V EXECUTIVE

SUMMARY

i The Rancho Seco Nuclear Generating Station Unit No. 1 is located approximately 26 miles north-northeast from Stockton and 25 miles southeast l

from Sacramento in Sacramento County, California.

Rancho Seco Unit No. 1 began commercial operation on April 17, 1975.

The single unit on the Rancho I

I 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 Munic w i Utility District to meet the reporting requirerents of Technical Specification 6.9.2.3.

l Operating License No. DPR-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, Sacramento County Health Officer, and District offices as a public document.

This document reports the types and quantities of radioactive materials discharged in liquid and gaseous effluents, and solid radwaste shipments.

Estimates of the radiological impact to man associated with the gaseous and liquid effluent discharges are presentd.

The report period is July 1, 1987 through December 31, 1987.

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

There are six major sections: (1)

Gaseous Effluents: (2) Liquid Effluents: (3) Solid Haste shipments: (4)

Radiological Impact on Man; (5) Meteorological data; and (6) Supplemental Information.

Each section contains, where appropriate, narrative or i

l descriptive material to clarify the tables.

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

It contains the detailed methods and I

procedures to perform che radiological impact calculations supporting this report.

l 1

Technical Specification 6.9.2.3 requires this report to include changes to l

the Offsite Dose Calculation Manual (ODCM) and the solid radwaste Process j

Control Program (PCP), assessments of radiation doses associated with radioactive effluents to unrestricted areas, reports of abnormal releases, I

and instances where radioactive effluent mcnitoring instrumentation is l

inoperable for periods greater +.han 30 days.

There were three abnormal liquid releases during this report period.

i lO

SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1987 RANCHO SECO NUCLEAR GENERATING STATION EXECUTIVE SUM M A revision to the Offsite Dose Calculation Manual was implemented on December 9, 1987.

The interim change to the Offsite Dose Calculation Manual was made to correct technical errors and provide for equipment changes at Rancho Seco Nuclear Power Station, The 00CM changes are described in Appendix E.

The Process Control Manual (PCP) was completely reformatted and approved by the Plant Review Committee on December 1, 1987.

Details of the changes to the PCP are in Section IX of this report. Appendix G is a copy of the new PCP.

The Appendix I numerical guidelines for gaseous effluents are:

(1) 10 mrad gamma air dose per calendar year /5 mrad per calendar quarter (2) 20 mrad beta air dose per calendar year /20 mrad per calendar quarter (3) 15 mrem to any organ per calendar year /7-1/2 mrem per calendar quarter The Appendix I numerical guidelines for liquid effluents are:

(1) 3 mrem total body per calendar year /1-1/2 m,7m per calendar quarter (2;

10 mrem total body per calendar year /5 mrem per calendar quarter O

The redioective effiuent dischar9ed from Rencho Seco durin918 third and fourth quarters of 1987 equates to a calculated dose of:

RANCHO SECO NUCLEAR GENERATING STATION s

Part 190 of Title 40, Code of Federal Regulations, (40 CFR 190) requires that dose to any member of the public from Rancho Seco Nuclear Operations be less than 25 mrem to the total body or 75 mrem to the thyroid.

If the dose to a maximum hypothetical' individual is twice the annual limits of Appendix I, 10 CFR 50, then dose calculations must be performed to determine compliance with limits of 40 CFR 190.

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

==

Conclusion:==

The radioactive effluents discharged from P.ancho Seco from July 1, 1987, through December 31, 1987, resulted in dosages that were as low as reasonably achievable.

RANCHO SEC0 NUCLEAR GENERATING STATION I.

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

A.

GASEOUS EFFLUENTS All releases of gaseous effluents occurred at the ground level.

They are summarized in Table II-A, "Gaseous Effluents - Summation of All Releases," and Table II-8, "Gaseous Efficents - Ground Level Releases."

Elevated releases were not evaluated because the gaseous effluent stack height is less than twice the height of its adjacent structure.

There were 6 Haste Gas Decay Tank releases and 25 Reactor Building batch releases during the period July 1 through December 31, 1987.

There were no abnormal gaseous releases of radioactive material in this report period.

B.

LIQUID EFFLUENTS There were 17 batch releases of radioactive liquid from the Regenerant Holdup Tanks (RHUT).

The water was ultimately released p

by 34 Retention Basin discharges.

Liquid releases are summarized d

in Table III-A and the isotopic contents are detailed in Table III-0.

There were three abnormal releases of radioactive liquid in this report period.

C.

