLut Panel
- Unit 2 Main Stack
- Unit 2 Combined Radwaste and Reactor Building Vent
- Unit 2 Main Steam Tunnel
- Unit 2 Standby Gas Treatment System Building
- Unit`2 Post.Accident Sampling System Panel 2.11. Applicable Regulations and Commitments PAVAN is used to determine X/Q values used in the assessment of dose consequences of
,design basisaccidents in nuclear power stations. 10 1CFR Part 100 (Reference 6) and 10CER Part50 '(Reference 7) require such assessments. PAVAN follows the guidance of R.G. 1.145 (Reference 2) for calculating X/Qs. Meteorological data~arebhourly averages obtained from Page 3 of 45
"Calculation No: NMPAST-01o001 Nulearteruices. Rev. 2 Nucle(arSer.vices Date: Dec. 19, 2003 NMP Joint Frequency Distribution Report.(JFD) (Referenceg) and: the analysis conforms to R.G. 1.145 (Reference 2 )-and R.G. 1.23 (Reference 21).

- 3. Methodology The PAVAN program uses meteorological data in the form of joint'frequency distributions of hourly averages of wind direction and wind speed by atmosphenrc stability class. Wind direction is distributed into 1:6 sectors. For each sectora 0.5% X/Q is calcUlated :to represent theO -2 'hourX/Q 'in accordance with R.G. 1.145 (Reference2). The 0.5% X/Q "is the value which is equaled or exceeded 0.5%,of the'time. PAVAN also :calculates .a sector annual average X/Q. in accordance with R.G. 1 111 ( 3 TheD 0-2 hourX/Q value and the annual average X/Q are used to determine:.sector X/Q values.for-various intermediate time,.
periods.
In a similar manner, PAVAN also calculates~a 5% overall site X/Q value that is independent of wind.direction. :This is:the site value that is not exceeded more-than 5% of the time, and is iusedto represent the o -.2'hour X/Q. The overall site annual average X/Q is calculated in accordance with R.G. 1.111 (Reference 3). The 0-2"hour X/Q Value and theannual average X/Q9are used to deotermine overall site X/Q values for various intermediate time periods.
In addition, PAVAN also calculates short-term sector fumigation X/Qs for both the EAB and LPZ in accordance with R.G. 1.145 (Reference 2),for stack releases. For each sector, :the.
larger of the sector fumigation and the sector non-fumigation X/Q should be used for theO - 2;
'hur.timeperiod., The highest X/Qvaluefor the 1.6 sectors represents the maximum sector X/Q.
'The X/Q-value forEAB or LPZ evaiuations should be themaximum sectorX/Q or the 5%
overall site X/Q, whichever is.higher. A more detailed description on the methodology used;by PAVAN tocalculate XIQs is provided in the reference documentation (References 2,:3 and .8).

- 4. Computer HardwarelSoftware Usage 4.1,.,Hardware Used All PAVAN X/Q calculations were performed on PC CNS-76, operating under the Windows 98 operating system. PAVAN has been previously verified on CNS-76min accordance with the CNS QA Program (Reference 15).
4,2. Software Used The program PAVAN is written in FORTRAN IV computerlanguage and is compatiblewith a CDC 7600 computer system under the NOS 1.0 Operating system. A further description of PAVAN is included -in the user's guide .(Reference 8).
Microsoft Excelwasalso used for calculatiron.purposes outlined in Sections 5.2.3, 6.1 ý,and 6.2. In accordance with the. CNS QA Program (Reference 1), no computer code verification is required for Excel.
- 5. Inputs andAAssumptions 5.1. Design Input Table 5 1-1 summarizes the design input used to generate the input filesfor the PAVAN calculations. The actual input files for PAVAN are included in the Input'Files folder on the enclosed CD,. Specific inputs for the meteorological data (Card 9):of the PAVAN input file are
'indicated in Table 5.1-2. The meteorological data was obtained from the-NMP Joint Frequency Distribution Report (JFD),(Reference 9) and appears in the Revised NMP 60m JFD 1997-2001 for CNSfile on the enclosed CD. Complete descriptions and proper formats of each data
,.input is included in the PAVAN usees guide (Reference 8). No tables are provided.for'the
..following calculations:
- Unit 1 Turbine Building Blowout Panel A Unit 2 Main:,Steam Tunnel
. Unit,2 Standby Gas Treatment System Building:
o Unit.2 Sampling System. Panel The reason for.the omission of these tables. is explained inSection 5.2.4.1 The design inputs required for calculating the, off-site X/Qs u.using PAVAN were obtained from
,the following documents:

