e VERMONT YANKEE EFFLUENT AND WASTE DISPOSAL SEMI-ANNUAL REPORT RADIOLOGICAL IMPACT ON MAN JULY - DECEMBER 1981

1.0 INTRODUCTION

Using actual measured effluent and meteorological data for the second six months of 1981, this report esticates potential doses 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 semi annual period. Tables 4 and 5 report the cumulative joint frequency distribution of wind speed, wind direction, and atmospheric stability observed during the second half of 1981.

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 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.

a.p.

. All: estimates of potential dose for the -second six months of 1981 were within the dose objectives set forth in Appendix I to 10CFR50. This was accomplished while the plant realized net capacity factors (design MWe) of 91.8 percent and 38.1 percent for the third and fourth 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 third and fourth quarters was 98.0 percent and 86.7 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(1), plus a source depletion model as described in Meteorology and Atomic Energy (1968),(2) and deposition velocities as given by Pelletier and Zimbrick(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 (4).

3.0 RADIOACTIVITY RELEASES 3.1 Liquid Releases During the semi-annual period, a total of 2 planned and controlled

-2 batch releases of liquid radioactivity (totaling 1.02 x 10 Ci) were discharged from Vermont Yankee in accordance with the plant's operating Technical Specifications.

All liquid ef fluent recorded for the second half of the year are listed in Tables 2A and 2B.

Approximately 67,400 liters of waste liquid were released to the Connecticut River through the plant's liquid

[

radwaste system. Average river flow for the release periods was approximately 9871 cfs.

During the same time period, there were no unp?.snned or non-routine releases of radioactivity in any liquid effluents.

3.2 Caseous Releases All gaseous effluent recorded for the second 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.

I y

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), nu,clides 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 During the fourth quarter, 2 separate batches of liquid waste totaling 67,400 liters were released. The radiological health significance of these releases were evaluated using the liquid pathway model described in NRC Regulatory Guide 1.109( ).

Site specific parameters used in applying this dosimetric model to the Vermont Yankee environment have been described and documented in the report ( ) submitted to the NRC Office of Nuclear Reactor Regulation in connection with 10CFR50, Appendix I.

The liquid pathway dose analysis for the fourth quarter was performed at a point in the Connecticut River just below Vernon Dam, 0.5 mile downstream

'f the plant. Ingestion of fish caught from the shoreline.was assumed to b'e

'se sole contribution to dose. The ingestion of river water and aquatic invertebrates was not considered since these pathways do not exist along this i

portion of the Connecticut. River or any known downstream location. The irrigation of farm land by river water was not taken into account because it

^h4

-Shas not been observ'd below th' plant. Fishing in Vernon: Pond was not-9 e

e aiw-J,#consideredfdue to the relatively smal1~ fish population and:.gecause.the w;.,,,4 shoreline access is largely restricted.

All liquid effluent from the plant was assumed to be homogeneously mixed in the volume of water wnich passed over the dam during the period of release. This leads to a conservative estimate of the radionuclide concentrations below the dam since no credit is taken for dilution or deposition in Vernon Pond. The average river flow over the dam during the time of release in the fourth quarter was 9871 cfs.

Usage f actors for adults, teenagers and children were obtained from Regulatory Guide 1.109, and doses were calculated for whole body, bone, kidney, CI-LLI, liver, thyroid and lung. The liver was the critical organ for the adult age group with Cs-134 and Cs-137 being the principal nuclides contributing to dose.

As indic' ted in Table 7, the resulting individual liver dose a

-3 commitments due to liquid releases during the fourth quarter are 2.0 x 10

~3

-3 mrem, 2.1 x 10 mrem and 1.8 x 10 mrem to the adult, teen and child age s-groups, respectively.

It should also be noted that these doses assume that each individual ingests, in the fourth quarter, one half of the total annual intake of fish recommended for a maximum individual in Regulatory Guide 1.109.

All calculated doses due to radioactivity in liquid effluent are well below the dose criteria of 10CFR50, Appendix 1.

