SUMMARY

.1992-2 SEMI-ANNUAL RELEASE REPORT i

The Semiannual Effluent Release Report is submitted to the United States Nuclear i

Regulatory Commission (NRC) every six months in accordance with the Oyster Cmek f

Nuclear Generating Station (OCNGS) Technical Specifications (Tech Specs). It Summarizes the radioactive gaseous and liquid effluents released and solid radioactive wastes shipped from the OCNGS. In addition, meteorological data are presented in joint frequency tables per atmospheric stability class.

Attached Tables show that doses based on quantities of radioactive material released were all less than 1 % of the limits allowed by the OCNGS Tech Specs. Limits for the release of radioactive effluents at OCNGS are based upon offsite exposure to members of the general-public. These limits were compared to dose projections calculated using the methodology in the Offsite Dose Calculation Manual (ODCM). There were no liquid releases from OCNGS

.l during the period. Solid waste shipments were similar to those of nuclear plants of comparable type, age and size. Concrete was used for solidiGeation material during the reponing period. The report summarizes the fact that all effluents mleased were within j

federal regulatory requirements of the OCNGS Technical Speci6 cations.

l t

i A summary of Oyster Creek's meteorological data is provided in tabular fonn. Also included is a description of changes made t the Offsite Dose Calculation Manual (ODCM) and the Pmeess Control Plan (PCP) during the reporting period. Ef0uent monitoring instruments that were inoperative as per Technical Specification 3.15 for the reporting period i

a e also discussed.

OYSTER CREEK NUCLEAR GENERATING STATION LIQUID EFFLUENT RELEASES Third and Fourth Quarters 1992 Oyster Creek Nuclear Generating Station policy is to strive for zero liquid discharge of radioactive material.

As a result, there were no liquid continuous or batch releases from OCNGS in the second half of 1992.

Oyster Creek Nuclear Station 1992-2 Semi Annual Effluent Report Changes to the Offsite Dose Calculation Manual:

-l No changes were made to tne ODCM during this time period.

r Changes to the Process Control Plan:

The Process Control Plan procedure for Transfer, Solidification, and Dewatering of Solid Wet Waste was modified in October. Valving procedures already used per operator experience but not explicitly l

specified in the procedure are now identified and controlled by a valve check off.

i Effluent Monitors Out of Service Greater than 30 Days:

During the second half of 1992 three instruments were out of service for longer than 30. days:

1 The Overboard Discharge Monitor was long out of service and was being refurbished during July and August. The instrument was placed l

into service in August. No overboard discharges occurred during the period from July through August when the instrument was out of service.

The Service Water Rad. Monitor was not declared operable as a result of repeated failures, air binding and biological fouling.

The monitor is being evaluated for return to service.

Daily discharge samples are collected as required while the monitor is out of service.

i The AOG vent monitor was out of service from November until the end of the reporting period due to sample tubing leakage. Tubing repair is scheduled.
