- 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.
