Abstract The operational radiological environmental monitoring program is an ongoing study conducted by the Radiation Measurements Facility at Arizona State University for the Palo Verde Nuclear Generating Station.

~f I U

During 1989, samples were collected by the Palo Verde Nuclear Generating Station and Radiation Measurements Facility personnel. The following categories of samples were collected:

broad leaf vegetation, fresh milk, groundwater, drinking water, surface water, airborne particulate and radioiodine, and sludge.

Thermoluminescent dosimeters were used to measure environmental gamma radiation.

All assays were performed by the Radiation Measurements Facility.

Thermoluminescent dosimeters were issued and processed by the Palo Verde Nuclear Generating Station. Sludge and Water Reclamation Facility input water samples were collected by personnel from the Palo Verde Nuclear Generating Station.

OPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 1.0 Introduction The Radiological Environmental Monitoring Program (REMP) was established r,

for the Palo Verde Nuclear"Generating Station (PVNGS) by the Arizona Nuclear Power Project (ANPP) in 1979. The program complies with federal requirements set forth by the U.S. Nuclear Regulatory Commission (U.S.

NRC) to provide a complete environmental monitoring program for nuclear reactors. This report contains the measurements and findings for 1989.

P All bracketed numbers refer to references contained in section 12.

The objectives of the radiological environmental monitoring program are as follows: 1) to determine baseline radiation levels in the environs prior to plant operation and to compare the findings with measurements obtained during reactor operations; 2) to monitor potential critical pathways of radio-effluent to man; and 3) to determine radiological impacts on the environment caused by the operation of PVNGS.

Results from the REMP help to evaluate sources of elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations or abnormal plant releases.

Results for the PVNGS pre-operational environmental monitoring program are presented in references 1-5.

The initial criticality of Unit One occurred May 25, 1985. Initial criticality for Units Two and Three were April 18, 1986 and October 25, 1987, respectively. PVNGS operational findings are presented in references 6-8. The Radiation Measurements Facility (RMF) radiological assessments for 1987 and 1988 are found in references 9 and 10.

This report contains the measurements and findings for 1989. All bracketed numbers refer to references contained in section 12 of this report.

2.0 Descri tion of the Monitorin Pro ram The pre-operational'.radiological environmental monitoring, program, which began in 1979, was performed by PVNGS and outside organizations. These organizations continued the, program into the operational phase of PVNGS.

In 1988, the RMF assumed responsibility for sample collection, assay, and data processing and the REMP annual report. TLD measurements, collection of sludge, water influent samples, and the land use census are conducted by PVNGS personnel.

2.1 The ASU Radiation Measurements Facilit In the spring of 1983, the RMF implemented a long-term independent radiological environmental assessment program for the PVNGS.

In July 1987, the RMF was certified as a vendor by the APS Vendor Quality Program and assumed responsibility for many of the environmental assessments performed in support of the nuclear power station.

RMF staff are trained and certified to perform routine sampling of air, surface and ground water, drinking water, milk and vegetation. In accordance with the RMF Quality Assurance Program, all samples are collected using PVNGS procedures and analyzed using written and approved RMF procedures. Annual audits of the program are conducted by the APS Vendor Quality Organization.

To provide the highest quality results, the RMF participates in radiochemistry intercomparison programs with the United States Environmental Protection Agency (USEPA) and the Canadian Department of Health and Welfare, Bureau of Radiation and Medical Devices (BRMD).

2.2 1989 PVNGS Radiolo ical Monitorin Pro ram The assessment program consists of routine measurements of background gamma radiation and of radionuclide concentrations in media such as air, groundwater, drinking water, surface water, fresh milk, vegetation, and sludge.

Samples were collected by PVNGS or RMF personnel-at the monitoring sites shown in Figures 2.1 and 2.2.. The specific sample types, sampling locations, and sampling frequencies as set forth in Palo Verde Nuclear Generating Station Technical Specifications [11] are presented in Tables 2.1 and 2.2. Other samples not required by reference ll were processed in accordance with contractual obligations or written requests from PVNGS.

Background gamma radiation measurements are performed using thermoluminescent dosimetry at fifty locations by PVNGS.

2.3 Radiolo ical Monitorin Pro ram Chan es for 1990 2.3.1 In January 1989, bi-weekly composites of weekly grab samples commenced for drinking water.

