What do these attributes mean for common use cases?

This is an attribute check, not a project recommendation. Site, grid, licensing, fuel, security and economics still need project-specific analysis.

Common questionWhat this design data says
Grid electricity?77 MWe electrical nameplate in the current design snapshot.
Useful heat?Yes — the design is presented here with heat-use potential.
Remote / isolated deployment?Small-unit scale; site fit is project-specific.
Transportable system?No — this profile treats it as a fixed-site design.
Current programme phase?Regulatory / selection NRC-approved design

Programme status

NRC-approved design. No commercial unit operating.

Vendor pursuing multiple deployment opportunities.

Status describes the programme at the verification date. It does not imply commercial availability, licensing in your jurisdiction, construction certainty or guaranteed schedule.
