    • A method including a combination of intermediate storage and reprocessing is utilized to process spent nuclear fuel (SNF) and thereby effect a disposition of that SNF within a period of 300 years. The method includes five or more years of pool water storage wherein ninety-nine percent (%) of the fission wastes energy decays. The waste material is then stored in an air convention storage facility, before processing to separate Cesium and Strontium from the waste is effected. This air convection cooling may be done in convection air-cooled concrete casks. During 50 years of convection air-cooled storage the energy contained in the waste material declines another one half %. Thereafter, at any point the SNF is processed to sufficiently separate 99.999% of the 97% of actinides (approximately 95% U238 uranium, 1% U235 uranium, and 1% Pu239 plutonium) from the 3% fission wastes. Again, it is only necessary to provide approximately 99.999% separation of the TRU's (transuranic waste) from the fps (fission products)—more specifically, sufficient separation so that the residual fps are contaminated with less than 100 nCi/g TRU's, as defined in the Class C regulations—10CFR61. The separated actinides and transuranics are thereafter utilized in the manufacture of MOX (mixed oxide) or fast burner reactor fuel pellets for future reactor fuel. The remaining fission wastes, containing Cesium and Strontium, are then placed into containers and subsequently put into dry storage for the remainder of around 300 years, where most of the remaining half % of its radiation energy material, i.e., Cesium and Strontium decays. Thereafter this fission waste is put into a low level Class-C nuclear waste repository, which may include leaving them in the intermediate storage facility that is also designed to accommodate and dispose Class C waste.
    • 使用包括中间储存和再加工的组合的方法来处理乏燃料(SNF),从而在300年的时间内对该SNF的处置进行处理。 该方法包括五年或五年以上的池水储存,其中百分之九十九(%)的裂变废物能量衰减。 然后在将废弃物分离出铯和锶的处理之前将废料储存在空气会议存储设备中。 这种空气对流冷却可以在对流风冷混凝土桶中进行。 在50年的对流空冷存储中,废物中所含的能量下降了另外的一半。 此后,在任何时候处理SNF以从3%裂变废物中充分分离97%的锕系元素(约95%U238铀,1%U235铀和1%Pu239钚)的99.999%。 再次,仅需要从fps(裂变产物)提供大约99.999%的TRU(超铀废物)分离 - 更具体地说是足够的分离,使得剩余的fps被限定在少于100nCi / g TRU的范围内 在C级法规10CFR61。 此后分离的锕系元素和超铀元素用于制造未来反应堆燃料的MOX(混合氧化物)或快速燃烧器反应堆燃料颗粒。 剩余的含有铯和锶的裂变废物然后放置在容器中,随后放置在干燥储存中,剩余时间约为300年,其余的半数辐射能量材料的大部分即铯和锶都会衰变。 此后,这种裂变废物被放入一个低级别的C类核废料处理库中,这可能包括将它们留在中间储存设施中,该设施也被设计为容纳和处置C类废物。

    • An internal combustion engine, synthesizing CO and H.sub.2 fuels from methanol in a first synthesizer, and also synthesizing H.sub.2 fuel from CO and water in a second synthesizer, thus upgrading a technically difficult to use fuel to a low polluting, easily usable fuel, by use of the energy from exhaust gas waste heat thus improving the fuel heating value by 20%; the engine fuel system also having an alternate energy source for synthesizing the fuel, the engine also having an additional alternate fuel source for engine starting and operation when the synthesized fuel reservoir is low and electrical battery energy is limited thus allowing time for the heat exchanger synthesizers to warm up to produce CO and H.sub.2 fuel, which is especially required during cold operating seasons.
