'I I. INTRODUCTION f

This report contains a summary and analysis of the radiological data collected during 1980 by the Environmental Studies Laboratory of the t Vermont Yankee Nuclear Power Corporation.

l Direct gamma radiation around the plant environs is measured with Ca F2: MN TLD badges. Vermont Yankee personnel prepare, distribute, measure I and calibrate these dosimeters. All the environmental samples were processed I by the Nuclear Services Division Environmental Laboratory, located in Westborougl., Massachusetts.

Section II of this report contains a list of all sampling stations used in 1980, as well as a tabulation of the media sampled at each location.

, Figures 1 through 6 indicate the location of the plant site, its topography, and the location of sampling stations.

I Section III summarizes the environmental data. A computer program, ERMAP, produces a digest of the 1980 measurements. Each environmental media appears according to the alphabetical order of its media code. At the top of each page, ERMAP lists the units of measurement for each media. The left-hand column contains the radionuclide which is being reported, total

number of sample analyses of that radionuclide, and the number of

?

measurements which exceed ten times the yearly average background value.

! The latter are classified as "non-routine" measurements. The next column lists the nominal lower limit of detection for each radionuclide.

I could conceivably be affected by the operation of Vermont Yankee are called

" indicator" or " Zone 1" stations. Distant stations which are beyond plant l influence are called " control" or " Zone II" stations.

ERMAP calculates a set of statistical parameters for each radionuclide. This set of statistical parameters includes separate analyses for (1) the indicator stations, (2) the control stations, and (3) the station having the highest annual mean concentrations. For each of these three i groups of data, ERMAP calculates:

,I

1) The mean value of all concentrations including values below minimum

detectable levels and negative values.

2) The square root of the mean square deviation. This is an estimate of the sample variance.

'i

3) The lowest and highest calculated concentrations.

4) The number of detectable measurements (activity which is three times greater than the standard deviation) divided by the total number of measurements.

Section IV of this report discusses the quality assurance program, which includes EPA results, and Section V discusses fallout from a Chinese atmospheric nuclear test blast.

In the final sections, we analyze the results of our efforts in

, 1980, calculate environmental radiation doses, and present our conclusion.

I IV. QUALITY ASSURANCE PROGPX1 1

I Three separate quality assurance programs were performed during I

1980 to demonstrate the validity of laboratory analyses by the NSD 1 I Environmental Laboratory.

I NSD participates in the EPA Interlaboratory Comparison (cross-check) )

Program for'those species and matrices routinely analyzed by the laboratory.

This provides an independent check of accuracy and precision of the (

laboratory analysis.

NSD maintains an intralaboratory quality control program to assure the validity and reliability of the data. This program includes quality control of laboratory equipment, use of reference standards for calibration, determination of counting efficiencies and analysis of blank and spiked I samples. The records of the quality control program are reviewed by the responsible cognizant, and corrective measures are taken whenever applicable.

A blind duplicate / replicate program is maintained in which samples are prepared from split or homogeneous media and sent to the laboratory for analysis. The results from this program are used to check for precision in laboratory analyses.

I l

Figures 7 through 9 show the results of the EPA Intercomparison Program for radionuclides in water and milk samples for 1980. Strontium 89 in milk in a July sample and Cr-51 in a February water sample fell outside of the EPA control level, all other milk and water samples were within EPA D criteria.

In March of 1980, NSD changed the method of detection of Sr-89 and Sr-90 from simple beta counting at two different times to a more reliable

.I beta-beta anticoincidence system. A negattve bias in Sr-89 measurements became apparent in late August of 1980, and processing of strontium analysis was suspended pending a system evaluation. In Septembes, the entire beta-beta anticoincidence system was recalibrated and the results showed a Sr-89

. efficiency which was approximately ten percent lower than the original calibration. All Sr-89 data generated by the beta-beta anticoincidence methodology was reviewed and positive values were updated. This problem did not affect the ability of the technique to detect Sr-89 near the 10 pCi per liter LLD requirements. ,e September EPA results were within EPA criteria for accuracy.

Concerning tha analysis of Cr-51, the analysis of Cr-51 is made difficult Lf the low branching intensity of the primary gamma line (0.099

at 320 kev), and the relatively short half-life (27.7 days) of Cr-51. A review of the gamma spectra associated with these analyses shewed no significant problems with the manner in which these analyses were conducted.

All f ttture Cr-51 analysis will be carefully reviewed; however, we feel that the expected precision utilized by the EPA to determine the normalized g deviation from the known for Cr-51 in far too restrictive.

3 The results of the blind duplicate and intracomparison QA sample I programs for the first half of 1980 showed that NSD met the criteria for precision in environmental media.

V. ATMOSPHERIC FALLOUT DURING 1980 I On Octobe.r 17, 1980, the People's Republic of China detonated a nuclear device in the atmosphere at the Lop Nor test site in northwest China.

! The explosion was estimated by the Department of Energy to be in the 200 kilotons to one megaton yield range. The clouds of radioactive debris began drif ting ove'r the western part of the United States on October 19, 1980.

Figure 10 shows the weekly measurements of airborne gross beta activity on air particulate filters from nine air saepling stations in the environs of Vermont Yankee. During November, increased airborna gross beta activity was detected on indicator and control station samples. This elevated gross beta activity continued into 1981. The fourth quarter gamma analysis of weekly composite filters from - ach location showed detectable concentrations of fallout fission products (Ce-141, Ru-103, Nb-95 and Zr-95)

J f from the Chinese test (Figures 11 to 14). These fission products were also 4

detected in air particulate filter samples from other New England sampling locations during the fourth quarter of 1980.