There were no non-routine liquid releases from Vermont Yankee during the reporting period. As a result, no accidental or unplanned liquid effluents in receiving water pathways could contribute to any whole body or

_ rgan. doses to individuals in unrestricted. areas.

n 4.2 Individual Whole-Body and Skin Doses from Noble Caseous Effluents

[.

Based on the method of sector averaging discussed in " Meteorology and Atomic: Energy

'1968".and utilizing the site meteorological data recorded for, i

s this reporting period, th.e point of maximum off-site ground level air concentration of radioactive materials in gaseous effluents was determined for

.each quarter.r, Terrain height in-the vicinity of the effluent.stackewas.taken an,

=... o m i gr :.y.; ;.

t the third and fourth quarters of 1981, the point of maximum ground level air concentration was determined to be approximately WNW at 2415m from the plant stack. The undepleted X/Q's at these locations were calculated to be

~

6.6 x 10~

sec/m and 6.5 x 10~

sec/m for third and fourth ouarters p

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 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 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 cutside 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 0.11 mrem and 0.044 mrem, respectively. For the noble

. gaseous, effluent.during the fourth quarter,- the skin and whole-body doses.at the point of maximum ground level air concer.tration were calculated to be 0.047 mrem and 0.018 mrem, 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 0.12 mrem) for the third quarter of 1981 occurred in the NS<se'etor'/70:25 miles?from'the' stack.. The' fourth quarter; maximum whole-body

.f andtjkin, sit _ejboundary doses.(both- 0.046 mrem) occurred 1n: the.SSE sector.0.53 -

3 miles from the stack.

In the third quarter, the maximum skin and whole-body dose to the nearest resident (both approximately 0.09 mrem) in any direction was determined to be in the S sector, 0.34 miles from the plant stack. As a 0

result of the fourth quarter meteorology and noble gas effluents, the maximum whole-body and skin dose to the nearest resident (both approximately 0.03 mrem) in any sector occurred to the resident 0.34 miles south of the plant stack.

The resultant doses due to noble gas ef fluents for the maximum site boundary location, maximum nearest resident, and point of maximum ground level air concentration are cabulated 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 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 1.

f 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 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 fg' animals inventoried in the-site vicinity are fed stored feed throughout the d

entire year with only limited grazing allowed during the growing season.

It has also been assumed that only 50 percent of the iodine deposited 3

from gaseous effluent is in elemental form (1 ) and is available for 2

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

In the previous two reports, the dose from iodine in gaseous effluents has been based on 100 percent elemental iodine. Doses from f.f{'

consumpt' ion of water, inhalation of air or direct exposure to ground plane h1 L

activity. or airborne activity are not affected by the change..yThyrgid/ doses.

from ingestion of food will be one half those previously calculated given the same amount of iodine released.

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 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.

As a result of the milk 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 3.5 miles south-southeast of the plant. The critical organ was an infant thyroid with a calculated dose of approximately 0.01 mrem.

For the fourth quarter, with inhalation being the principle pathway of exposure, the maximum organ dose was projected to also be at the same farm. The critical organ was a child 's thyroid with a calculated dose of 6.1 x 10~

The pathways of exposure which were assumed to mrem.

exist during the third quarter at this farm include ground plane exposure, inhalation, fresh home grown vegetables and cow's milk. The pathways of exposure considered at the farm during the fourth quarter include continuous ground plane exposure, inhalation and contributions f rom stored vegetables and 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 f a rm.

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 a vegetable garden during the growing season which contributes to his or her ingestion dose. For all ground plane 4.

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 av 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 Icvels recorded during this reporting period.

The critical organs for the third and fourth quarters for the nearest resident with the most exposure were a child's thyroid and bone respectively, and for the maximum site boundary location, was calculated in both cases to be a child 's thyroid. The respective doses at these locations for the third

~4

-5 quarter were 4.6 x 10 mrem (SSE 1.3 miles) and 4.5 x 10 mrem (SSE 0.53 miles).

For the fourth quarter, the nearest resident bone dose was

-4

-5 3.3 x 10 mrem and the site boundary thyroid dose was 2.1 x 10 mrem.

