' TXU Electric's Response to Generic Letter 98-01, Supplement 1:
This disclosure addresses the final Y2K readiness status 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.
TXU Electric has conducted a Y2K readiness program similar to that outlined in Nuclear Utility Year 2000 Readiness. NEI/NUSMG 97-07. The program epplies to j
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 and the continued operation of the nuclear facility well beyond December 31,1999. The program provided for risk management efforts and development of contingency plans i
for key rollover dates.
The.Y2K readiness program has been completed through the detailed assessment, remediation and contingency phases for those systems required for operation of the j
CPSES facility. The following open remediation items are now considered closed and i
the facility is declared Year 2000 Ready.
- Unit 1 - Condensate Polishing Programmable Logic Controller System This non-safety related Year 2000 modification has been implemented successfully during the Unit 1 Refueling outage, and as such the system has been declared Year 2000 compliant as of September 30,1999. This system is necessary for secondary
- plant chemistry control.
Common Facility - Plant Simulator Rehost Proicct This project entailed complete rehost of the CPSES Plant simulator. This item does not affect plant operations or plant safety. Existing processes are already in place to conduct operator training in the event the simulator is not available for any reason, including potential Year 2000 induced failures or should the remediation strategy fail.
This project was scheduled to be completed by October 30,1999.
l
r1 Enclosure to TXX-99229 Page 2 of 2 During the remediation phase, it was decided that due to vendor delays beyond TXU control, and the risk of not completing the rehost project in a timely manner, an alternate remediation plan was implemented in parallel. The alternate remediation plan entailed backdating of the plant simulator, verifying proper operation, and operating the simulator in dates earlier than the Year 2000 to avoid encountering Year 2000 issues. This alternate remediation has been implemented and the plant simulator has becit declared Year 2000 Ready as of September 17,1999.
