DC00040-111 Revision 0 page 4 of115 1.0 PURPOSE The purpose of this analysis is to calculate values for short term accident X/Q's using the PAVAN (Reference 1) computer code. Values are determined in accordance with USNRC Regulatory Guide 1.145 (Reference 2) for the 0.5% maximum sector X/Q and the 5% direction independent value.

The term X/Q (sec/m3) is an expression of the relative dispersion occurring between a source (release) location and a receptor location. This relative dispersion can then be used to determine the expected atmospheric concentration at some defined distance away from the source for a known quantity of effluent released. The receptor locations in this analysis are defined as the VC Summer Unit 1 exclusion area boundary (EAB) and low population zone (LPZ) distances of 1 mile and 3 miles, respectively.

2.0 COMPUTER CODE WorleyParsons PAVAN-PC Computer Code, Version 0, validated 6/8/2006 based on Reference 1.

3.0 ASSUMPTIONS None requiring future verification.

1. Ground-level releases include all release points or areas that are lower than 2.5 times the height of the adjacent solids structures (NUREG/CR-2858, Section 4.4). VCS does not include a plant stack, so no release will be 2.5 times the height of the tallest structure.

2. The terrain in the vicinity of the site can be described as gently rolling hills; therefore, the default terrain adjustment factor is used for the annual average calculations.

4.0 DESIGN INPUT The design input is an integral part of the calculation and is referenced as appropriate throughout.

5.0 METHOD Attachment 1 (Reference 3) provides joint frequency distributions of hourly averages of wind speed for each of the 16 standard azimuthal sectors for the 36 month period from 7/112003 to 6/3012006. This input is entered into the PAVAN-PC code, and the X/Q values are determined both with and without credit for building wake effects.

DC00040- I I I Revision 0 page 5 of II5 The Building Area used is 1740 square meters (Reference 4). The building dimensions used to compute the minimum cross-sectional area are shown in Figure 1.

Dome EI. 602 ft.

Springline EI. 557 ft.

radius = 84.5 ft Containment Grade EI. 455 ft.

Width 134 ft.

This distance is smaller than actual distance (436 feet for grade elevation) which adds to the conservative nature of relative concentration calculations.

Figure 1 - Containment Dimensions Used for Minimum Cross-Sectional Area.

Height = 602 ft - 455 ft = 147 ft or 44.8 meters

DC00040-111 Revision 0 page 6 of 115 PA VAN Input:

The input for the PAVAN-PC code is listed as follows:

Card 1: Control Parameters KOPT(l) 0 cry and crz based on Pasquill-Gifford diffusion parameters KOPT(2) 1 X/Q values calculated with and without building wake KOPT(3) 0 do not print calculations for upper envelope curve KOPT(4) 0 do not print points used in upper envelope curves KOPT(5) 0 dummy field (not used)

KOPT(6) 0 joint frequency data input in hours KOPT(7) 0 do not print X/Q calculations KOPT(8) 1 distribute CALM array into first windspeed category KOPT(9) 0 no site specific adjustment factors for annual average calculations KOPT(lO) 1 assume default terrain adjustment factors for average annual X/Q Card 2:

A 1740 Minimum cross sectional building area (m2)

D 44.8 Height above grade of containment structure (m)

HS 10.0 Effective stack height (m), (l0.0 = ground level release default value)

TOWERH 10.0 Height above grade of wind sensors (m)

DC00040-111 Revision 0 page 7 of 115 Since KOPT(8) 1 Distribute CALM array into first wind speed category, values of zero entered.

Card 9: (Values shown in Attachment 1)

Combined joint frequency distributions (JFDs) of wind direction, wind speed (meters / second), and stability for the 10-m level for the Unit 1 tower (July 1, 2003 through June 30, 2006) are provided in Reference 3. Since the wind speed threshold value is very low (0.23 rn/s), the number of calm hours for each stability do not appear in the JFDs. PAVAN-PC distributes the calm values into the first wind speed category. The combined frequency distributions for wind speeds higher than 18 m/s are not used because the frequency is zero.

UCOR -1 Wind speed input as meters/second UMAX (Values shown in Attachment 1)

Attachment 3 DC00040-111 Revision 0 page 112 of115 Attachment 3 Alternate Values This attachment provides an alternate set of yjQ values for the EAB and LPZ using

1. the original design values provided in the VC Summer FSAR Appendix 15A, Table 15A-3 (copy attached) and currently used in the VCS Unit 1 FSAR accident dose analyses and the AST LAR,

2. the values provided by the NRC in the VC Summer SER (Nureg-0717) excerpt attached.

The values from these two documents are summarized as follows.

u. S. Nuclear Regulatory Commission Office of Nuclear Reactor Regulation February 1981

Attachment 3 DC00040-111 Revision 0 page 115 of 115 2.3.4 Short-Term Diffusion Estimates Conservative assessments of atmospheric diffusion conditions for assessing postulated accidental releases of radioactivity from buildings and vents have been based on the meteorological data collected by the applicant for the period 1975-1977 and appropriate diffusion models. In the evaluation of accidental releases from the facility buildings and vents, a ground-level release considering a building wake factor, cA, of 870 square meters was assumed. The relative concentration estimates at the exclusion area boundary and low population zone distances for the various time periods following a postulated accidental release were calculated using the diffusion models described in Regulatory Guide 1.145, "Atmospheric Dispersion Models for Potential Accident Consequence Assessments at Nuclear Power Plants," and Section 2.3.4 of the Standard Review Plan.

The relative concentration estimate for the 0-2 hour time period, which is exceeded no more than five percent of the time is estimated to be 3.3 x 10-4 seconds per cubic meter at the exclusion distance of 1.6 kilometers. This relative concentration is equivalent to dispersion conditions produced by Pasquill type F stability with a wind speed of 0.7 meter per second.

The relative concentration estimated at the low population zone distance (4.8 kilometers) for the various time periods following a postulated accidental release are:

Time period Relative concentration, seconds per cubic meter 0-8 hours 4.1 x 10.5 8-24 hours 2.6 X 10-5 1-4 days 1.0 X 10-5 4-30 days 2.6 X 10.5
