SUMMARY

The semiannual Effluent and Waste Disposal Report is a detailed listing of all radioactive releases (both gaseous and liquid) and the resulting radiation dose from the Davis-Besse Nuclear Power Station from January 1 through June 30,1988. A detailed Meteorological section provides the weather history of the area during the releases. This information is used to calculate the dose to the public. This report g also includes a summary of the amounts of radioactive material contained in solid waste packaged and shipped for offsite disposal at federally approved sites.

Basically, all the radioactivity of an operating nuclear power plant is contained within the plant itself. However, during normal operations, small amounts of g radioactive material are generated in gaseous and liquid wastes. The waste treat-ment systems at Davis Besse are designed to collect and process these wastes which contain radioactive material. The plant's radioactive waste systems provide for the storage, cleanup, and recycling of wastes. For example, the Waste Gas Decay Tanks are holding tanks which allow the radioactivity in gas to e decay be. fore releasing it to the stat:on vent and the environment.

The U.S. Nuclear Regulatory Commission reamres nuclear power stations be designed, constructed, and operated to keep the amount of radioactive material in effluent releases to unrestricted areas as low as reasonably achievable g (ALARA). To assure these criteria are met, the NRC has established limits governing the release of radioactivity in effluents. Davis-Besse has also estab-lished limits, which are well below the NRC limits, to ensure that radioactive ef-fluents are being maintaine.d ALARA.

The maximum radiation dose delivered to the inhabitants of the area around Davis-Besse, due to radioactivity released from the station, is very small. The radiation dose to people in the area is calculated for each release using the con-centration of radioactive material and the weather conditions at the time of the release. ,

A review of the effluent monitoring data from 1977 through 1988 shows that controlled liquid and gaseous releases, res'ulting from normal operations and ac-tivities at Davis-Besse, were well below the federal release limits and the maxi-O mum dose was a small fraction of the regulatory exposure limit.

.O INTRODUCIION O

Davis-sesse is designed and operated to strictly control the release of radioac-tivity to the environment in accordance with Nuclear Regulatory Commission (NRC) regulations. This Semiannual Radioactive Effluent and Waste Disposal Report provides the following information:

~O . Summation of the quantities of radioactive material (in the form of gases and liquids) released from the plant.

Summation of the quantities of radioactive material cop:2ined in solid waste packaged and shipped for offsite disposal at fer% rally approved sites.

O e Changes-to the Process Control Program (PCP).

e Changes to the Offsite Dcse Calculation Manual (ODCM).

In the reporting period, January 1 through June 30,1988, the total gaseous and liquid effluent releases were maintained as low as reasonably achievable O (ALARA). There were no changes to the PCP or the ODCM in this reporting period.

Sources O Through the normal operation of a nuclear power plant, most of the fission products are retained within the fuel and fuel cladding. However, small amounts of radioactive fission products migrate into the primary coolant. Additionally, trace amounts of the component and structure surfaces, which have been ac-tivated, also get into this water. Many of these particles are removed through O

demineralizers in a processing system. Small releases of radioactive liquids may occur from valves, piping or equipment associated with the primary coolant sys-tem. These liquids are collected through a series of floor and equipment drains and sumps. Allliquids of this nature are processed and carefully monitored prior to release.

D, l Noble gas fission products, which are not very soluble and cannot be removed by demineralizers, are given off as a gas when the primary coolant is depres.

Protection Standards e<l Soon after the discovery of X-rays in 1895 by Wilhelm Roentgen, the potential hazards of ionizing radiation were recognized and efforts were made to establish radiation protection standards.

The International Commission on Radiologicnt Protection (ICRP) was estab- e lished in 1928. In 1929, the National Council on Radiation Protection and Measurements (NCRP) was formed. These :wo groups have the longest con-tinuous experience in the review of radiation health effects and have established recommendations for radiological protection and radiation exposure limits.

W These organizations and many others are dedicated to understanding the health effects of radiation by investigating all sources of relevant information and by providing guidance for radiological ig ,

O Davis-Besse Nuclear Power Station Jan.- June,1988 The Semlannual Report Processing and Monitoring Effluents are strictly controlled to ensure radioactivity released to the environ-ment is minimal and does not exceed release limits. Effluent control includes the operation of radiation measuring systems, in-plant and offsite environmental sampling and analysis programs, quality assurance programs for effluents and en-1 vironmental samples, and procedures covering all aspects of effluent and environ-mental monitoring.

l The waste treatment systems at Davis-Besse are designed to collect and process !

the wastes which contain radioactive material. The plant's radioactive waste sys- #l tems provide for the storage, cleanup, and recycling of liquid and gaseous wastes. !

