Synergies Non linear responses

Different mechanisms at different

length and time scales

SP4 : Physical modelling and modelling-oriented experiments on structural materials

High irradiation dose

Aggressiveenvironment

structure & composition

Mechanical loading

High temperature

Physical understanding is a key for prediction of the behaviour of materials under

envisaged in-service conditions for safe operation and design of the Gen IV reactors

SP2Innovative high

temperature resistant steels

SP3Refractory Materials

Cross-cutting sub-programme

- WP 1: Determine and quantify the physical mechanisms that govern the property changes experienced by "conventional" steels selected in SP1 and their model alloys

3 Pilot Projects (2 support the MatISSE project)

- WP2 and WP3: Assist in the elaboration routes for innovative materials performed in SP2 and SP3. Early stage.

2 Task Forces (are working on new PP)

- WP4: Coordination/consolidation and sharing ressources. Development of a web portal by ENEA for sharing data and results, reporting etc…

Objectives & Topics reflect the other SPs on structural materials
