ATTACHMENT 4 C311-94-2021 Changes to the Process Control Program and  !

the Offsite Dose Calculation Manual During 1993

1. There were no changes made to the Process Control Program documents during 1993.  !

2. The Off-Site Dose Calculation Manual (ODCM) was modified four (4) times during 1993.

Revision 3 of the ODCM was issued on January 28, 1993. Revision 3 of the ODCM changed to increase the allowable release concentration for H-3 (Tritium) from the Waste Evaporator Condensate Storage Tank from 10% of the Maximum Permissible Concentration (MPC) to 20% of the MPC. This change was necessitated by the increased concentration of Tritium in the TMI-1 Reactor Coolant that resulted from the longer operating cycle (18 months as compared to the previous approximately 12 month operating cycle).

Revision 4 of the ODCM was issued on June 15, 1993. ODCM, Rev. 4 changed Radiological Environmental Monitoring Program ' requirements in Part I, Section 8 to be consistent with Draft 8 of NUREG 0472, Rev. 3, changed the required frequency of effluent reports from semi-annual to annual consistent with TMI-1 License Amendment 173 and made some minor typographical error corrections.

Revision 5 of the ODCM was issued on July 21, 1993. Revision 5 of the ODCM added certain operating and shutdown requirements related to PWD-RML-1, a radiation monitor for the TMI-2 Processed Water Disposal System, to the ODCM consistent with TMI-2 Recovery Operations Plan Change Request 47. The ,

changes related to PWD-RML-1 did not impact any portion of the ODCM related 1 to TMI-1. In addition, Revision 5 changed the approver of the ODCM from the Director, Nuclear Assurance to Rad con Director, TMI in accordance with Revision 10 of 1000-ADM-1291.01, Nuclear Safety Review and Approval Procedure for TMI-1 and Oyster Creek.

On August 2,1993 Revision 6 of the ODCM was issued. Revision 6 changed the configuration of two (2) TMI-2 radiation monitors, HP-R-219 and HP-R-219A to delete the requirement to monitor for radiciodine from TMI-2 exhaust pathways. Revision 6 to the ODCM did not impact any portion of the ODCM related to TMI-1. J

3. There were no new locations for dose calculations and/or environmental monitoring identified by the land use census pursuant to Part 1, Section 8.2 of the ODCM.

INTERPRETATION OF DOSE

SUMMARY

TABLE 1 Dose Summary Table 1 presents the maximum hypothetical doses to an individualand the general population resulting from the release of gaseous and liquid effluents from TMI-1 during the first half reporting period of 1993.

A. Liouid (IndividuaD  !

The first two lines present the maximum hypothetical dose to an individual. Presented are the whole body and critical organ doses.

Calculations are performed on the four age groups and eight organs recommended in Regulatory Guide 1.109. The pathways considered for ,

TMI are the consumption of drinking water and fish and standing on the i shoreline influenced by TMI effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna Riverin the vicinity of TMI. The " receptor" would be that individual who consumes water from the Susquehanna River and fish i residing in the plant discharge, while occupying an area of shoreline influenced by the plant discharge.

After calculating the doses to all age groups for all eight organs resulting l from the three pathways described above, Dose Summary Table 1 l presents the maximum whole body dose and affected age group along with the organ and associated age group that received the largest dose.

For the first half of 1993 the calculated maximum whole body dose would  ;

have been 7.36E-2 mrem to an adult.Similarly,the maximum organ dose would have been 1.01E-1 mrem to the liver of a teen.

B. Gaseous (Individual)

There are six major pathways considered in the dose calculations for gaseous efnuents. These are: (1) plume exposure, (2) inhalation, consumption of; (3) cow milk,(4) vegetables and fruits, (5) meat, and (6) standingon contaminated ground. Real-timemeteorology was usedin all dose calculations for gaseous effluents.

1 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. Dose Summary Table 1 presents the distance in meters to the location in the l affected sector (compass point) where the theoretical maximum plume l exposures occurred. The calculated maximum plume exposures would l have been 2.63E0 mrad and 2.85E0 mrad for gamma and beta, respectively.

I

l l

Lines 5 and 6 present the doses which could actually be received by an individualfrom the noble gas effluents for the first half of 1993. The calculated maximum whole body dose received by anyone from noble gases would have been 1.74E-1 mrem and the maximum dose to the skin would have been 3.53E-1 mrem.

l Line 7 represents the maximum exposed organ due to iodine, particulates and tritium. The dose presented in this section again reflects the .

