“…83 There was no estimate of the accuracy of experimental methods for this particular category, but data should not deviate significantly from that on an assembly-wise or local axial basis. 88 Similarly, a ±2.3% standard deviation was obtained in predictions of assembly-averaged power distribution for the Kewaunee reactor. 8 * For the San Onofre reactor, power distributions were measured experimentally by aeroball activation, and a ±6.2% standard deviation in assembly-averaged power distribution prediction was reported.…”
