| 摘 要： | 介绍输运燃耗耦合程序MCORGS的理论模型,利用MCORGS研究铀-水体积比对混合能源堆中子学性能的影响。研究表明,采用天然铀为裂变燃料,且铀-水比为2:1时,可实现较高的能量放大,保持氚自持,中子学性能可以维持100 a以上;采用压水堆乏燃料时,铀-水比的选择余地更大,能量放大和产氚能力提高,但燃料增殖能力下降。

| Abstract: | The theoretic model of MCORGS code,which is used in this paper to evaluate the effect of the volume ratio between uranium and water(VR) on a fusion-fission hybrid for energy production,is introduced.It is showed that at natural uranium case,the VR of 2:1 is preferred,since it can reach a comprise between energy multiplication and tritium breeding ratio,and the neutronics performance of the system can maintain more than 100 years.At the case of spent fuel from PWR,there are more room for selection of VR.Both energy multiplication and tritium breeding ratio will improve,however the fissile material breeding capacity will degrade. |
