Interest is in developing neutronic and thermal-hydraulic computer programs that execute efficiently on advanced engineering work stations. Engineering work stations are characterized by a 32-bit arithmetic processor, graphics capabilities, and networking capabilities. These attributes allow an engineer to solve substantive problems in a graphical interactive environment with shared resources available via networking. An advanced engineering work station is further characterized as having computational capability comparable to a mainframe, achieved via a parallel computer architecture obtained by both multi-central processing units (CPUs) and vector pipelines. In this paper, the authors present timing studies completed on an engineering work station, and then extrapolate performance on an advanced engineering work station using results from a supercomputer with parallel architecture. In this paper, the authors report on two codes, a neutronic code and a LWR system's thermal-hydraulic code. The neutronic code solves the two-group, two-dimensional (x-y) neutron diffusion equations using the finite difference method. The system's thermal-hydraulic codes solves the mixture drift-flux representation of the tube-stream form of the Navier-Stokes equations (four-equation model).
