VERMONT YANKEE EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT RADIOLOGICAL IMPACT ON MAN THIRD AND FOURTH QUARTERS 1983

1.0 INTRODUCTION

Using actual measured effluent and meteorological data for the second six months of 1983, this report estimates potential doses from radioactive Gffluents 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 1983.

Figures lA and 1B summarize wind speed and direction in'a wind rose. Table 6 lists the calculated X/Q and D/Q values at different points of interest based en 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 ccncerning the plant's regulatory release limits and the methods used in measuring released radioactivity is given in Appendix A.

All estimates of pstential dose for the second six months of 1983 were within the dose cbjectives set forth.in Appendix I to 10CFR50.

During the~second half of 1983 the plant realized net capacity factors (design MWe) of-91.9 percent and 98.5

. percent for the third and fourth quarters, respectively.

f 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 seccnd quarters was 98.6 percent.and 97.0 percent, respectively.

X/Q and D/0 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

'velccities 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 L1auid Releases There were no liquid releases of radioactivity from the plant during this semiannual period.

3.2 Gaseous Releases All gaseous effluent recorded for the second half of the year are listcd in Tables lA through 10. All gaseous effluents were recorded as c ntinuous 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 cperating Technical Specification for gaseous releases of radioactivity.

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

l.

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 th? dose calculations. However, the release rate of noble gases f rom the plant stack, after treatment of the gas stream from the air ejector through th2 augmented off-gas system, is so low that no noble gases are detectable labove the LLD. Therefore, as a conservative approach for the noble gas releases, it has been assumed for dose calculation purposes that the principal n ble gases measured in the off-gas mix at the air ejector are present at the

.LLD level determined for the plant stack.

4.1 Oraan Doses to Individuals from Receivina-Water ExDosure Pathways There were no routine or accidental liquid releases from Vermont Yankee during the second half of 1983. 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" (Reference 2), and utilizing the site meteorological f data recorded for,this reporting period, the point of maximum off-site ground level air concentration of radioactive materials in gaseous ef fluents was determined for each quarter.

Terrain height in the vicinity of the effluent

-stack was taken into account in calculating these effluent ground level lctncentrations.

For both the third and fourth quarters of 1983 the point of

maximu] off-site ground level air concentration was determined to be approximately in the WNW sector, 2415 meters from the plant stack. The undIpleted X/Q's at these locations were calculated to be 6.8E-07 sec/m and 3

5.2E-07 sec/m for.the third and fourth quarters of the year, respectively.

.Whole-body and skin doses were ca cu ated at t ese off-site points as a l

l h

result of noble gas releases occurring in both quarters. The methodology appli:d to the dose calculations is consistent with that of Regulatory Guide 1.109 (Reference 5) for an elevated release point.

Dose conversion factors for n:ble 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

'.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 cloud, taking into account the' geometry of the

( citud, 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 1

noble gases at the point of maximum ground level air concentration were

- calculated to be 9.3E-02 mrem and 3.7E-02 mrem, respectively. For the noble b

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 7.6E-02 crem and 3.1E-02 mrem, respectively.

In addition, the maximum nearest resident and maximum site boundary wh31e-body and skin doses have been calculated due to noble gas effluents from l;the plant stack during the reporting period. The maximum site boundary I whole-body and skin doses (both 1.1E-01 mrem) for the third quarter of 1983 I occurred'in the S sector, 400 meters from the stack. The fourth quarter maximum site boundary whole-body and skin doses (7.8E-02 mrem and 8.0E-02 mrem, respectively) occurred in the SSE sector 850 meters from the stack.

For the third quarter, the maximum nearest resident whole-body and skin doses'(7.9E-02 mrem and 8.0E-02 mrem, respectively) in any direction were

, determined to be in the S' sector, 550 meters from the plant stack. As a

. result of the fourth quarter meteorology and noble gas effluents, the maximum.. ~2

. -.. - ~

nearest resident whole-body and skin doses (both approximately 5.5E-02 mrem) 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 mL.imum site b:uadary location, maximum nearest resident, and point of maximum ground level air ccncentration 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 f rom the ef fluent plume overhead. The skin d:ses consider both the beta and gansna contributions at the receptor

. point. All doses from noble gaseous effluents are well below the dose criteria of 10CFR50, Appendix 1.

.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 ithird 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 (I ) and is available for uptake.

