SITE: LIMERICK GENERATING STATION - UNITS 1 & 2 LICENSEE: EXELON GENERATION COMPANY, LLC B. Maximum Permissible Concentrations:
Gaseous dose rates rather than effluent concentrations are used to calculate permissible release rates for gaseous releases. The maximum permissible dose rates for gaseous releases are defined in ODCM Controls 3.2.2.2.a and 3.2.2.2.b.
The Maximum Permissible Concentrations (MPC) specified in 10 CFR 20, Appendix B, Table II, Column 2 (pre 1994) for identified nuclides, were used to calculate permissible release rates and concentrations for liquid release per the Limerick Offsite Dose Calculation Manual Control 3.2.1.1. The total activity concentration for all dissolved or entrained gases was limited to
< 2E-04 4Ci/ml.
C. Average Energy (E:
The Limerick ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin. Therefore, the average beta and gamma energies (E) of the radionuclide mixture in releases of fission and activation gases as described in Regulatory Guide 1.21, "Measuring, Evaluation, 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 to Limerick.
D. Measurements and Approximations of Total Radioactivity:
- 1. Fission and Activation Gases The method used for Gamma Isotopic Analysis is the Canberra Gamma Spectroscopy System with a gas Marinelli beaker. Airborne effluent gaseous activity was continuously monitored and recorded in accordance with ODCM Table 4.2-2. Additional vent grab samples are taken from the North Stack, Unit 1 South Stack and Unit 2 South Stack and analyzed at least monthly to determine the isotopic mixture of noble gas activity released for the month. The data from the noble gas radiation monitor was analyzed to report net noble gas effluent activity. When no activity was found in the grab isotopic analysis, the isotopic mixture was assumed to be that evaluated in the UFSAR (Section 11.5, Table 11.5-4). If activity was found in the grab isotopic analysis, the isotopic mixture for the Noble Gas Monitor was determined from that isotopic mixture. When no isotopic activity was identified in the grab noble gas samples, the noble gas radiation monitor 15-minute average data for one-hour prior to and one-hour post noble gas grab sampling were used to determine monitor background for the month. The mean plus two standard deviations was used as background for each Noble Gas Monitor. When activity was identified the background determination was made from the last month that no activity was found.
- 2. Particulates and lodines The method used is the Canberra Gamma Spectroscopy System with a particulate filter (47 mm) or charcoal cartridge, respectively. Particulate and iodine activity was continuously sampled and analyzed in accordance with ODCM Table 4.2-2. Charcoal and particulate samples are taken from the North Stack, Unit 1 South Stack, Unit 2 South Stack and the Hot Maintenance Shop exhausts and analyzed at least weekly to determine the total activity released from the plant based on the highest vent flow rates recorded for the sampling period.

- 3. Liquid Effluents Each batch of liquid effluent was sampled and analyzed for gamma isotopic activity in accordance with ODCM Table 4.2-1 prior to release. The total activity of each released batch was determined by multiplying each nuclide's concentration by the total volume discharged and then summing. The total activity released during a month was then determined by summing the activity content of all batch releases discharged during the month.
- 4. Tritium in Liquid and Gaseous Effluents:
Tritium in Liquid Effluents is analyzed using a Liquid Scintillation Counter.
Air from stack effluents was passed through two bubblers in series and an aliquot of the water from each bubbler was analyzed using a Liquid Scintillation Counter.
- 5. Composite Samoles and Lower Limit of Detection (LLD)
Particulate air samples were composited quarterly and analyzed for gross alpha, Sr-89 and Sr-90. Liquid radwaste samples were composited monthly and quarterly and analyzed for gross alpha (monthly) and Fe-55, Sr-89 and Sr-90 (quarterly). These composites submitted to an offsite vendor laboratory for analysis. The ODCM required lower limit of detection for airborne and liquid releases are as follows:
Airborne: LLD Gross Alpha 1E-11 uCi/cc Sr-89, Sr-90 1E-11 uCi/cc 1-131 1E-12 uCi/cc 1-133 1E-10 uCi/cc Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, 1-131, Cs-134, 1E-11 uCi/cc Cs-137,Ce-141, Ce-144)
Noble Gas (Kr-87, Kr-88, Xe-1 33, Xe-1 33m, 1E-04 uCi/cc Xe-135, Xe-135m, Xe-138)
Principal Gamma Emitters (Mn-54, Fe-59, Co-58, Co-60, Zn-65, Cs-134, Cs-137, Ce-141, 5E-07 uCi/ml Ce-1 44) 1-131 1E-06 uCi/mI Entrained Gases (Kr-87, Kr-88, Xe-1 33, 1E-05 uCi/mI Xe-133m, Xe-135, Xe-1 35m, Xe-1 38)

