RADIOLOGICAL IMPACT ASSESSMENT BROWNS FERRY NUCLEAR PLANT JANUARY-JUNE, 1976 Introduction Potential doses to individuals and populations have been calcu-lated for the time period January 1 through June 30, 1976. The calculations have been made using the measured releases listed in Tables 1 and 2.for radioactivity in both gaseous and liquid effluents. Dispersion of radio-active effluents in the environment has been calculated using meteorological data and river flow data measured during this per'iod.
Meteorolo ical Data Meteorological data were measured, and average quarterly joint frequency distributions (JFD's) for ground-level and stack releases were calculated. The ground-level JFD was derived from wind speeds and direc-tions measured with a sensor located 33 feet above ground level and from the vertical temperature gradient between 33 and 150 feet., The JFD's for elevated releases were based on, wind directions and wind speeds measured at 300 feet. Stability class D was assumed to persist at the effluent release level of 600 feet for the entire period. Examination of rawinsonde data from TVA's'olbert Steam Plant (40 miles west of BFNP) indicates that AT-based stabilities at levels above 600 feet are usually neutral with occasional occurrence of stability class E. Inversions at those heights occur infrequently and 'are usually short-lived.
The wind speeds were divided into nine wind-speed ranges. For calculational purposes, calms were. distributed into the lowest wind speed range (0-0.5 mph) according to the directional probabilities in the 0.6-1.4 mph range. The quarterly JFD's are listed in Tables 3 and 4 for ground-level releases and in Tables 5 and 6 for elevated releases.
Gaseous Effluents Ground-level and elevated (stack) dispersion models were used to estimate radioactivity concentrations in the environment. Radionuclides in gaseous effluents were assumed to be released continuously. Dose esti-mates for external air exposures were made at the site boundary. External doses to the skin and total body were estimated for the nearest residence in each sector. Internal, doses to the thyroid were estimated from the ingestion, inhalation, and external exposure pathways. The internal doses were calculated for farms where milk is consumed without commercial prepa-ration. Doses are given in Tables 7 and 8 for these individual exposure pathways 6t the maximum exposure locations.
Population doses were calculated for an estimated 627,000 per-I sons living within a 50-mile radius of the plant site. Population doses were calculated assuming that each individual consumes vegetables and meat produced within the sector annuli in which he resides. Doses from milk ingestion were calculated from data on milk production within 50 miles of the plant site. Doses from external pathways, inhalation, and beef and vegetable ingestion are based on the 50-mile human population distribution. Population dose estimates for the gaseous effluents are presented in Table 9.
Li uid Effluents Doses from liquid effluents were calculated using measured P
hydraulic data. The average river flows at the plant site were 57,200 cfs for the first quarter and 31,300 cfs for the second quarter. Radio-activity concentrations in the Tennessee River were calculated assuming that releases in liquid effluents were continuous'.
Doses were calculated for recreation, consumption of fish, and drinking water from public water supplies be'tween the plant site and the mouth of the Tennessee River. The maximum individual dose from drinking water was assumed to be that calculated for the nearest downstream public water supply (Champion Paper Company). The maximum potential recreation dose was calculated for a location immediately downstream from the plant outfall. Dose estimates for the liquid effluents are presented in Tables 10 and 11.
Direct Radiation Statistical analysis of thermoluminescent dosimetry (TLD) data accumulated at both onsite and offsite locations during the first and second quarters has indicated no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous efflu-ents. Fluctuations in natural background dose rates and in TLD readings tend to mask any small increments which may be due to plant operations.
An experimental program has been initiated using" high-pressure P
ionization chamber measurements to relate reactor power level to direct
radiation dose rates. Since the plant has not operated .since March 22, 1975, results of this work are not available for estimating dose rates during this reporting period.
Dos~eSummar Doses calculated for this semiannual period result from the low-level effluent releases of Units 1 and 2. Since Browns Perry has not operated since March 22, 1975, only residual activity in radwaste systems has been released. Por gaseous effluents released in the first quarter, the maximum gamma and beta air doses were calculated to be .042 and .17 mrad, respectively. During the second quarter, the gamma and beta air doses were .082 and .57'mrad, respectively. These quarterly. doses are well below the annual air dose limits (as specified in Appendix I to 10 CFR 50) of 20 and 40, mrad for gamma and beta radiation, respectively, for two reactor'nits. The maximum doses from external sources to the skin and total body during the first quarter were calculated to be .06 and .17 mrem. During the second quarter, the skin and total body doses were .19 and .082 mrem, respectively. These compare with annual dose limits of 30 mrem to the skin and 10 mrem to the total body.. Internal doses to the maximum exposed organ, i.e., the thyroid, were estimated to be .91 and .054 mrem for the first and second quarter. These doses result from the ingestion of milk, meat, and vegetables, inhalation, and from exposures to external sources of radiation.
For liquid effluents released in the first quarter, the maximum
.doses to the total, body and the maximum exposed organ, i.e., G.I. tract,
4 were calculated to be .003 and .006 mrem, respectively. In'the second quarter, the maximum doses to the total body and G.I. tract were .004 and
.Ol mrem, respectively. These compare with annual dose limits as specified in Appendix I to 10 CFR 50 of 6 and 20 mrem to the total body and maximum exposed organ (G.l. tract), respectively.
Population doses from gaseous effluents during the first quarter were estimated to be .055 man-rem to the total body and 1.5 man-rem to the thyroid. For the.-second quarter, population doses were .042 man-rem to the total body and .22 man-rem to the thyroid.
From liquid releases during the first quarter, the total popu-h lation along the Tennessee River was estimated to receive .17 man-rem to the, total body and .44 man-rem to the G.I. tract. For the second quarter, the Tennessee River population was estimated to receive .'24 'man-rem to the total body and .68 man-rem to the G.I. tract.
In summary, the external air doses and external doses to the skin and total body from gaseous effluents were less than .01 mrad and mrem per quarter, respectively. Doses from liquid effluents were less than .Ol mrem per quarter. Population doses from gaseous effluents were a maximum of 1.5 man-rem per quarter to the thyroid. Population doses 'from liquid effluents to any organ were less than 1.0 man-rem per quarter. All doses calculated were below the limits of Appendix I to 10 CFR 50 and well below the limits specified in the Browns Ferry Nuclear Plant technical specifi-cations for plant, operation.
