The VENTILATION EXHAUST TREATMENT SYSTEM shall be used to reduce radioactive materials in gaseous waste prior to their discharge when the projected doses due to gaseous effluent releases, from each reactor unit, to areas at and beyond the SITE BOUNDARY when averaged over 31 days, would exceed 0.3 mrem to any organ of a MEMBER OF THE PUBLIC.9 PVNGS ARERR 2006 1.3 Total Dose 1.3.1 PVNGS ODCM Requirement 5.1 The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to direct radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.2.0 MAXIMUM PERMISSIBLE CONCENTRATIONS Air: Release Concentrations are limited to dose rate limits described in section 1.2.1 of this report.3.0 AVERAGE ENERGY The average energy (E) of the radionuclide mixture in releases of fission and activation gases is not applicable to PVNGS.4.0 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY IN GASEOUS EFFLUENTS For continuous releases, sampling is in accordance with PVNGS ODCM Table 3-1.Particulate and iodine radionuclides are sampled continuously at the Plant Vent and Fuel Building exhaust points. The particulate filters and charcoal cartridges are exchanged for analysis at least four times per month. Noble gas and tritium are sampled at least once per 31 days. The hourly average Radiation Monitoring System (RMS) effluent monitor readings are used, when available, to account for increases and decreases in noble gas concentrations between noble gas grab samples. The tritium concentration is assumed constant between sampling periods.For batch releases, sampling is also in accordance with PVNGS ODCM Table 3-1. For containment purges, the noble gas concentration may be adjusted to account for decreases or increases In concentration during the purge using RMS readings.

The volume of air released during the purge is determined using the exhaust fan rated flow rate. For Waste Gas Decay Tank releases, the volume released is corrected to standard pressure.Effective January 1, 2004, Containment Purge release permits are updated by removing the permit pre-release particulate and iodine activity.

This eliminates double accounting for the Containment Purge particulate and iodine activity at the Plant Vent but allows the particulate and iodine activity to be included in the Containment Purge pre-release dose projection.

The Lower Limit of Detection (LLD) of a measurement system is defined in Table 3 -1 of the PVNGS ODCM. An average LLD for each radionuclide is provided In Table 3.10 PVNGS ARERR 2006 5.0 BATCH RELEASES 5.1 Gaseous.Batch release durations are presented in Table 2.5.2 Liquid None.6.0 ABNORMAL RELEASES None.7.0 OFFSITE DOSE CALCULATION MANUAL AND PROCESS CONTROL PROGRAM (PCP) REVISIONS 7.1 ODCM, Revision 21, effective September 15, 2006, contains changes associated with the Implementation of the Radioactive Environmental Monitoring Program (REMP). The ODCM revision is Included as Appendix D.7.2 Revision to the Process Control Program (PCP) is included as Appendix E.8.0 EFFLUENTS AND SOLID WASTES 8.1 Gaseous Effluents Gaseous effluent information is presented in Table I through Table 41. Included in these tables are summaries of the effluents and estimated total error.8.2 Liquid Effluents There were no liquid effluent releases beyond the Site Boundary from PVNGS.8.3 Solid Waste Solid waste shipments are summarized in Table 42.11 PVNGS ARERR 2006 9.0 MISCELLANEOUS INFORMATION 9.1 EVAPORATION PONDS Releases made to the Evaporation Ponds are limited to the concentrations specified in PVNGS ODCM Requirement 3.2. The Evaporation Ponds were monitored in accordance with PVNGS ODCM Requirement 6.1.The average historical evaporation is approximately 12 Inches, per pond, for each of the first and fourth quarters, and 33 inches, per pond, for each of the second and third quarters.

This equates to 3.09E+1 1 cc evaporated from Pond One for each of the first and fourth quarters and 8.50E+11 cc evaporated from Pond One for each of the second and third quarters.

The amount evaporated from Pond Two is 2.89E+1 I cc for each of the first and fourth quarters and 7.96E+1 1 cc for each of the second and third quarters.

