VERM0KT YANKEE EFFLUENT AND WASTE DISPOSAL SEMIANUUAL REPORT RADIOLOGICAL IMPACT ON MAN FIRST AND SECOND QUARTERS 1984

1.0 INTRODUCTION

Using actual measured effluent and meteorological data for the first six months of 1984, this report estimates potential d'ses from radioactive effluents that could affect individuals and the general population near the Vermont Yankee Nuclear Power Station. Tables 1 through 3 list the recorded radioactive effluents and solid waste for this semiannual 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 1984.

Figures 1A and 1B summarize wind speed and direction in a wind rose. Table 6 lists the calculated I/Q and D/Q values at different points of interest based on the meteorological record presented in Tables 4 and 5 for both quarters.

Table 7 summarizes the potential radiological dose commitments to individuals 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 months of 1984 were within the dose objectives set forth in Appendix 1 to 10CFR50. During the first half of 1984 the plant realized net capacity factors (design MWe) of 92.5 percent and 79.4 percent for the first and second quarters, respectively.

2.0 METEOROLOGICAL DATA Meteorological data was collected during this reporting period from the site's 300-foot met tower located approximately 2,200 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. Combined data recoverability for the first and second quarters was 92.5 percent and 99.5 percent, respectively.

I/Q and D/Q values were derived for all receptor points from the site meteorological record for each quarter using a straight-line airflow model.

All dispersion and air concentration factors have been calculated employing appropriate source configuration considerations, as described in Regulatory Guide 1.111 (Reference 1), plus a source depletion model as described in

" Meteorology and Atomic Energy - 1968" (Reference 2), and deposition velocities as given by Pelletier and Zimbrick (Reference 3). Changes in terrain elevations in the 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 (Reference 4).

3.0 RADI0 ACTIVITY RELEASES 3.1 Liquid Releases There were no liquid releases of radioactivity from the plant during this semiannual period.

3.2 Caseous Relesses All gaseous effluents 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 (Reference 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 calculation 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 Receivint-Water Exposure pathways There were no routine or accidental liquid releases from Vermont Yankee during the first half of 1984. 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 und Skin Doses from Noble Gaseous Effluents Based on the method of sector averaging discussed in " Meteorology and Atomic Energy - 1968" (Reference 2), 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. Terrain height in the vicinity of the effluent stack was taken into account in calculating these effluent grcund level concentrations. For both the first and second quarters of 1984 the point of maximum off-site ground level air concentration was determined to be approximately in the S sector, 4025 meters from the plant stack. The undepleted X/Q's at these locations were calculated to be 5.3E-07 sec/m and 4.7E-07 sec/m 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 l.109 (Reference 5) for an elevated release point. Dose conversion factors for noble gases and daughters were taken from Table B-1 of this Regulatory Guide. For the beta contribution to the skin dose, a semi-infinite cloud todel was used. The whole-body gamma dose was evaluated using a finite cloud .

cector average model with Caussian 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 cloud, taking into account the geometry of the cloud, variation in concentration, attenuation by the interaction of photons with matter in the path between source and the ree&ptor 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, the skin and whole-body doses from exposure to noble gases at the point of maximum ground level air concentration were calculated to be 7.8E-02 mrem and 3.6E-02 mrem, respectively. For the noble gan effluents during the second quarter, the skin and whole-body doses at the point of maximum ground level air concentration were calculated to be 6.2E-02 mrem and 2.9E-02 mrem, respectively.

In addition, the maximum nearest resident and maximum site boundary whole-body and skin doses have been calculated due to noble gas effluents from the plant stack during the reporting period. The maximum site boundary whole-body and skin doses (both 1.3E-01 mrem) for the first quarter of 1984 occurred in the S sector, 400 meters from the stack. The second quarter maximum site boundary whole-body and skin doses (both 1.lE-01 mrem)also occurred in the S sector, 400 meters from the stack. For the first quarter, the maximum nearest resident whole-body and skin doses (both 9.6E-02 mrem) in any direction were determined to be in the S sector, 550 meters from the plant stack. As a result of the second quarter meteorology and noble gas effluents, the maximum nearest resident whole-body and skin doses (7.8E-02 mrem and 7.9E-02 mrem, respectively) in any sector also occurred in the S sector, 550 meters from the plant stack.

The resultant doses due to noble gas effluents for the maximum site I

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 consider 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. It has also been assumed that only 50 percent of the iodine deposited from gaseous effluent is in elemental form (I 2) and is available for uptake.

This assumption is conservative for long-term doses (see p. 26, Reference 5).

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 farm 2500 meters south of the plant. The critical organ was an infant's thyroid with a calculated dose of approximately 1.5E-02 mrem. For the first quarter, with inhalation being the

I principal pathway of exposure, the maximum organ dose was projected to also be at a farm 5600 meters south-southeast of the plant. The critical organ was 1

the CI-LLI of a teen or child, with a calculated dose of 1.4E-03 mrem. The pathways of exposure which were assumed to exist Faring the first quarter at this farm include ground plane exposure, inhalation, and contributions from stored vegetables, meat, and cow's milk. The pathways of exposure considered at the maximum farm location during the second quarter include ground plane exposure, inhalation, fresh home grown vegetables, meat, and cow's milk.

Table 7 shows the maximum calculated quarterly organ dose due to the combination of exposures from all pathways which have been identified at the two farms. Table 7 also shows the calculated organ deses 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 include only 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 or her ingestion dose. For all ground plane exposures, the activity is assumed to accumulate on the ground for 15 years at the rate equisalent 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 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.