I j maximum exposed organ for the appropriate age group.

l l The iodines, particulates and tritium released in the first half of 1993 would have resulted in a maximum dose of 7.30E-2 mrem to the thyroid of an infant residing 580 meters from the site in the WNW sector. No I other organ of any age group would have received a greater dose.

1 C. Liouid and Gaseous (Ponulation) 1 l Lines 8 - 11 present the person-rem doses resulting from the liquid and l gaseous efiluents. These doses are summed over all pathways and the  :

l affected populations. The person-rem doses from liquid efiluents are based upon the population encompassed within the region from the TMI l outfall extending down to the Chesapeake Bay. The person-rem doses from gaseous effluents are based upon the 1980 population and consider the population out to a distance of 50 miles around TML Population doses are summed over all distances and sectors to give an aggregate dose.

Based upon the calculations performed for the first half of 1993, liquid effluents resulted in a whole body population dose of 1.11E0 person-rem.

The maximum critical organ population dose from liquid efIluents was i 1.18E0 person-rem to the thyroid. Gaseous effluents resulted in a whole l l body population dose of 4.17E-1 person-rem and a maximum critical l

organ population dose of 8.18E-1 person-rem to the skin. i l

SUMMARY

TABLE 2 Dose Summary Table 2 presents the maximum hypothetical doses to an individualand the ,

, general population resulting from the release of gaseous and liquid effluents from TMI-1 l during the second half reporting period of 1993.  ;

i A. Liouid (IndividuaD The first two lines present the maximum hypothetical dose to an individual.

Presented are the whole body and critical organ doses. Calculations are l performed on the four age groups and eight organs recommended in i Regulatory Guide 1.109. The pathways considered for TMI are the '

consumption of drinking water and fish and standing on the shoreline i influenced by TMI effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The " receptor" would be that individualwho consumes water from the Susquehanna River and fish residingin thL plant discharge, while occupying an area of shoreline influenced by the plant discharge.

After calculating the doses to all age groups for all eight organs resulting from the three pathways described above, Dose Summary Table 2 presents the maximum whole body dose and affected age group along with the organ and associated age group that received the largest dose.

For the second half of 1993 the calculated maximum whole body dose would have been 7.88E-1 mrem to an adult. Similarly,the maximum organ dose i would have been 1.09E0 mrem to the liver of a teen. l B. Gaseous (IndividuaD l There are six major pathways considered in the dose calculations for gaseous effluents. These are: (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 i calculations for gaseous effluents.

Lines 3 and 4 present the maximum plume exposure at or beyond the site l 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. Dose Summary Table 2 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 2.47E0 mrad and 2.49E0 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 efnuents for the second half of 1993. The calculated maximum whole body dose received by anyone from noble gases would have been 1.57E-1 mrem and the maximum dose to the skin would have been 3.16E-1 mrem.

)

Line 7 represents the maximum exposed organ due to iodines, particulates and tritium. The dose presented in this section again reflects the maximum exposed organ for the appropriate age group.

The iodines, particulates and tritium released in the second half of 1993 would have resulted in a maximum dose of 2.88E-1 mrem to the thyroid of an infant residing 580 meters from the site in the WNW sector. No other organ of any age group would have received a greater dose.

C. Liauid and Gaseous (Ponulation)

Lines 8 - 11 present the person-rem doses resulting from the liquid and gaseous effluents. These doses are summed over all pathways and the affected populations. The person-rem doses from liquid effluents are based upon the population encompassed within the region from the TMI outfall extending down to the ChesapeakeBay. The person-rem doses from gaseous effluents are based upon the 1980 population and consider the population out to a distance of 50 miles around TMI. Population doses are summed over all distances and sectors to give an aggregate dose.

i

Based upon the calculations performed for the second half of 1993, liquid effluents resulted in a whole body population dose of 3.15E0 person-rem.

The maximum critical organ population dose from liquid effluents was 1.90E1 person-rem to the thyroid. Gaseous effluents resulted in a whole body population dose of 5.48E-1 person-rem and a maximum critical organ population dose of 2.63E0 person-rem to the thyroid.

INTERPRETATION OF DOSE

SUMMARY

TABLE 3 Dose Summary Table 3 presents the total maximum hypothetical doses to an individual and the general population resulting from the release of gaseous and liquid effluents from TMI-1 during 1993.

1 Liouid (Individual)

The first two lines present the maximum hypothetical dose to an individual.

