.iABSTRACTThe Radiological Environmental Monitoring Program (REMP) is an ongoing program conducted byArizona Public Service Company (APS) for the Palo Verde Nuclear Generating Station (PVNGS).Various types of environmental samples are collected near PVNGS and analyzed for plant relatedradionuclide concentrations.
During 2014, the following categories of samples were collected by APS:* Broad leaf vegetation
- Ground water* Drinking water* Surface water* Airborne particulate and radioiodine
- Goat milk* Sludge and sedimentThermoluminescent dosimeters (TLDs) were used to measure environmental gamma radiation.
TheEnvironmental TLD program is also conducted by APS.The Arizona Radiation Regulatory Agency (ARRA) performs radiochemistry analyses on variousduplicate samples provided to them by APS. Samples analyzed by ARRA include onsite samples fromthe Reservoirs, Evaporation Ponds, and two (2) deep wells. Offsite samples analyzed by ARRAinclude two (2) local resident wells. ARRA also performs air sampling at seven (7) offsite locations identical to APS and maintains approximately fifty (50) environmental TLD monitoring locations, eighteen (18) of which are duplicates of APS locations.
A comparison of pre-operational and operational data indicates no changes to environmental radiation levels.(NOTE: Reference to APS throughout this report refers to PVNGS personnel)
PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -20141 OPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM1. Introduction This report presents the results of the operational radiological environmental monitoring programconducted by Arizona Public Service Company (APS). The Radiological Environmental Monitoring Program (REMP) was established for the Palo Verde Nuclear Generating Station(PVNGS) by APS in 1979.This report contains the measurements and findings for 2014. All references are specifically identified in Section 12.The Radiological Environmental Monitoring Program provides representative measurements ofradiation and of radioactive materials in those exposure pathways and for those radionuclides thatlead to the highest potential radiation exposures of members of the public resulting from thestation operation.
This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFRPart 50 and thereby supplements the radiological effluent monitoring program by verifying thatthe measurable concentrations of radioactive materials and levels of radiation are not higher thanexpected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.
Guidance for this monitoring program is provided by the US NuclearRegulatory Commission (USNRC) in their Radiological Assessment Branch Technical Positionon Environmental Monitoring, Revision 1, November 1979 (incorporated into NUREG 1301).Results from the REMP help to evaluate sources of elevated levels of radioactivity in theenvironment (e.g., atmospheric nuclear detonations or abnormal plant releases).
The Land Use Census ensures that changes in the use of areas at and beyond the site boundary areidentified and that modifications to the REMP are made if required by the results of this census.This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50.The Interlaboratory Comparison Program is provided to ensure that independent checks on theprecision and accuracy of the measurements of radioactive material in environmental samplematrices are performed as part of the quality assurance program for environmental monitoring inorder to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to10 CFR Part 50.Results of the PVNGS pre-operational environmental monitoring program are presented inReference 1.The initial criticality of Unit 1 occurred May 25, 1985. Initial criticality for Units 2 and 3 wereApril 18, 1986, and October 25, 1987, respectively.
PVNGS operational findings (historical) arepresented in Reference 2.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -20142 I.j2. Description of the Monitoring ProgramAPS and vendor organizations performed the pre-operational radiological environmental monitoring program between 1979 and 1985. APS and vendors continued the program into theoperational phase.2.1. Radiological Environmental Monitoring ProgramThe assessment program consists of routine measurements of environmental gammaradiation and of radionuclide concentrations in media such as air, groundwater, drinkingwater, surface water, vegetation, milk, sludge, and sediment.
Samples were collected by APS at the monitoring sites shown in Figures 2.1 and 2.2. Thespecific sample types, sampling locations, and sampling frequencies, as set forth in thePVNGS Offsite Dose Calculation Manual (ODCM), Reference 4, are presented in Tables2.1, 2.2 and 9.1. Additional onsite sampling (outside the scope of the ODCM) is performed to supplement the REMP. All results are included in this report. Routine sample analyseswere performed at the onsite Central Chemistry Laboratory and Operating Unitlaboratories.
