摘要
通过实验研究了在液态金属快中子增殖堆中，主壳顶盖下部遮热体的组成形式对遮热体工作性能的影响．本文提出了一个考虑到使用经济性的遮热体组成方案，供建造我国第一座快中子堆（ＣＥＦＲ）时参考．另外，本文对取消遮热体而完全用强制对流冷却系统对堆顶盖实施隔热保护的方案作了实验研究，给出了冷却流道平均Ｎｕｓｓｅｌｔ数计算公式，它对ＣＥＦＲ顶盖冷却系统的设计具有实用价值．
The effects of composition of insulation, i. e., renective multiplate thermal insulator,protecting the roof-slab of the vessel of the LMFBR on the heat transfer Performance has been studied experimentally for CEFR. A economical form of the thermal insulation is suggest for CEFR. In addition, the scheme without reflective thermal insulator which has only a forced convection cooling system has been studied experimentally and a formal to calculate the average Nusseltnumber of the flow channel, which is valuable for CEFR design, has been raised.
