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.

Edge-localized mode (ELM) simulation experiments were held on the quasi-stationary plasma accelerator QSPA-T to study the formation of plasma-facing material (PFM) erosion products. Parameters of the deuterium plasma heat loads in QSPA-T were close to those expected during transient events in ITER. A diagnostic system for measuring the deposition rate of the erosion products with resolution time of 0.02 ms (pulse duration 0.5 ms) was designed. It allowed defining the deposition rate dependence on time and property changes of the deposited film during the pulse. The average deposition rate in QSPA-T under exposures to ultra-short D plasmas was in the range of (0.1 to 100)×1019 at·cm2·s−1, which was much higher than that for stationary processes. It has been found that deuterium concentration in the deposited W films depends on substrate temperature and deposition rate approximately in the same way as for stationary processes. As the substrate temperature and deposition rate increased, the D/W atomic ratio in the W films decreased. For describing the evolution of the D/W ratio with the substrate temperature and the tungsten deposition rate, an empirical equation proposed by De Temmerman and Doerner (J. Nucl. Mater., 2009), but with alternative parameters, has been used.