Analyses for hard-to-detect radionuclides were performed by GELLaboratories LLC.Environmental gamma radiation measurements were performed by APS using TLDs atfifty (50) locations near PVNGS. The PVNGS Dosimetry Department is accredited by theNational Voluntary Laboratory Accreditation Program (NVLAP) to perform ionizingradiation dosimeter analyses.
In addition to monitoring environmental media, a land use census is performed annually toidentify the nearest milk animals, residents, and gardens.
This information is used toevaluate the potential dose to members of the public for those exposure pathways that areindicated.
2.2. Radiological Environmental Monitoring Program Changes for 2014There were no changes to the Radiological Environmental Monitoring Program thatimpacted the Off-site Dose Calculation Manual (ODCM) Revision 26.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -20143
- 2.3. REMP Deviations/Abnormal Events SummaryDuring calendar year 2014, there were three (2) deviations/abnormal events with regardto the monitoring program.
Refer to Table 2.3 for more detail and any corrective actionstaken.The first two (1-2) deviations were exceedances of the quarterly 1-131 reporting level of20 pCi/L. This occurred at the following locations:
45 acre reservoir first calendarquarters, Evaporation Pond 1 A first calendar
- quarters, Evaporation Pond 2A thirdquarter.
The source is radiopharmaceutical 1-131 that originates in the Phoenix sewageeffluent that supplies makeup to the Reservoirs and Circulating Water system. Thiswater is wasted to the Evaporation Ponds. This is not a plant effluent.
The third (3) and final deviation for 2014 was an air sample pump failure at site #17.This resulted in an undetermined sample volume sample for that week's sample. Defaultflow values were assumed for analysis of this sample. This is a supplemental site, notrequired per the ODCM.2.4. Ground Water Protection PVNGS has implemented a groundwater protection initiative developed by the NuclearEnergy Institute (NEI). The implementation of this initiative, NEI 07-07 (Industry GroundWater Protection Initiative
-Final Guidance
- Document, August 2007), provides addedassurance that groundwater will not be adversely affected by PVNGS operations.
Several monitoring wells have been installed to monitor the subsurface water and shallowaquifer at Units 1, 2, and 3. These wells are sampled monthly and quarterly for chemicaland radiological parameters.
The State of Arizona Aquifer Protection Permit (Area-Wide)
No. P-100388 (APP) provides agreed upon monitoring parameters and reporting thresholds.
Sample results for the shallow aquifer wells are reported in the PVNGSAnnual Radioactive Effluent Release Report (ARERR).
The State of Arizona APPprovides specific regulatory criteria for groundwater protection.
Three subsurface samples were obtained, one each from Units 2 and 3 tritium monitoring wells, and one from the shallow aquifer outside of the Unit 1 radiological controlled area(RCA). These samples were analyzed for hard-to-detect radionuclides (e.g. C-14, Fe-55,Ni-63, Sr-90) as a verification that there are no underground leaks from plant systems thatmay affect groundwater.
All results were <MDA. Refer to Table 8.12 for sample results.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -20144 S ITable 2.1 SAMPLE COLLECTION LOCATIONS SAMPLESIT.. SAMPLE TYPE LOG f LOCATIONDESCRIPTION

The 45 acre Reservoir andEvaporation Pond IA exceededthe first quarter 1-131 reporting level of 20 pCi/liter.
- 2. Evaporation Pond IA exceededthe first quarter 1-131 reporting level of 20 pCi/liter resulting in aunity value greater than 1.0 (one).The quarterly tritium sample had avalue of 2,640 pCi/liter.
Actions taken1. Initial sample results exceeding 20 pCi/liter are validated when seen in surface water. The verification analysisresults also showed levels > 20 pCi/liter for theEvaporation Pond 1A sample. However, the 45 acreReservoir validating count was less than 20 pCi/liter.
