EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION SECOND HALF 1987 II. Maximum Permissible Concentrations A. Fission and Activation Gases in Gaseous Effluent

1. The instantaneous release rate of fission and activation gases is regulated by the dose rate limit of 10CFR20 Appendix B. The dose rate at, any time to areas at and beyond the site boundary due to noble gases released in gaseous effluents from the site shall be limited to < 500 mrem/year to the total body and < 3000 mrem/year to the skin.

2. The BFN Offsite Dose Calculation Manual (ODCM) determines the maximum noble gas release rate based upon the dose rate limits in II.A.l. The instantaneous noble gas release rates are limited by the following equation:

Ql + 92 X 1 0.15 14.4 Ql = The release h rate from the building exhaust vents in Ci/sec.

Q2 = The release rate from the main stack in Ci/sec.

B and C. Iodines and Particulates with Half Lives Greater than 8 Days in Gaseous Effluents

1. The instantaneous release rate of particulates and iodines is regulated by the dose rate limit of 10CFR20 Appendix B. The dose rate at any time to areas at and beyond the site boundary due to I-131, I-133, H-3 and particulates with greater than eight days half-lives released in gaseous effluents from the site shall be limited to <1500 mrem/yr to any organ.

2. The BFN ODCM determines the maximum particulate and iodine release rate based upon the dose rate limit of II. B and C.l. The instantaneous iodine and particulate release rates are limited by the following equation:

+ g4 gl 2.19 35.7 Q3 = The release rate from the building exhaust vents in mCi/sec Q4 = The release rate from the main stack in mCi/sec.

EFFLUENT AND HASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION SECOND HALF 1987 D. Liquid Effluents

1. The concentration of radionuclides in liquid effluents released at any time from the site to unrestricted areas shall be limited to the concentrations specified in 10CFR 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases.

2. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 mCi/ml total activity.

III. Average Energy Not applicable IV. Measurements and A roximations'of Total Radioactivit A. Fission and Activation Gases:

1. Noble gases in the building vent and stack, gaseous effluent are continuously monitored. The flow rate of the stack is continuously monitored- and the building vent effluent flow rates are calculated once a shift based on the configuration of operating exhaust fans. The flow rate data is consolidated weekly to determine the volume of airborne effluent released from the plant. The noble gas monitor data is consolidated monthly to determine the total curies of noble gases released during the month.

2. Gas grab samples are taken and analyzed monthly to determine the relative noble gas activity concentrations. This information is used to apportion the total curies of noble gases released between different noble gas radionuclides.

3. The tritium concentration is determined by the analysis of a monthly grab sample for each release point.

B and C. Iodines and Particulates

1. Iodines and particulates are continuously sampled on impregnated charcoal filters and particulate filters, respectively. The charcoal and particulate samples are replaced at least weekly and analyzed to determine specific activity concentrations. The specific activity concentrations and vent flow rate data are used weekly to verify that release rate limits were not exceeded. The specific activity concentrations and total volume of gaseous effluent are used on a monthly basis to determine the total curies of each particulate and iodine released during the month.

EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION SECOND HALF 1987 IV. Measurements and A roximatio s of Total Radioactivit (Continued)

2. The gross alpha concentration is determined by analysis of a monthly particulate filter composite sample and strontium -89 and

-90 are determined by analysis of a quarterly particulate filter composite sample for each release point.

D. Liquid Effluents

1. The gamma ray emitting radionuclide concentrations are determined " .

for each batch by gamma ray spectroscopy analysis of a grab sample. The allowable release rate is calculated for each batch based upon the known dilution flow... The flow rate of the liquid effluent is continuously monitored and the total volume released in each batch is determined. The total gamma activity released in each batch is determined by multiplying the radionuclide concentrations by the total volume discharged. The total gamma activity released during the month is then determined by summing the gamma activity content of each batch discharged during the month.

2. The gross alpha and tritium concentrations are measured on a monthly composite sample. The strontium -89 and -90 and iron -55 are measured on a quarterly composite sample.