For example, the Waste Gas Decay Tanks are holding tanks which allow gaseous i radioactivity to decay prior to release to the station vent. Wastes are sampled prior to release and are reprocessed,if required.

O, Radioactivity monitoring systems are used to ensure radioactive material released is below regulatory limits. The instruments provide a continuous in-dication of radioactivity, and are sensitive enough to measure 100 to 1000 times lower than the release limits. Each instrument is equipped with alarms which indicate in the Control Rcom. The alarm set points are set low to ensure ef- G tiuent release limits will not be exceeded. If a monitor alarms, the release is automatically stopped.

nal or external depending on whether the source of radiation is within or outside the body.

Noble Gas O

Some of the radionuclides released in airborne effluents are radioactive isotopes of noble gases, such as xenon and krypton. Noble gases are biologically and chemically nonreactive. They do not concentrate in humans or other or-ganisms. They contribute to human radiation exposure by being a source of ex-ternal whole body exposure. Xenon-133 and xenon-135, with half-lives of g approximately 5 days and 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months , respectively, are the major noble gases released. They are readily dispersed in the atmosphere. Smaller amounts of krypton 85 (10.8 year half-life) are also released. The longer half-life of this radionuclide makes it more persistent in the atmosphere. However, nuclear power production is only a small contributor to the total atmospheric inventory ,

( of krypton-85 and has not caused measurable increases in background concentra-tions. During the operation of Davis-Besse (1977 through the present), the maxi-mum amount of noble gas released was 1012 curies in 1981. This was well below federal effluent limits. For January 1 through June 30,1988, approximately 107 <

curies of noble gases were released, whkh represents 0.03% of the gamma and g beta dose limit, i

lodine and Part!culates 9 Annual releases of radioactNe iodines and particulates in airborne and liquid effluents are small. Factors such as their high chemi:al reactivity and solubility in water, combined with the high efficiency of atrborne and liquid processing cys-

)

tems, minimize the discharge of radioactive iodines and particulates. Iodine-131 (8 day ha'.f-life)is the predominant radiciodine released. 8 The principal particulates released are radioactive cesiums (Cs-134 and Cs-137) and activation products (cobalt-58 and cobalt-60). The maximum amount of iodines and particulates released from Davis-Besse in a year was 0.054 curie in airborne effluents and 1.33 curies in liquid effluents, both in 1981. For January 9 1 through June 30,1988, the amount of radioactive lodines and particulates (without tritium) released was approximately 0.0006 curie in gaseous effluents and 0.01 curie in liquid effluents. These releases were well below federal ef-fluent limits.

9 9 e

)

i Davis-Besse Nuclear Power Station Jan.- June 1988 The Semlannual Report h Tritium Tritium, a radioactive isotope of hydrogen, is the predominant radionuclide in liquid effluents and also is present in gaseous effluents. Tritium is produced in reactor coolant as a result of neutron interaction with naturally occurring h deuterium (also a hydrogen isotope) present in water and with the boron used for reactivity control of the reactor. The maximur.1 amount of tritium released from Davis-Besse in a year was 1pproximately 36 curies in airborne effluents in 1982 and 246 curies in liquid effluents in 1987. The amount of tritium released

, was 43.9 curies in gaseous effluents and 26 curies in liquid effluents in January

) through June,1988. This is less than 1 percent of the federallimits. All releases of tritium (1977 to the present) have been substantially below the federal limits.

Since tritium is a low energy beta emitter and therefore of low dose conse-quence, the radioactivity concentration guide issued by the ICRP, NCRP, and other standard setting organizations is higher for tritium than for most other

) radionuclides. Because of the large abundance of tritium already in the environ-ment, much larger releases of tritium than possible from nuclear power genera-tien would be necessary to make a measurable change in environmental tritium concentrations.

)

Exposure Pathways Radiological exposure pathways are the methods by which people may become exposed to radioactivity released from nuclear facilities. The major pathways of concern are those which could cause the highest calculated radiation dose.

) These pathways are determined from the type and amount of radioactivity released, the environmental transport mechanism, and use of the environment.

