SUMMARY
REPORT I
- l. FOR 1997 l
1.0 INTRODUCTION
L
- This report summarizes the radiological dose conunitments resulting from all radioactive liquid -
and gaseous effluent discharges during the 1997 calendar year. The off-site doses presented by calendar quarter in Table I were determined from primary effluent data sets which have been summarized and reported to the NRC in the Annual Radioactive Effluent Release Report for 1997. Cumulative joint l: frequency distributions for wind speed, wind direction, and atmospheric stability for the 12-month period, January to December 1997, are provided in Tables A through H.' Annual wind roses are also provided in Figures 1 and 2.
- For the purposes of demonstrating conformance with -40CFR190, " Environmental Radiation l Protection Standards for Nuclear Power Operations," radiation dose estimates must include direct i
radiation ~ contributions from significant plant sources. Thermoluminescent dosimeters (TLDs) in the area of the western perimeter security fence to the plant indicated a detectable plant-related direct radiation component above background during 1997 for Bailey Cove (nearest off-site area to the plant). Since members of the public utilize mud flats in the cove at low tide for the collection of bait worms (and
~
shellfish when available), an assessment was performed to determine compliance with the dose limits of 40CFR190 (i.e., less than or equal to 25 mrem per year to the total body or any organ' except 75 mrem per year to the thyroid from the combination of direct external radiation plus the contribution from liquid and gaseous effluents). Table 2 lists the results from the combined impact of all plant sources to members of the public on the mud flats.
Dose commitments resulting from the discharge of radioactive liquid and gaseous effluents were -
estimated in accordance with the " Maine Yankee Atomic Power Station Off-Site Dose Calculation Manual" (ODCM), and are reported herein as required by ODCM Appendix C.3 (Reference 1). These dose estimates were developed using a " Method II" analysis ss described in the ODCM. A " Method II" !
analysis incorporates the methodology of Regulatory Guide 1.109 (Reference 2) and actual measured meteorological data recorded during the reporting period. For batch gas releases, the meteorological conditions concurrent with the time of release (as determined by sampling frequency and measurement)
- were used for determining doses. Table 3 lists important receptor locations as determined by the 1997 Annual Land Use Census.
All calculated liquid and gaseous pathway doses for this reporting period are well below the dose criteria'of 10CFR50,' Appendix I, and the dose limits for effluent releases stated in the Maine Yankee
-- ODCM. In addition, the total dose from the combination of direct external radiation with liquid and-gaseous effluents to the most limiting member of the public was below the dose standards of 40CFR190.

' 2.0 ' METEOROLOGICAL DATA-4 Meteorological data was collected during the reporting period from the site's 200-foot meteorological tower located approximately 1800 feet northeast of the Primary Vent Stack. The tower instrumentation is designed to meet the requirements of Regulatory Guide 1.23 (Reference 3) for j meteorological monitoring. Cumulative joint frequency distributions for wind speed, direction, and l- stability class for the~calendz.r year 1997 are provided in Tables A through H. Wind rose patterns for all stability classes during the report period are illustrated on Figures 1 and 2.
L The main release point for gaseous discharges from the plant is the 176-foot Primary Vent Stack
. (PVS), located between the Containment Building and the Primary Auxiliary Building. The PVS is treated as a mixed mode release point (part of the time as a ground level source, part of the time as elevated) dependent upon wind speed as described in Regulatory Guide 1.111 (Reference 4) since its -
height is not at least twice that of nearby structures. X/Q.and D/Q dispersion values were derived for all receptor points from the site meteorological record using a straight line airflow model. In the dispersion
- calculations, lower level wind data collected from the site meteorological tower are used "as is" for the i
ground level portion of releases in keeping with the guidance provided in the NRC meteorological .
dispersion code "XOQDOQ", NUREG/CR-2919 (Reference 5). For the elevated portion of releases, the lower level wind data are modified in accordance with NUREG/CR-2919 by a power law relationship l that extrapolates wind speed from the height of the lower level measurements to the release height of the
- PVS.

