Against a background of recent advances in computer technology, it has become possible to perform simulations using more precise computational techniques. As one of its basic technologies for supporting plant development, Hitachi has developed simulation technology able to perform detailed modeling of the phenomena inside nuclear power plants. Nuclear power plants are large systems comprising numerous different equipment in which a range of different phenomena interact. Not only can simulators improve development efficiency and provide an understanding of the physical processes involved in complex phenomena, they can also be used to predict what will happen under different operating conditions or if new equipment is introduced. Feeding the simulation results back into the plant and equipment design process helps improve the performance and reliability of the associated products.