Using a site boundary X/Q of 5.OE-05 sec/m 3 for the evaporation ponds and equation 4-3 from the ODCM, the dose from the evaporation ponds to a hypothetical individual at the site boundary, for all pathways, is summarized in Table 1.9.2 RADIATION MONITORING SYSTEM SETPOINT VERIFICATION Current effluent monitor noble gas channel alert alarm setpoints are based on an assumed one per cent failed fuel source term. The current setpoints are more conservative than setpoints calculated using the actual noble gas source term presented in Table 38.9.3 RCS RADIOIODINE (TRM T5.0.600)There were no cases where primary coolant specific activity exceeded the Technical Specification 3.4.17 limits during the reporting period.9.4 INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)There are no radioactive effluents from the NAC-UMS System. Direct dose at the Site Boundary is reported in the Annual Radiological Environmental Operating Report.9.5 MAJOR CHANGES TO THE RADIOACTIVE WASTE SYSTEMS (liquid, gaseous, and solid).Licensee-initiated major changes to the radioactive waste systems (liquid, gaseous, and solid) are submitted as part of the FSAR update (TRM T5.0.500.4.a).

12 PVNGS ARERR 2006 9.6 SIGNIFICANT INVESTIGATION REGARDING GROUNDWATER PROTECTION (CRDR 2869959)This information is being provided due to the identification of measurable licensed radioactive material in the onsite environs (within the Radiological Controlled Area) and heightened sensitivity to communicate the potential to affect groundwater.

On February 15, 2006 Palo Verde personnel observed water leakage into the Unit 2, Essential Pipe Density Tunnel through the 'B' Spray Pond (SP) supply line penetration seal (documented on Significant CRDR 2869959).

The seal and wall below the seal were observed to be wet, with a water puddle on the pipe chase floor. Unit 2 placed the 'B' Spray Pond pump into service for a scheduled pump run on February 16, 2006. Personnel observed that water accumulation at the penetration increased while the pump was operating.

In response to the observed in-leakage, station management decided to excavate the Unit 2 SP 'B'supply and return lines immediately west of the Essential Pipe Density Tunnel to inspect for leakage. Maintenance excavated lines 2PSPBLO30 and 2PSPBLO25 to look for leaks, but none were found. Additionally, the penetration seal around SPBL030 was removed to look for leaks, none were found, and the area was restored.A subsequent inspection in the Unit 3 Essential Pipe Density Tunnel identified similar leakage at the penetration for the SP 'A' return line (3PSPAL079) and SP'B' return line (3PSPBLO25) penetration seals. The seals for the return line penetrations were observed to be dripping while the SPA/B pumps were In operation.

The wall below the SP 'A' supply line (3PSPAL068) and SP 'B' supply line (3PSPBLO30) penetration seals showed dampness, but no visible water drops. Maintenance excavated the return line and the supply line to the 4'-4" top of pipe level. The excavation revealed no visible leaks and Maintenance restored the area.Process piping In Unit 3 associated with the Charging system (CH), Liquid Radwaste system (LR) and Fire Protection system (FP) were partially excavated in the area of the pipe chase penetrations.

The elimination of SP system piping leaks left these pipes suspect. No leaks were Identified by excavation.

In addition to the major excavation detailed above, a test hole, approximately 13 feet deep, was dug in the radiological controlled area yard to determine the extent of condition.

Water was subsequently discovered in the test hole and a sample was obtained in order to characterize the water and identify its source.Initial results from the unit laboratory (March 1, 2006 sample) indicated the presence of tritium. A confirmatory sample was collected and analyzed by the State certified laboratory at Palo Verde that confirmed the presence of tritium at a concentration of approximately 7.14E-05 uCi/mI. The Aquifer Protection Permit, Aquifer Quality Limit for tritium is 2.OOE-05 uCi/ml. The Palo Verde Environmental Control department notified the Arizona Department of Environmental Quality (ADEQ) of the possibility of a discharge of non-hazardous material that has the potential to cause groundwater limits to be exceeded.

The station also notified the Nuclear Regulatory Commission pursuant to 10CFR50.72 (b) (2) (xi);13 PVNGS ARERR 2006 specifically of a situation related to the protection of the environment, for which a notification to another government agency has been or will be made. Public meetings with local residents were held to inform the public and answer concerns.The direct root cause of the elevated levels of tritium In subsurface water samples from Unit 3 cannot be Identified.