In October, our environmental laboratory in Westborough, I f Massachusetts, began operation of a control air monitoring sampler. The measurements from this station are in addition to the background measurements required by our Technical Specifications. From November 13, the laboratory measured detectable concentrations of the fallout fission products from the Chinese test.

' VI. ANALYSIS OF ENVIRONMENTAL DATA i

I

( The analysis of environmental data can be divided into three sections: airborne radioactivity, waterborne activity, and direct exposure if

=

(TLD) measurement. A discussion of each environmental media withir. these sections will follow.

1. Airborne (a) Air Particulate Filters Air monitoring stations are established at a total of nine locations. Airborne particulates are collected by passing air u through a fiber filter; these filters are collected weekly and lg held for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before being analyzed for gross beta

!g

, activity to allow for the decay of radon and thoron daughter products. Weekly composite air filters from each location are analyzed quarterly for gamma emitting nuclides.

Figure 10 shows the weekly concentration of gross beta activity during 1980. Stations 14 and 10 showed higher gross beta activity than the other sampling stations during the second and third week of Jr.uary, respectively. Camma analysis performed on first-quarter composite samrles showed detectable concentrations of Co-60 in air particulate filter samples from stations 10, 13 and l

14. This Co-60 activity was most likely related to cormal plant

]

gaseous releases during the first quarter of 1980. The whole W body dose from inhalation of this radionuclide was minimal

I

' 48

I k (approximately 2.11 E-5 mrem) and would have insignificant health ,

l

In November, increased gross beta activity was detected in indicator and control station samples. The fourth quarter gamma analysis of air particulate samples showed detectable codcentrations of Ce-141, Ru-103, Nb-95 and Zr-95 (Figures 11 to 14). This activity was related to the detonation of a nuclear weapon in the atmosphere by the People's Republic of China on October 17, 1980 (see Section V).

II (b) Radioiodines lI Charcoal filters from the air sampling stations were collected and analyzed weekly for I-131 activity. Concentrations of I-131 activity in charcoal samples were below detectabla measurements during 1980.

f (c) Milk Milk was collected and analyzed monthly for gamma emitters and

. quarterly for Sr-89 and Sr-90 from four sampling stations. Durins 1980, a dete.ctable level of I-131 was measured in a milk sample t

collected from station 12, located 2.5 kilome:ers south of the lI i, plant. This activity coincided with the arrival of fresh fallout frt;m the detonation of a nuclear device by the Chinese (see Section V).

Milk samples from other New England locations exhibited detectable measurement of I-131 during this period of time.

Detectable concentrations of Cs-134 were measured in milk samples f collected on May 8, 1980, from three s apling locations. The I,

total gaseous release of Cs-134 from the plant during the second quarter of 1980 was 2.13 x 10-5 curies. Using the methodology in Regulatory Guide 1.109 and conservative assumptions, the l

expected concentration of Cs-134 in milk at the maximum D/Q farm i location is several orders of magnitude lower than the Cs-134 levels detected in milk. Resampling of the milk was performed on May 27, 1980, and the analysis revealed no detectable level of Cs-134.

I Based on the above discussion and the fact that statior. 21, a control sample, had the highest concentration of Cs-134, we feel 4

that these samples became contaminated when they were taken back onto the plant site. More caution will be taken in the future i

to prevent cross-contamination of samples.

confidence level.

2. Waterborne l

(a) Ground Water I Ground water samples were collected and analyzed quarterly for gross beta, tritium and gamma emitting nuclides. The only detectable activity in the ground water samples was gross beta and tritium. The gross beta levels are typical of measurements made over the last few years, and one out of sixteen measurenents i of tritium showed a concentration which was greater than our three W .

sigma criteria but below the maximum detectable concentration for the analysis.

(b) River Water Il!

River water was collected from three sampling locations and analyzed monthly for gross beta and gamma emitters, and quarterly l l

for tritium. Only gross beta concentrations were greater than detectable levels. A comparison of the average gross beta activity in indicator and control samples showed that these activities I 51

iW (c) Fish Fish samples were collected in June and November from two indicator and one control station. Edible portions of the samples were t

I anlayzed for gamma emitting nuclides. Cesium 137 and naturally occurring K-40 were the only radionuclides exhibiting detectable concentrations. Comparisons of indicator Cs-137 concentrations to control samples show that the control had a higher a, rage concentration, and this activity can be attributed to the weapons test. There were no liquid releases from Vermont Yankee during 1980.

I (d) _ Aquatic Vegetation Naturally occurring K-40 was the only radionuclide measured in aquatic vegetation samples with concencrations greater than i

detectable levels.

(e) Sediment Sediment samples were collected in June and October from one control and two indicator locations. As usual, the sedimen,t samples showed detectable concentrations of naturally occurring K-40 and Th-228 plus fallout related Cs-137. The average Cs-137 concentrations in indicator and control locations were not I statistically dif ferent and are related to the residual Cs-137 activity from atmospheric nuclear tests.

VIII. CONCLUSION

] During 1980, our radiological environmental program conducted in Vermont off-site environment showed that, in general, the major radionuclides iI measured in environmental media were the naturally occurring and fallout fission products from atmospheric nuclear tests. There was no significant il

, increase in environmental radioactivity due to the operation of Vermont i

', Yankee.

The level of radioactivity in materials in environmental media lI indicatet that public intake is less than one percent of that recommended ,e

, in Appendix B Table II, Part 20 of the Code of Federal Regulations.