SOLID HASTE There were 6 shipments of solid radioactive wastes to the Hanford Burial Site between July and December 31, 1987.

These consisted of Low Specific Activity (LSA) boxes and 55 gallon drums.

D.

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

The most conservative HPC valves were selected for use in the calculations.

ABNORMAL RELEASES Abnormal releases are defined as an unplanned or uncontrolled release of radioactive material from the site boundary.

A.

GASEOUS There were no abnormal Gaseous releases during the report period.

B.

LIOUID 1.

On Tuesday, September 1, 1987 valve FHS-020 leaked approximately 2,490 gallons of water to a storm drain which led offsite.

The water that is normally in this drain does not contain radioactive material.

The measured concentration of the water was 5.31 E-7 pC1/ml of Cesium 137 and 1.08 E-7 pCi/ml of Cesium 134.

The total amount of radioactive material released offsite was 6.03 E-6 Curies.

Calculations were performed in accordance with the ODCH using the above information.

The results indicated a calculated whole body dose to a maximum hypothetical adult individual of 3.32 E-3 mrem and an organ dose of 4.74 E-3 mrem.

O 2.

On August 28, 1987 approximately 2000 gallons of liquid leaked from the steam line atmospheric dump valves (ADVs) to a drain below the valves.

The drain led directly offsite.

The water that is normally in this drain does not contain radioactive material.

The measured concentration of the water that was released was 5.14 E-8 pCi/ml Cesium 137.

The total amount of radioactive material released was 3.89 E-7 Curies.

Calculations were performed in accordance with the ODCH using the above information.

The results indicated a calculated whole body dose to a maximum hypothetical adult individual of 1.94 E-4 mrem and an organ dose of 2.91 E-4 mrem..

SUPPLEMENTAL INFORMATION ABNORMAL RELEASES (Continued) 3.

On November 15, 1987 approximately 5 gallons of water overflowed from the "B" Steam generator level indicator to a storm drain on the 40 foot level of the Auxiliary Building.

The storm drain led directly offsite.

The water that is normally in this drain does not contain radioactive material. The measured concentration of the water that was released was 1.00 E-7 pCi/ml of Cesium 137.

The total amount of radioactive material released was 1.89 E-9 Curies.

Calculations were performed in accordance with the OOCH using the above information.

The results indicated a calculated whole %dy dose to a maximum hypothetical adult individual of 9.46 E-7 mrem and an organ dose of 1.42 E-6 mrem.

4.

Actions to Frevent Recurrence of Abnormal Releases The Short Term Effluent Control Task Force was established in late November, 1987, by the CEO-Nuclear.

The purpose of this task force was to identify and implement immediate, short and long term actions that would minimize the potential for an unmonitored j

release of either PCBs (Polychlorinated biphenyls) or radioactive O

effluent.

High risk drains have been identified.

Immediate corrective actions implemented thus far include, but are not limited to, floor drain plugging, diversion dikes, and various administrative controls to reduce the risk for leaks or spills.

Both short term and long term corrective actions have been proposed as appropriate.

Engineering evaluations, cost-benefit analysis, capital appropriations, work requests, etc., are being accomplished on a case-by-case basis to implement the recommendations. A complementary effort is also underway to systematically eliminate identified sources of leaks or spills that have significant i

potential for causing an unmonitored release. All recommendations are being coordinated with the Radiological Effluent Control Program and Hazardous Materials Task Force to ensure that the short term solutions will meet the long term goals of these two programs.

UNHONITORED RELEASES During this report period, there were two instances in which an unmonitored release of gaseous material were made from discharge vents that are used for radioactive gaseous materials. Analysis showed that no radioactive material was released off site.

SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1987 RANCHO SECO NUCLEAR GENERATING STATION I.

SUPPLEMENTAL INFORMATION (Continued) 1.

On September 23, 1987 Engineers and Technicians started to perform testing of the Auxiliary Building Grade Level Vent System.

Because of a design error, the fan motor for the Vent System started.

This resulted in an unmonitored release of gaseous material from Rancho Seco Site.

Subsequent analysis of air samples from the areas serviced by the Auxiliary Building Grade Level Vent System and other analysis showed

~

that no radioactive material was released during this event. The design fault was corrected.

Procedures involving the use of the system were also improved to prevent a recurrence of an unmonitored release from Auxiliary Building Grade Level Vent System. This event is detailed in Licensee Event Report 87-043.

2.

On November 16, 1987, the first seven minutes of a 6,930 minute purge of the reactor building was not monitored.

