Variational procedures for neutron and photon transport calculations in CTR blanket studies are considered. The procedures can be readily implemented to yield accurate results in an efficient manner and will be especially useful in performing sensitivity studies and survey calculations. They are applicable to multidimensional problems and to the time-dependent, as well as the steady-state, case. The use of the dual-space approach for certain sensitivity studies is also considered. Numerical results are presented to demonstrate the efficacy of the procedures discussed.
