Abstract

The LECA-STAR is a CEA nuclear Hot Lab facility which is dedicated to RandD on irradiated fuels. It has been designed to analyze the behavior of a wide range of nuclear industrial and MTR fuel under irradiation. These capabilities are a key point in the fuel qualification/development cycle.The facility is divided in two parts, the LECA (Laboratoire d'Examens des Combustibles Actifs, 1964) and STAR (Station de Traitement, d'Assainissement et de Reconditionnement, 1994) which are dedicated to- Non-destructive and destructive examinations (PIE) and annealing tests on irradiated fuels of different types and geometry, in order to characterize and determine the fuel behavior. Collected data and mechanisms understanding are used to establish laws and models which allows predictive in service-behavior and performance.- Manufacturing of fuel rodlets from irradiated industrial rods for in-pile testing in MTR,- CEA irradiated spent fuel processing and packaging.Over 180 people work daily on the different processes and technical examinations tools available in the fifteen different hot cells (size up to 9m long) and in the LECA microanalysis laboratory which offers a unique and complementary combination of analytical equipment. The work of the staff is organized on the basis of the time slot of opening of the facility,( ie 6h-21h), in normal or shifted schedule either in round-the-clock operation, according to the function and type of activity.Inside the facility, the operating team insures the maintenance, operation and nuclearization of devices in compliance with the Safety and Security rules and is responsible for the deployment and supervision of the processes (design and manufacturing), with the aim to provide high availability for the activities of the experimental teams.Based on its current supply of services, and in view of the future CEA Jules Horowitz (JHR) reactor startup, the LECA-STAR launched actions to renew some of its equipment and launched an approach in order to upgrade its processes through innovative technologies.The presentation will aim at putting forward the prospects of the installation in connection with the future reactor JHR located on Cadarache site.