The types and amounts of radioactivity released are carefully measured at Davis-Besse. The environmental transport mechanism includes consideration of physi-cal factors, such as the hydrological (water) and meteorological (weather)

) characteristics of the area. This provides information on the water flow, wind speed and wind direction at the time of the release.This information is used to evaluate how the radionuclides will be distributed in the area.The most impor-tant factor in evaluating the exposure pathways is the use of the environment.

Many factors are considered such as dietary intake of residents, recreational use,

) and the location of homes in the area.

The environmental pathways considered are shown in Figures 9 and 10. The radioactive gaseous effluent exposure pathways include direct radiation, deposi-tion on plants, deposition on soil, inhalation by animals and inhalation by humans. The radioactive liquid effluent exposure pathways include drinking i

10

l The Semlannual Report Jan.- June 1988 Davir-Besso Nuclear Power Station water, fish consumption and direct exposure from the lake, both shoreline and 9 immersion in the lake (swimming).

Although radionuclides can reach humans by many different pathways, some are more important than others. The pathway of concern is termed the critical pathway. De critical pathway is the exposure pathway which will provide, for a #

specific radionuclide, the greatest dose to a population, or to a specific group of the population. This group is called the critical group, and may differ depending on the radionuclides involved, age, diet, or other cultural factors. The dose may be delivered to the whole body or to a specific organ. The organ receiving the greatest fraction of the dose is called the critical organ. e l

Dose Assessment Dose is the energy deposited by radiation in an exposed individual. Whole body radiation involves the exposure of all organs. Most background exposures are of this form. Radioactive elements can enter the body through inhalation or ingestion. When they do, they are usually not distributed evenly. For example, radioactive iodine selectively concentrates in the thyroid gland, while radioactive

) cesium collects in muscle and liver tissue and radioactive strontium in mineral-ized bone.

dose of any ionizing radiation that produces the same biological effects as a unit of absorbed dose of x-rays. Often a e smaller unit of the rem, a millirem (mrem) is used. Milli- is a prefix used to denote 1/1000, so 1 millirem is equal to 1/1000 rem or 1000 millirems are equal to 1 rem. Generally, the term person-rem or man-rem is used to report the total dose to a population. If a population of 10,000 people each received 1 rem, the total dose to the population would be reported as 10,000 person-rem. e The radiation dose to peopic in the area surrounding Davis-Besse is calculated for each release using the concentrations of radioactive material and the weather conditions present at the time of release. The dose is calculated in the predominant wind direction and takes into account the location of the nearest 3:

residents, vegetable gardens, and milk animals. The dose calculated also uses the concepts of a "maximum exposed individual" and "standard man," and maxi-mum us.: factors for the environment. These are factors such as how much milk a person drinks per year, how long a person stays outdoms, and how much air a 8-In 1988 (January through June), the maximum individual offsite doses Jue to effluent releases were approximately:

These doses are only a small fraction of the limits for the most exposed mem-ber of the public. The highest dose was 0.08 mrem to the liver from liquid ef-

) fluents. This is only 0.3% of the limits specified in 40 CFR 190. By means of comparison, flying in a plane from New York to Los Angeles and back would cause a dose of about 2 mrem, and watching color TV causes a dose of about 1 mrem each year.

and chemically nonreactive; isotopes of these nuclides cause external radiation exposure. Particulate radioactivity with a half-life greater than 8 days is the major contributor to internal dose.

During the first quarter of 1988,106 curies of noble gas and 1.3 curies of iodine-131, tritium and particulates with half-lives greater than 8 days were released in the gaseous effluents. During the second quarter the amounts released were 1.3 curies and 42.6 curies respectively. The resulting dose from these amounts is only a small percentage (less than 0.2%) of the Davis Besse Technical Specifica-tions limits (See Table 1). Section 7 of Appendix A and Tables 1-3 of Appendix 8

B give more details on gaseous effluents.

Liquid Effluents Radioactivity in liquid effluents consists of radioactive fission and activation ,

products, tritium, and entrained radioactive gases. During the first quarter ap-proximateiy 0.005 curie of fission and activation products,22.6 curies of tritium, and 0.124 curie of dissolved and entrained gases were released. During the second quarter the amounts released were 0.007 curie,3.06 curies and 0.00001 curie respectively.The resulting dose from this radioactivity was well below the ,.

