JIntr5 duction

--Potential doses to individuals and populations have been calculated lfor the. time period' January 1.through December. 31, 1991 in compliance with the

-requirements of Radiological Effluent Technical. Specification 6.9.1.9.

Dose

[

calculations are based on Regulatory Guides 1.109, 1.111, and 1.113 to determine compliance with the dose objectives contained'in 10 CFR 50 Appendix

_I'and 40 CFR'190. - The calculations have been made using the measured; releases.

-listed in tables 1-2 for radioactivity in both gaseous and liquid effluents.

Dispersion of radioactive effluents in the environment has been calculated 4

Sequoyah-Nuclear Plant-(SQN) loaded fuel and initiated ~startup procedures in

.this reporting period, t

I Meteorological Data '

i

Meteorological data were measured, and average quarterly joint

[

' frequency' distributions (JFDs) for ground-level releases were calculated. The F~-

ground-level JFD_was derived from windspeeds and directions measured 10 meters cabove ground-level and from the vertical temperature gradient between 10 and 45 meters.

Li For calcula-The-windspeeds were' divided into nine windspeed ranges.

tional purposes, ' calms were distributed into the lowest windspeed range (0-0.5 4

mph) according to the directional probabilities in the 0.6-1.4 mph range. The quarterly JFDs are listed in tables 3-through 6 for ground-level releases.

Gaseous Effluents.

t Ground-level dispersion models were applied to all. releases. Radio-nuclides in gaseous effluents were assumed to be released continuously. Dose estimates for external air exposures were made_at the site boundary. External i

doses to the skin and total-body were estimated for the nearest resident in.each sector. Internal doses were estimated for real receptors due to the ingestion, inhalation,' and external exposure pathways. The milk ingestion doses were calculated for farms where milk is consumed without commercial preparation.-

Doses are 'given in tables 7 through 10 for these individual exposure pathways at the maximum exposure locations.

Population doses were calculated for an estimated 1,057,010 persons

-living within a'50-mile radius of the plant site. Population doses were calcu-lated assuming that each individual consumes vegetables and meat produced within

- the sector. annulus in which he resides. Doses from milk ingestion were calcu-

c

-lated 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 11.

t

2 s

Liquid Effluents Doses from liquid effluents were calculated using measured hydraulic data. The' average river flows at the plant site were 17,870 cubic feet per second (cfs) for the first quarter, 15,690 cfs for the second quarter, 23,860-cfs for the third quarter, and 20,740 cfs for the fourth quarter. Radioactivity concentrations in the Tennessee River were calculated assuming that teleases in liquid effluents were continuous.

Doses were calculated for recreation, consumption of 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 water was essumed to be that calculated at the nearest downstream public water supply (C. F. Industries, Inc.).

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 12 through 15.

Direct Radiation

~

External gamma radiation levels are measured by thermoluminescent dosimeters (TLDs) -deployed around SQN during the preoperational period from August 1975 to January 1980, these levels averaged approximately 23 mR/ quarter

.at onsite stations and 19 mR/ quarter offsite. These data reflect a difference of 2-5 mR/ quarter (average approximately 4 mR/ quarter) between onsite and offsite radiation levels. These higher values measured onsite may be attributable to natural variations in environmental radiation levels, earth moving activities

~

onsite,.the mass of concrete employed in the construction of the plant, or other influences.

' Analysis of environmental TLD data for the reporting period showcd that-external gamma radiation levels averaged approximately 19 mR/ quarter at onsite stations and 16 mR/ quarter offsite. This indicates that there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or. gaseous effluents. Fluctuations in natural background dose rates and in TLD readings tend to' mask any small increments which may be due to plant operations.

Dose Summary Doses calculated for this year result from the low-level effluent 1

releases of units 1 and 2.

For gaseous effluents released in the first quarter, 1

.the maximum gamma and beta air doses were calculated to be 2.3x10 and 1.3 mrad, respectively. Duringthesecondquarter,thegammaandbetaairdoseswere

-2

- mrad.

For the third quarter, the gamma

.6.4x10 and 2.8x10 1

and beta air doses'were 2.8x10 mrad and 1.5 mrad. During the fourth quarter 1

-1 the gamma and beta air doses were 1.2x10 mrad and 6.8x10 mrad.

JThese quarterly doses are well below the annual air dose guidelines (as specified Lin Appendix I to~10 CFR 50) of 20 and 40 mrad for: gamma and beta radiation,

"* ].

(respectively,'for'two reactor, units.' The maximum doses from air submersion to

.the skin and-totalLbody during:the first quarter were calculated to'be f3.5x10 1 and 1.8x10~1 mrem. During the second guarter, the skin and total

~ and 4.8x10 mrem, respectively. For the

~

body-submersion doses were. 9.5x10

~1

-1 third quarter'.these_ doses were 4.4x10 mcem'and.2.2x10 mrem for the skin Land total body..'And for the fourth quarter these. doses;were 1.6x10~1 mrem and 2

18;2x10 mrem!for-the' skin and total body. These compare with annual dose guidelines of-30 mrem to the> skin and 10 mrem to the total body.- Internal doses to the maximum exposed organ were estimated to be 2.8x10 ", 2 6x10-2,. 6.4x10 "

~

~

and 3.3x10~". mrem for.the-first, second, third, and fourth quarters, respectively.

