3. DESCRIPTION OF PROGRAM OR FUNCTION

MARMER is a point-kernel shielding code which can be used to calculate the dose rate, energy absorption rate, energy flux or gamma-ray flux due to several sources at any point in a complex geometry. The geometry is described by the MARS geometry system which makes use of Combinatorial Geometry and an array repeating feature. Source spectra may be defined in several ways including an option to read a binary file containing nuclide concentrations, which has been calculated by ORIGEN-S. Therefore, MARMER makes use of a nuclide data library containing half life times, decay energies and gamma yields for over 1000 nuclides. To facilitate the use of ORIGEN-S, a preprocessor named PREORI is included for simple irradiation and decay problems. The spatial description of the source may be done in cartesian, cylindrical and spherical coordinates and the source strength as a function of the distance along the coordinate axes may be done in many different ways. Several sources with different spectra may be treated simultaneously. As many calculational points as needed may be defined.

4. METHOD OF SOLUTION

The source volume is divided into volume- elements and the source energy distribution is divided into energy groups. The unscattered gamma-ray flux is calculated by an exponential attenuation kernel, which is integrated over all source volume-elements and all energy group by use of a Monte Carlo integration method. The flux is then converted to the requested detector response by use of conversion factors, which are read from a binary file. Scattered gamma-rays are accounted for by buildup factors, which are tabulated in another binary file containing dose rate equivalent and energy absorption buildup factors. Buildup factors for each shield are calculated by interpolating for the effective atomic number of the shield. For multilayered shields the buildup factor of one shield or the methods of Kitazume or Broder may be used. Although all necessary data is read from binary files, attenuation coefficients, detector response functions and buildup factors may be given in the input too.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

MARMER can be subdivided into two parts: the MARS geometry system, where all geometric data is stored and handled, and the real shielding code, which is partly based on the MERCURE-IV shielding code. Both parts make use of flexible array dimensioning, so in principal there is no restriction on the complexity of the problem. There is, however, one exception: no more than 50 materials may be defined.

6. TYPICAL RUNNING TIME

CPU times for MARMER depend very much on the problem treated, especially on the complexity of the geometry, and can vary from a few seconds to tens of minutes per dose point on a

VAX 8350.

NEA-1307/01

NEA-DB executed the different modules of this package on a VAX 8810 computer. The following CPU times were required to run the specified test cases. BINBCD: 7.4s (buildup factor); 3.8s (gamma data); 23.9 s (nuclide data). MARMER: 5.2 s (case 1); 344 scase 2); PICTURE: 2.6 s (case 1); PREORI: 1.0 s (vase 1); ORIGENS: 9.7 s (case 1).

NEA-1307/02

The test case of MARMER executed at NEA-DB on a 66-MHz PC/80486 in 20.7 seconds of elapsed time. The execution of BINBCD.EXE to produce the binary version of the three libaries MARISO (nuclide data), MARBUP (buildup factor data), and MARGAM (gamma data) takes, respectively, 17.7, 8.2; and 3.0 seconds of elapsed time.[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

MARMER has several options not available in other point-kernel shielding codes: the possibility to use nuclide concentrations calculated by ORIGEN-S to define source spectra, the flexible energy structure by use of "fine" energy groups which can be collapsed to "broad" groups depending on the problem under consideration, anisotropic sources (cos**p or arbritrary defined by points), which can be used to calculate the unscattered component of thes treaming radiation through ducts and gaps.

8. RELATED AND AUXILIARY PROGRAMS

ORIGEN-S with six data libraries can be used to calculate nuclide concentrations, PREORI can be used as a preprocessor to ORIGEN-S, BINBCD is used to convert the three MARMER libraries from ASCII or BCD to binary form and vice-versa, the MARS geometry package is used to describe the geometry, PICTURE may be used to print two-dimensional slices of geometry and JUNEBUG may be used to plot three-dimensional pictures of geometry.
