Astiological Impact Assessment Sequoyah Nuclear Plant January - December 1989 INTRODUCTION Potential doses to maximum individuals and the population around Sequoyah are calculated for each quarter as required in Technical Specification Section 6.9.1.9. Measured plant releases for the reporting period are used to estimate these doses. Dispersion of radioactive effluents in the "
-environment is estimated in accordance with the guidance provided by Regulatory Guides 1.109, 1.111 and 1.113 using meteorological data and riverflow data measured during the period. Using dose calculntion methodologies which are described in detail in the Sequoyah Offsite Dose Calculation Manual, the doses are calculated and used to determine compliance with the dose limits contained in Sequoyah's Operating
' License. . In this report, the doses resulting from releases are described ,
and compared to quarterly and annual limits established for Sequoyah. j
SUMMARY
0F LIQUID AND GASEOUS EFFLUENT RELEASES - 1989 Although nuclear plants are designed tn contain the radioactive material created by the fission process, small amounts of this material escape from the fuel rods. Also, very small amounts of the structures and components of the systems become activated through the bombardment of neutrons and are-worn away. -This radioactive material can be transported throughout plant systems and released to the environment.
Effluent Monitoring Plant paths through which radioactivity is released are monitored. Th e s e..-
monitors record the radiation levels for each release. Monitors which E^ '
are used.for liquid releases:will automatically alarm and stop any release which is above regulatory limits. Gaseous release monitors also provide alarming mechanisms to allow for the termination of any release above limite.
Airborne Releases The noble gas fission products do not mix with water and are given off in a gaseous form. A very small amount of solid radioactivity is given off along with these noble gases. These releases are processed so that the radioact.ive material is filtered and/or decayed prior to release through the plant vents. Sampling and monitoring methods are used to determine H the amount of radioactive material released. If these methods indicate that radioactivity in

airborne effluents above preset limits, then releases are ,
terminated. Airborne releases for each quarter in 1989 are listed i M ,.
in Table,1.
Liquid Releases Some small amounts of radioactive material migrate into the primary coolant water. The primary coolant water is routed through a purification system to remove most of these particles; however, not all are removed. Some of the radioactive liquids may leak from pipes or valves in the system. These liquids are collected in floor and equipment drains and sumps. The collected liquids are then processed through a clean-up system, composed of storage tanks, recycling systems, and demineralizers,-to remove contaminants. The q purified water is then monitored to determine the amount of .
radioactive material remaining in the water prior. to its release.
Steps are taken to ensure that the amount of radioactivity released to the environment is as low as reasonably achievable (ALARA). If F the levels of radioactivity are above preset limits, the releases ,
N' '
- are c'irculated'through-the clean-up-system again for additional processing.- All radioactivity released from the plant into the Tennessee River is quantified prior to release. Liquid releases for each quarter in 1989 are given in Table 2.
l l
DOSE LIMITS The U.S. Nuclear Regulator Commission (NRC) requires. nuclear power plants to be designed, built,. and operated in such a way that thn levels of radioactive material released into unrestricted areas.is as low as reasonably achievable (ALARA). To ensure that this is done, the plant's operating license includes Technical .
Specifications which govern the release of radioactivity. These ,
c Technical Specifications specify limits for the release of
- * "- radioactive ef fitients, as well as limits. for doses to the general . l public from the release of these effluents. These limits are set.
well below the NRC 10 CFR 20 limits which govern the concentrations I
-of radioactivity and exposures permissible in unrestricted areas.
This ensures that radioactive effluent releases are ALARA.
The Technical Specification limits for doses at or beyond the site boundary from airborne noble gases releases are:
Less than or equal to 5 mrad per quarter and 10 mrad per year for gamma radiation,
- and -
Less than or equal to 10 mrad per quarter and 20 mrad per year for beta radiation.

