I SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION EXECUTIVE

SUMMARY

The Rancho Seco Nuclear Generating Station Unit No. I is located approximately 26 miles north-northeast from Stockton and 25 miles southeast from Sacramento in Sacramento County, California. Rancho Seco Unit No. I began commercial operation on April 17, 1975. The single unit on the Rancho Seco site is a pressurized water reactor supplied by Babcock & Wilcox.

The rated capacity is I

2,772 megawatts thermal and 963 gross megawatts electrical.

This report has been prepared by the Sacramento Municipal Utility District to meet the reporting requirements of Technical Specification 6.9.2.3, Operating License No. OPR-54.

It is transmitted to the U. S. Nuclear Regulatory Commission Region V Office of Inspection and Enforcement. Copies are provided to the California Energy Commission, California Department of Public Health, California State University at Sacramento, Central Valley Regional Water Quality Control Board, local libraries, and District offices as a public document.

This document reports the quantities of radioactive materials released as liquid and gaseous effluents, and solid radwaste shipments.

Estimates of the I

radiological impact to man associated with the gaseous and liquid effluent releases are presented.

The report period is January 1, 1986 through June 30, 1986.

The format of this report follows U. S. NRC Regulatory Guide 1.21 as required by Technical Specification 6.9.2.3.

There are six major sections:

(1)

Gaseous Effluents; (2) Liquid Effluents; (3) Solid and Radwaste shipments; (4)

Radiological Impact on Man; (5) Meteorological data; and (6) Supplemental Information. Each section contains, where appropriate, narrative or descriptive material to clarify the tables.

In accordance with Technical Specifications, the District maintains an Offsite Dose Calculation Manual.

It contains the detailed methods and procedures to perform the radiological impact calculations supporting this report.

Technical Specification 6.9.2.3 requires this report to include changes to the Offsite Dose Calculation Manual (ODCM) and the solid radwaste Process Control Program (PCP), assessments of radiation doses associated with radioactive effluents to unrestricted areas, and reports of abnormal releases.

There were no substantive changes to the ODCM or PCP and no abnormal releases to report in this report period.

'I The Rancho Seco Technical Specifications now implement the numerical guidelines for design objectives of 10 CFR 50, Appendix I.

If the discharge of radioactive effluents results in a calculated radiological dose to a composite hypothetical maximum individual less than the numerical guidelines, then the facility has demonstrated that it is being operated ALARA.

The ALARA concept is to keep the radiological exposure to individuals or the general I

public As Low As Reasonably Achievable.

1

SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION The numerical guidelines for gaseous effluents are:

(1) 10 mrad gamma air dose per calendar year (2) 20 mrad beta air dose per calendar year (3) 5 mrem to the total body per calendar year (4) 15 mrem to any organ per calendar year The numerical guidelines for liquid effluents are:

(1) 3 mrem to the total body per calendar year (2) 10 mrem to any organ per calendar year These numerical guidelines are not to be interpreted as radiation protection standards and the calculated dose, although presented in units of mrem, is not considered a real radiological dose to a real individual. The calculational methodology used by the license to convert effluent (curies) into radiation dose (mrem) is required by Technical Specifications to be documented in the Licensees' Offsite Oose Calculation Manual (00CM).

The ODCM follows NRC guidance documents and NRC calculational models.

The 10 CFR 50, Appendix I effluent dose calculations provide management with a forecast of potential future environmental conditions given that the existing facility equipment and procedures con,tinue to allow the current effluent levels.

The Radiological Environmental Monitoring Program (REMP) is designed to monitor the actual radiological environmental conditions surrounding the facility.

Results of the REMP are reported in the Annual Radiological Environmental Operating Report.

The 00CM, REMP, and the Annual Land Use Census are matrixed in a very dynamic process to provide District management, the NRC, and the general public reasonable assurance that the Rancho Seco radioactive effluents are ALARA. A revision to the 00CM is scheduled to occur later in 1986.

Exceeding one-half of a numerical guideline in any calendar quarter requires the licensee to (1) make an investigation to identify the causes for the g

effluent releases, (2) define and initiate a program of corrective actions, g

and (3) submit a report to the NRC regional office within 30 days from the end of the quarter during which the release occurred.

l Exceeding a numerical guideline in any calendar quarter requires the licensee to do all of the above plus an evaluation of compliance with the EPA standards.

The Environmental Protection Agency (EPA) has implemented Environmental Radiation Protection Standards for Nuclear Power Operations (40 CFR 190) which the NRC enforces through 10 CFR 20.106.

These standards are 25 mrem to the whale body and any organ except for the thyroid which has a limit of 75 mrem.

These standards relate to a real radiological exposure to a real individual, combine the exposures due to liquid, gaseous, and direct pathways, and cover a twelve month interval rather than a calendar year.

