This section collects a series of Case Studies performed by NINE experts. As “Case Studies,” they include specific and well-defined technical activities carried out in the framework of service contracts, with a diverse range of scopes and objectives and generally involving skills and competences from different technical areas.
In order to assist the reader with identifying the Case Studies of interest, a cross-reference table has been developed where each Case Study is assigned one or more of the following attributes:
•    Code and Methodology Development and Validation;
•    Licensing Applications;
•    Independent Assessment (Safety and Design);
•    Experimental Activities (indication is given of the relevant);
•    Technical Area;
•    Reference Technology;
