RADIOLOGICAL IMPACT ASSESSMENT SEOUOYAH NUCLEAR PLANT JANUARY - DECEMBER 1987 Introduction Potential doses to individuals and populations have been calculated for the time period January 1 th' ough becember 31, 1987, in compliance with J
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 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 Meteorological 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.
Gaseous Effluents Ground-level dispersion models were applied to all releases.
Radionuclides in gaseous affluents were assumed to be released continuously.
Dose estimates for external air arposures 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 i
for real receptors due to the ingestion, inhalation, and arternal i
exposure pathways.
The milk ingestion doses were calculated for farms where milk is consumed without commercial preparation.
All receptor i
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.
l 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 i
l
...l..
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.
Liquid Effluents Doses from liquid effluents were calculated using measured hydraulic data. The average river flows at the plant site were 39,600 cubic feet per second (cfs) for the first quarter, 22,400 cfc for the second quarter, 24,300 cfs for the third quarter, and 17,600 cfs for the fourth quarter.
Radioactivity 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 tetween the plant site and the mouth of the Tennessee River. The maximum individual dose from drinking water was 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 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 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.
I Analysis of environmental TLD data for the period of November 1986 to November 1987 showed that external samma radiation levels averaged approximately 19.1 mR/ quarter at onsite stations and 16.4 mR/ quarter offsite.
This indicates that there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or I
gaseous effluents.
Fluctuations in natural background dose rates and in l
TLD readings tend to mask any small increments which may be due to plant operations.
Dose Summary l
l Doses calculated for this year result from the low-level effluent l
releases of units 1 and 2.
For gaseous effluents released in the first quarter, the maximum gamma and beta air doses were calculated to be l
<0.001 and <0.001 mrad, respectively.
During the second quarter, the samma and beta air doses were <0.001 and <0.001 mead, respectively.
For f
the third quarter, the gamma and beta air doses were <0.001 and <0.001 mead, respectively.
During the fourth qu,arter the gamma and beta doses were <0.001 mead and <0.001 mead, respectively.
0411c
I These quarterly dtsen cre well belev the annual cir dose guidelines (es sp cified in Appendix I, to 10 CFR 50) or 20 and 40 trad for gamma and beta 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 0.0 and 0.0 area, respectively.
During the second quarter, the skin and total body submersion doses were 0.0 and 0.0 mram, respectively.
For the third quarter these doses were 0.0 and 0.0 mram for the skin and total body, respectively.
For the fourth quarter, these doses were 0.0 mram and 0.0 mram for the skin and total body, respectively.
These compare uith annual dose guidelines of 30 mram to i
the skin and 10 mram to the total body.
Internal doses to the maximum exposed organ (the child GI tract) were estimated to be 0.004, 0.006, 0.008, and 0.006 mram for the first, second, third, and fourth quarter, respectively.
These compare with the annual dose guidelines of 30 mram to the maximum exposed organ. The maximum exposed individual was determined based on actual existing pathways.
Therefore, these doses were calculated with consideration of ingestion of meat, milk, and vegetables, inhalation, and exposures to external sources of radiation.
For liquid effluents released in the first quarter, the maximum individual doses to the adult total body and the maximum exposed organ (adult liver) were calculated to be 0.002 and 0.003 mram, respectively.
In the second quarter, the maximum doses to the adult total body and child bone were calculated to be 0.017 and 0.021 area, respectively.
In the third quarter, the maximum doses to the adult total body and the maximum exposed organ (child bone) were calculated to be 0.084 and 0.095 mrem, respectively.
In the fourth quarter, the maximum doses to the adult total body and child bone were calculated to be 0.034 and 0.039 mrem, respectively.
Summing the maximum doses for the four quarters, total calculated doses of 0.14 mram to the total body and 0.16 mrem to the maximum exposed organ were determined.
These compare with annual dose guidelinas as specified in Appendix I 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 0.012 man-rem to the G.I. tract and 0.013 man-rem to the lung.
For the second quarter, population doses were 0.019 to the G. I. tract and 0.020 man-rem to the lung.
For the third quarter, these doses were 0.035 to the G.I. tract and 0.036 man-rem to the lung, respectively.
For the fourth quarter, these doses were 0.023 to the G.I. tract and 0.025 man-rem to the lung.
From liquid releases during the first quarter, the total population along the Tennessee River was estimated to receive 0.15 man-rem to the total body and 0.23 to the maximum exposed organ (liver). For the second quarter, the Tennessee River population was estimated to receive 0.76 l
man-rem to the total body and 0.95 man-rem to the maximum organ (bone).
For the third quarter, the total population along the Tennessee River was estimated to receive 5.0 man-rem to the total body and 7.0 man-rem to the maximum organ (liver).
For the fourth quarter, the Tennessee River population was estimated to receive 1.8 man-rem to the total body and 2.6 man-rem to the maximum organ (liver).
=
P2pulcti:n dtses can be comparcd to the'naturci backgr und dsse to the 1,060,000 persons living within 50 miles of the plant of about 159,000 man-ren/yr (based on average individual background dose of about 150 area /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 j
total body air submersion dose, the critical organ dose from gaseous effluents, the total body dose from liquid affluents, and the critical organ does from liquid effluents (direct radiation, as reported above, is not identifiable over background levels) for pach quarter; then, taking the sua for each quarter and summing over four quarters. Using this method, the total dose to the maximum individual for the twelve consecutive months in 1987 has been calculated to be 0.32 area. This is well below the limit of 40 CFR 190 (25 area /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.
For the purposes of deternining 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 liquid effluent doses calculated were i
below the guidelines of Appendix I to 10 CFR 50 and below the annual limits specified in the SQN Technical Specifications for plant operation.
