Interpretation of Local Flux Measurements in Subcritical Systems and Reactivity Determination
Figure 2
Power evolution following a source pulse in a subcritical system (), simulated with a lpk approach, considering two different detector locations: first row, detector far from the source (L); second row: detector close to the source (L). Solid line: reference; dashed line: point kinetics. The inset graphs represent the shape and the weight adopted.

(b) lpk and source-driven shape (: detector location)
(c) lpk and critical shape (: detector location)
(d) lpk and source-driven shape (: detector location)