O 1 Solid Waste Shipments In order to reduce the radiation exposure to personnel and maintain the ALARA concept, the NRC and the Depa tment of Transportation (DOT) have j O established limits on the types of radioactive waste and the amount of radioac- l tivity that may be packaged and shipped offsite for burial or disposal. To ensure that Davis-Besse is complying with these regulations, the types of waste and the radioactivity present are reported to the NRC For the six month period of January 1 through June 30,1988, no radioactive wastes were shipped offsite. j O

There have been no shipments ofirradiated fuel for January through June,1988.

.- g RESULTS De results of the liquid and gaseous effluent monitoring program are reported semiannually to the NRC. For January 1 through June 30,1938, the doses (whole body and organ) from radioactive releases were a small fraction of the NRC limits. The dose due to liquid releases was less than 0.3 percent of the NRC limits and the dose due to gaseous releases was even smaller,less than 0.03 ,

percent of the NRClimits.

A review of effluent monitoring data from 1977 through 1988 shows that con-trolled liquid and gaseous releases resulting from normal operations and ac-tivities at Davis-Besse did not exceed federal relcase limits and the maximum 8 dose was a small fraction of the regulatory exposure limit (Fig. I and 2).

In special instances, menbers of the public are permitted access to the radiologically controlled area within the Davis-Besse station.

()

i The Visitor Center located inside the Davis-Besse Administration Building (DBAB) l is also accessible to members of the public. Considering the frequency and <

duration of the visits, the resultant dose vould be a small fraction of the l C) calculated maximum site boundary dose. The dose from gaseous effluents as 1 modeled for the DBAB Visitor Center is considered the controlling factor when evaluating doses to members of the pc511c from activities inside the site boundary. For purposes of assessing the dose to members of the public in accordarce with Technical Specification 6.9.1.11, the following exposure assump'. ions may be used:

O

- Exposure time for maximum exposed visitor of 20 hours2.314815e-4 days 0.00556 hours 3.306878e-5 weeks 7.61e-6 months (4 v! sits, 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months per visit).*

- Annual average meteorological dispersion (conservative, default use of maximum site boundary dispersion).

O The equations in the ODCM may be used for calculating the potential dose to a member of the public for activities inside the site boundary. Based on these assumptions, this dose vould be at least a factor of 400 less than the maximum !

site boundary air dose as calculated in the ODCH. ,

() There are no areas onsite accessible to the public where exposure to liquid effluents could occur. Therefore, the modeling of the ODCM conservatively estimates the maximum potential dose to members of the public.

Heteorological Monitoring Heteorological data collected onsite for the period of January 1, 1988 through

) June 30, 1988 vere reduced, validated, summarized for analysis, and included in the appropriate dose calculations. The Meteorological Honitoring System is instrumented for vind speed, vind direction, and temperature at 340 feet, 250 feet and 35 feet. Dev point temperatures are measured at 340 and 35 feet.

Precipitation is gathered at ground level. In addition, differential temperatures (Delta T) are measured betveen 340 to 35 fee.t and 250 to 35 feet.

) Delta T's are classified into Pasquill stability classifications using the following table.

SUMMARY

The Semiannual Effluent and Waste Disposal Report is a detailed listing of all radioactive releases (both gaseous and liquid) and the resulting radiation dose from the Davis-Besse Nuclear Power Station from January 1 through June 30,1988. A detailed Meteorological section provides the weather history of the area during the releases. This information is used to calculate the dose to the public. This report ,

also includes a summary of the amounts of radioactive material contained in solid waste packaged and shipped for offsite disposal at federally approved sites.

Basically, all the radioactivity of an operating nuclear power plant is contained within the plant itself. However, during normal operations, small amounts of ,

radioactive material are generated in gaseous and liquid wastes. The waste treat-ment systems at Davis-Besse are designed to collect and process these wastes which contain radioactive material. The plant's radioactive waste systems provide for the storage, cleanup, and recycling of wastes. For example, the Waste Gas Decay Tanks are holding tanks which allow the radioactivity in gas to decay before releasing it to the station vent and the environment.

