SUBJECT:

JANUARY - JUNE 1994 SEMI-ANNUALRADIOACTIVE 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 January - June 1994. 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).

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 December used in the fourth quarter of the July

- December 1993 Semi-Annual Radioactive Effluent Release Report and an updated Attachment 6, "Solid Waste and Irradiated Fuel Shipments", for the periods January - June and July - December 1993.

During the reporting period from January - June 1994, 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.

As reported in the July - December 1993 Semi-Annual Radioactive Effluent Release Report, an independent technical evaluation of the off-site vendor analyses performed by Niagara Mohawk Power Corporation (NMPC) identified a potential for a discrepancy in the data results. Based on the evaluation results, NMPC has determined that the analytical errors affected NMP1 solid waste data for the period June 1992 - October 1993. There were no effects on gaseous or liquid effluent values. Changes resulting from these analytical errors were found to be within the guidance provided in the United States Nuclear Regulatory Commission's Technical Position On Waste Form, Revision 1, January 1991 for scaling factors. The previously determined waste classes were not affected.

Therefore, based on the evaluation mentioned above, no changes were made to the individual associated shipping manifests. However, an update concerning activities and estimates of major nuclide composition is included in the "Update To The Previous Reports" section of this report.