SNMP Unit 2USAR Figure 1.2-11 (Reference 17) 5.2. Assumptions 5.2.1. Release PointDistances tothe EAB and LPZ Due to the close proximity of the Unit I reactor building blowout panel with the turbine building blowout panel, identical distances to the EAB and LPZ were used for each ofthese release points.
Due to the close proximities of the Unitl2 combined radwaste and reactor building vent, the
.main stearm tunnel,, the stand by. gas treatment system building and the post accident sampling system panel, identical distances to the EAB and LPZ were used for eacdhof these release
- points.
5.2.2. Building Wake Correction Factors For the cases involving groundlevel releases,, the-smallest vertical-plane cross-sectional area of the corresponding reactor building, i*n 2 , was used in accordance with:R.G. 1.145
'(Reference 2). An area of 2,082 m2 was used (References 1:0, 1,9 and 20) for,the Unit 1 releases classified as ground level, and an area of 2844 m 2 was:used:(Reference 14)-for the
.Unit 2 releases classified as ground level.
5.2.3. Site Topography For both Units' main stack releases, distances of 3,000 m and 6,000 m were selected for input as distanceswith terrain data for each sector. Two distances were selected to provide sufficient description of how terrain, height varies around the entire site. 6,000 m Was.selected since it representsroughly the entire distancefrom the stack releases tothe LPZ. 3,000 m was'selected since-it represents roughly half of the:distance::from the stack releases to the
.LPZ. Terrain heights for all 16 sectors were provided in Reference 13 at various distances
'foro the site. A straight-line slope was assumed to exist between the terrain height at the Site and :the terrain heightat various distances fromrthe site. The straight line slopes were used in Microsoft.Excel to estimate the.terrain heights at 3,000o m and '6,000 m. For any terrain height calculated as less than plant gradeelevation, a terrain height of zero meters was assumed, since-the height above plant grade level is called forin the PAVAN user s guide Page 6 of 45
Calculation No: NMPAST-01-001
'~PON3E~LJhPU. ev. 2 Nuclear Services Date:` Dec. 19,2003 (Reference 8). This entire. terrain heightcalculation, and the associated files, are included in the Terrain Height Estimates file:on the enclosed CD.
-Since there -are no severe terrain features such as deep valleys or mountains,.in the vicinity of NMPR.to affect the diffusion, of radionuclides releases from the *elevated main stacks, the default terrain adjustment factors .(TAF=l) were applied..
5.24., Identical Data For the reasons mentioned in Sections 5.2.1* and 5.2.2, several of the PAVAN inputfiles, with the exception of file name, have the same inputdata and assumptions. For this reason, several of these files are omitted from Table 5.1-1. Input reference files identical to these
.omitted input files are providedin Table: 5.2-1. Likewise, the output files for those.mentioned in Table 5.2-1 are alSo assumed Io be identical to their reference output files and are therefore not included in this report. These files, bothinput and output, are: however contained in the respective InpUt Files or Output:Filesfolders. on the enclosed CD.
5.2.5. Maximum Category 12 Wind Speed Since the NMP meteorological data (Reference 9) fails to provide a maximum wind speed for category 12 winds, a conservative value of 60.5 m/s was selected., Maxmum Wind speed is required. input for each wind category!in PAVAN.
5.2.6. NMP Unit 2 WSW Sector The NMP Unit 2WSW sectordistance tob;theEAB maybe considered as.a land or: castal distance (Reference 11). This calculation uses land distances to the EAB from the Main Stack and Combined Radwaste/Reactor Building of 1A,615 m and 1.,381 m, respectively.