De U.S. Nuclear Regulatory Commission requires nuclear power stations be designed, constructed, and operated to keep the amount of radioactive material in effluent releases to unrestricted areas as low as reasonably achievable (ALARA). To assure these criteria are met, the NRC has established limits 8

, governing the release of radioactivity in effluents. Davis-Besse has also estab-l lished limits, which are well below the NRC limits, to ensure that radioactive ef-i fluents are being maintained ALARA.

l The maximum radiation dose delivered to the inhabitants of the area around 8

l Davis-Besse, due to radioactivity released from the station, is very small. The l radiation dose to people in the area is calculated for each release using the con-centration of radioactive material and the weather conditions at the time of the release.

Liquids: ~ 0.05 mrem, whole body 0.08 mrem, liver O These doses were only a small fraction of the limit for the most exposed mem-ber of the public. The highest dose was 0.08 mrem to the liver from liquid ef-fluents. This represents only 0.3% of the limit specified in 40 CFR 190. By means of comparison, flying in a plane from New York to Los Angeles and back would cause a dose of about 2 mrem, which is 25 times more than the highest O dose from liquid effluents at Davis-Besse.

A review of the effluent monitoring data from 1977 through 1988 shows that controlled liquid and gaseous releases, resulting from normal operations and ac-tivities at Davis-Besse, were well below the federal release limits and the maxi-O mum dose was a small fraction of the regulatory exposure limit.

Figures 1 and 2 present a comparison of the NRC guidelines and the results of monitoring effluents at Davis-Besse since 1978. These graphs show that Davis-Besse has maintained doses to the public far below the applicable regulatory O limits.

INTRODUCIION D

Davis.nesse is designed and operated to strictly control the release of radioac-tivity to the environment in accordance with Nuclear Regulatory Commission (NRC) regulations. This Semiannual Radioactive Effluent and Waste Disposal Report provides the following information:

J e Summation of the quantities of radioactive material (in the form of gases and liquids) released from the plant.

e Summetion of the quantities of radioactive material contained in solid waste packaged and shipped for offsite disposal at federally approved sites.

U e Changes to the Process Control Program (PCP).

Changes to the Offsite Dose Calculation Manual (ODCM).

In the reporting period, January 1 through June 30,1988, the total gaseous and liquid effluent releases were maintained as low as reasonably achievable 3 (ALARA). There were no changes to the PCP or the ODCM in this reporting period.

Sources 3 Through the normal operation of a nuclear power plant, most of the fission products are retained within the fuel and fuel cladding. However, small amounts of radioactive fission products migrate into the primary coolant. Additionally, trace amounts of the component and structure surfaces, which have been ac-tivated, also get into this water. Many of these particles are removed through

demineralizers in a processing system. Small releases of radioactive liquids may occur from valves, piping or equipment associated with the primary coolant sys-tein. These liquids are collected through a series of floor and equipment drains and sumps. Allliquids of this nature are processed and carefully monitored prior to release.

l Noble gas fission products, which are not very soluble and cannot be removed by demineralizers, are given off as a gas when the primary coolant is depres-l l

Protection Standards Soon after the discovery of X-rays in 1895 by Wilhelm Roentgen, the potential hazards of ionizing radiation were recognized and efforts were made to establish radiation protection standards.

The International Commission on Radiological Protection (ICRP) was estab- ,

lished in 1928. In 1929, the National Council on Radiation Protection and Measurements (NCRP) was formed. These two groups have the longest con-tinuous experience in the review of radiation health effects and have establisited recommendations for radiological protection and radiation exposure limits.

These organizations and many others are dedicated to understanding the health effects of radiation by investigating all sources of relevant information and by

_ providing guidance for radiological ge I } protection. The U.S. Nuclear

O Davis-Besse Nuclear Power Station Jan. June,1988 The Semlannual Report Processing and Monitoring Effluents are strictly controlled to ensure radioactivity released to the environ-ment is minimal and does not exceed release limits. Effluent control includes the operation of radiation measuring systems, in-plant and offsite environmental sampling und analysis programs, quality assurance programs for effluents and en-vironmental samples, and procedures covering all aspects of effluent and environ-mental monitoring.

The waste treatment systems at Davis-Besse are designed to collect and process the wastes which contain radioactive material. The plant's radioactive waste sys- #.

tems provide for the storage, cleanup, and recycling of liquid and gaseous wastes.

For example, the Waste Gas Decay Tanks are holding tanks which allow gaseous radioactivity to decay prior to release to the station vent. Wastes are sampled prior to release and are reprocessed,if required.

