Modeling principles and computing technology for high-speed simulation of LWR transients

摘要

The plant analyzer recently developed at Brookhaven National Laboratory embodies the unique combination of high simulation fidelity, with convenient interactive access, much faster than real-time simulation speed and low cost. This has been achieved through a deliberate match of modeling techniques with modern, special-purpose minicomputer architecture, designed for high-speed simulations of complex systems. The BNL Plant Analyzer is a powerful engineering tool for carrying out, routinely and cost-effectively, safety analyses, optimizations of procedures, parametric studies to obtain safety margins and for generic training. It is also applicable for operator assistance through plant performance monitoring, automatic fault diagnostics and on-line support during emergencies. This paper presents five modeling principles, the criteria for selecting numerical integration techniques and the key features of the special-purpose peripheral processor, the AD10 of Applied Dynamics International. The paper presentation is followed by a remote access demonstration of the plant analyzer.
