Introduction ABS Consulting engineers have used the ARCON961 computer code to analyze the X/Q values at the control room intake for releases at Unit 3 of the Indian Point Generating Station. Pacific Northwest National Laboratory developed ARCON96 for the United States Nuclear Regulatory Commission. The purpose of the code is to determine the X/Q values at receptors on or near buildings from releases on or near buildings for various averaging times. It includes corrections for building wakes, low wind speeds, elevated and vent releases, and area releases.

Input Data ARCON96 requires the use of hourly meteorological data for a period of at least one year. This data must include the wind direction, wind speed, and stability class; and may optionally include wind direction and wind speed for a second meteorological instrument at another height. The meteorological data used for this analysis was collected at the Indian Point Generating Station in 1995, 1996, and 19972. ABS Consulting received the data on diskettes and a program was written to extract the data to the format required by ARCON96 3 . The wind instruments at heights of 10 m and 60 m were used. Wind speed in the unconverted data has units of miles per hour for wind speed and 'F for temperature and temperature difference measurements 4 . The converted file retains the wind speed units as miles per hour, while the temperature differences are converted to stability classes A to G.

ARCON96 also requires data on the source and receptor locations, as well as other geometric data, flow data, and the initial plume dimensions. For the source, the code requires that the release be specified as a ground, vent, or stack release. If the release is well above the attached building, it is a stack release. If it is not a stack release, but is released with a large enough vertical velocity, ARCON96 treats it as a vent release. The code treats releases from the surface of the building without vertical velocity as ground releases. The model also requires the release height, building area, vertical velocity, stack flow (volumetric flow rate), and stack radius. The building area was taken to be the lateral area of the containment building. The receptor data includes the distance from the source, the direction from the source, the intake height, and the elevation difference if the source and receptor are measured from different reference planes.

ARCON96 also requires the initial plume dimensions for area releases. The determination of these values will be discussed below. There are several other input values, but they did not need to be altered from their default values for this analysis.

The ARCON96 analysis for the Indian Point Nuclear Plant required calculation of X/Q values for five locations: a containment surface leak, a release from the containment vent, the side of the auxiliary boiler feed building, the auxiliary boiler feed building safety valve organ pipes, and the auxiliary boiler feed building atmospheric dump valve silencers. Instructions on determining the locations of the release points and the control room intake were taken from Letter NEA-05-002 5 .

We took the information used to determine the location and size of the containment surface leak (described in the next paragraph) from U.E. & C. drawing 9321 -F-13 1936 and the receptor location (the point on the surface closest to the control room intake was chosen). The height of the containment vent was taken from the same drawing, and the horizontal coordinates were taken from drawing C0047. The locations of the auxiliary boiler feed building safety valve "organ pipes" were taken from drawing 9321-F-20493 8 for the horizontal coordinates and from drawing 9321-F-20503 9 for the elevation. The location of the silencers was taken from Con Ed Drawing A210148-l'o The location of the intersection of the shield wall and the containment (the closest point on the auxiliary feed pump building south wall to the control room intake) was taken from drawings C0047 and 9321-F-40433-5 11, and the dimensions of the blowout panels from Drawing 9321-F-14853' 2 . The location of the control room intake was taken from drawing 932 1-F-R-1 109298-01, Rev. 4 Page 6 of 26 2 February 2005

4017313. These values were then used to determine the distance from the source to the receptor, and with a correction from plant north to true north, for the direction to the source. The grade elevation, used to determine the height of the source and receptor locations above the ground, was taken to be the top of the paved area South and West of the containment on drawing C004 .

The ARCON96 manual states that, "Methods for determining the initial diffusion coefficients that define a virtual source involve subjective decisions." Numerical integration over the part of the surface available for release, (that is, above the adjoining buildings where present), was used to determine the effective distance and height of the containment surface release. The heights and locations of the adjoining buildings (i.e., the electrical tunnel, auxiliary feed pump building, and fan house) were taken from drawings 9321-F-15363 14 and 9321-F-40433-5 1 . The initial plume standard deviations used were equal to one-sixth of the width and available height of the containment. For the release from the side of the auxiliary boiler feed, the intersection of the containment and the shield wvall was the closest point to the control room intake, and was used for the release. The initial plume dimensions for that case were one sixth of the height and average width of the blowout panels on the south side of the building, projected onto a vertical plane perpendicular to the line of sight from the release point to the control room intake.

The auxiliary boiler feed building safety valve organ pipes were modeled using the closest point on the organ pipe that is closest to the control room intake, and was modeled as a point release. The auxiliary boiler feed building atmospheric dump valve silencers were modeled using the closest point on the silencer that is closest to the control room intake, and was modeled as a point release. The containment vent release was modeled at the center of the vent. The initial horizontal plume dimension for vent releases is the equivalent vent diameter divided by six. Table I shows the source and receptor locations, Table 2 shows the geometric input data locations, and Table 3 shows the flow and initial plume size data, and Table 4 shows miscellaneous input data.

Methodology We prepared the input data on a Microsofte Excel spreadsheet. A Visual Basice macro translated the data from the spreadsheet into input files for ARCON96, and wrote a batch file to run the cases. The batch file invoked ARCON96 to run the individual cases and produce the required output. Another Visual Basics macro read the data back into the spreadsheet. The results for the individual cases were printed and used to verify that the input and output data agreed with the values on the spreadsheet.
