VERMONT YANKEE EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT RADIOLOGICAL IMPACT ON MAN THIRD AND FOURTH QUARTERS 1984 I

1.0 INTRODUCTION

I Using actual measured effluent and meteorological data for the second six months of 1984, this report estimates potential doses from radioactive I 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 cumul'ative joint frequency distribution of wind speed, wind direction, and atmospheric stability observed during the second half of 1984.

Figures lA and 18 summarize wind speed and direction in a wind rose. Table E lists the calculated X/Q and D/Q values at different points of interest based I 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 ghen in Appendix A. All estimates of potential dose for the second six months of 1984 were within the dose objectives set forth in Appendix I to 10CFR50. During the second half of 1984 the plant realized capacity f actors (design MWe) 'of 29.2 percent and 99.8 percent for the third and fourth quarters, respectively.

l I 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 third and fourth quarters was 98.3 percent and 99.2 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 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 Liouid Releases There were no liquid releases of radioactivity from the plant during this semiannual period. .

I 3.2 Gaseous Releases I All gaseous ef fluent recorded for the second half of the year are listed in Tables lA through 10. 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.

I In addition, there were no unplanned or non-routine releases of radioactivity in gaseous effluents during this reporting period.

I 4.0 DOSE ASSESSMENT I 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, af ter 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 I releases, it has been assumed for dose calculation purposes that the principal noble gases measured in the of f-gas mix at the air ejector are present at the LLO level determined for the plant stack.

4 .1 Organ Doses to Individuals from Receivinq-Water Exposure Pathways There were no routine or accidental liquid releases from Vermont Yankee during the second half of 1984, iss a result, no receiving water exposure pathways could contribute to any whole body or organ doses to individuals in I 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" (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 ground level concentrations. For both the third and fourth quarters of 1984 the point of maximum off-site ground level air concentration was determined to be in the NW sector, approximately 2900 meters f rom the plant stack. The undepleted X/Q's 3 3 at these locations were calculated to be 6.8E-07 sec/m and 6.3E-07 sec/m for the third and fourth quarters of the year, respectively.

B Whole-body and skin doses were calculated at thosg 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 (Reference 5) for an elevated release point. Oose conversion factors for noble gases and daughters were taken from Table 8-1 of this Regulatory Guide. For the beta contribution to the skin dose, a semi-infinite cloud model was used. The whole-body gamma dose was evaluated using a finite cloud I 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 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 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 third 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 5.4E-02 mrem and 2.0E-02 mrem, respectively. For the noble gas effluents during the fourth quarter, the skin and whole-body doses at the point of maximum ground level air concentration were calculated to be 9.6E-02 mrem and 3.5E-02 mrem, respectively.

I 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 (6.6E-02 and 7.8E-02 mrem respectively) for the third quarter of 1984 occurred in the South sector, 400 meters from the stack. The fourth quarter maximum site boundary whole-body and skin doses (1.lE-01 mrem and 12.E-01 mrem, respectively) also occurred in the South sector 400 meters from the stack. For the third quarter, the maximum nearest I resident whole-body and skin doses (4.9E-02 mrem and 5.8E-02 mrem, respectively) in any direction were determined to be in the South sector, 550 meters from the plant stack. As a result of the fourth quarter meteorology l

and noble gas effluents, the maximum nearest resident wh@le-bsdy and skin doses (7.7E-02,and 8.9E-02 mrem respectively) in any sector also occurred in the South sector, 550 meters from 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 ganu radiation received from the effluent plume overhead. The I 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 1.

4.3 Oroan Doses to Individuals f rom 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 third quarter is through the grass-milk pathway. It is assumed that milk animals are free to graze on open pasture during the third 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 (Ip ) and is available for uptake.

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

i 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 l

of New England. Therefore, the milk pathway and vegetable ingestion doses for the fourth 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 fourth quarter is through inhalation.

\

lI I

As a result of the cilk and fresh vegetable pathways, the maximum dose for the third quarter from gaseous releases of radioactive iodine and particulates was determined to occur at a farm 3000 meters west-northwest of the plant. The critical organ was a infant's thyroid with a calculated dose of approximately 3.0E-02 mrem. For the fourth quarter, with inhalation being the principal pathway of exposure, the maximum organ dose was projected to be at a farm 5600 meters south-southeast of the plant. The critical organ was I the liver of a child, with a calculated dose of 5.2E-04 mrem. The pathways of exposure which were assumed to exist during the fourth quarter at this farm include ground plane exposure, inhalation, and contributions from stored vegetables and milk. The pathways of exposure considered at the maximum farm location during the third quarter include continuous ground plane exposure, inhalation f resh honie ' grown vegetables, meat, and cow's milk.