The sources of the tritium come from washout and localized small volume spills. There is no evidence at this time that supports the presence of a system leak.The washout described in the preceding paragraph is historical.

It is due to past operations of the Boric Acid Concentrator (BAC) during rain and wash down of roofs or washout from rain during times when tritium condensation from the ventilation system was present.Atmospheric modeling, conducted as part of the investigation, does not support that rain washout of tritium is the source of the subsurface tritiated water accumulation at identified concentrations, with current operating conditions (not allowing BAC operations during periods of rain).Contributing causes of the condition in Unit 3 are the composition of the backfill and above ground grading and paving of the Unit 3 RCA yard.There is no indication that tritiated water has reached any aquifer. No Technical Specification effluent limits have been exceeded nor have any Offsite Dose Calculation Manual (ODCM) effluent limits been exceeded.

Federal effluent limits have not been exceeded.

Palo Verde has not identified any increased health or safety risk to the public or onsite personnel due to this condition.

The condition report is classified as significant by management direction due to recent industry events and public trust issues.Corrective actions are ongoing and include the Installation of several monitoring wells in the RCA at all three Units. These monitoring wells will be routinely sampled for radiological analyses and results will be reported in the PVNGS Annual Radioactive Effluent Release Report (ARERR). This reporting protocol was agreed upon by Industry leaders via the NEI Industry Ground Water Protection Voluntary Communication Protocol Interim Guidance Document (June 2006) for non-REMP well samples (with additional direction via a position paper developed during the industry RETS-REMP workshop).

14 PVNGS ARERR 2006 9.7 SAMPLES RESULTS FROM GROUNDWATER WELLS THAT ARE NOT DESCRIBED IN THE ODCM AS PART OF THE REMP (NEI Tritium Groundwater Initiative):

During 2006, sixteen on-site monitoring wells associated with the Site Aquifer Protection Permit (APP), as part of the groundwater monitoring program, were sampled. A summary of the wells associated with the APP groundwater monitoring program are as follows: Wells in the vicinity of the evaporation ponds Include 13 shallow aquifer and two intermediate aquifer monitoring wells. Of the 13 shallow aquifer wells, nine were monitored during 2006 as part of the APP monitoring program.Those included wells PV-14H, PV-14HB, PV-193A, PV-195A, PV-198AR, PV-33H, PV-33HB, PV-34H, and PV-Q8. Because wells PV-193A, PV-195A, PV-1 98AR, and PV-34H were still In IAL sampling, In accordance with the APP, the four wells PV-193B, PV-195B, PV-198B, and PV-34HB were not sampled during 2006. The two intermediate aquifer monitoring wells (APP-4 and APP-5) located south of the evaporation ponds were also monitored during 2006.Two shallow aquifer monitoring wells (PV-206A and PV-206B) in the vicinity of the retention basins were sampled during 2006 as part of the APP monitoring program. One intermediate aquifer monitoring well APP-8, which also is located near the retention basins, was under ambient monitoring during 2006, but was not yet part of the APP monitoring program.In the vicinity of the 80-acre water storage reservoir, there are the following wells: One shallow aquifer monitoring well, one intermediate aquifer monitoring well, and eighteen shallow or perched aquifer piezometers.

The shallow aquifer monitor well (PV-R2AR) was monitored during 2006 as part of the APP monitoring program. One Intermediate aquifer monitoring well, APP-7, was under ambient monitoring during 2006, but was not yet part of the APP monitoring program. The eighteen piezometers located around the reservoir were monitored during 2006 but were not part of the APP monitoring program.Two deep or regional monitoring wells (APP-3 and APP-6) located down-gradient from the evaporation ponds were monitored in 2006 as part of the APP monitoring program.Three shallow aquifer monitoring wells (APP-9, APP-1 0, and APP-11) were installed during 2006 as part of the tritium Investigation In the Units. Those wells are currently under ambient sampling and are not yet part of the APP monitoring program.The 16 monitoring wells associated with the APP were sampled once per quarter during 2006. Those samples were submitted to an ADHS-approved off-site laboratory for the analysis of organic and inorganic compounds.

In addition, those samples were submitted to Palo Verde's Central Laboratory for analysis of tritium and gamma isotopes.

