Rolls-Royce SMR earns second U.K. assessment
The small modular reactor design from Rolls-Royce has cleared step two of the United Kingdom’s generic design assessment (GDA) and is moving to the third and final step.
The company announced its progress and lauded “Rolls-Royce SMR’s position ahead of any other SMR in Europe” in a July 30 press release. Rolls-Royce SMR touts its ability to deliver new nuclear power based on proven technology, providing a “factory-built” power station to provide enough energy for a million homes for a 60-year stretch.

A follow-up is done to earlier work on the conversion of isotopic waters to hydrogen isotopes, and it involves the reaction behavior of water vapor with Zr(V0.5Fe0.5)2 getter alloy under water vapor flow conditions. The efficiency of the alloy, for the conversion of H2O and D2O to H2 and D2, respectively, has been measured at different reactor pressures in the range of 10 to 330 Pa for different alloy temperatures in the range of 150 to 400°C and with hydrogen and oxygen concentrations in the alloy ≤ 250 mmol/mol of alloy. The conversion efficiency was measured to be in the range of 25 to 35% at reactor pressures of ≈250 Pa for water vapor flow rates of ≈0.3 µmol/g of alloy per second, while it was found to be in the range of 70 to 80% at reactor pressures ≤20 Pa with flow rates of ≤0.02 µmol/g of alloy per second. These experiments demonstrate the feasibility of tritiated water vapor conversion to tritium using metallic getter alloys under quasi-steady-state conditions; this feasibility is very relevant to the fusion reactor fuel cycle.
