ltADIOLOGICAL IMPACT ON MAN Sampling and analysis of liquid and gaseous effluents were performed in accordance with the frequencies, types of analysis, and Lower Limit of Detection (LLD) outlined in the PNPP Unit 1 Technical Specifications.

Radioactive material was detected in some of the liquid and gaseous effluent samples analyzed.

Dose calculations, using measured effluent flow and meteorological data, resulted in dose to individuals at levels below 10CFR20 and 10CrR50, Appendix I limits.

Direct radiation resulting from plant operation, as measured by environmental thermoluminescent dosimeters located around the plant, did not contribute any measurable dose to members of the public for the reporting period and, as there are no other nearby fuel cycle sources, 40CTR190 limits were not exceeded.

Summaries of maximum individual and population doses resulting from liquid and gaseous radioactive effluent releases are given, in Regulatory Guide 1.21 format, in.

Technical specification 6.9.1.7 requires assessment of radiation doses from radioactive liquid and gaseous effluer.t to members of the public while onsite.

These onsite doses are assessed relative to offsite dose values, and are adjysted for appropriate dilution, dispersion, and occupancy facttrs.

ONSITE DOSE FOR LIQUID EFFLUENTS The onsite liquid effluent pathway of concern for members of the public is shore exposure while fishing along the Lake Erie coast.

Occupancy is assumed to be 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> per year and the dilution factor for the point of exposure is 10.

Ratioing this exposure pathway to doses calculated for offsite locations yields the following onsite dose values.

e ONSITE DOSE FOR GASEOUS ErrLUENTS i

'Several cases are considered f or onsite gaseous ef fluent exposure to members of the public including traversing a 1

public road within the site boundary, shoreline fishing, non-plant related training, car pooling, and job interviews.

The onsite activity with the highest dose potential, relative to gaseous effluents, is shoreline fishing.

Occupancy is again assumed to be 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> per year.

Accounting for this and the difference between annual average disgersion values for the onsite point of concern, 6.6 E-05 s/m (a unity occupancy factor is assumed for this calculation), the following maximum onsite dose values are generated.

Total Body Organ Quarters 1 & 2 2.8 E-03 mrem 1.6 E-02 =~"-; thyroid)

Quarter 1 2.8 E-03 mrem 1.6 E-02 M(thyroid)

Quarter 2 1.3 E-06 mrem 2.2 E-04 a6em(thyroid)

AVERAGE INDIVIDUAL TOTAL BODY DOSES Average total body dose to individual members of the public is determined for the population that lives within fifty miles of the plant for gaseous effluents (2.42 E+06 persons) and the population that receives drinking water from intakes within fifty miles for liquid effluents (2.37 E+06 persons).

These doses are calculated using the total population dose figures found in Attachment 1.

Gases Liquids Quarters 1 & 2 3.8 E-06 mrem 1.5 E-04 mre Quarter 1 3.8 E-06 mrem 4.8 E-05 mrem Quarter 2 9.1 E-11 mrem 1.0 F.-04 mrem Gaseous and Air Dose calculatione at the site boundary were performed for two cases.

AttactAJnt 1 provides the calculated maximum site boundary dose values for all sectors including those sectors which are totally over water in which no member of the public resides (These are the W, WNW, NW, NNW, N AND NNE SECTORS). provides the calculated maximum site boundary dose values for the land based sectors in which members of the public reside.

LIouID ErrLUENTS For the first quarter of.'989 there were 78 batch and 27 continuous releases.

Batce release total waste volume for the first quarter was 8.6 E<6 liters; total continuous release waste volume was 5.1 E+9 liters; total plant discharge during periods of release was 2.8 E+10 liters.

For the second quarter of 1989 there were 87 batch and 45 continuous releases.

Batch release total waste volume for the second quarter was 1.0 E+7 liters; total continuous release waste volume was 6.4 E+9 liters; total plant discharge during periods of release was 3.9 E+10 liters.

Summaries of the radionuclide total curie activities, average diluted concentrations, and percentage of MPC (in Regulatory Guide 1.21 format) are included in Attachment 4.

If a radionuclide was not detected, zero activity was used for that isotope in dose calculations.

A zero activity indicates that the radionuclide was not present at a level greater than the Lower Level of Detection (LLD) of the instrumentation used.

In all cases, these LLDs were less than the levels required by Technical Specifications.

The following are typical LLDs.
