Preparation for Lower Port Integration Engineering for ITER Diagnostic Systems in JADA

Abstract

In ITER, there are various ports at the upper, equatorial, and lower levels, which serve various purposes such as evacuation, heating, remote handling, and diagnostics. Since several diagnostics will be integrated in Lower Port #2 (LP#02), its procurement is in the scope of diagnostics. The integration engineering activities of LP#02 are included in the scope of Japan Domestic Agency (JADA) procurement because the dominant component, the Divertor Impurity Monitor (DIM), is procured by JADA. The components in the LP#02 procurement package are the diagnostic racks assembly, interspace assembly, port cell assembly and tooling. The integration of these components must minimize impacts on the divertor exchange procedure, and requires the assemblies to be manufactured as fully integrated components and interfaces. In the current status, which is between the conceptual design and signature of the procurement arrangement, JADA identified technical issues and implemented thermal and structural analyses within the specified design conditions.
