1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Summary of Unplanned Releases from the TMI Site During 1999 There were no unplanned releases to unrestricted areas from either the TMI-1 or TMI-2 site during 1999.

1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Changes to the Process Control Program and the Offsite Dose Calculation Manual during 1999, 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 made to Process Control Program (PCP) documents in 1999.

2. Changes to the Offsite Dose Calculation Manual during 1999 The Offsite Dose Calculation Manual (ODCM) was modified twice during 1999. These changes did not reduce the accuracy or reliability of dose calculations or setpoint determinations. The level of effluent controls required by 10 CFR 20.1301, 40 CFR 190, 10 CFR 50.36a, and Appendix I to 10 CFR 50 was not reduced and the accuracy or reliability of effluent, dose or setpoint calculations was not adversely impacted for the reasons stated below.

Revision 18 of the ODCM was issued on February 9, 1999. Revision 18 made the following changes to the ODCM:

This PCR was submitted to update ODCM Table 2.1-2 to reflect that effluent system flow rate measuring devices 2AH-FR-5064 (Containment Purge) and 2HP VIP-219 (Station Ventilation) were replaced by a multi-point recorder, 2AH-FR 5907. This change was evaluated and implemented in CCR #132607. The new recorder provides the same function as the old devices.

Revision 19 of the ODCM was issued on March 23, 1999. Revision 19 made the following changes to the ODCM:

This PCR was submitted to correct a typographical error that was introduced into Technical Specifications in 1990 and subsequently transferred into the ODCM when effluent controls were transferred from Technical Specifications to the ODCM in Technical Specification Amendment 197. Specifically, the oxygen concentration specified in the Action Statement of ODCM Control 2.2.2.5.b was changed from 2%

to 4%, as was stated in the original Technical Specification. The action statements as written were not logical, since Action b would always be the applicable action since it requires an additional action for the same concentration as specified in Action a. The PCR restored the Action Statements to the intent of the original Technical Specification.

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 1999 Three Mile Island Nuclear Station land use census, there were no locations identified that yielded a calculated dose or dose commitment greater than the values currently being calculated in ODCM Part I Surveillance 3.2.2.3.1. Additionally, there were no locations identified that yielded a calculated dose or dose commitment 20% greater than at a location from which samples are currently being obtained in accordance with ODCM Part III Table 1.

1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Instrumentation not returned to Operable status within 30 days during 1999 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 1999.

1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from TMI during 1999 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 1999 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 eight 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 1999, the calculated maximum whole body dose from TMI-1 liquid effluents was 1.56E-1 mrem to an adult (line 1). The maximum organ dose was 2.32E-1 mrem to the liver of a teen (line 2).

B. Gaseous (Individual)

There were six major pathways considered in the dose calculations for TMI-1 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 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 would have been 4.74E-3 mrad and 1.59E-2 mrad for gamma and beta, respectively.

Lines 5 and 6 present the doses which could actually be received by an individual from the noble gas effluents for 1999. The calculated maximum whole body dose received by anyone from noble gases would have been 2.14E-3 mrem and the maximum dose to the skin would have been 6.74E-3 mrem.

The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 1999 was 1.44E-2 mrem to the thyroid of an infant residing 580 meters from the site in the WNW sector (line 7). This dose again reflects the maximum exposed organ for the appropriate age group.

C. Liquid and Gaseous (Population)

Lines 8 - 11 present the person-rem doses resulting from 1999 TMI-1 liquid and gaseous effluents. These doses were summed over all pathways and the affected populations. The person-rem doses from liquid effluents were based upon the population encompassed within the region from the TMI-1 outfall extending down to the Chesapeake Bay (approximately 5,000,000 people). The person-rem doses from gaseous effluents were based upon the 1980 population and considered the population out to a distance of 50 miles around TMI (approximately 2,200,000 people). Population doses were summed over all distances and sectors to give an aggregate dose.

The calculated maximum whole body dose to the affected population from TMI-1 liquid effluents was 1.14E1 person-rem. The maximum critical organ population dose from liquid effluents was 1.1 4E1 person-rem to the liver. TMI-1 gaseous effluents resulted in a whole body population dose of 3.72E-1 person-rem and a maximum critical organ population dose of 4.25E-1 person-rem to the thyroid.

For 1999, TMI-1 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly 10 CFR 50 Appendix I dose limits.

TMI-2 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 1999 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 eight 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 1999, the calculated maximum whole body dose from TMI-2 liquid effluents was 6.13E-4 mrem to an adult (line 1). The maximum organ dose was 9.54E-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 1999, 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 1999 was 1.05E-4 mrem to the liver, total body, thyroid, kidney, lung and GI tract of a child residing 2150 meters from the site in the NNE sector (line 5).

C. Liquid and Gaseous (Population)

Lines 6 - 9 present the person-rem doses resulting from 1999 TMI-2 liquid and gaseous effluents. These doses were summed over all pathways and the affected populations. The person-rem doses from liquid effluents were based upon the population encompassed within the region from the TMI-2 outfall extending down to the Chesapeake Bay (approximately 5,000,000 people). The person-rem doses from gaseous effluents were based upon

the 1980 population and considered the population out to a distance of 50 miles around TMI (approximately 2,200,000 people). Population doses were summed over all distances and sectors to give an aggregate dose.

The calculated maximum whole body dose to the affected population from TMI-2 liquid effluents was 8.18E-4 person-rem. The maximum critical organ population dose from liquid effluents was 2.92E-3 person-rem to the bone. TMI-2 gaseous effluents resulted in a whole body population dose of 9.87E-3 person-rem and a maximum critical organ population dose of 9. 87E-3 person-rem to the liver, thyroid, kidney, lung and GI tract.

For 1999, TMI-2 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly 10 CFR 50 Appendix I dose limits.

1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Assessment of Radiation Doses from Liquid and Gaseous Effluents Releases to Members of the Public within the TMI Site Boundaries during 1999 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 public did not have unrestricted access to the TMI site during 1999. Therefore no assessment of this dose is applicable.

1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 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 1999 would have resulted in maximum individual doses (regardless of age group) of 3.04E-2 mrem to the thyroid and 2.43E-1 mrem to any other organ including the whole body. The direct radiation component was determined using the highest 1999 fenceline exposure rate as measured by a TLD and subtracting from it the lowest TLD exposure rate. This method more accurately determines the exposure from TMINS by subtracting out the exposure rate from other sources of radiation in the environment. Based on the maximum exposure rate of 9.62E0 mR/standard month, a person residing at the fenceline for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> (shoreline exposure from Reg. Guide 1.109) would have received an exposure of 8.82E-1 mR. Based on the lowest exposure rate of 3.23E0 mR/standard month and converting it by the same method gives a background exposure of 2.96E-1 mR. Therefore, the net exposure from direct radiation from TMI is 5.86E-1 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) dose would have been 6.16E-1 mrem to the thyroid and 8.29E-1 mrem to any other organ. Both doses are well below the limits specified in 40 CFR 190.

0 1999 Annual Radioactive Effluent Releases Report for TMI 5928-00-20128 Deviation from the ODCM Sampling and Analysis Regime during 1999 There were no deviations from the effluent sampling and analysis regime specified in the TMI Offsite Dose Calculation Manual during 1999.
