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. Where "0.00E+00" is used, it denotes that no activity was found for analyzed nuclides. All non-natural nuclides reported on the gamma isotopic reports are listed in the tables. Only the non-gamma nuclides listed in the ODCM were analyzed and are reported in the tables. 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. 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. The reported Noble Gas activities for gaseous releases are 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 2001 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.

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.

RW-C-100 was superceded by RW-AA-100 Rev.2 in order to be common with the other Exelon Nuclear facilities. The purpose of the Process Control Program (PCP) is as follows:

" Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements.

" Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the in-plant waste process systems on-site OR by on-site vendor supplied waste processing systems, meet the acceptance criteria to a licensed burial facility, as required by 10CFR Part 20, 10CFR Part 61, 10CFR Part 71, 49CFR Parts 171-172, Technical Position on Waste Form (Revision 1) [1/91], Low Level Waste Licensing Branch Technical Position on Radioactive Waste Classification [5/83], and the Station Technical Specifications, as applicable.

"* Provide reasonable assurance that waste placed in on-site storage meets the requirements as addressed within the Safety Analysis Reports for the low level radwaste storage facilities for dry and/or processed wet waste.

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 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 Frick's Lock and the Information Center available for occupancy.
4. The maximum expected occupancy factor is 25% 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.

A summary of gaseous radiation doses to members of the public at these locations is included in this Attachment.

The method used for Gamma Isotopic Analysis is the Canberra Genie System with a gas Marinelli beaker. Noble gas releases are continuously monitored with the data stored on a computer system. 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.

E. EVENTS

1. Traces of Tritium found in Holding Pond In the third quarter of 2001 a quarterly routine survey-for tritium in the Spray Pond, Cooling Towers and Holding Pond was initiated. The procedure requires meeting an LLD of 1E-5 uCi/ml. This LLD is the same as that used for effluent releases via radwaste discharge and RHR/RHR Service water continuous release analyses. The actual LLD achieved was 1.5E-6 uCi/ml. All of the third quarter samples were less than LLD. The fourth quarter samples were analyzed to an LLD of 3.24E-7 uCi/ml. A trace of tritium activity was found in the Holding Pond. The sample was recounted and the Holding Pond was resampled and reanalyzed. The activity of the samples ranged from 2.36E-7 to 5.88E-7 uCi/ml. These activities are in the range of tritium found in the environment and less than the required LLD used to analyze environmental samples. ODCM Control Section 3.4 requires an Environmental LLD of 2E-6 uCi/ml for REMP sampling.

Assuming that an activity of 5.88E-7 uCi/ml was released from the Holding Pond all year, a total activity of 0.2 Ci was released. This activity is insignificant when compared to the tritium released during 2001 via radwaste discharges of 41.9 Ci.

2. Unit 2 CST Steam Heating Coil Break Results in Potential Contamination of Auxiliary Boiler On October 30, 2001 Plant Heating Steam was placed in service to the Unit 2 CST heating coil. This followed replacement of the heating coil discharge steam trap, which had been identified as the root cause for historical heating coil water hammer. After heating steam was applied, water hammer was again observed and an investigation was started to determine why the new steam trap was not preventing the water hammer. It was found that the actual heating coil inside the Unit 2 CST had developed a leak and at heating steam pressures lower than CST head pressure, cold CST water would enter the heating coil and cause water hammer when mixed with steam. The leak was identified as being a nominal ; gpm and was being returned to the Aux Boilers through the normal Plant Heating Steam condensate return system. It is believed that the leak in the heating coil started when heating steam was initially placed in service, since no leakage was identified during system maintenance late in Spring 2001. The system was isolated throughout the summer up to the time when heating steam was placed back in service.

When the leak was discovered the heating coil was isolated to prevent any additional contamination of the Heating Steam and Aux Steam systems. It is estimated that the leak was actively getting into the heating steam return lines for about 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to isolation. This is based on when heating steam was applied, which is assumed to be when the coil leak developed, and the period of time when ambient temperature was warm enough to allow heating steam pressure to drop below CST head pressure. This equates to about 700 gallons of CST water being sent to the Plant Heating Steam and Aux Steam System.

Since the actual CST heating coil could not be repaired until a Unit shutdown, a clearance was placed on the heating coil inlet and outlet valves to maintain the coil isolated. The clearance did provide the ability to apply steam to the coil, and to drain directly to the CST dike in the event of extremely cold weather, which could lower CST temperature below the alarm limit. Plant heating steam pressure, which is regulated based on ambient temperature, was adjusted such that at its minimum pressure, the pressure would remain above the head pressure of the CST.