Radiological Impact Assessment Browns Ferry Nuclear Plant July December 1987 Introduction potential doses to individuals and populations have been calculated for the time period July through December in compliance with the requirements of Radiological Effluent Technical Specification 6.7.3.A. Dose calculations are based on Regulatory Guides 1.109, 1.111, 1.113, and NUREG/CR-1004 to determine compliance with the dose objectives contained in 10 CFR 50, Appendix I, and 40 CFR 190. Measured plant releases (listed in tables 1-3 for radioactivity in both gaseous and liquid effluents) for the reporting period are used as input in the Gaseous Effluent Licensing Code (for gaseous releases) and the Quarterly Mater Assessment Code (for liquid releases) to estimate dose. Dispersion of radioactive effluents in the environment has been calculated using meteorological data and riverflow data measured during this period.

Meteorolo ical Data Meteorological data were measured, and average quarterly joint frequency distributions (JFDs) for ground-level, split-level, and stack 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 ground-level portion of the split-level JFD was based on wind speeds and directions measured with a sensor located 10 meters above ground-level and from the vertical temperature gradient between 10 and 45 meters. The elevated portion of the split-level JFD was based on wind speeds and direction measurements at the 46-meter level and the vertical temperature gradient between 45 and 90 meters. The JFDs for elevated releases were based on wind directions and wind speeds measured at 93 meters. Stability class D was assumed to persist at the effluent release level of 180 meters for the entire period. For the period January 1, 1978 December 31, 1980, stable conditions (E, F, or G stability) existed in the layer from 45 to 90 meters at Browns Ferry Nuclear Plant (BFH) about 43 percent of the time. Neutral conditions existed about 56 percent of the time. This suggests that the use of a D stability for stack releases is conservative or realistic about 99 percent of the time. Also, temperature data taken between 110 and 275 meters at the Colbert Steam Plant during the spring and summer of 1976 indicated that for that layer stable conditions existed 53 percent of the time and neutral conditions existed 45 percent of the time. Thus, the 98 percent occurrence of stable or neutral conditions in the elevated layer at Colbert is comparable to the BFN upper layer percent. Although these data are limited to spring and summer, the small percentage of unstable conditions in the 3-year data set suggests that the results are reasonable throughout the year. For an elevated release, assumption of class D instead of E yields conservative results.

(0300c)

The wind speeds were divided into nine wind speed ranges. Calms (0-0.5 mph) were not distributed by direction. The quarterly JFDs are listed in tables 4 and 5 for ground-level releases, tables 6 and 7 for split-level releases, and in tables 8 and 9 for elevated releases.

Gaseous Effluents Ground-level and elevated dispersion models were applied to turbine building and stack releases respectively. Releases from the reactor building and radwaste building were treated as split-level releases, i.e.,

partly elevated and partly ground-level. The split-level dispersion approach was implemented using a model that required for each effluent vent two complete average-annual JFDs, one for the elevated releases and one for the ground-level releases. Radionuclides in gaseous effluents were assumed to be released continuously. The generally open terrain around BFN is not believed to cause any significant effects on the transport and dispersion of gaseous effluents from the plant. Within 30 kilometers of BFN, the terrain is. mostly gently rolling hills (30-60 meters). Between 30 and 80 kilometers the .hills become larger to the north and south, and mountainous to the east and northeast. Terrain may have a small effect on transport and dispersion during-periods of southeasterly and southerly winds, overcast skies, and relatively high wind speeds. Then, the lower layer (10-45 meters) tends to be more stable than would be expected. However, during this infrequent condition, dose estimates will be conservative.--

Dose estimates for external air exposures were made at and beyond the site boundary. External doses to the skin and total body were estimated for the nearest residence in each sector. Internal doses to organs were estimated from the ingestion, inhalation, and ground contamination exposure pathways. The internal doses were calculated for farms where milk is consumed without commercial preparation. All receptor locations and points of interest are listed in table 3a. Doses are given in tables 10 and ll locations.

for these individual exposure pathways at the maximum exposure Population doses were calculated for an estimated 627,000 persons living within a 50-mile radius of the plant site. Population doses were calculated assuming that each individual consumes vegetables and meat produced with the sector annulus in which he resides. Doses'rom milk ingestion were calculated 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 12.

