SUMMARY

_QI_L10VID_AND_0ASE0VS E YLUENT.,EELEASES m 1991 Although nuclear plants are designed to contain the radioactive material ,

created by the fleston process, small amounts of this material escape  :

from the fuel rods. Also, very small amounts of the structures and components of t.he systems becomo activated through the bombardment of neutrons and are_ worn away. This radioactive material can be transported  ;

throughout plant systems and released to the environment.

EIIlvent_MonAtorlns l Plant paths through which radlonctivity is released are monitored. These monitors record the radiation levels for each release. Monitors which  !

are used for liquid releases will automatically alarm and stop any ,

release which-la above regulatory-limits. Gaseous release monitors also provido alarming mechanisms to allow for the termination of any release above limits.

AltbgIne_Releasun -

The noble gas (16plon products do not mix with water and are glven off in a gaseous form. A very small amount of solid redlonctivity is given off along with-these noble gases. These_ releases are_ processed so that the radioactive materici la filtered and/or decayed prior to release through the plant vents.- Sampilng-and monitoring iethods are used Lo determine ,

the amount of radioactive material released. If these methods indicate that radioactivity-in airborne offluents above preset limits, then i releases _are. terminated. ,

SQN Rad Impset Jan-Dec 1991 Page 2 of 36 Liquid Feleones Some small amounts of radioactive material migrate Anto the primary coolant water. The primary coLlant water la 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 dominera11sers, to temove contaminants. The purifled water is then monitored to dete:mine the nmount 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 the levels of radioactivity are above preset limits, the releases are circulated through the clean-up system again for additional processing. All radioactivity released from the plant into the Tennessee River is quantitled prior to release.

D'JS A'_ LIMITS The U.S. Nuclent Regulator Commission (HRC) requires nuclear power plants to be designed, built, and operated in such a way that the 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 requirements for Controls which govern the release of radioactivity. These Controls, contained in the Sequoyah ODCM, specify limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of these effluents. These limits are set well below the NRC 10 CFR 20 limits which govern the concentrations of radioactivity and exposures permissible in unrestricted areas. This ensures that radioactive _

effluent releases are ALARA.

The ODCM 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.

DDSE_CALCULAT10FS Estimated doses to the public are determined using computer models (the Gaseous Effluent Licensing Code, GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models are based on guidance provided by the NRC (jn Regulatory Guides 3.109, ? ;'l 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 dose to a " maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maxiK2m 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 expected dose to actual individuals is lower. The 0017v

Again, as many of the parameters as

Airborne Releamg_2plnts atd 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

.meteorslogical data. A joint frequency distribution gives the perceslage of the cime 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 rango. Stability classes are determined from the vertical temperature gradient between two measurement levels.

LInternal doses to organs due to releases of airborne effluents are estimatec_'or the inhalation, ground contamination, and ingestion pathways._ The ingestion pathway is further divided into four possible contributing pathways ingestion of cow /guat milk, ingestion of beef, and ingestion of vegetables.- Doses from applicable pathways are calculated for each real receptor location defined in Table 5. Doses are calculated based on the reported iodine and particulate releases. 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 milk is consumed without commercial preparation and vegetable ingestion 2s 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 being calculated is the total body dose calculated for that location, i.e., it is assumed that the dose to an individual organ is equal to the total body dose.

The organ doses calculated for Sequoyah Nuclear Plant for each quarter in 1991 are shown below.

the ingestion of water from the Tennessee River, the ingestion of fish-caught in the Tennessee River, and direct exposure from radioactive material deposited in the river sedinant (recreation).

The concontrations of radioactivity in the Tennessee River are

-dstimated 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 NRC (in Regulatory Guides 1.109) for maximum ingestion rates, exposure times, etc. Wherever possible, parameters used in the dose calculation are site specific use j -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 6.0 of the Sequoyah Nuclear Plant Offsite Dose

_ Calculation Manual.

Ligyld Release Points and Rive.I_DALA 2

Radioactivity concentrations in the Tennessee River are calculated assuming that releases of liquid effluents are continuous. All 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 milo 471.0. The average river flows past the plant site were 57,536 ft 3 /s for the first quarter of 1991, 28,775 ft 3/s for the second quarter of 1991, 32,101 ft3 /s for the third quarter of 1991 and 45,329 ft 3 /s for the fourth quarter, l'

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 con- stion of fish caught anywhere between the plant and the first downstream dam (Chickamauga Dmn) . 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 11guld releases from Sequoyah, is an individual'who obtains all of his dr!nking water at C..F.

- DIRECT RADIAIIDH External gamma radiation levels were measured by thdrmoluminescent 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 higher values measured onsite may be attributable to natural variations in environmental radiation levels, earth moving activities onsite, the mar:s of concrete employed in the construction of the plants, or other undetermined influences.

Analysis of environmental TLD data for the period of November 1990 to November 1991 showed that the cuar'.erly gamma radiation levels determine 6 from these TLDs during this reporting period averaged approximately 14.4 mR/juarter at onsite stations and approximately

'12.6 mR/ quarter at offsite. stations. This is consistent with levelp 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 natural background. dose rates and in TLD readings. tend to mask any small increments which may be due to plant operations. Thus, there