A sample of the return line to the auxiliary boilers was counted on the gamma spectrometer. Mn-54 (2.74E-8 uCi/ml) and Co-60 (3.33E-8 uCi/ml) were detected. No gamma activity was detected in the auxiliary boilers. The CST also had tritium activity (approximately 6E-3 uCi/ml). It is estimated that 700 gallons returned to the auxiliary boilers. The contaminants were eventually discharged to the Holding Pond via boiler blow downs and leaks and then released to the river. The activity released and associated doses are insignificant when compared to the amount released during 2001 from liquid radwaste discharges. Some tritium was also released due to steam leaks in the boiler system. For 2001, the amount of tritium released via the stacks was 36.8 Ci. The activity of tritium released and associated doses from this event are insignificant when compared to the amount released via the stacks.

'I February 12, 2002 Mr. Ed Frick Limerick Generating Station P.O. Box 2300, MS SSB2-1 Evergreen and Sanatoga Roads Pottstown, PA 19464 RE: Transmittal of LGS 2001 Dispersion Values and Joint Frequency Distributions

Dear Ed:

Enclosed you will find the annual X/Q and D/Q values and the joint frequency distributions of wind speed, wind direction and atmospheric stability class for your use in preparing the LIS year 2001 effluent report. As per our recent email exchange, these are the identical receptors and pathways submitted for the 2000 report.

Dispersion Calculations - The annual X/Q and D/Q values were computed using a program developed at MES called LGSAPENI. This program utilizes the dispersion methodologies of Regulatory Guide 1.111, and was designed to utilize the same assumptions and calculation techniques as the LGS RMMS system. The model, therefore, computes annual X/Q and DIQ values as an accumulation of hourly X/Q's, rather than inputting the meteorological data from a joint frequency distribution. The results are presented for the receptors pertinent to your needs in the following set of tables. The full computer outputs from these runs are included as Attachment 1.

Table 1 - This table contains X/Q, depleted X/Q and D/Q values from the combined North Vent at the site boundary in each sector, the onsite receptors along the railroad right-of way, the Information Center and Fricks Lock. The combined vent was modeled with a nominal flow rate of 363,000 cfm. The depleted X/Q values are also decayed with an 8.05 day half life.

Table 2 - This table contains X/Q, depleted X/Q and DIQ values from the Unit 1 and Unit 2 South Vents at the site boundary in each sector, the onsite receptors along the rail road right-of-way, the Information Center and Fricks Lock. The values are valid for either the Unit 1 or Unit 2 vent, and are based upon a nominal flow rate of 144,000 cfm. The depleted X/Q values are also decayed with an 8.05 day half life.

The combined vent was modeled with a nominal flow rate of 363,000 cfm. The depleted X/Q values are also decayed with an 8.05 day half life.

Table 4 - This table contains X/Q, depleted X/Q and D/Q values from the Unit 1 and Unit 2 South Vents for the plume inhalation pathway receptors. The values are valid for either the Unit 1 or Unit 2 vent, and are based upon a nominal flow rate of 144,000 cfm.

The depleted X/Q values are also decayed with an 8.05 day half life.

Table 5 - This table contains D/Q values from the combined North Vent for the ingestion path way receptors. These include the vegetation, meat, cow and goat pathways. The combined vent was modeled with a nominal flow rate of 363,000 cfm.

Table 6 - This table contains D/Q values from the Unit 1 and Unit 2 South Vents for the inges tion pathway receptors. These included the vegetation, meat, cow and goat pathways.

The values are valid for either the Unit 1 or Unit 2 vent, and are based upon a nominal flow rate of 144,000 cfm.

Joint Frequency Distributions - Annual joint frequency distributions of wind speed, wind direction and atmospheric stability class are presented in Attachment 2. These distributions are computed for the 30-ft and 175-ft levels of Meteorological Tower No. 1, but utilize the allowable substitutions for missing data from the equivalent levels of Meteorological Tower No. 2, as specified in Table I 3.1-1 of the LGS ODCM. The joint frequency distributions are identified as Wind Level 1, which is the Tower 1 30-ft level, allowing substitution of data from the Tower 2 159-ft level, and Wind Level 2, which is the Tower 1 175-ft level, allowing substitution of data from the Tower 2 304-ft level. Atmospheric stability class in both distributions is based upon the Tower 1 266-26 ft delta temperature, with substitution for missing data from the Tower 2 300-26 ft delta temperature, again as specified in Table I 3.1-1.

