, RADloAl'r[VE EFFLUENT RFI FASE REPORT 1996 SOUTH TEXAS PROJECT l Introduction and Summary '

INTRODUCTION This Annual Radioactive Effluent Release Report is submitted for the period January 1,1996,  ;

through December 31,1996, in accordance with Appendix A of License Nos. NPF-76 and NPF-80, Technical Specifications and the Offsite Dose Calculation Manual.

A single submittal is made for both units combining those sections that are common. Separate >

tables of releases and release totals are included where separate processing systems exist.

This report includes an annual summary of hourly meteorological measurements taken during each quarter. This data appears as tables of wind direction and wind speed by atmospheric stability class. All assessments of radiation doses are performed in accordance with the Offsite l Dose Calculation Manual.

Minimal quantities of radioactivity were released during 1996. Liquid effluents are discharged to the onsite Main Cooling Reservoir and subsequently released offsite. The radioactivity released in liquids beyond the site boundary was estimated using the South Texas Project Electric Generating Station Offsite Dose Calculation Manual. Solid radioactive waste is shipped offsite i for disposal. The following table is a brief summary of the radioactive effluents and solid waste attributable to the station.

Tritium accounted for the largest fraction of the radioactive effluents both liquid and gaseous.

Tritium was the largest contributor to the offsite doses from radioactive effluents. The offsite doses are well below any regulatory limit and significantly less than the average annual radiation exposure to people in the United States from all sources (360 millirem).
