Temperature & DPA have to be talked about together. I think Abdou's point is that you can replace the blanket more often and target ~20 DPA to reduce the mean-time-between-failures (MTBF). From the PDF:
"Results show: anticipated MTBF is hours/days (required is years), and MTTR is
3-4 months (required is days), and availability is very low < 5%"
I don't have a problem with talking about MTBF and replacing blankets etc but we are talking about research, not a reactor.
Also of note look at the MTBF of magnets and cryogenics in this system! (1.14years and 0.57 years)