- L'ess.than or equal to 7.5 mrem per quarter and 15 mrem per year to any organ.
The Technical Specification limit for doses to a member of the general public from radioactive material in liquid effluents released to unrestr.icted areas, is: !

- and -
Less than or equal to 25 mrem per year to any other organ.
E DOSE CALCULATIONS Estimated doses to the public are determined using computer models (the Caseous Effluent Licensing Code, GELC, and the Quarterly Water
, Dose Assessment Code, QWATA). These models are based'on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113).
-for determining the potential dose to individuals and populations living in the vicinity of the plant. The area around the plant is analyzed to determine the pathways through which the public may receive a dose. The doses calculated are a representation of the y dose to a " maximum exposed individual." Some.of the factors used in L these calculations (such as ingestion rates) are maximum values.
Many of these factors are obtained from NUREG/CR-1004. The values chosen will tend to-overestimate the dose to this " maximum" person.
In reality, the 1.

. expected dose to actual individuals is lower. The calculation methods and results of the calculations are presented in the
_following sections.
DOSES FROM AIRBORNE EFFLUENTS
.For airborne effluents, the public can be_ exposed to radiation from several sources:
direct radiation from the radioactivity in the air, direct radiation from radioactivity deposited on the ground, inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited _from the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation which is then eaten by milk and beef animals.
The concentrations of radioactivity in the air and the soil are estimated by the computer model GELC which uses the actual meteorological conditions to determine the distribution of the effluents in the atmosphere. Again, as'many of the parameters-as possible are based on actual-site specific data. The model that is
- used to estimate dose, as well as the parameters input to the model,- ,
is described in detail in Section 1.0 of the Sequoyah Nuclear. Plant Offsite Dose Calculation Manual.
-m , c: Airborne Release Points and Meteorological Data Meteorological data at Sequoyah are measured continuously.
Measurements collected include the wind speed, wind direction, and
.the temperature at heights of 10, 46 and 91 meters above the ground. Average quarterly joint-frequency distributions (JFDs) are calculated for each release point using the appropriate levels of meteorological data. A joint frequency distribution gives the percentage of the time in a quarter that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a given stability class A through G. The wind speeds are
)> divided into nine wind speed ranges. For calculational purposes, calms are distributed into the lowest windspeed range (0-0.5 mph) according to the directional probabilities in the 0.6-1.4 mph range. Stability classes are determined from the vertical temperature gradient between two measurement levels.

SQN R d Imp;ct Jan-Dec 1989 page 5 of 41 q All' releases from'Sequoyah are considered ground-level releases to J
determine the dispersion of the airborne effluents. The ground-level JFD is derived from windspeeds and directions measured !
10 meters above ground and from the vertical temperature gradient i between 10 and 46 meters.
The JFDs for each quarter of 1989 are listed in Tables 3, 4, 5 and 6.
External Exposure Dose - Airborne Ef fluents Dose estimates for maximum externel air exposures (gamma-air and beta-air doses) are made for points ut and beyond the site -
boundary. These doses are calculated based on'the reported releases for all noble gas nuclides as shown on Table 1. The reported dose fis chosen for the offsite location with the highest calculated exposure during the quarter.

f . Internal doses to organs due to releases of airborne effluents are estimated for the inhalation, ground contamination, and ingestion pathways. 'The ingestion pathway is further divided into four possible contributing pathways: ingestion of cow / goat milk, ingestion of beef, and ingestion of vegetables. Doses from applicable pathways are calculated for each real receptor location defined in Table 7. Doses are calculated based on the reported iodine and particulate releases as shown on ,
! Table 1. To determine the maximum organ dose, the dose contribution from >
the three pathways are summed for'each receptor. For the ingestion dose, however, only those pathways that exist for each receptor are considered. .
in the sum, i.e., milk ingestion doses are included only for farms where i
!c milk is consumed without-commercial preparation and vegetable ingestion '
is included only for those locations where a garden is identified. To conservatively account for beef-ingestion, a beef ingestion dose equal to that for the highest site boundary location is added to each identified receptor. For ground contamination, the dose added to the organ dose i being calculated is the total body dose calculated for that location, N ti.e., it.is assumed that the' dose to an individual. organ is equal to the i
total body dose. The organ doses calculated for Sequoyah Nuclear Plant for each quarter in 1989 are shown below.

