Abstract :
The precision of reactor noise techniques for measuring subcritical reactivity can be related to detector efficiency and parameters of the measuring instrumentation. Using a two-detector cross-correlation technique, we have determined that such measurements can be made in a certain fast reactor (the FFTF) to -3 to -5 dollars with acceptable statistics and measurement times.