Because the ODCM allows the Tower 2 substitutions, the annual joint data recovery rates at each level are excellent, with a 99.91% annual recovery rate at both Wind Level 1 (30-ft), and Wind Level 2 (175-ft). These recovery rates are well in excess of the NRC 90% joint data recovery requirement.

These distributions are based upon all available hours at each level, and are not a function of stability class.

1. PURPOSE 1.1. The purpose of the Process Control Program (PCP) is to:

1.1.1. Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements. (CM-I) 1.1.2. Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the in-plant waste process systems on-site OR by on-site vendor supplied waste processing systems, meet the acceptance criteria to a Licensed Burial Facility, as required by 10CFR Part 20, 10CFR Part 61, 10CFR Part 71, 49CFR Parts 171-172, "Technical Position on Waste Form (Revision 1)" [1/91],

"Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification" [5/83], and the Station Technical Specifications, as applicable.

1.1.3. Provide reasonable assurance that waste placed in "on-site storage" meets the requirements as addressed within the Safety Analysis Reports for the low level radwaste storage facilities for dry and/or processed wet waste.

2. TERMS AND DEFINITIONS 2.1. Process Control Program (PCP): The program which contains the current formulas, sampling, analysis, tests, and determinations to be made to ensure that processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in 10CFR Parts 20, 61 and 71, state regulations, and burial site requirements.

2.2. Solidification

Liquid waste processed to either an unstable or stable form per I OCFR61 requirements. Waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas, samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability (e.g. High Integrity Container).

2.3. Stabilization

Liquid waste processed to a "stable state" per 10CFR61 Requirements.

Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification "stabilization" criteria. This processing method is currently not available, because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples, tests, etc.

RW-AA-100 Revision 2 Page 2 of 10 2.4. Solidification Media: An approved media (e.g. Barnwell - vinyl ester styrene, cement, bitumen) when waste containing greater than 5-year half lives is solidified in a container when the activity is greater than 1 micro curie/cc. Waste solidified in a HIC is approved by the commission meeting the 10CFR61 stabilization criteria, including 1% free standing liquids by volume when the waste is packaged to a "stable" form and < 0.5%

when waste is packaged to an "unstable" form. The formulas, sampling, analysis, and test do not require NRC approval, because the HIC meets the stability criteria.

2.4.1. Solidification to an unstable or stable state are performed by vendors, when applicable.

Liquid waste solidified to meet stabilization criteria (10CFR61 and 01-91 Branch Technical Requirements) must have documentation available that shows that the process is approved by the NRC or disposal facility.

2.5. Dewatering

The removal of liquids from liquid waste streams to produce a waste form that meets the requirements of 10CFR Part 61 and applicable burial site criteria, <0.5%

by volume when the waste is packaged to an "unstable" state, or_<1 % by volume when the waste is packaged to a "stable"form.

2.6. Hiqh Integrity Container (HIC): A disposable container that is approved to the container's Certificate of Compliance 10CFR Part 61 Requirements for meeting stability. The use of HIC's is an alternative to solidification or encapsulation in a steel container to meet burial stability. HIC's are used to package dewatered liquid wastes, (e.g. filter cartridges, filter media, resin, sludges, etc), or dry active waste.

2.7. Encapsulation

The process of placing a component (e.g. cartridge filters or mechanical components) into a special purpose disposable container and then completely surrounding the waste material with an approved stabilization media, such as cement.

2.8. Liquid Waste Processing Systems: In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, solidification, or reverse osmosis (RO) for the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs).

2.9. Incineration, RVR, and/or Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where by the volume reduced by thermal means meets 10CFR61 requirements.

2.10. Compaction: When dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor.

2.11. Waste Streams: Consist of but are not limited to

- Filter media (powdered, bead resin and fiber),

- Filter cartridges,

- Pre-coat body feed material,

- Contaminated charcoal,

- Fuel pool activated hardware,

- Fuel Pool Crud

RW-AA-1 00 Revision 2 Page 3 of 10

- Sump and tank sludges,

- High activity filter cartridges,

- Concentrated liquids,

- Contaminated waste oil,

- Dried sewage or wastewater plant waste,

- Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities.

Other radioactive waste generated from cleanup of inadvertent contamination.
