This Annual Radiological Environmental Operating Report reports on the Radiological Environmental

Program, comprised of (a) the Radiological Environmental Monitoring Program (REMP),

(b) the Annual Land Use

Census, and (c) the Interlaboratory Comparison Program.

Activities in all 3 program elements are reported.

The REMP is an ongoing study conducted by Controls for Environmental Pollution, Inc.

(CEP) and Arizona State University (ASU) for Arizona Nuclear Power Project (ANPP),

Palo Verde Nuclear Generating Station (PVNGS),

The data presented in this report were obtained from samples collected by APS and ASU personnel and analyzed by CEP and ASU during 1987.

In order to determine radiation levels in the environment 'around the

PVNGS, the following types of samples were collected:

animal vegetation, human vegetation (including fruits and vegetables),

fresh milk, groundwater, drinking water, surface

ter, airborne particulate and radioiodine.

TLD's are utilized for determining environmental direct radiation levels.

Analytical results are presented and discussed along with other pertinent information.

Possible trends and anomalous results, as interpreted by CEP, are also discussed.

On July 1, 1987, Arizona State University assumed responsibi.lity for environmental analyses with the exception of vegetation, TLD, airborne particulate and airborne radioiodine samples.

Results presented are a compilation of CEP and ASU data for.

the year.

CEP data will be indicated by the letter (a) and ASU data will be indicated by the letter.

(b) throughout the Tables in this report.

TLD data are PVNGS'.

ARIZONA NUCLEAR POWER PROJECT PALO VERDE NUCLEAR GENERATING STATION OPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM This report first presents results of the operational radiological environmental monitoring program conducted during 1987 by Controls for Environmental Pollution, Inc.

(CEP) and Arizona State University (ASU) for Arizona Nuclear Power Project (ANPP), Palo Verde Nuclear Generating Station (PVNGS), followed by Interlaboratory Comparison Program results and Land Use Census results.

In compliance with federal requirements to provide a complete environmental monitoring program for nuclear reactors, and in its concern for maintaining the quality of the local environment, ANPP began its pre-operational environmental monitoring program in 1979.

The program complies with the requirements of the U.S.

Nuclear Regulatory Commission in their Reactor Assessment Branch Technical Position, Revision 1, November, 1979.

On May 25, 1985 PVNGS Unit One became operational.

The objectives of the operational radiological environmental monitoring program are as follows:

1) to determine radiation levels in the environs during reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiological impact on the environment caused by the operation of PVNGS.

A number of techniques are used to distinguish power plant effects from other sources during the operational

phase, including application of established background levels.

Operational radiation levels measured in the vicinity of ANPP are compared with the pre-operational measurements at each of the sampling locations.

Results of the monitoring program help to evaluate sources of elevated levels of radiation in the environment, e.g.,

atmospheric nuclear detonation or abnormal plant releases.

1.1.1 1.1.2 July 1, 1987

- ASU assumes responsibility for analysis of REMP samples with the exception that CEP continues analysis of vegetation and airborne particulate and radioiodine, and ANPP continues TLD analysis.

August 30, 1987

- Baisley Dairy closed down.

Samples from four other existing sample locations and one control location assure that Technical Specifications for milk sampling are met.

1.2.1 1.2.2 1.2.3 April 24, 1986

- Weekly samplings of PVNGS Reservoir (Sample Site ¹60) and Pond (Sample Site ¹59) now include collection of a sample in a glass container for Tritium analysis.

July 17, 1986

- Wedgeworth house (Sample Site ¹49) drinking water sample site changed name to Glover.

October 16, 1986

- Gavette Drinking Water sample (Sample Site

¹48) added to REMP, replacing Desert Farms.

In the spring of 1983, the Arizona State University (ASU) Radiation Measurements Facility (RMF) implemented a

long-term independent radiological environmental assessment program for the Palo Verde Nuclear Generating Station (PVNGS).

In July, 1987 the RMF was certified as a.vendor by the PVNGS Quality Assurance Department and assumed responsibility for many of the environmental assessments performed in support of PVNGS.

The data presented in this report were obtained from samples collected by PVNGS or RMF personnel during the calendar year 1987 and analyzed by RMF personnel in the RMF complex.

The assessment program consists of routine measurements of background gamma radiation and of radionuclide concentrations in media such as air, ground water, drinking water, surface water, fresh milk and vegetation.

