The linked PDF (page 14) has a few diagrams that can help infer vessel size, and the Wikipedia page for TSMR-LF1 also includes a decent floor plan and links to satellite images. Looks like a typical research reactor footprint, which means it may scale to be similar to existing LWRs at higher power.

For reference, a typical PWR may be ~3000 MWth.
Thanks for the info!