11 I

I SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SEC NUCLEAR GENERATING STATION If the standards of 40 CFR 190 are exceeded, the licensee must prepare and I

submit a report within 30 days to the NRC that includes (1) the extent of exposure of individuals to radiation or to radioactive material, (2) levels of radiation and concentrations of radicactive material involved, (3) the cause of the exposure, levels, or concerdrations, and (4) corrective steps taken or planned to assure against recurrence, including a schedule for achieving conformance with 40 CFR 190 and with associated license conditions.

The NRC can grant the licensee a variance to 40 CFR 190 under certain conditions.

The NRC radiation protection standard for members of the general public is 500 mrem per calendar year. Concentrations of radioactive effluents are limited to the values in 10 CFR 20, Appendix B, Table II which are values which can be equated to a 500 mrem per year dose.

The NRC can limit the radioactive effluent concentraticns to one-third these values if the need arises.

Rancho Seco was originally designed to meet the criteria of 10 CFR 20.

The ALARA concept for radioactive effluents was not established in 10 CFR 50 until after Rancho Seco began commercial operation.

The numerical guidelines of 10 CFR 50, Appendix I were incorporated into the Rancho Seco Technical Specifications July, 1984.

I Early in 1984, district staff discovered that the liquid effluent dose calculations were not being performed in accordance with the NRC calculational methodology and the Rancho Seco Offsite Dose Calculation Manual (00CM). After correcting the calculations, the District reported a calculated dose via liquid effluents to a maximum hypotheti gi individual of 186 mrem to an adult total body and 305 mrem to a child liver'for calendar year 1984.

The District initiated a liquid effluent control program in October 1984 which has significantly reduced the quantity of radioactivity in liquid effluent.

As an example, the Olstrict has reported discharging 0.3 curies of cesium-137 in 1984, 0.004 curles of cesium-137 in 1985, and only 0.0007 curies of cesium-137 in the first six months of 1986.

Once the calculational errors were discovered, the District initiated an I

extensive environmental monitoring program using the Lawrence Livermore National Laboratory, conducted an extensive liquid effluent pathway land use census, tronitored individuals in the general public for radiation, and submitted numerous reports to the NRC as required by both 10 CFR 50, Appendix I and 40 CFR 190.

In June 1986, the NRC concluded that "since it has not been reasonably I

established that a real member of the public received a dose in excess of the 40 CFR 190 standard, no violation of 10 CFR 20.106(g) has been identified."

A NRC inspection in April, 1986 caused the Olstrict to reevaluate the 1985 radioactive liquid effluent discharge. A special report (Special Report No. 86-08 June 5, 1986) was submitted to the NRC with the results of this reevaluation. As required by Technical Specification 6.9.2.3, this report I

includes the revisions to the two 1985 Semiannual Radioactive Effluent Release til I

SEMTANNUAL RADf0 ACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION Reports resulting from the above reevaluation. The Olstrict is now reporting 3

a calculated dose resulting from radioactive liquid effluents to a maximum 3

hypothetical Individual of 4.8 mrem to an adult total body and 16.2 mrem to a child liver for calendar year 1985.

Because of the April, 1986 NRC inspection and the reevaluation of the 1985 liquid effluents, the Olstrict is significantly expanding the radioactive liquid effluent control program.

The radioactive effluent discharged from Rancho Seco during the first and second quarters of 1986 equates to a calculated dose of:

First Quarter Second Quarter Liquid effluent total body (mrem) 0.99 0.018 E

organ (mrem) 1.85 0.054 5

Gaseous effluent organ (mrem) 0.13 0.018 gamma air (mrad) 0.029 0.000001 beta air (mrad) 0.087 0.00013 I

All of the above values are below the numerical guidelines of 10 CFR 50, Appendix I, and no 40 CFR 190 evaluation is required.

==

Conclusion:==

The radioactive effluents discharged from Rancho Seco frcm January 1, 1986, through June 30, 1986, are ALARA.

SUPPLEMENTAL INFORMATION Supplemental information as outlined in Regulatory Guide 1.21 is presented in this section of the report.

A.

GASECUS EFFLUENTS Gaseous effluents are assumed to be ground level release and are summarized in Table II-A," Gaseous Effluents - Summation of All Releases," and Table II-8, " Gaseous Effluents - Ground Level Releases." Elevated releases are not evaluated or reported at Rancho Seco because the gaseous effluent stack height is less than the height of its adjacent structure.

There were 8 Waste Gas Decay Tank releases and 11 Reactor Building purges during the period January 1 through June 30, 1986.

There were no abnormal release of radioactive gases in this report period.

B.

LIQUID EFFLUENTS There were 93 batch releases from Regenerant Holdup Tanks (RHUT) with the material ultimately released by 41 Retention Basin discharges.

