This report describes the transformation of the NSWC Burn Model into a general purpose program which produces a simple set of information. This information can be transformed into a tabular database that can be used by any one, two, or three dimensional hydrocode which contains a reactive mixture scheme. The term, general purpose program, is used throughout this report to emphasis the fact that the computer program which produce the tabulated data set is separate from the hydrocode run which uses the tabulated data set. The basic equations which present the concepts of the NSWC Burn Model are solved explicitly by a general purpose program in a Lagrangian coordinate system. These equations and the solution method are described in Section 2. Relationships which prescribe the necessary parameters for a hydrocode computation are shown in Section 3. Section 4 presents some conclusions and direction of future work. The NSWC Burn Model assumes that a typical pore and binder in a high explosive can be modeled by a void region inside a sphere. Therefore, it is referred to as a hollow sphere model.
