SUMMARY

The Rancho Seco Nuclear Generating Station Unit No.1 is located approximately 26 miles north-northeast from Stockton and 25 miles southeast from Sacramento in Sacramento County, California. Rancho Seco Unit No. 1 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 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, gaseous effluents and solid radwaste shipments. Estimates of the radiological impact to man associated with the gaseous and liquid effluent releases are presented. The report period is July 1, 1985 through December 31, 1985.

(U / 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. Several items included in Regulatory Guide 1.21 have been retained in this report, although they are outmoded by the " dose-based" Technical Specifications.

Additional information required by Technical Specification 6.9.2.3 is also presented. This includes changes to the Offsite Dose Calculation Manual and the solid radwaste Process Control Program, assessments of radiation doses associated with radioactive effluents to unrestricted areas, and reports of abnormal releases.

In accordance with Technical Specifications, the District maintains an Offsite Dose Calculation Manual. It contains the detailed methods and procedures to perform the calculations supporting this report.

The radiological liquid ef fluent control program that began in October 1984 has continued during this report period. Normal liquid effluent releases of radionuclides other than tritium continue to be below the limits of detection required by Technical Specifications 4.21.

The estimates of radiation doses equivalent to the non-occupational maximally

\ exposed individuals are one or more orders of magnitude smaller than the

[m) limits of 10 CFR Part 50, Appendix I.

SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JULY-DECEM8ER 1985 RANCHO SECO NUCLEAR GENERATING STATION I. SUPPLEMENTAL INFORMATION - EFFLUENT AND WASTE O!SPOSAL REPORT A. SUPPLEMENTAL INFORMATION Supplemental information as outlined in Regulatory Guide 1.21 is presented in this section of the report.

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

There were 5 Waste Gas Decay Tank releases and 7 Reactor Building purges during the period July 1 through December 31, 1985. There was one abnormal release of radioactive gases in this report period.

C. LIQUID EFFLUENTS Residual gamma emitters from the secondary system have not been detected in the waste water stream during this report period.

There were 113 batch releases from Regenerant Holdup Tanks with the

material ultimately released by 48 Retention Basin discharges.

Liquid releases are summarized in Table I!!-A and the isotopic contents are detailed in Table III-B. There were two abnormal liquid releases in this report period.

D. SOLID WASTE There were 77 shipments of radioactive wastes to the Hanford Burial Site between July 1 and December 31, 1985. These consisted of 200 ft3 containers of solidified liquid waste, primary and low 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.

July-December A. GASEQUS The only gaseous abnormal release was associated with a reactor transient on December 26, 1985. Radioactivity was released via primary-to-secondary leakage hence to atmosphere from secondary s.sfety relief and dump valves. 3 The quantity of radioactive material released totalled 32.7 curies of noble gases. The maximum doses to a hypothetical individual at the "

exclusion area boundary were 0.06 mrem to the total body and 0.2 mrem to

the skin.

Corrective action is associated with the larger investigation into the

transient.

B. LIQUID

1. While aligning valving and equipment to fill "A" stean generator on July 24, 1985, secondary water was unintentionally allowed to drain from a hose connected to the system to the storm drains. Analysis of ,

the secondary system water indicated concentrations of Cs-134 at 3.64 nC1 per liter and Cs-137 at 7.74 nCt per liter. A volume estimated i at 450 liters was released into the plant effluent stream during a period of about two hours. Historical effluent flow rate during this j period averaged 11,400 liters per minute.

. The resulting calculated concentrations in the effluent and maximum j organ doses are as follows:

2. Approximately 30 gallons of tritiated water were released to the

< ground on December 28, 1985 as a result of draining the PASS backup j water cooling tank. The concentration of tritium was 17 microcuries i

) per liter for a total release of 1930 microcuries. No radiological concequences are expected due to diffusion and evaporation.

RANCHO SECO NUCLEAR GENERATING STATION V. ESTIMATION OF ERROR An estimate of the errors associated with determining the airborne and liquid radioactive releases was made for Rancho Seco Unit No. 1. The airborne releases include continuous releases and decay tank releases from the Auxiliary Building Stack, Reactor Building purges, and Gland Seal Exhaust. The liquids consist of solidified Radwaste shipments and controlled liquid discharges from the plant.

