SUBJECT:

JULY - DECEMBER 1993 SEMI-ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT In conformance with the Nine Mile Point Nuclear Station Unit 1 (NMP1) Technical Specifications, we are enclosing the Semi-Annual Radioactive Effluent Release Report for the reporting period July - December 1993. Included in this report is a summary of gaseous, liquid and solid effluents released from the station during the reporting period (Attachments 1-6), a summary of revisions to the Off-Site Dose Calculation Manual and the Process Control Program during the reporting period (Attachments 7 and 8), and an explanation as<<to the cause and corrective actions regarding the inoperability of any station liquid and/or gaseous effluent monitoring instrumentation (Attachment 9).

Attachments 10 and 11 provide a summary and assessment of radiation doses to members of the public within and outside the site boundary, respectively, from liquid and gaseous effluents as well as direct radiation.

The format used for the effluent data is outlined in Appendix B of Regulatory Guide 1.21, Revision 1.

Dose assessments were made in accordance with the NMP1 Off-Site Dose Calculation Manual.

Distribution is in accordance with Regulatory Guide 10.1, 10CFR50.4(b)(1) and the Technical Specifications.

Included in the report is an update of actual data for the month of June used in the second quarter of the January - June 1993 Semi-Annual Radioactive Effluent Release Report; an updated Attachment 6, "Solid Waste and Irradiated Fuel Shipments," for January - June 1993.

During the reporting period from July - December 1993, NMP1 did not exceed any 10CFR20, 10CFR50 or Technical Specification limits for gaseous effluents. There were no liquid releases during the reporting period from NMP1. An independent technical evaluation of the off-site vendor analyses performed by Niagara Mohawk Power Corporation has indicated a potential for a discrepancy in the data results.

The resident inspectors at Nine Mile Point have been informed and corrective actions initiated. The evaluation is continuing and future Semi-Annual Radioactive Effluent Release Reports will reflect any changes as a result of this technical evaluation.

If you have, any questions concerning the attached report, please contact Ms. Elizabeth D. Thomas (315) 428-7188, or Anthony M. Salvagno (315) 428-7189, Chemistry and Radiation Protection Support, Salina Meadows.
