Abstract

An adjustable description of the temperature distribution in the nuclear fuel elements is evaluated to the prediction of the lifetime behavior of these components. The impact of the fuel and coolant temperature on the neutron reaction rates provides an incentive for accurate modelling of the temperature behavior under transient as well as steady-state operating conditions. This paper is to focus on the steady-state temperature field in the fuel elements. Many of the principles applied are also useful for describing the temperature field in the structure component.
燃烧核燃料元件的热模拟
对核燃料元件中温度分布的可调整描述进行了评估,以预测这些元件的寿命行为。燃料和冷却剂温度对中子反应速率的影响促使我们对瞬态和稳态运行条件下的温度行为进行精确建模。本文将重点讨论燃料元件的稳态温度场。所应用的许多原理也可用于描述结构部件中的温度场。
