Abstract EN
A simple method using the time-dependent Monte Carlo (TDMC) neutron transport calculation is presented to determine an effective detector position for the prompt neutron decay constant (α) measurement through the pulsed-neutron-source (PNS) experiment.
In the proposed method, the optimum detector position is searched by comparing amplitudes of detector signals at different positions when their α estimates by the slope fitting are converged.
The developed method is applied to the Pb-Bi-zoned ADS experimental benchmark at Kyoto University Critical Assembly.
The α convergence time estimated by the TDMC PNS simulation agrees well with the experimental results.
The α convergence time map and the corresponding signal amplitude map predicted by the developed method show that polyethylene moderator regions adjacent to fuel region are better positions than other candidates for the PNS α measurement.
