Abstract

BISON is a nuclear fuel performance application built using the Multiphysics Object-Oriented Simulation Environment (MOOSE) finite element library. One of its major goals is to have a great amount of flexibility in how it is used, including in the types of fuel it can analyze, the geometry of the fuel being modeled, the modeling approach employed, and the dimensionality and size of the models. Fuel forms that can be modeled include standard light water reactor fuel, emerging light water reactor fuels, tri-structural isotropic fuel particles, and metallic fuels. BISON is a platform for research in nuclear fuel performance modeling while simultaneously serving as a tool for the analysis of nuclear fuel designs. Recent research in BISON includes techniques such as the extended finite element method for fuel cracking, exploration of high-burnup light water reactor fuel behavior, swelling behavior of metallic fuels, and central void formation in mixed-oxide fuel. BISON includes integrated documentation for each of its capabilities, follows rigorous software quality assurance procedures, and has a growing set of rigorous verification and validation tests.

摘要

BISON 是使用多物理场面向对象仿真环境 (MOOSE) 有限元库构建的核燃料性能应用程序。其主要目标之一是在如何使用方面具有很大的灵活性，包括可以分析的燃料类型、正在建模的燃料的几何形状、采用的建模方法以及模型的维度和大小. 可以建模的燃料形式包括标准轻水反应堆燃料、新兴轻水反应堆燃料、三结构各向同性燃料颗粒和金属燃料。BISON 是一个核燃料性能建模研究平台，同时也是核燃料设计分析的工具。BISON 最近的研究包括诸如燃料裂解的扩展有限元方法、探索高燃耗轻水反应堆燃料行为、金属燃料的膨胀行为和混合氧化物燃料中的中心空隙形成。BISON 包括其每项功能的集成文档，遵循严格的软件质量保证程序，并拥有越来越多的严格验证和验证测试。
