IGentlemen-L

' On May: 23,1990, the Virgil C. Summer Nuclear Station (VCSNS) submitted the I

Core Operating Limi.ts Report (COLR)' for the' Cycle 6 core.. Since this i

l, submittal, South Carolina Electric & Gas Company (SCE&G) has discovered a t

L typographical error in Figure 14 (Page 27) of the Report.

In the figure-

- RCS Total Flow Rate Versus R for Three Loop Operation," the data points are labeled to avoid uncertainties in reading the-. graph.

When.these points were.

L marked;:.the curve for 92% Rated Thermal Power (RTP) was mislabeled.;

The correct indices of the_ breakpoint at 92% RTP are:.. (1.00,27.79).

Due to a typographical error, however, the subject point was' mislabeled in the COLR

'as:,(1.00, 28.79).. The curve defining the region of. acceptable operation at 92%' RTP was correctly drawn in the original COLR submittal.

Only the error.

~3 in labeling needs to be revised.

w This correction is the first1 revision'to the VCSNS Cycle 6~COLR.

Attachment 1 contains the corrected Figure 14 for the report.

Also provided in
