Preliminary Thermal and Hydraulic Analysis on the ITER Upper Diagnostic Port Plug During Normal Operation and Baking

On the theoretical–numerical study of the ITER Upper Port Plug structure hydraulic behaviour under steady state and draining and drying transient conditions

“…They are housed inside 12 upper and 6 equatorial ports, being supported, like cantilevered beams, at the flanges of these ports through bolted joints [1].…”

Numerical simulation on bake-out of the ITER diagnostic upper port plug

“…The baking time for the outdated diagnostic upper port plug was calculated in the previous study with the assumption that the water is supplied at the fixed temperature (240 • C) from the beginning [3]. The cooling water system is, however, likely to feed the water of which the temperature varies gradually from room temperature to 240 • C. The baking time will depend on the temperature ramp-up rate of the water.…”