2.3.2 In March 1989, gross beta analysis was changed to quarterly for surface water.

2.3.3 In April 1989, four corner composite sampling commenced on the evaporation ponds.

2.3.4 In June 1989, the day of the week that water sample collection took place changed from Wednesday to Tuesday.

Sr-90 was not required on residence wells. Gross 'beta, Sr-90, and I-131 analysis were not required for on-site wells.

Gross beta was no longer required on Water Reclamation Facility influent samples.

3.0 Sam le Collection Pro ram 3.1 Water samples were collected by RMF and WRF personnel using PVNGS procedures.

3.1.1 Weekly samples were collected from the Reservoir, the Evaporation Pond ¹1, and Evaporation Pond ¹2. Weekly samples were collected in 1-gallon cubitainers and 500-mL glass bottles at all three sites. Cubitainer samples were acidified with HCl in the laboratory prior to analysis.

3.1.2 Monthly composited samples were collected at four residence, wells. Monthly composited samples were collected in 500 mL glass bottles and in one gallon cubitainers for the semi-monthly samples. Samples were collected in 1-gallon cubitainers and acidified with HC1 in the laboratory prior to analysis.

3.1.3 Quarterly grab samples were obtained from on-site wells 34abb and 27ddc. Samples were collected in 1-gallon cubitainers and 500-mL glass bottles. Cubitainer samples were acidified with HC1 in the laboratory prior to analysis.

3.2 Ve etation soil Vegetation samples were collected by RMF personnel using PVNGS procedures.

4.0 Anal tical Procedures A summary of RMF methods is presented here. Sample sizes are provided in Table 4.1. Typical times between sample collection and counting are presented in Table 4.2. Typical counting efficiencies and radiochemical yields are presented in Table 4.3. Table 4.4 presents typical sample counting times. The sample size and counting times used for LLD calculations are the same as used for actual measurements.

4.1 Gamma S ectrometr All gamma spectra are obtained from Ge(Li) or HPGe detectors.

Efficiency calibrations are done annually, and in triplicate, for each geometry used. The calculations are performed with a solution of mixed gamma ray emitters whose activities are explicitly traceable to the U.S. National Institute of Standards and Technology.

4.1.1 Water Samples are counted in a 500-mL Marinelli beaker. To reduce the counting time, up to 2 liters may be evaporated to 500 mL and counted.

4.1.2 Milk Milk is counted as received, in a 500 mL Marinelli beaker.

4.1.3 Soil Animal Feeds Ve etation 300 g of material is mixed with 200 mL of water and homogenized in a blender. The sample is then transferred to a 500-mL Marinelli beaker and counted.

4.1.4 Air Particulate Filters Filters are counted as received. Monthly composites consist of 4-5 filters stacked on the detector and counted.

4.1.5 Charcoal Canisters Charcoal canisters are counted on a twin NaI detector system. Gamma spectroscopy is used only for verification if I-131 is detected by NaI. Counting efficiency is determined by spiking blank canisters with I-131 traceable to the National Institute of Standards and Technology (NIST). A

canister spiked with Ba-133 is used to verify system performance prior to counting each week's samples.

4.1.6 ~Slud e Sludge was packed uniformly in a Marinelli beaker and counted.

4.2 Gross Beta Activit 4.2.1 Water Samples are evaporated to dryness in stainless steel planchettes (after preliminary evaporation and conversion to nitrates).

4.2.2 Air Particulate Filters Efficiency calibration is obtained by depositing a known amount of NIST traceable Sr-90 on the surface of a glass fiber filter whose surface has been sealed to prevent penetration of the activity into the filter medium. Samples are counted as received after allowing 10 days for decay of radium and thorium daughters.

4.3 Tritium 4.3.1 Water Water samples are distilled from alkaline permanganate and counted in a liquid scintillation counter. Efficiency is determined on samples with identical quench and sample scintillant ratios.

4.4 Iodine-131 4.4.1 Water Radioiodine and added carrier are oxidized to I2 and extracted into chloroform, reduced and back-extracted into aqueous bisulfite, precipitated as PdI2, and counted in a low-background counter. Counting efficiency is corrected for self-absorption by adding a known amount of I-131 traceable to NIST standard to a series of samples having

varying amounts of iodide, precipitating as Pd12, and counting in a low-background counter.

4.4.2 Milk Radioiodine and added carrier are adsorbed onto Dowex 1-X8 resin, stripped with hypochlorite, extracted into chloroform and determination completed as for water samples.

