Description:

The STEP Fuel Cycle is the subsystem responsible for recovering, purifying and supplying tritium to the STEP fusion reactor. Tritium is present in a variety of forms, phases and compositions, including tritiated water. Vapour-phase electrolysis techniques such as solid-oxide electrolysis have been identified as a suitable technique for processing small quantities of tritiated water. The scope is to deliver the conceptual design of an electrolyser system (electrochemical cell or stack). This includes, but is not limited to, components of the electrolyser: electrolytes, electrodes, interconnects, separators, electrical connections, vessels, structural components, seals, gaskets, heating elements, inlet/outlet pipes, ports, flanges and instrumentation. The scope does not include conceptual design of ‘Balance of Plant’ equipment such as power supplies, pumps, purification stages, boilers, compressors or dehumidifiers. However, the impact on balance of plant equipment must be considered in design decisions for the electrolyser itself.

The scope is structured into three sequential phases with interim milestones. These phases will progressively develop technical understanding, validate assumptions, and converge on agreed technical content.
