CALCULATION NO. DRE04-0030 I REV. NO. I I Page 4o f lS 1.0 PURPOSE/OBJECTIVE This calculation, DRE04-0030, Rev. I, presents the atmospheric relative concentration (X/Q) values for Alternative Source Term (AST) accident evaluations for the Dresden Station. The purpose of this calculation is to determine the Control Room, Exclusion Area Boundary (EAB), and the outer boundary of the Low Population Zone (LPZ) relative concentration values (X/Q, in sec/r 3 ) resulting from certain postulated accidental radiological releases. The values resulting from this calculation will serve as input to the calculation of the radiological doses using Alternative Source Terms (AST) per Regulatory Guide (RG) 1.183 (Reference 1).

The X/Q values resulting at the Control Room Intake are calculated using the NRC-sponsored computer codes ARCON96 (Reference 2) and PAVAN (Reference 3) consistent with the procedures in RG 1.194 (Reference 4). These analyses are presented in Section 2.0 (ARCON96) and in Section 3.0 (PAVAN).

The X/Q values resulting at the EAB and LPZ are calculated using the NRC-sponsored computer code PAVAN, consistent with the procedures in RG 1.145 (Reference 5). This analysis is presented in Section 3.0.

2.0 ARCON96 ANALYSIS OF CONTROL ROOM X/Q ARCON96 is a commercial software package designated by Washington Group International (WGI) as NU-830, an "active" program applicable to nuclear safety related analyses as well as non-safety related studies and evaluations. Its use is principally control room habitability assessments. The NU-830 code has been verified for 0-2 hour, 2-8 hour, and 8-24 hour centerline and sector X/Q averages and the 95%

maximum X/Q. This verification is in accordance with Revision 4 of the WGI Nuclear Engineering Standard for Computer Software Control, NEP-09. Revision 0 of NU-830 was verified for ground-level and zero exit velocity uncapped vents, and Revision 1 was verified for zero exit velocity stack releases.

2.1 Methodology and Acceptance Criteria ARCON96 Program Description [excerpted from NUREG/CR-633I Rev. 1]

ARCON96 is a straight line Gaussian dispersion model used in control room habitability assessments for estimating dispersion in the vicinity of buildings to calculate relative concentrations at control room air intakes that would be exceeded no more than five percent of the time. The basic diffusion model implemented in the ARCON96 code is a straight-line Gaussian model that assumes the release rate is constant for the entire period of release. This assumption is made to permit evaluation of potential effects of accidental releases without having to specify a complete release sequence. Ambient atmospheric conditions measured in accordance with RG 1.23 (Reference 6) are input to ARCON96 by way of a sequential hour-by-hour meteorological database ofjointly measured wind speed, wind direction, and Pasquill stability class, as derived from the vertical temperature difference recorded at a representative location and elevation (i.e., tower level).

ARCON96 permits evaluation of ground-level, vent, and elevated releases. Building wake effects are considered in the evaluation of relative concentrations from ground-level releases. The proportion of the mixture is determined by the ratio behveen the effluent vertical velocity and the release-height wind speed using the procedure included in the NRC XOQDOQ code (Reference 7).

I CALCULATION NO. DRE04-0030 l REV. NO. I I Page5of 1 An elevated release, defined as a stack more than 2.5 times the height of structures in the immediate vicinity, is treated in the usual manner with correction for stack downwash and differences in terrain elevation between the stack and the control room intake. With an assumed zero (0) vertical exit velocity, vents are treated as ground-level releases. Otherwise, a vent release is treated as a mixed ground-level and elevated release.

Diffusion coefficients used in ARCON96 have three components. The first component is the diffusion coefficient .used in other NRC models, for example XOQDOQ, and PAVAN. The other two components are corrections to account for enhanced dispersion under low wind speed conditions and in building wakes.

Derivations of the low wind speed and building wake corrections are described by Ramsdell and Fosmire (Reference 8).