O Radioactivity monitoring systems are used to ensure radioactive material released is below regulatory limits. The instruments provide a continuous in-dication of radioactivity, and are sensitive enough to measure 100 to 1000 times lower than the release limits. Each instrument is equipped with alarms which l indicate in the Control Room. The alarm set points are set low to ensure ef- 9:

fluent release limits will not be exceeded. If a monitor alarms, the release is automatically stopped.

Noble Gas O

Some of the radionuclides released in airborne effluents are radioactive isotopes of noble gases, such as xenon and krypton. Noble gases are biologically and chemically nonreactive. They do not concentrate in humans or other or-ganisms. They contribute to human radiation exposure by being a source of ex-ternal whole body exposure. Xenon-133 and xenon-135, with half-lives of g approximately 5 days and 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months , respectively, are the major noble gases released. They are readily dispersed in the atmosphere. Smaller amounts of krypton-85 (10.8 year half-life) are also released. The longer half-life of this radionuclide makes it more persistent in the atmosphere. However, nuclear power production is only a small contributor to the total atmospheric inventory ,

of krypton-85 and has not caused measurable increases in background concentra-tions. During the operation of Davis Besse (1977 through the present), the maxi-mum amount of noble gas released was 1012 curies in 1981. This was well below federal effluent limits. For January 1 through June 30,1988, approximately 107 curies of noble gases were released,which represents 0.03% of the gamma and ,;

beta dose limit.

lodine and Particulates ,

Annual releases of radioactive iodines and particulates in airborne and liquid effluents are small. Factors such as their high chemical reactivity and solubility in water, combined with the high efficiency of airborne and liquid processing rys-tems, minimize the discharge of radioactive iodines and particulates. Iodine-131 (8 day half-life) is the predominaut radioiodine released. 9 i

The principal particulates released are radioactive cesiums (Cs-134 and Cs-137) and activation products (cobalt-58 and cobalt-60). The maximum amount of iodines and particulates released from Davis-Besse in a year was 0.054 curie in airborne effluents and 1.33 curies in liquid effluents, both in 1981. For January 9 1 through June 30,1988, the amount of radioactive iodines and particulates (without tritium) released was approximately 0.0006 curie in gaseous effluents and 0.01 curie in liquid effluents. These releases were well below federal ef-fluent limits.

O ;

Davis-Besse Nuclear Power Station Jan.- June 1988 The Semlannual Report l O Tritium 1 Tritium, a radioactive isotope of hydrogen, is the predominant radionuclide in liquid effluents and also is present in gaseous effluents. Tritium is produced in reactor coolant as a result of neutron interaction with naturally occurring

O deuterium (also a hydrogen isotope) present in water and with the boron used for reactivity control of the reactor.The maximum amount of tritium released from Davis-Besse in a year was approximately 35 curies in airborne effluents in 1982 and 246 curies in liquid effluents in 1987. The amount of tritium released was 43.9 curies in gaseous effluents and 26 curies in liquid effluents in January O through June,1988. This is less than 1 percent of the federallimits. All releases of tritium (1977 to the present) have been substantially below the federallimits.

Since tritium is a low energy beta emitter and therefore of low dose conse-quence, the radioactivity concentration guide issued by the ICRP, NCRP, and other standard setting organizations is higher for tritium than for most other O radionuclides. Because of the large abundance of tritium already in the environ-ment, much larger releases of tritium than possible from nuclear power genera-tion would be necessary to make a measurable change in environmental tritium concentrations.

O Exposure Pathways Radiological exposure pathways are the methods by which people may become exposed to radioactivity released from nuclear facilities. The major pathways of concern are those which could cause the highest calculated radiation dose.

These pathways are determined from the type and amount of radioactivity released, the environmental transport mechanism, and use of the environment.

The types and amounts of radioactivity released are carefully measured at Davis-Besse. The environmental transport mechanism includes consideration of physi-Cal factors, such as the hydrological (water) and meteorological (weather) characteristics of the area. This provides information on the water flow, wind speed and wind direction at the time of the release.This information is used to evaluate how the radionuclides will be distributed in the area.The most impor- '

tant factor in evaluating the exposure pathways is the use of the environment.

Many factors are considered such as dietary intake of residents, recreational use,

.O and the location of homes in the area.

