Emny Conpan APR 2 3 2003 SERIAL: BSEP 03-0066 10 CFR 50, Appendix E rA.. Nuclear Regulatory Commission ATIN: Document Control Desk Washington, DC 20555-0001 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-325 AND 50-324/LICENSE NOS. DPR-71 AND DPR-62 NOTIFICATION OF EMERGENCY RESPONSE DATA SYSTEM MODIFICATION Ladies and Gentlemen:
On June 9, 1992 (Serial: NLS-92-140), Progress Energy Carolinas Inc. (PEC) submitted the Emergency Response Data System (ERDS) Data Point Library for the Brunswick Steam Electric Plant, Units 1 and 2. In accordance with 10 CFR 50, Appendix E, Section VI.3.a, this letter provides notification of a change to a transmitted data points in the Unit 1 and Unit 2 ERDS Data Point Libraries.
As a result of installation of a new digital Power Range Neutron Monitoring (PRNM) system on Unit 2, the number of Average Power Range Monitor (APRM) inputs to data point C51CO010, "NI POWER RNG," was changed from six to four. This change was implemented on March 30, 2003.
Also, on March 30, 2003, PEC implemented extended power uprate on Unit 2. As a result, the "Engr Units Conversion" field for data point C51C0010, has been revised to reflect the uprated thermal power level.
PEC also upgraded the feedwater control system. As a result of this modification, maximum instrument range for data point C51C8003, "MAIN FD FLOW," was changed from 0.120E+02 to 0.160E+02 and a note was added to indicate that this is the actual field instrument range. This modification was completed on March 29, 2003. A similar change to the instrument range for Unit 1 data point C51C8003 was made in March 2002.
The enclosure to this letter provides revised Data Point library Reference File sheets for Unit 1 data point C51C8003, and Unit 2 data points C51C0010 and C51C8003.