4.5 Strontium-89 and Strontium-90 Radiostrontium and added carrier are precipitated from the samples as carbonates. Calcium and other elements are separated by repeated extractions with fuming nitric acid. The sample is counted immediately after separation from the Y-90 daughter of Sr-

90. This gives the total activity due to Sr-89 and Sr-90. After a 14-day ingrowth the sample is counted again. The increase in count rate is due to Y-90, which at equilibrium is equal to Sr-90, whose activity is subtracted from the initial count to determine Sr-90. Counting efficiencies are corrected for self-absorption by adding a known amount of respective NIST traceable nuclide to a series of samples containing varying amounts of the respective carrier, precipitating as carbonate, and counting in a low-background counter.

5.0 Nuclear Instrumentation 5.1 Detectors and E ui ment Gamma spectra are analyzed by a Canberra Series 95 Multichannel Analyzer (MCA) using a MicroVax computer. Three Detectors are available:

1) PGT Ge(Li), 26% efficiency, 1.90 keV FWHM Q 1332.5 keV

2) Canberra Ge(Li), 14% efficiency, 2.08 keV FWHM Q 1332.5 keV

3) ORTEC HPGe, 13% efficiency, 1.98 keV FWHM Q 1332.5 keV Two Tennelec LB-5100 low background proportional counters are used for alpha and beta counting. Each system has been interfaced to a personal computer and is completely automatic. Sample results and background counts are stored on disk. In addition, the computer is able to produce control charts and voltage plateaus.

Liquid scintillation counting is done in a Beckman LS-1801 Liquid Scintillation Spectrometer.

6.0 Isoto ic Detection Limits and Re ortin Criteria 6.1 Lower Limits of Detection The lower limits of detection (LLD) and the method for calculation are specified in the PVNGS Technical Specifications [11] and are presented in Table 6.1. RMF a priori LLDs are presented in Table 6.2.

6.2 Data Re ortin Criteria All results which are less than the Technical Specifications defined LLD, but greater than the a posteriori LLD are reported at the amount of activity determined and its respective error.

Errors are presented as + 1 o.

20 Occasionally the PVNGS Technical Specifications a priori LLDs [11) may not be achieved as a result of; background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, self absorption corrections, decay corrections for short half-lived radionuclides, or other uncontrollable circumstances.

In these instances, the contributing factors will be noted in the table where the data is presented.

26 8.0 Results and Data Inter retation Results and interpretation of the data for all of the samples analyzed during 1989 are presented in the following sections. Assessment of pre-operational and operational data revealed no significant changes radiation levels. There was no observed impact on the to'nvironmental environment due to PVNGS operations in 1989.

8.1 Air Particulates Weekly gross beta results in quarterly format, are presented in Tables 8.1 through 8.4. Table 8.5 contains the average gross beta activities by station. Average quarterly activities are calculated using all weekly activities except those marked invalid. The findings are consistent with pre-operational and previous operational results. 'aseline 8.2 Airborne Radioiodine Tables 8.7 through 8.10 present the quarterly radioiodine results.

No radioiodine was detected in any of the samples.

8.3 V~e etation Table 8.11 presents I-131, Cs-134 and Cs-137 data for the vegetation samples. No activity was observed in any of the samples.

8.4 Drinkin Water All samples we'e analyzed for I-131 (radiochemical), Gross Beta, I

Sr-90, H-3, and for gamma-emitting nuclides. Results of these analysis are summarized in Tables 8.12 and 8.13.

Gross Beta activity ranged from less than 2.7 pCi/L to a high of 11.6 pCi/L (Shepard Residence 10/31/89). A trace amount of Sr-90 was detected at the Scott residence (3/15/89). Tritium results were less than LLD for all drinking water samples. No gamma-emitting nuclides of man-made origin were detected. All I-131 results were less than LLD.

27 8.5 Groundwater All groundwater samples were analyzed for Gross Beta, Sr-90, H-3, I-131 and for gamma-emitting nuclides. Results obtained from the analysis of the samples are presented in Table 8.14.

Gross Beta results were consistent with pre-operational and prior operational measurements. No radioactivity was observed above the LLD values for I-131, Sr-90, H-3 or gamma spectrometry.

8.6 Surface Water Surface water samples from the Reservoir and Evaporation ponds were analyzed for Gr'oss Beta, Sr-89, Sr-90, H-3 and gamma-emitting nuclides. Results are presented in Tables 8.15 through 8.17. I-131 was observed in the Reservoir and Evaporation Pond ¹1. The highest concentration was 25.8 pCi/L (02/14/89) in the Reservoir and 23.2 pCi/L in Evaporation Pond ¹1.