2 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 Gilk pathway and fresh vegetable ingestion is insignificant. The maximum llengthofannualgrowingseasonisapproximatelysixmonthslonginthispart

!of New England. Therefore, the milk pathway and vegetable ingestion doses for lthe fcurth 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 iparticulates during the fourth quarter is through inhalation..-

As a result of the milk and f resh 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 th? plant.

The critical organ was a child's thyroid with a calculated dose of approximately 1.lE-03 mrem.

For the fourth quarter, with inhalation being the 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

, the b:ne of a child, with a calculated dose of 8.4E-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 1: cation during the third quarter include continuous 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 tw) farms.

Table 7 also shows the calculated organ doses to the highest exp: sed 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 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 commitment over its operating life if the releases were to continue at the levels recorded during this reporting period.

The critical organs for the third quarter for the nearest resident with the most exposure were the GI-LLI and thyroid of a child. The doses to these critical organs were calculated to be 3.lE-04 mrem (SSE, 2100 meters). The..

ritical organ for the fourth quarter for the nearest resident with the most xposure was_the bone of a child. The dose to this critical organ was alculated.to be 3.3E-04 mrem (SSE, 2100 meters).

The critical organ for the third quarter for the maximum site boundary Occation was the thyroid of an infant, child, teen, and adult. The dose to D is critical organ was calculated to be 1.8E-04 mrem (SSE, 850 meters). The h

ritical organs for the fourth quarter fcr the maximum site boundary location Wera the thyroid, GI-LLI, and whole body of a child, teen, and adult. The dises to trase critical organs were calculated to be 4.2E-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 Staticn is due to N-16 decay in the turbine building. Because of the 3rientation of the turbine building on the site, and the shielding effects of Ghe adjacent reactor building, only the seven westerly sectors (SSW to NNW)

Bee any significant direct radiation.

-High pressure ionization chamber (HPIC) measurements have been made in Ghe plant area in order to estimate the-direct radiation f rom the station.

$hechamberwaslocatedatapointalongthewestsiteboundarywhichhasbeen determined to receive the-maximum direct radiation f roa the plant.

Using j

measurements of dose rate made while'the plant operated at different power levels, f rom shutdown to 100 percent, the total integrated dose from direct radiation over each three' month period was determined by considering the Guarterly gross megawatts generated.

Field measurements of exposure, in units af Rrentgen, were modified by multiplying by 0.6 to obtain whole-body dose l equivalents, in units of rem, in accordance with recommendations of NASL

!rcport 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, f

the dose from the turbine building is negligible. As a result, the estimated l

L

population dose for each of the two quarters respectively was approximately 2.3E-02 and 2.4E-02 person-rem, for a total population of about 402 persons.

The estimated direct radiation dose at the maximum site boundary location was

approximately 3.6E+00 mrem for the third quarter of 1983, and 3.8E+00 mrem for the'fcurth. 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 Receivine Water Related Pathways

.There were no routine or accidental liquid releases from Vermont Yankee during the first half of 1983.

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 fif ty 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 fer d2 cay in transit of activity was assumed.

For the approximately 1.53E+06 people within fif ty miles of the plant, the third and fourth quarter whole-body doses from noble gas cloud exposure were Gstimated to be 9.8E-01 person-rem and 8.4E-01 person-rem, respectively.

For the same two quarters, the average individual whole-body doses were 6.4E-04 mrem and 5.5E-04 mrem, respectively. The skin doses for the two quartcrs were 2.2E+00 person-rem and 1.9E+00 person-rem, respectively. The

-average individual skin dose was 1.4E-03 and 1.2E-03 mrem for the third and fourth quarters.

_g-

Table 7 also indicates the population whole-body and thyroid dose connitments 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 fcod is based on the assumption that only 50 percent of the iodines is elemental and available for uptake. The whole-body and thyroid dose cmumitments for the third quarter were calculated to be 1.2E-02 person-rem and 1.4E-02 person-rem, respectively.

For the fourth quarter, the whole-body and thyroid dose commitments were 9.5E-03 person-rem and 9.3E-03 person-rem, resp 7ctively.

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 radionucl.ide 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 drawn 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 50.

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.

~

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 (mci) released, concentration (yCi/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 proportionci 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 speciroscopy.

There were no liquid releases during the reporting period.
