Abstract
The application of new technologies and programming tools represents a challenge and an economic risk for companies, which not all are prepared to assume. This paper presents the application of RT-CORBA in the development of software for Nuclear Power Plant Simulators used for the training of future operators in a safe way. The developed software has allowed the adaptation of previous simulation software to new methodologies and standards; and the creation of new applications, aiming at the building of reusable components with real-time constraints in future projects.
