Improved closed-loop pyrochemical processes for the decomposition of water in which at least one reaction step in each process has a high energy requirement that may be expressed in standard Gibbs free energy change terms of more than 10 to 20 kcal/mole at 298.degree. K., .DELTA.G.sup.o.sub.f298. Such high energy steps are carried out in the central reaction chamber of a thermonuclear reactor wherein the energy of intense shock waves, hereinafter called the blast waves, caused by a pellet-by-pellet intermittent thermonuclear reaction provides an automatic drive for the process step kinetics. During the radial outward propagation of the blast wave reaction materials within the chamber are heated and compressed within the blast wave and entrained behind the blast wave. The product density immediately behind the blast wave remains directly proportional to the ambient density ahead of the wave. Chemical reaction thus takes place dynamically in transit at very high temperatures and pressures in a manner that permits the chemical reaction to absorb energy, and without confinement in a vessel requiring high pressure and high temperatures chronically. In this way, the process step having a high energy change requirement is accomplished in one high-energy reaction step rather than in several low and intermediate reaction steps having an energy sum which equals the required total.
The pyrochemical process of decomposition of a chemical raw material which includes water or CO.sub.2 into at least one constituent element in a high energy process in a single thermal step comprising the step of introducing the chemicals into a central reactor chamber with a deuterium-tritium nuclear fuel pellet, irradiating the pellet to produce a deuterium-tritium nuclear reaction of which a fraction of the energy released appears in an expanding blast wave front over a small fraction of a second, chemically decomposing said chemicals in the high temperatures and high pressures introduced by said blast wave, driving the reaction elements wherein the step of removing the constituent element from the reaction chamber comprises opening a distributed valve(s) in said central reactor by said blast wave front to expel said element from said central chamber as a part of the kinetic drive action performed by said blast wave outwardly in the reactor chamber toward an enclosure wall by nuclear reaction, and removing the reaction products from said chamber thereby to produce said constituent element.