Parameter values for the correction factors are based on analysis of diffusion data collected in various building wake diffusion experiments. The experiments were conducted under a wide range of meteorological conditions. However, a large number of experiments were conducted during low wind speeds, when wake effects are minimal. The wake correction model included in ARCON96 treats diffusion under these conditions much better than previous models. Thus, the diffusion coefficients in ARCON96 account for both low-wind speed meander and wake effects.

ARCON96 calculates relative concentrations using hourly meteorological data. It then combines the hourly averages to estimate concentrations for periods ranging in duration from 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months to 30 days. Wind direction is considered as the averages are formed. As a result, the averages account for persistence in both diffusion conditions and wind direction. Cumulative frequency distributions are prepared from the average relative concentrations. Relative concentrations that are exceeded no more than five percent of the time (9 5th percentile relative concentrations) are determined from the cumulative frequency distributions for each averaging period. Finally, the relative concentrations for five standard averaging periods used in control room habitability assessments are calculated from the 95th percentile relative concentrations.

2.2 Design Input 2.2.1 Source/Control Room Intake Scenarios There are four (4) release points identified for Dresden: the Unit 2 MSIV, the Unit 3 MSIV, the Station Chimney and the Reactor Building Vent Exhaust Stack. Both the Unit 2 and Unit 3 MSIV release heights are assumed to be 0 m above grade elevation since the releases actually occur below grade. The Station Chimney has a release height of 94.6 m and the Reactor Building Vent Exhaust Stack has a release height of 48.6 m (Reference 9). The Unit 2 MSIV, Unit 3 MSIV and the Reactor Building Vent Exhaust Stack are all less than 2.5 times the height of their adjacent buildings, and therefore per RG 1.194 they are modeled as "ground" level releases. Consistent with the original Dresden Station licensing as documented in the Dresden SER, the Station Chimney (although somewhat less than 2.5 times the height of its adjacent buildings) is treated as an elevated release. The locations of the Unit 2 MSIV, Unit 3 MSIV, and Reactor Building Vent Exhaust Stack can be seen in Attachment A and the location of the Station Chimney in Attachment B.

The Control Room Intake is located 11.3 m above grade as seen in Attachment C, and is identified with respect to the MSIV and Vent Exhaust Stack in Attachment A and the Station Chimney in Attachment B.

ARCON96 is executed for each of the following Source/Control Room Intake scenarios:

1) Unit 2 MSIV to Control Room Intake

I CALCULATION NO. DRE04-0030 I REV. NO. I Page6of15

2) Unit 3 MSIV to Control Room Intake

3) Station Chimney to Control Room Intake

4) Reactor Building Vent Exhaust.Stack to Control Room Intake.

Per RG 1.194 Table A-2, the building area perpendicular to the wind direction should be utilized in ARCON96. For the Unit 2 MSIV, Unit 3 MSIV, and Reactor Building Vent Exhaust Stack scenarios, the Reactor Building cross-sectional area was utilized. For the Station Chimney scenario, the Turbine Building

_ area was utilized-Calculations of these building areas are shown in Attachment D. _ _

The source in all modeling scenarios is treated as a point source. The ARCON96 input parameter values were set in accordance with RG 1.194, Table A-2 (e.g. surface roughness length = 0.2 m; wind direction window = 90 degrees, 45 degree on either side of line of sight from source to receptor; minimum wind speed = 0.5 m/s; and averaging sector width constant = 4.3).

The Station Chimney to Control Room Intake scenario was modeled in ARCON96 in Rev. 0 of this calculation without considering the effects of stack downwash (i.e. the vertical velocity, stack radius and stack flow were set to zero). In response to the NRC RAI dated July 22, 2005, additional ARCON96 model runs were completed with downwash incorporated by setting the vertical velocity (derived from the stack flow divided by the stack top internal area), stack radius (to the outside edge at the stack top) and stack flow (the design Standby Gas Treatment System flow) to 0.21 m/s, 1.86 m, and 1.89m3 /s, respectively, based on values indicated in the Dresden UFSAR.

Other parameters utilized by ARCON96 (i.e. wind direction, horizontal distance, etc.) are contained in Attachment E.