The elevated 1-131 concentration is due toradiopharmaceutical 1-131 that is present in thereclaimed sewage water that supplies Circulating Waterand is not the result of plant effluents.
The source isradiopharmaceutical 1-131 that originates in the Phoenixsewage effluent that supplies makeup to the Reservoirs and Circulating Water system. This water is wasted tothe Evaporation Ponds via Circulating Water blowdown.
Because the 1-131 is not the result of plant effluents, noSpecial Report is required.
This information is providedin this report as required by the ODCM. Refer toCorrective Action Program documents CRDR 4499971,CRDR 4604440, and 4568037 for the evaluation ofexceeding the ODCM Reporting Level. No additional actions are necessary.
- 2. Evaporation Pond IA had an 1-131 validated resultgreater than the ODCM Reporting Level. Low leveltritium (2,640 +/- 244 pCi/liter) was detected inEvaporation Pond IA. This tritium value is below theODCM Reporting Level. If more than one radionuclide from the ODCM Reporting Level table is detected, aunity value calculation must be performed.
The elevated1-131 concentration, originating from Phoenixradiopharmaceuticals, accounted for 96% of the unityvalue. Corrective Action Program document 4604440documents this occurrence and subsequent evaluation.
No further actions required.

- 6. Isotopic Detection Limits and Reporting Criteria6.1. Lower Limits of Detection The lower limits of detection (LLD) and the method for calculation are specified in the PVNGSODCM, Reference
- 4. The ODCM required a priori LLDs are presented in Table 6.1. For reference, a priori LLDs are indicated at the top of data tables for samples having required LLD values.6.2. Data Reporting CriteriaAll results that are greater than the Minimum Detectable Activity (MDA) (a posteriori LLD) arereported as positive activity with its associated 2; counting error. All results that are less than theMDA are reported as less than values at the associated MDA. For example, if the MDA is 12pCi/liter, the value is reported as <12.Typical MDA values are presented in Table 6.3.Occasionally, the PVNGS ODCM apriori LLDs may not be achieved as a result of:* Background fluctuations
- Unavoidably small sample sizes* The presence of interfering radionuclides
- Self absorption corrections
- Decay corrections for short half-life radionuclides
- Other uncontrollable circumstances In these instances, the contributing factors will be noted in the table where the data are presented.
A summary of deviations/abnormal events is presented in Table 2.3 and includes a description ofany sample results that did not meet apriori LLD requirements.
PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -201415 6.3. LLD and Reporting Criteria OverviewMaking a reasonable estimate of the limits of detection for a counting procedure or a radiochemical method is usually complicated by the presence of significant background.
It must be considered thatthe background or blank is not a fixed value but that a series of replicates would be normallydistributed.
The desired net activity is the difference between the gross and background activitydistributions.
The interpretation of this difference becomes a problem if the two distributions intersect as indicated in the diagram.BACKGROUND GROSSIf a sufficient number of replicate analyses are run, it is expected that the results would fall in anormal Gaussian distribution.
Standard statistics allow an estimate of the probability of anyparticular deviation from the mean value. It is common practice to report the mean +/- one or twostandard deviations as the result. In routine analysis, such replication is not carried out, and it is notpossible to report a Gaussian standard deviation.
With counting procedures,
- however, it is possibleto estimate a Poisson standard deviation directly from the count. Data are commonly reported as themeasured value +/- one or two Poisson standard deviations.
The reported values are then considered to give some indication of the range in which the true value might be expected to occur.A LLD is the smallest amount of sample activity that will yield a net count for which there isconfidence at a predetermined level that activity is present.
LLDs are calculated values forindividual radionuclides based on a number of different factors including sample size, countingefficiency and background count rate of the instrument, the background and sample counting time,the decay time, and the chemical recovery of the analytical procedures.
