1. Introduction The purpose of the meteorological program being conducted at the Ginna Plant site is to provide information sufficient to assess the local weather conditions and to determine the degree of atmospheric dispersion of airborne radioactive effluent from the station.

The meteorological tower is 300 ft. high and is instrumented at three levels. Wind speed and direction, and ambient temperature are measured at 33 ft., 150 ft., and 250 ft.

Differential temperatures, referenced to 33 ft., are measured at 150 ft. and 250 ft.

Precipitation is measured at ground level.

Joint frequency stability wind rose tables of wind direction, wind speed, and stability are routinely tabulated from hourly measurements. The annual tables are included in this report.

Descriptions of the instruments and data computers are given in Section 3 (Data Acquisition) of this report. Data reducti.on and processing are described in Section 4 (Data Analysis). The results given in Section 5 of this report include X/Q and D/Q data results and site meteorology.

2. Summary The Ginna Plant meteorological monitoring program produced 96,171 hours0.00198 days <br />0.0475 hours <br />2.827381e-4 weeks <br />6.50655e-5 months <br /> of valid data out of a possible 96,360 priority parameter hours during 2016, which represents an overall data recovery rate of 99.8%. Priority parameters are all parameters except precipitation.

The stability wind rose tables included in this report have been generated using the 33 ft.

wind data with the 150-33 ft. differential temperature data, the 150 ft. wind data with the 150-33 ft differential temperature data and the 250 ft. wind data with the 250-33 ft.

differential temperature data.

3. Data Acquisition Wind speed and direction are measured with Climatronics F460 wind sensors. The wind speed sensors have a starting speed of 0. 5 mph (0.22 mps), a range of O to 100 mph (0 to 44. 7 mps), and a system accuracy of +/-1.0 mph at 100 mph (+/-0.45 mps at 44.7 mps). The wind direction sensors have a threshold speed of 0.5 mph (0.22 mps), a range of Oto 540°, and a system accuracy of +/-5°.

Ambient and differential temperature are measured with the Climatronics 100093 system. Ambient temperature is measured within the range of -20 to 120°F (-28.9 to 48.9°C) with an accuracy of +/-0.5°F

(+/-0.3°C). Differential temperature is measured within the range of -10 to 20°F (-5.6 to 11.1 °C) with an accuracy of +/-0.18°F (+/-0.10°C). Precipitation is measured with a Climatronics tipping bucket rain gauge and is measured in increments of one one-hundredth of an inch with a system accuracy of +/-0.01"

(+/-0.25mm).

The meteorological data are collected and stored by Campbell Scientific CR3000 and CR850 data loggers. The data loggers measure the analog voltages of the instruments and record the digital

  • equivalent within the range of O to +5 volts. Data are obtained from the Campbell Scientific CR850 by a direct dial telephone hookup to an in-house computer system.

4. Data Analysis The meteorological data are collected via modem connection to a Campbell Scientific CR850 data logger. Data are sampled once per second. The data are then stored in the meteorological data base and hourly listings of the data are generated. The data listings are examined by qualified personnel and any apparent problems are brought to the attention of the Project Manager or Environmental Meteorologist and the Instrument Maintenance staff.

Hourly values of wind speed, wind direction, ambient temperature, differential temperature, and precipitation are obtained through measurements taken at the site.

The standard deviation of wind direction (sigma) is derived. The wind direction variation is described in terms of the standard deviation of the direction about the mean direction.

The MIDAS computer derives an hourly value of wind sigma.

The data base files are edited approximately once a week. Missing values are replace'd with back up data values, when available. Invalid data are deleted from the data base.

When an hourly value is missing or invalid, the numeral 999 is entered into the computer data file in the appropriate location.

A professional meteorologist reviews the data, calibration findings, equipment maintenance reports, and other information and determines which data are valid. Only the valid data are retained in the data base.

Joint frequency stability wind rose tables of hourly data measured at the site are generated. These tables indicate the prevailing wind direction, wind speed, and stability classes measured during the period of observation as well as the joint frequencies of occurrence of the wind direction, wind speed, and stability classes. The values are also used as input to the atmospheric transport and diffusion models. Wind direction, wind speed, and stability classes are given in Tables 3, 4, and 5.

5. Results 5.1 X/Q and D/Q The ground and mixed mode values for X/Q and D/Q can be found in tables 4-9.

The following program was used to calculate X/Q and D/Q values:

1. XOQDOQ: Computer Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations (NUREG/CR-2919).

The program is based on the theory that material released to the atmosphere will be normally distributed (Gaussian) about the plume centerline. A straight-line trajectory is assumed between the point of release and all receptors.

The program implements the assumptions outlined in Section C of NRG Regulatory Guide 1.111. In evaluating routine releases from nuclear power plants, it primarily is designed to calculate annual relative effluent concentrations, X/Q values and annual average relative deposition, D/Q values.

15 5.2 Instrument Maintenance In March, A calibration of the Primary Tower was performed. At the Backup Tower, the logger is reading an incorrect time and date. No data has been collected because of this issue. Site IT is aware of the issue and has yet to fix it. This issue continued through the entire year of 2017.

In April-May, the Backup Towers logger issued continued until May 12 once it was fixed.

In August, a calibration of the Primary Tower and Backup Tower was performed.

In November, a calibration of the Primary Tower and Backup Tower was performed.

No other problems were encountered with the equipment, and at the end of the year, other than the Backup Tower issues, no other problems*were evident at the site.

17 5.4 Stability Wind Rose Data The annual stability wind roses are given at the end of this report. Wind speed classes have been altered to reflect the sensor threshold.

For the year, winds measured at 33 ft. most frequently came from the southwest (13.59%) and most frequently fell into the 2.1-3.0 mis wind speed class (23.76%).

Calms (wind speeds at or below the sensor threshold) were measured 0.00% of the time and speeds greater than 10.0 mis were measured (2.04%) of the time. Winds measured at 150 ft. most frequently came from the southwest (11.26%) and most frequently fell into the 6.1-8.0 mis wind speed class (19.36%). Calms were measured 0.00% of the time and speeds greater than 10.0 mis were measured (10.24%) of the time. Winds measured at 250 ft. most frequently came from the west-southwest (11.69%) and most frequently fell into the 6.1-8.1 mis wind speed class (23.18%).

Calms were measured 0.00% of the time and speeds greater than 10.0 mis were measured (15.98%) of the time.

Stability based on the 150-33 ft. differential temperature most frequently fell into the neutral classification (33.28%) and stability based on the 250-33 ft. differential temperature most frequently fell into the neutral classification (46.03%).
