Revised Dresden Nuclear Power Station 2002 Radioactive Effluent Release Report

Reference:

Letter from R.J. Hovey (Exelon Generation Company, LLC) to U. S. NRC, wDresden Nuclear Power Station 2002 Radioactive Effluent Release Report and Offsite Dose Calculation Manual Changes," dated April 30, 2003 The referenced letter submitted, in part, the Radioactive Effluent Release Report for January through December 2002 for Dresden Nuclear Power Station (DNPS) in accordance with Sections 6.9.A.4 and 5.6.3, "Radioactive Effluent Release Report," of the DNPS Unit 1 and Units 2 and 3 Technical Specifications, respectively and 10 CFR 50.36a(a)(2),

"Technical specifications on effluents from nuclear power reactors."

As a result of a self-assessment of the effluent monitoring program, an error was discovered in the report for the total activity reported for unmonitored liquid releases. The value for total activity was incorrectly summed. This error does not affect the calculated dose to the public and is administrative in nature. The report was completely reviewed and no other errors were found. This submittal corrects that value and resubmits the report.

Should you have any questions concerning this letter, please contact Mr. Jeff Hansen, Regulatory Assurance Manager, at (815) 416-2800.

1) Less than 1500 mrem/year, Dose

1) 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. For Liquid

1) 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 10.1 and 10.2 from the Offsite Dose Calculation Manual.

d. For liquid effluents, allowable release limits are calculated by solving equations 10.3 and 10.4 from the Offsite Dose Calculation Manual.

3. Average Energy The average energy of fission and activation gases was calculated for the gaseous effluents released from the site.

The average energy is based on the percentage of each fission gas nuclide present and its average energy per disintegration (E in MeV/dis) for gamma and beta emissions separately.

EaAMMA 6.39E-01 MeV/dis EBETA = 4.37E-01 MeV/dis I

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 Unit I Chemical Cleaning Building effluents are continually sampled for iodines and particulates. These samples are pulled weekly and analyzed by gamma isotopic. The particulate filters are composited and sent to a vendor for gross alpha, Sr-89/90 and Fe-55 analysis. Noble gas grab samples are pulled and analyzed by gamma isotopic weekly. Tritium samples are pulled and analyzed monthly.

For the Units 2/3 Chimney and Units 2/3 Reactor Building Vent effluents, the average flow at the release points is used to calculate the Curies released. For the Unit 1 Chimney and Unit 1 Chemical Cleaning Building effluents, the design basis flows are used to calculate Curies released.

d. Liquid Effluents:

The river discharge tanks are analyzed by isotopic 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, H-3, Fe-55, Sr-89/90 content.

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

e. 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.

f. Equipment out-of-service None.

g. Estimation of Data/Corrections:

(1) On May 13, 2002, an isotopic analysis of a weekly iodine sample pulled from the Unit 1 Chemical Cleaning Building release point identified several radionuclides that are not typical for this sample location. The condition was identified on June 12, 2002 (Reference Dresden Station Condition Report #112461). Reanalysis of the sample at that time confirmed normal results without the additional radionuclides, however, due to the time period between the sampling and the re-count, the required lower-limit-of-detection (LLD) for lodine-133 could not be demonstrated for the re-count. Iodine-133 is not normally found in the Unit I Chemical Cleaning Building effluents, and as such is estimated as zero for the May 6, 2002 to May 13, 2002 sampling period.

(2) On August 7, 2002, the weekly iodine and particulates samples pulled from the Unit I Chimney release point were not analyzed for isotopic activity. The condition was identified on August 19, 2002 (Reference Dresden Station Condition Report #119830). The samples were subsequently analyzed, however, due to the time period between the sampling and the analysis, the required lower-limit-of-detection (LLD) for Iodine-133 could not be demonstrated. Iodine-1 33 is not normally found in the Unit I Chimney effluents, and as such is estimated as zero for the July 31, 2002 to August 7, 2002 sampling period.

1. Number of Releases:

2. Total Activity Releases: 4 ?7pR-n4 ri A.1 In June, 1994, elevated tritium levels were discovered in the on-site storm sewers. The highest storm drain concentration measured during 2002, 87 pCi/l , was used for all of 2002. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute. An estimated 1.73E-03 Ci of H-3 may have been released into the environment.

Various storm sewer locations on-site are periodically analyzed for Tritium.

A.2. From January 1, 2002 through April 30,2002, a leak was present in the Units 2/3 Cribhouse from Heating Steam system piping. The Heating Steam system at Dresden has historically been contaminated with small amounts of radioactivity.

Based upon bounding assumptions, it is estimated that a total of 2.53E-04 Ci was discharged to the environment A.3 Grab samples of the Service Water effluent are routinely collected and analyzed for radioactivity. Gamma spectroscopy analysis identified Mn-54 on one of the samples taken in 2002. A total of 1.63E-03 Ci is estimated to have been released during the period for which this sample was applicable.

A.4 Grab samples of the Wastewater Treatment System effluent are routinely collected and analyzed for radioactivity. Gamma spectroscopy analysis identified Co-60 and/or Mn-54 on several samples taken in 2002. A total of 2.52E-04 Ci is estimated to have been released via this pathway.

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

Revision 01 - August, 2003 DRESDEN NUCLEAR POWER STATION UNITS 1, 2 AND 3 RADIOACTIVE EFFLUENT RELEASE REPORT January Through December 2002 DOCKET NUMBER: 50-010/50-237/50-249 UNMONITORED RELEASES* (Continued)

B. 1 The Unit I Main Turbine Floor (MTF) is used as an area to work on contaminated equipment. The ventilation, which exhausts through the Unit 1 Main Chimney, 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 3.6E-05 Ci per year of Cs-137.

B.2 The Chemistry Hotlab ventilation exhausts directly into the environment without any monitoring. The calculated release to the environment is 2.911E-04 Ci of noble gases and 8.64E-06 Ci of iodines/particulates.

B.3 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. A total activity of 7.23E-06 Ci is estimated to have been released to the environment from this system during 2002.

B.4 Past radiological surveys have identified low-level contamination in the East Turbine Building Ventilation ductwork. This system vents directly to the environment, therefore, a postulated release is calculated. A total activity of 3.36E-05 Ci is estimated to have been released to the environment from this system during 2002.

B.5 A functional test of the Unit 3 Isolation Condenser was conducted on January 17, 2002. In the past, low-level contamination has been introduced into the shell side of the condenser/heat exchanger, which vents directly to the environment. As a result, actuation of this system prompts sampling and isotopic analysis of the shell side contents. For this event, a total activity of 5.1 5E-05 Ci is estimated to have been released to the environment.

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