VAR 2 5 2008 L-2008-058 FPL IOCFR50, Appendix E US Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC, 20555 Gentlemen, Re: Turkey Point Unit 4 Docket Nos. 50-251 Emergency Response Data System (ERDS) Maintenance This letter is being submitted pursuant to 10CFR50, Appendix E, VI, 3.b (Maintaining the Emergency Response Data System) for Turkey Point Unit 4 (TP4) due to ERDS Point ID revisions.
Turkey Point Unit 4 (TP4) will be undergoing a major modification (i.e., replacement) of the Emergency Response Data Acquisition and Display System (ERDADS) during the spring, 2008 Refueling Outage. The ERDADS is the plant computer system that supplies the ERDS data points (as described in NUREG-1394, Revision 1).
The TP4 ERDS Data Point Library (DPL) will retain all the original data points (i.e., 59 data points) but will revise the Point IDs to a format that has been established for the new Distributed Control System (DCS) configured ERDADS (see Attachments 1 & 2). This Point ID change will affect the ERDS transmission format and computer communication protocol, therefore NRC notification is required 30 days prior to implementation. This will require ERDS DPL point ID updates for TP4 by NRC personnel.
Associated "detail" data for several of the points has also been updated to reflect current plant configuration as well as enhancements gained from DCS display capabilities. This too will require ERDS DPL updates for TP4 by NRC personnel.
PTN will coordinate the ERDS Point ID change-over and testing with the NRC Operations Center following installation and verification of the new DCS ERDS points.
This is anticipated to be towards the end of April, 2008 and prior to TP4 resuming plant operation following the outage.
Current scheduling for outage work on the ERDADS (and ERDS) is from April 1st, 2008 through May 2nd 2008. This activity will be separately communicated to the NRC just prior to the plant outage in accordance with 10CFR50.72 (b) (3) (xiii) and will include notification of the NRC resident inspector and any follow up notifications as may be required.

This information is being provided for both compliance to 0OCFR50, Appendix E, VI, 3.a and 3'b requirements and to support implementation by the NRC of the new TP4 ERDS Data Point IDs.