J I

Monthly milk samples were collected from six sites until September 198 when one dairy ceased operation.

Five samples were collected thereafter.

All samples are assayed for iodine and gamma isotopic.

Weekly water samples are collected routinely from three sites.

Monthly samples are collected from three residence wells and quarterly samples are obtained from two on-site wells.

Samples are assayed for iodine-131, strontium-89, strontium-90, gross alpha, gross beta, tritium and/or gamma isotopic.

Four RMF staff members are trained and certified by PVNGS to perform routine sampling of air, surface and ground water, and milk.

Three staff members are certified by PVNGS for collection of thermoluminescent dosimeters.

2.0 ANPP has contracted with CEP and ASU to determine the ambient radiation level in the environment around PVNGS during its operation.

I The types of environmental samples collected include:

animal vegetation, human vegetation (produce and citrus fruits), groundwater, drinking water, surface water, fresh milk, airborne particulates, and radioiodine, The TLD network is managed by ANPP personnel.

TLD evaluations are conducted by the PVNGS Dosimetry Group, The locations of the monitoring sites are shown in Figure 1 and Figure 2.

The monitoring sites and the respective sample types collected are described in Table I.

Table II describes the sample collection frequency.

Information.

concerning new sample

types, locations, and collection frequency is included in these tables where applicable.

The analytical procedures discussed in this section are those routinely used by CEP to analyze samples.

3,1,1 3,1.1.1 Two liters of milk containing standardized Iodine carrier is stirred with Amberlite IRA-400 anion exchange resin for one hour.

The Iodine is stripped from the resin with sodium perchlorate (NaC10~)

and precipitated with silver nitrate (AgNO>).

The precipitate is filtered on a tared glass fiber filter.

The dried precipitate is weighed for percent recovery and counted for. Iodine-131 in a thin window, gas flow, proportional counter (Beckman Low Beta II or Berthold LB770).

These instruments have a forty-one percent efficiency and a

forty-five percent efficiency, respectively, using Iodine-131 precipitated as silver iodide (AgI) ~

3.1.1.2 The Strontium is precipitated with concentrated fuming nitric acid, redissolved in water, made basic with dilute ammonium hydroxide and precipitated as the oxalate.

The dried oxalate precipitate is counted in a low background proportional counter (Beckman Low Beta II or Berthold LB770) having sixty percent and forty-five percent Strontium-Yttrium-90 efficiencies, respectively.

The Strontium-89 activity is determined by subtracting the previously measured Strontium-90 activity and its corresponding Yttrium-90 ingrowth from the measured gross Strontium activity.

An aliquot of milk containing standardized Strontium and Yttrium carriers, is stirred with Dowex 50WX8 cation exchange resin at a pH of six for thirty minutes.

All nuclides are stripped from the resi with strong acid.

After the ingrowth period has been established, the Yttrium-90 is extracted with five percent di-2-ethylhexyl phosphoric acid (DzEHPA) in

toluene, back extracted into an aqueous

phase, precipitated as the oxalate and counted in a

low background internal gas flow proportional counter (Beckman Low Beta II or Berthold LB770) to determine the Strontium-90 content of the sample.

These systems have Strontium-Yttrium-90 efficiency of sixty percent and forty-five percent, respectively.

A suitable aliquot of sample is placed in a Marinelli beaker and counted with a

multi-channel analyzer equipped with an intrinsic Germanium detector which is coupled to a 4096 channel, computer based, multi-channel analyzer (Northern Scientific TN4500).

The resulting spectrum is analyzed by the computer, an specific

nuclides, if

present, identified and quantified.

Refer to Milk Subsection 3.1

~ 1.4.

Required on leafy vegetation only.

After appropriate preparation of the sample, analysis is performed as discussed in Subsection 3.1.1.4.

A 1.0 liter aliquot of water is evaporated to dryness and transferred to a weighed planchet:

The Gross Alpha and Gross Beta radioactivity is measured by counting the planchet in an internal gas

flow, simultaneous proportional, low background counter (Beckman Wide Beta II or Berthold LB770), or by 3.1.3.2 3.1.3 '

counting the planchet in a low background simultaneous

. counter (Tennelec LB5100).

Refer to Milk Subsection 3.1.1.4.

