1 Entergy Operations, Inc. --, River Road Killona, LA Tel W3F A4.05 PR March 30, 2001 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C Subject: Waterford 3 SES Docket No License No. NPF-38 ERDS Data Point Library (DPL) Changes Gentlemen: Entergy is hereby notifying the NRC Staff of updates to the Waterford 3 Emergency Response Data System (ERDS) Data Point Library (DPL), in accordance with 10 CFR 50 Appendix E.VI.3.a. Attached are updated DPL reference file pages reflecting changes made affecting five NRC ERDS parameters. The changes to two of the parameters (RCS LTDN RAD and COND A/E RAD) were not reported within the required 30-day period. This is being addressed within the Waterford 3 Corrective Action Program (CR ). If you have any questions, please contact 0. Pipkins at (504) There are no commitments contained in this submittal. Very truly yours, A. J. Harris Director Nuclear Safety Assurance AJH/OPP/cbh cc: E.W. Merschoff (NRC Region IV), N. Kalyanam (NRC-NRR), J. Smith, N. S. Reynolds, NRC Resident Inspectors Office SAo%22{

2 Description of ERDS Data Point Library (DPL) Changes NI SOURCE RNG Nuclear Instr Source Range Changed the Minimum Instrument Range, as well as the Cut-off and Turn-on Power Levels to their proper values. EFF GAS RAD Radioactivity of Released Gases Replaced the point for this parameter. The current point is Plant Stack Gas Radiation in engineering units of uci/cc. The new point is Plant Stack Gas Radiation Release Rate in engineering units of uci/second. COND A/E RAD Condenser Air Ejector Radioactivity Replaced the point for this parameter. The current point is from a radiation monitor that has been removed. The new point is a radiation monitor that provides the same information. CNTMNT RAD Radiation Level in Containment Replaced the point for this parameter. The current point is Containment Area Radiation in engineering units of mr/hr. The new point is Containment High Range Area Radiation in engineering units R/HR. RCS LTDN RAD Rad Level of RCS Letdown Line No point will be provided for this parameter. The current point is from a radiation monitor that has been removed. There is no other point available which provides this information.
