We show that the cornerstone of QM – Born's rule – can be obtained from detection theory (SDT) for subquantum (classical) random field. The basic assumption of SDT is that the probability of detection of a field (=signal) is proportional to the power of this field (its L 2-norm). Our approach has some similarities with the semi-classical approach to the electromagnetic field. However, formalism...

The aim of this paper is to propose a new approach for optimizing the position of fuel assemblies in a nuclear reactor core. This is a control problem for the neutronic diffusion equation where the control acts on the coefficients of the equation. The goal is to minimize the power peak (i.e. the neutron flux must be as spatially uniform as possible) and maximize the reactivity (i.e. the efficie...

Neutronic analysis on the Molten Salt Reactor FUJI-12 using fissile material 235U in LiF-BeF2-UF4 has been carried out. The problem faced use of thorium-based fuel is that amount 233U small and not available nature. was produced through 232Th breeding at a cost $46 million/kg. That very high price when compared to enrichment, which only $100/kg. MSR used this study generation IV reactor with mi...

This work presents the results for a coupled neutronic-thermalhydraulic-thermomechanic pin-level depletion calculation of PWR fuel assembly using Serpent2-SUBCHANFLOW-TRANSURANUS. tool is based on semi-implicit scheme with pin-by-pin feedback, mesh-based field exchange and an object-oriented software design. The impact including fuel-performance capabilities analyzed, focus high-burnup effects....
