Braidwood Station Action ItemsPendina Action Items Problem Recommended Solution Raw-none-date Exelon was notified of problem or date of Monthly Report where problem was first reported2. Equipment Maintenance at Braidwood A regular scheduled visit to inspect the equipment was made on the 140 of March. TheRoutine Site Visitation Log, a record of existing onsite conditions, was completed during thevisiL A copy of this log is included in this reportOn the 14th, a calibration of the meteorological tower was performed.

A copy of the log isincluded in this report.On the 28h, 2 wind direction sensors were repaired, calibrated and given new bearings.

On the 29', the 34 ft. wind direction sensor was replaced due to high readings.

No other problems were encountered with the equipment during March, and at the end ofthe month, no problems were evident at the site.Murray & Trettel, Inc. 600 Rat Bank Dq, SuitkA Paladag linois 60067 (847) 963-9000 3.

The Microtel was routinely interrogated to obtain hourly average data of wind speed,wind direction, ambient temperature, differential temperature, and dew pointtemperature.

Wind sigma (standard deviation of wind direction) and precipitation datawere also obtained.

Missing Microtel values were replaced with recorder data, whenavailable.

A professional meteorologist then reviewed the data, calibration

findings, maintenance

reports, computerized quality control checks, and other information anddetermined which data were valid. Only valid data were retained in the data base.6. ComDuter Processina Computer programs were run to generate summary tables of the hourly averages ofthe meteorological data as well as other statistics based on the monthly data record.A table of means and extremes of the measurements recorded during the month isincluded in this report. Wind direction shears (variance of wind direction betweenlevels) are also included in the table. Relative humidity was calculated using ambientand dew point temperature measurements.

7. Annual Report Preparation Joint frequency stability wind rose tables of hourly data are generated quarterly and willbe included in the annual report. These tables indicate the prevailing wind direction, wind speed, and stability classes measured during the period of observation as well asthe joint frequencies of occurrence of the wind direction, wind speed, and stability classes.Murray & Trettel, Inc. 600 Fm B=k Drve, Site A Palaan, lne ,is 60067 (847)963.9000 Braidwood Generating Station March2012Niss ValidMean Max Min Hrs HrsParameter 3Re54.3 84.6 21.040.7 63.9 8.161.4 100.0 26.79.3 29.2 Calm15.6 42.8 3.0-0.5 5.6 -2.3-1.2 36.0 -111. 03 7413 7413 74134Ft W203Ft -W33741741199Ft -.ýy203 -34 FT Dire3 74111 73334Ft Sigma Theta (deg)203Ft Sigma Theta (deg)3 FT Precipitation INMonthly Total ....Max 24 Hour TotalMax 1 Hour Total .16.3 48.0 6.010.2 49.0 1.0437407411 7431.310.310.18There were 744 hours0.00861 days <br />0.207 hours <br />0.00123 weeks <br />2.83092e-4 months <br /> in MarchTable prepared on 5/ 1/2012 at 10:25 Braidwood StationDifferential Temperature Distribution (degC/100m) 3/2012199-30 ft-7.5-7.0-6.5-6.0-5.5-5.0-4.5-4.0-3.5-3.0-2.5-2.0-1.5-1.0-0.50.00.51.01.52.02.53.03.54.04.55.05.56.06.57.07.5GEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEGEDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTDTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLTLT-7.5-7.0-6.5-6.0 *o-5.5-5.0--4.5-4.0-3.5-3.0-2.5-2.0-1.5-1.0-0.5Q.00.51.01.52.02.53.03.54.04.55.05.56.06.57.07.5000000000003090117185138802532151034432201000NRC Stability ClassesUnstableNeutralStableTOTAL NO.