2.2.2 Meteorological Data The Dresden meteorological tower data for the five-year period, 1995-1999, as supplied by Exelon (Reference 10), were applied in the ARCON96 modeling analyses. Wind measurements were taken at 35 ft, 150 ft, and 300 ft. The vertical temperature difference (i.e., delta T) was measured between 150 ft and 35 ft and between 300 ft and 35 ft. Wind speeds reported as "calm" were assigned a value of 0.5 mph (i.e.

0.22 m/s). As stated in Section 2.2.1, however, ARCON96 assigns a default value of 0.5 m/s to each wind speed lower than 0.5 m/s.

Executing ARCON96 requires the meteorological input file to contain two (2) wind levels (lowver and upper) and one (1) delta T stability class. Since the Dresden X/Q analysis necessitates the modeling of both ground-level and elevated sources, two ARCON96 meteorological databases were developed from the three (3) levels of wind measurements (i.e. 35 ft, 150 ft, and 300 ft) and the two (2) sets of delta T measurements (i.e. 150-35 ft and 300-35 ft) as follows:

NO.1 Page 8 of 15 3.0 PAVAN ANALYSIS OF CONTROL ROOM, EAB and LPZ X/Q The model PAVAN is a commercial software package designated by WGI as MC-131, an "active" program applicable to nuclear safety related analyses as well as non-safety related studies and evaluations.

The PAVAN code Revision I verification was performed for the 0-2 hour, 0-8 hour, 8-24, 1-4 day, and 4-30 day 0.5-percentile, and annual average direction-specific X/Q values, and the overall site 95-percentile

maximum-X/Q-for-each of the 0-2-hour, 0-8 hour, 8-24 hour,-1-4.day, and 4-30 day time-averaging periods. This verification was performed with WGI (formerly Raytheon Engineers & Constructors, Inc.)

corporate standards, and is consistent with Computer Software Control, NEP-09. Revision 1 of MC-131 was verified for ground-level (i.e., non-elevated) releases, as well as elevated releases, with zero (0) vertical exit velocity assumed.

While its use is principally for EAB and LPZ X/Q evaluations, PAVAN is also referenced for use in accordance with NRC RG 1.194 methodology for control room habitability assessments of elevated releases. In supplement to the use of ARCON96 for this purpose, NRC recommends that PAVAN also be executed, and its results incorporated into the determination of the 0-2 hour, and the 1-4 and 4-30 day X/Q time intervals. The maximum PAVAN X/Q at ground-level (excluding the "fumigation" condition) replaces the corresponding ARCON96 0-2 hour value if the PAVAN value is greater. For deriving the.

two longer interval X/Q values, the maximum PAVAN 14 day X/Q is added to the product of 23 times the maximum 14 day ARCON96 value, and then the total is divided by 24, resulting in the final X/Q value for the 1-4 day interval value; and similarly, the maximum PAVAN 4-30 day X/Q is added together with the product of 23 times the maximum 4-30 day ARCON96 value and then divided by 24 to obtain the X/Q value for the 4-30 day interval value.

3.1 Methodology and Acceptance Criteria The computer code PAVAN is a straight line Gaussian dispersion model utilized to estimate relative ground-level air concentrations (X/Q) for potential accidental releases of radioactive material from nuclear facilities. Such assessment is required by .10 CFR 100 and 10 CFR 50. The program implements the NRC guidance provided in RG 1.145. The technical basis for the program is presented by Snell and Jubach (Reference I1). Utilizing joint frequency of occurrence distributions of wind direction, wind speed and Pasquill atmospheric stability class, PAVAN calculates X/Q values as a function of direction for various time-averaging periods at the EAB and the outer boundary of the LPZ. Calculations are made from assumed ground-level (i.e., non-elevated) releases (such as vents and building penetrations), which are less than 2.5 times the height of adjacent solid structures, and from elevated releases (i.e., stacks). Three (3) procedures are utilized for calculating X/Q: a direction-dependent approach, a direction-independent approach, and an overall site X/Q approach.