Influent samples were collected from the Water Reclamation Facility (WRF) and analyzed for gamma emitting nuclides, H-3, and Gross Beta activity. The results, presented in Table 8.19, indicate that I-131 was observed routinely. The highest concentration was 55.5 pCi/L (08/15/89). The results are consistent with assays from the previous year.

Gamma spectrometry analysis was performed on samples obtained from each of the three cooling towers and results are presented in Tables 8.20 through 8.22. Iodine-131 was routinely measured in the cooling towers of operating units. The highest concentration was 132 pCi/L (02/14/89), 142 pCi/L (02/14/89) and 164pCi/L (02/21/89) for Units ¹1, ¹2, and ¹3 respectively. A trace amount of Cs-137 was detected in Unit ¹1 (02/21/89).

Elevated I-131 levels in the cooling towers are not the result of plant effluents, but instead reflect the increased concentration observed in the WRF influent. The WRF influent I-131 is a result of radiopharmicudical discharges into the Phoenix sewage system, not the result of PVNGS effluents. Refer to Section 11 of the 1988 AREOR for a detailed explanation.

28 Water samples from the Retention Basins were analyzed for Tritium and by gamma spectrometry. The results, presented in Tables 8.23 and 8.24, indicate that Cs-134, Cs-137, and I-131 concentrations were above LLD in a few of the samples collected during the first four months of the year. Cs-137 was noted again in the 09/26/89 sample obtained from Retention Basin ¹2. Cr-51 was observed in the sample obtained from Retention Basin ¹2 on 02/21/89. Tritium concentrations in both Retention Basins were elevated at the end of 1988 and the maximum concentrations for 1989 were recorded on the first sample collection of 1989. Tritium concentrations decreased thereafter.

Table 8.25 presents gamma spectrometry measurements of samples collected from Sedimentation Basin ¹2 (J-Hook Pond). No man-made gamma-emitting radionuclides were observed.

8.7 Milk Fresh Milk samples were analyzed by gamma spectrometry for Cs-134, Cs-137, Ba-140, and La-140. Samples were analyzed radiochemically for I-131. As shown in Table 8.18 all of the results were < LLD.

8.8 ~Slud e Sludge samples were obtained from several on-site locations and analyzed by gamma spectrometry. Results can be found in Table 8.26. During the year, crace amounts of Cs-137 were detected in Sedimentation Basin ¹2 (J-Hook Pond) and a trace of Mn-54 was observed once (09/05/89). Various radionuclides, including Co-60, Cs-137, Mn-54 and Sb-125 were observed in the Retention Basins.

Iodine-131 was measured in the Waste Centrifuge from the WRF. No activity was observed in the STP Digestor. Small concentrations of Co-60, Cs-137 and Mn-54 were noted in Evaporation Pond ¹2.

82 10.0 Land Use Census

10. 1 Introduct'o In accordance with PVNGS Technical Specifications 3.12.2, the annual Land Use Census within a five mile radius of mid-line PVNGS Unit 2 containment was performed during October 1989.

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 square feet 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 10.1 and discussed below. In the table, the radial direction and mileage from Unit 2 containment are presented for each location. The mileage was estimated from map position from each location.

Improved estimates in distance and direction have resulted in slightly different distances as compared to the 1988 AREOR.

Unless otherwise stated, the actual location is the same as stated in the 1988 AREOR.

10.2 Census Results 10.2.1 Nearest Resident There were five changes in the nearest resident status noted in the 1989 census. These changes were in the E, SE, SSE, WSW and NW sectors.

I 10.2.2 Milkin Animals Milk goats were located in the East Northeast sector within the five mile radius of Unit 2 during the 1988 and again during the 1989 Land Use Census. This location is not a commercial milking operation and was not added to the REMP due to unavailability of regular samples.

85 11.0 Summar and Conclusions The conclusions are based on a review of the radioassay results and background gamma radiation measurements for the 1989 calendar year.

The radioassay conclusions are based on observations of fission product radionuclides and do not include observations of naturally occurring, radionuclides such as the uranium or thorium series, C-14, or K-40.

A summary of all sample results for 1989 is presented in Table 11.1.

With the exception of on-site surface water and associated sludge, all sample assays presented in the annual report reveal no detectable man-made radioactivity which can be attributed to PVNGS. As reported in 1988 [10], I-131 concentrations in the Reservoir and Evaporation Ponds are the result of off-site sources and appear in the effluent sewage from Phoenix.

