SUMMARY

Three Mile Island Nuclear Station Unit 1 Effluent and Offsite Dose Report for the Period of July 1,1988 to December 31, 1988 This report summarizu the radioactive liquid and gaseous releases (effluents) from Three Mile Island Unit 1 and the calculated maximum hypothetical radiation exposure to the public resulting from these releases. This report covers the period of operation from July 1 to December 31, 1988.

Radiological releases from the plant are monitored by installed plant monitors sampling the. plant stack for gaseous releases and liquid monitors for discharges to the Susquehanna River. These monitors and sample analyses provide a means for accurate determination of the type and quantities of radioactive materials being released to the environment.

Calculations of the maximum hypothetical dose to an individual and the total population around Three Mile Island due to radioactive releases from the plant are made utilizing environmental conditions that existed at the time of the release.

Susquehanna River flow data are used to calculate the maximum hypothetical doses to an individual and the population downstream of TMI due to liquid releases. Actual or "real-time" meteorological data from an onsite tower is used to determine the doses resulting from gaseous releases from tne plant. The use of real-time meteorological information permits the determination of 'voth the direction in which the release traveled and the dispersion of radioactive material in the environment.

Utilizing gaseous effluent data and real-time meteorology the maximum hypothetical dose to any individual and to the total population within 50 miles of the plant is calculated.

Similarly, Susqueharna River flow and liquid effluent data are used to calculate a maximum hypothetical dose to an individual and a population dose from liquid effluents for any shoreline exposure down to the Chesapeake Bay. Exposure to the public from consumption of water and fish withdrawn from the Susquehanna River downstream of the plant is also calculated.

Dose calculations for liquid and gaseous effluents are performed using a mathematical model which is based on the methods defined by the U. S. Nuclear Regulatory Commission.

The maximum hypothetical doses are conservative overestimates of the actual offsite doses which are likely to occur. For example, the dose does not take into consideration the removal of radioactive material from the river water by precipitation of insoluble salts, absorption onto river sediment, biological removal, or removal during processing by water companies prior to distribution i

and consumption.

1.iquid discharges made during the reporting period July 1 to December 31, 1988 consisted of 90 curies of tritium, 0.008 curies of noble gases (predominantly Xe-133), and 0.034 curies of other beta and gamma emitters, predominantly Co-58. The quantities of effluents are similar to average semi-annual releases from previous Unit 1 operations.

During~ the reporting period July 1 to December 31, 1988, the maximum hypothetical calculated whole body dose to an individual due to liquid effluents from Three-Mile Island Unit 1 was 0.06 mrem. The maximum hypothetical calculated dose to any organ of an individual was 0.09 mrem to the liver.

Airborne discharges made during this same time period consisted of 1.8 curies-of tritium, 944 curies of noble gases, and 0.00009 curies of iodines and particulate. These releases are less than average semi-annual releases from previous Unit 1 operation.

The maximum hypothetical calculated dose to any individual from noble gases-was 0.013 mrem to the skin and 0.0048 mrem to the whole body. Airborne iodine and particulate are calculated to produce 0.0037. mrem to the thyroid of the maximum hypothetical individual.

The total maximum hypothetical whole body dose of 0.067 mrem, received by any individual from effluents from TMI-1 for the reporting period is '750 times lower than the doses the average individual in the area of TMI-1 receives from natural background during the same time period. Natural background averages about 50 mrem whole body semi-annually in the TMI-1 area.

In addition, average equivalent dose to the total body from natural radon for the same period is about 100 mrem. The calculated total whole body population dose from all plant releases is 2.4 person-rem.

This is 46,000 times lower than the dose attributed to natural background radiation for the reporting period.

The doses which could be received by the maximum hypothetical individual are each less than 2% of the annual limits established by the Nuclear Regulatory Commission in Appendix I of 10 CFR 50.

INTERPRETATION OF DOSE

SUMMARY

TABLE The Dose Summary Table presents the maximum hypothetical doses to an individual and the general population resulting from the release of gaseous and liquid effluents from TMI-1 during the second half reporting period of 1988.

1 A.

Liquid (Individual) l l

The first two lines present the maximum hypothetical dose to an i ndividual. 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 drinking water, irrigated cow milk, irrigated goat milk, irrigated beef, consumption of 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 TMI. The irrigation pathways apply to the sewage sludge.

The " receptor" would be that individual who consumes water from the Susquehanna River and fish residing in the plant discharge, while occupying an area of shoreline influenced by the plant discharge and consuming the milk and beef fed irrigated vegetation.

After calculating the doses to all age groups for all eight organs resulting form the three pathways described above, the Dose Summary Table 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 1988 the calculated maximum whola body dose received by anyone would have been 0.062 mrem to an adult.

Similarly, the maximum organ dose would have been 0.086 mrem to the liver of a teenager.

B.

Gaseous (Individual)

There are seven major pathways considered in the dose calculations for gaseous effluents. These are:

(1) plume, (2) inhalation, consumption of (3) cow milk, (4) goat milk, (5) vegetables, (6) mcat, and (7) standing on contaminated ground.

