i B17723%ttachment 1\Page 1 This year 2000 readiness disclosure is made for Millstone Nuclear Power

' Station, Unit Nos. 2 and 3, under the " Year 2000 information and Readiness l Disclosure Act" (Public Law 105-271).

This disclosure addresses the Y2K readiness of the facility with regard to those systems within the scope of the license, NRC regulations, and other systems required for continued operation of the facility 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.

Northeast Nuclear Energy Company has conducted a year 2000 readiness program similar to that outlined in Nuclear Utilitv Year 2000 Readiness.

NEVNUSMG 97-07. The program applies to software, hardware and firmware wbJse failure due to a Y2K problem would prevent the performance of the safety fu.Etion 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 facility program also includes identifying and, where l appropriate, remediating embedded systems. The program provides for risk )

management efforts and development of contingency plans for key rollover l dates.  !

i The Y2K readiness program has been completed for those systems required for operation of the Millstone Nuclear Power Station, Unit Nos. 2 and 3. To the best of my knowledge and belief Millstone Nuclear Power Station facility is "Y2K Ready." Further, contingency plans have been developed to mitigate the impact of Y2K-induced events at key rollover dates.