The specific gamma isotope 15 PVNGS ARERR 2006 analyses requested varied according to the level of monitoring in accordance with the APP. Generally, tritium, cobalt, and cesium-1 37 were requested.

Other gamma isotopes that were requested for selected wells included iodine-131 and cesium-134.

During 2006, additional rounds of samples (typically, 4 rounds) were collected from the 16 APP wells for tritium analysis to evaluate the possible impact to groundwater from the tritium detected in the RCA yards of the Units.A total of 118 samples were analyzed for tritium during 2006. Of those samples, 55 samples were collected specifically for the evaluation associated with the tritium Investigation.

SIxty-three (63) samples were analyzed for cesium-1 37 and cobalt-60.

Eighteen (18) samples were analyzed for cesium-134.

Twenty-four (24) samples were analyzed for Iodine-131.

None of the samples collected from the APP wells during 2006 contained detectable levels of tritium or gamma isotopes.9.8 REPORT ADDENDUM None.16 PVNGS ARERR 2006 10.0 DISCUSSION 10.1 Unit One Unit One operated without a refueling outage.Maintenance outages: UIMI3A, 1-17-06 to 1-21-06 UlM13B, 3-18-06 to 7-7-06 UlM13C, 9-19-06 to 10-16-06 U1M13D, 10-21-06 to 10-23-06 Estimated number of fuel defects (source: INPO, CDE)Jan Feb Mar Apr May Jun Jul Aug 0 0 0 0 0 0 0 0 Sep Oct Nov 0 0 0 Dec 0 10.2 Unit Two Unit Two operated with a refueling outage (U2R13) from September 30, 2006 to November 14, 2006.Maintenance outages: U2M13C, 4-10-06 to 4-14-06 U2M13D, 7-26-06 to 7-28-06 10.3 Estimated number of fuel defects (source: INPO, CDE)Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 0 0 0 0 0 0 0 0 0 0 0 0 Unit Three Unit Three operated with a refueling outage (U3R12) from April 1, 2006 to May 12, 2006.Maintenance outages: U3M12E, 3-5-06 to 3-7-06 U3M13A, 7-1-06 to 7-3-06 U3M13B, 10-19-06 to 10-21-06 Estimated number of fuel defects (source: INPO, CDE)Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 0 0 0 0 0 0 0 0 0 0 0 0 17 PVNGS ARERR 2006 10.4 General PVNGS does not have a liquid release pathway. Removal of tritium is performed by operation of the Boric Acid Concentrator (BAC) In the release mode.Comparison of PVNGS annual tritium curies released to other utilities should be made only after summing both liquid and gaseous tritium curies released.10.5 Summary Dose for 2006 was primarily due to the release of tritium. Tritium production is approximately 1000 curies per Reactor Unit per year. In order to control plant tritium concentrations, tritium releases should match tritium production.

