Introduction The purpose of the meteorological program being conducted at the lion Station 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 250 ft. high and is instrumented at two levels. Wind speed and direction are measured at 35 ft. and 250 ft. Ambient temperature is measured at 35 ft. Differential temperature, referenced to 35 ft., is measured at 250 ft. Dew point temperature is measured approximately ten feet from the tower at an elevation of 5 ft. Precipitation is measured by a rain gauge located on the roof of the meteorological shelter building. Joint frequency stability wind rose tables of wind direction, wind speed, and stability are routinely tabulated from hourly measurements. The quarterly and annual tables are included in this report. Descriptions of the instruments and recorders are given in Section 3 (Data Acquisition) of this report. Data reduction and processing are described in Section 4 (Data Analysis). The results given in Section 5 of this report include modeled maximum whole body doses, skin doses, organ doses based upon airborne releases, and site meteorology.

2 Summary The Zion Station meteorological monitoring program produced 52,410 hours of valid data out of a possible 52,560 parameter hours during 2010 (365 days x 24 hours/day x 6 measured priority parameters). which represents an overall data recovery rate of 99.7%. Priority parameters are all parameters except dew point temperature and precipitation. The stability wind rose tables included in this report have been generated using the 35 ft. wind data with the 250-35 ft. differential temperature data. The maximum annual calculated cumulative doses resulting from airborne releases were as follows.

Data Acquisition Wind speed is measured with Teledyne Geotech modellS64 sensors and wind direction is measured with Teledyne Geotech model 1565 sensors. The wind speed sensors have a starting speed of 0.S3 mph (0.28 mps), a range of 0 to 100 mph (0 to 44.7 mps), and a system accuracy of ~1%. The wind direction sensors have a threshold speed of 0.7 mph (0.31 mps), a range of 0 to 540°, and a system accuracy of :!:.5°. Ambient and differential temperatures are measured with RDF model 23789-4 sensors, and dew point temperature is measured with a Foxboro modeI2781-18-CGN deweell. Ambient temperature is measured within the range of -40 to 120°F (-40 to 4B.9°C) with an accuracy of :!:.O.5°F (+O.3°C). Differential temperature is measured within the range of -10 to 30°F (-5.S to IS. 7°C) with an accuracy of =0. 18°F (1:0.10°C), and dew point temperature is measured within the range of -40 to 120°F (-40 to 4B.9°C) with an accuracy of,!.2.7°F ~2.0°C). Precipitation is measured with a Climatronics model 100097 rain gauge. Precipitation is measured in increments of one one-hundredth of an inch with a system accuracy of :to.01" <:!:O.2Smm). Instrument types and locations are summarized in Table 1. The meteorological data are collected and stored by a Microtel4.0 data acquisition system. The Microtel measures the analog voltages of the instruments and records the digital equivalent within the range of 0 to +1 volt. The Micratel has the capability of storing 24 hours of minute data and one week of hourly data. Data are obtained from the Microtel by a direct dial telephone hookup to an in-house computer system, Data are sampled every second. As a backup to the Microtel, data are also recorded with a Johnson Yokogawa Corp. digital recorder (JYC DA100 data acquisition unit and Contec IPC-PT/M300(PC)WQU PC). Data are sampled every 10 seconds. Data logger information is summarized in Table 2. Murray & Trettel, Inc. 600 First Bank Driue, Suite A Palatine, lIlinois 60067 (847) 963-9000

Data Analysis The Zion Microtel is routinely interrogated to obtain hourly average data. The data are then stored in the meteorological data-base and 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 Meteorological Technician and the Instrument Maintenance staff. Hourly values of wind speed, wind direction, ambient temperature, differential temperature, dew point 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 Microtel computes an hourly value of wind sigma by taking the Root-Mean-Square (RMS) of the four quarter-hour wind sigma values. The quarter-hour wind sigma values are calculated directly from the one second wind direction samples during the 15 minute period. The data base files are edited approximately once a week. MisSing Microtel values are replaced with recorder values, when available. Invalid data are deleted from the data-base.

I I I I I I I I I I I I I I I I I I I 6 When an hourly value is missing or invalid, the numeral 999 is entered into the computer data tile in the appropriate location. When the wind direction changes substantially relative to its short term fluctuations, the numeral 888 can be entered into the wind sigma location to indicate shifting winds. When the wind blows with velocities near the sensing threshold of the instrument, the numeral 777 can be entered into the wind direction, wind speed, and wind sigma locations to indicate light and variable winds. 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. As a quality control measure, a monthly comparison is made of MicroteJ and digital recorder data. An investigation is made into the reasons for any significant differences between the sets of values. 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. W ind direction, wind speed, and stability classes are given in Tables 3, 4, and 5.

10 Results 5.1 Instrument Maintenance The maintenance program followed during 2010 was composed of routinely scheduled visits and equipment repairs. Routine site visits were made to inspect the sensing and recording systems for proper operation. In addition, routine maintenance and calibration checks of all tower-mounted and ground level equipment were performed every 4 months. A description of the calibration and field procedures is found in the Murray and Trettel, Inc. "P1009 Procedures Manua'" (July 2010). In February, the Acromag modules for the temperature system were adjusted. In March, a new Acromag was installed due to questionable readings. In April, the annual tower inspection was performed. In June, the digital recorder was unreachable by modem. The unit was rebooted. In December, there was some 250 ft. wind speed data loss due to icing. No other significant problems were encountered with the equipment, and at the end of the year, no problems were evident at the site.