A 1.0 liter aliquot of the sample containing standardized stable Strontium carrier is evaporated to dryness and wet ashed with concentrated nitric acid (HNO~) and hydrogen peroxide (HzOz).

The Yttrium-90 is extracted with five percent Di-2-ethylhexyl phosphoric acid (DzEHPA) in toluene after the ingrowth period has been established, back extracted into an aqueous phase, precipitated as the oxalate and counted with an integral gas flowproportional counter (Beckman Low Beta II or Berthold LB770) having a Strontium, Yttrium-90 efficiencies of sixty percent and forty-five percent, respectively.

The counting results are back calculated to give Strontium-90 activity.

3.1.3.4 g~m Three milliliters of the water sample is mixed with Packard Opti-fluor cocktail.

The mixture used is nineteen percent sample in a non-organic cocktail.

This gives a

Tritium counting efficiency of approximately thirty percent.

The counting system used is a Beckman LS-5801 Liquid Scintillation Counter.

3.1.4.1 One liter of water containing standardized Iodine carrier is acidified with nitric acid (HNO>),

then extracted with carbon tetrachloride (CC1~) and sodium nitrite (NaNOz) to remove the Iodine.

The Iodine is back extracted from the carbon tetrachloride (CC1,)

using a

0.2% hydrazine solution which supplies more purification and an aqueous media for. precipitation.

Iodine is precipitated with silver nitrate (AgNO~)

3 '.4.2 3.1.4.3 3.1.4.4 3.1.4.5 and filtered on a tared glass fiber filter as silve iodide (AgI).

The dried precipitate is weighed for recovery and counted for Iodine-131 in a thin window, gas flow, proportional counter (Beckman Low Beta II or Berthold LB770) having forty-one percent and forty-five percent efficiencies, respectively for. Iodine-131 precipitated as silver iodide (AgI).

An aliquot of the monthly composite is taken and analyzed according to Ground and Drinking Water Subsection 3.1.3.1.

An aliquot of the monthly composite is taken and analyzed according to Milk Subsection 3.1.1.4.

An aliquot of the monthly composite is taken and analyzed according to Milk Subsection 3.1.1.2.

An aliquot of the monthly composite is taken and analyzed according to Groundwater and Drinking Water.

3.1.5.1 The Sartorius filter (cellulose nitrate filter with a

3 micron pore size), is placed in a 50 mm stainless steel planchet and counted for Gross Alpha and Gross Beta radioactivity using a low background internal gas flow, simultaneous proportional counter (Beckman Wide Beta II), or by using a low background simultaneous counter (Tennelec LB5100).

9'14-

3.1.5.2 The air filters are sealed in small, plastic Marinelli beakers and counted utilizing the method described in

'Milk Subsection 3.1.1.4.

Two analytical methods for airborne radioiodine are used by CEP depending upon the length of time between the sample collection date and the date of sample receipt at CEP.

The sensitivity of the Gamma Spectrometry Method decreases significantly after an Iodine-131 decay of greater than one half-life (8.04 days).

Therefore, if more than one week has elapsed between sample collection and analysis of the sample the Alkaline Leach Method provides a greater sensitivity and is thus the analytical method of choice.

3.1.6.1 Radioiodine is removed from activated charcoal along with a standardized iodine carrier using concentrated ammonium hydroxide (NH~OH) and hydrogen peroxide (HzOz).

The charcoal is filtered and the remaining solution is acidified with nitric acid (HNO~)

and extracted with carbon t'etrachloride (CC1~).

A 0.2%

hydrazine solution supplies further purification and an aqueous media for precipitation.

Iodine is precipitated with silver nitrate and filtered on a

tared glass fiber filter as silver iodide (Agl).

The dried precipitate is weighed for recovery and counted for Iodine-131 in'a thin window, gas flow, proportional counter (Beckman Low'eta II or Berthold LB770) having forty-one percent and forty-fivepercent efficiencies, respectively, for Iodine-131 precipitated as silver iodide (AgI).

3.2 3.1.6.2 Gamma S ectromet Method The direct gamma counting method for Iodine-131 consists of placing the charcoal canister directly on an intrinsic germanium detector and analyzing the resulting spectrum for Iodine-131 using the computer based Nuclear Data Model ND9900 System.