For 2006, PVNGS released a total of 1750 curies of tritium (see Table 39).Total dose from releases from all three Units for the year 2006 were less than year 2005 mainly due to 300 less curies of tritium being released.18 PVNGS ARERR 2006 Table 1: Evaporation Pond Data Evaporation Pond 1 Quarter I Quarter 2 Quarter 3 Quarter 4 Year Historical volume of 3.09E+11 8.50E+11 8.50E+11 3.09E+11 water evaporated (ml)Tritium Concentration 1.91E-06 1.79E-06 2.14E-06 1.17E-06 (uCil/cc)Tritium Curies 5.90E-01 1.52E+00 1.82E+00 3.62E-01 4.29E+00 Evaporation Pond 2 Quarter 1 Quarter 2 Quarter 3 Quarter 4 Year Historical volume of 2.89E+11 7.96E+11 7.96E+11 2.89E+11 water evaporated (ml)Tritium Concentration 1.90E-06 2.14E-06 2.04E-06 8.83E-07 (uCi/cc)Tritium curies 5.49E-01 1.70E+00 1.62E+00 2.55E-01 4.13E+00 Dose (mRem) Quarter I Quarter 2 Quarter 3 Quarter 4 Year Pond 1 8.19E-03 2.11E-02 2.52E-02 5.01E-03 5.95E-02 Pond 2 7.62E-03 2.36E-02 2.25E-02 3.54E-03 5.73E-02 Total 1.58E-02 4.47E-02 4.77E-02 8.55E-03 1.17E-01 Table 2: Batch Release Data All times are in hours Unit I Unit 2 Unit 3 January -June Number of batch releases 34 24 41 Total time period for batch releases 2439.10 314.46 1679.76 Maximum time period for a batch release 177.92 147.02 168.00 Average time period for a batch release 71.74 13.10 40.97 Minimum time period for a batch release 0.80 1.30 0.01 July -December Number of batch releases 33 43 30 Total time period for batch releases 1064.98 1801.02 522.38 Maximum time period for a batch release 165.90 168.00 162.10 Average time period for a batch release 32.27 41.88 17.41 Minimum time period for a batch release 0.34 0.04 0.07 January -December Number of batch releases 67 67 71 Total time period for batch releases 3504.08 2115.48 2202.14 Maximum time period for a batch release 177.92 168.00 168.00 Average time period for a batch release 52.30 31.57 31.02 Minimum time period for a batch release 0.34 0.04 0.01 19 PVNGS ARERR 2006 Table 3: Units 1, 2 & 3 Gaseous Effluents Average Lower Limit Of Detection gCi/cc Nuclide Continuous Batch Nucdide Continuous Batch Antimony-122 2.20E-13 1.90E-11 Argon-41 4.50E-08 4.50E-08 Antimony-124 8.40E-14 1.70E-11 Krypton-85 7.40E-06 7.40E-06 Barium-140 3.40E-13 5.70E-11 Krypton-85m 2.20E-08 2.20E-08 Bromine-82 3.30E-13 1.40E-11 Krypton-87 5.70E-08 5.70E-08 Cerium-141 8.70E-14 3.10E-11 Krypton-88 7.40E-08 7.40E-08 Cerium-144 3.60E-13 6.50E-11 Xenon-125 2.20E-08 2.20E-08 Cesium-134 1.OOE-13 2.60E-11 Xenon-127 2.10E-08 2.10E-08 Cesium-137 8.10E-14 1.70E-11 Xenon-131m 9.1OE-07 9.o10E-07 Cesium-138 5.20E-10 7.30E-10 Xenon-133 6.30E-08 6.30E-08 Chromium-51 6.90E-13 1.40E-10 Xenon-133m 1.90E-07 1.90E-07 Cobalt-58 8.50E-14 1.70E-11 Xenon-135 2.OOE-08 2.OOE-08 Cobalt-60 1.OOE-13 1.90E-11 Xenon-135m 8.90E-08 8.90E-08 Iron-59 1.70E-13 3.20E-11 Xenon-138 2.OOE-07 2.OOE-07 Lanthanum-140 2.80E-13 2.1OE-11 Iodine-131 8.OOE-14 7.OOE-12 Manganese-54 8.30E-14 1.70E-1I Iodine-132 6.60E-12 1.90E-11 Molybdenum-99 2.40E-13 2.80E-11 Iodine-133 4.70E-13 1.10E-11 Niobium-95 8.70E-14 1.80E-11 Iodine-134 5.90E-11 8.20E-11 Rubidium-88 1.90E-08 1.90E-08 Iodine-135 7.OOE-12 5.50E-11 Ruthenium-103 7.40E-14 1.50E-11 Strontium-89 2.15E-15 (1)Strontium-90 5.60E-16 (1)Tellurium-123m 6.60E-14 1.50E-11 Tritium 3.80E-07 3.80E-07 Zinc-65 1.90E-13 3.80E-11 Zirconium-95 1.80E-13 4.10E-11 Gross Alpha 3.60E-15 (1)(1) Not required for batch releases.20 PVNGS ARERR 2006 Table 4: Unit 1 Gaseous Effluents

The joint frequency distribution (JFD) tables represent the fre-quency, in terms of the number of observations, that a particular wind speed, wind direc-tion, and stability category occurred simultaneously.

On a quarterly, semiannual and annual basis, the JFDs were produced for 35-foot wind speed and wind direction by atmo-spheric stability class corresponding to the seven Pasquill stability categories, and for wind speed and wind direction for all stability classes combined.

