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

e t

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

3.1.2 Honthly composited samples were collected at four residence wells. Honthly composited samples were collected in 500 mL glass bottles and in one gallon cubitainers. For the bi-weekly analyses, samples were collected in one-gallon cubitainer and were acidified with HCl 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 HCl in the laboratory prior to analysis.

3.2 ~te etetiee Vegetation samples were collected by RMF personnel using PVNGS procedures.

3.2.1 Vegetation samples were scheduled to be collected monthly, as available.

3.3 Air Filters and Canisters Air samples were collected by RMF personnel using PVNGS procedures.

3.3.1 Air particulate filters and charcoal canisters were exchanged at 12 sites on a ~eekly basis until October 1990 when Site ¹44 was deleted:

3.4 Hi lk Hilk samples were collected by RHF personnel, using PVNGS procedures.

3.4.1 Monthly milk samples were obtained from five dairies during the year.

Samples were collected in 1-gallon cubitainers to which 100 mL of carrier/preservative was added. No samples were available from the goats located at Site ¹64.

0 3.5 ~Stud e Sludge samples were collected by RMF personnel using PVHGS procedures.

3.5.1 Quarterly sludge samples were obtained frcm several on-site locations.

Samples were collected using 1000-mL plastic bottles.

4.0 Anal tical Procedures A surmary of RHF 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 LLO calculations are the same as used for actual measurements.

4.1 Garnna S ctrometr All gamna spectra are obtained from Ge(Li) or MPGe detectors. Efficiency calibrations are done annually, and in triplicate, for each geceetry used. The calculations are performed with a solution of mixed gamM ray cmitters whose activities are explicitly traceable to the U.S. National Institute of Standards and Technology.

4.1.1 Ilater Samples are counted in a one-liter Harinelli beaker. To reduce the counting time, up to two liters may be evaporated to one-liter and counted.

4.1.2 Milk Hi lk is counted as received, in a one-liter Harinelli 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. Honthly composites consist of 4-5 filters stacked in a plastic dish on the detector and counted.

4.1.5 Charcoal Canisters, Charcoal canisters are counted on a twin Hai(Tl) detector system. Gamma spectroscopy is used only for verification if 1-131 is detected by Mal(TI).

Counting efficiency is determined by, spiking blank canisters with 1-131 traceable

0 to the National Institute of Standards and Technology (HIST) ~ A canister spiked with Ba-133 is used to verify system performance prior to counting each week' samples.

4.1.6 ~SIud e Sludge was packed uniformly in a 500-mL Harinelli beaker and counted.

4.2 Gross Beta Activit 4.2.1 Water Samples are converted to nitrates and then evaporated to dryness in stainless steel planchettes, which are then flamed and counted.

4,2.2 Air Particulate Filters Efficiency calibration is obtained by depositing a known amount of HIST 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 mediun. Samples are counted as received after allowing 10 days for decay of radium and thoriun daughters.

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

4.4 Iodine-131 4.4.1 Water Radioiodine and added carrier are oxidized to 12 and extracted into chloroform, reduced and back-extracted into aqueous bisulfite, precipitated as Pdi2, and counted in a low-background gas-flow proportional counter. Counting efficiency is corrected fpr self-absorption by adding a known amount of HIST-traceable I-131 standard to a series of samples containing or varying amounts of iodide, precipitating as Pdi2, and counting in a low-background gas-flow proportional counter.

4' '

Radioiodine and added carrier are adsorbed onto Dowex 1-XG anion exchange resin, stripped with hypochlorite, oxidized to I2, extracted into chloroform and determination completed as for water samples.

0

12 4.5 Strontiun-89 and Strontiun-90 Radiostrontiun and added carrier are precipitated from the samples as carbonates. Calcium and other elements are separated by differential solubility in acetone and repeated extractions with Funing 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-89. 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.

