One thing that' slightly worrying:

It seems like it's yet to be demonstrated that Triso fuel can withstand the highest recorded temperature inside a nuclear reactor. I get that the physically impossible quote is probably partially puffery, but IMO puffery is not appropriate when it comes to nuclear reactors.