The environmental pathways considered are shown in Figures 9 and 10. The radioactive gaseous effluent exposure pathways include direct radiation, deposi-tion on plants, deposition on soil, inhalation by animals and inhalation by

.O humans. The radioactive liquid effluent exposure pathways include drinking 10

O The Semlannual Report Jan. June 1988 Davis-Besse Nuclear Power Station water, f13h consumption and direct exposure from the lake, both shoreline and immersion in the lake (swimming).

Although radionuclides can reach humans by many different pathways, some are more important than others. The pathway of concern is termed the critical pathway. The critical pathway is the exposure pathway which will provide, for a specific radionuclide, the greatest dose to a population, or to a specific group of the population. This group is called the critical group, and may differ depending on the radionuclides involved, age, diet, or other cultural factors. The dose may be delivered to the whole body or to a specific organ. The organ receiving the greatest fraction of the dose is called the critical organ. 9

Dose Assessment O

Dose is the energy deposited by radiation in an exposed individual. Whole body radiation involves the exposure of all organs. Most background exposures are of this form. Radioactive elements can enter the body thiough inhalation or ingestion. When they do, they are usually not distributed evenly. For example,

'O radioactive iodine selectively concentrates in the thyroid gland, while radioactive cesium collects in muscle and liver tissue and radioactive strontium in mineral-ized bone.

dose to a population. If a population of 10,000 people each received 1 rem, the I total dose to the population would be reported as 10,000 person rem. g.

The radiation dose to people in the area surrounding Davis-Besse is calculated for each release using the concentrations of radioactive material and the weather conditions present at the time oirelease. The dose is calculated in the l predominant wind direction and takes into account the location of the nearest ,

residents, vegetable gardens, and milk animals. The dose calculated also uses the concepts of a "maximum exposed individual" and "standard man," and maxi-mum use factors for the environment. These are factors such as how much milk a person drinks per ye ar, how long a person stays outdoors, and how much air a ei l

In 1988 (January through June), the maximum individual offsite doses due to effluent releases were approximately: ;

During the first quarter of 1988,106 curies of noble gas and 1.3 curies of iodine-131, tritium and particulates with half lives greater than 8 days were released in the gaseous effluents. During the second quarter the amounts released were 1.3 curies and 42.6 curies respectively. The resulting dose from these amounts is only a small percentage (less than 0.2%) of the Davis-Besse Technical Specifica-tions limits (See Table 1). Section 7 of Appendix A and Tables 1-3 of Appendix B give more details on gaseous effluents.

products, tritium, and entrained radioactive gases. During the first quarter ap-proximately 0.005 curie of fission and activation products,22.6 curies of tritium, and 0.124 curie of dissolved and entrained gases were released.

4 RESULTS The results of the liquid and gaseous effluent monitoring program are reported semiannually to the NRC. For January 1 through June 30,1988, the doses (whole body and organ) from radioactive releases were a small fraction of the NRC limits. The dose due to liquid releases was less than 0.3 percent of the NRC limits and the dose due to gaseous releases was even smaller, less than 0.03 O

percent of the NRClimits.

A review of effluent monitoring data from 1977 through 1988 shows that con-trolled liquid and gaseous releases rr.;ulting from normal operations and ac-tivities at Davis-Besse did not exceed federal release limits and the maximum dose was a small fraction of the regulatory exposure limit (Fig.1 and 2).

The Visitor Center located inside the Davis-Besse Administration Building (DBAB) is also accessible to members of the public. Considering the frequency and duration of the visits, the resultant dose vould be a small fraction of the calculated maximum site boundary dose. The dose from gaseous effluents as

() modeled for the DBAB Visitor Center is considered the controlling factor when evaluating doses to members of the public from activities inside the site beundary. For purposes of assessing the dose to members of the public in accordance with Technical Specification 6.9.1.11, tha following exposure assumptions may be used:

C)

- Exposure time for maximum exposed visitor of 20 hours2.314815e-4 days 0.00556 hours 3.306878e-5 weeks 7.61e-6 months (4 visits, 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months per visit).*

- Annual average meteorological dispersion (conservative, default use of maximum site boundary dispersion).

O The equations in the ODCH may be used for calculating the potential dose to a member of the public for activities inside the site boundary. Based on these assumptions, this dose vould be at least a factor of 400 less than the maximum site boundary air dose 3s calculated in the ODCM.

, () There are no areas onsite accessible to the public where exposure to liquid effluents could occur. Therefore, the modeling of the ODCM conservatively estimates the maximum potential dose to members of the public.
