NECTAR (NPA) program and reference manual

NECTAR is a general data base driven graphic animation and simulation system. This system originated as the NPA (Nuclear Plant Analyzer). It was originally designed to be used by the Nuclear Regulatory Commission (NRC) for the analysis of nuclear plant data produced by large nuclear modeling codes. It ws subsequently designed and developed as a general purpose graphic animation system to be used with any type of time series data. This system is designed to allow ''real time'' execution and analysis of data from large modeling and simulation codes or the replay of past simulations or experimental data. This manual gives an in depth description of the structure, supporting concepts, processors, and individual routines used in the NECTAR system. It is designed as a program and reference manual. As such, the level of detail and technical descriptions are intended primarily for the experienced system analyst.
