ATTACHMENT 1 Tf1I-2 QUARTERLY DOSE ASSESSMENT REPORT FOURTH QUARTER 1988 4410-89-L-0026 EXECUTIVE SUfEARY Three Mile Island Nuclear Station Unit 2 Effluent and Offsite Dose Report for the Period of October 1,1988 to December 31, 1988 This report summarizes the radioactive liquid and gaseous releases (effluents) from Three Mile Island Unit 2 and the calculated maximum hypothetical radiation exposure to the public resulting from these releases.

This report covers the period of operation from October 1 to December 31, 1988.

Radiological releases from the plant are measured by installed plant monitors sampling the plant stack for gaseous releases and liquid monitors for discharges to the Susquehanna River.

These monitors 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 the plaat.

The use of real-time meteorological information permits the determination of both the direction in which the release traveled and the dispersion of radioactive material it 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, Susquehanna 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 Exposure to the public from consumption of water and fish withdrawn from the Susquehanna River downstream of the plant is also calculated.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 eiich 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 and consumption.

ATTACHMENT 1 TMI-2 QUARTERLY DOSE ASSESSMENT REPORT 4410-89-L-0026 FOURTH QUARTER 1988 Page 2 of 2 L'iquid discharges made during the reporting period October 1 to December 31, 1988 consisted of 0.0001 curies of tritium, 0.00007 curies of strontium-90 and unidentified beta activity, and 0.00006 curies of cesium-137.

Unidentified beta activity is treated as strontium-90 for the purpose of dose calculations.

These release rates and quantities are consistent with results of previous quarters.

The quantities of each radionuclides released are actually up to 1 million times smaller than the normally existing environmental quantities that flowed past the Klant during the same time period.

During the reporting period October 1 to December 31 of 1988, the maximum hypothetical calculated whole body dose to an individual due to liquid effluents from Three Mile Island Unit 2 was about 0.00099 millirem.

The maximun hypothetical calculated dose to any organ of an individual was 0.002 millirem to the bone.

Airborne discharges made during this same time period consisted of 4 curies of tritiurt, 0.00001 curies of cesium-137, 0.08 curies of krypton-85, 0.00000004 curies of strontium-90, and 0.00003 curies of unidentified beta activity.

l Unidentified beta activity is, as with liquid effluents, conservatively assumed J

to be entirely strontium-90. These release rates and quantities are also consistent with the results from previous reporting periods.

The maximum hypothetical dose to an individual due to gasecus effluents was about 0.0023 millirem to the bone of a child.

The maximum hypothetical whole body dose received by any individual from effluents from the Three Mile Island Nuclear Station Unit 2 for the latest reporting period is 12,000 times lower than the dose the average individual in the Three Mile Island area receives from natural background during the same time period.

Natural background averages about 25 millirem whole body per quarter in the Three Mile Island area and average equivalent dose from natural radon is about 50 millirem per quarter for a total of about 300 mrem per year.

The doses which could be received by the maximum hypothetical individual are at most 0.1 percent of the guides established by the Nuclear Regulatory Commission.

THI-2 QUARTERLY DOSE ASSESSMENT REPORT ATTACHMENT 4-FOURTH QUARTER 1988 4410 L-0026 Page 1 of 2 INTERPRETATION OF DOSE

SUMMARY

TABLE' The Dose Sumary Table presents the maximum hypothetical doses to an individual and the general population resulting from the release of gaseous and liquid effluents from THI-2 during the fourth quarter reporting period of 1988.

A.

Liquid (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-2 are drinking water, 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 " 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.

After calculating the doses to all age groups for all eight organs resulting from 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 tne fourth quarter of 1988 the calculated maximum whole body dose received by anyone would have been 9.9E-4 mrem to an adult.

Similarly, the maximum organ dose would have been 2.0E-3 mrem to the bone of an adult.

8.

Gaseous (Individual)

There ere seven majer 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) meat, 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 beyond 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.

Direct noble gas plume dose to the maximum individual is shown on lines 5 and 6.

For the fourth quarter of 1988, the noble gas individual doses are from krypton-85 releases as a result of plasma arc cutting in the reactor vessel. The calculated maximum wnole body dose to an individual would have been 2.8E-7 mrem.

The calculated maximum dose to the skin would have been 3.3E-5 mrem.

a

Tfil-2 QUARTERLY DOSE ASSESSMENT. REPORT ATTACHMENT 4 FOURTH QUARTER 1988 4410-89-L-0026 Page 2 of 2 The Iodines and Particulate section described in line 7 represents the

' maximum exposed organ due to iodine and particulate. This does not include any plume exposure which is separated out by lines 5 and 6.

The doses presented ir. this section !;ain reflect the maximum exposed organ for the appropriate age group.

The fourth quarter 1988 iodine:; and particulate would have resulted in a-maximum dose of 2.3E-3 mrem to the bone of a child residing 700 meters from the site in the E 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 distance of 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 fourth quarter, liquid effluents resulted in a whole body population dose of 0.028 person-rem.

The maximum critical ergan population dose to the bone was 0.11 person rem.

Gaseous effluents resulted in a whole body population dose of 0.013 person-rem.

Maximum organ population dcse to the bone, thyroid, lung, kidney, liver and GI was 0.011 person rem.

Operating License No. DPR-73 Docket No. 50-320 Quarterly Dose Assessment Report - Fourth Quarter.1988 Semi-Annual Radioactive Effluent Release Report Per Section 5.6.1.C of Appendix B to the Recovery Technical Specifications, the quarterly report of radiological releases and estimated doses is submitted. is an executive su : nary of TMI-2 effluents and doses reported in Attachments 2 and 3. presents a summary of releases including estimates of total activity and the time rate of release of each nuclide. is a Dose Summary Table which provides a summary of the maximum hypothetical doses to individuals and the general population resulting from TMI-2 activities for the Fourth Quarter 1988 and the entire year c71988. is an interpretation of the Dose Summary Table for the Fourth Quarter 1988. Doses were developed from calculational models and represent the bounding dose for all cases., in accordance with the requirements of 10 CFR 50.36(a)(2), is the Radioactive Erfluent Release Report for TMI-2 for the Third and Fourth Quarters of 1988. Table 18, " Effluent and Waste Disposal Semi-Annual Report, Gaseous Effluent-Elevated Releases," is not included as release paths at TMI-2 do not meet the Regulatory Guide 1.109 definition of an elevated release and are considered ground level releases.

4 Dose summaries and effluent releases for the previous cuarters of the 1988 l

calendar year were submitted via GPU Nuclear letters 4410-88-L-0089, dated l

l May 27, 1988; 4410-88-L-0142, dated August 29, 1988; 4410-88-L-0184, dated November 29, 1988; and 4410-89-L-0022 (update), dated February 22, 1989.
