Reference (a) contains a data reversal and a typographical error in Table 1 l

l Critical Boron Heasurements. The predicted and measured values for CEA Croups 1 l

through 5 Inserted Zero Power, are reversed. Also the predicted value for Full Power should have been reported as 1302, not 1303. All analytical work and j

review / acceptance criteria were performed using the correct values. Attached is the corrected page.