Liquid releases are summarized in Table III-A and the isotopic contents are detailed in Table III-B. There were no abnormal releases of radioactive liquid in this report period.

I The estimate of the quantity of radioactivity in liquid effluent was determined in the following manner. Samples are routinely collected from each of the RHUT discharges and composited for analysis on a monthly basis.

These monthly composites are then sent to the Olstrict's environmental monitoring contractor for strontium and alpha analysis.

The District requests that these samples also be analysed for gamma emitting radionuclides to better estimate the radioactive 11guld effluent release. Beginning in November 1985, the RHUT samples were separated into radiological and nonradiological samples and composited separately on a monthly basis.

If the RHUT sample analysis resulted in observable tritium or gross beta, the sample was added to the radiological composite and its discharge volume added to the radiological liquid effluent volume.

If no tritium, gross beta, or gamma emitting nuclides were observed, the I

sample was added to the nonradiological composite and its volume added to the nonradiological liquid effluent volume.

If the monthly composite sample analysis results in a higher estimate of radioactive liquid effluent than the individual RHUT sample analysis performed onsite, the higher values are recorded and reported.

I I

SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION I.

SUPPLEMENTAL INFORMATION The quantities of radioactive liquid effluent in Table III-A and Table III-B are the results of both onsite sample analysis and analysis of the monthly RHUT composites by the District's environmental monitoring contractor.

The Olstrict's environmental monitoring contractor's LLDs are much lower than the values reported in Table III-C which are typical of the District's on site LLO capabilities.

C.

SOLIO WASTE There were 12 shipments of radioactive wastes to the Hanford Burial Site between January 1 and June 30, 1986.

These consisted of l

200 ft3 containers of solidified 11guld waste, primary and low 3

activity secondary resins, and cartridge type filters incorporated into concrete under an approved Process Control Program and shipped in approved LSA containers.

In addition, dry compressible waste and contaminated equipment was shipped in approved LSA containers.

D.

MAXIMUM PERMISSIBLE CONCENTRATIONS The maximum permissible concentrations (MPC) used to calculate the percent of Technical Specification Limits in Tables II-A and III-A were obtained from 10 CFR 20, Appendix 8, Table II.

E.

OFFSITE DOSE CALCULATION MANUAL (00CM) CHANGES The September 23, 1985 revision to the ODCM was submitted to the NRC with the January-June 1985 Semiannual Radioactive Effluent Release Report on September 26, 1985 with the intent of providing the NRC with the revisions in an expeditious manner. The Olstrict went beyond the requirements of Technical Specification 6.9.2.3 by submitting this revision prior to the required date, which would have been with the transmittal of the July-December 1985 Semiannual Radioactive Effluent Release Report.

The calculational methodology of an ODCM is modeled after the US NRC Regulatory Guide 1.109, " Calculation of Annual Doses to Man from a

Routine Releases of Reactor Effluents For the Purpose of Evaluating B

Compilance with 10 CFR Part 50, Appendix I," October 1977.

This regulatory guide describes basic features of the calculational models and suggests parameters for the estimation of radiation doses to man from effluent releases.

The licensee is encouraged to use site-specific values but the assumptions and methods used to obtain these parameters should be fully described and documented. I

SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GEi ERATING STATION I.

SUPPLEMENTAL INFORMATION The current Rancho Seco 00CM uses the calculational methodology described in Regulatory Guide 1.109 and implements it for the liquid effluent pathway by using the LADTAPII computer code described in NUREG/CR-1276, " User's Manual for LADTAPII, A Comouter Program for Calculating Radiation Exposure to Man From Routine Releases of Nuclear Reactor Liquid Effluents," May 1980.

Specific site related parameters which are used in the Rancho Seco 00CM, other than those suggested in Regulatory Guide 1.109, are documented in the following reports:

1.

Final Environmental Statement related to the operation of Rancho Seco Nuclear Generating Station Unit 1, March 1973, US AEC.

2.

5.

User's Manual for LADTAPII, A Computer. Program for Calculating Radiation Exposure to Man From Routine Release of Nuclear Reactor Liquid Effluents, May 1980, NUREG/CR-1276.

The drinking water pathway is not included in the liquid effluent pathway due to the information in the Final Environmental Statement and confirmed by the Usage Survey Report.

Boating and irrigated leafy vegetables are not included due to information in the Usage Survey Report.

The parameters YIELO and GROW were added to the I

LADTAPII ccde as input parameters to accommodate information provided in the Appendix I Evaluation Report. An irrigaticn rate of 263 liters / meter 2 month is used in the irrigated foods pathway which

/

also comes from the Appendix I Evaluation Report. Reduced freshwater invertebrate consumption values and increased freshwater fish consumption values are used due to the Usage Survey Report.

