Abstract A new design integrating heat-pipes into a nuclear cooling system is presented. The heat-pipes are presented as the primary mode of heat transfer. Analyzing the prevailing limits to determine suitability for predicting the performance of the heat-pipe concept. When the limits are determined for the design integration, steady-state behavior needs to be quantified. A model that accounts for 3D behavior is evaluated for use. Using the limits to evaluate the design integration, with sodium, the operating regime would still remain below the predicted limits. With potassium the operating regime would exceed the capillary limit. This is caused by the increase in pressure drop. With the 3D model, a validation shows that conduction can give very good results for both transient and steady-state behavior for sodium. It shows that water has poor transient prediction but accurately predicts the steady-state behavior. Both solutions were close to the reported experimental results for steady-state.

先进核热管系统的新型设计集成

摘要 提出了一种将热管集成到核冷却系统中的新设计。热管被认为是主要的传热方式。分析普遍的限制，以确定预测热管概念性能的适用性。当设计集成的限制被确定时，稳态行为需要被量化。对考虑 3D 行为的模型进行评估以供使用。使用限制来评估设计集成，使用钠，操作制度仍将保持低于预测的限制。使用钾时，操作状态将超过毛细管极限。这是由压降的增加引起的。使用 3D 模型，验证表明传导可以为钠的瞬态和稳态行为提供非常好的结果。它表明水具有较差的瞬态预测，但准确地预测了稳态行为。两种解决方案都接近于报道的稳态实验结果。
