Study of the cooling of corium by water: MERELAVA device
Project: To support the deployment of the MERELAVA test device to study the cooling of corium by water under certain conditions, the design of a thermite-manufacturing workshop (powder mixture in glove box) and the integration of these new means within the COLIMA room of the PLINIUS platform (ICPE) as part of a project by the CEA Cadarache Physics and Modelling of Serious Accidents Laboratory (LPMA) to understand the behaviour of corium, generated from the nuclear reactor core’s, and to model the phenomena associated with the formation and progression of corium within the reactor
Aims and characteristics:
- To consider the specific requirements of the project under PED (classification and monitoring by ON)
- To manage the manufacturing of piping lines in 310S (qualification/manufacturing/radiographic testing)
- To carry out a PMA (Particular Material Appraisal) to approve the use of 310S according to PED
- To integrate client equipment within a space-limited environment
- To support studies, manufacturing, installation and testing services
- To assign a project engineer to ensure monitoring and documentation; a storekeeper/picker; a designer; a calculation engineer; a research office manager; a technical and production engineering manager; a qualified sheet metal worker; three qualified welders; a workshop manager; a qualified fitter; and a site manager
