RADIOLOGICAL IMPACT ASSESSMENT SEQUOYAH NUCLEAR PLANT JANUARY - DECEMBER 1986 Introduction Potential doses to individuals and populations have been calculated for the time period January 1 through December 31, 1986, 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 1 and 40 CFR 190. The dose calculations have been made using the measured releases listed in tables 1-2 as input in the Gaseous Effluent Licensing Code (for gaseous releases) and the Quarter Water Assessment Code (for liquid releases). Dispersion of radioactive effluents in the environment has been calculated using meteorological data and river flow data measured during this period.
Meteorological Data Meteorologtcal data were measured, and average quarterly joint frequency distributions (JFDs) for ground-level releases were calculated. The ground-level JFD was derived from windspeeds and directions measured 10 meters above ground-level and from the vertical temperature gradient between 10 and 45 meters.
The windspeeds were divided into nine windspeed ranges. For calculational purposes, calms were distributed into the lowest windspeed range (0-0.5 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.
I Gaseous Effluents l Ground-level dispersion models were applied to all releases.
! Radionuclides in gaseous effluents were assumed to be released continuously. Dose estimates for external air exposures were made at the site boundary. External 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. All receptor locations and points of interest are listed in table 2a. 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 1,060,000 persons 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 annulus in which he resides. Doses from milk ingestion were calculated from data on milk production within 50 miles of 0411c
t 4
the plant: site. Doses from externa 1' pathways, inhalation, and beef and
' vegetable ~ ingestion are based on the 50-mile human population
- distribution. ' population dese estimates;for the gaseous effluents are presented in table 11.'
Liquid Effluents Doses from liquid effluents were calculated using' measured hydraulic
- data. The average. river flows at the plant site were 20,300 cubic feet 4
per second (cfs) for the first quarter, 7,900 cfs for the second quarter,.
14,900 cfs for_the third quarter..and 28,700 cfs for the fourth quarter.
- Radioactivity concentrations in the Tennessee River were calculated 4
assuming that releases in'11guld 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
- l assumed to be that calculated at the nearest downstream public water supply (C. F. Industries, Inc.). The maximum potential recreation doses were 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 i
, External gamma radiation levels were 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 l reflect a difference of 2-5 mR/ quarter (average approximately 4 mR/ quarter) between onsite and offsite radiation levels. These higher I 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 l influences.
a
]
, Analysis of environmental TLD data for the period of November 1985 to ~
November 1986 showed that external gamma radiation levels averaged !
- approximately 20.3 mR/ quarter at onsite stations and 16.5 mR/auarter I offsite. This indicates that there was no identifiable increase in dose
)
l rate levels attributable to direct radiation from plant equipment and/or gaseous effluents. Fluctuations in natural background dose rates and in j TLD readings tend to mask any small increments which may be due to plant' I operations.
j Dose Summary I
- Doses calculated for this year result from the low-level effluent j releases of units 1 and 2. For gaseous effluents released in the first I quarter, the maximum gamma and beta air doses were calculated to be
<0.001 and <0.001 mead, respectively. During the second quarter, the j samma and beta air doses were <0.001 and <0.001 mead, respectively. For i the third quarter, the gamma and beta air doses were <0.001 and <0.001 1 mead, respectively. During the fourth quarter the gamma and beta doses were <0.001 mead and <0.001 mead, respectively .

These quarterly doses are well below the annual air dose guidelines (as specified in Appendix 1, to 10 CFR 50) or 20 and 40 mrad for gamma and b2ta radiation, respectively, for two reactor units. The maximum doses from air submersion to the skin and total body during the first quarter were calculated to be <0.001 and <0.001 meem, respectively. During the sscond quarter, the skin and total body submersion doses were <0.001 and
<0.001 meem, respectively. For the third quarter these doses were <0.001 and <0.001 mrem for the skin and total body, respectively. For the fourth quarter, these doses were 0.0 mrem and 0.0 mrem for the skin and total. body, respectively. 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 0.004, 0.014, 0.010, and 0.0097 mrem for the first, second, third, and fourth quarter, rsspectively. These compare with the annual dose guidelines of 30 mrem to the maximum exposed organ. The maximum exposed individual was datermined based on actual existing pathways. Therefore, these doses wsre calculated with consideration of ingestion of meat, milk, and vegetables, inhalation, and exposures to external sources of radiation.
i For liquid effluents released in the first quarter, the maximum individual doses to the adult total body and the maximum exposed organ l
- (child liver) were calculated to be 0.007 and 0.009 mrem, respectively.
j In the second quarter, the maximum doses to the total body and child
- liver were calculated to be 0.018 and 0.021 mrem, respectively. In the third quarter, the maximum doses to the total body and the maximum l
i exposed organ (child bone) were calculated to be 0.038 and 0.044 mrem, j respectively. In the fourth quarter, the maximum doses to the total body j and child liver were calculated to be 0.011 and 0.012 mrem, l respectively. Summing the maximum doses for the four quarters, total
! calculated doses of 0.07 mrem to the total body and 0.09 mrem to the maximum exposed organ were determined. These compare with annual dose guidelines as specified in Appendix 1 to 10 CFR 50 of 6 and 20 mrem to the total body and maximum exposed organ, respectively, for two units.
Maximum organ doses to the population from gaseous effluents during the first quarter were estimated to be 0.021 man-rem to the G.I. tract and 0.022 man-rem to the lung. For the second quarter, population doses were 0.037 to the liver and 0.012 man-rem to the bone. For the third quarter, these doses were 0.037 to the G.I. tract and 0.037 man-rom to the lung, j respectively. For the fourth quarter, these doses were 0.032 to the G.I.
- tract and 0.033 man-rem to the lung.
From liquid releases during the first quarter, the total population along the Tennessee River was estimated to receive 0.6 man-rem to the total body and 0.7 to the maximum exposed organ (liver). For the second quarter, the Tennessee River population was estimated to receive 1.1 man-rem to the total body and 1.7 man-rem to the maximum organ (liver).
For the third quarter, the total population along the Tennessee River was estimated to receive 2.3 man-rem to the total body and 3.6 man-rem to the maxinom organ (liver) . For the fourth quarter, the Tennessee River population was estimated to receive 0.6 man-rem to the total body and 0.8 man-rem to the maximum organ (liver).

)
Population doses can be compared to the natural background dose to the 1,060,000 persons living within 50 miles of the plant of about 159,000 man-rem /yr (based on average individual background dose of about 150 meem/yr).
To determine compliance with 40 CFR 190, the annual dose contributions to the maximum individual from SQN radioactive effluents and all other nearby 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, the total body dose from liquid effluents, and the critical organ does 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 1986 has been calculated to be 0.20 mrem. This is well below the limit of 40 CFR 190 (25 meem/yr).
In addition, no routine activities within the site boundary by members of the public have been identified which would lead to their radiation exposure .
I For the purposes of determining plant performance over its operational period a summary of the quarterly doses for the past five years is presented in table 16. Figures 1 through 5 present this data graphically.
In summary, all annual gaseous and 11guld effluent doses calculated were below tho guidelines of Appendix I to 10 CFR 50 and below the annual limits specified in the SQN Technical Specifications for plant operation.
