RSN3s SEMANNuAL RAD 60ACirVE EFFLUENT RELEASE REPORT JULY DECEMBER trrJO INTRODUCTION Rancho Soco Nuclear Generating Station (RSNGS) Unit No.1 is located in Sacramento County, Caldomia approx:r" atty 25 miles southeast of Sacramonto and 26 miles north. northeast of Stockton. Rancho Seco Unrt No.1 bogan commercial operation on April 17,1975. The single unit on the Rancho Soco sito is a pressurized water reactor supplied by Babcock and Wilcox.

The rated capacity is 963 gross megawatts oloctrical. Because of a public vote on June 6, 1989, the Distnct shutdown the Rancho Soco Nuclear Gonorating Station and comploted dotuoling operations tsn December 8,1989.

This Semiannual Radioactivo Effluent Roloase Roport (SRERR) provides a summary of gaseous and liquid offluent releases made from Rancho Seco during the penod July 1 through December 31,1990. Also prosented in this report is the projected radiological impact from those releases and a summary of solid radwasto shipments.

This report has been prepared by the Sacramonto Municipal Utility Distr 6ct to moet the requirements of Rancho Soco Technical Specification 6.9.2.3. It is presented in accordance with the format of USNRC Regulatory Guido 1.21. The radiation dosos reported in this SRERR are calculated for a hypothetical individual who receives the maximum possible exposure at or beyond the Site Boundary.

Releases of radioactkity in gaseous and liquid offluents during this report period did not exceed the limits of 10 CFR 20 or the numerical guidelines of 10 CFR 50, Appendix 1. A 40 CFR 190 dose evaluation is not required because radioactive effluent releases did not excood twice the numerical,uidelines of 10 CFR 50, Appendix 1.

4 HsNGs e AANNVAL RADICAcTNE EFrLUEW AELEAsE REPORT JULY, DECEMBER 1990 E,

UNPLANNED RELEASES This section describes unplanned releases of radioactkity in liquid and gaseous offluent.

Norma:ty, expected plant evolutions described in the Updated Safoty Analysis Report (USAR) which may happen without notico such as Main Steam Safety Rolief lifts following a plant trip ate considered ' planned' and will not be discussed.

Gnwous Betwoon September 1990 and November 6,1990, the pressure in the B Wasto Gas Decay Tank (WGDT) dropped from 50 psig to 8 psig, according to Operations' Logs. This drop in pressure was caused by a leakage through the B WGDT reliot valvo, to the waste gas surgo tank. The gas from the B WGDT was eventually released to the atmosphoto via the Auxiliary Building Stack (ABS) Since the gassos left through the ABS, the release was monitored. When the drop in pressure was discovered, the tank's contents woro sampled and anatyzod, and the remaining gas in the tank was released as a normal WGOT release.

The actNity released as a result of the leak was conservatkoly estimated as:

Kr-85 1.42E 01 Ci H-3 5.07E 05 Ci The resulting exposure to the most limiting rocoptor (Child, Liver) was calculated to be 1.39E-07 mrom or 0.00000093 porcent of the annuallimit provided for in Technical Specifications. The cause of the event was the leaking relief vaNo. Investigation is underway to determine the exact path of the leakage. The system will be placod in a layed up condition vented to the ABS, so no action to provent recurronce is required in the permanently defuelod condition.

khN.d 1.

On July 26,1990 a tank farm storm drain was uncovered to facilitato the drainage of rainwater. Sometime between July 20,1990 and October 19,1990 a catch containment was removed from a previously leaking foodwater lino in the tank farm.

The containment was removed because the system had boon put into dry layup and leakage had stopped. Subsequently, valve backleakage from the Steam Gonorator in wet layup caused the leak to recur. The leak was discovered in October 19,1990 and a new catch containment was immediately installod. The leak left sito through the uncovered storm drain and eventualty to the plant effluent. The leak rate was I

estimated at 0.038 gallons per day, and the release volume was conservativoty estimated at 3.28 gallons. The actNity released was conce.",?tively estimated as:

H3 1.14E-07 Cl Cs 134 9.77E 09 Cl Cs 137 8.88E 07 Cl The resulting exposure to the most limiting receptor (Adult Total Body) was calculated to be 2.85E 05 mrom or 0.00095 porcent of the annual limit provided for in Technical Specifications. The cause of the event was backleakage through isolation vanes.

Additional isolation valves were shut, stopping the backloakage from the Steam -

Gonorator, which stoppod the leak. Additional programmatic action to provent l

recurrence was not necessary.

A body.to bonnet leak developed on December 25,1990, on a vane located on the Tritium Evaporator at the rato of approximately 2 gpm. The leak was conservatively estimated to have lasted for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> before it was isolated, resulting in a release of 480 gallons. The leak left site through a storm drain to the field south of the plant and eventually to Hadselville Creek. The amount of activity released was j

conservatively estimated as:

H4 6 98E 02 Cl Cs 137 6,52E 08 Ci l

The resultant dose to the most restrictive receptor (Child Total Body) was calculated to be 7.64E 04 mrem or 0.025 percent of the annuallimit provided for in Technical Specifications. The cause of the incident was damage to the valve due to an extended period of below design basis freezing temperatures, and programmatic action to prevent recurrence was not necessary.

