RHS will be contaminated during exposure inside ITER Vacuum Vessel with activated dust, tritium and beryllium.
The MPD provides the means for deployment and handling of in-vessel tools or components inside the vacuum vessel (VV) for dust and tritium inventory control, in-service inspection, leak localization, and in-vessel diagnostics.
An 8- to 10-ounce cotton canvas is recommended to protect your vessel from grime, dust, insects and bird excrement.
The experiments were executed in a standard 20 L vessel apparatus used for dust explosion testing.
This paper details an approach for calibrating a new 36-l dust explosion vessel by analyzing the turbulent decay following transient dispersion of dust clouds using computation fluid dynamics (CFD).
By modifying the dispersion system and the ignition delay time, and hence the flow field and turbulence intensity during the combustion process, the 20-l dust explosion vessels have been calibrated to give results comparable to the 1-m3 vessel as prescribed in the former standard ISO-61844).
Body movements over open vessels were avoided to prevent dust or particulate contamination.
The In-Vessel Viewing and Metrology System (IVVS) is a fundamental tool for the ITER machine operations, aiming at performing inspections as well as providing information related to the erosion of in-vessel components, which in turn is related to the amount of mobilised dust present in the Vacuum Vessel.
The aim is to clarify the overpressure characteristics in a vessel and relief pipe, during aluminium dust explosion venting, especially when a burn-up phenomenon occurs.
During unloading of the vessel representative samples of the accompanying dust are collected and pooled into 24 subsamples, which are analyzed for each vessel.
