This paper deals with the simulation-based design optimization and experimental validation of thecharacteristics of an in-core silver Self-Powered Neutron Detector (SPND). Optimized dimensions of theSPND are determined by combining Monte Carlo simulations and analytical methods. As a first step, theMonte Carlo transport code MCNPX is used to follow the trajectory and fate of the neutrons emitted froman external source. This simulation is able to seamlessly integrate various phenomena, including neutronslowing-down and shielding effects. Then, the expected number of beta particles and their energyspectrum following a neutron capture reaction in the silver emitter are fetched from the TENDELdatabase using the JANIS software interface and integrated with the data from the first step to yield theorigin and spectrum of the source electrons. Eventually, the MCNPX transport code is used for the MonteCarlo calculation of the ballistic current of beta particles in the various regions of the SPND. Then, theoutput current and the maximum insulator thickness to avoid breakdown are determined. The optimumdesign of the SPND is then manufactured and experimental tests are conducted. The calculated designparameters of this detector have been found in good agreement with the obtained experimental results