the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure f rom radioactive material deposited in the river sediment (recreation).
Th'e concentrations of radioactivity in the Tennessee River are estimated by a computer model which uses measured hydraulic data downstream of.Sequoyah. Parameters used to determine the doses are based on guidance given by the ARC (in Regulatory Guides.l.109) for-maximum ingestion rates, exposure times, etc. Wherever possible, parameters used in the dose calculation are site specific use factors determined:by TVA. The models that are used to estimate
~
doses, as well as the parameters input to the models, are described in Section 2.0 of the Sequoyah Nuclear Plant Offsite Dose Calculation Manual.
Liquid Release Points and River Data Radioactivity concentrations in the Tennessee River are calculated assuming-that releases of liquid effluents are. continuous. All 'i routine liquid releases from Sequoyah are made through diffusers- '
which extend into the Tennessee River. It is assumed that releases-to the river through these diffusers will initially be entrained in one-fifth of the water which flows past the plant. The'QWATA code makes the assumption that this. mixing condition' holds true until the'
< water is completely mixed- at' the first downstream dam, at Tennessee River mile 471.0. The average river flows.past the plant site were 43~962 ft /s for the first quarter of 1989, 38,557 ft'/s for the 3
3 second quarter of 1989, 42,756 ft /s for the third quarter of 1989 3
and 57,656 ft /s for the fourth quarter.

Doses are calculated for recreation, consumption of fish, and drinking water for locations between the plant site and the mouth of the Tennessee River._ The maximum potential recreation dose is calculated for a location immediately downstream from the plant outfall. The maximum individual dose from ingestion of fish is assumed to;be that calculated for the consumption of fish caught anywhere between the-plant and the first downstream dam (Chickamauga Dam). The maximum individual dose from drinking water is assumed to be that calculated at the nearest downstream public water supply (C. F. Industries). This could be interpreted as indicating that the maximum individual, as assumed for liquid releases from Sequoyah, is an~ individual who obtains all of his drinking water at C. F. Industries, consumes 21 kg (6.9 kg for a child) per year of fish caught from the Tennessee River between Sequoyah and Chickamauga Dam, and spends 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per year standing on the l shoreline just below the outfall from Sequoyah.

External. gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployed around SQN. During the preoperational e period from August 1975 to January 1980, these levels averaged approximately 23 mR/ quarter at onsite stations and 19 mR/ quarter offsite. These higher values measured onsite may be attributable to natural variations in environmental radiation levels, earth moving activitics onsite, the mass of concrete employed in the' construction of the plants, or other undetermined-influences.
Analysis of environmental TLD data for the period of November 1988 I to November 1989 showed that. the quarterly gamma radiation levels determinad from'these TLDs during this reporting period averaged ,
-approximately 17.2 mR/ quarter at onsite stations and approximately
.15.2 mR/ quarter at offsite stations. This is consistent with levels reported at TVA's nonoperating nuclear power plant construction sites where the average radiation levels onsite are generally ,
2-5 mR/ quarter higher than the levels offsite. Fluctuations in- d natural' background dose rates and in TLD readings tend to mask any small increments which may be due to plant operations. Thus, there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents. ;
DOSE TO MEMBERS OF THE PUBLIC INSIDE THE SITE BOUNDARY 3
No routine activities within the site boundary by members of the public have been identified which would lead to their radiation exposure.

To' determine compliance with 40 CFR 190, annual total dose contributions to the maximum individual from SQN radioactive effluents and all other nearby uranium fuel cycle sources are considered.
The annual total body dose to the maximum individual is conservatively estimated by summing the following doses:
