,_ l.0 INTRODUCTION-Using actual measured effluent and meteorological data for the first six months of 1979, this report estimates potential doses from radioactive effluents that could affect individuals and the general population near the Vermont Yankee Nuclear Power Station. Tables 1 through 3 lists the recorded radioactive effluents and solid waste for this semi-annual period.
Tables 4 and 5 report the cumulative joint-frequency distribution of wind speed, wind direction, and atmospheric stability observed during the first half of 1979, while Table 6 lists the calculated X/Q and D/Q values at different points of interest based on ths meteorological record presented in Tables 4 and 5 for both quarters. Table 7 summarizes the potential radiological dose commitments to individuala and the general population surrounding the plant. Supplemental information concerning the plant's regulatory release limits and the methods used in measuring released radioactivity is given in Appendix A.
All estimates of potential dose for the first six conths of 1979 were within the dose objectives set forth in Appendix I to 10CFR50. This was accomplished while the plant realized net capacity factors (design MWe) l of 83.1 percent and 91.0 percent for the first and second quarters, 1 1
respectively.

2.0 METEOROLOGICAL DATA Meteorological data was collected during this reporting period from
, the site's 300 foot met tower located approximately 2200 feet northwest of the reactor building, and about 1,400 feet from the plant stack. The 300 foot tower is approximately the same height as the primary plant stack (94 meters) and is designed to meet the requirements of Regulatory Guide 1.23 for meteorological monitoring.
Implementation of the Central Meteorological Monitoring System (CMMS) was completed during the-month of May, 1978. The CMMS is expected to improve data recoverability substantially by permitting routine daily (Monday through Friday) checking of data transmitted from the meteorological tower every
- 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. In addition, the on-demand, tower call-up capability from the central system location will allow instantaneous monitoring of any sensor suspected of malfunction. This feature will permit more rapid recognition of sensor or equipment malfunction, thereby reducing instrument downtime.
Combined data recoverability for the first and second quarters was 97.8 percent and 94.9 percent respectively.
X/Q and D/Q values were derived for all receptor points from the site meteorological. record for each quarter using a straight-line airflow i model. All dispersion and air concentration factors have been calculated employing appropriate source configuration considerations, as described in Regulatory Guide 1.111(1), plus a source depletion model as described inLMeteorology_and Atomic Energy (1968),(2) and deposition velocities as given by,Pelletier and Zimbrick(3).' Changes in terrain elevations'in the 1
site environment were also factored into meteorological models. A full description of the methods used to evaluate air dispersion phenomenon at the plant site is given in Vermont Yankee's 10CFR Part 50, Appendix I evaluation (4).
3.0 RADIOACTIVITY RELEASES 3.1 Liquid Releases There were no liquid releases of radioactivity from the plant during this semi-annual period.
3.2 Caseous Releases All gaseous effluent recorded for the first half of the year are listed in Tables lA through 1D. All gaseous effluents were recorded as continuous in nature, and were released to the environment via the 94 meter stack located approximately 875 feet north of the Reactor Building. As indicated in Table 1A, all gaseous effluents were well within the plants operating Technical Specification for gaseous releases of radioactivity.
In addition, there were no unplanned or non-routine releases of radioactivity in gaseous effluents during this reporting period.

4.0 DOSE ASSESSMENT Following the guidance of NUREG-0473(7) nuclides in particulate form which were not detected above the lower limit of detection, (LLD) have been reported as "less than" the LLD and have not been included in the dose calculations. However, the release rate of noble gases from the plant stack, after treatment of the gas stream from the air ejector through the augmented off gas system, is'so low that no noble gases are detectable above the LLD.
Therefore, as a conservative approach for the noble gas releases, it has been assumed for dose calculational purposes that the principal noble gases measured in the off gas mix at the air ejector are present at the LLD level determined for the plant stack.
4.1 Organ Doses to Individuals from Receiving-Water Exposure Pathways There were no routine or accidental liquid releases from Vermont Yankee during either the first or second quarters of 1979. As a result, no receiving water exposure pathways could contribute to any whole-body or organ doses to individuals in unrestricted areas.
