PVNGS Semi-Annual Operating Report for July December 1987 Measurement and Approximations of Total Radioactivity in Gaseous Effluents.
For continuous releases,'ampling is in accordance with PVNGS Technical Specification Table 4.11-2. 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. For. containment purges, the noble gas con-centration is adjusted to account for decreases or increases in con-centration 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. An average LLD for each radionuclide is provided in Table Al.

PVNGS Semi-Annual Operating Report for July December 1987 8.0 Effluents and Solid Wastes 8.1 Gaseous Effluents The gaseous effluents for the third and fourth quarters are included in Tables A2, A3, A5, A6, A8, and A9. Included in these tables are summaries of the effluents and estimated total error.
8.2 Liquid Effluents 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 the concentrations specified in Technical Specification 3.11.1.1. In addition, PVNGS has imposed a limit of 3 x 10 3 pCi/ml for tritium in tanks released to the evaporation pond. This is the maximum permis-sible concentration for unrestricted areas for tritium in water from 10CFR20 Appendix B. The evaporation pond was monitored in accordance with Technical Specification 3.12.1. During this report period, the analyses showed tritium concentrations in water to be less than 1.5 x 10-6 pCi/ml.
The results of the second quarter 1987 Strontium-89 and Strontium-90 analyses for continuous mode releases were less than, the Lower Limit of Detection. The gaseous effluent and dose summaries are therefore correct as reported in the January June, 1987 Semi-Annual Report.

PVNGS Semi-Annual Operating Report for July December 1987 JOINT FREQUENCY DISTRIBUTION TABLES 0 The tables presented in this section are results obtained from processing the hourly meteorological data collected at the Palo Verde Nuclear Generating Station for 1987. 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, semi-annual and 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 third and fourth quarters for 1987 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 July - December 1987 GASEOUS EFFLUENT* DOSE CALCULATION ses 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 and 2 during the third and fourth quarters, and from Unit 3 in the fourth quarter. 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 third quarter only since the fourth 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 milk, goat 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 C8.
.Table Cl presents the doses on a quarterly and semi-annual basis for the highest exposed location on the site boundary, the maximum individual in the general public and the Visitors Center. The site boundary and residence**
ocations for which data are presented represent the highest annual doses.
occupancy factor of 1.0 (implying continuous occupancy over the entire year) was considered for the Visitor Center and the exposure pathways considered to calculate its doses were plume, ground deposition, and inhalation. Table Cl also presents the total dose as defined in Technical Specification 3.11.4.
Table C2 presents the population doses for the year 1987. 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.
Where were no liquid effluents associated with the operation of this

- From Table Cl.
- These control location doses are imparted via three principal atmospheric pathways: plume, ground exposure and inhalation.
The hypothetical site boundary location doses presented in Tables A4, A7 and A10 of Appendix A, are based on the ODCM, and also include vegetable, milk and meat ingestion contributions. The highest organ dose is to the child' thyroid resulting from exposure in the South Sector at 2.96, 2.80 and 2.64 miles from Units 1, 2, and 3, respectively.
Technical Specification 3.11.4 has higher limits than Technical Specification 3.11.2.3 and therefore the percent of limits are more conservative based on Technical Specification 3.11.2.3 than on Technical Specification 3.11.4.

PVNGS Semi-Annual Operating Report for July - December 1987 DOSE CALCULATXON 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 XOQDOQ computer code using onsite meteorological data as input. Doses 'for the semi-annual period are the summation of the quarterly doses. Additional input to GASPAR includes the following site-specific data:
o 0 to 5 mile land use census conducted in December 1987. The follow-ing changes in land use were identified between December 1986 and December 1987; addition of a residence within the east-northeast sector and 2.7 miles from Unit 2 and a residence located within the south sector and 2.8 miles from Unit 2.
o 0 to 5 mile population distribution based on the land use census conducted June-August, 1984.
o 5 to 50 mile population distribution from PVNGS ER-OL Figure 2.1-6.
o The population distribution of metropolitan Phoenix greater than 50 miles from PVNGS, based on the 1980 census results, were conserva'-
tively included in the 40 to 50 mile sectors.
o Absolute humidity of 6.0 g/m3 from PVNGS ER-OL Table 2.3-34.
o The fraction of the year that vegetables are grown (0.667) from PVNGS ER-OL Section 2.1.3.4.
- o. 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.
o The only milk animal (goat) located within 5 miles from PVNGS was fed fifty percent on stored feed and the other fifty on pasture grass during 1987, based on the land use census conducted in December 1987.
o 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 1.
