Frazer-Nash keeps ITER cool

摘要

Frazer-Nash has been appointed by the ITER Organisation to optimise the design solution for the ventilation of the port cells which will hold the experimental Test Blanket Modules (TBM) Systems, which are test facilities to demonstrate self-sustained tritium production for future large-scale fusion power plants. Due to the radioactive nature of tritium it is important the concentration within the TBM port cells is kept below the maximum acceptable limits, and at times can be reduced to low enough levels to allow entry to the TBM port cells for maintenance work. The port cell walls are predominately made from concrete - with a maximum operational temperature of 50℃ - so it is therefore essential to find a way to ventilate the cells to keep the temperature down, as well as reducing the level of tritium contamination down to acceptable levels.
