I. INTRODUCTION This submittal complies with the format 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", Revision 1, June, 1974.

The following information is included as Tables to this report:

• A summary of the gaseous and liquid effluent releases for the report period. For 2002 data, where "0.00E+00" or a "Blank" is used, it denotes that no activity was found for samples analyzed per ODCM requirements. All LLD requirements listed in the ODCM were met. The estimated total errors stated in the gaseous and liquid summation of releases were the values quoted in past reports except for the volume of waste released and volume of dilution water for liquid releases. These errors are estimated from I&C calibration data. The Noble Gas Monitor data is analyzed to report noble gas effluent activities. When no activity is found in the Isotopic Analysis, the isotopic mixture is assumed to be that evaluated in the UFSAR (section 11.5, Table 11.5-4). If activity is found in the Isotopic Analysis, the isotopic mixture for the Noble Gas Monitor is determined from the Isotopic Analysis. The reported noble gas activities for gaseous releases are probably higher than actual noble gas releases due to a very high natural background of radon. The radon levels can vary by a wide margin from day to day and contribute to the majority of the noble gas monitor response.

• Composite particulate air samples and liquid radwaste composites, counted for beta emitters (e.g.

Fe-55, Sr-89, Sr-90) and gross alpha (air samples only), were submitted to an offsite vendor laboratory for analysis. Other required analyses were performed onsite. All vendor results were received and included in the report calculations.

Therefore the 2002 report is complete.

• A summary of solid waste dispositioned during the report period, to include: total activity shipped by waste type and the estimated composition of each type of waste by isotope; and the number of shipments, mode of transportation, destination, type of container, total container volume, and solidification agent.

3

• There was no contaminated oil burned in the Auxillary Boilers during 2002.

Additional Information:

• There were no changes to Radioactive Waste Treatment Systems during the report period.

• The Activities and Doses listed in this report are within the limits specified in 40CFR Part 190.

• Two of the tables from the 2001 ARERR contained typographical errors. The corrected tables are included in the "REVISION TO PREVIOUS SUBMITTAL" section.

TABLE II. E Page 1 of 2 RADIATION DOSES TO MEMBERS OF THE PUBLIC DUE TO THEIR ACTIVITIES INSIDE SITE BOUNDARY Per ODCM Control 3.6, the Annual Effluent Release Report shall include an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of the public due to activities inside the Site Boundary during the report period. ODCM Controls state that Members of the Public shall include all persons not occupationally associated with the plant. This category does not include employees of the utility or contractors. Also excluded from this category are persons who enter the site to service equipment or to make deliveries. This category does include persons who use portions of the site for recreational, occupational education, or other purposes not associated with the plant. The Limerick Information Center on Longview Road near the rear exit of the plant, Frick's Lock on the west shore of the river and the railroad tracks which run above the east shore of the Schuylkill River are all areas within the site boundary where radiation dose of this type could occur. The dose to LGS Guards, State Police and National Guard personnel around the location of the Security Checkpoint at the entrance to the parking lot is also included in this report. The radiation doses to Members of the Public have been estimated using methodology stated in the ODCM. The maximum gaseous dose to members of the public at these locations is based on the following assumptions:

1. Yearly average meteorology and actual effluent releases.

2. Beta air dose attributed to noble gas releases.

3. Highest exposed sector of the railroad tracks (W), and the sectors enclosing Security Checkpoint, Frick's Lock and the Information Center available for occupancy.