The system is calibrated using charcoal filters which have been uniformly loaded (in the first 5 mm) with standardized isotopes traceable to NBS.

Calibration verification is performed by analyzing a charcoal filter which has been uniformly loaded (in the first 5

mm) with standardized Iodine-131 traceable to NBS.

Deposition of activity in the first 5 mm of the filters is done to simulate actual loading.

Both standards and samples are placed on the detector so that the load gradient is decreasing with distance from the detector.

Anal tical Procedures ASU 3.2.1 Gamma S ectrosco All gamma detectors are energy calibrated weekly.

Efficiency calibrations are done annually using triplicate aliquots of mixed gamma emitting solution whose activity is explicitly traceable to the National Bureau of Standards (NBS).

Water Two liters of sample is evaporated to 500 ml and counted in a Marinelli beaker.

@ilk Milk cannot be concentrated conveniently and is counted, as

received, in a Marinelli beaker.

Soil A imal Feeds 500 ml of these types of samples is counted in a Marinelli beaker.

The Marinelli beaker geometry is volume, but the sample size is grams or kilograms.

Therefore sufficient material is uniformly packed into a volume of 500 ml to give an apparent density of 1.0 to 1.1.

9 3.2.2 3.2.3 Iodine is sorbed onto Dowex 1-X8

resin, stripped with hypochlorite, extracted into chloroform, stripped, precipitated as Pdl>,

and counted in a low background gas-flow proportional counter.

QxaxmuQ, Charcoal cartridges are counted using a Ge(Li) detector whose efficiency is determined by a standard cartridge spiked with NBS traceable mixed gamma emitter.

The activity is loaded onto the first 10% of the charcoal, and the cartridge is turned over halfway through the count.

Radiostrontium and added carrier are sorbed onto Dowex 50W-X8 and stripped with nitric acid.

Calcium is separated by repeated extractions with fuming nitric acid.

The Yttrium-90 daughter is separated and counted to determine Strontium-90.

Strontium-89 is determined by counting Strontium-89 and Strontium-90 before Yttrium-90 ingrowth and subtracting Strontium-90.

3.2.4 Radiostrontium and added carrier are precipitated from the sample as the carbonate.

The remainder of the procedure follows that for milk, beginning with nitric acid separations.

T~~

Water samples are distilled from alkaline permanganate and counted in a liquid scintillation counter.

4.0 The following sample preparation methods are routinely used by CEP.

4.1 O

1.

The plastic bags are opened and the sample weighed immediately to obtain the wet weight.

2.

After weighing, the sample is transferred to a drying pan and placed in an oven at 110 C.

3.

The dry sample is ground to a fine powder and homogenized.

4.

The sample is then dissolved or ashed, whichever is required for further isotopic analysis.

4.2 Iodine carrier (Potassium Iodide),

formalin and sodium bisulfate are added when the milk is collected to stabilize the Iodine-131 during shipment of samples to CEP.

The procedure for Fresh Milk is then followed as described in Section 3.1.1 of this report.

The system has a tritium counting efficiency of sixty percent on an unquenched sample.

The Gross Alpha Counting Systems consist of two windowless gas flow detectors manufactured by Nuclear Measurements Corporatio with an Alpha efficiency of 55% with a background of less than O.l cpm.

The Low Background Scintillation Counter consists of a Zinc Sulfide screen.

The system has an average Alpha background of 0.1 cpm.

The RMF has. improved the automatic quench compensation feature through a modification which adds a quench correction for background.

6.0 6.1 Analytical detection limits are governed by a

number of factors including:

6.1.2 6.1.3 6.1.4 The sample size taken is based on the numerical data one wishes to obtain which can describe a particular situation and can be interpreted as a basis for possible action.

The sample size has to be representative to provide for accurate analysis or the entire process is invalid (Table III).

The fundamental quality in the measurement of a radioactive substance is the number of disintegrations per unit time.

As with most physical measurements in analytical chemistry, it is seldom possible to make an absolute measurement of the disintegration rate but rather. it is necessary to compare the sample with one or more standards.

The standards determine the counter efficiency which may then be used to convert sampl counts per minute (cpm) to disintegrations per minute (dpm).

Any counter will show a certain counting rate without a sample in position. This background counting rate comes from several sources:

1) natural environmental radiation from the surroundings; 2) cosmic radiation; and 3) the natural radioactivity in the counter material itself.

