JP Nuclear Materials
Sub-programme 4 - Physical modelling and modelling-oriented experiments on
structural materials
The Joint Programme for Nuclear Materials of the European Energy Research Alliance (EERA JPNM)
Cristelle Pareige (CNRS)EERA JP MS Stakeholder Meeting10th of September 2014, Brussels

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
