Round robin and certification of Pu-based materials by electron probe microanalysis (EPMA)
Status
| Terminated |
- Planned from July 2007 till January 2009 |
Goals
Understanding the behaviour of nuclear materials components or fuels under all operating conditions (in-pile, accidental conditions or long-term storage conditions), requires a set of thermomechanic, neutronic or thermodynamic modelling tools. These approaches require experimental tests and studies associated with performing and adapting analytical techniques for irradiated materials. These techniques are still complex to master especially in a shielded environment and irradiated materials; for these reasons, the aim of the project is to develop a set of reliable and quantitative analytical methods on irradiated materials to support material studies in nuclear R & D (i.e. advanced nuclear fuels based on actinide carbides and nitrides) applied to electron probe microanalysis (EPMA).
This project follows the earlier ACTINET Call 04 04 which contributed i) the constitution of an EPMA network (nuclear and academic partners) and ii) the definition and implementation of the working directions proposed in the present project (i.e. preparation of 2 round robin tests).
Expected results
Expected impact on applied issues in the field of nuclear fission energy
- Coordination of analytical development in the field of nuclear analysis and capabilities of asking to the suppliers specific nuclear developments (2 new shielded EPMA in order and 2 or 3 devices in project)
- Constitution of an efficient and practical analytical network especially towards young researchers and technicians.
- Improvement of the accessibility of actinide facilities to the network for complementary analysis (physical and chemical analytical techniques).
- Ability to demonstrate by a quality approach and ISO certified samples, the reliability of Actinide measurements.
- Reduction of uncertainties on EPMA measurements of minor actinides and fission products by the constitution of suitable standardless software.
- Accumulation of reliable findings to support irradiated material studies for EPR, HTR, GFR, SFR nuclear research reactor and waste studies.
- Contribution to ISO quality certification for nuclear analytical laboratory with the constitution of reference standard samples.
- Demonstration of the capability and the interest to constitute an Analytical Network for Nuclear (Actinides and Inert) for some analytical techniques with the support of CEA/CETAMA.
Expected impact on long term integration
- Extension of this methodology to other analytical tools (surface analysis, chemical analysis) with the support of CEA/CETAMA.
- Opening the network to other nuclear framework (ACTINET and HOTLABSSA) and nuclear analytical laboratories (JRC Petten, Northern and Eastern Europe)
- Establishment of a community working on the analysis of nuclear materials including academic partners.
