Interpretation of Local Flux Measurements in Subcritical Systems and Reactivity Determination

Table 4

Percentage relative error on the flux at position 𝑥₁ and time 𝑡=10ms during transient T1 with different localizations of the adjoint source for the definition of the lpk model adopted. In bold, the result obtained when the adjoint source is located where the detector is (spatially and energetically).
