BOT3P Version 1.0 was originally conceived as a set of standard FORTRAN 77 language programs in order to give the users of the DORT and TORT deterministic transport codes some useful diagnostic tools to prepare and check their input data files. Later versions extended the possibility to produce the geometrical, material distribution and fixed neutron source data to other deterministic transport codes such as TWODANT/THREEDANT of the DANTSYS system, PA.RTISN and, potentially, to any transport code through BOT3P binary output files that can be easily interfaced (see, for example, the case of the Russian two-dimensional (2D) and three-dimensional (3D) discrete ordinates neutron, photon and charged particle transport codes KASKAD-S-2.5 and KATRIN-2.O). BOT3P Version 5.1 contains important additions specifically addressed to radiation transport analysis for medical applications. The new module CATSM lets users reduce the geometrical size of problems related to elaborated (already interpreted by physicians or by proper software) computerized (axial) tomography (CT/CAT) scans without or with small detail loss with respect to the original voxelized geometry. This permits to have problem sizes that can be more easily managed by transport codes. CATSM can automatically generate tetrahedron mesh grids also, starting from the input voxelized geometry, even though the implemented algorithm is still rather rough and to be improved in the future. BOT3P-5.l contains new graphics capabilities that enable users to visualize tetrahedron mesh grids in 3D and 2D cuts. BOT3P was developed on a DIGITAL UNIX ALPHA 500/333 Workstation and successfully used not only in some complex neutron shielding and criticality benchmarks but also in power reactor applications (Westinghouse AP1000 internals heating rate distribution calculations by Ansaldo Nucleare (Italy)). BOT3P was also tested on Red Hat Linux 7.1 and is designed to run on most UNIX platforms. All BOT3P versions are publicly available from OECD/NEA Data Bank (F) and most of them are also distributed by ORNL/RSICC (USA).