.Forstack releases, the maximum ground-level X/Q. in a sector may occu r at a distance beyond the EAB and LPZ. R;G. i.;145 (Reference 2), recommends making X)Q calculations for each sector at each: minimum boundary distance and at various distances:beyond the EAB to determine where the maximum concentrations occur. Test cases in PAVAN were performed
.at both Units for the following distances (in meters):
1W0 250 .500 510 !525 535 550 *600 650 700 1750 850 1000 1250 1500

6.2. ENVLOP Programming:Error:
As. mentioned in the CNS .PAVAN Computer Code Verification (Reference 15), the PAVAN ENVLOP subroutine has, a programming error*or "bug." As a result.. 0.05% X/Qs for non-coastal sectors were visually checked, in each. PAVAN output.*file. Twenty-eight: cases were hand-checked where th e .0.5% )JQ was not, bounded, or near neigh"boring, points . These cases included:

These values represent Page 16.of.4 5

Date: Dec. 19,20032 Nuclear Services the.*0 -2hour X/Qs for the-sector. It was determined that all 1the 0.5% X/Q values were calculated correctly: by PAVAN, and are therefore valid. Hence, the PAVAN outputvalues were extracted and required no.additional processing. These calculations are included in'the 0.5%,Sector Dependent Calculationsfolder on the attached disc.
6.3. ENVLOP Error According to the PAVAN user's guide (Reference8), an error occurs in the ENVLOP subroutine when the total number of values in the arrays X and Y used in obtaining upper-enveloping lines exceeds 98. This number overflows arrays .X and Y. As a result of:this error, the overall site XQ value which is equaled or exceeded 5.0% of the time was notobtained .in six of the PAVAN calculation runs.

Rev.2 NuclearServices Date: December 22,2003 1,. Objective The purpose of this calculation-is to determine conservative estimates of atmospheric
,dispersion coefficients (X/Q) for the Nine Mile Point Unit 1 and 2 Nuclear Station control room air-intakes for release pointsdefined herein.
2. Background
Nine MilefPointNuclear Station (NMP) hasrequested the services ofConstellation Nuclear Services'(CNS) to evaluate and update offsite-and control room atmospheric dispersion
.coefficients for, Units 1 and 2. The atmospheric dispersion coefficients (X/Q) are needed for a scoping study to determine the feasibility of the use of Altemative Source Term (AST) methodology for the determination of design basis accident dose consequences and can be applied to other calculations which, determine :radiation dose consequences at the Unit-1 and 2 Control Rooms, 2.1. Applicable Regulations and Commitments This calculation employs the ARCON96 computer code (Ref. 2) to:.calculate XIQ values. The Regulatory Guides (RG) 1.145 (Ref. 3) and 1.183 (Ref. 4) are utilized to ,perform the analyses herein. Other regulatory guidance on atmospheric relative concentrations for *Control Room radiological habitabilityassessments (Ref- 5) has been implemented as necessary. The regulatory guidance foranalyses associated with the useof AST is found in RG 1.183 (Ref. 4).
Meteorological data are hourly averages obtained from NMP Joint Frequency Distribution
.Report (JFD) (Ref. 29) and the analysis conforms to the requirements, of R.G. 1.23 (Ref.30).
- 3. Methodology Recently published guidance (Ref. 4 and 5) has outlined acceptable procedures for calculation
,of X/Q values With the computer code system ARCON96. ARCON96 employs a straight-line Gaussian dispersion model to calculate X/Q values based on hourly meteorological data. The X/Q values calculated are ýhourly, normalized concentrations. These values are then averaged to provide X/Q values for time periods ranging from 0 to 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br />. A more complete discussion, including details on the methods, input guide and programmer's guide, are provided in'the user's guide (Ref. 2).
The ARCON96 computer.code was utilized to calculate conservative estimates of the XIQ values for all releases to eachof the NMP Unit 1 and 2 Control Room intakes and the.Unit I Technical Support Center. The recently published guidance (Ref. 5) was reviewed and used as appropriate. Moreover, the details pertaining tothe use of ground level, vent and stack
- releases, calculation of building wake correction factors, appropriate ARCON96 default input and the use of diffuse area sources were considered for inclusion.

