RANKERN assists users with radiation transport problems in shield design, dosimetry and industrial applications.
The RANKERN code provides a rapid method for the design and assessment of gamma-ray shielding and dosimetry. RANKERN is suitable for determining dose-rates through shield materials, in ducts and labyrinths and from skyshine and has a wide-range of applications within the nuclear power industry and other market sectors.
RANKERN utilises the point-kernel technique coupled with build-up factors to correct the uncollided flux for the contribution due to scattering. The code uses a powerful and flexible threedimensional geometry modelling package to enable even complicated geometry systems to be described with minimum effort. RANKERN can also model any number of source bodies with different shapes, dimensions, orientations and spectra, within a single calculation. The integration of the point-kernel over the spatial distribution of the source is carried out using a stochastic integration method, which employs an automatic technique for adjusting the source importance function. Another benefit is RANKERN's ability to treat penetration paths involving multiple flight scatter or reflection events.
The code has a series of self-contained libraries; these include: a gamma-ray cross section data library for all elements, a set of cross section data for standard materials, libraries of Taylor form polynomial build-up factors and ANS643 build-up factors for common materials, an albedo data library and 22 and 180 energy group activation and fission product gamma-ray source libraries.
RANKERN has been successfully applied to such problems as:
RANKERN is supported by Visual Workshop, which means that checking for geometry errors is easy.
RANKERN is available for both Windows and Linux
