Some Additions to Reactor Noise Theory Which Include Delayed Neutrons

The general theory of reactor noise in the time domain for a zero-power reactor is formulated by using an equation for the probability generating function (pgf). With suitable manipulations of the pgf, several previously known theoretical results from noise analysis in the time domain can be deduced from this general theory. Although the detection process is not treated generally, a new result is the explicit determination of the pgf for the case where delayed neutrons are considered.
