Steam is a sign of cooling system function . . . at ITER
Steam from one of ITER’s ten induced-draft cooling cells offers visual confirmation of a successful cooling system test, the ITER organization announced April 30. ITER’s cooling system features 60 kilometers of piping with pumps, filters, and heat exchangers that can pull water through at up to 14 cubic meters per second. Once fully operational, two cooling loops—one to remove the heat generated by the plasma in the ITER tokamak and one for its supporting infrastructure—will be capable of extracting up to 1,200 MW of heat.

Activation analysis was performed for the outboard (o/b) and inboard (i/b) blanket and shield of ITER. The options of using PCA or Tenelon were assessed. The o/b blanket and shield qualify as class C LLW. If Tenelon is used, it qualifies as class A waste. The i/b shield by itself qualifies as class C waste only if Tenelon is used. If PCA is used, then class C qualification can be realized if the i/b and o/b shields are disposed of together. The total amount of 14C produced in the coolant is 4650 Ci for LiNO3 and 54 Ci for LiOH. The Be/SS/W i/b shield results in a decay heat much less than that in an all W shield. Under adiabatic heat-up conditions, the PCA structure can withstand a L0CA and after one day the temperatures do no exceed 700°C.