- 4. Computer Hardware/Software Usage 4.1. Description of Hardware Used 98 and Windows 2000 personal Allcomputer calculations were performed on Windows computers. The computer identification of the PCs used are CNS-1:15 and CNS-1 12.
4.2. Description of Software Used The ARCON96 computer code system was used to calculate control room X/Q values.
ARCON96 is an:NRC affiliated computer code which implements a straight-line Gaussian dispersion model to estimate downwind X/Q values. The X/Q values are determined from hourly meteorological data. ARCON96 has the capability to calculate ground-level, vent or stack release scenarios. A complete description of the code, including its capabilities, technical basis and programmer's guide can be found in the user's guidef(Ref.2).
Microsoft Excel was utilized to calculate distances and directions for release/intake scenarios bnot readily available by reference.
4.21.. Software Verification ARCON96 has been verified and validated (Ref. 6) in accordance with Quality Assurance procedures (Ref. 7). Microsoft Excel is classified as.Category 3 Software per section:3.2.3 of the CNS Computer Code Verification 3.5 (Ref. 7) and does not require initial verification.
The results obtained from use of Microsoft Excelwereverified in the same manner as technical reportsW(Ref. 7).

- 1. North-south :dimension of Unit I Turbine Building = 116'5" 35.48 meters (Ref. 23).
This assumption is taken to approximate the dimension of the. Unit 1 Turbine Building for the purposes of calculating the building wake area.
- 2. East-west dimension of Unit 1 Turbine Building= 2x(23' 6") + 14x20' =327'= 99.67 meters (Ref. 23). This assumption lis taken to approximate the dimension of the Unit 1I Turbine Building foreTthe purposes of :calculating the building wake area.
3;. Unit I Control Room intake height: above grade = 333' - 261' = 72'.- 21.95 meters.
(Ref. 24) Assumes the intake height is equal to roof elevation, This assumption is taken .to approxi mate the height of the intake as it is not apparent from the .references.
- 4. PASS Panel Vent release height above grade = 339' +4' (curb) - 261' = 82' =25
- meters. (Ref. 25) Assumed to include 4' high conicrete-curb surrounding the vent location. This assumption istaken to approximate the vent release height as it is not apparent from the references.

