Abstract
It is thus the purpose of this work to investigate the nature of input parameter variation-induced effects on the extinction probabilities of certain types of nuclear assemblies. A broadly defined class of mathematical analysis techniques known as sensitivity analysis (and in particular, a theoretical construct known as the Gâteaux-variation) will be employed to calculate these effects. The analysis will be left as general as possible within the context of a clean, stochastic point model, though examples of interest to the consideration of fast reactors near start-up time will also be considered. In addition to providing situation-specific information regarding input parameter influence on the start-up behavior of fast reactors, the primary goal of this work is to maximize the usefulness of the generalized developments as applied to other potential problem classes of interest.
