No. They have claimed to have done so. Far as I know, they have accomplished nothing worthwhile in LENR at all. Claims are not accomplishments else Rossi would be very accomplished in something other than conning people.
Nanospire has always been a legitimate business with clients. Nowadays, they seem to have put their LENR days behind them, and gotten on with life. I think they even dropped any reference about that radiation exposure story from their website.