The bloaccumulation factor for cesium in freshwater fish was reduced from 2000 to 1400 due to information in UCID-20367.

It is important to realize that it is the product of the consumption value and the i

bloaccumulation factor that enter into the resultant dose and that j

the current Rancho Seco 00CM would calculate a higher dose tnan if the suggested values of Regulatory Guide 1.109 were used. Some additional minor changes to the LA0TAPII code were made in the F000 and WATER subroutines as a result of personal communications between I

Mike Wangler, NRC Washington, and E. W. Sradley of the District.

Dairy cattle are also assumed not to be drinking water directly from the effluent stream.

ESTIMATION OF ERROR I

The estimate of error is based on combination of the following error estimates:

A.

Airborne 1.

counting error 2.

calibration error of exhaust fans 3.

sample train flow rate meter error 4.

process monitor flow rate setpoint error 5.

charcoal cartridge efficiency 6.

tritium bubbler collection efficiency I

7.

loss due to handling (for particulates) 8.

Haste Gas Decay Tank (WGDT) pressure gauge and flow rate meter errcrs B.

Liquid 1.

counting error i

2.

Regenerant Hold Up Tank (RHUT) release volume error 3.

retention basin dilution error 4.

retention basin outlet flow error 5.

flow rate error of discharge canal The following error estimates were considered, found to be negligible, and therefore were net considered in the error analysis:

1.

Marineill flask volume 2.

sample mixing 3.

particulate filter loss 4.

loss due to handling for lodine 5.

composite aliquots for 11gulds I

Error estimates for anisokinetic sampling and airborne particulate plateout in monitor sample lines were not included because no plant data exist cn the subject. However, this does not necessarily mean the errors are negligible.

The methods for establishing error estimates included communication with Olstrict health physics / chemistry personnel, review of applicable station I

procedures, inspection of sampling equipment, review of previous District error analysis data, engineering estimates, statistical applications, literature reviews, and use of calibration set points data.

In determining the overall error in a release, error at one standard deviation and a bias were calculated.

The error consists of random or indeterminate errors.

Blas is influenced primarily by determinate errors I

which introduce a constant error into the data. I

I SEMIANNUAL RA010ACTZUE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION V.

Liquid Releases Includes the total error analysis for the RHUT to retention basin to discharge canal flow path.

It should be noted that the error analysis for todines and particulates that are released through the reactor building vent includes exhaust fan calibration error, not containment volume error. This is because iodines and particulates are vented on a continuous basis by the exhaust fan via a pre-filter, HEPA filter and charcoal cartridge. Also, error analysis for fission and activation gases and tritium that are released through the g

reactor building vent includes containment volume error, not exhaust fan g

calibration error.

This is because fission and activation gases and tritium are released is a function of containment volume.

Note:

Includes releases from the condenser air ejector, gland seal exhaust, and lodines and particulates from the NGOT.

The Radwaste Service Area Vent was not included as a release pathway due to Its inoperabi1ity.

Tne error for both airborne and 11guld releases was determined at one standard deviation from the mean. I

SEMIANNUAL RADECACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1986 RANCHO SECO NUCLEAR GENERATING STATION VII. METEOROLOGICAL DATA Meteorology The meteorology of the Rancho Seco Nuclear Generating Station for the first and second quarter, 1986 is described in this section.

Meteorological measurements have been made according to the guidance set forth in U.S. NRC Regulatory Guide 1.23, "Onsite Meteorological E

Programs." A summary report of the meteorological measurements taken E

during each calendar quarter are presented in Tables VII-B through VII-E as a joint frequency distribution of wind direction (frcm), wind speed, and atmospheric stability class.

Hourly meteorological data for continuous and batch releases have been recorded.

This data is available but has not been included in this report because of the bulk of data records.

The meteorological data acquisition system for Rancho Seco consists of a permanent meteorological tower installed at the site, instrumentation and on-line computer. The main purpose of the system is to measure and compile the meteorological data necessary to define the atmospheric diffusion and dispersion at the site.

The system is designed to continue in operation indefinitely so that a broad statistical base for meteorological conditions at the site can be assembled.

The 200-foot meteorological tower is located on a hill approximately 3,000 feet east of the Reactor Building.

The location is unobstructed by trees. buildings or topographical features. A Rohn SSV tower, of open lattice construction, is used to support the instrumentation.

The tower has sufficient rigidity so that measurement errors are not introduced by tower vibrations. Also, the open lattice design of the tower does not significantly obstruct the air flow near the tower.

The tower was reinstrumented in late 1981 and now consists of:

Wind speed measurements - 4 Heather Measure H203 anemometers with SS cups and HF tachometer generator (2 sensors at the 60 meter level and 2 sensors at the 10 meter level).
