What is being bought

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.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 71. The category anchor is Engineering services (71300000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 713,8973 median · 30.6 average (1,068 of 3,897 with a bid count)3.9 average (1,179 of 3,897 with named award suppliers)Not published

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