Atmospheric stability was classified per Regulatory Guide 1.23, using the 200-foot to 35-foot temperature difference (delta T).In accordance with NUREG-0133, the batch releases for the year were considered as"long term," since the batch releases are sufficiently random in both time of day and dura-tion. Consequently, the JFDs for the batch releases for all quarters are the same as for the continuous releases.Discussion A summary of 2006 Joint Frequency Distribution (JFD) shows a somewhat typical, but variable year. Of the 8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br /> available, 106 hours0.00123 days <br />0.0294 hours <br />1.752645e-4 weeks <br />4.0333e-5 months <br /> of data were lost for a 98.8% data recovery.

The majority of the data lost occurred during a calibration in March 2006.The average 35 foot wind speed was 6.5 mph. Distribution of directions was spread over the compass with a predominant direction (3 sectors of 22.5 degrees each) centered on the southwest.

(31.7%) A secondary maximum of three sectors centered on the north contained 28.0% of the total. Southwesterly flow winds averaged higher speeds with the most frequent speeds at 7.0 mph and 10.0 mph. With the northerly directions, the highest frequency occurred at 4.0 mph.Stability class summary: Overall stable conditions (E,FG) dominated, with extremely stable (G) conditions occurring during 28.0% of the hours.Stability class E, F, GQ (stable categories) 58.5%.Stability class G, (extremely stable) 28.0%.Stability class A, B, C, (unstable categories) 23.9%.Stability class D, (neutral category) 17.6%.Light northerly flow is most likely for stable conditions, while unstable atmospheres are usually associated with faster southwesterly winds. This distribution is typical of moderate altitude dry climates.67 PVNGS ARERR 2006 ARIZONA PUBLIC SERVICE CO. -PALO VERDE NUCLEAR GEN4ERATIRG-STATION JOINT FREQUENCY DISTRIBUTION FOR THE PERIOD 1/01/2006 TO 3/31/2006.1ST QRTR *.*STABILITY CLASS A STABILITY BASED ON: DELTA T BETWEEN 200.0 AND 35.0 FEET WIND MEASURED AT: 35.0 FEET WIND THRESHOLD AT: .75 MPH JOINT FREQUENCY DISTRIBUTION OF WIND SPEED AND DIRECTION IN HOURS AT 35.00 FEET SPEED (MPH) N NNE ME ENE B ESE SE SSE S SSW SW WSW W WNW NW NNW TOTAL CALM 0.76- 1.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1.51- 2.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2.51- 3.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3.51- 4.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 4.51- 5.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5.51- 6.50 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 1 6.51- 8.50 0 1 3 2 1 1 0 0 2 4 2 2 0 0 0 0 18 8.51-11.50 0 0 2 1 2 0 0 0 1 4 13 0 1 0 1 0 25 11.51-14.50 1 0 0 2 0 0 0 0 0 1 7 1 1 2 2 0 17 14.51-20.50 0 0 0 0 0 0 0 0 0 0 B 9 2 7 0 1 27>20.50 0 0 0 0 0 0 0 0 0 0 3 2 1 0 0 0 6 TOTAL 1 1 6 5 3 1 0 0 3 9 33 14 5 9 3 1 94 STABILITY CLASS B SPEED (MPH) N NNE NE ENS E ESE SE SSE S SSW SW WSW M WNW NW MW TOTAL CALM 0.76- 1.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1.51- 2.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2.51- 3.