The remainder of the discharge was monitored in accordance with Rancho Seco Procedures. Analysis of pre-release samples, purge samples and post-release samples showed that no radioactive material was released.

This event occurred due to a personnel error. The appropriate procedures were modified in order correct the problem.

This event is detailed in Licensee Event Report 87-047.

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.

Counting error 2.

Regenerant Hd d Up Tank (RHUT) release volume error 3.

Retention basin dilution flow error 4.

Retention basin outlet flow error The following error estimates were considered, found to be negligible, and therefore were not considered in the error analysis:

1.

Marinelli flask volume 2.

Sample mixing 3.

Particulate filter loss 4.

Loss due to handling for iodine 5.

Composit'e aliquots for liquids Error estimates for isokinetic sampling and airborne particulate plateout in monitor sample lines were not included bec&use no plant data exist on the subject.

However, this does not necessarily mean that the errors are negligible.

The methods for establishing error estimates included communication with District health physics / chemistry personnel, review of applicable station procedures, inspection of sampling equipment, review of previous District error analysis data, engineering estimates, statistical applications, literature reviews, and use 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.

Bias is influenced primarily by deterministic error which introduce a constant error into the data, y

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 iodines 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 and charcoal filter.

Also, error analysis for fission and activation. gases and tritium that are released through the reactor building vent includes containment volume error, not exhaust fan calibration error.

This is because fission and activation gases and tritium are released as a j

function of containment volume.

ILqta:

Includes releases from the condenser air ejector, gland seal exhaust, and iodines and particulates from the HGDT.

The Auxilary Building Grade Level Vent was not included as a release pathway due to its inoperability.

The error for both airborne and liquid releases was determined at one standard deviation from the mean.

SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1987 RANCHO SECO NUCLEAR GENERATING STATION HQII:

The 12/23 to 12/26 Particulate sample from the Reactor Building Vent for Strontium 90 and Strontium 89 was misplaced after the sample was analyzed for gamma emitting activity. A detailed report of this occurrence is documented in Occurrence Description Report 87-1053.

The technician who discovered the misplaced sample found two samples in the envelope for the Auxiliary Building Vent sample.

The vent air samples are identical filter papers which are not visibly different.

Because no gamma emitting radioactivity was detectr e on the samples, it was not possible to distinguish the Reactor Building Vent sample from the Auxiliary Building Vent sample.

The Reactor Building Vent sample that was lost represents 1/24 of the sampling time for the period of July to December 1987.

Any Strontium - 89 that has been detected in other Reactor Building Vent samples during this time period have all had the same value.

Therefore, the lost data most likely represents only about 4% of the total activity released.

Thus, this incident has had no affect on the estimation of error in connection with the calculation of radioactive gaseous releases from Rancho Seco Nuclear Generating Station.

METEOROLOGICAL DATA The joint frequency distributions for this report period are presented on pages 39 thru 66. This data shows the stability class wind direction and number of hours of occurrence for the indicated conditions.

This data was determined in accordance with USNRC Regulatory Guide 1.111, "Hethods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors."

Heteorological information f.'om the sites meteorological tower was used to complete the data for the joint frequency distributions.

The meteorological tower is setup and run in accordance with USNRC Regulatory Guide 1.23, "Onsite Meteorological Programs." During the third quarter of 1987, the meteorological data acquisitions system recovered 96.9% of the data. During the fourth quarter 1987, 90.4% of the data was recovered.

RANCHO SEC0 NUCLEAR GENERATING STATION VIII.

0FFSITE DOSE CALCULATION MANUAL (00CM) CHANGES A.

INTERIM CHANGE TO THE ODCM On December 9,

1987 an interim revision to the ODCM was approved.

The changes made are summarized on Table VIII-A.

l Appendix E is a copy of the interim revision.

I B.

DETERMINATION OF EFFECT OF CHANGES l

There are two changes to the Interim Revision of the ODCM which may affect the results of offsite dose calculations and monitor I

setpoints.

The bioaccumulation factor for fish was changed

{

from 1400 to 2000.

The annual uptake of fish for the I

hypothetical adult age group was reduced from 35 to 21 j

kilograms per year. In order to test the effect of these j

changes, two test runs were made using the LADTAP computer j

program.

The LADTAP computer program uses the models and I

methods as prescribed in the Offsite Dose Calculation Manual.

Both runs involved a hypothetical release of 1 Curie of Cs-137.

The test runs showed that the new factors resulted in a computed dose for the total body of the maximum hypothetical O

adult which is 9.98 % lower than the dose computed with the old factors. This reduction in computed dose is not a reduction in V

the accuracy or reliability of offsite dose calculations for I

liquid effluents.