A minimum detectable activity value (MDA) is the smallest amount of activity that can be detected in an actual sample anduses the values obtained from the instrument and outcome of the analytical process.
Therefore, theMDA values may differ from the calculated LLD values if the sample size and chemical
- recovery, decay values, or the instrument efficiency, background, or count time differed from those used in theLLD calculation.
PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -201416 The factors governing the calculation of the LLD and MDA values are discussed below:1. Sample Size2. Counting Efficiency The fundamental quantity in the measurement of a radioactive substance is the number ofdisintegrations per unit time. As with most physical measurements in analytical chemistry, anabsolute measurement of the disintegration rate is seldom possible, rather it is necessary to comparethe sample with one or more standards.
The standards determine the counter efficiency that maythen be used to convert sample counts per minute (cpm) to disintegrations per minute (dpm).3. Background Count RateAny 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 surrounding materials,
- 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. Thebackground counting rate will depend on the amounts of these types of radiation and the sensitivity of the counter to the radiation.
- 4. Background and Sample Counting TimeThe amount of time devoted to the counting of the background depends on the level of activitybeing measured.
In general, with low level samples, this time should be about equal to that devotedto counting a sample.5. Time Interval between Sample Collection and CountingDecay measurements are useful in identifying certain short-lived nuclides.
The disintegration constant is one of the basic characteristics of a specific radionuclide and is readily determined, if thehalf-life is sufficiently short. To ensure the required LLDs are achieved, appropriate decaycorrection values are used to account for radioactive decay during transit time and sampleprocessing.

- 8. Data Interpretations and Conclusions Associated with the analytical process are potential random and systematic errors. Systematic errors can becaused by instrument malfunctions, incomplete precipitation, back scattering, and self-absorption.
Randomerrors are beyond the control of the analyst.Efforts are made to minimize both systematic and random errors in the data reported.
Systematic errors areminimized by performing reviews throughout the analysis.
For example, instruments are checked routinely with radioactive
- sources, and recovery and self-absorption factors based on individual sample analyses areincorporated into the calculation equations where necessary.
Random errors are reduced by comparing alldata to historical data for the same site and performing comparisons between analytical results whenavailable.
In addition, when data do not appear to match historical
- results, analyses may be rerun on aseparate aliquot of the sample to verify the presence of the activity.
The acceptance of data is dependent upon the results of quality control samples and is part of the data review process for all analytical results.The "plus or minus value" reported with each analytical result represents the counting error associated with the result and gives the 95% confidence (2a) interval around the data.Most samples contain radioactivity associated with natural background/cosmic radioactivity (e.g. K-40,Th-234, and Be-7). Gross beta results for drinking water and air are due to natural background.
Gammaemitting radionuclides, which can be attributed to natural background
- sources, are not indicated in thismeomrt.Results and interpretation of the data for all of the samples analyzed during 2014 are presented in thefollowing sections.
8.1. Air Particulates Weekly gross beta results, in quarterly format, are presented in Tables 8.1 and 8.2. Gross betaactivity at indicator locations ranged from 0.010 to 0.071 pCi/m3.Mean quarterly activity isnormally calculated using weekly activity over a thirteen (13) week period. Also presented in thetables are the weekly mean values of all the sites as well as the percent relative standard deviation (RSD %) for the data.Tables 8.3 displays the results of gamma spectroscopy on the quarterly composites of the weeklysamples.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -201425 8.2. Airborne Radioiodine Tables 8.4 and 8.5 present the quarterly radioiodine results.
Radioiodine was not observed in anysamples.8.3. Vegetation Table 8.6 presents gamma isotopic data for the vegetation samples.
No gamma emittingradionuclides were observed in any of the samples..
8.4. MilkTable 8.7 presents gamma isotopic data for the goat milk samples.
No gamma emittingradionuclides were observed in any of the samples.8.5. Drinking WaterSamples were analyzed for gross beta, tritium, and gamma emitting radionuclides.