3.0 DOSE- ASSESSMENT' >
-- 3.1 Doses from I inuid Efments -
- ODCM Section 2.1.4 limits total body and organ doses from liquid emuents to members of the public in unrestricted areas to those values specified.in 10CFR Part 50, Appendix I. The limit for total
- body dose is 1.5 mrem per calendar quarter, and 3 mrem per calendar year. The limit for organ doses is 5 mrem per calendar quarter and 10 mrem per calendar year. By implementing the requirements of
- 10CFR Part 50, Appendix I, ODCM Section 2.1.4 assures that the release of radioactive material in liquid emuents will be kept "as low as is reasonably achievable."
Potential exposure pathways associated with liquid effluent from Maine Yankee are ingestion of fish / shellfish and direct exposure from shoreline sedimentation. The' drinking water and irrigation pathw'ays do not exist due to the saltwater nature of the receiving water estuary.
~
L The dose assessment for liquid effluent uses a mixing ratio (Mp) of 0.1 for fish and invertebrates, and 0.04 for shoreline exposures based on the multiport discharge diffuser constructed on the bottom of
_Back River. Usage factors ' applied to liquid effluent are listed by age group and pathway in Table 4.
The whole body and organ doses from liquid effluent were determined by summing the
. contributions from all active exposure pathways for each release of radioactivity in the reporting period.
The maximum whole body and organ doses from liquid effluent to a member of the public are given in Table 1. The estimated quarterly and annual doses due to liquid emuent discharges are well below the 10CFR50,LAppendix I dose criteria.
1 3.2 Doses From Noble Gases '
ODCM Section 2.2.4 limits the gamma air dose and beta air dose from noble gases released in i gaseous effluent from the site to areas at and beyond the site boundary to those values specified in 10CFR50, Appendix I. The limit for gamma air doses is 5 mrad per calendar quarter and 10 mrad per year. The limit for beta air doses is 10 mrad per calendar quarter and 20 mrad per year. By implementing the requirements of 10CFR50, Appendix I, ODCM Section 2.2.4 assures that the releases of radioactive
, noble gases in gaseous effluents will be kept "as low as is reasonably achievable."
Gamma and beta air doses due to noble gases released to the atmosphere were calculated for the following locations: site boundary or nearest shoreline (i.e., opposite shoreline from the plant in !
directions which border the river), nearest resident, nearest vegetable garden, nearest milk animal within
. five miles in each of the sixteen principle compass directions, and the point of approximate highest off-site ground level air concentration of radioactive materials.
The estimated quarterly and annual ganuna and beta air doses at the point of highest off-site l
. exposure are listed in Table 1. These estimated gamma and beta air doses due to noble gas radionuclide l_ , in gaseo'us effluents are well below the 10 CFR Part 50, Appendix I dose criteria. It is noted that due to
.the permanent shutdown of the plant (last power operations in December 1996) and decay of the noble gas inventory, no noble gas releases were recorded for the last three quarters of the year.
l L wmsTaummics 3.3 Doses From Iodine-131. Iodine-133. Tritiunt and Radionuclides in Particulate Form With l Half-Lives Greater Than 8 Days l
ODCM Section 2.2.5 limits the organ dose from iodine-131, iodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days in gaseous effluent to members of the public located at and beyond the site boundary to those specified in 10CFR50, Appendix I (7.5 mrem per quarter and 15 mrem per year). By implementing the requirements of 10CFR50, Appendix I, ODCM Section 2.2.5 assures that the releases ofiodines, tritium and particulates in gaseous effluent will be kept "as low as is reasonably achievable."