4.2 Individual Whole-Body and Skin Doses from Noble Gaseous Effluents Based on the method of sector averaging discussed in " Meteorology and Atomic Energy - 1968", and utilizing the site meteorological data recorded for this reporting period, the point of maximum off-site ground level air concentration of radioactive materials in gaseous effluents was
~ determined for each quarter. Changing terrain heights in the vicinity of the effluent stack were taken into account in calculating these effluent ground level concentrations. For the first and second quarters of 1979, the pointslof maximum ground level air concentration were determined to be approximately SSE at 2.8 mile and NW at 1.55 mile (respectively) of the plant stack. The undepleted X/Q's at these locations were calculated to be 4.6 x 10-7 sec/m3 and 5.9 x 10-7 sec/m3 for the first and second quarters of the year, respectively.
Whole-body and skin doses were calculated at these off-site points
~
as a result of noble gas releases occurring in both quarters. The methodology applied to the dose calculations is consistent with that of Regulatory Guide 1.109(5) for an elevated release point. Dose conversion factors for noble gases and daughters were taken from Table 3-1 of this Regulatory Guide. For the beta contribution,,co the skin dose, a semi-infinite cloud model was used. The whole-body gamma dose was evaluated using a finite cloud sector average model with Gaussian activity distribution in the vertical plane. The gamma radiation received at a point of interest from a differential volume of the cloud is calculated. The radiation is then integrated over the entire cloua, taking into account of the geometry of the cloud, variation in concentration, attenuation by the interaction of photons with matter in the path between source and the receptor point, and scattering of radiation from material outside the direct path to the point of interest. An attenuation factor of 0.7 is also applied to the dose calculations to account for the dose reduction due to shielding which would be.provided by a residential structure. No additional credit is taken for decay of radionuclides in transit to the receptor point.
For the first quarter, theiskin and whole-body doses from exposure
, to noble gases at the point of maximum ground level air concentration were calculated to be 0.16 mrem and 0.078 mrem, respectively. For the noble gaseous. effluent during the second quarter, the skin and whole-body doses at the point of maximum ground level air concentration were calculated to be 0.10 mrem and 0.044 mren, respectively.
In addition, the maximum nearest resident and site boundary whole-body and skin doses have been calculated due to noble gaseous effluents from the plant stack during the reporting period. The maximum whole-body and skin site boundary doses (both 0.15 mrem) for the first quarter of 1979 occurred in the SSE sector, 0.54 miles from the stack. The second quarter maximum whole-body and skin site boundary doses (both 0.10 mrem) occurred at the same location.
l In the first quarter, the maximum skin and whole-body dose to the nearest resident (0.12 mrem and 0.11 mrem respectively) in any direction was determined to be for the skin dose in the SSE sector, 1.33 miles from
~
the plant stack, and for the whole-body dose, in the south sector, 0.33 miles . As a result of the second quarter meteorology and noble gas effluents, the maximum whole-body and skin dose to the nearest resident (both 0.083 mrem) in any sector occurred to the resident 0.33 miles south of the plant stack.
The resultant doses due to noble gas effluents for the maximum site boundary location, maximum nearest resident, and point of maximum ground level air concentration are tabulated in Table 7. All doses are conservative in that they assume 100 percent occupancy at each point. Whole-body doses consider the gamma radiation received from the effluent plume overhead.
The skin doses considers both the beta and gamma contributions at the receptor point. All doses from noble gaseous effluents are well below the dose criteria of 10CFR50, Appendix I.

4.3 Organ Doses to Individuals from Radioactive Iodine and Particulates in Gaseous Effluents The critical pathway of internal exposure to radioactive iodine and particulates, including tritium, resulting from gaseous effluents for the second quarter is through the grass-milk pathway. It is assumed that milk animals are free to graze on open pasture during the second quarter with no' supplemental feeding. This assumption is conservative since most of the milk animals inventoried in the site vicinity are fed stored feed throughout the entire year with only limited grazing allowed during the growing season.
During the winter months of the year, the dose commitment through the milk pathway and fresh vegetable ingestion is insignificant. The maximum ~
length of annual growing season is approximately six months long in this part of New England. Therefore, the milk pathway and vegetable ingestion doses for the first quarter are the result of activity deposited on feed and vegetables grown during the growing season and allowed to decay while held in storage. As a result,'the critical pathway of exposure for radioactive iodine and particulates during the first quarter is through inhalation.
