RADIOLOGICAL IMPACT ASSESSMENT BROWNS FERRY NUCLEAR PLANT JANUARY-JUNE 1975 Introduction Potential doses to individuals and populations have been calcu-lated for the time period January 1 through June 30, 1975.

The calculations have been made using the measured releases listed in Tables 1 and 2 for f

radioactivity in both gaseous and liquid effluents.

Dispersion in the I

environment has been, calculated using'eteorological data and river flow data measured during this period.

Meteorolo ical Data Meteorological data were measured, and average quarterly goint-frequency distributions (JFD's) appropriate for elevated releases and for ground-level releases were calculated.

The ground-level JFD was derived from.wind speeds-and directions measured with a sensor located 33 feet above giound level and from the vertical temperature gradient between 33 and 150 feet.

The elevated JFD was determined using a wind sensor located 300 feet above ground level and the vertical temperature gradient between 33 and 300'eet.

Atmospheric stability was classified as indicated in Table 3.

The wind speeds were divided into nine ranges.

For calculational

purposes, calms were distributed in 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 4 through 7.

Gaseous Effluents

]n~

the environment.

Radionuclides in gaseous effluents were assumed'to be released continuously.

Dose estimates for external exposure and inhalation were made for. a hypothetical adult constantly standing unsheltered at the P

giP h'CJgll 1c "ill site boundary.

Adult ingestion doses were calculated for padioiodines in tlat 1 ":'*)n milk and leafy vegetables produced at the site boundary.

Potential child-

'll g f +Pl,~

9 w w "~f.'~

thyroid ingestion doses were calculated for the most critical real-cow location.

The child inhalation dose was calculated assuming exposure at the site boundary.

Population doses and average individual doses were constant ca3,culated for an estimated 627,000 persons living within a 50-mile radius;of-.the,>><<

plant site.

Population ingestion doses were calculated assuming> that each individual drinks fresh milk and eats leafy vegetables produced" near his residence.

For comparison, a population thyroid dose.,estimate, was calculated based on data for milk production within 50 miles of the'lant site.

Dose estimates for the gaseous effluents are presented in Tables 8 and 9.

Li uid Effluents Doses from liquid effluents were calculated using measured 8 ~

hydraulic data.

The average river flows at the plant site were 108,000 cfs for the first quarter and 55,000 "cfs for the second quarter.

Radioactivity concentrations in the Tennessee River were calculated assuming that releases in,liquid effluents were continuous.

Doses were calculated for recreation, eating fish, and drinking water from public water supplies between the plant site and the mouth of the Tennessee River.

The maximum individual dose from drinking ~ater 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 during the first and second quarters at onsite and offsite locations has indicated no significant increase in dose rate levels attributable to direct radiation from 'plant equipment and to gaseous I

effluents.

Large fluctuations in natural background dose rates and in TLD IC II readings tend to mask any small increments due to plant operations.

A prospect has been initiated to relate reactor power level to direct radiation dose rates offsite using high-pressure ionization chamber measurements.

However, because the plant has not operated since March 22, 1975, results of this work are not yet available for estimating dose rates during this reporting period.

Dose Summar Xn the first quarter, the maximum site boundary doses were calculated to be 2.9 mrem to the skin and 0.99 mrem to the total body.

A potential child's thyroid dose was calculated to be 2.2 mrem.

Popula-tion doses were estimated to be 5.6 man-rem to the skin and 1.0 man-rem to the total body.

For '.the second quarter, calculations ind'icated that potential site !boundary doses"were 10 mrem,to 'the skin:and '5 mrem.to the total body.

'Potential ch'ild '.thyro'id.doses, were 'calculated '.to be.'2.'4.mrem.

'Potential skin,:and 'total 'body-doses to the population 'were estimated:.to 'be '15 and 1.6.man-rem, respect'ively.

The ~a)ority,of the doses ~were due.to."gaseous ~effluents released Xrom.the plant'.

The.doses from 3.iqu'id:effluents:.and direct

radiation were very small..

'The potential doses;are;well

.below the. limits specified in.the Browns 'Perry.Nuclear Plant "technica1 speci'ficat'ion's for plant -operat'ion.