Potential exposure pathways associated with gaseous effluent are (i) external irradiation from radioactivity deposited on the ground surface, (ii) inhalation, and (iii) ingestion of vegetables, meat, and milk. Dose estimates were determined for site boundary locations (including opposite shoreline for boundaries next to water) and for the locations of the nearest resident, vegetable garden, and milk animal
~
in each of the~ sixteen principle c6mpa'ss' dire'ctions."The focatichs of the' nearest resident, vegetable garden, and milk animal in each sector were identified by the 1997 Annual Land Use Census as required by ODCM Section 2.4.4 (see Table 3). Additionally, doses were calculated at the point of approximate maximum ground level air concentration of radioactive materials in gaseous effluent. Doses were calculated for pathways which were determined by the field survey to actually exist. Conservatism in the dose estimates was maintained by assuming that the vegetable garden path:vay was active at each milk animal location and that the meat imestion was an active exposure pathway at each milk cow location.
Meat and milk animals were assumed to receive their entire intake from pasture during the second and third quarters. This is a conserva'ive assumption because most dairy operations utilize supplemental feeding when animals are on pasture, or actually restrict animals to full time silage feeding throughout the entire year. Usage factors for gaseous effluent are listed by age group and pathway in Table 5. Table 6 provides dose model parameter assumptions used in the dose assessment.
The organ doses were determined by summmg the contributions from all exposure pathways at each location. Doses were calculated for the whole body, GI-tract, bone, liver, kidney, thyroid, lung, and skin for adults, teenagers, children, and infants. The estimated quarterly and annual organ doses due to iodines, tritium and particulates at the location of the maximally exposed individual are reported in Table
- 1. The estimated organ doses from iodines, tritium and particulates in gaseous effluents are well below the 10CFR50, Appendix I dose criteria.
3.4 Total Dose From Direct External Radiation. Plus Liauid and Gaseous Effluents The annual (calendar year) dose or dose commitment to any member of the public dee to releases of radioactivity and direct radiation from fixed sources are limited to EPA's radiation protection standards for the uranium fuel cycle (40CFR190). The dose limits are set to less than or equal to 25 mrem per year to the total body or any organ, except the thyroid, which is limited to less than or equal to 75 mrem per year.
During 1997, TLD measurements detected exposures above background in the backyard area along the western security fence out to the edge of Bailey Cove. This direct external dose resulted from fixed sources of radioactive materials collected within the protected area fence and from within plant structures. Since the mud flats at low tide in Bailey Cove are utilized by worm diggers (and clam diggers mmemm !
when permitted), estimates of the total dose from the combination of direct external radiation plus liquid and gaseous effluents have been made (see Table 2) for determining compliance with the 40CFR190.
Direct dose M members of the public on the mud flats were derived from TLD measurements which indicated an annual dose of about 0.84 mrem on the mud flats using an estimated occupancy time for worm diggers of 325 hours0.00376 days <br />0.0903 hours <br />5.373677e-4 weeks <br />1.236625e-4 months <br /> per year, as stated in the Maine Yankee ODCM. This dose location was placed approximately 150 meters from the Primary Vent Stack in the center of the nearest portion of mud flats exposed at low tide. The vast majority of available flats above the low tide line in Bailey Cove are situated further away from this selected reference point. As a result, actual exposures from direct radiation would be less than the value applied in the estimate of direct dose (0.84 mrem) to the worm-diggers as they move across the flats.
, To the direct dose component, the dose impact from liquid and gaseous effluents affecting Bailey Cove were added. Liquid and gaseous effluents pathway doses were calculated as described above in determining compliance with as low as reasonably achievable dose objective of 10ClW50, Appendix L These dose contributions were found to be only small fractions of the direct dose estimate. Table 2 lists the dose contribution from each component (direct, liquid and gas) to the total body, maximum organ, and thyroid for the limiting member of the pablic on the mud flats. The annual total doses are all within the dose limits established in EPA's radiation protection standards contained in 40CFR190.

. ERRATA (For Past Renorts)
The following page contains an errata to the 1995 Maine Yankee Dose and Meteorological Summary Report, Table 2. The original table reported an incorrect, but conservative, gaseous -
dose estimate as part of the determination of compliance with the 10CFR190 The gaseous dose pathway represents a very small fraction of the total annual dose which is dominated by the direct l
radiation pathway. The error and its correction does not impact the previous determination of compliance with the total dose limits of 40CFR190.
