==Reference:==
HL&P letter by G. E. Vaughn to USNRC Document Control Desk dated March 1, 1989 (ST-HL AE-3002) transmitting Semiannual Radioactive Effluent Release Report for Second Half of 1988 Pursuant to the South Texas Project Electric Generating Station (STPEGS)
Unit 1 Operatir;g License NPF-76 Appendix A Technical Specification 6.9.1.4 and 10CFR50.36a, the following information is issued to supplement the Semiannual Radioactive Effluent Release Report for the period July 1, 1988, through December 31, 1988, Section 3.2.2.          This report is submitted as fulfillment of             I the commitment made in Section 3.2.2 of the referenced report.
The Condenser Vacuum Exhaunt System process flowmeter N1RA-RT-8027A was removed from service on November 1, 1988 at 0100.              The actual process flow rate is consistently below the minimwr. range of the installed instrumentation hence meaningful flow measurement is not possible utilizing the installed equipment. During this period, flow estimates in accordance with Technical Specifications have been made every four hours.

The condenser vacuum exhaust will be rerouted to the unit vent where quantification of activity and flow will be,made by the normal unit vent monitor, NIRA-RT-8010A/B.       Radiation monitor RT-8027A will remain in service as a non Technical Specification process monitor.      Prior to actual implementation, applicable Technical Specification and FSAR changes shall be processed for NRC approval.