The critical organ for the second quarter for the nearest resident with the most exposure was the thyroid of a child. The dose to this critical organ was calculated to be 6.3E-04 mrem (SSE, 2100 meters). The critical organ for the first quarter for the nearest resident with the most exposure was the CI-LLI of a teen. The dose to this critical organ was calculated to be 6.5E-04 mrem (SSE, 2100 meters).

4 t The critical organ for the second quarter for the maximum site boundary location was the thyroid of a child. The dose'to this gritical organ was calculated to be 6.0E-05 mrem (SSE, 850 meters). The critical organ for the first quarter for the maximum site b$undary location was the skin of an

  • infant, child, teen, or adult. The coses to 3hese critical organs wern calculated to be 8.4E-05 mrem (SSE, 850 meters).

4.4 Whole-Body Doses in Uncertricted Areas from Direct Radiat*p;n ' ' 'N

't The major source of direct radiatiya (incluolag 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 to NNW) see any significant direct radiation.

High pressure ionization chamber (HP11) measurements have been made in the plant area in order to estimate tne direct radiation from the station.

Thechamberwaslocatedatapointylongthewestsiteboundarywhichhasbeen determined to receive the maximum Cicect 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 direct radiation over each three month period was determined by considering the quarterly gross megawatts generated. Field measurements of exposure, in units of Roentgen, were modified by multiplying by 0.6 to obtain whole-body dose' equivalents, in units of rem, in accordance with recommendations of RASL [

report 305 (Reference 6) for radiation fields resulting from N-16 photons: '

Estimates of the population exposure from direct radiation during the firstandsecondquartershavebeenmadeouttotwomild's. Beyond two milea, '

the dose from the turbine building is negligib'e. As a result, the estimated population dose for each of the two quarters respect 1;;ely was approximately 2.3E-02 and 2.0E-02 person-rem, for a total population of about 420 persons.

The estimated direct radiation dose at the maximum site boundary location was approximately 3.5 mrem for the first quarte 7 of 1984, and 3.0 mrem for the second. These site boundary doses assume a 100 percent occupancy factor,  !

taking no credit for the shielding effect of any structure. Table 7 summarizes these results.

4.5 Whole-Body Doses to the General Population from all heceivb.x Water Related Pathways l

There were no routine or accidental liquid releases from Vermont Yankee

  • during the first half of 1984.

4.6 Doses to the General Population and Average Individual Within Fifty Miles from Gaseous Effluents Using site meteorological data in Tables 4 and 5, quarterly average I/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, thirty, forty and fifty miles, and their intersection with radial lines drawn to form each of the sixteen principal compass directions. For noble gases, whole-body and skin doses were calculated for each sector and multiplied by the estimated population within each sector to determine the sector person-rem. No credit for decay in transit of activity was assumed.

For the approximately 1.54E+06 people within fif ty miles of the plant, the first and recond quarter whole-body doses from noble gas cloud exposure were estimated to be 0.92 person-rem and 0.76 person-rem, respectively. For the same two quarters, the average individual whole-body doses were 6.0E-04 mrem and 4.9-04 mrem, respectively. The skin doses for the two quarters were 2.1 person-rem and 1.7 person-rem, respectively. The average individual skin doses were 1.3E-03 and 1.1E-03 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 on the ground plane. The dose due to iodines in ingested food is based on the assumption that only 50 percent of the lodines is

elemental and available for uptake. The whole-body and thyroid dose comunitments for the first quarter were calculated to be 2.5E-02 person-rem and 2.5E-02 person-rem, respectively. For the second quarter, the wnole-body and thyroid dose connaitments were 8.1E-03 person-rom and 4.2E-02 person-rem, respectively.

1. Regulatory Limits
a. Fission and activation gases: 0.08/Ey Ci/sec
b. Iodines: 0.48 pCi/sec ,
c. Particulates, half-lives > 8 days: 1.6E+3 MPC, pCi/sec
d. Liquid effluents: 1.0E-07 pCi/ml (HTO: 3.0E-03 pCi/ml, dissolved noble gases:

4.0E-05 pCi/ml) Isotopic limits are found in 10CFR20, App. B, Table II, Column 2.

2. Maximum Permissible Concentrations Provided below are the MPC's used in determining allowable release rates or concentrations.
a. Fission and activation gases: No MPC limits
b. Iodines: No MPC 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 average energy (f) of the radionuclide mixture in releases of fission and activation gases, if applicable.

-Al-l 1

i

a. Average gamma energy: 1st Quarter 1.05E+00 Mev/ dis 2nd Quart <;r 8.47E-01 Nev/ dis
b. Average beta energy: Not Applicable
4. Measurements and Approximations of Total Radioactivity I Providcd below are the methods used to measure or approximate the total radioactivity in effluents and the methods used to determine radionuclide 4

composition.

a. Fission and Activation Gases Daily samples are drawn at the discharge of the air ejector.

Isotopic breakdown of the releases are determined from these samples. A logarithmic 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 augmented off-gas system the error of release rates may be approximately tl00 .

b. Iodines Continuous isokinetic samples are drawn from the plant stack '

through a particulate filte. 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 radiciodine 131, 132, 133, 134, and 135. The iodines found on the filter are added to those on the charcoal cartridge. The error involved in these steps may be 1 approximately 150 .

c. Particulates The particulate filters described in b. above are also counted for particulate radioactivity. The error involved in this sample is also approximately !50 .

-A2-

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 (mC)) released, concentration (wCi/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 ef fluent 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.

5. Batch Releases
a. Liquid There were no routine liquid batch releases during the reporting period,
b. Gaseous 1 There were no routine gaseous batch releases during the reporting
period.

-A3-

6. Abnormal Releases l
a. Liquid There were no non-routine liquid releases during the reporting period.
b. Gaseous There were no non-routine gaseous releases during the reporting period.