RADIOACTIVE EFFLUENT MONITORING INSTRUMENTATION INOPERABLE FOR -

OREATER THAN 30 DAYS There were no instances of Radioactive Effluent Monitoring Instrumentation inoperability in excess of 30 days in the reporting period.

G.

METEOROLOGICAL INSTRUMENTATION INOPERABLE FOR OREATER THAN SEVEN DAYS On December 17.1990, the 60 Meter Channel A & B Wind Direction instrument, and tho 60 Meter Channel A & B Wind Spoed Instrument became inoperable when plant operators were unable to verify acceptable operation of the instruments. The Channel A Wind Direction support was accidentalt/ bumped when chocking it, resulting in misalignment.

The Wind Direction instrument inoperability was caused by a looso connector at tho sensor.

On Docomber 18,1990, the 10 Meter Channel A & 8 Air Temperature instrument became inoperable when plant operators were unable to verify acceptable operation of the instrument. The inoperability was caused by the RTD range being outside of the acceptablo calibration range of the electronics, On December 22,1990, the 10 Meter Channel A & B Wind Direction Instrument became inoperable when plant operators were unable to verify acceptable operation of the instrununt. The inoperabilit}y of the instrument was caused by the difference betwoon the channels being larger than the maximum allowed difference for acceptability,.

Work requests have been initiated on all affected Meteorological Instruments, and we k is expected to be completed early in the next repo_rting period.

MAJOR CHANGES TO THE RADWASTE TREATMENT SYSTEM A major change occurred to the Radwaste Treatment Systom. This change consisted of the purchase and installation of the AVR 800 Blonder /Dryor, The unit was purchased ouring the I

first six months of 1990 and has boon undergoing installation, piant spocific design modifications to interface with plant auxiliary and support systems, and overall process testing. The Blondor/Dryor has not currently boon fully incorporated into the facility's radwaste procosting scheme and will not be until final system testing and acceptance which is anticipated during the first quarter of 1991. The incorporation of the Blonder /Dryor into the radw6sto processing schemo at the facility will result in an overall roduction in the total radwasto disposal volume with an anticipated volume reduction for the liquid waste stream of 8:1. The Blender /Dryor will be extensivoty utilized to process the liquid radwasto stream by evaporating off the liquid constituont and leaving the remaining solid procipitato behind to be incorporated into a paraffin matrix which will then be packapod and disposed of as low lovel radwaste at a licenced disposal facility. This process will replace the outmoded coment solidification processing technique which resulted in a volumo increasing operation during processing and has como under increased scrutiny by the NRC in rocent months. The Blondor/Dryor process will result in fewer radwasto shipments for disposal and will have an overall effect of decreasing the potential of a transportation accident during i

disposal transport incorporation of the Blondor/Dryor process will not reduce the overall conformance of the end waste product. Appropriate procedural changes have boon initiated to ensure the necessary end wasto product inspection crttoria are mot and comply wnh the appropriato regulatory requirements. The required procoduro changes have boon identified and are currently in the review process prior to implomontation. The Blonder /Dryor will not be considered fully functional and in-place until unit testing and final acceptance are complete, Documentation of the change to the radwaste systems as a reek of the purchase and installation of the Blender /Dryor has been provided by the Design Change Package (DCP l

R90-001) 50,59 review and acceptance by the Plant Review Committoo (PRC).

Table V-8, Uquid Effluents, provides a complete quarterty summary of the amount of radioactivtty (Cl) released per radionuclide in each quarter Data is provided for fission and activation products, and for dissolved and entrained gases. Tritium and gross alpha are not included in this table (they are listed in Table V.A). Since no continuous releases of liquid radioactive effluent are made from RSNGS, data is provided onY for batch teleases.

Table V C, Uquid Effluents Typical Lower Umits of Detection, provides a listing of the typical lower limit of detoction (LLD) concentrations in pCl/ml for various radionuclides.

Table V D, Radiologeal Impact on Man Due To Uquid Effluent Releases, provides a summary of calculated radiation doses delivered to a maximum exposed hypothetical individual at the Srto Boundary for liquid effluents (actual doses will be assessed in the 1990 Annual REMP Report).

The maximum calculated total bod / dose and organ dose for quarter 3 and quarter 4 are listed. A comparison versus Technical Specification dose limits is also presented.

~

TM meteorological data for Rancho Seco Nuclear Generating Station for Quarter 3 an of 1990 is presented in this section. A joint frequency distribution (JFD) table indicates number of hours in a quarter at each combination of wind speed and direction for a g atmospheric stability class. : Included are JFD tables for each separate stability c composite to summartze all classes, The data is dMded further to account for the mode of release, Continuous release data account all hourfy averages in the entire quarter. Batch release meteorology takes into a only those hours during which batch releases occurred. Batch release meteorolo monitorod_ gaseous batch releace hours and abnormal gaseous release hours. This discrepancy between the total hours of batch releases in this section versus the v the ' Batch Releases

summary table (Section I, part D).-

'The following meteorological data was determined in accordance with USNRC Regul 1.111,' Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Ef Routine Releases from Ught Water Cooled Reactors. Meteorological information from meteorological tower was used to complete the data for the JFDs. The meteorologk:al

- acquisitions system recovered 0.57% of the data for Quarter 3 and 88.27% of th 4 of 1990, and 93.52% of the data was recovered for calendar year 1990 Measurem meteorological tower have been made in accordance with USNRC Regulatory Gui Meteorological Programs, e