The increase in the bioaccumulation factor i

was made because studies by Lawrence Livermore National Laboratory (LLNL) indicated that a factor of 1400 was too low.

The LLNL studies show that the bioaccumulation factors for fish in Clay Creek are similar to those used in USNRC Regulatory Guide 1.109.

The LLNL study, UCID-20295, among other things determined the bioaccumulation factor of Bluegill and Bass at several different locations.

The geometric mean of the bioaccumulation factor for these field samples was 1990.

The recommended value in USNRC Regulatory Guide 1.109

s 2000.

Thus, use of the factor 2000 increases the accuracy of the calculation.

['dm'l JULY-DECEMBER 1987 RANCHO SECO NUCLEAR GENERATING STATION B.

DETERMINATION OF EFFECT OF CHANGES - Continued The original estimate of the fish consumption factor of 35 kilograms per-year was based on the total mass of the fish caught.

Since only a portion of the fish is consumed, a lower weight is more realistic. The NRC regulatory guide value of 21 l

kilograms - per year is chosen because this more accurately reflects the actual mass of fish consumed by the maximum hypothetical user.

The monitor setpoint equations were changed so that the output of the equation would be in microCuries per cubic centimeter.

This was done because the new monitors readout in microcuries per cubic centimeter.

This change does not result in a change to the monitor setpoint other than to change units from counts per minute to microcuries per cubic centimeter.

R/.NCHO SECO NUCLEAR GENERATING STATION IX.

PROCESS CONTROL PROGRAM (PCP) CHANGES On December 1, 1987 the Plant Review Committee approved a rewrite of the Process Control Program Manual.

The PCP manual was written to conform to the format called for by Rancho Seco Administrative Procedure, RSAP-0502.

The new PCP also prevents solidification of resin from the Spent Resin Tank on the Solidification Pad until enclosure of -the Solidification Pad is completed.

Referances to other Rancho Seco procedures were also changed to ensure that the correct procedure numbers are referenced.

These changes do not provide a departure from the solidification processes used in the previous PCP (AP.309.II 4). This is because no solidification processes were changed by the rewrite of the procedure.

Therefore, this change to the PCP does not reduce the overall confermance of the solidified waste with existing criteria for solid wastes. A copy of the previous PCP, AP.309.II-4, is enclosed in Appendix H for comparison with the new PCP (RP.309.II-4).

The new PCP is enclosed in Appendix G.

RADI0 ACTIVE EFFLUENT MONITORING INSTRUMENTATION-IN0PERABILITY GREATER THAN 30 DAYS During the period of this report, both gaseous effluent monitors and the liquid effluent monitor we.e out of service.

The liquid effluent monitor was out of service due to ongoing modifications and testing of the Regenerative Holdup Tanks and associated piping. The liquid effluent monitor (R-15020) is expected to be returned to service in early 1988.

The old gaseous effluent monitors (R-15001 and R-15002) were replaced by new monitors.

The new gaseous effluent monitors (R-15044 and R-15045) have been going through testing and acceptance work throughout the last half of 1987.

Because of other scheduled work, the new monitors will be placed in service in early 1988.

XI.

CHANGE IN LAND USE CENSUS LOCATIONS The 1987 Land Use Census identified one location where there existed a potential for the calculated dose to be greater than 20 % higher than the previous years location.

The 1986 Land O-Use Census iaentified the nearest house in the West sector as being at 3,414 meters from the center of the Reactor Building.

The 1987 Land Use Census determined that the nearest residence was 2,380 meters from the center of the Reactor Building.

This change in distance would result in a 158 % increase in calculated dose from gaseous effluents over the 1986 location.