17 5.0 Nuclear Instrunentation 5.1 Detectors and E ui nt Gamna spectra are analyzed by a Canberra Series 95 Hultichannel Analyzer (HCA) using a HicroVax computer. Four Detectors are available:

1) PGT Ge(Li), 26K efficiency, 1.90 keV FWHH 9 1332.5 keV')

Canberra Ge(Li), 14K efficiency, 2.08 keV FWHM 9 1332.5 keV

3) ORTEC HPGe, 13K efficiency, 1.98 keV FWHH 9 1332.5 keV

4) ORTEC HPGe, 43K efficiency, 1.80 keV FWHH 9 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 rti Criteria 6.1 Lower Limits of Detection The lower limits of detection (LLO) and the method for calculation are specified in the PVNGS Technical Specifications (11] and are presented in Table 6. l. RHF a priori LLDs are presented in Table 6.2.

6.2 Data Re rtin Criteria All results which are less than the Technical Specifications defined LLD, but greater than the a posteriori LLO are reported at the amount of activity determined and its respective error. Errors are presented as percent one sigma.

l8 Occasionally the PVNGS Technical Specifications a priori LLOYD, [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 circunstances.

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

24 8.0 Results and Oata inter retation Results and interpretation of the data for all of the samples analyzed during 1990 are presented in the following sections. Assessment of pre-operational and operational data revealed no significant changes to envirormental radiation levels. There was no observed impact on the environment due to PVNGS operations in 1990.

8.1 Air Particulates Meekly gross beta results in quarterly format, are presented in Tables 8.1 through 8.4.

Table 8a5 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 baseline and previous operational results.

Table 8.6 displays the results of gamna spec on the monthly composite. Ho Cs-134 or -137 was observed.

8.2 Airborne Radioiodine Tables 8.7 through 8.10 present the quarterly radioiodine results. Ho radioiodine was detected in any of the samples.

8.3 ~ss station Table 8.11 presents 1-131, Cs-134 and Cs-137 data for the vegetation samples. Ho activity was observed in any of the samples.

8.4 Orinkin Mater All samples were analyzed for 1-131 (radiochemical), Gross Beta, H-3, and for gamna-emitting nuclides. Results of these analysis are sumurized in Tables 8.12 and 8.13. Gross Beta activity ranged from less than three pCi/L to a high of eighteen pCi/L (Shepard Residence 1/30/90). Tritiun results were less than LLO for all drinking water samples. Ho gamna-emitting nuclides of man-made origin were detected. All 1-131 results were less than LLO ~

25 8.5 Groundwater All groundwater samples were analyzed for H-3, I-131, and for gannu-emitting nuclides.

Results obtained from the analysis of the samples are presented in Table 8.14.

Ho radioactivity was observed above the LLD values for I-131, H-3, or gaama-emitting nuclides.

8.6 Surface Water Surface water samples from the Reservoir and Evaporation ponds were analyzed for Gross Beta, Sr-89, Sr.90, H-3 and gamna-emitting nuclides. Results are presented in Tables 8.15 through 8.17. I.131 was observed in all surface waters. The highest concentrations were 28 pCI/L (12-4-90) in the Reservoir, 13 pCi/L in Evaporation Pond ¹1 (10-16, 23, 30-90) and 14 pCi/L Evaporation Pond ¹2 (12-18-90) ~

Influent samples collected by the Water Reclamation Facility (WRF) and were analyzed for ger+a-emitting nuclides and H-3. The results, presented in Table 8.19, demonstrate that I-131 was observed routinely. The highest concentration was 86 pCi/L (4-17-90). The results are consistent with essays from the previous years.

Gamna 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 observed in the cooling towers of operating units. The highest concentrations ware 184 pCi/L (12-4-90), 177 pCi/L (12-4-90) and 185 pCi/L (10-9-90) for Units ¹1, ¹2, and ¹3, respectively.

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 1-131 is a result of radiopharmaceutical discharges into the Phoenix sewage system. Refer to Section 11 of the 1988 AREOR for a detailed explanation.

