Parallel Computation Research of Neutron Time-Spatial Kinetics Program for Fast Reactor

The neutron time-spatial kinetics program for fast reactor, which is based on the neutronics analysis system (NAS) for fast reactor, can be used to analyze the three-dimensional transient neutronics. Combining the characteristics of the program and the development of the modern computer, the parallel computation, which speeds up the calculation greatly, was introduced in this paper.