The background counting rate will depend on the amount of these types of radiation and the sensitivity of the counter to the radiation.

The amount of time devoted to counting background depends on the level of activity being measured.

In general, with low level samples, this time should be about equal to that devoted to counting a sample (Table IV).

Decay measurements are useful in identifying certain short-lived isotopes.

The disintegration constant, or its related

quantity, the half-life, is one of the basic characteristics of a specific radionuclide and is readily determined if the half-life is sufficiently short.

Most radiochemical analyses are carried out in such a way that losses occur during the separations.

These losses occur due to a large number of contaminants that may be present and interfere during chemical separations.

Thus it is necessary to include a

technique for estimating these losses in the development of the analytical procedure.

The Lower Limits of Detection are calculated using the following formula:

2.22 Number of disintegrations per minute per picocurie.

Y Fractional radiochemical yield (when applicable).

Radioactive decay constant for the particular radioisotope.

Elapsed time between sample collection (or end of the sample collection period) and time of counting.

used in the calculation of the LLD for a

particular measurement system is based on the actual observed variance of the background counting rate, or, of the counting rate of the blank sample (as appropriate),

rather than on an unverified theoretically predicted variance.

In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background included the typical contributions of other nuclides normally present in the samples.

The activities per unit sample mass or volume are determined using the following formula:

8.0 I

Data Inte retation and Conclusions Interpretations and conclusions regarding all types of samples analyzed during 1987 are discussed in the following sections.

Assessment of pre-operational and operational data revealed no significant changes to environmental radiation levels.

There was no observed impact on the environment due to PVNGS operations.

8.1 Air Particulates Airparticulate samples were collected from each of the twelve monitoring sites on a weekly basis during 1987.

The twelve sites are 1A, 4A, 6A, 7A, 14A, 15A, 17A, 21A, 29A, 35A, 40A and 44A.

6A is the control site.

Air filters were analyzed for Gross Alpha and Gross Beta activities.

Gamma Spectral analysis of the air filters was done on the individual filters for Stations

14A, 15A,

17A, 21A, 29A and 40A due to the Salt DriftMonitoring Program.

Gamma Spectral analysis for the other stations was performed on quarterly composites by station.

Thirty-four air particulate samples were invalid.

The samples and the reason for the statuses are listed below:

Station 6A showed the highest activity during the quarter (0.047 i0.002 pCi/m~) collected 01/07/87.

Station 6A showed the lowest activity (0.012 20.002 pCi/m~)

collected on 02/18/87.

Weekly mean activities ranged from a low of 0.014 i0.002 pCi/m~ during the week of 02/ll/87-02/18/87 to a high of 0.043 i0.002 pCi/m~ in the week of 12/30/86-01/07/87.

The range of results is comparable to previous quarterly data and does not indicate any anomalies.

Table VIIIpresents second quarter Gross Beta results.

Several stations showed the highest activity during the quarter of 0.031 i0.002 pCi/m~.

The Station 6A sample collected 06/10/87-06/17/87 showed the lowest level at 0.017 20.002 pCi/m~.

Weekly mean activities ranged from a low of 0.020 pCi/m~ during the periods of 04/Ol/87-04/08/87 and 06/10/87-06/17/87 to a high of 0.029 20.001 pCi/m~ in the weeks of 05/13/87-05/20/87 and 05/27/87-06/03/87.

The range of results is comparable t previous quarterly data and does not indicate any anomalies.

Table IX presents the Gross Beta levels during the third quarter of 1987.

The lowest value of 0.015 20.002 pCi/m~ was observed at station 44A collected during the week of 08/11/87-08/18/87.

The hi,ghest level of activity was 0.040 20.002 pCi/m~ at Station 29A during the collection period of 09/15/87-09/22/87.

Weekly mean activities ranged from a

minimum of 0.018

+0.002 pCi/m~ (08/ll/87-08/18/87),

to a

maximum of 0.037 20.002 pCi/m in the period of 09/15/87-09/22/87.

The range of results is comparable to pervious quarterly data and does not indicate any anomalies.

Table X presents the Gross Beta activities seen in the fourth quarter.

Observed levels varied from 0.016 i0.002 pCi/m~ at Station 40A (collected ll/03/87-11/10/87), to 0.055 i0.003 pCi/ms at several stations collected on 11/24/87-12/Ol/87.

