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 ( ) 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 8

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.

5.0 BATCH RELEASES 5.1 Gaseous.

Batch release durations are presented in Table 2.

5.2 Liquid None.

6.0 ABNORMAL RELEASES 6.1 None.

7.0 OFFSITE DOSE CALCULATION MANUAL AND PROCESS CONTROL PROGRAM (PCP)

REVISIONS 7.1 There were no revisions to the Offsite Dose Calculation Manual (ODCM) in 2018.

7.1 There were no revisions to the Process Control Program (PCP) in 2018.

8.0 EFFLUENTS AND SOLID WASTES 8.1 Gaseous Effluents Gaseous effluent information is presented in Table 1 through Table 41. Included in these tables are summaries of the effluents and estimated total error.

8.2 Liquid Effluents 9

There were no liquid effluents releases beyond the site boundary from PVNGS 8.3 Solid Waste Solid Waste Shipments are summarized in Appendix A.

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. Evaporation Pond One is approximately 261 acres which is divided into three segments: Pond 1A (131 acres), Pond 1B (77.5 acres) and Pond 1C (52.5 acres). This equates to 3.22E+11 cc evaporated from Pond One for each of the first and fourth quarters and 8.85E+11 cc evaporated for each of the second and third quarters. Evaporation Pond Two is approximately 232 acres which is divided into three segments: Pond 2A (117 acres), Pond 2B (87 acres) and Pond 2C (30 acres).

The amount evaporated from Pond Two is 2.86E+11 cc for each of the first and fourth quarters and 7.87E+11 cc for each of the second and third quarters. Pond 2C is a sludge pond and typically not sampled.

Evaporation Pond Three is constructed of two smaller ponds of 90 acres each (3A and 3B). The amount evaporated from each section of Pond Three is 2.20E+11 cc for each of the first and fourth quarters and 6.04E+11 cc for each of the second and third quarters.

Using a site boundary X/Q of 5.0E-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 set points are based on an assumed one percent failed fuel source term. The current method used for the set point values are more reliable than basing the set points upon the constantly varying values of 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.

11

9.5 MAJOR CHANGES TO THE RADIOACTIVE WASTE SYSTEMS (liquid, gaseous, and solid).

9.5.1 None.

9.6 Sample results from the groundwater wells that are not described in the ODCM as part of the REMP (NEI 07-07, Industry Groundwater Protection Initiative, August 2007), are included in Appendix D. This initiative provides added assurance that ground water will not be adversely affected by PVNGS operations.

There were no NEI 07-07 reportable leaks or spills. There were no positive sample results (all results below the Lower Limit of Detection).

Carbon-14 is not a new power plant emission. Because the overall quantity of radioactive releases has steadily decreased due to improvements in power plant operations, carbon-14 may now qualify as a "principal radionuclide" under revised federal regulatory guidance. The levels of other releases have declined, so carbon-14 releases, expressed as a percentage of total releases, have the potential to achieve "principal radionuclide" status (anything greater than one percent of overall radioactivity in effluents) per updated federal regulatory guidance.

The radiation dose to the public from carbon-14 is much lower than regulatory limits and has been a very small contributor to the total radiation dose that individuals receive each year from natural and manmade sources. Studies by the United Nations Scientific Committee on the Effects of Atomic Radiation, the National Research Councils BEIR VII study group and the National Council on Radiation Protection and Measurements all show that the risk associated with low-dose radiation from natural and man-made sources, including nuclear power plants, is negligible.

Radiation dose is measured in units of millirem. The average American is exposed to 620 millirem of radiation every year. Approximately 311 millirem of this is attributed to natural sources. The majority of the remaining dose (approximately 300 millirem) comes from medical procedures such as CAT scans. Less than one-tenth of a percent of all radiation exposure is from nuclear facilities2.

The PVNGS calculated production of carbon-14 is 18.5 Curies per operating cycle (500 days) or 13.5 curies per year. The 13.5 curies will be divided equally between each quarter (3.38 curies per reactor). The estimated C-14 activity is included in all of the inhalation and ingestion dose calculations.

10.5 Tritium 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.

10.6 Dose Summary Dose for 2018 was primarily due to the release of tritium. Tritium production is estimated to be 1000 curies per Reactor Unit per year. In order to control plant tritium concentrations, tritium releases should match tritium production. For 2018, PVNGS released a total of 2,330 curies of tritium (see Table 39).

10.7 Detailed Release Data CR 18-06915 was generated and included in the 2017 PVNGS ARERR in order to evaluate the potential releases due to the loss of pressure from the waste gas decay tanks (WGDTs). Annual Site boundary doses were estimated for 2015 through 2018. No significant pressure losses contributing to atmospheric release were suspected in 2015.

All estimated calculations below are making the conservative assumption that tanks are leaking to atmosphere. It is suspected, based upon observing tank pressures, that the leak pathway is back to the surge tank and not to atmosphere. Leaks from the Gaseous Radioactive (GR) Waste system are detected via a permanently installed radiation monitor, RU-15. RU-15 measures the ambient air concentration from all cubicles from the GR system. Ambient air from the GR system cubicles are processed through the Plant Vent which is monitored by the Plant Vent monitor, RU-143. None of the radionuclides identified in the WGDTs contribute to critical organ dose, only to external dose. Gamma and Beta external dose due to potential leaking WGDTs for 2016, 2017, and 2018 are listed in the tables below and are determined to be inconsequential

(<0.0002% of the ODCM limit for beta and gamma external dose each year).

Calculations are based on parameters and methodologies of the ODCM using historical meteorology. Dose is calculated to a hypothetical individual. An Engineering Evaluation (EE 4891667) has been developed in order to detect locations of leaks in the GR system along with an open Action Item (18-13934-003) to fix the leaks as needed.

APPENDIX B: METEOROLOGY 66

JOINT FREQUENCY DISTRIBUTION TABLES The tables presented in this section are results obtained from processing the hourly meteorological data collected at the Palo Verde Nuclear Generating Station for the period of January - December 2018. The joint frequency distribution (JFD) tables represent the frequency, in terms of the number of observations that a particular wind speed, wind direction, and stability category occurred simultaneously. The JFD tables were produced using the wind speed and direction measured at 35 foot elevation. Based on the data collected, the atmospheric stability class corresponding to the seven Pasquill stability categories, as we ll a s t h e 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 duration.

Consequently, the JFDs for the batch releases for all quarters are the same as for the continuous releases.

Discussion A summary of 2018 Joint Frequency Distribution (JFD) shows a typical year. Of the 8760 hours0.101 days 2.433 hours 0.0145 weeks 0.00333 months available, 207 hours0.0024 days 0.0575 hours 3.422619e-4 weeks 7.87635e-5 months of data were lost due to the meteorological tower being out of service for an equipment upgrade. As a result, the effective data recovery for 2018 was 97.6 percent.

The 35-foot mean wind speed was 6.3 mph. South west winds averaged higher speeds with the most frequent speeds between 8.51-11.50 mph.

Stability class summary:

Stability class E and F, (stable categories) 33%.

Stability class G, (extremely stable) 23.09%.

Stability class A, B, C, (unstable categories) 29.2%.

Stability class D, (neutral category) 14.72%.

APPENDIX C: DOSE CALCULATIONS 84

GASEOUS EFFLUENT DOSE CALCULATIONS Doses to the maximum individual and the surrounding population resulting from the release of radioactive material in gaseous effluents from the Palo Verde Nuclear Generating Station were calculated using the GASPAR computer program. The radionuclides considered in the dose calculations were Tritium, Iodine-131, Iodine-132, Iodine-133, Iodine-135, all noble gases, and particulates having a half-life greater than eight days and for which dose factors are contained in NUREG-0172. 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 has been removed as the Energy Information Center (EIC) has been moved offsite.

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 R/hr (17 - 30 mR/Std Qtr).

There were no liquid effluents associated with the operation of this facility.

85

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 Regulatory Guide 1.109, Revision 1.

Source terms for each quarter are combined with station-specific demographic data and each quarters 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 2018 Land Use Census.

0 to 10 mile population from the PVNGS Emergency Plan, Rev 60.

The 10 to 50 mile population distribution from the PVNGS UFSAR, Figure 2.1-12.

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/m3 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.

The fraction of daily feed derived from pasture while on pasture (0.05) and length of grazing season for meat animals (0.25) from the PVNGS ER-OL, Section 2.1.3.4.4.

There were eight (8) sectors containing milk animal (goat or cow) locations within five (5) miles. For calculation purposes these milk animals are assumed to be fed 100% on pasture grass during the year.

Other values used for input to GASPAR are default values from Regulatory Guide 1.109, Rev. 1.