the completion of these requirements using Enclosure 8.1.
4.5 The Radwaste Solidification System is to be installwd and set up in accordance with Enclosure 8.2.
5.0 PRECAUTIONS 5.1 A new PCP test must be performed for every ten (10) liners of waste solidified from a batch, every seven (7) days of waste processing from the same batch (whichever is least), or when chemistry is outside the parameters of prior PCP tests.
5.1.1 If any test specimen fails to verify solidification; suspend the solidification of the batch under test until such time as additional test specimens can be obtained, alternative solidification parameters can be determined in accordance with the PCP, and a subsequent test verifies solidification.
Solidi fication of the batch may then be resumed using the alternative solidification parameters determined by the PCP.
O 5.1.2 If the initial test specimen from a batch of waste fails to verify solidification, collect and test representative test specimens from each consecutive batch of the same type of wet waste until at least 3 consecutive initial test specimens demonstrate solidification.
The PCP shall be modified as required, as provided in Specification 6.15, to assure solidification of subsequent batches of waste.
5.1.3 To ensure these requirements are met, a date and numbering system in conjunction with the Liner Index Log shall be~used.
5.1.4 This system will consist of the date of the latest PCP test and the number of liners solidified under the most current PCP test adjacent to the liner's container ID number.
5.2 Protective coverings will be placed over nearby manways and storm drains to prevent contamination in case of an accidental spill during the solidification or waste transfer process.
i 5.3 Ensure adequate and appropriate protective clothing and safety equipment is available at the solidification area.
Familiarize yourself with the location of the nearest eye wash and safety shower, and how to use them.
i 5.4 Do not preload chemicals into the liners except within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months befor's solidification.

3.1 BATCH
A tank of waste where the chemistry and radiochemistry will remain constant (ie. no additions are made to the tank).
3.2 SOLIDIFICATION
The process by which loose waste (i.e., water or resin) is made into a solid mass to meet transportation and disposal requirements.
3.3 PCP TEST:
A chemical analysis in accordance with the Process Control
(
Program procedure (PCP) to ensure the chemical process of
(
solidification is complete so the waste will meet all regulatory requirements.
3.4 PCP:
Process Control Program for solidification of Resin or Water as defined by TS 6.15 using cement with PNSI Radwaste Solidification System.
The PCP procedure consists of:

the sa e
.nhichever is least), or when chemistry is outside the paramet m u prior PCP tests.
5.1
.1 If any test specimen fails to verify solidification; suspend the j
solidification of the batch under test until such time as additional test specimens can be obtained, alternative solidification parameters can be determined in accordance with the PCP, and a subsequent test verifies solidification. Solidification
)
of the batch may then be resumed using the alternative i
solidification parameters determined by the PCP.
5.1
.2 If the initial test specimen from a batch of waste fails to verify solidification, collect and test representative test specimens from each consecutive batch of the same type of wet waste until at least 3 consecutive initial test specimens demonstrate solidification.
The PCP shall be modified as required, as provided in Specification 6.15, to assure solidification of subsequent batches of waste.
5.1
.3 To ensure these requirements are met,'a date and numbering system in conjunction with the Liner Index Log shall be used.
5.1
.4 This system will consist of the date of the latest PCP test and the number of liners solidified under the most current PCP test J
adjacent to the liner's container ID number.
5.2 Protective coverings will be placed over nearby manways and storm drains to prevent contamination in case of an accidental spill during the solidification or waste transfer process.
5.3 Ensure adequate and appropriate protective clothing and safety equipment is available at the solidification area.
Know the location of the nearest eye wash and safety shower, and how to use them.
5.4 Do not preload chemicals into the liners except within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months before solidification.
5.5 Liners must be vented within the last 10 days prior to shipment.
5.6 A file shall be maintained containing copies of the information sheets, radiation surveys, enclosures, records, and forms prepared for each radioactive waste liner.
5.7 For Waste containers that have the potential to radiolytically generate combustible gases (contains water and/or organic materials), a determination must be made which addresses the factors affecting gas generation, as to whether the criteria stated below ars met.
5.7
.1 Over a period of twice the expected shipment time:

.l.2 Inert to ensure oxygen limited to 5% by volume.
5.7
.2 The above is not required if the waste is low specific activity (LSA) material,jl0 shipped within 10 days of preparation (sealing) l A
or venting.
6.0 PROCEDURE 6.1 Obtain a representative sample of the waste.
Ensure that the waste was recircu'.ated (liquid) or mixed (resin) for at least four (4) hours prior to sampling.
Refer to A.22, New and Spent Resin System, Section 5.31 for sampling the spent Resin Tank.
6.2 Determine an acceptable solidification process in accordance with.1.
1 6.2
.1 Tritium, gross beta, gama emitters, boron concentration, and pH j
must be quantified before liquid solidification.
6.2
.2 The sum of the individual gama emitters compared to the gross beta should be within a factor of five or the tank shall be resampled.
6.2
.3 If upon resample, the comparison still exceeds a factor of five, an investigation of the source and composition of beta emitters is necessary.
6.2
.4 Gama emitters must be determined before resin solidification.
NOTE:
Experience has shown for liquids with a gama activity sum greater than 0.2 pCi/mi could yield dose rates greater than 10 mrem /hr at 2 meters f rom vehicle.
