INTRODUCTION Rancho Seco Nuclear Generating Station (RSNGS) Unit No.1 is located in Sacramento County, California approximately 25 miles southeast of Sacramento and 26 miles north-northeast of Stockton. Rancho Seco Un!! No.1 began commercial operation on April 17,1975. The single l-unit on the RancN Seco site is a pressurized water reactor supplied by Babcock and Wilcox.

L The rated cape',rty is 963 gross megawatts electrical. Because of a public vote on June 6, 1989, the Dir'.nct shutdown the Rancho Seco Nuclear Generating Station and completed defue!!ng cperations on December 8,1989.

This Femiannual Radioactive Effluent Release Report (SRERR) provides a summary of gaseous ano liquid effluent releases made from Rancho Seco during the period Januar) 1 through June I

30,1990. Also presented in this report is the projected radiological impact from these releases end a summary of solid radwaste shipments.

This report has been prepared by the Seciamento Municipal Utility District to meet the I

requirements of Rancho Seco Technical Specification 6.9.2.3. It is presented in a,0*ordance wl'h the format of USNRC Regulatory Guide 1.21. The radiation doses reported in this SRERR are calculated for a hypothetical individual who receives the maximum possible exposure at or I

beyond the Site Boundary.

Releases of radioactivity ir, gaseous and liquiu effluents during this report prood did not exceed the limits of 10 UFR 20 or the nummical guidelines of 10 CFR 50, Appendix 1. A 40 CFR 190 I

dose evaluation is not required because radioactive effluent releases did ne. exceed twice th3 numerical guidelines of 10 CFR 50, Appendix l.

RADIOACTIVE EFFLUENT MONITORING INSTRUMENTATION INOPERABLE FOR GREATER THAN 30 DAYS Liuuld Monitorina Instrunantation The liquid effluent radiation monitor (R15017A) was out of service from the beginning of I

the reporting period until 4/19/90. The monitor was out of service for repair because electronic nnise ar d grounding problems were causing spurious alarms.

Gaseous Monitorina instrumentation Flow element FE.15044, for gaseous effluent radiation monitor R 15044,/ s inoperable wa from the beginning of the reporting period until 3/13/90. Flow element FE.15045, for I

gaseous radiation monitor R 15045, was inoperable from the beginning of the reporting period until 4/19/90. Flow element FE 15546A, for gueous radiation monitor R 15546A, was inoperable from the beginning oi the reportin0 period until 1/8/90. These flow elements remained inoperable because of continual problems with meeting the acceptance criteria of the quarterly surveillance procedure. The flow elements are a thermal anemometer type and produce inconsistent results due to turbulent flow through the effluent exhaust stacks. During periods of flow element inoperability, maximum design flow rates were used in accordance with Technical Specifications. New permanent scaffolding was erected to allow access to the flow elements. Since the completion of the new scaffolding. the flow elements may be removed for laboratory calibration.

CHANGES The Radiological Environmental Monitoring Program (REMP) was revised effective January I

1,1990. The changes removed various sampling locations that are not required by Technical Specifications and added four new control sampling locations. The specific changes are addressed below, by sample type.

1.

Milk One milk sampling location has been deleted, as it was previously identified as an I

Indicator location but did not comply with the Branch Techol%i Pettion's definition o

of such a location.

2.

Fish and invertebrates One additional fish location was establist.tv which is considered an indicator o

location, The type of fish samples has been revised to identify fish as either predator or o

scavenger fish, A control sample iocation for invertebrates was established, o

3.

Game The requirement for the collection of game has been deleted, based upon historical o

nuclide identifications and the fact that the land use census data does not Indicate I'

these sample types as being a significant source of food for human consumption.

The number o' aesturage sampling indicator locations has been reduced fium 8 to o

been eliminated were not located in areas where milk animals graze.

The number of garden sites has been reduced from 11 to 3 sampling locations.

deposition pathway The indicator location for this pathway that is retained is the j

garden near the site boundary in the second highest average calculated D/O value.

The methods for establishing error estimates included review of applicable station procedures, inspection of sampling equipment, engineering estimates, statistical applications, review of calibration setpoint data, and communication with plant personnel. The various sources of error (a) in reported values of gaseous effluents, liquid effluents, and solid waste are assumed to be independent, and thus the total error is calculated according to the formula:

Totel Error = d of + oj + oj... + ci where: og = relative error associated with component i Sources or error for gaseous effluents include WGDT pressure, fan error (flow), grab sampling, collection, filter efficiency, counting, and calibration.

Sources of error for liquid effluents include RHUT volume, dilution water flow rate, grab sampling, counting, and calibration.

I Sources of error for solid waste include offsite lab smear analysis, dose rate meter calibration, L

dose rate meter reading, Wastetrak dose-to-curie calculation, sample volume measurement, gamma spectroscopy counting, gamma spectroscopy calibration, and waste volume determination.

RSN3S sEM6 ANNUAL RADioACTNE EFFLUENT RELEASE REPORT I

JANUARY JUNE 1990 yll METEOROLOQlCAL DATA l

The meteorological data for Rancho Seco Nuclear Generating Station for Quarter 1 and Quarter 2 of 1990 is presented in this section. A joint frequency distribution (JFD) table indicates the number of hours in a quarter at each combination of wind speed and direction for a given i ag atmospheric stability class. Included are JFD tables for each separate stability class as well as a composite to summarize all classes.

i The data is dNided further to account for the mode of release. Continuous release data takes Into account all hourly averages in the entire quarter. Batch release meteorology is not included since no batch releases of gaseous radioactNo effluents have occurred in 1990.

The following meteorological data was determined in accordance with USNRC Regulatory Guide 1.111, Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light Water Cooled Reactors. Meteorological information from 'he site I

meteorological tower was used to complete the data for the JFDs. The meteorolo; J data acquisitions system recovered 94.4% of the data for Quarter 1 and 97.9% of the da for Quarter 1

2 of 1990. Measurements from the meteorological tower have been made in accordance with USNRC Regulatory Guide 1.23, Onsite Meteorological Programs.
