, 2021 There seems to exist significant similarities between a reactor system and a supply chain from collection to delivery. In the reactor case, neutrons are continuously produced and absorbed in nuclear fuel. In a supply system case, items are continuously collected and continuously delivered to destinations.

Science and Technology of Nuclear Installations, 2020 For nuclear reactor physics, uncertainties in the multigroup cross sections inevitably exist, and these uncertainties are considered as the most significant uncertainty source. Based on the home-developed 3D high-fidelity neutron transport code HNET, the

Parareal in time 3D numerical solver for the LWR Benchmark neutron diffusion transient model [PDF]
, 2014 We present a parareal in time algorithm for the simulation of neutron diffusion transient model. The method is made efficient by means of a coarse solver defined with large time steps and steady control rods model.

Development of a Spatial Domain Decomposition Scheme for Monte Carlo Neutron Transport
Volume 3: Nuclear Fuel and Material, Reactor Physics, and Transport Theory, 2018 The computing power available nowadays to the average Monte-Carlo-code user is sufficient to perform large-scale neutron transport simulations, such as full-core burnup or high-fidelity multiphysics.

A Novel Adjoint-Based Reduced-Order Model for Depletion Calculations in Nuclear Reactor Physics
EnergiesThe licensing of new reactors implies the use of verified and validated neutronic codes. Numerical validation can rely on sensitivity and uncertainty studies, but they require repeated execution of time-consuming neutron flux and depletion calculations ...

Improving PWR core simulations by Monte Carlo uncertainty analysis and Bayesian inference
, 2016 A Monte Carlo-based Bayesian inference model is applied to the prediction of reactor operation parameters of a PWR nuclear power plant. In this non-perturbative framework, high-dimensional covariance information describing the uncertainty of microscopic ...