4.4 Whole-Body Doses in Unrestricted Areas from Direct Radiation q7 The major source of d! rect radiation (including sky shine) frcm 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 (IIPIC) 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 J

determined to receive the maximum direct radiation from.the plant..Using g

measurements of dose rate made while the plant operated at different power levels, from shutdown to 100 percent, the total integrated dose from direct h

radiation over each three month period was determined by considering the quarterly gross megawatts generated. Field measurements of exposure, in units W

'of Roentgen, were modified by multiplying by 0.6 to obtain~ whole-b'ody' dose

, Estimates of the~ population exposure from direct ' radiation.during,the third and f ourth quarters have been made out to two miles. Beyond two miles, th dose from the turbine building is negligible.

As a result, the estimated population dose for each of the two quarters respectively was approximately

-2

-3 1.9 x 10 and 7.8 x 10 person-rem, for a total population of about 351 20,

persons. The estimated direct radiation dose at the maximum site boundary

location was approximately 3.6 mrem for the third quarter of 1981, and 1.5 mrem for the fourth. These hypothetical individual doses assume a 100 percent occupancy factor, taking no credit for the, shielding effect of any residential structure.

Table 7 summarizes these results.

4.5 Uhole-Body Doses to the General Population from all Receiving Water i.

Related Pathways f

Using the liquid pathway whole-body dose model discussed in Section 4.1, an estimate of the population dose due to the fourth quarter liquid batch j

release has been calculated. The dose per kilogram of fish ingasted at the site of the maximum individual (see Section 4.1) was assumed to apply to the entire yield of fish within 50 air miles of the plant. No credit was taken for radionuclide loss by sedimentation or further dilution by tributaries below Vernon Dam nor for the biological removal and decay of activity in the fish during the time periods when no radioactivity was being discharged from the plant.

A 1975 creel census of the Decrfield River, which is a stocked tributary of the Connecticut River downstream of the plant, reported an annual average catch of 431 fish per river mile in a 28-week season.

(Fishing j

activity is greater on the Deerfield River than on the Connecticut River because the stocked fish attract more sport fishing activity.) The average weight of these fish was conservatively estimated to be equivalent'to one pound of edible flesh. Assuming that there are 100 downstream river miles within 50 miles of the plant, the yearly yield of edible fish mass in the Connecticut River way be conservatively estimated as:

431 fish / mile, 52 weeks 1 lb., 0.453 Kg x 100 miles = 3.6 x 10 Kg/ year' 28 weeks year fish Ib.

4.6 Doses to the Ceneral Population and Average Individt el Within Fif ty Miles from Caseous Effluents Usiny, 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, tvet.ty, thirty, forty c.nd fif ty miles, and their intersection with adial lines drawn to form each of the sixteen principal compass directions. For noble gases, shole-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 it. transit of activity was assumed.

0 For the approximately 1.1 x 10 people within fifty miles of the i

plant, the third and fourth quarter whole-body doses from noble gao cloud exposure were estimated to be 1.2 person-rem and 0.53 person-rem, respectively. For the same two quarters, the average individual whole-body doses were 1.0 x 10 mrem and 4.6 x 10~ mrem, respectively. The skin

~

doses for the two quarters were 2.3 person-rem and 1.0 person-rem,

~3 respectively. The average individual skin dose was 2.0 x 10 and 8.7 x 10 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 I

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 i

food is based on the assumption that only 50 percent of the lodines is elemental and available for uptake. This is conservative but represents a change over the assumptions in the previous two reports. The total whole-body b

Measurements and Approximations of Total Radioactivity Provided below are the methods used to measure or approximate the total radioactivity in ef fluents an.3 the methods used to determine radionuclide

' composition.

i a.

Fission and Activation Cases Daily samples are drawn at the discharge of the Air Ejector.

Isotopic breakdown of the reeleases are determined from these sam ple.c. 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 +100%.

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 13 5.

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 releas ed. For each batch, station records are retained of the total activity (mci) released, concentration (uCi/ml) of gross radioactivity, volume (liters), and approximate total quantity of water (liters) used to dilute the liquid ef fluent 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.