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3.51- 4.50 0 0 0 0 1 0 0 0 0 1 0 0 0 0 0 0 2 4.51- 5.50 0 0 0 0 1 1 0 1 2 1 0 1 2 0 0 0 9 5.51- 6.50 0 1 4 0 0 0 0 1 5 3 2 4 0 0 0 0 20 6.51- 8.50 0 1 1 1 2 2 0 4 4 1 5 7 1 0 1 0 30 8.51-11.50 0 0 1 6 4 0 1 0 1 2 9 2 3 1 2 1 33 11.51-14.50 0 0 0 3 2 0 0 0 0 0 4 1 1 2 2 0 15 14.51-20.50 0 0 0 1 0 0 0 0 0 0 3 1 1 0 0 1 7>20.50 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 1 TOTAL 0 2 6 11 10 3 1 6 12 8 23 17 8 3 5 2 117 STABILITY CLASS C SPEED (MPH) N NNE ME ENE E ESE SE SSE S SSW SM WIN W NNW NM MW TOTAL CALM 0.76- 1.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1.51- 2.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2.51- 3.50 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 1 3.51- 4.50 0 4 2 0 1 0 1 2 0 2 5 4 0 0 1 0 22 4.51- 5.50 0 1 5 2 5 0 0 1 4 3 1 1 7 0 0 0 30 5.51- 6.50 1 1 2 3 0 1 0 0 4 4 8 1 1 0 1 0 27 6.51- 8.50 1 2 6 6 0 1 0 1 4 2 4 4 1 0 0 0 32 8.51-11.50 0 0 3 3 1 2 0 0 1 3 4 4 0 0 0 1 22 11.51-14.50 0 0 0 0 2 0 0 0 0 0 2 0 1 3 0 0 8 14.51-20.50 0 0 0 2 2 0 0 0 0 0 0 3 2 0 0 0 9>20.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 TOTAL 2 8 18 16 11 4 1 4 13 15 24 17 12 3 2 1 151 68 PVNGS ARERR 2006 ARIZONA PUBLIC SERVICE CO. -PALO VERDE NUCLEAR GENERATING STATION JOINT FREQUENCY DISTRIBUTION FOR THE PERIOD 1/01/2006 TO 3/31/2006-1ST QRTR ...STABILITY CLASS D STABILITY BASED ON: DELTA T BETWEEN 200.0 AND 35.0 FEET WIND MEASURED AT: 35.0 FEET WIND THRESHOLD AT: .75 MPH JOINT FREQUENCY DISTRIBUTION OF WIND SPEED AND DIRECTION IN HOURS AT 35.00 FEET SPEED (MPH) N NNE NE ENE E ESE SE SSE S SSW SW WSW W WNW NW NNW TOTAL CALM.76- 1.50 0 0 0 0 0 0 0 0 0 0 0 0 1.51- 2.50 2 0 1 0 0 0 1 4 2 1 2 3 2.51- 3.50 3 2 4 7 1 3 6 9 14 10 7 4 3.51- 4.50 2 3 5 5 2 1 2 4 15 7 5 5 4.51- 5.50 2 3 1 3 0 0 2 1 8 6 7 6 5.51- 6.50 0 4 3 7 1 0 1 0 2 6 6 4 6.51- 8.50 0 1 4 5 1 0 1 2 1 6 6 7 8.51-11.50 0 0 2 8 3 2 0 0 2 0 6 5 11.51-14.50 0 0 0 4 4 0 1 0 0 2 & 2 14.51-20.50 0 0 0 4 9 0 0 0 0 0 2 2>20.50 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 4 3 3 27 3 6 6 0 85 1 2 1 4 64 2 1 0 1 43 1 0 3 0 3B 2 3 2 0 41 2 2 1 0 33 1 0 0 0 iB 0 0 0 1 is 0 0 0 0 0 TOTAL 9 13 20 43 21 6 14 20 44 36 45 38 13 iB 16 9 367 STABILITY CLASS E SPEED (MPH)N NNE NE ENE E ESE SE SSE S SSW SW WSW N WNW NW NNW TOTAL CALM.76- 1.50 0 0 1.51- 2.50 1 0 2.51- 3.50 2 1 3.51- 4.50 4 2 4.51- 5.50 4 4 5.51- 6.50 0 1 6.51- 8.50 0 1 8.51-11.50 0 0 11.51-14.50 0 0 14.51-20.50 0 0>20.50 0 0 0 0 0 0 0 2 2 1 0 0 0 2 0 0 0 2 0 2 0 0 0 0 0 0 0 2 3 1 0 0 0 1 2 0 1 4 4 0 0 1 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 2 1 1 0 4 2 0 1 1 2 5 3 0 0 3 2 4 0 2 2 4 1 1 3 9 17 4 0 1 9 15 8 0 0 1 4 6 0 0 0 0 2 0 0 0 0 0 0 0 0 5 2 1 6 3 5 2 3 4 4 0 1 0 0 2 7 4 2 5 5 4 1 3 4 2 0 2 0 0 0 0 0 0 1 19 3 29 2 33 0 22 0 19 0 52 0 56 1 21 0 6 0 0 TOTAL 11 9 10 13 6 0 2 3 7 31 51 29 32 20 25 7 256 STABILITY CLASS F SPEED (MPH)N NNE NE EN E ESE SE SSE S SSW SW WSW W WNW NW NNW TOTAL CALM 0.76- 1.50 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 2 1.51- 2.50 2 0 2 0 0 1 1 0 0 0 1 2 1 5 2 3 20 2.51- 3.50 4 0 2 0 2 0 0 1 1 3 2 2 4 3 7 4 35 3.51- 4.50 5 1 4 1 2 0 0 0 0 3 3 3 2 5 7 7 43 4.51- 5.50 7 4 0 0 0 0 0 0 1 4 5 6 4 6 2 3 42 5.51- 6.50 1 2 1 0 0 0 0 0 2 2 5 1 8 4 6 0 32 6.51- 8.50 0 2 1 0 0 0 0 0 0 5 19

