Nuclear Engineering and Simulation Technology

Abstract

A review is made on the application of the simulation technology in the field of the reactor engineering. Simulation technology in a wide sense is classified in four types: (a) solid model used in earthquake-proof tests, loss-of-coolant tests and so forth, (b) model based on physical ana1ogy such as reactor simulator by optical analogy, (c) analog computer simulation and (d) digital computer simulation. There is a variety in the purpose of the simulation: prediction of various phenomena such as power distribution and fuel burnup, training of the operators, safety analysis and so forth. The role and importance of digital computer simulation is increasing, and the development of more sophisticated display, such as computer graphics, as well as faster computer by means of parallel processing is being pursued.