Mater samples from the Retention Basins were analyzed for Tritium and for ganma-emitting nuclides. The results, presented in Tables 8.23 and 8.24, show that Cs-134, Cs-137, and I-131 concentrations were above LLO in a few of the samples collected during the year. Co-60 and Mn-54 were observed in the oil portion of the sample obtained from Retention Basin ¹2 on 11-13-90. TritiINI was detected in both Retention Basins routinely.

26 Table 8.25 presents gamma spectrometry and tritium measdrements of samples collected from Sedimentation Basin ¹2 (J-Hook Pond). No man-made ganma-emitting radionuclides or tritium were observed.

8.7 Milk Fresh Milk samples were analyzed by gamna spectrometry for Cs-134, Cs-137, Ba.140, and La-140. Samples were analyzed radiochemically for 1-131. 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 gamna spectrometry. Results can be found in Table 8.26. No man-made radionuclides were detected in either Sedimentation Basin ¹2 or STP Digester C. Beginning in June 1990, the STP Digester was collected weekly from the truck. Co-58 was detected once (7-13-90), Co-60 was detected three times (7-5, 13, 20-90) and I-131 was detected infrequently. The sludge from the Retention Basins contains Co-60, Cs-134, Cs.137 and Mn-54. Co-58 was also found twice in Retention Basin ¹2.

70 9.0 Thermoluninescent Dosimetr Results and Data Inter retation Thermoluminescent Dosimeters were placed in fifty locations ranging from one to forty-five miles from the Palo Verde Nuclear Generating Station. Beginning in 1984, the Panasonic Hodel 812 Dosimeter replaced all other TLD's in use. The 812 is a multi-element dosimeter combining two elements of Lithium Borate and two elements of Calcium Sulfate.

TLO locations are shown in Figures 2.1 and 2.2. TLD locations are described in Table 9.1. TLD results for 1990 are presented in Table 9.2. TLO results for 1984 through 1990 are presented in Figure 9.1 (excluding transit control TLD fI45) ~

TLD results for 1990 are consistent with preoperational data.

75 10.0 Land Use Census 10.1 Introduction In accordance with PVNGS Tcchnical SpcciTication 3.12.2, the annual Land Use Census was performed within a five mile radius of thc midline of Unit 2 containment between November and December, 1990.

Observations were made in each of the 16 meteorological sectors to determine the ncarcst milking animals, residences, and gardens of greater than 500 square feet.

This census was completed by driving the roads and speaking with residents within a five mile radius of PVNGS.

Thc results of the Land Use Census are prcsentcd in Table 10.1 and discussed below.

The directions and distances listed are in sectors and miles l'rom the Unit 2 containmcnt. The mileage was estimated from map positions of each location.

Unless othetwisc stated, the actual location is the same as stated in the 1989 AREOR.

10.2 Census Results 10.2.1 Nearest Resident There were two changes in thc nearest resident status noted in the 1990 census. These changes were in the SSE arid the WSW sectors.

10.2.2 Milking Animals The milk goats that were located in the ENE sector in thc 1989 census are no longer located in this location.

10.2,3 Vegetable Gardens Thcrc was one change in the garden locations. The garden located in thc N sector in thc 1989 census is no longer in usc.

10,3 Conclusion Avo changes were made to the REMP as a result of the 1990 Land Use Census. The milking animals (goats) located 5 miles ENE of PVNGS werc dclctcd from the REMP as there were no replacement milk animals located within the 5 miles. The garden located 2 miles N of PVNGS was deleted from the REMP as there was no replacement garden located within thc 5 miles.

77 11.0 ~ Sunna and Conclusions The conclusions are based on a review of the radioassay results and background gamna radiation measurements for the 1990 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 uraniun or thoriun series, C-14, or K-40.

A summary of all sample results for 1990 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), 1-131 concentrations in the Reservoir, Cooling Towers 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 enviroreental monitoring program annual reports. [1.10]