The maximumiexposed individual.was_. determined based on actual existing pathwaya.

Therefore,.these' doses were calculated with consideration of ingestion of meat, milk, and~ vegetables inhalation, and exposures to. external sources of radiation.

For'11guid effluents released-in the first quarter, the maximum individual

' doses to the total body and the maximum exposed organ (bone) were calculated to be 0.28 and 6.9 mrem, respectively.. The liquid effluent bone doses calculated

for the first. quarter exceed.the guidelines of Appendix-I to 10 CFR 50 (5 mrem /

quarter for: one reactor unit)..The calculated bone doses are~due almost entirely

-to reported levels of phosphorus-32-(P-32) in the liquid effluent. During this quarter, operation of radwaste equipment was ' initiated to reduce P-32 ' releases.

~~~

Since that. time calculated doses have been well below limits.

P-32, via the fish pathway, 'was and is still the ~ 1argest contributor: to dose. Data from completed and' ongoing programs are being evaluated by TVA and other groups to determine the T

validity of these calculated releases and. doses. By assuming immediate consumption of fish caught just downstream of-Sequoyah;and an intake rate of one-pound / week of fish containing P-32.at effective-levels 25,000-times those in water, the calculated" doses lare hypothetical in nature and are not known to have been received by rea1' individuals. In the second quarter, the maximum-doses to the total body and bone were calculated to be 0.06 and 0.34 mrem, respectively. In the third quarter, the maximum doses to the total body and bone were calculated to be 0.16

.and 0.99. mrem,-respectively.

In-the fourth quarter, the maximum doses to the total body and bone were calculated to-be 0.03 and 0.30 mrem, respectively.

' Summing the. maximum doses for the four quarters, total calculated doses of 0.53 mrem to the total body and 8.5 mrem to the bone were determined. These compare with annual dose guidelines as specified in Appendix-I to 10 CFR 50 of 6 and 20 mrem to the total body'and maximum exposed organ (bone), respectively, for two units.

~

Population doses from gaseous effluents during the first quarter were estimated to be 1.2x10~0 ' man-rem to the total' body and 1.2x10 man-rem to the

~0

' thyroid.< For'the'second quarter, population doses were 1.8x10~1 man-rem to the 1

is total body-and 2.3x10 man-rem to the thryoid.

For the third quarter these doses were 7.3x10~1 and 7.4x10 man-rem for the total body'and thyroid, respectively.

, IFrom liquid releases' during' the -first quarter, the total population clong.the Tennessee River was estimated to receive 5.0 man-rem to the total body.and A20 to the maximum exposed orgsn (bone). For the second. quarter, the g.

. Tennessee-River population was estimated to receive 1.6 man-rem to t e total 8

h body and,6.2' man-rem to bone. For the third quarter, the total population clong.the Tennessee River was estimated to receive 4.7 man-rem to the total body and 22 man-rem to bone. For the-fourth. quarter, the Tennessee River population

.was estimated to-receive 0.98 man-rem to the total body and 6.5 man-rem to bone.

~

Population doses can be compared to the natural background dose to the

~

'1,057,010 persons living within 50 miles of the plant of about.159,500 man-rem /yr.

In summary a11' doses calculated were below thejguidlines of 10 CFR.50 Appendix I

and below the'ltaits specified in.the SQN Technical Specifications for plant

-operation.

To determine compliance with 40 CFR 190, the annual dose contributions

~

to the maximum individual from SQN radioactive' effluents and all other nearby 1 uranium ~ fuel-cycle sources have been considered. No nearby fuel-cycle facilities other than SQN have been identified which would significantly expose the maximum individual..The dose to the maximum individual-has been. conservatively estimated

. by; first, ' summing the total-body air submersion dose, the critical organ dose from gaseous effluents, and the total body and. critical organ dose from liquid effluents (direct radiation, as reported above, is not identifiable over

~

background levels) for each' quarter; then, taking the sum for each quarter and summing over four quarters. Using'this method the total dose to the-maximum individual-for the twelve consecutive months in 1981 has been calcue 11ated to be 9.6 mrem.. This is below the ' limit of 40.CFR 190 (25 mrem /yr)

~

LIn' addition, no routine activities within the site boundary by members of-the public have been-identified which would lead to their radiation exposure.

For the purposes of. determining plant performance over its operational

-period'a summary of the quarterly. doses for the past'two years is presented in

. table 16.

In; summary, all annual gaseous and liquid effluent doses calculated were below the guidelines of Appendix I to 10 CFR 50 and below the annual limits specified in-the.SQN Technical Specifications for plant operation.
