BOT3P: A Mesh Generation Software Package for the Transport Analysis Codes DORT, TORT, TWODANT, THREEDANT and MCNP

BOT3P consists of a set of standard FORTRAN 77 language programs that gives the users of the deterministic transport codes DORT and TORT some useful diagnostic tools to prepare and check the geometry of their input data files far both Cartesian and cylindrical geometries including graphical display modules. BOT3P produces at the same time the geometrical and material distribution data far the deterministic transport codes TWODANT and THREEDANT and, only in three-dimensional (3D) Cartesian geometry, far the Monte Carlo Transport Code MCNP. This makes it possible to compare directly for the same geometry the effects stemming from the use of different data libraries and solution approaches on transport analysis results. Through the use of BOT3P, radiation transport problems with complex 3D geometrical structures can be modelled easily, as a relatively small amount of engineer-time is required and refinement is achieved by changing few parameters. This tool is useful far solving very large challenging problems.
