Variance Reduction and Noise Source Sampling Techniques for Monte Carlo Simulations of Neutron Noise Induced by Mechanical Vibrations
Hunter Belanger, Davide Mancusi, Amélie Rouchon +1
Neutron noise in nuclear power reactors refers to the small fluctuations around the average neutron flux at steady state resulting from time-dependent perturbations inside the core…
Unbiasedness and Optimization of Regional Weight Cancellation
Hunter Belanger, Davide Mancusi, Andrea Zoia
The Monte Carlo method is often used to simulate systems which can be modeled by random walks. In order to calculate observables, in many implementations the "walkers" carry a stat…
Space and time correlations for diffusion models with prompt and delayed birth-and-death events
Théophile Bonnet, Davide Mancusi, Andrea Zoia
Understanding the statistical properties of a collection of individuals subject to random displacements and birth-and-death events is key to several applications in physics and lif…
