Introduction The purpose of the meteorological program being conducted at the Braidwood Station U 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 320 ft. high and is instrumented at two levels. Wind speed and direction are measured at 34 ft. and 203 ft. Ambient temperature is measured at 30 ft. Differential temperature, referenced to 30 ft., is measured at 199 ft. Dew point temperature is measured at 30 ft. Precipitation is measured at approximately 3 ft.I.Joint frequency stability wind rose tables of wind direction, wind speed, and stability are routinely tabulated from hourlyvm.e.surements.T.be.quadrtedy.andcannualtables-are included in this report.Descriptions of the instruments and data loggers 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.

Murray & Trettel, Inc. 600 First Bank Drive, Suite A Palatine, Illinois 60067 (847) 963-9000 3. Data Acquisition Wind speed and direction are measured with MR[ model 1022 wind sensors. The wind[3 speed sensors have a starting speed of 0.5 mph (0.22 mps), a range of 0 to 100 mph (0 to 44.7 mps), and a system accuracy of +/-1.25 mph at 100 mph (+/-0.56 mps at Li 44.7 mps). The wind direction sensors have a threshold speed of 0.75 mph (0.33 mps), a range of 0 to 5400, and a system accuracy of +/-50.Ambient and differential temperature are measured with MRI model 1596602 sensors.Ambient temperature is measured within the range of -22 to 122 0 F (-30 to 50 0 C) with an accuracy of +/-0.5 0 F (+/-0.3 0 C). Differential temperature is measured within the range of-10 to 10OF (-5.6 to 5.6 0 C) with an accuracy of +/-0.18 0 F (+/-O.10°C).

Dew point temperature is measured with an MRI model 1993900000 dew point sensor and the range of measurement is -2t-T-22-F

(-30 to 50°C) with an accuracy of +/-2.7 0 F (+/-1.5 0 C).Precipitation is measured with a Climatronics 100097-1 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).

Instrument types and locations are summarized in Table 1.The meteorological data are collected and stored by a Microtel 4.0 data acquisition system. The Microtel measures the analog voltages of the instruments and records the digital equivalent within the range of 0 to +5 volts. The Microtel has the capability of storing 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 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.0 As a backup to the Microtel, data are also recorded with a Johnson Yokogawa Corp. digital recorder (JYC DA1 00 data acquisition unit and Contec IPC-PT/M300(PC)WOU PC). Data are sampled every 10 seconds.0 Data loggers are summarized in Table 2.Murray & Tretcel, Inc. 600 First Bank Drive, Suite A Palatine, Illinois 60067 (847) 963-9000 Table 1 Instrument Locations Measurement Wind Speed Wind Direction Differential Temperature Wind Speed Wind Direction Ambient Temperature Dew Point Temperature Precipitation Sensor Tye MRI 1022-S MRI 1022-D MRI 1596602 MRI 1022-S MRI 1022-D MRI 1596602 MRI 1993900000 Climatronics 100097-1 Location Tower Tower Tower Tower Tower Tower Tower Ground Elevation 203 ft.203 ft.199 ft.34ft.34ft.30 ft.30 ft.3 ft.a Table 2 Data Logpers Sampling Measurement Loaaer Type Frequency Winds, Temperatures, Microtel 4.0 data acquisition system I sec.and Precipitation Winds, Temperatures, Johnson Yokogawa Corp.

Data Analysis The Braidwood 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 Roto1-Mean-Square_(RIMS)_oLUefour-quarter-our-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 digital recorder 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.

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.Murray & Trettel, Inc. 600 First Bank Drive, Suite A Palatine, llinois 60067 (847) 963.9000 A professional meteorologist reviews the data, calibration findings, equipment nmaintenance 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 Microtel 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. Wind direction, wind i speed. anstability-classes-are-giv.enin..Iables_3,-4-and-5.

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 NRC 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, DIQ values.Output from the XOQDOQ program is used as input to the GASPAR program.2. GASPAR II: A Code System for Evaluation of Radiological Impacts Due to the Release of Radioactive Material to the Atmosphere During Normal Operation of Light Water Reactors (NUREG-0597).

GASPAR is a program written for the evaluation of radiological impacts due to the release of radioactive material to the atmosphere during normal operation of reactors.

The GASPAR code implements the radiological impact models of NRC Regulatory Guide 1.109, Revision 1, for atmospheric releases.

The program is used to estimate the maximum individual doses at In selected locations in the vicinity of the plant.Murray & Trettel, Inc. 600 First Bank Drive, Suite A Palatine, Mlinois 60067 (847) 963.9000 5. Results 5.1 Instrument Maintenance The maintenance program followed during 2012 was composed of routinely scheduled visits and non-routine 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 four months. A description of the calibration and field procedures is found in the Murray and Trettel, Inc. "P1009 Procedures Manual" (July 2010).In March, the 34 ft. wind direction sensor was replaced due to high readings.In April, process computer points were checked for accuracy after replacement of the plant process computer.In May, the annual tower inspection was performed.

In July, the 203 ft. wind direction sensor and the 203 ft. wind speed cups were replaced due to damage.In October, the digital recorder was unreachable by modem. The unit was rebooted to restore communication.

In November, the Microtel was not responding via modem. The unit was rebooted and the RAM was cleared to restore operation.

Also in November, the 34 ft. wind direction sensor was replaced due to sensor failure.In December, the 203 ft. wind direction sensor was replaced due to low readings.No other significant problems were encountered with the equipment, and at the end of the year, no problems were evident at the site.Murray & Trettel, Inc. 600 First Bank Drive, Suite A Palatine, Illinois 60067 (847) 963-9000 5.2 Data Recovery The record of data recovery for the year is summarized in Table 6.Table 6 Braidwood Data Recovery Summary 2012 Measurement Wind Speed Wind Speed Wind Direction Wind Direction Ambient Temperature Differential Temperature Dew Point Temperature Precipitation Elevation 34 ft.203 ft.34 ft.203 ft.30 ft.199-30 ft.30 ft.3 ft.Recovered Hours 8745 8744 8718 8712 8744 8745 8745 8752 Recovered.
