Washington, DC 20555 MONTICELLO NUCLEAR GENERATING PLANT Docket No. 50-263 License No. DPR-22 Completion of Commitments Associated with NRC Generic Letter 87-02 Supplement 1 USI A-46 Seismic Evaluation Report (TAC M69460)

Ref.1: Letter from William J. Hill, NSP, to US NRC Document Control Desk, " Supplemental Response to Supplement 1 to Generic Letter 87-02, Verification of Seismic Adequacy of Mechanical and Electrical Equipment in Operating Reactors, Unresolved Safety issue USI A-46"(TAC M69460)," February 19,1996 Ref. 2: Letter from William J.

3. Outlier components identified in Table 1-3 of Attachment 1 are to be replaced with relays seismically qualified for theirintended use during the Monticello 1998 refueling outage, currently scheduled to commence in January 1998.

By Reference 2, NSP provided the NRC an update on the status of the outliers and informed the NRC that commitment 2 was completed during the 1996 refueling outage.

l The purpose of this letter is to inform the NRC that commitments 1 and 3 were completed by the l end of the 1998 refueling outage. These commitments involved final disposition of the j remaining outlier components. With completion of outlier dispositioning, all known outstanding '

I work associated with unresolved safety issue A-46 at Monticello has been completed.

In reviewing closeout of this issue, an error was identified in Reference 2 that we wish to correct at this time. As stated in Reference 1, commitment 1 was to be completed during the 1998 refueling outage which at that time was scheduled for January 1998. In Reference 2, commitment 1 is incorrectly quoted calling for completion by January 15,1998. Because of the i extended 1997 outage for v>ction strainer modifications, the 1998 refueling outage was  !

rescheduled from January to March and April 1998. Commitments 1 and 3 were therefore completed by April rather than January as inferred in Reference 1, but erroneously stated in Reference 2.
