1) Less than 500 mrem/year to the whole body.

2) Less than 3000 mrem/year to the skin.

Dose Gammai Radiation (each unit)

I) Less than or equal to 5 mrad/quarter.

2) Less than or equal to 10 mrad/year.

Beta Radiation (each unit)

1) Less than or equal to 10 mrad/quarter.

2) Less than or equal to 20 mrad/year.

b.,c. Iodine-131, Iodine-133, and all radionuclides in particulate form with half-lives greater than 8 days:

Dose Rate

1) Less than 1500 mrem/year.

Dose (each unit)

I) Less than or equal to 7.5 mrem/quarter to any organ.

2) Less than or equal to 15 mrem/year to any organ.

d. Liquid effluents (each unit):

I) Less than or equal to 1.5 mrem to the whole body during any calendar quarter.

2) Less than or equal to 5 mrem to any organ during any calendar quarter.

3) Less than or equal to 3 mrem to the whole body during any calendar year.

4) Less than or equal to 10 mrem to any organ during any calendar year.

2. Maximum Permissible Concentration a., b., c. For fission and activation gases, iodines, and particulates with half-lives greater than 8 days, allowable dose rates are calculated by solving equations 2-3 and 2-4 of the Offsite Dose Calculation Manual (ODCM).

d. For liquid effluents, allowable release limits are calculated by solving equations 2-i and 2-2 of the ODCM.

3. Average Energy Average energy is not used to determine dose to the public. The ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem per year to the total body and less than or equal to 3,000 mrem per year to the skin. Compliance with these limits is demonstrated based on dose calculations using measured isotopic concentrations of effluent streams and not based on gross count rate measuring systems. Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," are not applicable.

4. Measurement and Approximations of Total Radioactivity

a. Fission and Activation Gases:

b. lodines:

c. Particulates:

The Units 2/3 and Unit I Chimneys, Units 2/3 Reactor Building Vent, and Chemical Cleaning Building effluents are continually sampled for iodines and particulates. These samples are changed weekly and analyzed by gamma spectroscopy. The particulate filters are composited and sent to a vendor for gross alpha, Sr-89, Sr-90, and Fe-55 analysis. Noble gas grab samples of the Chimneys and Vent are obtained weekly and analyzed by gamma spectroscopy. Contributing streams of the Units 2/3 Chimney and 2/3 Reactor Building Vent are also sampled and analyzed by gamma spectroscopy. Tritium samples of the Chimneys and Vent are obtained monthly and analyzed by liquid scintillation.

For the Units 2/3 Chimney and Units 2/3 Reactor Building Vent effluents, the measured flow at the release points is used to calculate the curies released. For the Unit I Chimney and Chemical Cleaning Building effluents, the design basis flows are used to calculate curies released.

d. Liquid Effluents:

The river discharge tank is analyzed for gamma-emitting nuclides by gamma spectroscopy and for tritium by liquid scintillation prior to discharge. A representative portion of this sample is saved and composited with other discharges that occur during the sampling period. The composite is sent to a vendor for analyses of gross. alpha, Sr-89, Sr-90, and Fe-55.

The tank volumes and activities are used to calculate the diluted activity released at the discharge point from batch discharges.

e. Estimated Total Errors The estimated total errors were calculated as the square root of the sum of the squares of significant errors present in the sampling and analysis process.

f. Less than the Lower Limit of Detection (<LLD)

Samples are analyzed such that the ODCM LLD requirements are met. When a nuclide is not detected, then

<LLD is reported.

g. Estimation of Data/Corrections:.

The Units 2/3 Main Chimney particulate and iodine sampling was interrupted on July 21, 2007 from 1415 to 1800 due to personnel error (inadvertent mis-positioning of a flow control switch). The particulate and iodine activities are determined by applying the measured concentrations for the balance of the sampling period to the time period that sampling was interrupted.

c. Gaseous - None

6. Abnormal Releases*

a. Liquid I. Number of releases: 1

2. Total activity released: 1.56E+02 Ci

b. Gaseous

1. Number of releases: 2

2. Total activity released: 4.70E-03 Ci

a. I Tritium was detected in the Unit 2 Service Water system effluent during routine monthly sampling on November 12, 2007. No other nuclides were detected. For conservatism, it is assumed that the detected tritium concentration was released for the entire time between the preceding sample drawn October 15, 2007 at 1407 and the succeeding sample drawn December 17, 2007 at 0705. No activity was detected in the preceding or succeeding samples. The release volume is calculated from this time period and the estimated flow rate of the system (3.00E+04 gallons per minute). For this event, an estimated 1.56E+02 Curies of tritium was released.

b. I An unplanned actuation of the Unit 2 Isolation Condenser occurred at 23 17 on May 4, 2007, due to a reactor scram and Group I isolation. In the past, activity was detected on the shell side of the condenser / heat exchanger, which vents directly to the atmosphere. As a result, actuation of this system prompts sampling and isotopic analysis of the shell side contents and the downspouts from roofs under the exhaust. The highest concentrations of activity detected immediately before, during, and after the actuation were used for release calculations. Only tritium and Co-60 were detected. Volume of the release was based on makeup pump run times and changes in shell-side level. For this event, an estimated 1.49E-03 Ci tritium and 1.72E-05 Ci Co-60 were released to the environment as a ground-level gaseous release.

b.2 An access door on a 2/3 Chimney duct was found ajar on June 12, 2007. Investigation concluded the door was ajar for a maximum of 74 hours8.564815e-4 days 0.0206 hours 1.223545e-4 weeks 2.8157e-5 months and the maximum flow was 2000 scfm, and these maximum values were used for calculating the sample volume. Measurements of activity released from the 2/3 Chimney surrounding the event, consisting of tritium, Mn-54, Co-60, 1-131, 1-133, Xe-135, and Ba-140 were used to estimate the concentration of activity released. For this event, an estimated 3.19E-03 Ci of total activity was released to the environment as a ground-level gaseous release.