Li uid Effluents Doses from liquid effluents were calculated using measured hydraulic data. The average river flows at the plant site were 25,380 ft3/s for the third quarter and 20,462 ft3/s for the fourth quarter.

Radioactivity concentrations in the Tennessee River were calculated assuming that releases in liquid effluents were continuous.

(0300c)

Doses were calculated for recreation, consumption of fish, and drinking water from public water supplies between the plant site and the mouth nf the Tennessee River. The maximum individual dose from drinking, water was assumed to be that calculated at the nearest downstream public water supply (Champion paper Company). 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 13 and 14.

Direct Radiation External gamma radiation levels. were measured by thermoluminescent dosimeters (TLDs) deployed around BFH. The quarterly gamma radiation levels determined from these TLDs during this reporting period averaged approximately 20.2, mR/quarter at onsite stations and approximately 17.0 mR/quarter at offsite stations, or approximately 3.2 mR/quarter higher onsite than 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 2-6 mR/quarter higher than the levels offsite. This may be attributable to natural variations in environmental radiation levels, earth moving, activities onsite, the mass of concrete employed in the, construction of the plants, or other undetermined influences. 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 was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents.

Doses calculated for this semiannual period result from the low-level effluent releases of units 1, 2, and 3. For gaseous effluents released in the third quarter, the maximum ganja and beta air doses were calculated to be <.001 and <.001 mrad, respectively. During the fourth quarter, the ganef and beta air doses were <.001 and <.001 mrad, respectively. These quarterly doses are well below the annual air dose guidelines (as specified in Appendix I to 10 CFR 50) of 30 and 60 mrad for ganana and beta radiation, respectively, for three reactor units. The maximum doses from noble gases to the skin and total body during the third quarter were calculated to be 0.0 and 0.0 mrem. During the fourth quarter, the skin and total body doses were <0.001 and <0.001 mrem respectively. The dose to the maximum exposed organ was 0.0037 mrem to the g.i. tract for the third quarter and 0.0071 mrem to the liver for the fourth quarter. These can be compared with annual dose guidelines of 45 mrem to the skin and maximum exposed organ and 15 mrem to the total body. These doses result from ingestion, inhalation, and ground contamination pathways and can be compared to a natural background radiation dose to an individual of about 90 mrem/yr.

For liquid effluents released in the third quarter, the maximum individual doses to the total body and the maximum exposed organ (i.e., liver) were calculated to be 0.055 and 0.073 mrem, respectively. In the fourth (0300G)

quarter, the maximum doses to the total body and liver were 0.089 and 0 12 mrem, r espectively. These compare with annual dose guidelines as specified I

in Appendix to 10 CFR 50 of 9 and 30 mrem to the total body and maximum exposed organ, respectively, for three units.

population doses from gaseous effluents during the third quarter were estimated to be 0.0025 man-rem to the g.i. tract and 0.0029 man-rem to the lung. For the fourth quarter, population doses were 0.0026 man-rem to the liver and 0.0022 man-rem to the bone.

From liquid releases during the. third quarter, the total population along the Tennessee River was estimated to receive 4.5 man-rem to the total body and 7.9 man-rem to the maximum exposed organ (liver). For the fourth quarter, the Tennessee .River population was estimated to receive 7.4 man-rem to the total body and 13 man-rem to the maximum exposed organ (liver).

population doses can be compared to the natural background dose to the 627,000 persons living within 50 miles of the plant of about 56,430 man-rem/yr.

To determine compliance with 40 CFR 190, the annual dose contributions to the maximum individual from BFN radioactive effluents and all other nearby uranium fuel-cycle sources have been considered. No nearby fuel-cycle facilities other than BFN 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 1987 has been calculated to be 0.52 mrem. This is well below the limit of 40 CFR 190 (25 mrem/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 determining plant performance a sunanary of the quarterly doses for the past five years is presented in Table 15. Figures 1 through 5 present this data graphically.

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 BFN Technical Specifications for plant operation.