Results of theseanalyses are presented in Table 8.8. No tritium or gamma emitting radionuclides were detected inany samples.
Gross beta activity ranged from less than detectable to a high of 6.6 pCi/liter.
Thegross beta activity is attributable to natural (background) radioactive materials.
8.6. Ground WaterGround water samples were analyzed from two onsite wells (regional aquifer) for tritium andgamma emitting radionuclides.
Results obtained from the analysis of the samples are presented inTable 8.9.No tritium or gamma emitting radionuclides were observed in any of the samples.8.7. Surface WaterSurface water samples from the Reservoirs and Evaporation Ponds were analyzed for tritium andgamma emitting radionuclides.
The two Reservoirs contain processed sewage water from the Cityof Phoenix and are approximately 45 and 85 acres in size. The three Evaporation Ponds receivemostly circulating water from main turbine condenser cooling and are about 200-250 acres each.Sample results are presented in Table 8.10. 1-131 was observed in both reservoirs andEvaporation Ponds IA, 1B, and 2A. The 1-131 levels ranged from 14 pCi/L -42 pCi/L. 1-131 inthese surface water locations is a result of radiopharmaceutical 1-131 in the Phoenix sewageeffluent and is not attributable to plant effluents.
Tritium was routinely observed in the Evaporation Ponds. The highest concentration was 2640pCi/liter.
Tritium was not detected in the Reservoirs.
The tritium identified in the Evaporation Ponds has been attributed to permitted plant gaseous effluent releases and secondary plant liquiddischarges (e.g. condensate overboard discharge, secondary side steam generator drains, secondary plant sumps, demineralizer regeneration waste). The tritium concentrations were compared tohistorical values and are considered typical for the Evaporation Ponds.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -201426 WRF Influent (Phoenix sewage effluent containing radiopharmaceutical 1-131) samples collected by the WRF were analyzed for gamma emitting radionuclides and tritium.
The results, presented in Table 8.10, demonstrate that 1-131 was observed routinely.
The 1-131 concentration rangedfrom less than detectable to 59 pCi/liter.
None of the samples analyzed indicated the presence oftritium.Table 8. 10 also presents gamma spectroscopy and tritium measurements of samples collected fromSedimentation Basin 2. This basin collects rain water from site runoff and was dry for most of theyear. Low concentrations of tritium were identified in two (2) of eleven (11) samples ranging fromless than detectable to 534 pCi/liter.
The tritium was attributed to rain washout of plant gaseouseffluent releases.
No gamma emitting radionuclides were observed in the samples.8.8. Sludge and Sediment8.8.1. WRF Centrifuge waste sludgeSludge samples were obtained from the WRF centrifuge and analyzed by gamma spectroscopy.
I-131 activity in the sludge is consistent with historical values and, as previously discussed, is due toradiopharmaceuticals in the WRF Influent.
The concentration of 1-131 ranged from 202 to 843pCi/kg.In- 111 was also identified in the sludge in one sample at 139 pCi/kg. It was previously established that In-I ll is also used in the Phoenix area as a radiopharmaceutical.
Results for WRF centrifuge waste sludge can be found in Table 8.11.8.8.2. Cooling Tower sludgeSludge/sediment originating from the Unit 1 and Unit 2 Cooling Towers and Circulating Watercanals was disposed of in the WRF sludge landfill during 2014. Sample results can be found inTable 8.11.8.9. Data TrendsFigures 8.1-8.8 present data in graphical format. Historical data are displayed for comparison wherepractical.
8.10. Hard-to-Detect Radionuclide ResultsTable 8.12 shows the results of the three subsurface samples obtained from 3 tritium monitoring points. These samples were analyzed for hard-to-detect radionuclides (e.g. C-14, Fe-55, Ni-63, Sr-90) and all results were <MDA. These results indicate that no leaks from plant systems haveaffected groundwater.

