The MVP general-purpose continuous-energy Monte Carlo code for neutron and photon transport calculation, together with its multigroup version (GMVP), were designed for vector supercomputers, and then a parallel processing capability was added. Features and capabilities include the following: vectorization and parallelization; combinatorial geometry with multiple-lattice capability and the statistical geometry model; the probability table method for unresolved resonance; realistic calculations of power reactors at arbitrary temperature; depletion calculations; perturbation calculations for an eigenvalue (k{sub eff}) problem; and useful tallies for improvement of the multigroup method such as effective macroscopic and/or microscopic cross sections, etc. Recently, the development work has concentrated on capabilities of applying the code to accelerator-driven subcritical reactors. For this purpose, functions for the high-energy particle transport capability and simulations of the Feynman -{alpha} experiment (noise analysis) are being added, and these are discussed in the rest of the paper.