- 5. Unit.1 releases to Unit 1 Control room intake building wake area is consetvatively assumed to be equal to :one half of the east-west Unit 1 Turbine Generator Building cross-sectional area. This assumption is to account for the complexity of the dense building:cluster at the NMVP site for Which it,'is difficult to accurately characterize the building wake area., This assumption conservatively results in higher X/Q values.
- 6. Unit 1 releases to Unit 2 Control Room intakes buildingwake area is conservatively assumed to be equal to north-south cross sectional areapof the Unit,2 Turbine Building.
As the building wake area is difficult to accurately characterize, this assumed area is a best estimate. The actual cross sectional area from the release point to the receptor may be slightlylgreater than the value determined from this assumption. Therefore, this assumption conservatively results in higher X/Q values.
- 7. Unit 2 releases to Unit 1. Control Room intake and Unit I Technical Support Center, with the exception of the Unit 2 Main Stack release, building wake area is conservatively assumed to be equalto north-south cross-sectionaelarea of the 'Unit 2 Tur(bine Building.
As the building wake area is difficultto accurately characterize, this assumed area is a best estimate. The actual[ cross sectional area fromltherelease point to the receptor may be slightly greater than the value determined from this assumption. Therefore, this assumption conservatively resuIts; in higher X/Q values.
- 8. Unit 2 Standby Gas Treatment System Building and Unit 2 Main Stack releases to Unit, 2 Control Room intakes building wake area is conservatively assumed to be equal to the Unit 2 Reactor Building cross-sectional area. This assumption is taken since the Unit 2 Reactor Building is the dominant structure between the release point and the receptor location. This assumption is conservative because the actual building wake area may be larger due to neighboring structures.
- 9. Unit 2 Combined Radwaste & Reactor Building Vent and Main Steam Tunnel releases to Unit 2 Control room intakes building wake area is assumed to be 0.01 m2 (Ref. 5)for a zero wake term. This assumption is made because the Combined Radwaste &
Reactor Building Ventland Main Steam Tunnel release points are in close proximity to the, intakes. In this configuration it is difficult to characterize the building wake area and assure a conservative X/Q estimate. A zero wake term assumption conservatively results in higher X/Q values.
- 10. Unit 2 PASS Panel Vent release to Unit 2 Control room intakes building wake area.is conservatively assumed to be equal t0 one half of the Unit 2 Reactor Building cross-sectional area. This assumption.is to account for the complexity of the dense building cluster at the NMP site for which it is difficult to accurately characterize the building wakeiarea. This assumption conservatively results in higher X/Q values.
- 11. Unit 2 Main Stack-release is assumed to be a ground-level release as opposed to a stackrelease in ARCON96, This assumption is made because the NMP stacks are generally located in close proximity to the site building cluster.. The height of the stacks Page9 of 37
Constilatin 44Calculation No: NMPA$T-024.01 Rev.2 Nuclear Se, ces Date: December 22, ,2003 are close to or below 2.5 times the height-of the site building structures. Also, regulatory guidance documents (Ref. 5) indicate that prope'rqualification of stack configurations must be made in orderto assume a stack release. Therefore, to alleviate the regulatory risk and to assure conservativeX/,Q estimates, this assumption has been made. The X/Q results from this assumption Will be. conservatively higher than those calculated as stack release.
- 12. Unit 1 Turbine Building Blowout panel release to Unit 1 Technical Support Center
.building wake area is conservatively assumed to be equal to the north-south Unit 1 Turbine Building Generator Building cross-sectional area. As the building wake area is:
difficult to accurately characterize, this assumed area is a best estimate. The actual cross sectional areafrom the, release point to the receptor may be slightly greater than the value determined from this assumption. Therefore, this assumption conservatively results in higher X/Q values.
- 13. Unit I Main Stack and Reactor Building Blowout Panel releases to Unit I Technical:
Support Center-building wake area is assumed to be 0.01 m2 (Ref. 5) for a zero wake term. This assumption is made because the release points are in: close proximity to the intakes. In this configuration itis difficult to characterize the building wake area. A zero wake term assumption conservatively resultsjin higher X/Q values.
- 14. Elevation change from the mid-point of the Unit 1 Turbine Building Blowout Panel to Unit I Technical SupportCenter is 62' or 18.9 meter (Ref. 18)1.The-elevation of the mid-point of the Unit 1 Turbine Building Blowout Panel is approximately (354' + 334') 12
-261' = 83" according to Reference 10. Therefore, the elevation of the Unit 1 Technical Support Center is assumed to be 83 - 62' = 21' = 6.4 m. This assumption is taken in lieu of a clear reference showing the height of the Unit 1 Technical Support Center intake structure.

.7.1'. Releaselintake Distances and Directions Calculations Table 5.2.1 list the distances and-directions provided in the X/Q calculations performed
'previously by MES. These MES calculations fail to provide the distances and sector bearings for the following releases to the Unit 2 Control Room intakes: (1) Unit 1 Reactor Building blowout panel, (2) Unit I Turbine Building blowout panel, (3) Unit22Main Steam Tunnel, (4)
Unit 2 Combined Radwaste & Reactor Building Vent, (5) Unit 2 PASS Panel vent and (6) Unit 2 Standby Gas Treatment Building vent. Furthermore, the MES calculations also fail to disclose the distances and bearings for the Unit 2 releases to the Unit 1 Technical Support Center. The data listed in Table 5.2.1 was used to calculate the distances and directions for the above releaselintake combinations by developing a coordinate system. The Unit 2 Main Stack: release point was defined as the origin. :Figure 7.1.1 shows a schematic depicting the coordinate system used. The.coordinate axes, x and y, were respectively aligned with'the "true north" and "true east."

Building Wake Areas Dueto the complexity of the geometry of the-structural buildings for both Units i and 2, conservative building wake-areas were calculated. Theconservative assumptions taken to calculate the wake areas:are stated in 5 through 10, 1,2 and 13,of Section.6.1. The calculations for determining building wake areas are as follows:
Unit I Releases to Uni't I Control Room Intake Per assumption 5 of Section 6.1, the contributing building area is conservatively assumed to be one half of the east-west cross-sectional area of the Unit 1 Turbine Generator Building.

