A nuclear data oriented interface code for processing applications

A new user interface code developed to facilitate the processing of evaluated nuclear data is presented. The CadTui package proposes an easy-to-use interface with the widely use processing and nuclear data codes. It was especially designed to simplify the complex relationships between an evaluation and its processing. In response to requests from users involved in reactor development programs, intuitive Unix commands relying on Monte Carlo techniques were implemented to propagate the uncertainty of the model parameters to integral calculations at a given dilution cross section.