Natural background radiation is consistent with measurements reported in previous pre-operational and operational radiological environmental e monitoring program annual reports. [1-10)

13.2 In the 1988 AREOR, Tables 8.6 and 8.7 (pages 37 and 38) reported a Lower Limit of Detection of 0.07 pCi/m . The correct value is 0.007 pCi/m .

13.3 In the 1988 AREOR, Table 10.1 (page 85) listed a milk goat at 4.75 miles in the NE sector. This should have read the ENE sector.

The NE sector goat should be "None".

Abstract the radiological environmental monitoring program is an ongoing study conducted by the Radiation Measurements Feei lity at Arizona State University for the Palo Verde Nuclear Generating Station.

During 1990, samples were collected by the Palo Verde Nuclear Generating Station and Radiation Measurements Facility personnel. The following categories of samples were collected:

broad leaf vegetation, fresh milk, groundwater, drinking water, surface water, airborne particulate and radioiodine, and sludge.

Thermoluninescent dosimeters were used to measure enviroanental ganma radiation.

All assays were performed by the Radiation Measurements Facility. Thermoluminescent dosimeters were issued and processed by the Palo Verde Nuclear Generating Station. Sludge and Water Reclamation Facility influent water samples were collected by personnel from. the Palo Verde Nuclear Generating Station.

OPERAT IOHAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 1.0 Introduction The Radiological Envirormental Monitoring Program (REMP) was established for the Palo Verde Nuclear Generating Station (PVHGS) by the Arizona Nuclear Power Project (ANPP) in 1979. The program complies with federal requirements set forth by the U.S. Nuclear Regulatory Coaeission (U.S. NRC) to provide a complete envirowentai monitoring program for nuclear reactors. This report contains the measurements and findings for 1990. All bracketed nunbers refer to references contained in section 12.

The objectives of the radiological enviroanental monitoring program are as follows: 1) to determine baseline radiation levels in the environs prior to plant operation and to compare the findings with measurements obtained during reactor operations; 2) to monitor potential critical pathways of radio-effluent to man; and 3) to determine radiological impacts on the enviroanent caused by the operation of PVHGS.

Results from the REMP help to evaluate sources of elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations or abnormal plant releases.

Results for the PVNGS pre-operational environnentai monitoring program are presented in references 1-5.

The initial criticality of Unit One occurred May 25, 1985. Initial criticality for Units Two and Three were April 18, 1986 and October 25, 1987, respectively. PVNGS operational findings are presented in references 6-8. The Radiation Measurements Facility (RMF) radiological assessments for 1988 and 1989 are found in references 9 and 10. This report contains the measurements and findings for 1990.

2.0 Descri tion of the Monitorin Pro ram The pre-operational radiological envirowentaL monitoring program, which began in 1979, was performed by PVHGS and outside organizations. These organizations continued the program into the operational phase of PVHGS. In 1988, the RMF assuned responsibility for sample collection, assay, data processing, and the REMP annual report. TLD measurements, collection of sludge, water influent samples, and the Land use census are conducted by PVNGS personnel.

2.1 The ASU Radiation Measurements Feei lit In the spring of 1983, the RMF implemented a Long-term independent radiological envirormentaL assessment program for the PVHGS.

In July 1987, the RMF was certified as a vendor by the APS Vendor Quality Program and assumed responsibility for many of the enviroanentaL assessments performed in support of the nuclear power station.

RMF staff are trained to perform routine sampling of air, surface and ground water, drinking water, milk, sludge, and vegetation. In accordance with the RMF Quality Assurance Program, all samples are collected using PVNGS procedures and analyzed using written and approved RMF procedures. Annual audits of the program are conducted by the APS Vendor Quality Organization.

To provide the highest quality results, the RMF participates in radiochemistry intercomparison programs with the United States Enviroreental Protection Agency (USEPA) and the Bureau of Radiation and Medical Devices (BRMD) of the Canadian Department of Health and lie l fare.

2.2 1990 PVNGS Radiolo ical Monitorin Pro ram The assessment program consists of routine measurements of background gamna radiation and of radionuclide concentrations in media such as air, groundwater, drinking water, surface

~ater, fresh milk, vegetation, and sludge.

Samples were collected by PVHGS or RMF personnel at the monitoring sites shown in Figures 2.1 and 2.2. The specific sample types, sampling locations, and sampling frequencies as set forth in Palo Verde Nuclear Generating Station Technical Specifications (11] are presented in Tables 2 ' and 2.2. Other samples not required by reference 11 were processed in accordance with contractual obligations or written requests from PVHGS.

0 Background gamna radiation measurements are performed using thermoluminescent dosimetry at fifty locations by PVNGS.
