It was the result of a steam line leak in the Unit 1 Intermediate Building. The steam leak released 9.05E-2 curies of tritium into the environment. The resultant dose from this event was 2.89E-4 mrem. This source term was included in the annual dose calculations for 2004.

2004 Annual Radioactive Effluent Releases Report for TMI 5928-05-20101 Changes to the Process Control Program and the Offsite Dose Calculation Manual during 2004, And a listing of new locations for dose calculations and/or environmental monitoring Identified by the land use census

1. Changes to the Process Control Program There were no changes to the Process Control Program.

2. Changes to the Offsite Dose Calculation Manual There were no changes to the Offsite Dose Calculation Manual.

3. A listing of new locations for dose calculations and/or environmental monitoring identified by the Land Use Census.

Based on the results of the 2004 Land Use Census, no changes to the Radiological Environmental Monitoring Program or the dose model are required.

2004 Annual Radioactive Effluent Releases Report for TMI 5928-05-20101 Instrumentation not Returned to Operable Status within 30 Days During 2004 There was no instrumentation not returned to operable status within 30 days per the TMI ODCM Part 1, Sections 2.1.1.b and 2.1.2.b and Part 2, Section 2.1.2.b during 2004.

2004 Annual Radioactive Effluent Releases Report for TMI 5928-04-20101 Annual Summary of Hourly Meteorological Data for 2004 During the spring calibration of the TMI meteorological tower the presence of two osprey were observed nesting on top of the tower. Since the osprey are a protected species, TMI with the agreement of the U.S. Nuclear Regulatory Commission, and input from the USDA Wildlife Service and the Pennsylvania Game Commission agreed to postpone the calibration of the meteorological tower until after the osprey left their nest. The completion of the spring calibration was performed in the fall of 2004. The-2004 meteorological data recovery was 96 percent. TMI has rescheduled the performance of the semi-annual calibrations to occur before and after the osprey nest on the tower. A detailed description of this event and the subsequent actions are documented in the TMI Corrective Action Program, Issue Report # 216604.

2004 Annual Radioactive Effluent Releases Report for TMI 5928-04-20101 Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from TMI during 2004 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2004 TMI-1 releases of gaseous and liquid effluents.

Provided below is a brief explanation of the table.

A.

Liquid (Individual)

Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-1 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-1 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-1 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-1 liquid discharge.

For 2004, the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 1.12E-2 mrem to an adult (line 1). The maximum organ dose was 1.41 E-2 mrem to the liver of an adult (line 2).

B.

Gaseous (Individual)

There were six major pathways considered in the dose calculations for TMI-I gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.

Lines 3 and 4 present the maximum plume exposure at or beyond the site boundary. The notation of "air dose" is interpreted to mean that these doses

I I

are not to an individual, but are considered to be the maximum doses that would have occurred at or beyond the site boundary. The table presents the distance in meters to the location in the affected sector (compass point) where the theoretical maximum plume exposures occurred. The calculated maximum plume exposures were 9.61 E-5 mrad and 1.95E-4 mrad for gamma and beta, respectively.

The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 2004 was 1.58E-2 mrem to the liver, total body, thyroid, kidney, lung and GI-LLI of an child residing 2150 meters from the site in the NNE sector (line 5). This dose again reflects the maximum exposed organs for the appropriate age group.

For 2004, TMI-1 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

I TMI-2 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2004 TMI-2 releases of gaseous and liquid effluents.

Provided below is a brief explanation of the table.

A.

Liquid (Individual)

Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-2 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-2 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor I was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-2 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-2 liquid discharge.

For 2004, the calculated maximum whole body (or total body) dose from TMI-2 liquid effluents was 6.28E-4 mrem to an adult (line 1). The maximum organ dose was 9.98E-4 mrem to the liver of a teen (line 2).

B.

Gaseous (Individual)

There were six major pathways considered in the dose calculations for TMI-2 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.

Since there were no noble gases released from TMI-2 during 2004, the gamma and beta air doses (lines 3 and 4, respectively) were zero.

The maximum organ dose due to the release of particulates and tritium from TMI-2 in 2004 was 2.98E-5 mrem to the liver, total body, thyroid, kidney, lung and GI tract of a child residing 2000 meters from the site in the SE sector (line 5).

