3. NATURE OF PHYSICAL PROBLEM SOLVED
The Monte Carlo code MERCURE 4 computes in a three dimensional heterogeneous geometry heating and gamma dose rate, and by the point wise kernel attenuation in straight line, the fast fluxes. Tabulated accumulation factors give the contribution of the scattered gamma rays.
The program calculates accumulation factors for mixtures; for multi- layer media Kitazume formulation is used.
GAMLEG/A produces the multigroup photonic library. The sources can be represented in different geometries. For each geometry, the program works with a homogeneous lattice with plane and quadrical boundaries.
