CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE

The CNRS (National Centre for Scientific Research) is a government-funded research organisation under the administrative authority of the French Ministry in charge of research. The missions of CNRS, defined by governmental decree, are to evaluate and carry out research capable of advancing knowledge and bringing social, cultural, and economic benefits to society; to contribute to the application and promotion of research results; to develop scientific information; to support research training and to participate in the analysis of the national and international situation of science and its perspectives for evolution in view of contributing to the development of the national research policy.
As the largest fundamental research organisation in Europe, CNRS is involved in all fields of knowledge. Interdisciplinary programs and actions offer a gateway into new domains of scientific investigation and enable CNRS to address the needs of society and industry.
CNRS is organised in more than 1100 research units spread throughout France. These units are either intramural or in partnership with universities, other research organisations, or industry. The financial, legal and administrative management of these units is concentrated in 19 Regional Offices of CNRS.
CNRS encourages collaboration in national, European, and international projects and provides a strong administrative support to such projects, with dedicated staff on financial, legal, and administrative issues.
According the 5th FP7 Monitoring Report – 2011 published on 29th August 2012, the CNRS is the research organisation with the highest number of participations (961) in FP7 signed grant agreements during the period 2007-2011.

Role in the project

SOTERIA is managed by the 19th Regional Office of CNRS (Normandy) which is fully experienced in this field. In SOTERIA, 5 research units are involved:
GPM UMR 6634
The GPM is involved in WP 2 and 3: In WP2, the GPM is working on the effect of flux on microstructural evolution of internals and on the microstrucre of RPV steels or model alloys irradiated at high fluence. In WP3, the GPM is working on the influence of metallurgical heterogeneities on microstructural irradiation response of 16MND5 vessel steel. In both cases, the main activities of the GPM are the nanoanalysis (APT, STEM) of irradiated model alloys and steels for a better understanding of irradiation ageing mechanisms.
CSNSM – UMR8609
The CSNSM is involved in WP2 and 3: In WP2, the CSNSM is involved in the study of the effect of neutron flux on the irradiation – induced nanostructure of RPV steels or model alloys. In  WP3, the CSNSM is involved in the study of  the influence of metallurgical heterogeneities on microstructural irradiation response of 16MND5 vessel steel. In both cases, the main activities of the CSNSM are the TEM investigations of irradiated model alloys and steels and material ion irradiation when planned.
UMET – UMR8207
The UMET is involved in WP5: the UMET is in charge - in close collaboration with EDF - of the development and improvement of nanostructure models for RPV and internals, using Density Functional Theory, Kinetic Monte Carlo and Rate Theory models. The sink strengths will be determined using phase field models.
CEMHTI – UPR3079
This unit carries out the following activities:
• Positron annihilation spectroscopy in RPV models WP1.
• Positron annihilation spectroscopy in 16MND vessel steels WP3.
• He irradiations for the study of the Effects of Helium on IASCC Susceptibility in collaboration in WP4.
LMA – UPR7051
In close collaboration with IRSN, the role of the LMA in SOTERIA is to develop and to apply numerical full-field methods to study the mechanical behavior of  polycrystalline viscoplastic materials in presence of pores and cavities.