- 9. Thermoluminescent Dosimeter (TLD) Results and DataThe environmental TLD used at PVNGS is the Panasonic Model 812 Dosimeter.
The Model 812is a multi-element dosimeter combining two elements of lithium borate and two elements ofcalcium sulfate under various filters.TLDs were placed in fifty locations from one to thirty-five miles from the PVNGS. TLD locations are shown in Figures 2.1 and 2.2 and are described in Table 9.1. TLD results for 2014 arepresented in Table 9.2. Historical environmental gamma radiation results for 1985 through 2014are presented in graphical form on Figure 9.1 (excluding transit control TLD #45).Figure 9.2 depicts the environmental TLD results from 2014 as compared to the pre-operational TLD results (excluding sites #41 and #43, as they were deleted and later assigned to a newlocation, and #46-50, as they had no pre-op TLD at the location for comparison).
The site to sitecomparisons indicate a direct correlation with respect to pre-operational results.
It is evident thatthe offsite dose, as measured by TLDs, has not changed since Palo Verde became operational.

- 10. Land Use Census10.1. Introduction In accordance with the PVNGS ODCM, Section 6.2, the annual Land Use Census wasperformed in April 2014.Observations were made in each of the 16 meteorological sectors to determine thenearest milking animals, residences, and gardens of greater than 500 square feet. Thiscensus was completed by driving the roads and speaking with residents.
The results of the Land Use Census are presented in Table 10.1 and discussed below.The directions and distances listed are in sectors and miles from the Unit 2 containment.
10.2. Census ResultsNearest ResidentThere was no change in nearest resident status from the previous year. Dosecalculations indicated the highest dose to be 0.178 mRem.Milk AnimalThere was no change in milk animal status from the previous year. Dose calculations indicated the highest dose to be 0.508 mRem.Vegetable GardensThere was no change in nearest garden status. Dose calculations indicated the highestdose to be 0.490 mRem.See Table 10.1 for a summary of the specific results and Table 2.1 for current samplelocations.
Figures 10.1 through 10.3 provide graphs depicting historical calculated doses fornearest residents, nearest milk receptor, and nearest garden receptor locations in eachsector.Differences in calculated doses are the result of many variables, including;
- Changes in receptor locations from year to year (proximity to the power plant)" Changes in local meteorology (wind direction, wind speed, precipitation, temperature)

Several new milk animals were identified in 2009 that were closer to the power plant than in thepast, resulting in generally higher calculated doses in that calendar year.No milk samples have indicated any plant related radionuclides.
Additionally, milk animals in the desert environment are normally fedstored feed and are not on pasture.
The calculated doses are conservative since they include pastured feed as part of the calculation.

- 11. Summary and Conclusions The conclusions are based on a review of the radio assay results and environmental gammaradiation measurements for the 2014 calendar year. Where possible, the data were compared topre-operational sample data.All sample results for 2014 are presented in Tables 8.1-8.12 and do not include observations ofnaturally occurring radionuclides, with the exception of gross beta in air and gross beta indrinking water. Table 11.1 summarizes the ODCM required samples and is in the formatrequired by the NRC BTP on Environmental Monitoring.
1-131 identified in the Evaporation Ponds, WRF Influent, WRF Centrifuge sludge, andReservoirs is the result of offsite sources and appears in the effluent sewage from Phoenix.
Thelevels of 1-131 detected in these locations are consistent with levels identified in previous years.Tritium concentrations identified in surface water onsite have been attributed to PVNGSpermitted gaseous effluent releases and secondary plant releases.
These concentrations areconsistent with historical values.Environmental radiation levels are consistent with measurements reported in previous Pre-operational and Operational Radiological Environmental annual reports, References 1and 2.There was no measurable radiological impact on the environment in 2014 resulting from theoperation of PVNGS.PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT -201467 TABLE 11.1 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAM ANNUAL SUMMARYPalo Verde Nuclear Generating Station Docket Nos.
