Interpretation of Local Flux Measurements in Subcritical Systems and Reactivity Determination

Figure 1

Power evolution following a source pulse in a subcritical system ( ), simulated with different approaches to point kinetics: cpk and gpk. Solid line: reference; dashed line: point kinetics. The inset graphs represent the shape and the weight adopted (m.a.t.: mean absorption time = ).
