Our client, UKAEA, are developing the STEP fusion power plant, with the aim of being the first commercial fusion plant in operation. With HiETA technologies we entered and won a competition to design the diverter heat exchanger, which forms part of the wall in the very hottest part of the fusion chamber. Three other companies were also awarded contracts, with the best design progressing to trial.
The design and analysis work was completed sufficiently quickly that HiETA were able to produce a test piece within the overall three-month project duration. Our design was adjudged the most promising of the four alternatives and is now in the test phase.
