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.

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 concentrations specified in PVNGS Technical Specification to'he 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.

PVNGS Semi-Annual Operating Report

~ I Jl for January June 1989 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 January June 1989. 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. 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.

PVNGS Semi-Annual Operating Report for January June 1989 GASEOUS EFFLUENT)'c DOSE CALCULATION 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. Gaseous effluents were released from Units 1, 2 and 3 during the first and second quarters. 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. 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 the operation of this facility.

<<From Table Cl.

<<<<These control -location doses are imparted via three principal atmospheric pathways: plume, ground exposure and inhalation.

The highest organ dose is to the teen thyroid resulting from exposure at a residence 4.55 miles SSM from Unit 1, 4.37 miles S from Unit 2, and 4.22 miles S from Unit 3. Technical Specification 3.11.4 has higher limits than Technical Specification 3.11.2.3 and therefore the percent of limits are more conservative e based on Technical Specification 3.11.2.3 than on Technical Specification 3.11.4.

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.
