FIDES Cross-Cutting Pillars

Member Area (password protected)

 

The FIDES framework is designed to do more than just produce data on transient fuel behavior and safety related issues. The FIDES framework is supported by three cross-cutting pillars:

  • Data Preservation and Quality Assurance
  • Training and Education
  • Modeling and Simulation

Improving experiments through modeling

P2M experimenters have collaborated with over 40 modelling experts in an exercise using archive data to assess their code’s ability to predict fuel melting. Through this modelling exercise, a better understanding of the boundaries of existing models has been developed. The exercise also allowed experimenters to identify specific measurement and examination activities that could produce data to improve fuel melting behavior models.

HERA experimenters will also collaborate closely with modelers. A modeling exercise is being conducted alongside the HERA experiments, beginning with blind simulation of the planned experiments. The results will help experiment designers finalize the details of the experiment. The exercise will also help modelers see where their models are good at predicting the complicated behavior of fuel during an RIA and reveal where the models need improvement.

Looking to the future

As an international research collaboration, FIDES is relatively unique in its ability to consider research opportunities independent of a specific research facility. The design of FIDES allows members to benefit from a portfolio of in-pile facilities. With this in mind, the members of FIDES have launched an initiative to write a 10-year strategic plan that can define at a very high level key research needs in a variety of technical disciplines. This strategic plan would then form the basis to consider future proposals.

The writing of the strategic plan will leverage expert perspectives from industry, safety authorities and laboratories to develop a high level vision of the priorities of research. They will define research needed to answer pressing safety questions as well as research needed to support innovation in the nuclear industry. They will also consider how to best utilise existing irradiation testing infrastructure and how to safeguard the knowledge required to conduct nuclear fuel research.