'These releases are included in the Effluents Summation of all Releases Tables and in the Radiological Impact on Man.

7. Unmonitored Releases*

a. Liquid

1. Number of releases: I

2. Total activity released: 1.44E-01 Ci

b. Gaseous

1. Number of releases: 3

2. Total activity released: 1.86E-04 Ci

a. I Water in on-site storm sewers is routinely sampled and analyzed for tritium content. The highest storm drain concentrations measured during each calendar quarter of 2007 was used to calculate the released activity for each quarter. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute. An estimated 1.44E-01 Ci of tritium was released to the environment during 2007.

b. I The Unit I Main Turbine Floor (MTF) is used as an area to work on contaminated equipment. The ventilation system is no longer operational and the floor is at ambient pressure with the outside environment. With radiological work activities being performed on the MTF, the potential exists for airborne activity to be released to the environment through various potential release points. The estimated release through these points is 3.60E-05 Ci of Cs-137 during 2007.

b.2 The Unit 2/3 Heating Steam system has low-level contamination present. During operation of the system, some steam is vented directly into the environment. It is estimated that 1.22E-06 Ci of Mn-54 and 9.91 E-07 Ci of Co-60 were released for a total estimated activity of 2.21 E-06 Ci released to the environment from this system during 2007.

b.3 The Chemistry Laboratory Ventilation system exhausts directly into the environment and is not monitored. The estimated activity released to the environment in 2007 is 1.44E-04 Ci of noble gases and 3.86E-06 Ci of iodines and particulates.

These releases are included in the Effluents Summation of all Releases Tables and in the Radiological Impact on Man.

8. Summary of Offsite Dose Calculation Manual (ODCM) Changes by Dresden Nuclear Power Station (DNPS) in 2007 Revision 6 of the ODCM was issued on June 7, 2007. The revision implements the standard Exelon format and as a result, the entire layout of the ODCM is changed. The previous version of the DNPS ODCM consisted of a several chapters that were common to all of the former CoinEd nuclear stations and then site-specific chapters; therefore most chapters had individual revision numbers. The revision is a single site-specific document. A summary of the changes made is listed in the following table:

Old Section Rev 6 Section Description of Change Throughout Throughout Changed "Radiological Effluent Technical Standards" or "RETS" to "Radioactive Effluent document document Controls" or "RECs" Throughout Throughout Changed "whole body" to "total body" and updated equation variables to be consistent with document document NUREG- 1302 Throughout Throughout Relocated sections to comply with CY-AA- 170-300 format document document RETS RECs Formatted to comply with ITS format 1.0 II. 1.0 Changed "presents a discussion of' to "contains" for clarification Removed "nuclear" as redundant Added "above background" for clarification Changed "environment" to "public" for clarification Changed "Radiological Effluent Technical Standards (RETS) of all CoinEd nuclear power stations" to "Radioactive Effluent Controls (RECs)" to match new format Page 4 of 129

C. CHANGES TO THE PROCESS CONTROL PROGRAM (PCP)

I. Revision 4 of RW-AA- 100, "Process Control Program for Radioactive Wastes" was issued on March 27, 2007. This revision did not constitute a significant change to the PCP because it implemented administrative enhancements only.

The enhancements implemented include the requirement todocument changes to the PCP in this report, the addition of references, and clarification of existing requirements for review and approval of vendor procedures.

2. Revision 5 of RW-AA- 100, "Process Control Program for Radioactive Wastes" was issued on June 12, 2007. The revision added "compression dewatering" to the list of available techniques in the definition for Liquid Waste Processing Systems and added "Oil Dry absorbent material added to a container to absorb liquids" to the list in the definition of Waste Streams. These changes do not constitute a significant change to the PCP. The revision also implemented an editorial clarification of existing requirements for review and approval of vendor procedures.

No major changes were made to the DNPS radioactive liquid, gaseous, or solid waste treatment systems in 2007.

DOCKET NUMBERS: 50-010/50-237/50-249 D. 40CFR190 Compliance The General Electric Morris Operation (GEMO) facility is physically located near Dresden Station and is considered in the evaluation of the uranium fuel cycle on members of the public in the general environment for 40CFRI90 compliance. The sum of the maximum doses from the units at Dresden Station is 8.27E+00 mrem. Per the 2007 GEMO IOCFR72.44(d)(3) report, the maximum dose that could be received from that facility is calculated to be 4.26E-01 mrem. A conservative estimate of the maximum dose to a member of the public in the general environment as a result of the uranium fuel cycle in the area surrounding Dresden Station is 8.70E+00 mrem, and the dose limits of 40CFR 190 (annual dose equivalent does not exceed 25 millirems to the whole body, 75 millirems to the thyroid, and 25 millirems to any other organ) are not approached or exceeded.

E. Equipment Out of Service The Units 2/3 Main Chimney particulate and iodine sampling and noble gas monitoring were interrupted on July 21, 2007 from 1415 to 1800. A switch controlling flow to the in-service monitoring and sampling equipment was mis-positioned due to personnel error, rendering on-line particulate and iodine sampling and noble gas monitoring inoperable. During this time, continuous particulate and iodine sampling was not performed as required by the ODCM. Compensatory noble gas sampling was not required due to the short duration. Monitoring was restored immediately upon discovery of the event. The particulate and iodine activity released during this event is determined as described in section 4.g of this report.