The radionuclides considered in the dose calcula-tions were Tritium, Iodine-131, Iodine-1 32, Iodine-1 33, Iodine-1 35, all noble gases, and particulates having a half-life greater than eight days and for which dose factors are contained in NUREG-01 72. Locations selected for individual dose calculations included for each sector, the site boundary, and within five miles, if present, the nearest residence, the nearest garden, and the nearest milk animal. GASPAR Implements the radiological dose models of Regulatory Guide 1.109 to determine the radiation exposure to man from four principal atmospheric exposure pathways: plume, ground deposition, Inhalation, and Ingestion.

Doses to the maximum individual and the population were calculated as a function of age group and pathway for significant body organs.Table 43 presents the doses on a quarterly, semiannual and annual basis for the Energy Informa-tion Center. An occupancy factor of 1.0 (implying continuous occupancy over the entire year) was considered for the Energy Information Center and the exposure pathways considered to calculate its doses were plume, ground deposition, and inhalation.

Table 44 presents the population dose.Table 45 summarizes the individual doses and compares the result to PVNGS ODCM Require-ment limits. The site boundary and residence locations for which data are presented represent the highest annual doses.Based on results obtained by placing TLDs on the site boundary in each sector, the net dose for this reporting period, from direct-radiation, (plume and ground deposition) from all three units was indistinguishable from preoperational values of 8 -14 liR/hr (17 -30 mR/Std Qtr).There were no liquid effluents associated with the operation of this facility.90 PVNGS ARERR 2006 Dose Calculation Models The GASPAR computer code was used to evaluate the radiological consequences of the routine release of gaseous effluents.

GASPAR implements the dose calculational methodologies of Regu-latory Guide 1.109, Revision 1.Source terms for each quarter are combined with station-specific demographic data and each quarter's atmospheric diffusion estimates for gaseous dose calculations.

Atmospheric diffusion estimates are generated by the XOQDOQ computer code using onsite meteorological data as Input. Additional input to GASPAR includes the following site-specific data: 0 to 5 mile nearest residence, milk animal and garden in each of the 16 compass sectors, based on the 2006 Land Use Census.0 to 10 mile population distribution based on the State of Arizona -Maricopa County, Offsite Emergency Response Plan for Palo Verde Nuclear Generating Station, December 2006, Survey Information.

The 10 to 50 mile population distribution from the PVNGS UFSAR, Figure 2.1-11.The population distribution of metropolitan Phoenix greater than 50 miles from PVNGS, based on the 1980 federal census results, is conservatively included in the 40 to 50 mile sectors (NE=123; ENE=140,097; E=621,130; ESE=8,392).

Absolute humidity of 6.0 g/m 3 from the PVNGS UFSAR, Table 2.3-16.The fraction of the year that vegetables are grown (0.667) from the PVNGS ER-OL, Section 2.1.3.4, Table 2.1-8.The fraction of daily feed derived from pasture while on pasture (0.35) and length of grazing season for milk animals beyond 5 miles (0.75) from the PVNGS ER-OL, Section 2.1.3.4.3.
