Yes, this is about pebble bed reactors. From the article: The Xe-100 is a small pebble-bed reactor that is designed to produce just 75 megawatts of power.

I should add that I'm thrilled steps are being made to make these a reality.
- api 6y agoSeems like the pebbles are much smaller in these. I recall one very mundane but difficult issue with previous pebble bed reactors was pebbles jamming and other mechanical problems with the fuel. These seem like they'd flow like that weird pseudo-sand stuff in kids toys.
- pjscott 6y agoThese very small fuel particles are embedded in larger graphite structures with whatever geometry is convenient for handling. (Pebble bed pebbles are one such possibility, and PBRs have been made which use TRISO-based fuel pebbles.)