Considerations used in estimating the errors of the airborne releases in-lude the following items: (1) anisokinetic sampling, (2) deposition of sample in lines, (3) losses through particulate filters, (4) inefficiencies of the charcoal cartridge, (5) losses due to handling, (6) flow rate uncertainties, (7) decay tank pressure changes, and (8) counting statistics. Items included in the liquid release error analysis were: (1) sampling, (2) volume measurements, and (3) counting statistics.

A compilation of the error analysis is given in the subsequent sununary.

The compilation presents both the positive and negative error values.

For the purpose of this report, rather than present a detailed statistical evaluation of both error values, the higher (negative) values are assigned. All errors are calculated at percent values.

1 SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JULY-DECEMBER 1985 RANCHO SECO NUCLEAR GENERATING STATION TABLE VI-C THERM 0 LUMINESCENT 00SIMETRY MONITORING RESULTS Introduction The District uses a Matsushita model U0-7020 TLD system. Two model 804 dosimeters are placed at each monitored location. Each dosimeter contains three CaSO 4 :tm phosphor. Each phosphor is considered a discrete data point. Therefore, six data are available at each monitored location.

Third quarter dosimeters were placed during the period June 12-14,1985 and retrieved during the period September 10-13, 1985. Fourth quarter dosimeters were placed during the period September 10-13, 1985 and retrieved during the period December 19-24, 1985.

An average hourly exposure rate is presented in addition to the quarterly total exposure for each location. The hourly exposure rate is derived by dividing the total exposure by the actual exposure period for each location.

Dosimeters which were missing from the monitored location at the time of retrieval are so noted in the table.

The exposure values for locations 3 and 4 reflect the storage of radioactive waste nearby. The high exposures associated with location 52 are likely to be due to the granite structure of the Jackson Civic Center building. Location 41 has a history of higher-than-average exposure values which are not substantiated by nearby dosimeters or by calculation from releases. No specific source for the deviation has yet been located.

SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JULY-DECEMBER 1985 RANCHO SECO NUCLEAR GENERATING STATION VII. METEOROLOGICAL DATA Meteorology The meteorology of the Rancho Seco Nuclear Generating Station for the third and fourth quarter,1985 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 Programs." A summary report of the meteorological measurements taken during each calendar quarter are presented in Table 4A as a joint frequency distribution (JFD) of wind direction, 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 systera 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 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 Weather Measure W203 anemometers with SS cups and HF tachometer generator (2 sensors at the 60 meter level and 2 sensors at the 10 meter level).

Starting threshold <1 mph Range 0 to 100 mph Accuracy al percent or .15 mph whichever is greater 9

SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JULY-DECEMBER 1985 RANCHO SECO NUCLEAR GENERATING STATION Wind direction measurements - 4 Weather Measure W204 light-weight vanes. (2 sensors at the 60 meter level and 2 sensors at the 10 meter level).

Threshold <1 mph Damping ratio .4 Distance constant 1.9 ft 4

Range O to 540*

Accuracy 0.5 percent or al.8*

Temperature measurements - 4 Weather Measure TP-100 platinum probe Model IS6 motor aspirated shield (temperatures at 60 meter and 10 meter levels).

Range -40 to 120*F Accuracy 40.l*F l -

l Dew point - 2 Mfgr Standard YSI-9400 with aspirator shield at the 10 meter i level.

Range -40 to 120*F Accuracy a2.0*F Ouring the first quarter 1985, the meteorological data acquisition system recovered 95.7% of the data. During the second quarter, 95.4% of the data was

! recovered.

The District's contract meteorologist is in the process of reviewing the 1985 meteorological data and has expressed some preliminary concerns about the delta temperature data that is used to determine the atmospheric stability class. The District will keep the NRC informed of progress in this evaluation. If the evaluation results is a significant change to the joint frequency distribution, the District will recalculate the gaseous effluent pathway dose and submit an amendment to this report.