Introduction The purpose of the meteorological program being conducted at the lion Station 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 250 ft. high and is instrumented at two levels. Wind speed and direction are measured at 35 ft. and 250 ft. Ambient temperature is measured at 35 ft. Differential temperature, referenced to 35 ft., is measured at 250 ft. Dew point temperature is measured approximately ten feet from the tower at an elevation of 5 ft. Precipitation is measured by a rain gauge located on the roof of the meteorological shelter building. Joint frequency stability wind rose tables of wind direction, wind speed, and stability are routinely tabulated from hourly measurements. The quarterly and annual tables are included in this report. Descriptions of the instruments and recorders are given in Section 3 (Data Acquisition) of this report. Data reduction and processing are described in Section 4 (Data Analysis). The results given in Section 5 of this report include modeled maximum whole body doses, skin doses, organ doses based upon airborne releases, and site meteorology.

2 Summary The Zion Station meteorological monitoring program produced 52,410 hours of valid data out of a possible 52,560 parameter hours during 2010 (365 days x 24 hours/day x 6 measured priority parameters). which represents an overall data recovery rate of 99.7%. Priority parameters are all parameters except dew point temperature and precipitation. The stability wind rose tables included in this report have been generated using the 35 ft. wind data with the 250-35 ft. differential temperature data. The maximum annual calculated cumulative doses resulting from airborne releases were as follows.

Data Acquisition Wind speed is measured with Teledyne Geotech modellS64 sensors and wind direction is measured with Teledyne Geotech model 1565 sensors. The wind speed sensors have a starting speed of 0.S3 mph (0.28 mps), a range of 0 to 100 mph (0 to 44.7 mps), and a system accuracy of ~1%. The wind direction sensors have a threshold speed of 0.7 mph (0.31 mps), a range of 0 to 540°, and a system accuracy of :!:.5°. Ambient and differential temperatures are measured with RDF model 23789-4 sensors, and dew point temperature is measured with a Foxboro modeI2781-18-CGN deweell. Ambient temperature is measured within the range of -40 to 120°F (-40 to 4B.9°C) with an accuracy of :!:.O.5°F (+O.3°C). Differential temperature is measured within the range of -10 to 30°F (-5.S to IS. 7°C) with an accuracy of =0. 18°F (1:0.10°C), and dew point temperature is measured within the range of -40 to 120°F (-40 to 4B.9°C) with an accuracy of,!.2.7°F ~2.0°C). Precipitation is measured with a Climatronics model 100097 rain gauge. Precipitation is measured in increments of one one-hundredth of an inch with a system accuracy of :to.01" <:!:O.2Smm). Instrument types and locations are summarized in Table 1. The meteorological data are collected and stored by a Microtel4.0 data acquisition system. The Microtel measures the analog voltages of the instruments and records the digital equivalent within the range of 0 to +1 volt. The Micratel has the capability of storing 24 hours of minute data and one week of hourly data. Data are obtained from the Microtel by a direct dial telephone hookup to an in-house computer system, Data are sampled every second. As a backup to the Microtel, data are also recorded with a Johnson Yokogawa Corp. digital recorder (JYC DA100 data acquisition unit and Contec IPC-PT/M300(PC)WQU PC). Data are sampled every 10 seconds. Data logger information is summarized in Table 2. Murray & Trettel, Inc. 600 First Bank Driue, Suite A Palatine, lIlinois 60067 (847) 963-9000

Data Analysis The Zion Microtel is routinely interrogated to obtain hourly average data. The data are then stored in the meteorological data-base and 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 Meteorological Technician and the Instrument Maintenance staff. Hourly values of wind speed, wind direction, ambient temperature, differential temperature, dew point 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 Microtel computes an hourly value of wind sigma by taking the Root-Mean-Square (RMS) of the four quarter-hour wind sigma values. The quarter-hour wind sigma values are calculated directly from the one second wind direction samples during the 15 minute period. The data base files are edited approximately once a week. MisSing Microtel values are replaced with recorder values, when available. Invalid data are deleted from the data-base. Murray & Trettel, Inc. 600 First Bank Drive, Suite A Palatine, Illinois 60067 (847) 963-9000

I I I I I I I I I I I I I I I I I I I 6 When an hourly value is missing or invalid, the numeral 999 is entered into the computer data tile in the appropriate location. When the wind direction changes substantially relative to its short term fluctuations, the numeral 888 can be entered into the wind sigma location to indicate shifting winds. When the wind blows with velocities near the sensing threshold of the instrument, the numeral 777 can be entered into the wind direction, wind speed, and wind sigma locations to indicate light and variable winds. 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. As a quality control measure, a monthly comparison is made of MicroteJ and digital recorder data. An investigation is made into the reasons for any significant differences between the sets of values. 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. W ind direction, wind speed, and stability classes are given in Tables 3, 4, and 5.

10 Results 5.1 Instrument Maintenance The maintenance program followed during 2010 was composed of routinely scheduled visits and equipment repairs. Routine site visits were made to inspect the sensing and recording systems for proper operation. In addition, routine maintenance and calibration checks of all tower-mounted and ground level equipment were performed every 4 months. A description of the calibration and field procedures is found in the Murray and Trettel, Inc. "P1009 Procedures Manua'" (July 2010). In February, the Acromag modules for the temperature system were adjusted. In March, a new Acromag was installed due to questionable readings. In April, the annual tower inspection was performed. In June, the digital recorder was unreachable by modem. The unit was rebooted. In December, there was some 250 ft. wind speed data loss due to icing. No other significant problems were encountered with the equipment, and at the end of the year, no problems were evident at the site.

Wind speed classes have been altered to reflect the wind sensor threshold. For the year, winds measured at 35 ft. most frequently came from the West (10.17%) and fell into the 3.6-7.5 mph wind speed class (42.92%). Calms (wind speeds at or below the sensor threshold) were measured 0.01 % of the time and speeds greater than 24.5 mph were measured 0.08% of the time. Stability based on the 250*35 ft. differential temperature most frequently fell into the neutral classification (35.16%).
