Descripción del proyecto
Facilitar la adopción de herramientas para desmantelar reactores de grafito
Todas las centrales eléctricas tienen una vida finita más allá de la cual no es económicamente viable tenerlas en funcionamiento. En este caso, deben desmantelarse, limpiarse y demolerse. El proyecto financiado con fondos europeos INNO4GRAPH desarrollará una serie de herramientas para poner fin a la actividad de centrales eléctricas. En concreto, diseñará modelos tridimensionales de escenarios de desmantelamiento, así como herramientas de medición de las propiedades mecánicas y físicas. En 2022, se probarán las herramientas y métodos del proyecto en un demostrador de central eléctrica de grafito a escala real en Chinon (Francia), lo cual facilitará su adopción y posterior mejora. La participación de todos los operadores europeos de reactores de grafito en el consorcio iniciará una era de excelencia en el campo del desmantelamiento de los reactores de grafito.
Objetivo
The decommissioning of closed graphite moderated nuclear reactors worldwide is still in its early stages with the majority of reactors in “safe store” condition. For these reactors, there are still considerable industrial and technical challenges that remain to be tackled even after more than 30 years of operational shutdown of the first unit. Challenges related to the dimension and complexity of the structure as well as costs for decommissioning urge for novel, more performant, safer and cost-efficient solutions for dismantling operations.
INNO4GRAPH aims at developing a set of physical and digital tools and methods to be used both upstream of dismantling operations (for material characterisation and decision-making) and during dismantling operations (for handling and cutting). Tools such as 3D modelling of dismantling scenarios, measurement tools for mechanical and physical properties, mock-ups of the graphite stack and laser-cutting during dismantling operations will be developed. To ensure the cost-efficiency of dismantling scenarios and tools, INNO4GRAPH partners will collect and compare existing cost data for tools, in reference with the different scenarios, to create a benchmarking database for a future decommissioning cost estimate. The launch by EDF of a full-scale graphite power plant demonstrator in Chinon, France, in 2022 will facilitate the uptake and further development of the tools developed during the project.
The participation of all European graphite reactor operators in the consortium will not only be the launch of a sector of excellence in the graphite reactor decommissioning field, but will also ensure a large uptake of results by the end-users and will contribute to achieve the highest impact both on scientific/technological, innovation and economic level.
