Monte Carlo Capabilities of the SCALE Code System

Abstract

SCALE is a widely used suite of tools for nuclear systems modeling and simulation that provides comprehensive, verified and validated, user-friendly capabilities for criticality safety, reactor physics, radiation shielding, and sensitivity and uncertainty analysis. For more than 30 years, regulators, licensees, and research institutions around the world have used SCALE for nuclear safety analysis and design. SCALE provides a ''plug-and-play'' framework that includes three deterministic and three Monte Carlo radiation transport solvers that can be selected based on the desired solution, including hybrid deterministic/ Monte Carlo simulations. SCALE includes the latest nuclear data libraries for continuous-energy and multigroup radiation transport as well as activation, depletion, and decay calculations. SCALE's graphical user interfaces assist with accurate system modeling, visualization, and convenient access to desired results. SCALE 6.2 will provide several new capabilities and significant improvements in many existing features, especially with expanded continuous-energy Monte Carlo capabilities for criticality safety, shielding, depletion, and sensitivity and uncertainty analysis. An overview of the Monte Carlo capabilities of SCALE is provided here, with emphasis on new features for SCALE 6.2.

NEAMS Workbench and Bison Fuel Performance Remote Application Configuration

“…This is done through the NEAMS Workbench runtime environment (RTE). Each application (BISON [4], ARC [6], MOOSE-Apps [7], Dakota [8], SCALE [9], CTFFuel [10], etc.) that is integrated into the NEAMS Workbench receives an RTE to assist the user and the NEAMS Workbench in managing the execution of the application on both local and remote machines.…”

A better hash method for high-fidelity Monte Carlo simulations on nuclear reactors

“…CSG is widely utilized by almost all Monte Carlo codes, including MCNP (Briesmeister, 1993), Serpent (Leppänen, 2013), OpenMC (Romano and Forget, 2013), SCALE 6.2/KENO (Rearden et al, 2014), MC21 (Sutton et al, 2007), JMCT (Deng et al, 2015), SuperMC (Wu et al, 2015) and RMC (Wang et al, 2015). The boundary representation method is widely used in CAD software such as SolidWorks and Pro/E.…”

Generación de librerías optimizadas con cuantificación de incertidumbres para cálculos realistas (BEPU) de reactores nucleares de agua ligera

“…KENO incluye técnicas de reducción de varianza como la ruleta rusa. En [103] se ofrece una amplia visión del código y sus características que no se exponen aquí por no ser el objeto de esta tesis.…”
