乏燃料后处理玻璃固化产品干法贮存通风方式优化研究及仿真模拟分析

Research and CFD Analysis of the Ventilation System in Dry Interim Storage Building of Vitrification Plant for Dealing with Spent Fuel

本文介绍了高放发热体干法贮存的一般通风形式,采用隔热材料优化自然通风方式,并运用CFD技术对其进行模拟计算分析。研究发现采用隔热措施能有效降低发热体对混凝土结构的热影响,强化自然通风,达到节能和降低运行维护费用的效果。

This paper introduces the general ventilation system in dry Interim Storage Building（ISB） of the Vitrification Plant China for dealing with spent fuel. On this basis, using adiabatic material optimizes the natural convection and using CFD analyses the case. The research gets the result that using adiabatic material can reduce the temperature of concrete, enhance the effect of the natural convection, reduce energy consumption and maintenance expense.
