SUBJECT:

SOUTH TEXAS PROJECT, UNITS 1 AND 2 - RESPONSE TO GENERIC LETTER 98-01," YEAR 2000 READINESS OF COMPUTER SYSTEMS AT l NUCLEAR POWER PLANTS"(T/,C NOS. MA1890 AND MA1891)  !

l

Dear Mr. Cottle:

In Generic Letter 98-01," Year 2000 Readiness of Computer Systems at Nuclear Power Plants,"

and its Supplement 1, we requested utilities to submit plans and schedules for resolving Y2K-related issues. We have received and reviewed all licensees' corrective plans and schedules. Based on our review of licensee responses and our onsite assessment of licensee Y2K activities as described in NUREG 1706, " Year 2000 Readiness in U.S. Nuclear Power Plants," we have concluded that there are no nuclear plants with Y2K issues involving safety systems.

Increased public awareness and attention to the Y2K issue has resulted in concern over the ability of nuclear power plants to provide uninterrupted power to the national electric power grid during the Y2K transition, in this regard, we are focusing attention beyond those systems ,

necessary to maintain safety. Consequently, we are closely monitoring those plants having l Y2K deficiencies in systems that could impact plant operation that are not scheduled for remediation prior to September 30,1999. As you are aware, a Y2K deficiency in certain systems or components might cause a transient during the Y2K transition that could affect the national electric power grid.

In your letter of June 29,1999, for South Texas Project, Units 1 and 2, you stated the following:

The South Texas Project, Units 1 and 2, will not be Y2K ready until you make changes to the Procurement and Inventory Control System and the Integrated Computer System.

• You intend to make these system changes by the end of October 1999.

It is our understanding that at least one of the systems or components listed above, which are l currently not Y2K ready, may have the potential to cause a transient during the Y2K transition O or be important to continued power operation at your facility. The NRC considers it important to ,

complete these Y2K remediation efforts in advance of the Y2K transition date. To efficiently / ,

schedule regional inspections to verify completion of the Y2K work, y the staff of any changes in (1) the scope of the Y2K system deficiencies listed above, or /

wh g (2) your complete. projected completion schedule. Please submit a letter document ,

We would like to acknowledge the efforts you have completed to date in preparing your plant for the Y2K transition and appreciate your continued cooperation on this important issue.

The collection of this Information is covered by OMB Clearance 3150-0012 which expires on

June 30,2000. We estimate that the effort to collect this information and report back to us by letter will take approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

Please contact me at 301-415-1326 if you have any questions.