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 dose that would have occurred at or beycnd the site boundary.

The Dose Summary Table presents the distance in meters to the location in the affected sector (compass point) where the theoretical maximum plume exposure occurred.

It should be noted that real-time meteorology was used in all dose calculations for gaseous effluents.

Lines 5 and 6 present the dose which could actually be received by an individual from the noble gas effluents for the second half of 1988.

The calculated maximum whole body dose received by anyone from noble gases would have been 0.0048 mrem. Similarly, the maximum dose to the skin would have been 0.013 mrem.

The iodines and particulate section described in line 7 represents the maximum exposed organ due to iodine and particulate.

This does not include any whole body plume exposure which would be separated out by lines 5 and 6.

The doses presented in this section again reflect the-maximum exposed organ for the appropriate age group.

The second half 1988 iodines and particulate would have resulted in a maximum dose of 0.0037 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.

Liquid'and Gaseous'(Population)

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.

Liquid person-rem is based upon the population encompassed.within the region from the TMI outfall extending down to the Chesapeake Bay.

The person-rem for gaseous effluents are based upon the 1980 population and consider the population out to a distanceLof 50 miles around TMI.

Population doses are summed over all distances and sectors to give an aggregate dose.

Based upon the calculations performed for the second half of 1988, liquid effluents resulted.in a whole body population dose of 2.3 person-rem.

The maximum critical organ population dose' to the thyroid was 2.6 person-rem. Gaseous effluents resulted in a whole body population dose of 0.15 person-rem. Maximum critical organ population dose to the skin was 0.51 person-rem.

February 28, 1989 C311-89-2021 US Nuclear Regulatory Commission Attn:

Document Control Desk Washington, DC 20555

Dear Sir:

Three Mile Nuclear Station Unit 1 (TMI-1)

Operating License No. DPR-50 Docket No. 50-289 Second Half - 1988 Semi Annual Effluent and Release Report Enclosed is the TMI-1 Semi Annual Effluent and Release Report for the period July 1, 1988 through December 31, 1988. This report includes an Executive Summary of the Effluent Release Report, the Disposal and Effluent Release Data, and an assessment of the radiation doses due to liquid and gaseous effluents released from the Unit during the reporting period.

TMI Technical Specification Sections 6.9.4.2.1 and 6.9.4.2.2 require reporting of effluent data and solid waste shipment data in accordance with Reg.

Guide 1.21 for the semi-annual report period. These tables are attached including summaries of solid waste shipments and liquid and gaseous effluents for the reporting period.

TMI Technical Specification Section 6.9.4.2.3 requires a summary of unplanned releases from the site to unrestricted areas. During this report period, there were no unplanned releases.

TMI Technical Specification Section 6.9.4.2.4 also requires that changes to the Process Control Program (PCP) and Offsite Dose Calculation Manual (0DCM) be reported. There were no changes to either of these programs. This section also requires "a listing of rew locations for dose calculations and/or monitoring identified by the land use census pursuant to Specification 3.23.2."

There were no new locations during this semi-annual period.

TMI Technical Specification Section 6.9.4.2.5 requires reporting of instrumentation not returned to OPERABLE status within 30 days por Section 3.21.1.b and 3.21.2.b.

All instrumentation under this Tech. Spec. section was returned to OPERABLE service within 30 days.

TMI Technical Specification Section 6.9.4.3.1 requires an annual summary of hourly meteorological data collected over the previous year. This data is contained in the attached Joint Frequency Tables.

In accorc's.:e with Technical Specification Section 6.9.4.3.2, this report includes an annual cummation table and a semi-annual table showing the assessment of the radiation doses due to liquid and gaseous effluents released from the Unit during 1988.

Technical Specification Section 6.9.4.3.3 also requires in part that annually this same report shall include "an assessment of the radiation doses from i

radioactive liquid and gaseous effluents to MEMBERS OF THE PUBLIC due to their l

activities inside the site boundary (Figures 5-3 and 5-4) during the report period." Since the public does not have unrestricted access to TMI-1, no assessment of this dose is applicable.

j TMI Technical Specification Section 6.9.4.3.4 requires an annual assessment of radiation dose to the likely most exposed real individual from reactor releases and other nearby uranium fuel cycle sources (TMI Unit 2) to show compliance with 40 CFR 190 " Environmental Radiation Protection Standards for Nuclear Power Operations." For the purpose of Technical Specification 6.9.4.2, the annual dose to the maximum exposed individual from effluents for comparison to 40 CFR 190, would be no greater than 0.2 mrem. This sums together doses from Unit 1 and Unit 2 and includes the maximum regardless of age group for different pathways.

It is further estimated based on the maximum average fenceline dose rate for the year of 26.6 mrem above background per standard month, a person residing at the fenceline for the duration specified in i

RG 1.109 for shoreline exposure, would receive no more than 2.5 mrem direct dose, for a maximum potential total dose of 2.7 mrem for both units.
