Summary:Flow distribution on the piping network of ITER Thermal Shield (TS) is analyzed and orifice installation is suggested for attenuating flow mal-distribution. Flow test is performed for a TS segment to verify the analysis model. Room temperature nitrogen gas passes through the cooling pipe on TS segment with test flow rate which is equivalent to the actual operating condition of TS. Flow rate is controlled by a thermal mass flow controller and pressure drop between the inlet and the outlet of the pipe routing is measured by a differential pressure gauge. Test result is compared with the analysis one to check the validity of the analysis model for the real manufactured TS segment. The flow test is also conducted for the fabricated orifices. The loss coefficient of the orifice is compared with that used in the analysis. The loss coefficient correlation for the fabricated orifices is obtained from the test results.
