Daniel Jassby is a tiresome crank. Always quoted in the media as the sole critic of fusion. He runs a website devoted to blowing things out of proportion. In this article, he says that SPARC and ITER will both achieve first plasma around the same date (2025) but that SPARC will take another ten years to burn DT fuel because ITER is taking ten years.
ITER is taking ten years because the equipment required for DT operation won't be installed until 2035, after their second maintenance shutdown. SPARC is intended to progress to DT operation as soon as possible after first plasma assuming all the equipment checks out.
He poo-poos tritium breeding, referring to an article he wrote 5 years ago about the faults of a solid blanket, neglecting to mention that the ARC design has been based on a liquid blanket.
If he wants to criticize the MIT/CFS SPARC/ARC design, he should by all means just go ahead and do so, but this lazy approach of his is just plain dumb and tiresome.