- 73. X/Q Values The ARCON96 input is comprised of release/intake specific data and some default input parameters, The ARCON96 user's guide (Ref. 2:).provides the details of the default input data.
All releases have been treated as ground-level releases, including both stack: releases.
Regulatory guidance (Ref. 5) suggests the use of stack release mode in ARCON96 when the
,release.point is greaterthan 2.5.times the height of adjacent build ings. Following this specification the Unit 1 stack release is clearly considered a ground-level release. The Unit.2 Main Stack is only slightly greater then 2.5 times the Unit.2 Reactor Building. Since ,this guidance (Ref. 5) suggests that ARCON96 can calculate non-conservative X/Q values in stack release-mode and given the consideration that the Unit 2. Main Stack is very close to 2.5 times the Unit 2 Reactor'Building .height, the mode of release provided in the ARCON96 for all Unit'2 Stack releases is ground-level. This is consistent with assumption 11 above inSection 6.
The diffuse area:source as described in the regulatory guidance (Ref. 5)-was also considered for the Unit I Turbine Building and Reactor Building blowout panel release scenarios.
ARCON96 runs were: performed using the diffuse area:source input for ARCONg6 (as describedin Ref. 5). The results suggest thatthe values calculated with the diffuse-area source are slightly less conservative than the values calculated by considering the blowout
'panels as a finite :point. Therefore, :no diffuse area sources have been implemented in the ARCON96 runs.
ARCON96 requires the direction data fordeach release/receptorto be'input asthe direction ffrom the intake to the release. To this point, the directions listed above in Tables 5*2.1 and 7.1.2 were inverted by 180 degrees. The final distances and directions..are provided in Table 7.3.1.
The input common to all runs.is comprised mainly of default data. The: regulatory guidance (Ref. 5) also provides guidance on values of default input data. The values specified in the regulatory guidance (Ref. 5) were usedinstead of those provided in the ARCON96 user's manual (Ref. 2). Table 7.3.2 lists.the ARCON96 common or default input that was used and the reference for that input data.
A representative input file is included in Appendix A. Due to the number of computer runs perforrned the'input and output files have been, provided on the enclosed CD. Appendix C provides a list of computer runs and Appendix D provides a listing of:all files on the enclosed CD.
Table 7.3.3-1 providestabular results of the.X/Q values for all releases to the Unit I ,Control Room ýand Table,7.3.3-2 provides results of the :X/Q values for all releases to the Unit 1 Technical Support Center. Table 7.3.4 provides tabular results ofthe X/Q values for all releases to the Unit 2 Control Room.
The results presented in Tables 7.3.3-1 through 7.3.4 are based on revised meteorological data (Refs. 27 and 28.).

Conclusions:
Atmospheric dispersion coefficients (X/Q) values have been calculated at the conitrol room intakes at both :Units 1 and 2 and the Unit 1 Technical.Support Centerdue to all postulated release scenarios. Tables 7.3.3-1., 7.3.3-2 and 7.3.4 provide conservative X/Q-values for the
,scenarios listed above.

Nine Mile, Point Nuclear Station Design Verification ofCalculations N NMPAST-O1-OOl and NMPAST-02.001 NISYS-1169-DVOO1RO 1.0 OBJECTIVE Theobjective of this report is to perform a design verification of Nine Mile Point:Nuclear Station (NMP) calculations NMPAST-01-001, Rev. I (Ref. 1) and NMPAST-02-001, Rev.
1 (Ref. 2).
Using the PAVAN *computer program (Ref. 3), calculation NMPAST-01 -001 determines
.the atmospheric dispersion coefficients (X/Q values) at the exclusion area boundary (EAB) and low population zone (LPZ).boundary, due to releases from specified Unit 1 and Unit 2 sources. Calculation NMPAST-02-001 uses theo ARCON96 program (Ref. 4) to determine the .X/Q values for the NMP;Unit 1 and Unit 2 fresh air intakes, due to releases
,from specified Unit 1 and Unit 2 sources. Atmospheric dispersion coefficients are needed to perform Alternative Source Term scoping calculations, which are documented
- elsewhere..

