ARMP-02 documentation: Part 2, Chapter 5, EPRI-PRESS computer code manual: Volume 5, Guidelines

EPRI-PRESS is a computer program that automates the ARMP PWR calculational path and file structure so as to generate a data base for nodal static and transient calculations. The CELL-2, NUPUNCHER-2, APLB, GAD, and PDQ7E V2 modules, which previously functioned as stand-alone codes, are combined into a single application which generates cross sections and other data for use in a variety of nodal simulator codes; SIMULATE-E, NODE-P2 and ARROTTA. In addition, the cross sections so generated can be input to stand-alone PDQ7E calculations. Based on internal procedures, the CELL-2 module generates cross sections and other data for normal fuel pins, non-fuel regions, lumped burnable boron poison rods, and gadolinia-fuel pins. ''Generic'' control-rod cross sections for a variety of PWR assembly designs are stored internally and can be used if the user so chooses. The NUPUNCHER-2, APLB, and GAD modules process the data from CELL-2 into input for the PDQ7E V2 module, performing transport-to-diffusion parameterizations where necessary. EPRI-PRESS contains case lists for so-called ''one-temperature,'' ''two-temperature,'' and ''three-temperature'' models, and it will execute cases for whichever one of these models the user specifies. EPRI-PRESS builds input, executes all the specified cases, manages all data files, and produces a binary integral file which can be processed by the NORGE-P linkage code into input for either SIMULATE-E or NODE-P2. By doing so, it dramatically reduces the amount of effort and time required to perform these functions. It also simplifies traceability through the reduction of input and the use of automated data management. 8 refs., 11 figs