Weekly mean activities ranged from 0.019 20.002 pCi/m~ during the collection period of 11/03/87-11/10/87 to 0.050 XO.OO collected 11/24/87-12/01/87.

Based on data from other nuclear reactor environmental monitoring programs, the trend for.

Gross Beta in air particulates for the PVNGS during the fourth quarter of 1987 is similar to those for other reactor sites located west of the Mississippi River.

Table XI contains the mean Gross Beta activities by station.

Mean quarterly activities are calculated using all weekly activities except those marked invalid.

Mean activities for each quarter ranged from a low of 0.024 i0.006 at several stations during the year, to a high of 0.038 20.009. pCi/m at Station 21A in the fourth quarter.

The average Gross Beta activity for each quarter is as follows:

First Quarter 1987 Second Quarter 1987 Third Quarter 1987 Fourth Quarter 1987 0.028 +0.001 0.025

%0.001 0.026 20.001 0.034 t0.003 No man-made Gamma-emitting nuclides were detected in any of the air filter samples collected during 1987.

Tables XII thru XV show the Gross Alpha activity for each week during 1987.

Gross Alpha activity was detected in five samples collected in 1987.

These data are consistent with the activity seen during preoperational monitoring.

PreoperatIonal Operational Chernobyl 85 YEAR

8.2 Airborne Radioiodine I

Samples for airborne radioiodine monitoring are collected concurrently with the air particulate samples.

These samples are collected in charcoal cartridges and analyzed for Iodine-131.

Station 6A is the control site.

As can be seen in Table XVI one radioiodine sample collected during the first quarter of 1987 indicated detectable Iodine-131 activity (at Sample Station 40A).

Theisecond quarter of 1987 (Table XVII) two samples indicated detectable Iodine-131 activity (Stations 6A and 35A).

Third quarter radioiodine data may be found in Table XVIII.

One sample at Station 4A indicated Iodine-131 activity above the detection limit of 0.007 pCi/m~.

As can be seen in Table XIX six samples collected during the fourth quarter of 1987 indicated detectable Iodine-131 activity.

These samples were analyzed by chemical separation of iodine, followed by gross beta counting.

Verification of the indicated iodine-131 activity was subsequently performed by additional gross beta counting for half-life analysis, rather than by gamma spectrometry.

8.4 Human vegetation samples were collected from four local farms since no commercial companies were located in the area.

The leafy vegetation samples collected during 1987 included:

mustard greens and lettuce.

The citrus samples included grapefruits,

oranges, tangerines and lemons.

The four sample locations were ¹47, 51, 52 and 61.

Location 61 is the control.

Samples were collected monthly during the growing season, as available.

Table XXIV presents Iodine-131 data for the human vegetation samples collected during 1987.

No observable activity was detected in any of the samples.

The results of the Gamma Spectral analyses for. all human vegetation samples is presented in Tables XXV and XXVI.

No man-made Gamma emitting nuclides were detected in any of the samples.

Animal vegetation samples were collected from six local farms participating in the milk survey.

Types of vegetation collected included:

grain, hay, haylage and silage.

These samples were analyzed for Strontium-89, Strontium-90 and Gamma emitting nuclides.

The six sample locations were ¹50, 51, 53, 54, 55 and 56.

Table XXVII indicates no Strontium-89/90 was detected in 1987.

One hay sample collected on 02/13/87 from the Skousen Dairy (sample location

¹54) indicated Cesium-137 activity of 199 +38 pCi/kg.

No other Gamma emitting nuclides were detected (Table XXVIII).

8.5 Drinkin Water Drinking water samples were taken monthly.

The samples were analyzed for Gross

Alpha, Gross

Beta, Strontium-90, Tritium and for Gamma-emitting nuclides.

Results of these analyses are summarized in Tables XXIX and XXX.

The sample locations were ¹46, 48 and 49.

Twenty-one (21) of the samples showed Gross Alpha activity above the detection limit of 1.0 pCi/1.

The range of 'Gross Alpha activity in drinking water samples collected during 1987 was from less than 1

~ 0 pCi/1 to 7.6 pCi/1 (Glover Residence, Site ¹49, collected 07/14/87).

