  • For only the fuel movements required to replace neutron sources, the count rate may be reduced to 0.3 counts per second prior to achieving a burnup of 2000 MWD /T onAfter the first core provided the signal-to-noise ratio 22.

a burnup of 2000 MWD /T, the count rate must be at least 0.7 cps provided the signal-to-noise ratio i s >._2 .

Otherwise 3 cps.