As a result of the milk and fresh vegetable pathways, the maximum dose for the second quarter from gaseous releases of radioactive iodine and particulates was determined to occur at a fars 3.5 miles south-southeast of the plant. The critical organ was an infant thyroid with a calculated dose of 0.37 mrem. For the first quarter, with inhalation being the principle pathway of exposure, the maximum organ dose was projected to also be at the farm, 3.5 miles south-southeast of the plant. The critical organ was a child's thyroid with a calculated dose of 0.12 mrem. The pathways of exposure which were assumed to exist during the second quarter at this farm include ground plane exposure, inhalation, fresh home grown vegetables and goat's milk. The pathways of exposure considered at the farm during the first quarter include continuous ground plane exposure, inhalation and contributions from stored vegetables and milk.
Table 7 shows the maximum calculated quarterly organ dose due to the combination or' exposures from all pathways which have been identified at the farm. Table 7 also shows the calculated organ doses to the highest exposed nearby resident, and potential organ doses to individuals if assumed standing at the highest ground level air concentration point on the site boundary for the entire six-month reporting period. The site boundary doses only include exposure from inhalation, and direct radiation from the ground plane. The nearest resident is assumed to have a vegetable garden during the growing season which contributes to his ingestion dose. For all ground plane exposures, the-activity is assumed to accumulate on the ground for 15 years at the rate equivalent to that observed during each quarter. This is a simplified method of approximating the average deposition over the life of the plant. The calculated dose from direct exposure to activity a
on the ground thus represents the dose an individual would see in each quarter if the plant had been operating 15 years. This approach is very conservative, but shows the relative impact the plant would have on the dose commitment over its operating life if the releases were to continue at the levels recorded during this reporting period.
t The critical organ for the first and second quarters at the highest exposed nearest resident, and maximum site boundary location, was calculated
- to be a child's thyroid. The respective doses at these locations for the first quarter were 0.069 mrem (SSE 1.33 miles) and 0.0019 mrem (SSE 0.54 miles). For the second quarter,.the respective doses were 0.015 mrem (NW 1.35 miles) and o.9 x 10-4 mrem (SSE 0.54 mile).
4.4 Whole-Body Doses in Unrestricted Areas from Direct Radiation The major source of direct radiation (including sky shine) from the station is due to N-16 decay in the turbine building. Because of the orientation of the turbine building on the site, and the shielding effects of the adjacent reactor building, only the seven westerly sectors (SSW -
NNW) see any significant direct radiation.
High pressure ionization chamber (HPIC) measurements have been made in the plant area in order to estimate the direct radiation from the station.
The chamber was located at a point along the west site boundary which has been determined to receive the maximum direct radiation from the plant.
Using measurements of dose rate made while the plant operated at different power levels, from shutdown to 100 percent, the total integrated dose from I
direct radiation over each three month period was determined by considering the quarterly gross megawatts generated. Field measurements of exposure, r
in units of Roentgen, where modified by multiplying by 0.6 to obtain whole I
-body dose equivalents, in units of rem, in accordance with recommendations of HASL report- 305(6) for radiation fields resulting from N-16 photons.
Estimates of the population exposure from direct radiation during the first and second quarters have been made out to two miles. Beyond two miles, the dose from the turbine building is negligible. As a result, the estimated population dose for each of the two quarters respectively was approximately 1.7 x 10-2 and 1.9 x 10-2 man-rem, for a total population
. of about 351 persons. The estimated direct radiation dose at the maximum site boundary location was approxima'.ely 3.1 mrem for the first quarter
, of 1979, and 3.4 mrem for the second. These hypothetical individual doses ast,ume a 100 percent occupancy factor, taking no credit for the shielding effect of any residential structure. Table 7 summarizes these results.
4.5 Whole-Shdy Doses to the General Population from all Receiving Water Related Pathways Since there were no radioactive liquid effluents released from the plant during the reporting period, there are no related population or ,
individual doses from receiving-water pathways.
4.6 Doses to the General Population and Average Individual Within Fif ty Miles from Gaseous Effluents Using site meteorological data in Tables 4 and 5, quarterly average X/Q values were determined for each sector formed by placing radial rings from the plant at distances of one, two, three, four, five, ten, twenty, i thirty, forty and fifty miles, and their intersection with radial lines 1
drawn to form each of the sixteen principal compass directions. For noble I i-gases, zwhole-body and skin doses were calculated for each sector and multiplied by the estimated population within each sector to determine the sector man-rem. No credit for decay in transit of activity was assumed.
