月球^3He资源开发的经济,技术可行性研究

TECHNIC AND ECONOMIC VIABILITY STUDY ON EXPLOITATION OF LUNAR 3He RESOURCE

从能量学的角度对开采月球３＿Ｈｅ资源作为Ｄ－３＿Ｈｅ聚变燃料的经济技术可行性进行了研究。拟分如下部分：太阳风的参数分析与月球表层土中的３＿Ｈｅ贮量估算；月球Ｈｅ的开采成本估算；月球白天就地真空加热抽取Ｈｅ的成本估算；月球夜晚就地低温分离同位素３＿Ｈｅ／４＿Ｈｅ的成本计算；液态３＿Ｈｅ从月球运回地球的成本估算；以月球运回的３＿Ｈｅ作为Ｄ－３＿Ｈｅ聚变燃料的能量偿还比计算。最后与地球上开采２３５＿Ｕ和煤发电的能量偿还比对照，给出Ｄ－３＿Ｈｅ与Ｄ－Ｔ燃料聚变能单位电价的比较。

From the energetics point of view,the technic and economic viabilty study on exploitation oflunar 3 He for fuelling the fusion reactor burning D-3He has been carried out.This study is di-vided into the following sections:analysis of solar wind parameters and estimation of potentialquantity 3 He in the lunar regolith,the cost evaluation of mining He of lunar soil;the energy costcalculation of He extraction by vacuum heating degassing during lunar day,the cost calculation ofcryogenic isotopic seperation 3He/ 4He during the lunar night,the energy cost for earth / moontransportation of liquid 3He,the energy payback calculation of fusion power burning 3He based lu-nar source,and finally the comparison of the energy multiplication with that for 253U productionof nuclear fuel and for coal mining. The comparisons of cost of electricity between D-3He and D-T fuel cycle for different reactor types have been discussed.