Gross Beta activity ranged from less than 2.0 pCi/1 to a high of 10.0 20.8 pCi/1 (McArthur Residence, Site ¹46, collected 03/12/87).

Strontium-90 was not detected above 0.8 pCi/1 in any of the drinking water samples collected during 1987.

Tritium results, for all drinking water samples collected during 1987, were less than 1340 pCi/l.

In addition, no Gamma-emitting nuclides of man-made origin were detected in any of the samples.

8.6 Groundwater Ill Quarterly groundwater samples were collected from the on-site wells (Well 27ddc and Well

34abb, Sample Sites

¹57 and 58, respectively).

Groundwater samples were analyzed for Gross Alpha, Gross Beta, Strontium-90, Tritium and for Gamma-emitting nuclides.

Results obtained from the analysis of the samples are presented in Tables XXXI and XXXII.

Both groundwater samples collected on 11/10/87 analyzed positive for Gross Alpha activity.

Gross Beta activity was detected in two of the groundwater samples collected during 1987:

Well 27ddc, 4.6 i5.7 pCi/1 (08/11/87) and Well

34abb, 3.0 k7.7 pCi/1 (08/ll/87); these are sample sites

¹57 and 58, respectively.

No groundwater sample collected during 1987 had detectable levels Strontium-90.

In addition, no isotopes of interest were detected Gamma Spectral analysis of the groundwater samples.

8.7 Surface Water Surface water samples were introduced into the monitoring program during the third quarter of 1982.

Samples from PVNGS Reservoir (Sample Site

¹60) and PVNGS Evaporation Pond (Sample Site ¹59) were collected weekly throughout 1987.

These samples were analyzed for Iodine-131, Gross

Alpha, Gross

Beta, Strontium-89, Strontium-90, Tritium and Gamma-emitting nuclides.

Results of these analyses are presented in Tables XXXIIIthrough XXXVI.

Iodine-131 was detected in forty-eight of the 1987 surface water samples collected, Activity ranged from less than 0.5 pCi/1 to a high of 25.0 i3.0 pCi/1 on 08/25/87 at the PVNGS Reservoir (Sample Site ¹60).

PVNGS Reservoir samples demonstrated Gross Beta activities ranging from 3.4 +0.5 pCi/1 (a monthly composite sample) to 21 +2 pCi/1 (12/29/87).

The samples from the PVNGS Evaporation Pond (Sample Site ¹59) showed Gross Beta activities ranging from 8.0 20.6 pCi/1 (a monthly composite sample) to 270 i10 pCi/1 (09/22/87).

PVNGS Reservoir and PVNGS Evaporation Pond samples demonstrated strontium

-90 activity ranging from less than 0.5 pCi/1 to 1.4 pCi/1.

Strontium-89 results ranged from less than 1 pCi/1 to 3.1 pCi/l.

h Gamma Spectral analysis of the samples showed no detectable activity for Gamma emitting nuclides of interest except Iodine-131 (Table XXXVI).

-111-

The surface water samples were analyzed for Tritium activity.

The PVNGS Reservoir (Sample Site ¹60) sample results were all less than LLD.

The PVNGS Evaporation Pond (Sample Site ¹59) sample results demonstrated Tritium activity throughout most of 1987.

8.8 Fresh milk samples were collected on a monthly basis during 1987 from the following locations:

1.

Al Lueck, Jr. Dairy (Sample Site ¹55) 2.

Cordell Baisley Dairy (closed 08/30/87)

(Sample Site ¹50) 3.

Butler Dairy (Sample Site ¹51) 4.

John Kerr Dairy (Sample Site ¹53) 5.

Hamstra ¹2 (designated operational control location)

(Sample Site

¹56) 6.

Paul Skousen Dairy (Sample Site ¹54)

Milk samples were analyzed for Iodine-131, Strontium-89, Strontium-90 and Gamma-emitting nuclides.

Results of these analyses are presented in Tables XXXVIIand XXXVIII. Site ¹56 is the control.

Analytic method involved radiochemical separation, followed by gas flow beta proportional counting.

Iodine-131 analyses of the milk samples showed positive results in two of the samples.

Activity was detected on 05/15/87 samples from the Al Lueck, Jr.

Dairy (2.6 +0.7 pCi/1) and the Cordell Baisley Dairy (2.4

+0.7 pCi/1)

(Sample Sites ¹55 and 50, respectively).