For the approximately 1.1 x 10 6 people within fifty miles of the plant, the first and second quarter whole-body doses from noble gas cloud exposure were estimated to be 1.9 person-rem and 1.2 person-rem, respectively. For the same two quarters, the average individual whole-body
. doses were 1.7 x 10-3 mrem and 1.1 x 10-3 mrem, respectively. The skin doses for the two quarters were 3.2 person-rem and 2.0 person-rem, respectively.
The average individual skin dose was 2.8 x 10-3 and 1.7 x 10-3 mrem for the first and second quarters.
Table 7 also indicates the population whole-body and thyroid dose commitments from radioactive iodine and particulates (including tritium) released from the plant in gaseous waste. The pathways of exposure which have been considered for the 50 mile population include inhalation, ingestion of vegetables, milk and meat produced within 50 miles, and the direct exposure to activity deposited aan the ground plane. The total whole-body and thyroid dose commitments for the first quarter were calculated to be .
4.8 x 10-2 person-rem and 0.67 person-rem respectively. For the second quarter, these doses were 1.5 x 10-2 person-rem and 0. 61 person-rem respectively.

EFFLUENT AND-WASTE DISPOSAL SEMIANNUAL REPORT Supplemental Information January - June 1979 Facility: Vermont Yankee Nuclear Power Station Licensee: Ve,rmont Yankee Nuclear Power Corporation
- 1. Regulatory Limite
- a. Fission and activation gases: 0.08/EY C1/sec.
'b. Iodines: 0.48 uC/sec.
- c. Particulates, half-lives >8 days: 1.6E+3 MPC Ci/sec.
- d. Liquid effluents: 1.03-7 uC/ml 1 (HTO: 3.0E-3pC/ml, dissolved Noble gases: 4.0E-SuC/ml).
Identified isotopic limits are found in 10CFR20 App. B, Table II, Column 2.
- 2. Maximum Pe_rmissible Concentrations Provided below are the MPC's used in determining allowable release rates or concentrations.
- a. Fission and activation gases: No MFC limits
- c. Particulates, half-lives >8 days: See 10CFR20, App. B. Table II, Column 1.
- d. Liquid effluents: See 10CFR20, App. B, Table'II, Column 2.
- 3. Average Energy Provided below are the ave' rage energy (E) of the radionuclide mixture in releases of fission and activation gases, if applicable. ,
- a. Average gamma energy: 1st Quarter 0.236 Me'/ V dis.
2nd Quarter 1.11 MeV7 dis. .
.b. Average beta energ/: Not Applicable
- 4. Measurements and Approximations of Total Radioactivity Provided below' are the methods used to measure or approximate the total radio-activity-in effluents and the methods used to determine radionuclide composition.
- a. Fission and Activation Cases Daily sampits are drawn at the discharge of the Air Ejector. Isotopic breakdown of the releases are determined from these samples. A logarithmic
- v . ** _2_
.e chart of the stack gas monitor is read daily to determine the gross release rate. At the very low release rates normally encountered during operation with the Agumented Off Cas system the error of release rates may be approxi-mately 2100%.
- b. Iodines Continuous isokinetic samples are drawn f rom the plant stack through a particulate filter and charcoal cartridge. The filters and cartridge are-removed weekly (if releases are less than 4% of the Tech Spec limit), or daily (if they are greater than 4% of the limit), and are analyzed for radio-iodine 131, 132. 133, 134, and 135. The iodines found on the filter are added to those a the charcoal cartridge. The error involved in these steps may be approximately 250%.
- c. Particulates The particulate filters described in b. above are also counted for particulate radioactivity. The error involved in this sample is also approximately 250%.
- d. Liquid Effluents Radioactive liquid effluents released from the facility are continuously monitored. Measurements are also made on a representative sample of each batch of radioactive liquid effluents released. For each batch, station records'are retained of the total activity (mC1) released, concentration (pC1/ml) of gross radioactivity, volume (liters), and approximate total quantity of water (liters) used to dilute the liquid ~ effluent prior to release to the Connecticut River.
Each batch of radioactive liquid effluent released is analyzed for gross gamma and gamma isotopic radioactivity. A monthly proportional composite sample, comprising an aliquot of each batch released during a month, is also analyzed for tritium, SR-89, SR-90, gross beta and gross alpha radioactivity, in addition to gamma spectroscopy.
There were no liquid releases during the reporting period.
