I think it safe for me to relay that there was another Mizuno replication 1 month ago (12/4) at a Japanese University. The "under-reported" COP was 1.7, and was probably more likely 2.0. I could not do justice with the graphs, but I can say it made Alan Smith excited.
It was not clear to me however, what year/model reactor that result was based on. From my understanding, Mizuno gives out different reactors for testing, based on the experience level of the end user.
Some, like our one French, and one Swedish friends, get the older models because they are both so capable, but the less experienced get the newer reactors. There is more of course.
Is there any way we can see some numbers or graphs? Will there be any publication?
