GRAPE : Graphical RELAP5-based Analysis Platform for Education/Engineering

GRAPE is an innovative platform for a nuclear plant simulation for education and engineering where reliable plant models for RELAP/SCDAPSIM code are available. With an intuitive and easy-to-use GUI, students can perform simulations using an engineering-grade system analysis code without deep knowledge of the calculation code itself.
Visualization capability of GRAPE makes it possible to show the calculation results from various angles with quite simple manners. Even novice users can obtain in-depth understanding of nuclear power plants in a short time.
GRAPE provides additional values for education and engineering with its flexibility and extensibility such as multiple language support, sensitivity analysis support with the built-in macro language, and incorporation of user-defined plant models.
