Japan Atomic Energy Agency promotes development of innovative analysis methods and models in fundamental studies for next-generation nuclear reactor systems. In order to efficiently and effectively reflect the latest analysis methods and models to primary design of prototype reactor and/or in-core fuel management for power reactors, a next-generation analysis system MARBLE has been developed. In the present study, functionalities for debugging have been enhanced by preparing an error handling mechanism in order to provide higher level of usability for users of the framework. Other functionalities have been also developed to deal with complex calculation routes with corrections such as analysis of critical experiments by introducing a mechanism for flexible handling of computational procedures.
