Space-time flux synthesis methods for the approximate solution of the time-dependent Boltzmann neutron transport equation are formulated in this report. The variational and the Galerkin techniques are used. The space-dependent part of the solution is obtained with the DTF-II program — an Sn-type solution of the transport equation. Temperature feedback effects are considered in the formulation. The formulation presented here is adapted to the description of rapid transients following a large reactivity input, but the method can be easily modified to cover other reactor problems where a space-time flux description is necessary. It should be useful whenever the situation requires the transport approximation for the description of the neutron flux.
