Title: MCDAN: a Monte Carlo computer code for calculating the Dancoff correction factor for spheres and rods

Abstract

MCDAN is a computer code that uses Monte Carlo techniques to calculate the Dancoff correction factor for arrays of spheres or rods. Neutrons are started from the surface of the sphere (rod) and tracked until they intersect another sphere (rod). The histories of a number of neutrons are statistically combined to give a value for the Dancoff correction factor. MCDAN was written as a tool to verify the accuracy of an expression for the Dancoff correction factor used in a study of the reactivity effect of fuel particles in uranium--water mixtures. The accuracy of MCDAN has been verified by comparison with tabulated data for systems of two spheres (rods).

  • Resonance integral calculations for a reactor lattice require the use of the Dancoff factor. In the past, tables and approximate expressions have been used to obtain this value. In order to reduce the uncertainty in the use of approximations and to avoid the inconvenience of tables, a series of computer programs has been written to calculate the Dancoff factor. Three computer programs have been prepared, one each for infinitely long cylinders, spheres, and infinite slabs. The program for cylinders includes corrections for the effect of partial shadowing of a rod by adjacent rods and for the effect of clad surroundingmore » the rods. The effect of clad is also considered in the slab program. Although these corrections can be applied to sphere arrays, they have not been included in the sphere program. It was felt that the infrequent use of spherical arrays did not justify the additional time and effort to include these corrections.« less

    The Monte Carlo computer code, PHOEL-3, which is described here, replaces an earlier code, PHOEL-2, for generating the initial energies of electrons and positrons produced in water by irradiation with photons having an arbitrary energy spectrum up to 1 GeV. The code handles input photons individually on the basis of the energy-dependent cross sections for the physical processes treated, which are the photoelectric effect, Compton scattering, and pair and triplet production. Options exist for (1) following each photon through successive Compton scattering events until it disappears by photoelectric absorption or pair production, (2) allowing at most only a single Compton-scatteringmore » event per input photon, and (3) turning the photoelectric effect on or off. If energetically possible, it is assumed that a photoelectron originates in the oxygen K shell; otherwise, it originates in the L shell. An Auger electron of energy 0.508 keV is assumed to be emitted following the creation of a K vacancy. The code can calculate both the relative number of electrons and positrons at various initial energies and the absolute number per unit photon fluence, which can be used directly to compute kerma. For comparison with other work, detailed calculations made with PHOEL-3 give results that agree with the work of Cormack and Johns for photon energies of up to 25 MeV. The numerical data used in PHOEL-3, the mathematical treatment of the calculation, and the operation of the code are described in this manual. PHOEL-3 can be obtained from the Radiation Shielding Information Center at Oak Ridge National Laboratory. The present code differs from the earlier PHOEL-2 by (1) including pair and triplet production, (2) calculating the absolute number of electrons and positrons in addition to the relative number, and (3) extending the photon energy range from 2 MeV up to 1 GeV.« less

    A Monte Carlo computer code, PHOEL-2, is described for generating the energies of photoelectrons and Compton electrons in water irradiated uniformly by photons having an arbitrary energy spectrum. The code treats input photons individually on the basis of the energy-dependent cross sections for Compton scattering and for the photoelectric effect. Options exist for following each photon through successive Compton scattering events until it disappears by photoelectric absorption or allowing at most only a single Compton scattering event per input photon. The photoelectric effect can be turned on or off with either option. If energetically possible, the photoelectron is assumed tomore » come from the oxygen K shell; otherwise, it originates in the L shell. An Auger electron of energy 0.508 keV is assumed to be emitted following the creation of a K vacancy. The basic numerical data used in PHOEL-2, their mathematical treatment, and the operation of the code are described. Detailed comparisons made with work for /sup 60/Co, and monoenergetic x rays confirm the numerical validity of results obtained with the code. Some of the data of Cormack and Johns are extended by including successive Compton scatterings for the same photon and by including the photoelectric effect and Auger electrons. PHOEL-2 can be obtained from the Radiation Shielding Information Center at Oak Ridge National Laboratory. The new version differs from the old by employing a more realistic handling of the photoelectric cross section as a function of energy, compiling electron spectra instead of storing the energies of every electron produced, eliminating some former input restrictions, and using a different random number generator. PHOEL-2 does not treat pair production, which should be included for water at photon energies above about 2000 keV. 5 figures, 4 tables.« less
