NORTHERN STATES POWER COMPANY PRAIRIE ISLAND NUCLEAR GENERATING PLANT OFFSITE RADIATION DOSE ASSESSMENT FOR January 1 - December 31, 1985 An assessment of radiation dose due to releases from the Prairie Island Nuclear Generating Plant during 1985 was performed in accordance with the Technical Specifications. Computed doses were well below the 40 CFR Part 190 and 10 CFR Part 50, Appendix I standards and guidelines, j

Offsite dose calculation formulas and meteorological data were used from the Offsite Dose Calculation Manual in making this assessment. Source terms were obtained from the two Effluent and Waste Disposal Semi-Annual reports prepared for NRC review during the year.

Offsite Doses from Gaseous Release Computed doses due to gaseous releases are reported in Table 1.

Critical receptor location and pathways for organ doses are reported in Table 2.

i Doses, both whole body and organ, are a small percentage of Appendix I guidelines.

Offsite Doses from Liquid Release Computed doses due to liquid releases are reported in Table 1.

Receptor information is reported in Table 2.

Doses, both whole body and organ, are a small percentage of Appendix I guidelines.

Doses to Individuals Due to Activities Inside the Site Boundary Occasional sportsmen will enter the Prairie Island site for recreational activities. These individuals are not expected to spend more than a few hours per year within the site boundary. Commercial and recreational t

river traffic exists through this area.

For purposes of estimating dose due to recreational and river trans-portation activities within the site boundary, it is assumed that the limiting dose within the site boundary would be received by an individual who spends a total of seven days per year on the river just off shore from the main plant buildings (ESE at 0.2 miles). Whole body 1

and inhalation organ doses were calculated for this location and occupancy time.

These doses were reported in Table 1.

Doses to Most Exposed Member of the General Public from l

Reactor Releases and Other Nearby Uranium Fuel Cycle Sources There are no uranium fuel cycle facilities in the vicinity of the Prairie Island site.

The only other source of exposure to the general public in addition to the plant gaseous and liquid effluents is from direct radiation.

Pressurized water reactor direct radiation has been shown to be negligible. An array of TLD monitoring locations at the site boundary has consistently indicated that plant operation in recent years has had no effect on ambient gamma radiation.

Therefore, the most exposed member of the general public will not receive a radiation dose from reactor releases and all other fuel cycle acti-vities in excess of the sum of the liquid and gaseous whole body and organ doses reported in Table 1 for the site boundary and critical receptor, respectively. These doses are well within the 40 CFR Part 190 standards of 25 mrem to the whole body or any organ (except the thyroid) and 75 mrem to the thyroid every 12 months.
