Comparative thermal analysis of the VVTS panels with circular external pipes and extruded internal pipes


Completed orders:

ITER Team (Garching, Germany) - International Thermonuclear Experimental Reactor


The main objective of the performed thermal analysis is to compare a thermal performance of the different design of the VVTS panels: (a) panel with extruded internal pipes (Fig. 4.15); (b) panel with circular external pipes attached to the panel by 2 mm stainless steel brackets and (c) panel with circular external pipes attached to the panel by stainless steel brackets cladded with 0.5 mm copper (Fig. 4.16).

The obtained results allow us to draw the following general conclusion:
The proposed by RF PT team VVTS panel design (with welded extruded pipes) as well as the design with circular pipes attached by 2 mm stainless steel brackets cladded with 0.5 mm copper are characterized by enhanced thermal insulation performance against reference design and could be recommended for the ITER application.