I 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 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 include only exposure from inhalation, and direct radiation from the ground plane. The nearest resident is assumed to have 6 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 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 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 comitment over its operating life if the releases were to continue at the levels recorded during this reporting period.

The maximum critical organ dose for the third quarter for the nearest I resident was to the thyroid of a child. This dose was calculated to be 9.8E-04 mrem (SSE, 2100 meters). The maximum critical organ dose for the fourth quarter for the nearest resident was also to the liver of a child. The dose to this critical organ was calculated to be 2.lE-04 crem (SSE, 2100 meters). l The critical organ foi the third quarter for the maximum site boundary location was to the thyroid of a child. The dose to this critical organ was calculated to be 1.5E-04 mrem (SSE, 850 meters). The critical organ for the fourth quarter for the maximum site boundary location was to the skin, equally to all age groups. This dose was calculated to be 6.2E-05 mrem (SSE, 850 meters).

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 to 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 direct radiation over each three month period was determined by considering the l quarterly gross megawatts generated. Field measurements of exposure, in units of Roentgen, were modified by multiplying by 0.6 to obtain whole-body dose I equivalents, in units of rem, in accordance with recommendations of HASL report 305 (Reference 6) for radiation fields resulting from N-16 photons.

Estimates of the population exposure from direct radiation during the third and fourth quarters have been made out to two miles. Beyond two miles, the dose from the turbine building is negligible. As e result, the estimated l

population dose for each of the two quarters respectively was approximately 7.6E-03 and 2.4E-02 person-rem, for a total population of about 420 persons.

The estimated direct radiation dose at the maximum site boundary location was lI approximately 1.2 mrem for the third quarter of 1984, and 3.6 mrem for the

' I

fourth. These site boundary d:scs assume a 100 percent cccupancy factor, taking no credit for the shielding ef fect of any structure. Table 7 sunmarizes these results.

4.5 Whole-Bodv Doses to the General Population f rom all Receiving Water Related Pathways There were no routine or accidental liquid releases from Vermont Yankee during the second half of 1984.

.I 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/0 values were determined for each sector formed by placing radial rings f rom 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 I 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 fifty miles of the plant, the third and fourth quarter whole-body doses from noble gas cloud exposure were estimated to be 5.2E-01 person-rem and 9.5E-01 person-rem, respectively.

For the same two quarters, the average individual whole-body doses were 3.4E-04 mrem and 6.1E-04 mrem, respectively. The skin doses for the two i quarters were 1.3 person-rem and 2.4 person-rem, respectively. The average individual skin dose was 8.6E-04 and 1.5E-03 mrem for the third and fourth

! 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 l

_g.

i l

food is based on the assumption that cnly 50 p2rcent of the icdines is elemental and available for uptake. The whole-body and thyroid dose commitments for the third quarter were calculated to be 9.6E-03 person-rem and 8.5E-02 person-rem, respectively. For the fourth quarter, the whole-body and thyroid dose commitments were 8.7E-03 person-rem and 8.9E-03 person-rem, respectively.

1. Regulatory Limits

a. Fission andI activation gases: 0.08/E7 Ci/sec

b. Iodines: 0.48 pCi/sec

c. Particulates, half-lives > 8 days: 1.6E+3 MPC, C1/sec

d. Liquid effluents: 1.0E-07 pC1/ml (HTO: 3.0E-03 pCi/mi, 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. 8. Table II, Column 1.

d. Liquid effluents: See 10CFR20, App. 8. Table II, Column 2.

3. Average Energy Provided below are the average energy (E) of the radionuclide mixture in releases of fission and activation gases, if applicable.

-Al-

a. Average gamma energy: 3rd Quarter 4.99E-1 Mev/ dis 4th Quarter 1.10E+00 Mev/ dis

b. Average beta energy: Not Applicable

4. Measurements and Approximations of Total Radioactivity Provided below are the methods used to measure or approximate the total radioactivity in effluents and the methods used to determine radionuclide 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 1100 .

b. Iodines Continuous isokinetic samples are draw'n from 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 radioiodine 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 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 150 .

-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 (mC1) released, concentration (uC1/ml) of gross radioactivity, volume (liters), and approximate total quantity of I 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.

5. Batch Releases

a. Liquid .

There were no routine liquid batch releases during the reporting period.

b. Gaseous There were no routine gaseous batch releases during the reporting period.
