3. DESCRIPTION OF PROGRAM OR FUNCTION

KENO-4(RG) is an extension of KENO-4 to allow random geometry (RG) descriptions of materials in the geometry model. This version can be used in the case where the geometry of materials is too complex, such as in the case of dumped  Raschig rings, for description using ordinary mathematical models. KENO-4 solves nuclear criticality eigenvalue problems. The results calculated by KENO-4 include k-effective, lifetime and generation time, energy-dependent leakages and absorptions, energy- and region- dependent fluxes and region-dependent fission densities. Criticality searches can be made on unit dimensions or on the number of units in an array.

4. METHOD OF SOLUTION

KENO-IV(RG) solves the Boltzmann neutron transport equation using Monte Carlo methods. In the random geometry model, the material thickness of solution or ring along the neutron  path is randomly chosen from its predetermined material thickness distribution function, simulating the random orientation or Raschig  rings in the solution. These distributions have been obtained experimentally and verified by "mathematical tests".

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The number of solution thicknesses and dumped material thicknesses are each limited to 100.

6. TYPICAL RUNNING TIME

Running times are highly problem dependent on the complexity of the geometry, the number of energy groups, and the type of materials in the problem.