SITE: LIMERICK GENERATING STATION - UNITS 1 & 2 LICENSEE: EXELON GENERATION COMPANY, LLC Per ODCM Control 6.2, the Annual Radioactive Effluent Release Report shall include an assessment of the radiation doses to the hypothetically highest exposed MEMBER OF THE PUBLIC from reactor releases and other nearby uranium fuel cycle sources. For purposes of this calculation the following assumptions were made:
Gaseous
" Annual average meteorology and actual gaseous effluent releases were used.
- Beta air dose attributed to noble gas releases.
- The sector with the highest x/Q, x/Q depleted and D/Q was the SE sector at Site Boundary 762 meters.
- All significant pathways were assumed to be present
- Occupancy factor was considered 100%.
Liquid
- Average river flow rate for the year (2.4035E+03 cfs) was used.
A summary of gaseous and liquid radiation doses to members of the public at these locations was as follows:
Effluent Applicable Estimated Age Location % of Limit Unit Organ Dose Group Distance Direction Applicable (meters) (toward) Limit Noble Gas Gamma - Air Dose 2.19E-03 All 762 SE 1.1OE-02 20 mRad Noble Gas Beta - Air Dose 1.38E-03 All 762 SE 3.45E-03 40 mRad Noble Gas Total Body (Gamma) 1.45E-03 All 762 SE 1.45E-02 10 mrem Noble Gas Skin (Beta) 2.71 E-03 All 762 SE 9.03E-03 30 mrem

Water 3.60E-02 6 mrem Liquid Liver 2.32E-03 Teen LGS Outfall 1.16E-02 20 mrem Doses calculated were well below all ODCM and 40 CFR Part 190 limits of 25 mrem to a real individual.
ODCM Control 6.2 also requires that 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 MEMBER 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. Areas within the site boundary, where radiation dose of this type could occur include the Limerick Information Center on Longview Road near the rear exit of the plant, Frick's Lock on the west shore of the Schuylkill River and the railroad tracks that runs along the east shore of the River. The dose to State Police and National Guard personnel around the location of the Security Checkpoint was 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:
- Annual average meteorology and actual effluent releases were used.
- Beta air dose attributed to noble gas releases.
- Dose is from ground plane and inhalation only. No ingestion dose.
- Adult age group was used for the State Police and National Guard Dose.
" The x/Q, x/Q depleted and D/Q for the highest exposed sector for the railroad tracks (W), and the sectors enclosing Security Checkpoint, Frick's Lock and the Information Center available for occupancy were used.
- The maximum expected occupancy factor is 25% of a working year in all locations.
Page 27
SITE: LIMERICK GENERATING STATION - UNITS 1 & 2 LICENSEE: EXELON GENERATION COMPANY, LLC
- Distance to the railroad tracks, which pass through the Site Boundary in the W sector, is approximately 225 meters.
" Distance to the Limerick Information Center is approximately 884 meters in the ESE sector.
- Distance to Frick's Lock is approximately 450 meters in the WSW sector.
- Distance to Security Checkpoint is approximately 682 meters in the NNE sector.
A summary of gaseous radiation doses to members of the public at these locations is as follows:
Approx. GAMMA Beta Air Iodine/Part/H3 Distance AIR Dose, Organ Dose, DOSE,1 Location Sector (meters) MRAD( ) MRAD(2) MREM(3)

(2) The limit for Beta Air Dose = 40 mRad/Yr (ref. ODCM 3.2.2.2.b)
(3) The limit for Iodine/Particulate/H-3 Organ Dose = 30 mrem/Yr (ref. ODCM 3.2.2.3.b)
