Resumo: The LABIHS (Human-System Interfaces Laboratory) compact nuclear power plant (NPP) simulator is, since 2002, operating at the Nuclear Engineering Institute (IEN), Brazil. Due to the processing power required by the simulator software and the hardware available at the time, the simulator was developed under a PA-RISC architecture server (HPC3700), using the HP-UX operating system. All mathematical modeling components were written using the HP Fortran-77 programming language with a shared memory to exchange data from/to all simulator modules. In 2008, this hardware/software framework was discontinued, with customer support ceasing in 2013, what makes it difficult to maintain and expand. On the other hand, technological progress during this period enabled cheaper and more accessible computers, such as the PC (Personal Computer) architecture, to have enough processing power to run the simulator framework. It turns out that the PA-RISC computer architecture is incompatible with the PC one. Thus, our work group has been working, for some years, to port the simulator to the PC architecture. Part of this effort includes completely rebuilding all the MMI (Man- Machine Interface) using modern software tools and programming languages which are compatible with the PC architecture. In this work, we present two important steps for the NPP simulator migration from the obsolete architecture to the PC one. Firstly, we provide a new inter-process communication library which allows the data exchange between the NPP simulator currently running at the old PA-RISC architecture and other software running on modern PCs. This step is important because it allows us to work on the new Graphical Interface while the older NPP simulator is still operating. Secondly, we present the all-new MMI for the LABIHS simulator, currently under development using LabVIEW software suit. We then provide a comparison between the original and the proposed MMI development process.
