Interpretation of Local Flux Measurements in Subcritical Systems and Reactivity Determination

Table 5

Error in pcm on the subcriticality level as obtained by the different point kinetic models adopted in the one-dimensional domain sketched in Figure 10. The direct shape is assumed to be the subcritical source-driven distribution.
