Mathematical Problems in the Simulation of Reactor Plants

摘要: The paper gives an overview of the mathematical problems encountered in simulation reactor plants, particularly with light water reactors. Major problem areas are: i) Numerical methods for solution partial differential equations, describing process models. Several topics are addressed: ways spatial discretisation which lead to efficient algorithms efficient time integration coupling different types model equations algorithms suitable use on multi-parallel processors. ii) Principals and quantification uncertainties influence results calculations. Several commonly used summarized. Criterions their discussed.
