CNRO-99/00018 Attachment Page 1 of 1 Year 2000 Readiness Disclosure This Year 2000 Readiness Disclosure is made for Arkansas Nuclear One - Units 1 and 2, Grand Gulf Nuclear Station, River Bend Station, and Waterford Steam Electric Station -
Unit 3 under the " Year 2000 !nformation and Readiness Disclosure Act"(Public Law 105-271).
This disclosure addresses the Y2K readiness of these facilities with regard to those systems within the scope of the license, NRC regulations, and other systems required for continued operation of the facilities after January 1,2000. A facility that is "Y2K Ready" has followed a prescribed program to identify and resolve Y2K issues so the facility can operate reliably while meeting commitments.
Entergy has conducted a Y2K readiness program similar to that outlined in NEl/NUSMG 97-07, Nuclear Utility Year 2000 Readiness. The program applies to software, hardware and firmware whose failure due to a Y2K problem would prevent the performance of the safety function of a structure, system or component. Additionally, the program applies to any software, hardware, or firmware whose failure due to a Y2K problem would prevent continued operation of the nuclear facility well beyond December 31,1999. The Entergy program also includes identifying and, where appropriate, remediating embedded systems.
The program provides for risk management efforts and development of contingency plans for key rollover dates.
In accordance with Entergy's Y2K readiness program, those systems required for operation of Arkansas Nuclear One - Units 1 and 2, Grand Gulf Nuclear Station, River Bend Station, and Waterford Steam Electric Station - Unit 3 are Y2K ready. Further, contingency plans have been developed to mitigate the impact of Y2K-induced events at key rollover dates.
