3. NATURE OF PHYSICAL PROBLEM SOLVED

GRACE2 is a multigroup, multiregion, gamma-ray attenuation program to compute the total dose rate or heat generation rate from either a spherical or a cylindrical source. The source, which may be located in either the central region of the system or in a concentric shell region surrounding it, may be uniform, exponential, or have a polynomial variation in the radial direction. In the case of cylindrical geometry, it may also have a polynomial variation in the axial direction.
