BOT3P Version 3.0: The ENEA Bologna Pre-Processors of the DORT, TORT, TWODANT, THREEDANT and MCNP Transport Codes and Post-Processors of DORT and TORT

BOT3P is a set of standard FORTRAN 77 language program developed at the ENEA-Bologna Nuclear Data Centre. BOT3P Version 1.0 was originally conceived to give the users of the DORT and TORT deterministic transport codes some useful diagnostic tools to prepare and check their input data files. BOT3P Version 2.0 involved some important additions in the input geometrical model description and extended the possibility to produce the geometrical, material distribution and fixed neutron source data to the deterministic transport codes TWODANT and THREEDANT of the DANTSYS system too, starting from the same input to BOT3P. BOT3P Version 3.0 can generate a geometrical input for the MCNP Monte Carlo transport code also, when users require X-Y-Z TORT/THREEDANT mesh grids to be generated. Moreover, it lets users specify areas/volumes of the model where the zone/material distribution may be defined not only by a combinatorial geometry but also by an external source, such as, for example, one or more external DORT/TORT input files of files derived from computerized tomography (C.T.) scans (for three dimensional (3D) applications only). For example, users can easily insert a tree-dimensional material zone matrix originated from CT scans into a facility model or include one or more partial volumes with the material mixture distribution defined in one or more external TORT input files in a new 3D model for transport analysis. BOT 3P was developed on a DIGITAL UNIX ALPHA 500/333 Workstation and successfully used in some complex neutron shielding and criticality benchmarks. BOT3P was also tested on Red Hat Linux 7.1 and is designed to run on most UNIX platforms. All BOT3P versions are or will be publicly available from OECD/NEA Data Bank.