The PAVAN model contains certain model options for executing the program. Table 3-1 below summarizes the options invoked for the Control Room, EAB and LPZ X/Q calculations.

3.2 *Design Input 3.2.1 Source/Receptor Scenarios 3.2.1.1 Control Room Intake For the Station Chimney to Control Room Intake scenario, PAVAN was executed in elevated release mode. The stack-to-intake horizontal distance is 81 m. The release height of the Station Chimney is 94.6 m, however, RG 1.194, Section 3.2.2 requires the release height to be measured from the height of the Control Room Intake (11.3 m above grade elevation); therefore, the actual Station Chimney release height of 94.6 m above grade was reduced by 11.3 m, to 83.3 m for modeling. Other PAVAN input parameter values included the Reactor Building height of 43.1 m (Reference 9) and the minimum Reactor Building vertical cross-sectional area of 1545 m2 .

Following the execution of PAVAN for the distance from the Station Chimney to the Control Room Intake, a review of this output was performed in accordance with RG 1.194 guidance to estimate an approximate distance range within which the actual maximum 0-2 hour X/Q would be predicted to occur in each given downwind sector. An additional set of PAVAN runs was then executed for several distances in this range. The distances modeled to determine the actual maximum X/Q are as follows: 75, 81 (actual), 100 150, 200, 300, 350, 375, 400, 425, 450, 600, 800,1000, 1500, 1800, 1900, 2000,;2200, 2500, and 3000 meters.

Terrain was not considered for the Station Chimney to Control Room Intake scenario because the distance from intake to source is so small that the terrain would not be expected to have a significant effect on the X/Q values.

3.2.1.2 EAB and LPZ The PAVAN model was also executed to determine the ground-level X/Q for the following source/receptor scenarios:

CALCULATION NO. DRE04-0030 l REV. NO. I l Page 10of 15l

1) Unit 2 and 3 MSIV to the EAB and LPZ

2) Station Chimney to the EAB and LPZ

3) Reactor Building Vent Exhaust Stack to the EAB and LPZ The EAB and LPZ are located at 800 m and 8000 m, respectively. The MSIV release points and the Reactor Building Vent Exhaust Stack releases do not qualify as elevated releases per RG 1.145; therefore, they-were executed-by PAVAN as -"ground" type releases-requiring an assumption of a 10 m release height. The Station Chimney was executed as an elevated release with a height of 94.6 m. The Reactor Building height of 43.1 in and the minimum calculated Reactor Building vertical cross-sectional area of 1545 m were assumed for all three scenarios.

For the Station Chimney to EAB scenario, terrain effects were not considered in Rev. 0 of this calculation; however, in response to the NRC RAI dated July 22, 2005, additional PAVAN model runs were completed to incorporate the terrain data shown below in Table 3-2 for EAB X/Q. This terrain height data was obtained from the topographic map shown in Attachment L and includes the 100 fIt bluff located 1300 m in the North through East sectors, the only significant terrain feature historically considered for the Station in the Dresden UFSAR.

The format of PAVAN meteorological input consists of a joint wind direction (based on sixteen 22.5 degree sectors), wind speed (7 intervals), and stability class (7 classes) occurrence frequency distribution.

Each such meteorological joint frequency distribution for input to PAVAN was prepared from the two meteorological databases identified in Section 2.2.2, Table 2-1, by using the WGI pre-qualified program ARCONtoPAVANMETrevl (Program Number NU-840) to transform the data to a joint wind-stability occurrence frequency distribution. The seven wind speed categories were defined according to RG 1.23 (Reference 6) with the first category identified as "calm". The minimum wind speed (i.e. wind threshold) was set to 0.93 mph and calm wind speeds were assigned a value of 0.5 mph. A midpoint was also assumed between each of the RG 1.23 wind speed categories, Nos. 2-6, as to be inclusive of all monitored wind speeds. The RG 1.23 wind speed categories have, therefore, been refined in Table 3-3 as follows:
