C~PVNGS Technical S ecification 3.11.2.3 The dose to a MEMBER OF THE PUBLIC from Iodine-131, Iodine-133, Tritium, and all radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents released, from each reactor unit, to areas at and beyond the SITE BOUNDARY shall be limited to the following:

~During any calendar quarter: Less than or equal'to 7.5 mrems to any organ and,~During any calendar year: Less than or equal to 15 mrems to any organ.d.PVNGS Technical S ecification 3.11.2.4 The GASEOUS RADWASTE SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM shall be used to reduce radioactive materials in gaseous waste prior to their discharge when the projected gaseous effluent air doses due to gaseous effluent releases, from each reactor unit, from the site when averaged over 31 days, would exceed 0.2 mrad for gamma radiation and 0.4 mrad for beta radiat'ion.

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.1.3 Total Dose a~PVNGS Technical S ecification 3.11.4 The annual (calendar year)dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to 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 1.2a.of this report.A3 I I il r S Il PVNGS Semi-Annual Operating Report for January-June 1989 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 MEASUREMENT AND APPROXIMATIONS OF TOTAL RADIOACTIVITY IN GASEOUS EFFLUENTS For continuous releases, sampling is in accordance with PVNGS Technical Specification Table 4.11-2 (Units 1, 2 and 3).Particulate and iodine radionuclides are sampled continuously at the three exhaust points.The particulate filters and charcoal cartridges are exchanged for analysis 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 Technical Specification Table 4.11-2 (Units 1, 2 and 3).For containment purges, the noble gas concentration is 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.The Lower Limit of Detection (LLD)of a measurement system is defined in Table 4.11-2 of the PVNGS Technical Specifications (Units 1, 2 and 3).An average LLD for each radionuclide is provided in Table Al.5.0 BATCH RELEASES 5.1 Gaseous Unit 1<<Unit 2~'nit 3>'<Number of batch releases: Total time period for batch releases: Maximum time period for a batch release: Average time period for a batch release: Minimum time period for a batch release: 51 3219.42 168.00 63.13 0.58 37 1063.68 151.88 28.75 0.06 57 4575.80 168.00 80.28 0.17 All times are in hours 5.2 Liquid None A4 l I el I p PVNGS Semi-Annual Operating Report for January-June 1989 6.0 ABNORMAL RELEASES Unit 3 had two (2)unplanned releases involving main steam exhausting to the atmosphere.

A total of 2.31E+00 curies was released;this is included in Tables A8 and A9.The corresponding meteorological data is included in Appendix B.7.0 OFFSITE DOSE CALCULATION iiIAVUAL (ODCM)AND PROCESS CONTROL PROGRAM (PCP)REVISIONS There were no revisions to the ODCM or the PCP.There were no major changes to the radwaste systems.8.0 EFFLUENTS AND SOLID WASTES 8.1 Gaseous Effluents The gaseous effluents for the first and second quarters are included in Tables A2 through A10.Included in these tables are summaries of the effluents and estimated total error.8~2 Liquid Ef fluents There were no liquid effluents from the PVNGS site.8.3 Solid Waste Solid waste shipments are summarized in Table A12.9.0 MISCELLANEOUS INFORMATION Releases made to the evaporation pond have been limited at the tank to'he concentrations specified in PVNGS Technical Specification 3.11.1.1.In addition, PVNGS has imposed a limit of 3 x 10 pCi/ml for tritium in tanks released to the evaporation pond.This is the maximum permissible concentration for unrestricted areas for tritium in water from 10CFR20 Appendix B.The evaporation ponds were monitored in accordance with PVNGS Technical Specification 3.12.1 (Units 1, 2 and 3).During this report period, the analyses showed tritium concentrations in water to be less than or equal to 1.2 x 10 6 pCi/ml.The results of the fourth quarter 1988 Strontium-89 and Strontium-90 analyses for continuous mode releases, which were not available at the time the July-December, 1988 Semi-Annual Report was written, were determined to be less than the Lower Limit of Detection.

The gaseous effluent and dose summaries are therefore correct as reported in the July-December, 1988 Semi-Annual Report.A5 i(l, 0 0 PVNGS Semi-Annual Operating Report for January-June 1989 PVNGS TABLE Al UNITS 1, 2, AND 3 GASEOUS EFFLUENTS-AVERAGE LOWER LIMIT OF DETECTION NUCLIDE pCi/cc CONTINUOUS BATCH ARGON 41 KRYPTON 85 KRYPTON 85m KRYPTON 87 KRYPTON 88 XEiVON 131m XEiVON 133 XENON 133m XENON 135 XENOiV 135m XENON 138 IODIiVE 131 IODINE 132 IODINE 133 IODINE 134 IODINE 135 ANTIMONY 122 ANTIMONY 124 BARIUiM 140 BROMINE 82 CERIUM 141 CERIUM 144 CESIUM 134 CESIUM 137 CESIUM 138 COBALT 57 COBALT 58 COBALT 60 IRON 59 LANTHANUM 140 MANGANESE 54 MOLYBDEiVUM 99 NIOBIUM 95 RUBIDIUM 88 RUTHENIUM 103 STRONTIUM 89 STRONTIUM 90 TRITIUM ZINC 65 GROSS ALPHA 1.70E-OS 5.50E-06 2.10E-08 4.90E-08 9.10E-08 3.90E-07 6.00E-08 1.10E-07 2.40E-08 5.10E-07 2.30E-06 3.70E-14 2.20E-14 2.60E-14 3.80E-14 9.60E-14 3.50E-14 7.70E-14 1.10E-13 1.90E-14 3.30E-14 1.40E-13 1.60E-14 2.40E-14 1.20E-13 1.70E-14 2.60E-14 3.00E-14 3.50E-14 3.00E-14 2.70E-14 2.30E-13 2.40E-14 1.20E-12 2.20E-14 2.10E-15 5.60E-16 5.00E-07 5.90E-14 6.00E-15 1.70E-08 5.50E-06 2.10E-08 4.90E-08 9.10E-08 3.90E-07 6.00E-08 1.10E-07 2.40E-08 5.10E-07 2.30E-06 1.50E-11 1.60E-12 1.00E-11 3.20E-12 3.80E-11 1.40E-12 3.60E-12 4.30E-11 9.60E-13 1.30E-11 5.80E-11 6.30E-12 9.60E-12 3.80E-12 7.10E-13 1.00E-11 1.20E-11 1.40E-11 1.20E-11 1.10E-11 9.20E-11 9.80E-13 3.00E-11 1.50E-12 1C fC 5.00E-07 2.30E-11 Not required for batch releases.A6 I i~i I PVNGS Semi-Annual Operating Report for January-June 1989 Table A2 PVNGS UNIT 1 1989 GASEOUS EFFLUENTS-SUI'2'IATION OF ALL RELEASES UNIT QUARTER 81 QUARTER N2 EST.TOTAL ERROR/<<A.Fission&activation gases 1.Total release 2.Average release rate for eriod 3.Percent of technical s ecification limit Ci/sec 7.26E+01 NA<<<<1.88E+00 NA<<<<B.Iodines 1.Total Iodine-131 2.Average release rate for eriod 3.Percent of technical s ecification limit Ci/sec 4 6.51E-05 NA<<<<1.18E-05 V<A<<<<C.Particulates 1.Particulates with half-2.Average release rate for eriod 3.Percent of technical s ecification limit Ci/sec 1.69E-06 NA<<<<1.02E-05 NA<<<<4.Gross Alpha radio-activit Ci LLD LLD D.Tritium 1.Total release 2.Average release rate for eriod 3.Percent of technical s ecification limit Ci/sec 1.46E+01 NA<<<<3.13E+00 NA<<<<4 29<<Estimated total error methodology is presented in Table All.<<<<See Table A4 for percent of technical specification limits.A7

On a quarterly and semi-annual basis, the JFDs were produced for 35-foot wind speed and wind direction by atmospheric 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 first and second quarters for 1989 were considered as"long term", since for each quarter, the sum of the batch release periods for each unit exceeded 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br />.Consequently, the JFDs for the batch releases for both quarters are the same as for the continuous releases.B2 1~f PVNGS Semi-Annual Operating Report for January-June 1989 Table Bl JFDs of 35-Foot Mind Versus Delta T January-March 1989 B3

Strontium-89 and Strontium-90 were considered for the first quarter only since the second quarter results were not available.

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.

The ingestion pathways considered were cow milkgoat milk, meat, and vegetables.

Doses to the maximum individual and the population were calculated as a function of age group and pathway for, significant body organs.Assumptions and data sources used for input to the GASPAR code are described on page C6.Table Cl presents the doses for the first two quarters and the first semi-annual period of 1989 for the highest exposed location on the site boundary and the maximum individual in the general public.The site boundary and residence locations for which data are presented represent the highest annual doses.Table C2 presents the population doses for the first two quarters, and the first semiannual period of 1989.Table C3 summarizes the individual doses and compares the result to PVNGS Technical Specification limits.Based on results obtained by placing TLDs on the site boundary in each sector, the net annual dose from direct-radiation, plume and ground deposition from all three units was determined to be zero.<<There were no liquid effluents associated with

ap4 g+P C k l 1I V PVNGS Semi-Annual Operating Report for January-June 1989 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 l.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 XOgDOQ computer code using onsite meteorological data as input.Doses for the semi-annual period are the summation for the quarterly doses.Additional input to GASPAR includes the following site-specific data:~0 to 5 mile nearest residence, milk animal and garden in each of 16 compass sectors, based on the 1988 Land Use Census.~0 to 5 mile population distribution based on the Land Use Census conducted June-August, 1984.~5 to 50 mile population distrubution from PVNGS ER-OL Figure 2.1-6.~The population distribution of metropolitan Phoenix greater than 50 miles from PVNGS, based on the 1980 federal census results, was conservatively included in the 40 to 50 mile sectors.~Absolute humidity of 6.0 g/m from PVNGS ER-OL Table 2.3-34.~The fraction of the year that vegetables are grown (0.667)from PVNGS ER-OL Section 2.1.3.4.~The fraction of daily feed derived from pasture while on pasture and length of grazing season for milk animals beyond 5 miles (0.35 and 0.75)from PVNGS ER-OL Section 2.1.3.4.~The only milk animal (goats)located within 5 miles from PVNGS was fed fifty percent on stored feed and the other fifty on pasture grass during 1988, based on the 1988 Land Use Census.~The fraction of daily feed derived from pasture while on pasture and length of grazing season for meat animals (0.05 and 0.25)from PVNGS ER-OL Section 2.1;3.4.Other values used for input to GASPAR are default values from Regulatory Guide 1.109, Revision l.C6 l<u,'$~'a~J'P ly li 0 lf1