4. The maximum expected occupancy factor is 251 of a working year in all locations.

5. Distance to the railroad tracks, which pass through the Site Boundary in the W sector, is approximately 225 meters.

6. Distance to the Limerick Information Center is approximately 884 meters in the ESE sector.

7. Distance to Frick's Lock is approximately 450 meters in the WSW sector.

8. Distance to Security Checkpoint is approximately 682 meters in NNE sector.

3. Measurements and Approximations of Total Radioactivity A. Fission and Activation Gases in Gaseous Effluents:

The method used for Gamma Isotopic Analysis is the Canberra Genie System with a gas Marinelli beaker. Noble gas releases are continuously monitored by a radiation monitoring system with the data stored on a computer system (RMDS). The monitor data is analyzed to report noble gas effluent activities. When no activity is found in the Isotopic Analysis, the isotopic mixture is assumed to be that evaluated in the UFSAR (section 11.5, Table 11.5-4). If activity is found in the Isotopic Analysis, the isotopic mixture for the noble gas monitor is determined from the Isotopic Analysis.

B. Iodine in Gaseous Effluents:

The method used is the Canberra Genie System with a charcoal cartridge.

C. Particulate in Gaseous Effluents:

The method used is the Canberra Genie System with an air particulate sample, 47 mm filter.

D. Gamma Isotopic Analysis in Liquid Effluents:

The method used is the Canberra Genie System using a 1.0 liter Marinelli beaker. A Radwaste Liquid Discharge Pre-Release report is generated to ensure that the dose and activity to be released is within limits.

E. Tritium in Liquid and Gaseous Effluents:

Tritium in Liquid Effluents is analyzed using a Liquid Scintillation Counter.

Air from stack effluents is passed through two bubblers in series and an aliquot of the water from each bubbler analyzed using a Liquid Scintillation Counter.

E. UNPLANNED RELEASES

1. Traces of Tritium found in Holding Pond On two occasions during 2002, Tritium was found at very low concentration levels in the Waste Water Holding Pond. On February 15, 2002, Tritium was detected at a concentration of 8.49E-6 uCi/cc and on November 15, 2002, Tritium was again detected at a concentration of 1.14E-6 uCi/ml. The Tritium activity was discovered as part of a routine test (RT-5-104-800-0) to look for tritium in normally clean systems. Both of these events were traced to a break in the Unit 2 CST steam heating return line to the auxiliary boilers. With the break in the Unit 2 CST steam heating return line, boiler blowdowns and various vents in the steam heating system, an unplanned release of small amounts of tritium to the environment resulted. The amount of tritium released was reduced as much as possible through various station preventative and corrective actions.

Based on Holding Pond and Auxiliary Boiler analyses, the total amount of Tritium released to the environment from the two unplanned releases was 0.139 Curies. This value represents less than 0.2% of the annual amount of tritium released from other planned releases at LGS and is well below allowable limits.

The Unit 2 CST steam heating line was repaired during the 2003 Unit 2 refuel outage.

LIMERICK GENERATING STATION DIGLAPSE VERSION 1.0 LAPSE RATE WIND ROSE PROGRAM TO COMPUTE JOINT FREQUENCY DISTRIBUTIONS OF WIND DIRECTION AND SPEED BY ATMOSPHERIC STABILITY CLASS DIGLAPSE ALSO COMPUTES THE JOINT DATA RECOVERY RATE AS REQUIRED BY REGULATORY GUIDE 1.23. FOR BOTH THE JOINT FREQUENCY DISTRIBUTION AND DATA RECOVERY CALCULATIONS BOTH THE PRIMARY AND BACKUP SENSORS SPECIFIED IN TABLE I3.1-1 OF THE LGS OFFSITE DOSE CALCULATION MANUAL ARE USED.

THE PRIMARY AND BACK UP SENSORS USED IN THE ATTACHED DISTRIBUTIONS ARE AS FOLLOWS:

PARAMETER TOWER 1 TOWER 2 (PRIMARY) (BACKUP)

WIND SPEED LEVEL 1 30 FT. OR 159 FT.

LEVEL 2 175 FT. OR 304 FT.

WIND DIRECTION LEVEL 1 30 FT. OR 159 FT.

LEVEL 2 175 FT. OR 304 FT.

DELTA TEMPERATURE LEVELS 1 & 2 266-26 FT. OR 300-26 FT.