For 2004, TMI-2 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

2004 Annual Radioactive Effluent Releases Report for TMI 5928-05-20101 Assessment of Radiation Doses from Liquid and Gaseous Effluents Releases to Members of the Public within the TMI Site Boundaries during 2004 The Offsite Dose Calculation Manual requires an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of the public due to their activities inside the site boundary during the reporting period. The estimated dose to a member of the public at or within the TMI Site Boundary was 0. 5 mrem for 2004.

The following are the assumptions made in this assessment:

Access to the TMI Owner Controlled Area is limited by Site Security to only those persons who have business related activities that support the operation of the facility.

Therefore, based on the definition of a 'member of the public' in NUREG-1301, there is no credible scenario for this individual to receive non-occupational dose inside the TMI Owner Controlled Area. The scenario selected will be recreational use of the Susquehanna River and shoreline next to the Owner Controlled Area fence. Based on the two definitions of Site Boundary in the ODCM, this scenario is AT the Site Boundary for liquid releases but INSIDE the Site Boundary for gaseous releases.

A member of the public stays next to the owner controlled area for 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months . The 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months is based upon Reg. Guide 1.109 shoreline recreation period given in Table E-5.

This is a table of recommended values to be used for the maximum exposed individual in lieu of site-specific data. Three Mile Island is co-located with other islands in the Lake Frederick area of the Susquehanna River. This area is used recreationally for boating and fishing over the summer months. The application of the 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months of recreational use from Reg. Guide 1.109 is appropriate.

The dose from liquid effluents were included in this scenario. The highest activity contained in releases from TMI are from batch releases from the Waste Evaporator Condensate Tanks. The maximum time period for a single release was 11 hours1.273148e-4 days 0.00306 hours 1.818783e-5 weeks 4.1855e-6 months .

Since the time of a single release is less than the 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months of recreational use of the river, the highest quarterly cumulative dose from liquid effluents will be used in this calculation. The highest quarterly cumulative dose was 8.66E-3 mrem, total body. This cumulative dose included both batch and continuous liquid releases. Assuming that the total dose from a quarter was received in the 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months is conservative.

The highest dose from a single airborne release is characterized by release G200408551. This release contained the highest concentration of tritium of any gaseous release. In 2004, tritium released in gaseous effluents comprised 99 percent of the total curies released to the environment. No other releases would yield a higher dose than the release with the highest tritium concentration. This release occurred over 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months . The entire dose from this release will be applied to the 67 hour7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months recreational use period. The application of the total dose from this release to 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months is conservative. The total dose from release G200408551 was 1.65E-2 mrem to the critical receptor.

i r The highest fenceline TLD result will be added to the dose from the highest liquid and gaseous releases to yield the hypothetical maximum dose to a member of the public within the site boundaries.

The highest fenceline TLD result for 2004 was from Station G1-6 and was 5.1 mrem per standard month.

Calculations:

5.1 mrem/std mo.

1/30.44 d/std mo.

1/24 hr/day

67 hr = 0.47 mrem The dose from gas release G200408551 was 0.017 mrem.

The quarterly cumulative dose from liquid effluents was 0.00866 mrem.

Total Dose Calculation 0.47 mrem + 0.017 mrem + 0.009 = 0.496 mrem

2004 Annual Radioactive Effluent Releases Report for TMI 5928-05-20101 Assessment of Radiation Dose to Most Likely Exposed Real Individual per 40 CFR 190 Dose calculations were performed to demonstrate compliance with 40 CFR 190 (ODCM Part IV Section 2.10). Gaseous and liquid effluents released from TMI-1 and TMI-2 in 2004 resulted in maximum individual doses (regardless of age group) of 0.022 mrem to the thyroid and 0.031 mrem to any other organ including the whole (total) body. The direct radiation component was determined using the highest quarterly fence-line exposure rate as measured by an environmental TLD, and subtracting from it, the lowest quarterly environmental TLD exposure rate.

Based on the maximum exposure rate of 5.1 mR/standard month, a person residing at the fence-line for 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months (shoreline exposure from Reg. Guide 1.109) received an exposure of 0.47 mR. Based on the lowest exposure rate of 1.6 mR/standard month and converting it by the same method yielded a background exposure of 0.15 mR.

Therefore, the net exposure from direct radiation from TMINS was 0.32 mR. Combining the direct radiation exposure (assumed to be equal to dose) with the maximum organ doses from liquid and gaseous releases, the maximum potential (total) doses were 0.34 mrem to the thyroid and 0.35 mrem to any other organ. Both doses were well below the limits specified in 40 CFR 190.