5), and in NISYS Corporation's Project Instruction (Ref. 6). The design review method, as defined in Reference 5, will be used to perform the verification of calculations NMPAST-01-00i and NMPAST-02-001...
The extent of the design review will include identification of the design input, calculation process, and output for the subject calculations. The design review will also evaluate the appropriate use.of the PAVAN and ARCON96 software to accurately determine the X/Q values. In addition, the following questions wjillbe addressed (as required by References 6 and 7) to ,ensure: that relevant items are considered in the verification effort:
- 1. Were the inputs correctly stated?
- 2. Are the assumptions necessary to perform the calculations adequately described and reasonable?
- 3. Was an appropriate method used?
.4. Were the inputs correctly incorporated into the calculations?
- 5. Are the outputs reasonable compared to the inputs?
- 6. Do the :calculations conform to USNRC Regulatory Guides 1.145 and 1-.194?
The results of the design review are discussed .in Section 4.0. Completed ýdesign verification criteria sheets as required by
Reference:

Were the inputs correctly selected? X 1a. 6In MPAST-O1 .001, the EAB distances from Unit 1 and Unit 2 for the E, ESE, and SE sectors may be in error, since, as defined below, the Exclusion Area should include NMP-controlled property: only. These distances appear to be measured to the eastern boundary of the neighboring Fitzpatrick site (i.9 and 1.6 km for, Units 1 ýand 2, respectively forthe E sector), rather than to the eastern boundaryof the.
NMP site (approximately 0.7 km for Unit 11(Ref. 12)).
Per 10CFR100.3, Exclusion area is defined as "that area surrounding the reactor, in which the reactor licensee has the authority .to determine all activities including exclusion or removal of personnel and .property from the area. This area may be traversed by a highway, railroad,:oir waterway, provided these are not so close to the facility as :to interfere:
with normal -operations of the facility and provided appropriate and effective arrangements are made. to control traffic on the highway,
-railroad, or waterway, in case of emergency, to protect thepublic health and safety. Residence within the exclusion area shall :normally be prohibited. In any event, residents shall be subject to ýready removal in
ýcase of necessity. Activities: unrelated to operation of the reactormay be permitted in an exclusion area under appropriate limitations, provided that no significant hazards to-the public health and safety will result."
7lb. Although the values-used for design inputs are referenced I(in,Section 5.1 of the calculation), for clarity of the geographic relationships it is recommended that the calculation include a scale drawing that shows: a compass "rose" superimposed upon an outline of the extent of: the EAB and LPZ. Alternatively, it is recommended: that the appropriate figures from the references be included as attachments-to the calculation.
11c. The source of the meteorological inputs is clearly specified in Section
.5.1 of the calculation. However, the method used to obtain these inputs from the raw data is .not stated. Section 1.1 of Regulatory Guide 1.145 requires that meteorological data represent hourly averages, and are categorized into atmospheric stability classes according to Regulatory Guide 1.23 (now Safety Guide 23), 'Onsite Meteorological Programs". It is recommended that a statement documenting conformance to Safety
'Guide 23 be included.

Document: NMPAST-01 -001, Rev. 1 Review Check Items Addressed with Basis of Review Answer Yes -No N/A 2, Are the ,assumptions necessary to perform the calculations X adequately described and reasonable?
2a. In Section 5.2.2 of NMPAST-01 -001 , thedivalue used for the variable A,
'the minimum' vertical *cross-sectional area of the Unit :1 containment structure (2082 M2), could not be verified. As a check, the height:of the Unit 1' Reactor building is 42.2 m (Table :5.1-1.b of NMPAST-01-001),
and the horizontal dimension of the Ul RB-TB complex (east-west) is 99.67 m (Sect. 6 of NMPAST-02-001), yielding a cross-sectional area of approx. 4186 im2, The inputs for this assumption and a justification should be clearly stated. '(For example, "Although the actual cross-sectional area is __ m2 ,found by multiplying a height of - m by length
,of __ m, a smaller area is assumed because the reactor building is connected to other buildings and this conservatively results in higher X/Q values.)
- 3. Was an appropriate method used? X 3a. In Section 6.2 of NMPAS!-o1-001, the reason for hand-checking 28 sector 0.5% X/Q values is not clear. (Recommend that an example beýý provided to clarify the screening process!) Of these 28.° cases, 26 resulted in 0.5%.X/0 values' identical to the PAVAN output. However, the X/Q values subsequently.,calculated for the intermediate .time intervals differ from the PAVAN output. The differences are small (on the order of
.1%) and are apparently due to calculating the intermediate time~intervals using 3 significant digits (handccheck values) instead of 4 (PAVAN values).
3b. Of the 28 hand-checked cases discussed in Section 6.2 of NMPAST '001, -.two.,cases resulted in a change to the reported value (from 2.048E-6 to 2.08E-6 for Unit 1 Main Stack to LPZ-E, and from 9.140E,5 to 9.58E-5 for Unit 2 Combined Vent to EAB-WSW), These modifications, which are conservative, appear to be due to differences between PAVAN and the hand-check procedures that derive. the upper envelope of the X/Q values versus their cumulative frequency of occurrence. :For the PAVAN approach,: :Section 4.6 of NUREGICR-2858 states, "Starting with the highest X/Q value, [subroutine] ENVLOP compares the slope of the line drawn from this point to every other point within an~increment containing ten X/Q values." The FORTRAN listing was checked to verify that ENVLOP uses only ten points in each increment,'thereby calculating the slopes ofnine lines. In contrast, the EXCEL spreadsheets that document the manual 'procedure use eleven points per increment, resulting in ten slopes.
3c. In Sections 6.2 and 6.3 of NMPAST-01-001, when calculating the intermediate time-period X/Qs using Alogarithmic interpolation, it is recommended that the basis for using the,selected time points of 8, 16, 72 and 624 hours0.00722 days <br />0.173 hours <br />0.00103 weeks <br />2.37432e-4 months <br /> (as shown in the Intermediate Time Calculations spreadsheets). be stated.