Sample Site ¹55 again yielded activity on 07/20/87, but below 1 pCi/liter.

None of the milk samples were positive for Strontium-89 or -90.

Milksamples gave no positive results for gamma-emitting nuclides, except that Iodine-131 was detected in a 09/21/87 sample from Hamstra ¹2 Dairy (Sample Site ¹56) via gamma spectral analysis.

Radiochemical analysis of the same sample determined Iodine-131 to be (0.96 pCi/1, via gas flow beta proportional counting--the analytical method used to generate the data in Table XXXVII.

Radiochemical analysis of iodine-131 to be <0.96 pCi/l.

yielded only one, Hamstra ¹2 in which any gamma isotope this instance, the iodine-131 close to the lower limit of the same sample determined Three of the 68 milk samples analyzed radiochemically contained iodine-131 above the lower limit of detection.

Mean values of Iodine-131 in the evaporation pond and the reservoir were 2.1 pCi/1 and 6.0 pCi/1, respectively.

Gross alpha and beta analyses were performed on 110 surface water, ground water and drinking water samples.

All ground water and drinking water samples were within the natural backgrounds found in the area.

The gross beta activity in the evaporation pond (Sample Site ¹59) was approximately ten times greater than that measured in the reservoir (Sample Site ¹60).

Strontium-90 analyses were performed on 110 surface water, ground water and drinking water samples.

Except for certain indications of strontium-90 in drinking water and surface water, all results were less than the lower limits of detection for the specific measurements.

The indications of strontium-90 were <1.4 pCi/1 in all instances.

Strontium-89 analyses were performed on 66 surface water samples.

Except for one result of 0.52 pCi/liter, all results were less than the lower limits of detection for the specific measurements.

The indications of strontium-89 were typically less than 1 pCi/liter; the maximum indication was <3.1 pCi/liter.

Allof the 36 milk samples assayed for strontium-89 and strontium-90 were below the lower limits of detection.

- 1.33 The USNRC sample was supplied in a plastic bottle.

Tritium will undergo isotope exchange in plastics, resulting in low results.

The sample was over five months old when received by the RMF.

The strontium calculations were repeated and no computational errors were found.

The samples results which were originally reported by the RMF were averages of duplicate measurements.

Therefore, precision is not a factor.

The RMF has reviewed the sample procedures and analysis and can find no explanation for the discrepancy.

The results are consistent and in excellent agreement with spiked canister.

The RMF calibrates the Ge(Li) detectors by averaging three spiked canisters.

The canisters are spiked with Xodine-131 standards, traceable to the National Bureau of Standards, over the first 10% of the charcoal.

In accordance with PVNGS Technical Specification 3/4.12.2, the annual Land Use Census within a five mile radius of mid line PVNGS Unit 2 containment was performed during December 1987 by Ralph B. Ochoa and Carolyn Persson.

Observations were made in each of the 16 meteorological sectors of the nearest milking animals (cows and goats),

nearest residence, and the nearest garden of greater than 500 ft~ producing broad leaf vegetation.

This census was completed by driving the roads within a five mile radius of PVNGS noting the location of the above mentioned items.

The results of the Land Use Census are presented in Table 1 and discussed below.

In the table, the radial direction and mileage from Unit 2 containment are presented for each location.

The radial direction is one of the'6 different compass points.

The mileage was estimated from the map position of each location.

2.0 2.1 2.2 Table 1 presents the location of the nearest resident to the PVNGS in each of the 16 meteorological sectors.

There were two changes in the nearest resident status noted in the 1987 census.

These changes were in the east northeast and the south sectors.

Milk goats were located within the five mile radius of Unit 2 during the 1986 Land Use Census.

During the 1987 Land Use Census, three milk goats were located in the East Northeast Sector 4.75 miles from PVNGS Unit 2

Containment.

Milk was obtained for radiological analysis in February, 1987.

Since the dose commitment was LLD, it was not 20% greater than at a location from which samples are currently being obtained in accordance with Specification 3.12.1.

Therefore, the new location identified in the 1986 Land Use Census was not added to the radiological environmental monitoring program for 1987.

2.3 No gardens greater than 500 square feet producing broad leaf vegetation were found during the 1987 Land Use Census.

2.4 No changes were made to the REMP as a result of the 1987 Land Use Census.
