Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

A genetic algorithm (GA)-based method has been developed to analyze Charge-eXchange Recombination Spectroscopy (CXRS) data and provide in-between shot evaluation of the ion temperature profile during Tore Supra experiments. The GA method proposed here proves to be fast and fairly accurate, even when analyzing low signal-to-noise data. Simulations using theoretical signals suggest that the ion temperature and the plasma rotation velocity are expected to be determined with a precision better than 10% for a noise level up to 5% of the spectrum peak. The good agreement with the commonly used KS4FIT code when analyzing CXRS experimental data - typically within 30% for ion temperature measurements - confirms the efficiency of such an analysis tool.