1., Were the inputs correctly selected? X 1a. Although the values uised for design inputs are referenced (in Sections 5.2 and 7.1 of the calculation), for clarityof the geographic relationships.
it is recommended that the calculation include a scale drawing that shows a compass "rose" superimposed upon an outline of the Unit 1 and
- Unit 2 showing the release points and intakes. Addtionally, it is recommended that the appropriate tables and figures from the references be included as attachmentslto the calculation.
l b. The. source of the meteorological inputs Jis clearlY specified ,in Section 5A1 of ýthe calculation. However. the method used to obtain these inputs from the raw data is not stated. Section 3.1 of Regulatory. Guide 1.194 requires :that meteorological data *represent hourly: averages, and are categorized into atmospheric stability classes according to Safety Guide 23 (formerly Regulatory Guide 1.23), "Onsite Meteorological Programs".
It is recommended that a statement documenting conformance to Safety Guide 23 be included.
- 2. Are:the assumptions necessary to perform the calculations X adequately described and reasonable?
2a. In Section 6, the justification for all assumptions should'be-clearly stated.
For example, "Unit "1releases to Ul OR intake building wake area is assumed to be one-half of the E-W U0 TB cro.ss-sectional area because
[give reason] and this conservatively results in higher X/Q values."
As another example, "U2 Main Stack release isaassumed to. be a ground-level release in ARCON96 because [give reason], as described in Section 7.3."
- 3. Was an appropriate method: used?

- 4. Were the inputsvcorrectly incorporated into -thecalculations? X 4a. :In NMPAST-02-001, three conversions from English into metric:units are incorrect. In Section 5.4, the Unit 2 :RB outer radius (85' 6") should be
.26,06 m (not 25.06im). In Section 6, the:Unit 1 TB E-W dimension (327')
-should be 99.67 m (not 111.86 m), and the Unit 1 CR intake height above grade (72') should be 21.95 m (not 29.95 m). These errors are carried forward into Section 7.2, resulting in six errors in the Table 7.2.1 Building Wake Areas; Unit 1 (all) to Unit 1 CR should be 550. not 167 M2 .
U2:(all except stack):to Ul CR should be 623 not 281 m2 2
U2 stack to Ul CR should be 2165 not 1363 i U2 stack :to Ul TSC should be 3639 not 3549 M:.
2 U2 stack & SGB to U2 CR (all), should be 1844 not 1773 mn :
U2 PASS to U2 CR (all);should be 922 not 886 in2 .
The errors were carried forward into the ARCON96 computer runs.
- 5. Are the: outputs reasonable compared to the inputs? X 5a. Although the ARCON96 computer .input files, output files and Excel worksheets that are described in 'the each of the, calculations :are provided on aread-only CD (Ref. 11), it,is recommended that a detailed
.listing of the files be provided. This will assure that the files available on
