由于本身的特性及社会大众的感观,核电厂的安全必需不断的精进,并视各种不正常的运作状况做出改进。福岛核灾之后,未来核电厂除了会针对复合性灾难做出评估外,用过燃料的贮存也是改进的重点。放置于乏燃料池中的乏燃料在电厂全黑时无法移热,而干式贮存系统则能在室温下完全移除燃料的衰变热。为完成干式贮存系统的建置,吾人引进计算流体力学软件-FLUENT来对系统的热传导状况进行分析及认证。FLUENT计算能力卓越,但强大的功能也附带了繁琐的操作,本研究之目地在于将FLUENT其中一部份计算过程以Visual Basic(VB)另外独立写成一窗口化操作接口软件,将干贮系统热流分析中常需计算之组件预先模块化,以期进行热流分析时,得以加速整体工作之进展。

The safety of Nuclear Power Plant needs to keep developing because of its feature. People don’t want to see any accident even that is just a simple error. So, the SOP of Nuclear Power Plant is revised every time when there’s in normal situation of operation. After the Fukushima Disaster, Complex Disasters and Spent Fuel Storage are the two points that Nuclear Engineering should notice. Power plants put spent fuel into spent fuel pool before we have a better way to deal with spent fuel. In Station Black Out situation, spent fuel pool can’t remove decay heat. That’s why 4th and 5th units of Fukushima 1st Plant damaged in disaster. Spent Fuel Dry Storage System can avoid this kind of accident because it can remove decay heat completely by natural circulation. To build the system, we need to analyze the heat transfer condition, so INER introduced CFD-FLUENT to do the simulation. FLUENT is a CFD program with accurate calculation ability, but it always takes long time to get the calculating results and also some other disadvantages. To save time of simulations, we want to conduct a new program which has modularized some computation processes. It can also improve quality of simulation.