Presented are the whole body and critical organ doses. Calculations are performed on the four age groups and eight organs recommended in Regulatory Guide 1.109. The pathways considered for TMI are the consumption of drinking water and fish and standing on the shoreline influenced by TMI effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TML The " receptor" would be that individ.alwho consumes water from the Susquehanna River and fish residingin the plant discharge, while occupying an area of shoreline influenced by the plant discharge.

After calculating the doses to all age groups for all eight organs resulting from the three pathways described above, Dose Summary Table 3 presents the maximum whole body dose and affected age group along with the organ and associated age group that received the largest dose.

For 1993 the calculated maximum whole body dose would have been 8.62E-1 mrem to an adult. Similarly, the maximum organ dose would have been 1.19E0 mrem to the liver of a teen.

B. Gaseous (Individual)

There are six major pathways consideredin the dose calculations for gaseous effluents. These are: (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. Dose Summary Table 3 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 5.10E0 mrad and 5.34E0 mrad for gamma and beta, respectively.  !

Lines 5 and 6 present the doses which could actually be received by an individualfrom the noble gas effluents for 1993. The calculated maximum whole body dose received by anyone from noble gases would have been j 3.31E-1 mrem and the maximum dose to the skin would have been 6.69E-1 l mrem.

Line 7 represents the maximum exposed organ due to iodines, particulates l and tritium. The dose presented in this section again reflects the maximum l exposed organ for the appropriate age group.

1 The iodines, particulates and tritium released in 1993 would have resulted in a maximum dose of 3.61E-1 mrem to the thyroid of an infant residing 580 meters from the site in the WNW sector. No other organ of any age group would have received a greater dose.

C. Liauid and Gaseous (Pon@,n)

Lines 8 - 11 present the s n-rem doses resulting from the liquid and gaseous effluents. These doses are summed over all pathways and the affected populations. The person-rem doses from liquid effluents are based upon the population encompassed within the region from the TMI outfall extending down to the ChesapeakeBay. '"he person-rem doses from gaseous effluents are based upon the 1980 popul . ,nd consider the populationout ,

to a distance of 50 miles around TMI.1 mtion doses are summed over all distances and sectors to give an aggregate dose.

Based upon the calculations performed for 1993, liquid effluents resulted in a whole body population dose of 4.26E0 person-rem. The maximum critical organ population dose from liquid effluents was 2.02E1 person-rem to the thyroid. Gaseous effluents resulted in a whole body population dose of 9.66E-1 person-rem and a maximum < N alorgan population dose of 3.36E0 person-rem to the thyroid.

Assessment of Radiation Doses From Liquid and Gaseous Effluents Releases to Members of the Public Within The TMI-l Site Boundaries During 1993 l The Offsite Dose Calculation Manual requires an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of public due to their activities inside the site boundary (figure 5.3, TMI-l Technical Specifications) during the reporting period. The public did not have unrestricted access to the TMI-l site during 1993. Therefore no assessment of this dose is applicable.

ATTACHMENT 9 i C311-94-2021 Assessment of Radiation Dose to Most Likely Exposed Real Individual Per 40 CFR 190 The Offsite Dose Calculation Manual (0DCM) Part 3, Section 2.10 requires an annual assessment of radiation dose to the most likely exposed real individual from reactor releases and other nearby uranium fuel cycle sources (TMI Unit 2) to demonstrate compliance with 40 CFR 190 " Environmental Radiation Protection Standards for Nuclear Power Operations." The annual dose to the maximum exposed individual (regardless of age group) from gaseous and liquid effluents released from TMI-1 and TMI-2 in 1993 w>uld be no greater than 0.87 mrem to the thyroid 2

and 1.64 mrem to any other organ including the whole body. The direct radiation component was determined using the highest 1993 fenceline exposure rate as measured by a TLD. Based on the maximum exposure rate of 6.9 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 0.63 mR. combining the direct l

radiation exposure (assumed to equal to dose) with the maximum organ doses from liquid and gaseous releases, the maximum potential (total) dose would have been 1.50 mrem to the thyroid and 2.27 mrem to any other organ. Both doses are well below the limits specified in 40 CFR 190.

2 The data for the TMI-2 portion of the combined Station dose is a best estimate utilizing the available station data. Analyses of a liquid sump sample and an isotopic characterization of the alpha radiation in an air particulate sample were not completed at the time of this report. The calculation of the radiation dose to the most likely exposed real individual will be updated when the analyses results are available. It is believed that the combined Station dose will not significantly change when the missing data is incorporated into the current calculation.
