r BIG ROCK POINT SEMIANNUAL EFFLUENT REPORT JANUARY - JUNE 1985 This report provides information relating to radioactive effluent releases and solid radioactive waste disposal operations of the Big Rock Point Plant during the period of January through June 1985 in the format contained in Plant Technical Specification 6.9.2.

1

1. Supplemental Information
a. Batch Releases Information relating to batch and continuous releases of liquid and gaseous effluents is provided in Table 1.
b. Abnormal Releases None.

. 2. Gaseous Effluents Table 2a presents a summary of all gaseous radioactive effluents released during the period. Release totals for each radionuclide determined to be

present in gaseous effluents are contained in Table 2b. Gaseous releases of I-132, I-133 and I-135 were determined from the ratios of monthly short-lived halogen analyses to the weekly I-131 analyses. The maximum noble gas release rate was 7.08E+03 uCi/second. There were no I-134 releases.
3. Liquid Effluents Table 3a presents a summary of all liquid radioactive effluents released during the period. Release totals for each radionuclide determined to be present in liquid effluents are contained in Table 3b. The maximum concentration was 1.47E-07 uCi/ml.
4. Solid Waste Table 4 presents a summary of radioactive waste shipped offsite for burial during the period. Total volume of radioactive waste shipped offsite during the first six months of 1985 is 390.0 cubic ft.
5. Radiological Impact on Man Potential doses to individuals and populations were calculated using GASPAR and LADTAP computer codes. The semi-annual totals for curies released were input per nuclide.
a. Doses to individuals in unrestricted areas received from water related exposure pathways are 1.01E-02 mrem maximum total body dose (adult) and 1.65E-02 mrem maximum organ dose'(teenage li r dose).

MIO885-0106A-HP01

b. The maximum offsite air doses are 3.24E-01 mrads for beta and 5.87E-01 mrads for gamma.
c. The most restrictive organ dose is the thyroid dose. The average thyroid dose to individuals within a distance of 50 miles of the site from radioactive iodine and radioactive material in particulate form from major pathways of exposure is 6.90E-04.
d. Total body doses to.the population and average doses to individuals in the population from receiving water related pathways to a distance of 50 miles from the site are 5.57E-03 manRem and 3.62E-05 mrem ~respectively.
e. Total body doses to the population and average doses to individuals in the population from gaseous effluents to a distance of 50 miles from the site are 9.88E-01 manRem and 6.41E-03 mrem respectively.
