WCSAR-TR-AR3-9107-1 A Review of Helium-3 Resources and Acquisition for Use as Fusion Fuel [Published in Fusion Technology, Special Issue on DHe3 Fusion, Vol. 21 (4) 2230-2253]
A combination of man-made and natural resources on earth could provide sufficient He fuel for the technological development of D-He fusion reactors. Helium exists in natural gas wells; however, at the present rate of natural gas usage this resource would provide < 5 kg/yr of He. The radioactive decay of H produced in fission production reactors could yield 110 kg of He by the year 2000 if it we...
متن کاملWCSAR-TR-AR3-9201-3 Apollo 11 Ilmenite Revisited [prepared for Space 92, The Third International Conference on Engineering, Construction, and Operations in Space, 31 May-4 June 1992, Denver CO]
Various investigations have shown (1) that lunar regoliths are extremely complex materials, (2) that ilmenite is a minor component (8 to 10%) of highTi regoliths, and (3) that most of the ilmenite is interlocked with other minerals or glass in regolith particles. A review of polished sections of Apollo regolith samples that I studied in 1970 in general confirms these findings. Beneficiation of ...

A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar soil is increased approximately 100fold by the introduction of an artificial hydrogen atmosphere at 1 atm pressure enclosed in an inflatable structure. The leakage rate of H2 through the soil is minimal because o...

A direct, high-resolution measurement from lunar orbit of the location of high concentrations of 3He in the lunar regolith is needed for the initiation of cost-effective mining operations on the moon. Gamma-ray spectroscopy has been successfully used to map the abundances and distributions of certain elements present in planetary regoliths. Helium-3 is unique among these elements since the gamm...
متن کاملWCSAR-TR-AR3-9201-5 Environmental Aspects of Lunar Helium-3 Mining [prepared for Space 92, The Third International Conference on Engineering, Construction, and Operations in Space, 31 May-4 June 1992, Denver CO]
Three potential detrimental effects of lunar 3He mining have been identified; visual changes, atmospheric contamination, and solid waste disposal. The removal of small craters (<20 m diameter) and the change in the albedo of the surface may cause a slight darkening of the regolith. However, it is not expected that this change will be visible from the Earth even with powerful telescopes. The rel...
