Study on kinetic parameters characteristics of pebble bed reactor using HTR-proteus facility [PDF]
Nuclear Technology and Radiation Protection, 2022 The inherent safety feature of a pebble-bed reactor can be observed from its kinetic parameters. Proper modeling for calculating the reactor kinetic is also a concern for safe operation during normal and transient conditions.

NEUTRON DEPTH PROFILE CALCULATIONS USING ARTIFICIAL NEURAL NETWORKS [PDF]
EPJ Web of Conferences, 2021 Neutron depth profiling (NDP) is a non-destructive technique used for identifying the concentration of impurity isotopes below the sample surface. NDP is carried out by detection of the emitted charged particles resulting from bombarding the sample with ...

Study on kinetic parameters of pebble bed reactor with TRISO duplex fuel [PDF]
Nuclear Technology and Radiation Protection, 2023 Thorium, in this case, 232Th has a higher thermal neutron capture cross-section than 238U, which means that more fertile isotopes can be transmuted and could lead to higher fissile isotope 233U.

Neutron flux distribution in (Pb,Ta and W) target using accelerator of 18 MeV electron beam
Eurasian Journal of Physics and Functional Materials, 2021 The production of neutrons can be carried out with the bombardment of the nuclei of heavy atoms, with accelerated and energetic particles (generally electrons). The electron collides with the target nuclei, so, 20 to 30 neutrons are produced by a process
