Direct Doppler broadening in Monte Carlo simulations using the multipole representation [PDF]
, 2013 A new approach for direct Doppler broadening of nuclear data in Monte Carlo simulations is proposed based on the multipole representation. The multipole representation transforms resonance parameters into a set of poles and residues only some of which ...

Improved cache performance in Monte Carlo transport calculations using energy banding [PDF]
, 2018 We present an energy banding algorithm for Monte Carlo (MC) neutral particle transport simulations which depend on large cross section lookup tables. In MC codes, read-only cross section data tables are accessed frequently, exhibit poor locality, and are

Test Results of Variance Reduction Techniques Applied to Deep Penetration Problem
Глобальная ядерная безопасность, 2022 Nowadays, there is a problem of a lack of computer power to conduct high-precision reactor analysis. There are several factors that increase the excessive computational load and make it difficult to calculate nuclear reactor full-scale models using Monte

Water Resources Research, Volume 55, Issue 12, Page 10796-10812, December 2019., 2019 Abstract Cosmic‐ray neutron sensing (CRNS) is a promising non‐invasive technique to estimate snow water equivalent (SWE) over large areas. In contrast to preliminary studies focusing on shallow snow conditions (SWE 130 mm), more recently the method was shown experimentally to be sensitive also to deeper snowpacks providing the basis for its use at ...

Integrating ytopt and libEnsemble to autotune OpenMC
The International Journal of High Performance Computing ApplicationsYtopt is a Python machine-learning-based autotuning software package developed within the ECP PROTEAS-TUNE project. The ytopt software adopts an asynchronous search framework that consists of sampling a small number of input parameter configurations and progressively fitting a surrogate model over the input-output space until exhausting the user ...
